Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicle processing, and particularly relates to a processing device and a processing system. BACKGROUND

[0002] In the processing of a vehicle, a chassis and an upper vehicle body need to be spliced to form a complete vehicle body. In the process of splicing the chassis and the upper vehicle body, the relative positions between the chassis and the upper vehicle body usually need to be adjusted so that the splicing of the chassis and the upper vehicle body can meet the precision requirements.

[0003] In the current splicing device, the relative position of the chassis is usually adjusted. For a chassis with a large weight or an integrated chassis, the structure required for adjusting the chassis is relatively complex, the strength and bearing capacity of the structure are required to be relatively high, the splicing efficiency is relatively low, and the cost of the device is relatively high. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the application provides a processing device and a processing system, which can alleviate the problem of low adjustment efficiency caused by the complex position adjustment structure of the current chassis.

[0005] In a first aspect, an embodiment of the application provides a processing device for splicing a chassis and an upper vehicle body, the processing device comprising:

[0006] a lifting structure configured to support the chassis, a slide rail structure comprising a fixed slide rail and a floating slide rail, the fixed slide rail extending along a first direction, the floating slide rail being disposed on one side of the fixed slide rail along the first direction, and the length direction of the floating slide rail being parallel to the first direction, the floating slide rail being configured to be movable at least along a second direction, the second direction being disposed at an angle with the first direction, and a lifting appliance configured to support the upper vehicle body, the lifting appliance being movably connected to the slide rail structure, the lifting appliance being configured to be movable along the fixed slide rail and the floating slide rail and to be able to stop on the floating slide rail so as to make the upper vehicle body relative to the chassis.

[0007] In the technical solution of the embodiment, the slide rail structure comprises the fixed slide rail and the floating slide rail, and the floating slide rail is movable relative to the fixed slide rail. In the case where the lifting appliance moves to the floating slide rail, the lifting appliance is movable relative to the fixed slide rail, so that the upper vehicle body is movable relative to the chassis, thereby facilitating the adjustment of the position of the upper vehicle body relative to the chassis. Meanwhile, the corresponding structure for position adjustment is disposed at the lifting appliance and the floating slide rail, the lifting of the chassis and the position adjustment are separated and disposed at different positions, thereby alleviating the problem of complex lifting structure, reducing the strength requirement of the corresponding structure for position adjustment, reducing the cost of the device, simplifying the complexity of the lifting structure, and facilitating the improvement of efficiency.

[0008] In some embodiments, the slide rail structure further includes a guide slide rail extending in a second direction, the guide slide rail being disposed on the side of the floating slide rail away from the lifting structure; the floating slide rail is movably connected to the guide slide rail.

[0009] The technical solution of this embodiment provides some specific structures of the slide rail structure, such that the slide rail structure includes a guide slide rail to guide the movement direction of the floating slide rail; under this setting, the lifting device can move along the first direction, and the floating slide rail can move along the second direction, so that the upper body on the lifting device can move in the first and second directions, thereby facilitating the adjustment of the position of the upper body relative to the chassis.

[0010] In some embodiments, the number of guide rails is at least two, and each guide rail is spaced apart along a first direction.

[0011] In this embodiment, the number of guide rails is two, so that the floating rail can slide more stably along the guide rail; at the same time, the guide rail can provide more stable support for the lifting device through the floating rail.

[0012] In some embodiments, the floating slide rail and the fixed slide rail are spaced apart.

[0013] In this embodiment, the floating slide rail and the fixed slide rail are spaced apart to reduce the possibility of collision between the floating slide rail and the fixed slide rail during operation.

[0014] In some embodiments, the processing apparatus further includes a centering structure for driving the floating slide rail to an initial position; when the floating slide rail is in the initial position, the lifting device can move from the floating slide rail to the fixed slide rail.

[0015] In the technical solution of this embodiment, a centering structure is set so that the floating slide rail can return to its initial position, so that the lifting device can carry the assembled chassis and upper body to the next process, and also facilitate the next lifting device to drive the upper body to the floating slide rail.

[0016] In some embodiments, the centering structure includes at least two centering components disposed on both sides of the floating slide rail along a second direction, and the centering components are configured to drive the floating slide rail to move along the second direction to an initial position.

[0017] The technical solution of this embodiment provides some specific structures for centering. Centering components are provided on both sides of the floating slide rail. Under this configuration, when the floating slide rail moves along the guide slide rail to either side, the corresponding centering component can drive the floating slide rail back to the initial position.

[0018] In some embodiments, the centering component includes a first driving member and a pusher connected to the first driving member. The first driving member is used to drive the pusher to move in a second direction. The pusher includes a base and a pusher wheel rotatably connected to the base. The base is connected to the first driving member. The axis of the pusher wheel is perpendicular to the first direction and the second direction. The pusher wheel is used to abut against the floating slide rail.

[0019] The technical solution of this embodiment provides some specific structures of centering components, such that the centering components include a first driving member and a pushing member, so that the first driving member can drive the pushing member to move and push the floating slide rail back to the initial position through the pushing member; the pushing member includes a base and a pushing wheel, so that the pushing member can not only push the floating slide rail to reset, but also reduce the friction between the pushing member and the floating slide rail, thereby reducing the damage between the pushing member and the floating slide rail.

[0020] In some embodiments, a force-bearing member is connected to the floating slide rail, and the centering component is configured to push the force-bearing member to move in a second direction.

[0021] In the technical solution of this embodiment, a force-bearing component is set on the floating slide rail so that the centering component can drive the floating slide rail to move by pushing the force-bearing component, thereby reducing the interference of the centering component on the movement of the lifting device on the floating slide rail.

[0022] In some embodiments, there are two fixed slide rails, and the two fixed slide rails are respectively located on opposite sides of the floating slide rail along the first direction.

[0023] In this embodiment, the number of fixed slide rails is two, so that the lifting device of the previous process and the lifting device to be moved to the next process can move on different fixed slide rails, thereby reducing mutual interference and improving efficiency.

[0024] In some embodiments, the processing apparatus further includes a positioning structure; the positioning structure is configured to move relative to the lifting structure to fix the relative position of the spreader and the lifting structure, and / or fix the relative position of the upper body and the chassis.

[0025] In the technical solution of this embodiment, a positioning structure is set up to adjust the relative position of the straightening lifting device and the lifting structure, and to adjust the relative position of the straightening chassis and the upper body, so that the splicing accuracy of the chassis and the upper body can meet the requirements.

[0026] In some embodiments, the lifting device includes a lifting device body having a first positioning hole; the positioning structure includes a first positioning component, the first positioning component including a first positioning member, the first positioning member being configured to move relative to the lifting structure to insert into or retract from the first positioning hole.

[0027] The technical solution of this embodiment provides some specific structures for positioning structures, such that the positioning structure includes a first positioning component, which adjusts the relative position between the lifting device and the lifting structure so that the lifting device can be directly aligned with the lifting structure, thereby facilitating the reduction of positional errors between the chassis and the upper body.

[0028] In some embodiments, the first positioning member includes a first fixing part and a first guide part connected to the first fixing part. The first guide part is disposed on the side of the first fixing part facing the lifting device. In the direction of movement of the first positioning member, the first guide part is gradually reduced from the first fixing part toward the lifting device.

[0029] The technical solution of this embodiment provides a specific structure of some first positioning components, such that the first positioning component includes a first guide portion and the first guide portion is a tapered structure. During the process of the first guide portion being inserted into the first positioning hole, the first guide portion can guide and adjust the position of the lifting device so that the lifting device can be aligned with the lifting structure, thereby facilitating the reduction of positional errors between the chassis and the upper body.

[0030] In some embodiments, the first positioning component further includes a second driving member connected to one end of the first positioning member away from the lifting device, and the second driving member is used to drive the first positioning member to insert into or retract from the first positioning hole.

[0031] The technical solution of this embodiment provides some specific structures of the first positioning component and sets a second driving member to drive the first positioning member to insert or withdraw from the first positioning hole, thereby facilitating the control of the movement state of the first positioning member; at the same time, the second driving member can also provide sufficient power so that the first positioning member can better adjust the relative position of the straightening lifting device and the lifting structure.

[0032] In some embodiments, there are two first positioning components, and the two first positioning components are disposed on opposite sides of the lifting structure along the second direction; there are two first positioning holes, and the two first positioning holes correspond to the two first positioning components respectively.

[0033] In the technical solution of this embodiment, the number of first positioning components is two, so that the lifting device can be subjected to force more evenly, and at the same time the load of a single first positioning component can be reduced.

[0034] In some embodiments, a second positioning hole is provided on the upper body; the positioning structure includes a second positioning member connected to the chassis, and the second positioning member is configured to move synchronously with the lifting structure to insert into the second positioning hole.

[0036] In some embodiments, the second positioning member includes a second fixing part and a second guide part connected to the second fixing part. The second guide part is disposed on the side of the second fixing part facing the lifting device. In the movement direction of the second positioning member, the second guide part is gradually narrowed from the second fixing part toward the lifting device.

[0037] The technical solution of this embodiment provides some specific structures of the second positioning component, such that the second positioning component includes a second guide portion and the second guide portion is a tapered structure. During the process of inserting the second guide portion into the second positioning hole, the second guide portion can guide and adjust the position of the upper vehicle body so that the upper vehicle body can be aligned with the chassis, thereby facilitating the reduction of positional errors between the chassis and the upper vehicle body.

[0038] In some embodiments, the processing apparatus further includes a carrier for supporting a chassis, the carrier being configured to move onto a lifting structure for being lifted by the lifting structure.

[0039] In the technical solution of this embodiment, a carrier is provided, and the chassis is supported by the carrier to facilitate the movement of the chassis from the previous process to the lifting structure.

[0040] In some embodiments, a second positioning hole is provided on the upper body; the positioning structure includes a second positioning member connected to the carrier member, and the second positioning member is configured to move synchronously with the lifting structure to insert into or retract from the second positioning hole.

[0065] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0066] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0067] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0068] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0069] In the description of the embodiments of this application, the technical terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0070] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0071] During vehicle manufacturing, the chassis and upper body need to be assembled to form a complete vehicle body. Currently, in the assembly process of the chassis and upper body, the upper body needs to be transferred to the chassis using a lifting device, and then the chassis is lifted using a lifting platform or other structure to assemble the chassis and upper body.

[0072] Due to the structure of the lifting equipment, the position of the upper body is difficult to determine during the process of supporting and transporting the upper body, and it is easy to have a certain deviation. These deviations will cause the installation positions of the chassis and the upper body to be misaligned during the assembly process, which will make it difficult for the chassis to be assembled with the upper body, or the assembly error will be difficult to meet the requirements.

[0073] Therefore, during the assembly of the chassis and the upper body, it is usually necessary to adjust the relative positions between the chassis and the upper body so that the mounting position of the chassis can be aligned with the mounting position of the upper body, thereby ensuring that the assembly of the chassis and the upper body can meet the precision requirements and installation needs.

[0074] To meet the requirements for the alignment and precision of the chassis and upper body, a floating structure capable of adjusting the chassis position can be installed on the lifting platform. However, for integrated chassis, structures such as the suspension and battery pack are all mounted on the chassis, resulting in a relatively heavy overall weight. In this case, adjusting the chassis position requires a more complex structure with higher structural strength. This increases the operational difficulty and time required for the floating structure, reduces processing efficiency, and also increases the cost of the positioning structure.

[0075] Based on the above considerations, in order to alleviate the problem of low adjustment efficiency caused by the complexity of the current chassis position adjustment structure, this application provides a processing device, which is provided with a slide rail structure, and the slide rail structure includes a floating slide rail and a fixed slide rail. The floating slide rail can move relative to the fixed slide rail in a second direction. At the same time, when the lifting device is located on the floating slide rail, the lifting device can also move in a first direction, that is, the position of the lifting device relative to the lifting structure can be adjusted in the first direction and the second direction.

[0076] In this processing device, when the lifting device moves onto the floating slide rail, this arrangement allows the lifting device to move relative to the fixed slide rail, enabling the upper vehicle body to move relative to the chassis, thus facilitating the adjustment of the upper vehicle body's position relative to the chassis. Simultaneously, this arrangement places the corresponding position adjustment structure at both the lifting device and the floating slide rail, separating the chassis lifting and position adjustment and placing them in different locations. This alleviates the problem of complex lifting structures, reduces the strength requirements of the corresponding position adjustment structure, lowers the cost of the device, simplifies the complexity of the lifting structure, and improves efficiency.

[0077] The processing apparatus disclosed in this application can be used for processing various vehicles, including large cars, small cars, special-purpose vehicles, etc. For example, according to vehicle type, a car can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0078] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0079] Firstly, reference Figure 1 , Figure 2This application provides a processing device 100 for assembling a chassis 200 and an upper body 300. The processing device 100 includes a lifting structure 10, a slide rail structure 20, and a lifting device 30. The lifting structure 10 supports the chassis 200. The slide rail structure 20 includes a fixed slide rail 21 and a floating slide rail 22. The fixed slide rail 21 extends along a first direction, and the floating slide rail 22 is disposed on one side of the fixed slide rail 21 along the first direction, with its length direction parallel to the first direction. The floating slide rail 22 is configured to be able to move at least along a second direction, which is at an angle to the first direction. The lifting device 30 supports the upper body 300 and is movably connected to the slide rail structure 20. The lifting device 30 is configured to move along the fixed slide rail 21 and the floating slide rail 22 and to remain on the floating slide rail 22, so that the upper body 300 is opposite to the chassis 200.

[0080] In the diagram, the X-axis is the first direction, the Y-axis is the second direction, and the Z-axis is the direction of movement of the lifting structure 10 and the lifting chassis 200.

[0081] The upper body 300 refers to the structure in the vehicle that provides overall support. The upper body 300 can also provide interior space for passengers and cargo. The upper body 300 may include structures such as the roof, side panels, front panel, and rear panel. The chassis 200 refers to the structure in the vehicle that provides the mounting base for other components. The chassis 200 may include the frame, as well as the suspension system, steering system, braking system, battery device, etc.

[0082] The lifting structure 10 refers to the structure in the processing device 100 used to support and lift the chassis 200. After the chassis 200 is placed on the lifting structure 10, the lifting structure 10 can support and raise the chassis 200 so that the chassis 200 can be close to the upper body 300, thereby facilitating the workers to assemble the chassis 200 and the upper body 300. The lifting structure 10 may include cylinders, hydraulic cylinders or other drive structures to lift the chassis 200.

[0083] The lifting device 30 refers to the structure in the processing device 100 used to support or suspend the upper body 300. The lifting device 30 can support or suspend the upper body 300 from other positions and move the upper body 300 to the top of the lifting structure 10 so that the upper body 300 can be assembled with the chassis 200 lifted by the lifting structure 10. The lifting device 30 can transfer the upper body 300 to the top of the lifting structure 10 from the previous process of the processing device 100. The lifting device 30 can also transfer the upper body 300 and the chassis 200 to the next process after the chassis 200 and the upper body 300 are assembled.

[0084] For example, the lifting device 30 can move the upper body 300 to above the lifting structure 10 along the Z-axis direction. At this time, the lifting structure 10 can lift the chassis 200 along the Z-axis direction and bring it close to the upper body 300 so that the workers can assemble the chassis 200 and the upper body 300.

[0085] The slide rail structure 20 refers to the structure in the processing device 100 used to support the lifting device 30 and guide the movement of the lifting device 30. The lifting device 30 can move along the slide rail structure 20 and move above the lifting structure 10, that is, at least a part of the slide rail structure 20 is located above the lifting structure 10.

[0086] The fixed slide rail 21 refers to the relatively fixed part of the slide rail structure 20. The fixed slide rail 21 is fixed relative to the ground, the lifting structure 10, etc. The fixed slide rail 21 can be fixed to the ground, wall or other positions by brackets or other structures. The cross-sectional shape of the fixed slide rail 21 can be I-shaped, U-shaped or other shapes. According to the position arrangement of the processing device 100 and the previous and next processes, the fixed slide rail 21 can be a linear slide rail or a curved slide rail.

[0087] The fixed slide rail 21 extends along the first direction, that is, the length direction of the fixed slide rail 21 is parallel to the first direction. This arrangement allows the lifting device 30 to move along the first direction on the fixed slide rail 21, so as to drive the upper body 300 to move along the first direction.

[0088] The floating slide rail 22 refers to the part of the slide rail structure 20 that can move relative to the fixed slide rail 21. The floating slide rail 22 is located on one side of the fixed slide rail 21 along the first direction. That is, the floating slide rail 22 can dock with the fixed slide rail 21 so that the lifting device 30 can move from the fixed slide rail 21 to the floating slide rail 22. The floating slide rail 22 can also move relative to the fixed slide rail 21. When the lifting device 30 moves to the floating slide rail 22, the floating slide rail 22 can drive the lifting device 30 to move. The floating slide rail 22 can be driven by a crane, cylinder or other structure to achieve movement. The floating slide rail 22 can also be supported by a movable bracket, trolley or other structure and its position can be manually controlled by the operator. Alternatively, a guide alignment structure corresponding to the lifting device 30 and the upper body 300 can be set on the lifting structure 10 and the chassis 200 to adjust the position of the floating slide rail 22.

[0089] The length direction of the floating slide rail 22 is parallel to the first direction, so that the lifting device 30 can move along the first direction on the floating slide rail 22, and also so that the lifting device 30 can move from the fixed slide rail 21 to the floating slide rail 22 along the first direction.

[0090] The floating slide rail 22 can move at least along the second direction, that is, the floating slide rail 22 can move only along the second direction, or it can move in other directions other than the second direction. In other words, the floating slide rail 22 can have only one direction of movement, or it can have two or more different directions of movement. The second direction is set at an angle to the first direction. The second direction can be perpendicular to the first direction, or it can be set at other angles to the first direction.

[0091] Because the floating slide rail 22 can move along the second direction, the lifting device 30 can move along the second direction with the floating slide rail 22. Also, because the lifting device 30 can move along the first direction on the floating slide rail 22, the lifting device 30 has at least two different directions. After the lifting device 30 moves the upper body 300 to above the lifting structure 10, the lifting device 30 can adjust its relative position with the lifting structure 10 in different directions, and thereby adjust the relative position between the upper body 300 and the chassis 200 to reduce the misalignment error between the upper body 300 and the chassis 200, so that the chassis 200 can better fit with the upper body 300.

[0092] The number of fixed slide rails 21 can be one, two or more.

[0093] When there is only one fixed slide rail 21, the fixed slide rail 21 can be located on the side of the floating slide rail 22 facing the previous process. In this case, the lifting device 30 can move from the previous process to the fixed slide rail 21, and then from the fixed slide rail 21 to the floating slide rail 22. At the same time, the lifting device 30 can also move directly from the floating slide rail 22 to the next process. When there is only one fixed slide rail 21, the fixed slide rail 21 can also be located on the side of the floating slide rail 22 facing the next process. In this case, the lifting device 30 can move directly from the previous process to the floating slide rail 22, and then from the floating slide rail 22 to the fixed slide rail 21. At the same time, the lifting device 30 can also move from the fixed slide rail 21 to the next process.

[0094] When there are two or more fixed slide rails 21, fixed slide rails 21 can be provided on both sides of the floating slide rail 22 along the first direction. At this time, the lifting device 30 can move from the previous process to a fixed slide rail 21, and then move from the fixed slide rail 21 to the floating slide rail 22. At the same time, the lifting device 30 can also move from the floating slide rail 22 to another fixed slide rail 21.

[0095] During the use of the processing device 100, the lifting device 30 can move onto the floating slide rail 22, at which point the lifting device 30 is located above the lifting structure 10. At this time, the lifting device 30 can stay on the floating slide rail 22, and the lifting device 30 can move along a first direction, while the floating slide rail 22 can move along a second direction, so that the upper body 300 can be aligned with the chassis 200 and meet the assembly accuracy requirements. After the upper body 300 and chassis 200 are aligned, the lifting structure 10 lifts the chassis 200 and brings it close to the upper body 300. Then, the workers assemble the chassis 200 and the upper body 300. After the chassis 200 and the upper body 300 are assembled, the lifting device 30 moves and carries the upper body 300 and chassis 200 away from the lifting structure 10 and move to the next process. After the chassis 200 and the upper body 300 are assembled, the lifting structure 10 is retracted so that the next chassis 200 can be transferred to the lifting structure 10.

[0096] In this embodiment, the slide rail structure 20 includes a fixed slide rail 21 and a floating slide rail 22, and the floating slide rail 22 is movable relative to the fixed slide rail 21. When the lifting device 30 moves onto the floating slide rail 22, this arrangement allows the lifting device 30 to move relative to the fixed slide rail 21, so that the upper vehicle body 300 can move relative to the chassis 200, thereby facilitating the adjustment of the position of the upper vehicle body 300 relative to the chassis 200. At the same time, this arrangement sets the corresponding structure for position adjustment at the lifting device 30 and the floating slide rail 22, separating the lifting and position adjustment of the chassis 200 and setting them in different positions, thereby alleviating the problem of the complexity of the lifting structure 10, reducing the strength requirements of the corresponding structure for position adjustment, reducing the cost of the device, and simplifying the complexity of the lifting structure 10, which facilitates improved efficiency.

[0097] refer to Figure 1 , Figure 2 In some embodiments, the slide rail structure 20 further includes a guide slide rail 23 extending in a second direction, the guide slide rail 23 being disposed on the side of the floating slide rail 22 away from the lifting structure 10; the floating slide rail 22 is movably connected to the guide slide rail 23.

[0098] The guide rail 23 refers to the structure in the rail structure 20 used to support the floating rail 22 and guide the movement of the floating rail 22. The number of guide rails 23 can be one, two or more; the cross-sectional shape of the guide rail 23 can be I-shaped, U-shaped or other shapes.

[0099] The guide rail 23 is located on the side of the floating rail 22 away from the lifting structure 10. For example, the guide rail 23 is located above the floating rail 22. Since the spreader 30 is used to drive the upper vehicle body 300 to move between the floating rail 22 and the lifting structure 10, placing the guide rail 23 on the side of the floating rail 22 away from the lifting structure 10 can reduce the interference of the guide rail 23 on the movement of the spreader 30.

[0100] The guide rail 23 extends along the second direction, that is, the length direction of the guide rail 23 is parallel to the second direction; the floating rail 22 is movably connected to the guide rail 23. The floating rail 22 can be movably connected to the guide rail 23 through a wheel set, sleeve, slider or other structure so that the floating rail 22 can move along the guide rail 23, thereby driving the lifting device 30 to move synchronously along the second direction.

[0101] This embodiment provides some specific structures of the slide rail structure 20, such that the slide rail structure 20 includes a guide slide rail 23 to guide the movement direction of the floating slide rail 22; under this setting, the lifting device 30 can move along the first direction, and the floating slide rail 22 can move along the second direction, so that the upper vehicle body 300 on the lifting device 30 can move in the first and second directions, thereby facilitating the adjustment of the position of the upper vehicle body 300 relative to the chassis 200.

[0102] refer to Figure 1 , Figure 2 In some embodiments, the number of guide rails 23 is at least two, and each guide rail 23 is spaced apart along a first direction.

[0103] The number of guide rails 23 is at least two, that is, the number of guide rails 23 can be two, three or more; since the guide rails 23 are used to guide the floating rails 22 to move in the second direction, and the length direction of the floating rails 22 is parallel to the first direction, the guide rails 23 are arranged at intervals along the first direction so that different positions of the floating rails 22 can be connected to the guide rails 23 respectively, so that each guide structure can guide the floating rails 22 to move in the second direction, and each guide rail 23 can provide support for the floating rails 22.

[0104] In this embodiment, the number of guide rails 23 is two, so that the floating rail 22 can slide more stably along the guide rail 23; at the same time, the guide rail 23 can provide more stable support for the lifting device 30 through the floating rail 22.

[0105] refer to Figure 1 , Figure 2 In some embodiments, the floating slide rail 22 and the fixed slide rail 21 are spaced apart.

[0106] The floating slide rail 22 and the fixed slide rail 21 are spaced apart, that is, there is a gap between the floating slide rail 22 and the fixed slide rail 21; for example, when the floating slide rail 22 is located on one side of the fixed slide rail 21 along the first direction, there is a gap between the floating slide rail 22 and the fixed slide rail 21.

[0107] Because the floating slide rail 22 can move relative to the fixed slide rail 21, this arrangement can reduce the friction and collision between the floating slide rail 22 and the fixed slide rail 21 during the movement, thereby reducing the risk of damage to the floating slide rail 22 and the fixed slide rail 21 and improving the stability of the processing device 100.

[0108] Understandably, since the floating slide rail 22 and the fixed slide rail 21 are spaced apart mainly to reduce collisions, the gap between the floating slide rail 22 and the fixed slide rail 21 can be small to reduce the interference of the gap on the movement of the lifting device 30 from the fixed slide rail 21 to the floating slide rail 22. For example, when the lifting device 30 moves on the floating slide rail 22 and the fixed slide rail 21 through the wheel structure, the distance between the fixed slide rail 21 and the floating slide rail 22 in the first direction should be smaller than the diameter of the wheel structure.

[0109] In this embodiment, the floating slide rail 22 and the fixed slide rail 21 are spaced apart to reduce the collision that may occur between the floating slide rail 22 and the fixed slide rail 21 during the movement.

[0110] refer to Figure 2 , Figure 3 In some embodiments, the processing apparatus 100 further includes a centering structure 40 for driving the floating slide rail 22 to an initial position; when the floating slide rail 22 is in the initial position, the lifting device 30 can move from the floating slide rail 22 to the fixed slide rail 21.

[0111] The initial position of the floating slide rail 22 refers to the position that the floating slide rail 22 can move to, which is also the position of the floating slide rail 22 on one side of the fixed slide rail 21 along the first direction. When the floating slide rail 22 is in the initial position, it can be aligned or approximately aligned with the fixed slide rail 21 so that the lifting device 30 can move from the fixed slide rail 21 to the floating slide rail 22, and also from the floating slide rail 22 to the fixed slide rail 21.

[0112] When the floating slide rail 22 is empty and the lifting device 30 has not yet transferred the upper body 300 from the previous process to the lifting structure 10, the floating slide rail 22 is in its initial position so that the lifting device 30 can move from the fixed slide rail 21 to the floating slide rail 22 in the first direction. When the lifting device 30 is on the floating slide rail 22 and the chassis 200 is assembled with the upper body 300, the floating slide rail 22 should return to its initial position so that the lifting device 30 can leave the floating slide rail 22 in the first direction so as to transfer the assembled upper body 300 and chassis 200 to the next process.

[0113] The centering structure 40 refers to the structure in the processing device 100 used to drive the floating slide rail 22 to move to the initial position. The centering structure 40 can drive the floating slide rail 22 to move along the second direction and return to the initial position. The centering structure can include a linear drive structure, such as a cylinder, hydraulic cylinder, electric cylinder, or other devices, or a structure such as a lead screw and slider with a motor, or a gear and rack with a motor. Depending on the direction of movement of the floating slide rail 22, the centering structure 40 can be located only on one side of the floating slide rail 22 along the second direction, or different parts of the centering structure 40 can be located on opposite sides of the floating slide rail 22 along the second direction.

[0114] When the spreader 30 is on the floating slide rail 22 and the chassis 200 is assembled with the upper body 300, the centering structure 40 can drive the floating slide rail 22 to move and return to the initial position, so that the spreader 30 can leave the floating slide rail 22, and also facilitate the next spreader 30 to move onto the floating slide rail 22.

[0115] In this embodiment, a centering structure 40 is provided so that the floating slide rail 22 can return to its initial position, so that the lifting device 30 can carry the assembled chassis 200 and upper body 300 to the next process, and also facilitate the next lifting device 30 to drive the upper body 300 to the floating slide rail 22.

[0116] refer to Figure 2 , Figure 3 In some embodiments, the centering structure 40 includes at least two centering components 41, which are disposed on both sides of the floating slide rail 22 along the second direction. The centering components 41 are configured to drive the floating slide rail 22 to move along the second direction to an initial position.

[0117] The centering component 41 refers to the structure in the centering structure 40 used to drive the floating slide rail 22 to move. The centering component 41 can push the floating slide rail 22 to move closer to the initial position along the second direction so that the floating slide rail 22 returns to the initial position. The centering component 41 may include a linear drive structure, such as a cylinder, hydraulic cylinder, electric cylinder, or other devices, or a structure such as a lead screw and slider with a motor, or a gear and rack with a motor.

[0118] There are at least two centering components 41, that is, the number of centering components 41 can be two, three or more; at least two centering components 41 are arranged on both sides of the floating slide rail 22 along the second direction, that is, at least one centering component 41 is provided on either side of the centering slide rail along the second direction, so that when the floating slide rail 22 moves along the second direction to either side, the centering component 41 can drive the floating slide rail 22 back to the initial position.

[0119] For example, the centering structure 40 includes four centering components 41, which are respectively located on opposite sides of the floating slide rail 22 along the second direction; two centering components 41 located on the same side of the floating slide rail 22 are spaced apart to drive the floating slide rail 22 to different positions.

[0120] This embodiment provides some specific structures of the centering structure 40. Centering components 41 are provided on both sides of the floating slide rail 22. With this configuration, when the floating slide rail 22 moves along the guide slide rail 23 to either side, the corresponding centering component 41 can drive the floating slide rail 22 back to the initial position.

[0121] refer to Figure 2 , Figure 3 In some embodiments of the centering structure 40 that include a centering component 41, the centering component 41 includes a first drive member 411 and a pusher member 412 connected to the first drive member 411. The first drive member 411 is used to drive the pusher member 412 to move in a second direction. The pusher member 412 includes a base 4121 and a pusher wheel 4122 rotatably connected to the base 4121. The base 4121 is connected to the first drive member 411. The axis of rotation of the pusher wheel 4122 is perpendicular to the first direction and the second direction. The pusher wheel 4122 is used to abut against the floating slide rail 22.

[0122] The pusher 412 refers to the structure in the centering assembly 41 used to push the floating slide rail 22 to move. The pusher 412 can move in the second direction to support the floating slide rail 22 and push the floating slide rail 22 to move in the second direction.

[0123] The first driving component 411 refers to the structure in the centering assembly 41 used to drive the pusher 412 to move. The first driving component 411 may include devices such as cylinders, hydraulic cylinders, and electric cylinders, or it may include structures such as lead screw and slider with motor, gear and rack with motor, etc. The first driving component 411 is fixed relative to the fixed slide rail 21. The first driving component 411 can be fixed to the fixed slide rail 21, the ground, the wall, or other positions by brackets or other structures. The first driving component 411 can drive the pusher 412 to move in the second direction and abut against the floating slide rail 22 to push the floating slide rail 22 to move. The first driving component 411 can also drive the pusher 412 to move in the second direction and disengage from the floating slide rail 22 to reduce the interference of the pusher 412 on the movement of the floating slide rail 22.

[0124] The base 4121 refers to the structure in the pusher 412 that provides a mounting base for the pusher wheel 4122 or other structures. The base 4121 is also connected to the first drive member 411 so that the first drive member 411 can drive the base 4121 to move in the second direction. The base 4121 can be a frame structure, a box structure, a plate structure or other shaped structure. The shape of the base 4121 can be square, round or other regular shape, or U-shaped, L-shaped or other irregular shape. The material of the base 4121 can include metal, plastic or other materials.

[0125] The push wheel 4122 refers to the structure in the pusher 412 used to support the floating slide rail 22. The push wheel 4122 is also a wheel structure that can rotate relative to the base 4121. The push wheel 4122 is rotatably connected to the base 4121. The axis of the push wheel 4122 is perpendicular to the first direction and the second direction, so that the push wheel 4122 can move along the second direction and the floating slide rail 22 can move. The number of push wheels 4122 can be one, two or more. The material of the push wheel 4122 can include metal, plastic or other materials.

[0126] In addition to pushing the floating slide rail 22 back to its initial position, the centering component 41 can also keep the floating slide rail 22 in its initial position. The two second driving members 512 on both sides of the floating slide rail 22 along the second direction drive the corresponding pushing members 412 to move towards the direction closer to the initial position, so as to abut against the opposite sides of the floating slide rail 22 along the second direction at the initial position, thereby achieving the effect of clamping and fixing the floating slide rail 22 and fixing the floating slide rail 22 in the initial position.

[0127] Understandably, since the floating slide rail 22 is movably connected to the guide slide rail 23, the floating slide rail 22 may have a short distance of movement in the first direction due to the influence of assembly accuracy. Accordingly, the structure that makes the pusher 412 contact the floating slide rail 22 is a wheel structure. When the floating slide rail 22 has displacement in the first direction, this setting can reduce frictional damage between the pusher 412 and the floating slide rail 22.

[0128] This embodiment provides a specific structure for the centering component 41, which includes a first driving member 411 and a pushing member 412, so that the first driving member 411 can drive the pushing member 412 to move, and push the floating slide rail 22 back to its initial position through the pushing member 412; the pushing member 412 includes a base 4121 and a pushing wheel 4122, so that the pushing member 412 can not only push the floating slide rail 22 to reset, but also reduce the friction between the pushing member 412 and the floating slide rail 22, thereby reducing the damage between the pushing member 412 and the floating slide rail 22.

[0129] refer to Figure 2 ,Figure 3 In some embodiments, a force-receiving member 221 is connected to the floating slide rail 22, and the centering component 41 is configured to push the force-receiving member 221 to move in a second direction.

[0130] The load-bearing component 221 refers to the structure on the floating slide rail 22 that abuts against the centering structure 40. The load-bearing component 221 can be a plate structure, a block structure, a frame structure, or other structures. The shape of the load-bearing component 221 can be circular, square, or other shapes. The load-bearing component 221 is connected to the floating slide rail 22 by welding, bonding, screwing, or other means. The load-bearing component 221 can also be integrally formed with the floating slide rail 22. The material of the load-bearing component 221 can include metal, plastic, or other materials. The material of the load-bearing component 221 can be the same as or different from the material of the floating slide rail 22.

[0131] Depending on the number of centering components 41, the number of force-bearing components 221 can be one, two, or more; when the number of force-bearing components 221 is two or more, each force-bearing component 221 can be arranged along the first direction.

[0132] For example, the force-bearing component 221 can be connected to the side of the floating slide rail 22 away from the lifting structure 10. Since the spreader 30 drives the upper vehicle body 300 to move between the floating slide rail 22 and the lifting structure 10, placing the force-bearing component 221 on the side of the floating slide rail 22 away from the lifting structure 10 can reduce the interference of the force-bearing component 221 on the movement of the spreader 30. Since the force-bearing component 221 is used to abut against the centering structure 40, the centering structure 40 should also be set in a corresponding manner to the force-bearing component 221. That is, the centering structure 40 is also located on the side of the floating slide rail 22 away from the lifting structure 10 in the height direction, which can further reduce the interference of the centering structure 40 on the movement of the spreader 30.

[0133] For example, during the process of the centering structure 40 driving the floating slide rail 22 back to its initial position, the centering component 41 on the side closer to the floating slide rail 22 moves, and the corresponding first driving member 411 drives the pushing member 412 to move towards the force-receiving member 221 and abut against the force-receiving member 221. Then the pushing member 412 pushes the force-receiving member 221 to move, thereby driving the floating slide rail 22 to move synchronously until the floating slide rail 22 returns to its initial position.

[0134] In this embodiment, a force-bearing component 221 is provided on the floating slide rail 22 so that the centering component 41 can drive the floating slide rail 22 to move by pushing the force-bearing component 221, thereby reducing the interference of the centering component 41 on the movement of the lifting device 30 on the floating slide rail 22.

[0135] refer to Figure 1 , Figure 2In some embodiments, there are two fixed slide rails 21, and the two fixed slide rails 21 are respectively located on opposite sides of the floating slide rail 22 along the first direction.

[0136] There are two fixed slide rails 21, which are respectively located on opposite sides of the floating slide rail 22 along the first direction. That is, the two fixed slide rails 21 are respectively located on the side of the floating slide rail 22 facing the previous process and the side facing the next process.

[0137] With the floating slide rail 22 in its initial position, the lifting device 30 can carry the upper body 300 from the previous process to a fixed slide rail 21, and then carry the upper body 300 from the fixed slide rail 21 to the floating slide rail 22; the lifting device 30 can also carry the assembled upper body 300 and chassis 200 from the floating slide rail 22 to another fixed slide rail 21, and carry the assembled upper body 300 and chassis 200 through the fixed slide rail 21 to the next process.

[0138] In this embodiment, the number of fixed slide rails 21 is two, so that the lifting device 30 of the previous process and the lifting device 30 that will move to the next process can move on different fixed slide rails 21, thereby reducing mutual interference and improving efficiency.

[0139] refer to Figure 2 , Figures 4 to 6 In some embodiments, the processing apparatus 100 further includes a positioning structure 50; the positioning structure 50 is configured to move relative to the lifting structure 10 to fix the relative position of the lifting device 30 and the lifting structure 10, and / or fix the relative position of the upper vehicle body 300 and the chassis 200.

[0140] The positioning structure 50 can refer to the structure in the processing device 100 used to fix the relative position of the lifting device 30 and the lifting structure 10. The positioning structure 50 can fix the lifting device 30 in the first assembly position above the lifting structure 10. When the lifting device 30 is in the first assembly position, the chassis 200 can be assembled with the upper body 300, and the assembly accuracy can meet the requirements without large errors or misalignments.

[0141] The positioning structure 50 can also refer to the structure in the processing device 100 used for the relative position of the upper body 300 and the chassis 200. The positioning structure 50 can also fix the upper body 300 in the second assembly position above the chassis 200. When the upper body 300 is in the second assembly position, the chassis 200 can be assembled with the upper body 300, and the assembly accuracy can meet the requirements without large errors or misalignments.

[0142] Depending on the specific function of the positioning structure 50, the positioning structure 50 may be used only to fix the lifting device 30 or the upper vehicle body 300, or it may be used to fix the lifting device 30 in part and the upper vehicle body 300 in another part, so that the lifting device 30 and the upper vehicle body 300 can be fixed by different parts of the positioning structure 50 respectively.

[0143] The positioning structure 50 may include a limiting post, a baffle, a locking body, or other structures. For example, the positioning structure 50 may include a limiting post, allowing the lifting device 30 to move in the direction of the limiting post. When the lifting device 30 abuts against or cooperates with the limiting post, the lifting device 30 is in a first assembly position. For example, the positioning structure 50 may also include a baffle, allowing the lifting device 30 to move in the direction of the limiting post. When the lifting device 30 abuts against the baffle, the lifting device 30 is in a first assembly position. For example, the positioning structure 50 may also include a locking body, allowing the lifting device 30 to move in the direction of the limiting post. When a part of the upper vehicle body 300 is locked into the locking body, the upper vehicle body 300 is in a second assembly position. It is understood that the positioning structure 50 may also include other structures to fix the lifting device 30 and / or the upper vehicle body 300, and is not limited to the above-mentioned types.

[0144] Depending on how the positioning structure 50 fixes the lifting device 30 and / or the upper vehicle body 300, the positioning structure 50 can be located on one side of the lifting structure 10, or on one or more sides of the lifting structure 10.

[0145] After the lifting device 30 carries the upper body 300 onto the floating slide rail 22, the positions of the lifting device 30 and the floating slide rail 22 can be adjusted, and the positions of the lifting device 30 and / or the upper body 300 relative to the lifting structure 10 and / or the chassis 200 are fixed by the fixing structure. After the positions of the lifting device 30 and / or the upper body 300 are fixed, the lifting structure 10 lifts the chassis 200, and the workers assemble the chassis 200 onto the upper body 300. Afterward, the fixing structure releases the fixing of the lifting device 30 and / or the upper body 300, the floating slide rail 22 returns to its initial position, and the lifting device 30 carries the assembled upper body 300 and chassis 200 away from the floating slide rail 22, thus completing one assembly process of the chassis 200 and the upper body 300.

[0146] In this embodiment, a positioning structure 50 is provided to adjust the relative positions of the straightening hoist 30 and the lifting structure 10, and to adjust the relative positions of the straightening chassis 200 and the upper body 300, so that the splicing accuracy of the chassis 200 and the upper body 300 can meet the requirements.

[0147] refer to Figure 2 , Figure 4In some embodiments, the lifting device 30 includes a lifting device body 31, on which a first positioning hole 311 is provided; the positioning structure 50 includes a first positioning component 51, which includes a first positioning member 511, which is configured to be movable relative to the lifting structure 10 to insert into or retract from the first positioning hole 311.

[0148] The main body 31 of the lifting device refers to the structure in the lifting device 30 used to support or lift the vehicle body 300. The main body 31 of the lifting device is used to support or lift the vehicle body 300. The main body 31 of the lifting device is also used to move along the fixed slide rail 21 or the floating slide rail 22 to carry the vehicle body 300 to the top of the lifting structure 10.

[0149] For example, the lifting body 31 may include a base and a boom. The base is movably connected to a fixed slide rail 21 or a floating slide rail 22, and the boom is swayably connected to a base plate. Part of the boom can swing from the upper body 300 to the lower body to support the upper body 300 and drive the upper body 300 to move.

[0150] The first positioning hole 311 refers to the structure on the lifting body 31 used to cooperate with the first positioning component 51. The first positioning hole 311 can be a through hole or a blind hole. The first positioning hole 311 can be a straight hole, a stepped hole, a conical hole or other hole structure. The first positioning hole 311 can be a round hole, a square hole or other hole structure. The number of first positioning holes 311 can be one, two or more. The first positioning hole 311 can be provided on the side of the lifting body 31 facing the lifting structure 10 or on other sides. For example, the first positioning hole 311 is provided on the side of the boom of the lifting body 31 facing the lifting structure 10.

[0151] The first positioning component 51 refers to the structure in the positioning structure 50 used to fix the relative position of the lifting device 30 and the lifting structure 10. The first positioning component 51 can fix the lifting device 30 in the first assembly position so that the chassis 200 and the upper body 300 can be assembled, and the assembly accuracy can meet the requirements without large errors or misalignments.

[0152] The number of first positioning components 51 can be one, two or more; depending on the specific structure of the first positioning component 51, the first positioning component 51 can be located on one side of the lifting structure 10, or on one or more sides of the lifting structure 10.

[0153] The first positioning element 511 refers to the structure in the first positioning assembly 51 that is used to cooperate with the first positioning hole 311. The first positioning element 511 can be a cylindrical structure, or a prism-shaped structure, a conical structure, a pyramidal structure, or other shapes. The first positioning assembly 51 can include one first positioning element 511, or it can include two or more first positioning elements 511. The material of the first positioning element 511 can include metal, plastic, or other materials.

[0154] The first positioning member 511 can move relative to the lifting structure 10 to insert into or retract from the first positioning hole 311. The first positioning member 511 can be driven by a structure such as a cylinder or hydraulic cylinder to insert into or retract from the first positioning hole 311. The first positioning member 511 can also be manually operated to insert into or retract from the first positioning hole 311. When the lifting device 30 is in the first assembly position, the first positioning member 511 can insert into the first positioning hole 311. At this time, the lifting device 30 is difficult to move relative to the lifting structure 10, and the positions of the lifting device 30 and the lifting structure 10 are relatively fixed. The first positioning member 511 can also retract from the first positioning hole 311 so that the floating slide rail 22 can return to the initial position.

[0155] This embodiment provides some specific structures of the positioning structure 50, such that the positioning structure 50 includes a first positioning component 51, so as to adjust the relative position between the lifting device 30 and the lifting structure 10 through the first positioning component 51, so that the lifting device 30 can be directly facing the lifting structure 10, thereby facilitating the reduction of the positional error between the chassis 200 and the upper body 300.

[0156] refer to Figure 2 , Figure 4 , Figure 5 In some embodiments, the first positioning member 511 includes a first fixing part 5111 and a first guide part 5112 connected to the first fixing part 5111. The first guide part 5112 is disposed on the side of the first fixing part 5111 facing the lifting device 30. In the direction of movement of the first positioning member 511, the first guide part 5112 is gradually reduced from the first fixing part 5111 toward the lifting device 30.

[0157] The first fixing part 5111 refers to the part of the first positioning member 511 that provides a fixing base for the first guide part 5112. The first fixing part 5111 can be a cylindrical structure, or a prism-shaped structure, a frustum-shaped structure, a frustum-shaped structure or other structures.

[0158] The first guide portion 5112 refers to the structure in the first positioning member 511 into which the first positioning hole 311 is inserted first. The first guide portion 5112 is located on the side of the first fixing portion 5111 facing the lifting device 30. The first guide portion 5112 can be connected to the first fixing portion 5111 by welding, bonding or other means. The first guide portion 5112 can also be integrally formed with the first fixing portion 5111.

[0159] The first guide portion 5112 can both enter the first positioning hole 311 to restrict the movement of the lifting device 30 and correct the position of the lifting device 30 relative to the lifting structure 10. The first guide portion 5112 has a structure that tapers towards the lifting device 30, that is, the end of the first guide portion 5112 connected to the first fixing portion 5111 has a larger diameter, while the end of the first guide portion 5112 facing the lifting device 30 has a smaller diameter, thereby making the peripheral surface of the first guide portion 5112 an inclined surface. When the lifting device 30 is not aligned with the lifting structure 10 and the lifting device 30 is not in the first assembly position, during the process of the first guide part 5112 being inserted into the first positioning hole 311, the peripheral side of the first guide part 5112 can first contact the edge of the first positioning hole 311. As the first guide part 5112 is gradually inserted into the first positioning hole 311, the lifting device 30 moves along the inclined surface of the first guide part 5112. After the first guide part 5112 is fully inserted into the first positioning hole 311, the lifting device 30 moves to the first assembly position.

[0160] Understandably, even when the position of the spreader 30 relative to the lifting structure 10 is offset and the spreader 30 is not in the first assembly position, the positional offset of the spreader 30 relative to the lifting structure 10 is also small, that is, the first guide part 5112 can complete the correction and adjustment of the position of the spreader 30.

[0161] After the first guide portion 5112 is inserted into the first positioning hole 311, the first fixing portion 5111 may be partially inserted into the first positioning hole 311 or may not be inserted into the first positioning hole 311 at all.

[0162] This embodiment provides some specific structures of the first positioning member 511, such that the first positioning member 511 includes a first guide portion 5112, and the first guide portion 5112 is a tapered structure. During the process of inserting the first guide portion 5112 into the first positioning hole 311, the first guide portion 5112 can guide and adjust the position of the lifting device 30 so that the lifting device 30 can be directly aligned with the lifting structure 10, thereby facilitating the reduction of positional errors between the chassis 200 and the upper body 300.

[0163] refer to Figure 2 , Figure 4In some embodiments, the first positioning component 51 further includes a second driving member 512, which is connected to the end of the first positioning member 511 away from the lifting device 30. The second driving member 512 is used to drive the first positioning member 511 to insert into or exit the first positioning hole 311.

[0164] The second driving component 512 refers to the structure in the first positioning assembly 51 used to drive the first positioning component 511 to insert into or exit the first positioning hole 311; one end of the second driving component 512 is connected to the first positioning component 511 to drive the first positioning component 511 to move; the second driving component 512 can be connected to the first positioning component 511 by welding, bonding, screwing, snapping or other means; the second driving component 512 may include devices such as cylinders, hydraulic cylinders, electric cylinders, etc., or may include structures such as lead screw and slider with motor, gear and rack with motor, etc.

[0165] After the lifting device 30 carries the upper body 300 onto the floating slide rail 22, the second drive member 512 drives the first positioning member 511 to insert into the first positioning hole 311. During this process, the first guide portion 5112 of the first positioning member 511 guides the lifting device 30 to move so that the lifting device 30 is in the first assembly position. After the first guide portion 5112 is fully inserted into the first positioning hole 311, the lifting device 30 is in the first assembly position. Then, the lifting structure 10 lifts the chassis 200, and the workers assemble the chassis 200 onto the upper body 300. After that, the second drive member 512 drives the first positioning member 511 to exit the first positioning hole 311. After that, the floating slide rail 22 returns to the initial position, and the lifting device 30 carries the assembled upper body 300 and chassis 200 away from the floating slide rail 22.

[0166] This embodiment provides some specific structures of the first positioning component 51 and sets a second driving member 512 to drive the first positioning component 511 to insert or withdraw from the first positioning hole 311, thereby facilitating the control of the movement state of the first positioning component 511; at the same time, the second driving member 512 can also provide sufficient power so that the first positioning component 511 can better adjust the relative position of the straightening hanger 30 and the lifting structure 10.

[0167] refer to Figure 2 In some embodiments, there are two first positioning components 51, and the two first positioning components 51 are disposed on opposite sides of the lifting structure 10 along the second direction; there are two first positioning holes 311, and the two first positioning holes 311 correspond to the two first positioning components 51 respectively.

[0168] There are two first positioning components 51, and corresponding to the first positioning components 51, there are also two first positioning holes 311. The two first positioning components 51 are respectively located on opposite sides of the lifting structure 10 along the second direction, and the corresponding first positioning holes 311 are also located on opposite sides of the lifting device 30 along the second direction, so that the first positioning members 511 of the two first positioning components 51 can be inserted into the corresponding first positioning holes 311 respectively.

[0169] Two first positioning components 51 are respectively located on opposite sides of the lifting structure 10 along the second direction, so that the two first positioning components 51 can better fix the position of the lifting device 30. Under the fixing action of the two first positioning components 51, the lifting device 30 is difficult to move, thereby fixing the lifting device 30 more stably in the first assembly position.

[0170] In this embodiment, the number of first positioning components 51 is two, so that the lifting device 30 can be subjected to force more evenly, and at the same time the load on a single first positioning component 51 can be reduced.

[0171] refer to Figure 2 , Figure 6 In some embodiments, the upper body 300 is provided with a second positioning hole 310; the positioning structure 50 includes a second positioning member 52, which is connected to the chassis 200 and is configured to move synchronously with the lifting structure 10 to insert into the second positioning hole 310.

[0172] The second positioning hole 310 refers to the structure on the upper body 300 used to cooperate with the second positioning member 52. The second positioning hole 310 can be a through hole or a blind hole. The second positioning hole 310 can be a straight hole, a stepped hole, a tapered hole or other hole structure. The second positioning hole 310 can be a round hole, a square hole or other hole structure. The number of second positioning holes 310 can be one, two or more. The second positioning hole 310 can be provided on the side of the upper body 300 facing the lifting structure 10.

[0173] The second positioning element 52 refers to the structure in the positioning structure 50 that is used to cooperate with the second positioning hole 310. The second positioning element 52 can be a cylindrical structure, or a prism-shaped structure, a conical structure, a pyramidal structure, or other shapes. The second positioning assembly can include one second positioning element 52, or two or more second positioning elements 52. The material of the second positioning element 52 can include metal, plastic, or other materials.

[0174] The second positioning component 52 is connected to the chassis 200. The second positioning component 52 can be connected to the chassis 200 by welding, bonding, screwing, snapping, or other means. During the process of the lifting structure 10 lifting the chassis 200, the second positioning component 52 can lift the chassis 200 synchronously to insert into the second positioning hole 310. When the upper body 300 is in the second assembly position, the second positioning component 52 can be inserted into the second positioning hole 310. At this time, the chassis 200 and the upper body 300 can be assembled and it is difficult for them to shift or tilt, and the assembly accuracy can meet the requirements. When the second positioning hole 310 cannot be inserted, it is difficult for the chassis 200 and the upper body 300 to be assembled, and the assembly accuracy cannot meet the requirements.

[0175] This embodiment provides some specific structures of the positioning structure 50, such that the positioning structure 50 includes a second positioning member 52, so as to adjust the relative position between the chassis 200 and the upper body 300 through the second positioning member 52, so that the chassis 200 can be directly aligned with the upper body 300, thereby facilitating the reduction of positional error between the chassis 200 and the upper body 300.

[0176] refer to Figure 2 , Figure 6 In some embodiments, the second positioning member 52 includes a second fixing part 521 and a second guide part 522 connected to the second fixing part 521. The second guide part 522 is disposed on the side of the second fixing part 521 facing the lifting device 30. In the movement direction of the second positioning member 52, the second guide part 522 is gradually reduced from the second fixing part 521 toward the lifting device 30.

[0177] The second fixing part 521 refers to the part of the second positioning member 52 that provides a fixing base for the second guide part 522. The second fixing part 521 can be a cylindrical structure, or a prism-shaped structure, a frustum-shaped structure, a truncated cone-shaped structure, or other structures.

[0178] The second guide portion 522 refers to the structure in the second positioning member 52 into which the second positioning hole 310 is first inserted. The second guide portion 522 is located on the side of the second fixing portion 521 facing the upper vehicle body 300. The second guide portion 522 can be connected to the second fixing portion 521 by welding, bonding or other means. The second guide portion 522 can also be integrally formed with the second fixing portion 521.

[0179] The second guide part 522 can enter the second positioning hole 310 to restrict the movement of the upper body 300. The second guide part 522 can also correct the position of the upper body 300 relative to the chassis 200. During the lifting and transfer process, the upper body 300 has a certain amount of room for movement on the lifting device 30 due to the influence of the structure of the lifting device 30. That is, the position of each upper body 300 transported by the lifting device 30 to the top of the lifting structure 10 may be offset to a certain extent, and the position of each upper body 300 transported by the lifting device 30 to the top of the lifting structure 10 is uncertain. Therefore, it is necessary to correct and determine the position of the upper body 300 through the second positioning part 52 so that the upper body 300 can be located in the determined second assembly position.

[0180] The second guide portion 522 has a structure that tapers towards the lifting device 30. That is, the end of the second guide portion 522 connected to the second fixing portion 521 has a larger diameter, while the end of the second guide portion 522 facing the lifting device 30 has a smaller diameter, thus making the peripheral side surface of the second guide portion 522 an inclined surface. When the upper body 300 and the chassis 200 are not aligned and the upper body 300 is not in the second assembly position, during the process of the second guide portion 522 being inserted into the second positioning hole 310, the peripheral side surface of the second guide portion 522 can first contact the edge of the second positioning hole 310. As the second guide portion 522 is gradually inserted into the second positioning hole 310, the lifting device 30 moves along the inclined surface of the second guide portion 522. After the second guide portion 522 is fully inserted into the second positioning hole 310, the lifting device 30 moves to the second assembly position.

[0181] Understandably, when there is a positional offset between the upper body 300 and the chassis 200 and the upper body 300 is not in the second assembly position, the positional offset between the upper body 300 and the chassis 200 is also small, that is, the second guide part 522 can complete the correction and adjustment of the position of the upper body 300.

[0182] After the second guide portion 522 is inserted into the second positioning hole 310, the second fixing portion 521 may be partially inserted into the second positioning hole 310 or may not be inserted into the second positioning hole 310 at all.

[0183] It is understood that the processing device 100 may include only the first positioning component 51 or the second positioning component 52, or it may include both the first positioning component 51 and the second positioning component 52. For example, the processing device 100 includes the first positioning component 51 and the second positioning component 52. In this case, after the lifting device 30 moves to the floating slide rail 22, the first positioning component 51 first adjusts and fixes the position of the lifting device 30 so that the lifting device 30 is in the first assembly position. Then the second positioning component 52 adjusts the position of the upper body 300 so that the upper body 300 is in the second assembly position. During the adjustment process of the second positioning component 52, the upper body 300 can be displaced relative to the lifting device 30.

[0184] This embodiment provides some specific structures of the second positioning member 52, such that the second positioning member 52 includes a second guide portion 522, and the second guide portion 522 has a tapered structure. During the process of inserting the second guide portion 522 into the second positioning hole 310, the second guide portion 522 can guide and adjust the position of the upper body 300 so that the upper body 300 can be directly aligned with the chassis 200, thereby facilitating the reduction of positional errors between the chassis 200 and the upper body 300.

[0185] refer to Figure 1 In some embodiments, the processing apparatus 100 further includes a carrier 60 for supporting the chassis 200, and the carrier 60 is configured to move onto the lifting structure 10 for being lifted by the lifting structure 10.

[0186] The carrier 60 refers to the structure in the processing device 100 used to support and transport the chassis 200. The chassis 200 can be placed on the carrier 60 and supported and carried by the carrier 60, thereby driving the chassis 200 to move between various processing steps and processing equipment. The carrier 60 can be a trolley structure, a plate structure, a frame structure, or other structures. For example, the carrier 60 can be a skid, which is a carrying and transporting tool used in the vehicle production process to support and transport the chassis 200.

[0187] During the process of lifting the chassis 200 by the lifting structure 10, the lifting structure 10 lifts the carrier 60, and thereby lifts the chassis 200; after the chassis 200 is assembled with the upper body 300, the carrier 60 is idle. At this time, the carrier 60 leaves the lifting structure 10, and another carrier 60 carrying the chassis 200 moves onto the lifting structure 10.

[0188] In this embodiment, a support member 60 is provided, and the chassis 200 is supported by the support member 60 so as to move the chassis 200 from the previous process to the lifting structure 10.

[0189] In some embodiments, the upper body 300 is provided with a second positioning hole 310; the positioning structure 50 includes a second positioning member 52, which is connected to the carrier member 60 and is configured to move synchronously with the lifting structure 10 to insert into or retract from the second positioning hole 310.

[0190] The second positioning hole 310 refers to the structure on the upper body 300 that is used to cooperate with the second positioning member 52; the second positioning member 52 refers to the structure in the positioning structure 50 that is used to cooperate with the second positioning hole 310. The second positioning member 52 is provided on the carrier member 60 and can be connected to the carrier member 60 by welding, bonding, screwing or other means.

[0191] In this embodiment, the second positioning member 52 is disposed on the carrier member 60. At this time, the second positioning member 52 can pass through the chassis 200, and the second positioning member 52 can also be located on the periphery of the chassis 200. When the positions of the chassis 200 and the carrier member 60 are relatively fixed and difficult to shift, this arrangement can also fix the relative position of the upper body 300 and the chassis 200 through the second positioning member 52 and the second positioning hole 310, and correct the position of the upper body 300 to the second assembly position.

[0192] For example, the second positioning member 52 is provided on the carrier member 60 and passes through the chassis 200; during the process of the lifting structure 10 lifting the carrier member 60, the second positioning member 52 can be gradually inserted into the second positioning hole 310 and can correct the position of the upper body 300 in the process; after the chassis 200 is assembled with the upper body 300, the lifting structure 10 descends and drives the carrier member 60 to descend. At this time, the carrier member 60 is separated from the chassis 200, and the second positioning member 52 is also separated from the upper body 300 and the chassis 200.

[0193] In this embodiment, the second positioning member 52 is disposed on the carrier member 60 so as to adjust and correct the position between the chassis 200 and the upper body 300.

[0194] In some embodiments, the processing apparatus 100 further includes a drive structure for driving the lifting device 30 to move along the slide rail structure 20; the drive structure is disposed on the lifting device 30, or the drive structure is fixed relative to the fixed slide rail 21.

[0195] The drive structure refers to the structure in the processing device 100 used to drive the lifting device 30 to move relative to the fixed slide rail 21 and the floating slide rail 22. The drive structure may include a motor, a hydraulic pump or other drive devices or structures. The drive structure is fixed relative to the fixed slide rail 21, that is, the drive structure can be connected to the fixed slide rail 21, the ground, the wall or other structures through a bracket or other structure. In this case, the first processing device 100 may only have one drive structure. The drive structure may also be connected to the lifting device 30. In this case, each lifting device 30 may have one drive structure.

[0196] In this embodiment, a drive structure is provided to drive the lifting device 30 to move along the floating slide rail 22 and the fixed slide rail 21, so that the lifting device 30 can carry the upper body 300 to the top of the lifting structure 10, and also so that the lifting device 30 can carry the assembled upper body 300 to the next process.

[0197] In some embodiments, the processing apparatus 100 includes a lifting structure 10, a slide rail structure 20, a lifting device 30, a centering structure 40, and a positioning structure 50.

[0198] The slide rail structure 20 includes a fixed slide rail 21, a floating slide rail 22 and another fixed slide rail 21 arranged sequentially at intervals along the first direction X; the slide rail structure 20 also includes a guide slide rail 23, the length direction of the guide slide rail 23 is parallel to the second direction Y, and the floating slide rail 22 is slidably connected to the guide slide rail 23.

[0199] The centering structure 40 includes four centering components 41, which are respectively disposed on opposite sides of the floating slide rail 22 along the second direction, with two centering components 41 disposed on each side of the floating slide rail 22. Each centering component 41 includes a first driving member 411 and a pushing member 412 connected to the first driving member 411. The pushing member 412 includes a base 4121 connected to the first driving member 411 and a pushing wheel 4122 rotatably connected to the base 4121.

[0200] The positioning structure 50 includes a first positioning component 51 and a second positioning element 52. There are two first positioning components 51, which are respectively located on opposite sides of the lifting structure 10 along the second direction. The first positioning component 51 includes a second driving element 512 and a first positioning element 511 connected to the second driving element 512. The second positioning element 52 is connected to the chassis 200.

[0201] The lifting device 30 is provided with a first positioning hole 311, and the upper body 300 is provided with a second positioning hole 310.

[0202] During the use of the processing device 100, the lifting device 30 carries the vehicle body 300 from the fixed slide rail 21 along the first direction to the floating slide rail 22. At this time, the lifting device 30 is located above the lifting structure 10; at this time, the lifting device 30 stays on the floating slide rail 22.

[0203] Subsequently, the second driving member 512 drives the first positioning member 511 to insert into the first positioning hole 311, and in the process, corrects the position of the lifting device 30 to the first assembly position; the lifting device 30 can move along the first direction X on the floating slide rail 22, and the floating slide rail 22 can also move along the second direction Y on the guide slide rail 23, so that the lifting device 30 can move to the first assembly position; in this process, each first driving member 411 drives the corresponding pushing member 412 to be in a retracted state, and each pushing member 412 is far away from the floating slide rail 22 to reduce the interference of the movement of the floating slide rail 22.

[0204] Subsequently, the lifting structure 10 lifts the chassis 200. During this process, the second positioning member 52 is inserted into the second positioning hole 310 and the position of the upper body 300 is corrected to the first assembly position. The upper body 300 can move relative to the lifting device 30 during this process.

[0205] After that, the body 300 and chassis 200 were assembled.

[0206] Subsequently, the lifting structure 10 descends, and the first driving component 411 drives the first positioning component 511 to exit the first positioning hole 311.

[0207] Subsequently, the two centering components 41 close to the floating slide rail 22 are activated, and the corresponding first driving member 411 drives the corresponding pushing member 412 to move along the second direction to push the floating slide rail 22 to the initial position.

[0208] Afterwards, the spreader 30 moves and pulls the upper body 300 and chassis 200 away from the lifting structure 10 and move to the next process.

[0209] Secondly, embodiments of this application also provide a processing system, including the processing apparatus 100 provided in some embodiments of the first aspect. During the processing of a vehicle in the processing system, the position adjustment of the chassis 200 and the upper body 300 is achieved through the lifting device 30 and the floating slide rail 22, and the lifting of the chassis 200 is achieved through the lifting structure 10. This reduces the load on the position adjustment structure, improves the stability of the processing apparatus 100 and the entire processing system, and also increases processing efficiency.
