Description

Technical Field

[0001] This application relates to the field of device technology, specifically to a positioning device. Background Technology

[0002] During vehicle assembly, the A-pillar inner panel typically requires a positioning device to accurately position it for precise assembly. However, different vehicle models have different A-pillar inner panel structures, resulting in varying positioning positions. Therefore, a positioning device that can adapt to the positioning requirements of different vehicle models is necessary.

[0003] In existing technologies, to meet the needs of multi-model co-production, a windmill mechanism is typically used to switch positioning devices to achieve the positioning requirements of the A-pillar inner panel for different models. This involves setting multiple positioning components on a turntable, each component being adapted to the A-pillar inner panel of a specific model. By driving the turntable to rotate, the corresponding positioning component is rotated to the A-pillar inner panel, thus positioning the A-pillar inner panel.

[0004] However, in the existing technology, multiple positioning components need to be set on the turntable, which makes the structure of the positioning device more complex and increases the cost of the positioning device. Utility Model Content

[0005] The purpose of this application is to provide a positioning device to at least address the problem of how to reduce the cost of positioning devices.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: In a first aspect, a positioning device is provided for positioning the inner A-pillar panel of a vehicle. The positioning device includes a positioning component, a first driving component, and a second driving component. The positioning component engages with a positioning hole in the inner A-pillar panel. The first driving component is connected to the positioning component and drives the positioning component to move along a first direction, which is aligned with the length direction of the inner A-pillar panel. The second driving component is connected to the first driving component and drives the first driving component to move along a second direction, which is aligned with the thickness direction of the inner A-pillar panel.

[0007] Through the above technical solution, the positioning device provided in this application, by connecting the first driving component and the positioning component, allows the first driving component to drive the positioning component to move along a first direction, thereby adjusting the position of the positioning component in the first direction. By connecting the second driving component and the first driving component, the second driving component can drive the first driving component to move along a second direction. The first driving component and the positioning component are connected, thereby driving the positioning component to move along the second direction, thereby adjusting the position of the positioning component in the second direction. Thus, through the synergistic action of the first and second driving components, the positioning component can move in both the first and second directions to adjust its position, allowing it to mate with the positioning holes of the A-pillar inner panels of different vehicle models, achieving positioning of the A-pillar inner panels of different vehicle models. The positioning device of this application only requires one positioning component. By adjusting the position of the positioning component through the first and second driving components, the position of the positioning component can be aligned with the positioning holes of the A-pillar inner panel to achieve positioning of the A-pillar inner panels of different vehicle models, simplifying the structure of the positioning device and saving its cost.

[0008] Furthermore, the cooperation between the positioning components in the aforementioned positioning device and the positioning holes of the A-pillar inner panels of different vehicle models can simplify the structure of the positioning device and reduce the space occupied by the positioning components in the positioning device, thereby making the structure of the positioning device more compact. This facilitates the subsequent welding of the A-pillar inner panels and other parts of the vehicle body by the robot after positioning, avoiding interference between the welding trajectory of the positioning components and the robot, thus improving the welding quality and ensuring the assembly accuracy of the vehicle body.

[0009] In some embodiments, the second drive component includes a first power structure and a second power structure. The first power structure is connected to the first drive component and is used to drive the first drive component to move in a second direction. The second power structure is connected to the first power structure and is used to drive the first power structure to move in the second direction.

[0010] Through the above technical solution, by connecting the first power structure and the first drive component, and connecting the second power structure and the first power structure, a two-stage drive structure can be formed by the second drive component. Specifically, the second power structure can drive the first power structure to move along the second direction, and the first power structure can drive the first drive component to move along the second direction, further driving the positioning component to move along the second direction, so as to adjust the position of the positioning component in the second direction. In this way, through the setting of the two-stage drive structure, the second power structure can drive the positioning component to move quickly to the vicinity of the target position in the second direction and perform initial positioning (i.e., coarse positioning). After the positioning component moves to the vicinity of the target position in the second direction, the first power structure can drive the positioning component to move to the target position in the second direction and perform precise positioning, so as to balance the positioning accuracy and positioning efficiency of the positioning device.

[0011] In some embodiments, the first power structure includes a first support member, a power member, and a guide assembly. A first drive assembly is connected to the first support member, and the power member is connected to the second power structure, and the power member is also connected to the first support member, for driving the first support member to move in a second direction. The guide assembly is connected between the first support member and the second power structure, for guiding the first drive assembly in the second direction.

[0012] Through the above technical solution, by connecting the first drive component to the first support member, and the power component to the second power structure and connected to the first support member, the power output by the power component can drive the first support member to move along the second direction, further driving the first drive component to move along the second direction. The first drive component and the positioning component are connected, thereby driving the positioning component to move along the second direction. In this way, the first power structure can drive the positioning component to move to the target position in the second direction. This driving method has a simple structure, high transmission efficiency, and allows for flexible adjustment of the position of the positioning component in the second direction to achieve the matching of the positioning component with the positioning holes of the A-pillar inner panel of different vehicle models.

[0013] Furthermore, by connecting the first drive component to the first support member, the first support member can support the first drive component, thereby improving the stability of the first drive component moving in the second direction, further improving the stability of the positioning component moving in the second direction, and realizing high-precision positioning of the positioning component on the inner panel of the A-pillar.

[0014] Meanwhile, by connecting the guide component between the first support member and the second power structure, the guide component can guide the first support member so that the first support member moves along the second direction according to the preset trajectory of the guide component, thereby avoiding trajectory errors such as deviation of the first support member during movement, which would affect the positioning accuracy of the positioning component.

[0015] In some embodiments, the first power structure further includes a first protective member, the first protective member having a first protective space, and a guide component disposed within the first protective space.

[0016] Through the above technical solution, the first protective component provides a first protective space, and the guide component is located in the first protective space. The first protective component can protect the guide component to prevent dust, chips and oil and other contaminants from coming into contact with the guide component, thereby preventing contaminants from entering the interior of the guide component, causing wear or damage, and extending the service life of the guide component.

[0017] Furthermore, by providing a first protective space for a protective component and placing the guide component within the first protective space, the first protective space can provide a stable internal environment for the guide component, thereby ensuring the long-term motion accuracy and reliability of the guide component.

[0018] In some embodiments, the first support member is provided with a relief groove, which is recessed from the side surface of the first support member facing the second power structure away from the second power structure, and the relief groove penetrates the first support member along the second direction, with a portion of the first protective member disposed in the relief groove.

[0019] Through the above technical solution, by setting the clearance groove, part of the first protective member (i.e., the third protective plate) can be located in the clearance groove, so as to facilitate the connection between the first support member and the second component in the guide assembly, thereby avoiding interference between the first support member and the first protective member during the movement, which would affect the smoothness of the movement of the first support member.

[0020] Furthermore, by placing a portion of the first protective member within the clearance groove, the overall dimensions of the first protective member and the first support member in the first direction can be reduced, further reducing the dimensions of the first power structure in the first direction, and even further reducing the dimensions of the second drive assembly in the first direction, so as to make the structure of the second drive assembly more compact.

[0021] In some embodiments, the power component can drive the first support component to move between a first position and a second position. When the first support component is in the first position, the positioning component can engage with the positioning hole of the A-pillar inner panel for positioning. When the first support component is in the second position, the positioning component can separate from the A-pillar inner panel. The first power structure also includes a first limiting component and a second limiting component. Along the second direction, the first limiting component is located on one side of the first support component, and the second limiting component is located on the other side of the first support component. When the first support component is in the first position, both the first limiting component and the second limiting component are in contact with and limited by the first support component.

[0022] Through the above technical solution, along the second direction, by placing the first limiting member on one side of the first support member and the second limiting member on the other side of the first support member, when the first support member is in the first position, both the first limiting member and the second limiting member can contact and limit the first support member. That is, in the first position, the first limiting member and the second limiting member respectively limit the first support member from both sides of the first support member in the second direction, ensuring the stability of the first support member, thereby ensuring the stability of the first driving assembly and the positioning assembly, so that the positioning assembly remains stable when positioning with the inner panel of the A-pillar, and improving the positioning effect.

[0023] In some embodiments, at least one of the first limiting member and the second limiting member includes a driving part and a limiting part, the driving part being connected to the limiting part and used to drive the limiting part to move so that when the first support member is in a first position, the limiting part contacts and limits the first support member, and when the first support member is in a second position, the limiting part separates from the first support member.

[0024] With the above technical solution, when the first support member is in the first position, the driving unit drives the limiting part to move to contact the first support member, thereby limiting the contact of the first support member. When the first support member is in the second position, at least one of the first limiting part and the second limiting part releases the limiting part from the first support member, and the driving unit drives the limiting part to move to separate from the first support member. This limiting method has a simple structure, high positioning accuracy, and is easy to implement.

[0025] In some embodiments, the positioning component includes a first hook cylinder and a second hook cylinder arranged at intervals along the first direction, both of which are used to engage with positioning holes in the inner panel of the A-pillar.

[0026] Through the aforementioned technical solution, the unique "insertion-clamping" action mechanism of the first and second hook pin cylinders provides two key advantages. First, precise positioning ensures that both cylinders engage with the positioning holes in the A-pillar inner panel. Second, the first and second hook pin cylinders provide powerful active clamping, effectively resisting vibration and thermal deformation during subsequent dynamic processes such as welding, ensuring the A-pillar inner panel remains in its primary position. This provides a fundamental guarantee for achieving high-precision vehicle body manufacturing.

[0027] In some embodiments, the positioning assembly further includes a first fixing member, a second fixing member, and a first gasket. The first fixing member is connected to the first driving assembly, the second fixing assembly is connected to the first fixing member on the third-direction upward side, the third-direction being perpendicular to the first direction and perpendicular to the second direction, the first gasket being detachably connected between the first fixing member and the second fixing member, and the first hook cylinder being connected to the second fixing member.

[0028] Through the above technical solution, the first and second fixing components facilitate the connection between the first drive assembly and the first hook cylinder, enabling the disassembly and maintenance of the first hook cylinder. The first gasket, detachably connected between the first and second fixing components, allows adjustment of the dimensional error of the positioning holes of the first hook cylinder and the A-pillar inner panel in the third direction, ensuring precise alignment of the positioning holes in the third direction.

[0029] In some embodiments, the first hook cylinder is connected to one side of the second fixing member in the second direction, and the positioning assembly further includes a second gasket, which is detachably connected between the first hook cylinder and the second fixing member.

[0030] By using the above technical solution, the second gasket can be detachably connected between the first hook cylinder and the second fixing member, thereby adjusting the dimensional error of the positioning hole of the first hook cylinder and the inner plate of the A-pillar in the second direction, so as to ensure the precise alignment of the positioning hole of the first hook cylinder and the inner plate of the A-pillar in the second direction.

[0031] The beneficial effects of this application are: (1) The positioning device provided in this application connects a first driving component and a positioning component. The first driving component can drive the positioning component to move along a first direction to adjust the position of the positioning component in the first direction. By connecting a second driving component and a first driving component, the second driving component can drive the first driving component to move along a second direction. The first driving component and the positioning component are connected, thereby driving the positioning component to move along the second direction to adjust the position of the positioning component in the second direction. Thus, through the synergistic action of the first and second driving components, the positioning component can move in both the first and second directions to adjust its position, allowing it to mate with the positioning holes of the A-pillar inner panels of different vehicle models, thereby achieving the positioning of the A-pillar inner panels of different vehicle models. The positioning device of this application only requires one positioning component. By adjusting the position of the positioning component through the first and second driving components, the position of the positioning component can be aligned with the positioning holes of the A-pillar inner panel to achieve the positioning of the A-pillar inner panels of different vehicle models, simplifying the structure of the positioning device and saving its cost.

[0032] Furthermore, the cooperation between the positioning components in the aforementioned positioning device and the positioning holes of the A-pillar inner panels of different vehicle models can simplify the structure of the positioning device and reduce the space occupied by the positioning components in the positioning device, thereby making the structure of the positioning device more compact. This facilitates the subsequent welding of the A-pillar inner panels and other parts of the vehicle body by the robot after positioning, avoiding interference between the welding trajectory of the positioning components and the robot, thus improving the welding quality and ensuring the assembly accuracy of the vehicle body.

[0033] (2) By connecting the first power structure and the first drive component, and connecting the second power structure and the first power structure, the second drive component can form a two-stage drive structure. Specifically, the second power structure can drive the first power structure to move along the second direction, and the first power structure can drive the first drive component to move along the second direction, further driving the positioning component to move along the second direction, so as to adjust the position of the positioning component in the second direction. In this way, through the setting of the two-stage drive structure, the second power structure can drive the positioning component to move quickly to the vicinity of the target position in the second direction and perform initial positioning (i.e., coarse positioning). After the positioning component moves to the vicinity of the target position in the second direction, the first power structure can drive the positioning component to move to the target position in the second direction and perform precise positioning, so as to take into account both the positioning accuracy and positioning efficiency of the positioning device.

[0034] (3) By connecting the first drive assembly to the first support member, and the power component to the second power structure and connected to the first support member, the power output by the power component can drive the first support member to move in the second direction, further driving the first drive assembly to move in the second direction. The first drive assembly and the positioning assembly are connected, thereby driving the positioning assembly to move in the second direction. In this way, the first power structure can drive the positioning assembly to move to the target position in the second direction. This drive method has a simple structure, high transmission efficiency, and can flexibly adjust the position of the positioning assembly in the second direction to achieve the matching of the positioning assembly with the positioning holes of the A-pillar inner panel of different vehicle models.

[0035] Furthermore, by connecting the first drive component to the first support member, the first support member can support the first drive component, thereby improving the stability of the first drive component moving in the second direction, further improving the stability of the positioning component moving in the second direction, and realizing high-precision positioning of the positioning component on the inner panel of the A-pillar.

[0036] Meanwhile, by connecting the guide component between the first support member and the second power structure, the guide component can guide the first support member so that the first support member moves along the second direction according to the preset trajectory of the guide component, thereby avoiding trajectory errors such as deviation of the first support member during movement, which would affect the positioning accuracy of the positioning component.

[0037] (4) A first protective space is provided through the first protective component, and the guide component is located in the first protective space. The first protective component can protect the guide component to prevent dust, chips and oil stains from contacting the guide component, thereby preventing contaminants from entering the guide component and causing wear or damage, and extending the service life of the guide component.

[0038] (5) By setting the clearance groove, part of the first protective member (i.e. the third protective plate) can be located in the clearance groove to facilitate the connection between the first support member and the second component in the guide assembly, thereby avoiding interference between the first support member and the first protective member during the movement process and affecting the smoothness of the movement of the first support member.

[0039] Furthermore, by placing a portion of the first protective member within the clearance groove, the overall dimensions of the first protective member and the first support member in the first direction can be reduced, further reducing the dimensions of the first power structure in the first direction, and even further reducing the dimensions of the second drive assembly in the first direction, so as to make the structure of the second drive assembly more compact.

[0040] (6) Along the second direction, by placing the first limiting member on one side of the first support member and the second limiting member on the other side of the first support member, when the first support member is in the first position, both the first limiting member and the second limiting member can contact and limit the first support member. That is, when in the first position, the first limiting member and the second limiting member limit the first support member from both sides of the first support member in the second direction to ensure the stability of the first support member, thereby ensuring the stability of the first drive assembly and the positioning assembly, so that the positioning assembly remains stable when positioning with the inner panel of the A-pillar, and improving the positioning effect.

[0041] (7) When the first support member is in the first position, the driving unit drives the limiting part to move to contact the first support member, so as to limit the contact of the first support member. When the first support member is in the second position, at least one of the first limiting part and the second limiting part releases the limiting of the first support member, and the driving unit drives the limiting part to move to separate from the first support member. This limiting method has a simple structure, high positioning accuracy, and is easy to implement.

[0042] (8) Due to the unique "insertion-clamping" action mechanism of the first and second hook pin cylinders, on the one hand, precise positioning can be provided so that both the first and second hook pin cylinders can cooperate with the positioning holes of the A-pillar inner panel. On the other hand, the first and second hook pin cylinders can also provide strong active clamping, which can effectively resist vibration and thermal deformation in subsequent dynamic processes such as welding, ensuring that the A-pillar inner panel always remains in the first position, thus providing a fundamental guarantee for achieving high-precision body manufacturing.

[0043] (9) The first and second fixing parts facilitate the connection between the first drive assembly and the first hook cylinder, making it easier to disassemble and maintain the first hook cylinder. The first gasket, which is detachably connected between the first and second fixing parts, can adjust the dimensional error of the positioning holes of the first hook cylinder and the inner A-pillar panel in the third direction, so as to ensure the accurate alignment of the positioning holes of the first hook cylinder and the inner A-pillar panel in the third direction.

[0044] (10) By detachably connecting the second gasket between the first hook cylinder and the second fixing member, the dimensional error of the positioning hole of the first hook cylinder and the inner plate of the A-pillar in the second direction can be adjusted to ensure the accurate alignment of the positioning hole of the first hook cylinder and the inner plate of the A-pillar in the second direction.

[0047] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application are within the scope of protection of this application.

[0048] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0050] A vehicle may include an A-pillar assembly, which typically consists of an inner A-pillar panel and an outer A-pillar panel. The vehicle assembly process includes assembling the inner A-pillar panel, for example, by assembling it to the outer A-pillar panel. To ensure the assembly accuracy of the inner A-pillar panel, a positioning device is usually required. However, due to the different structures of different vehicle models, the positioning positions of the inner A-pillar panels vary, primarily reflected in the different heights of the positioning holes on the inner A-pillar panels across different vehicle models. Therefore, the positioning device needs to meet the positioning requirements of the inner A-pillar panels for different vehicle models.

[0051] Based on this, please refer to Figures 1 to 5 This application provides a positioning device 10 for positioning the inner A-pillar panel of a vehicle, so that a welding robot can weld the positioned inner A-pillar panel to other parts of the vehicle body (e.g., outer A-pillar panel, dashboard, windshield, etc.) to achieve vehicle body assembly.

[0052] In some embodiments, please continue reading Figure 1 The positioning device 10 may include a positioning component 1, a first driving component 2, and a second driving component 3. The positioning component 1 is used to mate with a positioning hole in the inner panel of the A-pillar. The first driving component 2 is connected to the positioning component 1 and is used to drive the positioning component 1 along a first direction (e.g., Figure 1The first direction (A) moves along the length direction of the inner A-pillar panel. The second drive assembly 3 is connected to the first drive assembly 2 and is used to drive the first drive assembly 2 along the second direction (e.g., ...). Figure 1 Move in direction B), and the second direction is consistent with the thickness direction of the inner plate of column A.

[0053] In this way, by connecting the first drive assembly 2 and the positioning assembly 1, the first drive assembly 2 can drive the positioning assembly 1 to move along a first direction to adjust its position in that direction. By connecting the second drive assembly 3 and the first drive assembly 2, the second drive assembly 3 can drive the first drive assembly 2 to move along a second direction. The first drive assembly 2 is connected to the positioning assembly 1, thus driving the positioning assembly 1 to move along the second direction to adjust its position in that direction. Therefore, through the coordinated action of the first drive assembly 2 and the second drive assembly 3, the positioning assembly 1 can move in both the first and second directions to adjust its position, allowing it to mate with the positioning holes of the A-pillar inner panels of different vehicle models to achieve positioning of the A-pillar inner panels for different vehicle models. The positioning device 10 of this application only needs to set one positioning component 1. The position of the positioning component 1 can be adjusted by the first driving component 2 and the second driving component 3 so that the position of the positioning component 1 corresponds to the positioning hole of the A-pillar inner panel, thereby realizing the positioning of the A-pillar inner panel of different models. This simplifies the structure of the positioning device 10 and saves the cost of the positioning device 10.

[0054] Furthermore, the cooperation between the positioning component 1 in the positioning device 10 and the positioning holes of the A-pillar inner panel of different vehicle models can make the structure of the positioning device 10 simpler and reduce the space occupied by the positioning component 1 in the positioning device 10, thereby making the structure of the positioning device 10 more compact. This facilitates the subsequent welding of the A-pillar inner panel and other parts of the vehicle body by the robot after positioning, so as to avoid interference between the welding trajectory of the positioning component 1 and the robot, thereby improving the welding quality and ensuring the assembly accuracy of the vehicle body.

[0055] In some examples, the positioning component 1 can be a hook cylinder, a positioning pin, etc.

[0056] In some embodiments, the second drive component 3 may include a first power structure 31 and a second power structure 32. The first power structure 31 is connected to the first drive component 2 and is used to drive the first drive component 2 to move along a second direction. The second power structure 32 is connected to the first power structure 31 and is used to drive the first power structure 31 to move along a second direction.

[0057] In this way, by connecting the first power structure 31 and the first drive assembly 2, and connecting the second power structure 32 and the first power structure 31, the second drive assembly 3 can form a secondary drive structure 22. Specifically, the second power structure 32 can drive the first power structure 31 to move along the second direction, and the first power structure 31 can drive the first drive assembly 2 to move along the second direction, further driving the positioning assembly 1 to move along the second direction, so as to adjust the position of the positioning assembly 1 in the second direction. Thus, through the setting of the secondary drive structure 22, the second power structure 32 can drive the positioning assembly 1 to move quickly to the vicinity of the target position in the second direction and perform initial positioning (i.e., coarse positioning). After the positioning assembly 1 moves to the vicinity of the target position in the second direction, the first power structure 31 can drive the positioning assembly 1 to move to the target position in the second direction and perform precise positioning, so as to balance the positioning accuracy and positioning efficiency of the positioning device 10.

[0058] In some other embodiments, the second drive assembly 3 may also include only the first power structure 31, which can also drive the first drive assembly 2 and the positioning assembly 1 to move along the second direction so that the positioning assembly 1 can be positioned in conjunction with the positioning hole of the A-pillar inner panel.

[0059] In some embodiments, please continue reading Figure 1 and Figure 4 The first power structure 31 may include a first support member 311, a power member 312, and a guide assembly 313. The first drive assembly 2 is connected to the first support member 311, and the power member 312 is connected to the second power structure 32, with the power member 312 also connected to the first support member 311, for driving the first support member 311 to move along a second direction. The guide assembly 313 is connected between the first support member 311 and the second power structure 32, for guiding the first drive assembly 2 in the second direction.

[0060] In this way, by connecting the first drive assembly 2 to the first support member 311, and the power component 312 to the second power structure 32 and connected to the first support member 311, the power output by the power component 312 can drive the first support member 311 to move along the second direction, further driving the first drive assembly 2 to move along the second direction. The first drive assembly 2 is connected to the positioning assembly 1, thereby driving the positioning assembly 1 to move along the second direction. Thus, the first power structure 31 can drive the positioning assembly 1 to move to the target position in the second direction. This driving method has a simple structure, high transmission efficiency, and allows for flexible adjustment of the position of the positioning assembly 1 in the second direction to achieve the matching of the positioning assembly 1 with the positioning holes of the A-pillar inner panel of different vehicle models.

[0061] Furthermore, by connecting the first drive assembly 2 to the first support member 311, the first support member 311 can support the first drive assembly 2, thereby improving the stability of the first drive assembly 2 moving in the second direction, further improving the stability of the positioning assembly 1 moving in the second direction, and realizing high-precision positioning of the positioning assembly 1 on the inner panel of the A-pillar.

[0062] Meanwhile, by connecting the guide component 313 between the first support member 311 and the second power structure 32, the guide component 313 can guide the first support member 311 so that the first support member 311 moves along the second direction according to the preset trajectory of the guide component 313, thereby avoiding trajectory errors such as deviation of the first support member 311 during the movement, which would affect the positioning accuracy of the positioning component 1.

[0063] In some examples, the first support member 311 can be a plate-like structure, a rod-like structure, a block-like structure, a strip-like structure, etc., and this application does not make specific limitations in this regard.

[0064] In some examples, the power component 312 can be a cylinder, an electric cylinder, a slide, etc.

[0065] In some embodiments, the guide assembly 313 includes a first component 3131 and a second component 3132 that are movable relative to each other in a second direction. The first component 3131 is connected to the second power structure 32, and the second component 3132 is connected to the first support member 311.

[0066] In this way, by connecting the first component 3131 to the second power structure 32 and the second component 3132 to the first support member 311, the second component 3132 can move relative to the second power structure 32 in the second direction, which further drives the first support member 311 to move relative to the second direction. The first support member 311 is connected to the first drive assembly 2, which can drive the first drive assembly 2 to move relative to the second direction. The first drive assembly 2 is connected to the positioning assembly 1, which further drives the positioning assembly 1 to move relative to the second direction, so as to flexibly adjust the position of the positioning assembly 1 in the second direction.

[0067] In some examples, the first component 3131 may include a slide rail and the second component 3132 may include a slider, thus enabling the second component 3132 to move relative to the first component 3131 in a second direction.

[0068] In some other examples, the first component 3131 may also be a guide rod, and the second component 3132 may also be a guide block. The guide block is arranged around the guide rod and can move on the guide rod, so that the second component 3132 can move relative to the first component 3131 in a second direction.

[0069] In some embodiments, the first power structure 31 may further include a first protective member 314, the first protective member 314 having a first protective space 314A, and the guide component 313 being disposed within the first protective space 314A.

[0070] In this way, the first protective component 314 provides a first protective space 314A, and the guide component 313 is located in the first protective space 314A. The first protective component 314 can protect the guide component 313 to prevent dust, chips and oil and other contaminants from coming into contact with the guide component 313, thereby preventing contaminants from entering the interior of the guide component 313, causing wear or damage, and extending the service life of the guide component 313.

[0071] Furthermore, by providing a first protective space 314A for a protective component and placing the guide component 313 within the first protective space 314A, the first protective space 314A can provide a stable internal environment for the guide component 313, thereby ensuring the long-term motion accuracy and reliability of the guide component 313.

[0072] In some embodiments, the first protective member 314 may include a first protective plate 3141, a second protective plate 3142, and a third protective plate 3143. In a second direction, the first protective plate 3141 is located on one side of the guide component 313, the second protective plate 3142 is located on the other side of the guide component 313, and the third protective plate 3143 is located between the first protective plate 3141 and the second protective plate 3142, and is connected to the first protective plate 3141 and the second protective plate 3142, so that the first protective plate 3141, the second protective plate 3142, and the third protective plate 3143 form a protective space.

[0073] In this way, the first protective plate 3141, the second protective plate 3142, and the third protective plate 3143 form a first protective space 314A, within which the guide assembly 313 is disposed. Thus, the first protective member 314 can protect the guide assembly 313, preventing wear or damage to it.

[0074] In some other embodiments, the first protective member 314 may further include a fourth protective plate and a fifth protective plate, which may be spaced apart along a third direction, perpendicular to the first direction and perpendicular to the second direction. Both the fourth and fifth protective plates are located between the first protective plate 3141 and the second protective plate 3142, and are both connected to the third protective plate 3143. Thus, the first protective member 314 can provide better protection for the guide assembly 313.

[0075] In some embodiments, the first support member 311 is provided with a relief groove 3111, which is recessed from the side surface of the first support member 311 facing the second power structure 32 away from the second power structure 32, and the relief groove 3111 penetrates the first support member 311 along the second direction, and a portion of the first protective member 314 is disposed in the relief groove 3111.

[0076] In this way, by setting the clearance groove 3111, part of the first protective member 314 (i.e., the third protective plate 3143) can be located in the clearance groove 3111, so as to facilitate the connection between the first support member 311 and the second component 3132 in the guide assembly 313. This can prevent the first support member 311 from interfering with the first protective member 314 during the movement, thus affecting the smoothness of the movement of the first support member 311.

[0077] Furthermore, by placing a portion of the first protective member 314 within the clearance groove 3111, the overall dimensions of the first protective member 314 and the first support member 311 in the first direction can be reduced, further reducing the dimensions of the first power structure 31 in the first direction, and even further reducing the dimensions of the second drive assembly 3 in the first direction, so as to make the structure of the second drive assembly 3 more compact.

[0078] In some embodiments, the positioning device 10 may further include a second support member 4, and the second power structure 32 is disposed on the second support member 4, and the second support member 4 fixes and supports the second power structure 32.

[0079] In this way, by placing the second power structure 32 on the second support member 4, the second support member 4 can fix and support the second power structure 32 to maintain the stability of the second power structure 32 and facilitate the installation of the second power structure 32.

[0080] In some examples, the second support member can be a plate-like structure, a rod-like structure, a block-like structure, a strip-like structure, etc., and this application does not specifically limit it.

[0081] In some embodiments, the second power structure 32 may have the same structure as the first power structure 31 in any of the above embodiments, and will not be described in detail here.

[0082] In some examples, the power component 312 of the second power structure 32 can be an electric cylinder, a slide, etc.

[0083] In some examples, please refer to [link / reference]. Figure 5The second power structure 32 may include a second protective member 321, which is used to protect the guide assembly of the second power structure 32. When the guide assembly of the second protective member 321 is a slide rail slider structure, the portions of the second protective member 321 located on both sides of the guide structure in the second direction can also limit the slider of the guide assembly 313 to prevent the slider from falling off the slide rail.

[0084] In some embodiments, please continue reading Figure 1 and Figure 2 The first driving component 2 may include a first connector 21 and a driving structure 22. The first connector 21 is connected to the first support 311. The driving structure 22 is connected to the first connector 21 and to the positioning component 1, and is used to drive the positioning component 1 to move relative to each other along a first direction.

[0085] In this way, the connection between the first support member 311 and the drive structure 22 can be easily facilitated by the first connector 21. By connecting the drive structure 22 to the first connector 21 and to the positioning component 1, the power output by the drive structure 22 can drive the positioning component 1 to move relative to each other along the first direction, thereby adjusting the position of the positioning component 1 in the first direction. This driving method has a simple structure, high transmission efficiency, and allows for flexible adjustment of the position of the positioning component 1 in the first direction.

[0086] In some examples, the first connector 21 can be a plate-like structure, a rod-like structure, a block-like structure, a strip-like structure, etc., and this application does not make specific limitations in this regard.

[0087] In some examples, the drive structure 22 may include a servo module, such as a slide driven by a servo motor, and the servo module is connected to the positioning component 1. In this way, the positioning component 1 can also be moved relative to the first direction.

[0088] In some embodiments, please continue reading Figure 1 and Figure 4 The power component 312 can drive the first support component 311 to move between the first position A1 and the second position A2. When the first support component 311 is in the first position A1, the positioning component 1 can cooperate with the positioning hole of the A-pillar inner panel for positioning. When the first support component 311 is in the second position A2, the positioning component 1 can separate from the A-pillar inner panel. The first power structure 31 also includes a first limiting component 315 and a second limiting component 316. Along the second direction, the first limiting component 315 is located on one side of the first support component 311, and the second limiting component 316 is located on the other side of the first support component 311. When the first support component 311 is in the first position A1, both the first limiting component 315 and the second limiting component 316 are in contact with and limited by the first support component 311.

[0089] Specifically, when the first support member 311 needs to be positioned at the first position A1, the positioning member 1 is first quickly moved to the target position in the first direction (i.e., aligned with the positioning hole of the A-pillar inner panel) by the first drive assembly 2, and then positioned there. Specifically, the drive structure 22 in the first drive assembly 2 drives the positioning member 1 to move toward the second drive assembly 3 in the first direction, so that it moves to the target position in the first direction.

[0090] Then, the positioning component 1, which has moved to the target position in the first direction, is rapidly moved to a position near the first position A1 in the second direction by the second power structure 32 in the second drive assembly 3, and initial positioning (i.e., coarse positioning) is performed on it. Specifically, the power output from the second power member 312 in the second power structure 32 drives the third support member to move relative to the second support member towards the inner panel of the A-pillar in the second direction. The third support member is connected to the first support member 311 in the first power structure 31, thereby driving the first support member 311 to move towards the inner panel of the A-pillar in the second direction. At the same time, the second guide assembly 313 guides the third support member so that the first support member 311 moves to a position near the first position A1.

[0091] Next, the positioning component 1 is moved to the target position in the second direction by the first power structure 31 in the second drive assembly 3, and is precisely positioned there. Specifically, the power output from the power component 312 in the first power structure 31 drives the first support component 311 to move further toward the inner A-pillar panel in the second direction relative to the third support component. At the same time, the guide assembly 313 guides the first support component 311 so that it moves to the first position A1. At this time, both the first limiting component 315 and the second limiting component 316 are in contact with the first support component 311, which can limit the position of the first support component 311 when it is in the first position A1, so as to realize the positioning component 1 and the positioning hole of the inner A-pillar panel for positioning.

[0092] When it is necessary to position the first support member 311 in the second position A2, firstly, the first support member 311 is released from the limit by at least one of the first limiting member 315 and the second limiting member 316, so that the power member 312 can drive the first support member 311 to move away from the inner plate of the A-pillar in the second direction relative to the third support member, so that the first support member 311 moves to a position near the first position A1, that is, the position where the second power structure 32 roughly positions the first support member 311.

[0093] Then, the second power member 312 drives the third support member to move further away from the inner A-pillar panel in the second direction relative to the second support member. The third support member is connected to the first support member 311, thereby driving the first support member 311 to move further away from the inner A-pillar panel in the second direction, so that the first support member 311 moves to the second position A2, which is the position when the second power member 312 does not drive the positioning component 1.

[0094] Next, the first driving component 2 drives the positioning component 1 to move away from the second driving component 3 in a first direction relative to the second driving component 3, so that the positioning component 1 moves quickly to the initial position in the first direction, that is, the position when the first driving component 2 does not drive the positioning component 1.

[0095] In this way, along the second direction, by placing the first limiting member 315 on one side of the first support member 311 and the second limiting member 316 on the other side of the first support member 311, when the first support member 311 is in the first position A1, both the first limiting member 315 and the second limiting member 316 can contact and limit the first support member 311. That is, in the first position A1, the first limiting member 315 and the second limiting member 316 limit the first support member 311 from both sides of the first support member 311 in the second direction, ensuring the stability of the first support member 311, thereby ensuring the stability of the first drive assembly 2 and the positioning assembly 1, so that the positioning assembly 1 remains stable when positioning with the inner panel of the A-pillar, improving the positioning effect.

[0096] In some embodiments, at least one of the first limiting member 315 and the second limiting member 316 may include a driving part 3151 and a limiting part 3152. The driving part 3151 is connected to the limiting part 3152 and is used to drive the limiting part 3152 to move so that when the first support member 311 is in the first position A1, the limiting part 3152 contacts and limits the first support member 311, and when the first support member 311 is in the second position A2, the limiting part 3152 separates from the first support member 311.

[0097] In this way, when the first support member 311 is in the first position A1, the driving unit 3151 drives the limiting part 3152 to move to contact the first support member 311, thereby limiting the contact of the first support member 311. When the first support member 311 is in the second position A2, at least one of the first limiting part 315 and the second limiting part 316 releases the limiting of the first support member 311, and the driving unit 3151 drives the limiting part 3152 to move to separate from the first support member 311. This limiting method has a simple structure, high positioning accuracy, and is easy to implement.

[0098] In some examples, the structure of the first limiting member 315 may differ from the structure of the second limiting member 316. Alternatively, the structure of the first limiting member 315 may be the same as the structure of the second limiting member 316. For example, both the first limiting member 315 and the second limiting member 316 may be plate-like structures, rod-like structures, block-like structures, strip-like structures, etc.

[0099] This application is illustrated by way of the difference between the structure of the first limiting member 315 and the structure of the second limiting member 316.

[0100] In some embodiments, the first limiting member 315 may include a driving part 3151 and a limiting part 3152, wherein the driving part 3151 is connected to the limiting part 3152 and is used to drive the limiting part 3152 to move. The second limiting member 316 may include a second limiting plate 3161 and a second connecting plate 3162, wherein the second connecting plate 3162 is used to connect to the second limiting plate 3161 and to the third support member.

[0101] In this way, the installation of the second limiting plate 3161 can be facilitated by the setting of the second connecting plate 3162. When the first support member 311 moves from the second position A2 to the first position A1, the power member 312 drives the first support member 311 to move towards the inner panel of the A-pillar in the second direction until the first support member 311 and the second limiting plate 3161 come into contact, and the second limiting plate 3161 contacts and limits the first support member 311 on one side in the second direction. At the same time, the driving unit 3151 drives the limiting unit 3152 to move to contact the first support member 311, so as to contact and limit the first support member 311 on the other side in the second direction. In this way, both the first limiting member 315 and the second limiting member 316 can be contacted and limited with the first support member 311.

[0102] In some examples, the drive unit 3151 can be a rotary cylinder, and for example, the rotation angle of the rotary cylinder can be 90°. In the initial state of the rotary cylinder, the angle is 0°, at which point the limiting part 3152 is separated from the first support member 311. After the first support member 311 is in the first position A1, the rotary cylinder rotates 90° to bring the limiting part 3152 and the first support member 311 into contact. When it is necessary to move the first support member 311 to the second position A2, the rotary cylinder rotates back to the initial state to separate the limiting part 3152 and the first support member 311, facilitating the power member 312 to drive the first support member 311 to move away from the inner A-pillar panel relative to the third support member in a second direction.

[0103] In some examples, the limiting part 3152 can be a plate-like structure, a rod-like structure, a block-like structure, a strip-like structure, etc., and this application does not make specific limitations in this regard.

[0104] In some examples, the second limiting plate 3161 can be made of a flexible material, such as rubber or polyurethane. This allows for flexible positioning of the first support member 311 and the second limiting plate 3161, preventing damage to the first support member 311 from excessively hard material.

[0105] In some examples, in the second direction, the first power structure 31 may further include a third connector 317, which is located between the first support 311 and the second limiting member 316 and is connected to the first support 311. For example, the third connector 317 may be made of a flexible material. This allows for better flexible limiting of the first support 311 and the second limiting plate 3161.

[0106] In some embodiments, please continue reading Figure 1 and Figure 3 The positioning component 1 may also include a first hook cylinder 11 and a second hook cylinder 12 arranged at intervals along the first direction. Both the first hook cylinder 11 and the second hook cylinder 12 are used to cooperate with the positioning holes of the inner plate of the A-pillar.

[0107] The first hook-pin cylinder 11 may include a first positioning pin and a first clamping member. The first positioning pin has a first guide groove, and the first clamping member is disposed in the first guide groove. The second hook-pin cylinder 12 may include a second positioning pin and a second clamping member. The second positioning pin has a second guide groove, and the second clamping member is disposed in the second guide groove.

[0108] Specifically, when the first support member 311 needs to be positioned at the first position A1, that is, when the first hook cylinder 11 and the second hook cylinder 12 in the positioning assembly 1 are both engaged with the positioning holes in the inner A-pillar panel. Specifically, the power member 312 drives the first support member 311 to move relative to the third support member toward the inner A-pillar panel in the second direction. The first support member 311 is connected to the positioning assembly 1, thereby driving the first hook cylinder 11 and the second hook cylinder 12 in the positioning assembly 1 to move toward the inner A-pillar panel in the second direction until the first hook cylinder 11 and the second hook cylinder 12 are both engaged with the positioning holes in the inner A-pillar panel. During the above movement, the first clamping member is compressed in the first guide groove, and the second clamping member is compressed in the second guide groove, so that the first positioning pin and the second positioning pin are both inserted into the positioning holes in the inner A-pillar panel. After the first and second positioning pins are both inserted into the positioning holes in the inner A-pillar panel, the second hook-pin cylinder 12 drives the first clamping member to move in the first guide groove along the second direction toward the inner A-pillar panel, so that the side of the inner A-pillar panel facing away from the positioning assembly 1 contacts the first clamping member. Simultaneously, the first clamping member extends upward in the first guide groove along the first direction to clamp the first clamping member. At the same time, the second hook-pin cylinder 12 performs the same action, driving its second clamping member to complete the clamping.

[0109] In this way, due to the unique "insertion-clamping" action mechanism of the first and second hook-pin cylinders 11 and 12, precise positioning can be provided to ensure that both the first and second hook-pin cylinders 11 and 12 mate with the positioning holes of the A-pillar inner panel. On the other hand, the first and second hook-pin cylinders 11 and 12 can also provide strong active clamping, which can effectively resist vibration and thermal deformation during subsequent dynamic processes such as welding, ensuring that the A-pillar inner panel always remains in the first position A1, thus providing a fundamental guarantee for achieving high-precision body manufacturing.

[0110] In some embodiments, the positioning component 1 may further include a first fixing member 13, a second fixing member 14, and a first gasket 15. The first fixing member 13 is connected to the first driving component 2, and the second fixing member 14 is connected to the first fixing member 13 in a third direction (e.g., Figure 3 On one side of the direction C), the third direction is perpendicular to the first direction and perpendicular to the second direction. The first gasket 15 is detachably connected between the first fixing member 13 and the second fixing member 14. The first hook cylinder 11 is connected to the second fixing member 14.

[0111] In this way, the first fixing member 13 and the second fixing member 14 facilitate the connection between the first drive assembly 2 and the first hook cylinder 11, thereby enabling the disassembly and maintenance of the first hook cylinder 11. The first gasket 15, detachably connected between the first fixing member 13 and the second fixing member 14, allows adjustment of the dimensional error of the positioning holes of the first hook cylinder 11 and the A-pillar inner panel in the third direction, ensuring precise alignment of the positioning holes of the first hook cylinder 11 and the A-pillar inner panel in the third direction.

[0112] In some examples, there can be multiple first gaskets 15, which are stacked in the third direction. In this way, the dimensional error of the positioning holes of the first hook cylinder 11 and the A-pillar inner panel in the third direction can be flexibly adjusted by increasing or decreasing the number of first gaskets 15 according to actual needs, so as to ensure the precise alignment of the positioning holes of the first hook cylinder 11 and the A-pillar inner panel.

[0113] In some examples, the first fastener 13 and the second fastener 14 can be plate-like structures, rod-like structures, block-like structures, strip-like structures, etc., and this application does not make specific limitations in this regard.

[0114] In some embodiments, the first hook cylinder 11 is connected to one side of the second fixing member 14 in the second direction, for example, the first hook cylinder 11 is connected to the side of the second fixing member 14 facing the inner panel of the A-pillar. The positioning assembly 1 may also include a second gasket 16, which is detachably connected between the first hook cylinder 11 and the second fixing member 14.

[0115] In this way, by detachably connecting the second gasket 16 between the first hook cylinder 11 and the second fixing member 14, the dimensional error of the positioning hole of the first hook cylinder 11 and the inner plate of the A-pillar in the second direction can be adjusted to ensure the precise alignment of the positioning hole of the first hook cylinder 11 and the inner plate of the A-pillar in the second direction.

[0116] In some examples, there can be multiple second gaskets 16, which are stacked in the second direction. In this way, the dimensional error of the positioning hole of the first hook cylinder 11 and the A-pillar inner panel in the second direction can be flexibly adjusted by increasing or decreasing the number of second gaskets 16, so as to ensure the precise alignment of the positioning hole of the first hook cylinder 11 and the A-pillar inner panel.

[0117] In some embodiments, the positioning component 1 may further include a third fixing member 17, a third gasket 18, and a fourth gasket 19. The third fixing member 17 is connected to the first fixing member 13 on the third-facing side. The third gasket 18 is detachably connected between the first fixing member 13 and the third fixing member 17. The second hook cylinder 12 is connected to the side of the third fixing member 17 facing the inner A-pillar panel. The fourth gasket 19 is detachably connected between the second hook cylinder 12 and the third fixing member 17.

[0118] The structure of the third fastener 17 can be the same as that of the second fastener 14, the structure of the third gasket 18 can be the same as that of the first gasket 15, the structure of the fourth gasket 19 can be the same as that of the second gasket 16, and the connection method of the third fastener 17, the third gasket 18 and the fourth gasket 19 can be the same as the connection method of the second fastener 14, the first gasket 15 and the second gasket 16, which will not be described in detail here.

[0119] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
