[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] like Figures 1 to 3 As shown, an embodiment of the present invention provides an assembly device for a chassis, comprising:

[0034] A base 100 is provided with a pair of first slide rails 102;

[0035] A pair of lifting support bases 104 slidably mounted on the first slide rail 102 , the lifting support bases 104 being used to support the chassis;

[0036] A pair of pressing assemblies 106 are installed on the top of the lifting support base 104. The pressing assemblies 106 are used to make the bottom frame close to the top of the lifting support base 104.

[0037] The deflection detection member is mounted on the base 100 to detect the deflection of the chassis and / or the vehicle body.

[0038] According to the assembly device for the chassis provided by the embodiment of the present invention, a pair of first slide rails 102 and a slidably mounted lifting support seat 104 are provided, so that the assembly device can easily adapt to chassis of different sizes and types, thereby improving the versatility and flexibility of the equipment; by adjusting the position of the lifting support seat 104, it can be ensured that the chassis is always in the best support state during the assembly process. The setting of the clamping component 106 effectively solves the problem of shaking or misalignment that may occur in the chassis during the assembly process. By uniformly applying pressure to the chassis by the clamping component 106, the chassis is tightly fitted to the top of the lifting support seat 104, thereby ensuring the accuracy and stability of the chassis assembly and reducing the workload of subsequent adjustments. By setting the deflection detection part, the deflection changes of the chassis and / or the vehicle body can be monitored in real time during the assembly process, which is of great significance for evaluating the assembly quality and preventing potential structural problems. By obtaining deflection data in a timely manner, the operator can quickly adjust the assembly parameters or take remedial measures to ensure the structural strength and safety of the final product. The overall structure of the assembly device is compact and rational. By precisely controlling the chassis assembly process and monitoring changes in deflection in real time, the chassis assembly device provided by the present invention can improve chassis assembly quality and efficiency. Furthermore, when the chassis structure and dimensions change, flexible adaptation can be achieved by introducing multiple sets of the assembly device.

[0039] Please continue to see Figures 1 to 3The present invention aims to provide an efficient and precise chassis assembly device to address issues such as unstable chassis support, low assembly accuracy, and the inability to detect deflection in real time in traditional assembly methods. The device primarily comprises a base 100, a lifting support 104, a clamping assembly 106, and a deflection detection element.

[0040] The base 100 serves as the foundation of the entire assembly device, and a pair of parallel first slide rails 102 are designed on the base 100. These slide rails not only provide a stable sliding track for the lifting support base 104, but also ensure the linearity and accuracy of the lifting support base 104 during movement.

[0041] A pair of lift supports 104 are slidably mounted on the first rail 102 of the base 100. As will be appreciated, each lift support 104 has a lifting function and can be adjusted to the height requirements of different chassis to ensure that the chassis is firmly supported during assembly. Furthermore, the sliding design of the lift supports 104 allows them to flexibly adapt to chassis of varying sizes, enhancing the versatility of the device.

[0042] The pressing assembly 106 is installed on the top of the lifting support 104 to ensure the accuracy of the chassis assembly. The deposit assembly applies appropriate pressure to make the chassis fit tightly to the top of the lifting support 104, thereby eliminating the shaking and misalignment of the chassis during the assembly process.

[0043] To monitor the deflection of the chassis and / or vehicle body in real time, the chassis assembly device includes a deflection detector mounted on base 100. This deflection detector accurately measures the degree of deformation of the chassis or vehicle body during assembly, providing operators with timely and accurate deflection data. Furthermore, the deflection detector enables real-time uploading of deflection measurement data.

[0044] The uniform pressure applied by the clamping assembly 106 to the chassis ensures a constant close fit during assembly, significantly improving assembly precision and stability. The lifting and sliding capabilities of the lifting support 104 allow the assembly device to easily adapt to chassis of varying sizes and types, enhancing the device's versatility and flexibility. The provision of a deflection detector enables real-time monitoring of chassis and / or vehicle body deflection.

[0045] According to one embodiment of the present invention, the lifting support base 104 includes:

[0046] The first sliding seat 108 is slidably mounted on the first slide rail 102;

[0047] The lifting base 110 is mounted on the first sliding base 108;

[0048] The lifting column 112 is telescopically mounted on the lifting base 110 .

[0049] like Figures 1 to 3 As shown, in the embodiment of the present invention, the lifting support seat 104 includes three key parts: a first sliding seat 108 , a lifting base 110 and a lifting column 112 .

[0050] The first sliding seat 108 is a connecting component between the lifting support seat 104 and the base 100, and is slidably mounted on the first slide rail 102 on the base 100. This design allows the lifting support seat 104 to move freely along the slide rail, thereby adjusting according to the width of the chassis, ensuring that the chassis is evenly supported during assembly.

[0051] The lifting base 110 is mounted on the top of the first sliding base 108 and serves as a support platform for the lifting columns 112 . The lifting base 110 provides sufficient strength and stability to bear the weight of the lifting columns 112 and the base frame.

[0052] The lifting base 110 may also be provided with a corresponding guide mechanism for guiding the vertical movement of the lifting column 112 to ensure a smooth and accurate lifting process.

[0053] The lifting column 112 is telescopically mounted on the lifting base 110 and is used to adjust the height of the lifting support base 104. The lifting column 112 can use a threaded pair, a hydraulic cylinder, a pneumatic cylinder or an electric push rod to achieve its telescopic movement.

[0054] The telescopic function of the lifting columns 112 allows the lifting support base 104 to easily adapt to chassis of varying heights, ensuring optimal support during assembly. The sliding function of the first sliding base 108 along the guide rails allows for adjustable spacing between the lifting support bases 104, accommodating chassis of varying lengths and enhancing the versatility and flexibility of the device. The robust design of the lifting base 110 and lifting columns 112, along with the provision of a guide mechanism, ensures the stability and reliability of the lifting support base 104 during both the lifting and support processes.

[0055] According to an embodiment of the present invention, a mounting seat 114 is provided on the top of the lifting column 112 , and the pressing assembly 106 is slidably connected to the mounting seat 114 .

[0056] like Figures 1 to 3As shown, in an embodiment of the present invention, in order to further improve the flexibility and accuracy of the chassis assembly, the top of the lifting column 112 is designed to be provided with a mounting seat 114, and the clamping assembly 106 is installed on the mounting seat 114 through a slidable connection. This arrangement allows the clamping assembly 106 to be fine-tuned according to the specific shape and size of the chassis during the assembly process to ensure that the chassis can fit tightly and evenly on the top of the lifting support seat 104.

[0057] Specifically, a mounting base 114 is fixed to the top of the lifting column 112 and serves as a support platform for the clamping assembly 106. The mounting base 114 has a guide groove, guide rail, or other form of guide mechanism to enable the clamping assembly 106 to slide along a predetermined path. The clamping assembly 106 is connected to the mounting base 114 via a matching slider, roller, or other sliding element, thereby achieving a slidable connection.

[0058] The slidable connection design between the clamping assembly 106 and the mounting base 114 enables the clamping assembly 106 to flexibly adapt to chassis of different shapes and sizes, thereby improving the versatility and flexibility of the assembly device. By adjusting the position of the clamping assembly 106 on the mounting base 114, the operator can achieve precise clamping of the chassis, ensuring that the chassis is always in the best condition during the assembly process, thereby improving the accuracy of the assembly. The slidable connection method simplifies the adjustment process of the clamping assembly 106, and the operator can easily make fine adjustments according to the actual situation of the chassis, thereby improving work efficiency. Comprehensive and uniform clamping can ensure that the chassis remains stable during the assembly process, reducing the occurrence of shaking and misalignment, thereby improving the stability and reliability of the assembly. This design enables the assembly device to be widely used in the assembly process of various types of chassis, whether it is a simple small component or a complex large structural part, it can be effectively supported and clamped.

[0059] According to an embodiment of the present invention, a second slide rail 116 is provided on the mounting seat 114 , and the pressing assembly 106 is slidably connected to the second slide rail 116 .

[0060] like Figures 1 to 3 As shown, in an embodiment of the present invention, in order to further optimize the adjustment flexibility and operational convenience of the clamping assembly 106, a second slide rail 116 is designed on the mounting seat 114, and the clamping assembly 106 is slidably connected to these second slide rails 116 through a specific connecting mechanism, so that the clamping assembly 106 can perform precise linear movement along the second slide rail 116, thereby achieving precise clamping of different areas of the chassis.

[0061] Specifically, the second slide rail 116 is mounted on top of the mounting base 114, and its length and position are customized according to the expected size and shape of the chassis. The second slide rail 116 can be a linear guide, ball screw or other high-precision sliding mechanism to ensure the stability and accuracy of the clamping assembly 106 during the sliding process.

[0062] The clamping assembly 106 is equipped with sliding elements such as sliders or rollers that match the second slide rail 116. These elements are installed at the bottom of the clamping assembly 106 to closely match the second slide rail 116. The operator can easily control the clamping assembly 106 to slide along the second slide rail 116, thereby adjusting the clamping force of different areas of the chassis.

[0063] The provision of the second slide rail 116 enables the clamping assembly 106 to perform precise linear movement along a predetermined path, thereby greatly improving the flexibility and accuracy of adjustment. The position of the clamping assembly 106 can be adjusted through simple operations without the need for complex tools or cumbersome steps, significantly improving the convenience of operation. Since the clamping assembly 106 can slide precisely along the second slide rail 116, it is easier to achieve uniform compression of different areas of the chassis, improving the accuracy and stability of assembly. This design enables the clamping assembly 106 to better adapt to chassis of different shapes and sizes, improving the versatility and flexibility of the assembly device. By optimizing the adjustment method of the clamping assembly 106, the adjustment time and labor costs during the assembly process are reduced, thereby improving the overall production efficiency.

[0064] In addition, it should be noted that through the setting of the first slide rail 102, the second slide rail 116 and the lifting support seat 104, the assembly device can be adjusted in the height, width and length directions during the assembly process of the base frame to meet the assembly requirements of base frames of different specifications.

[0065] According to one embodiment of the present invention, the pressing assembly 106 includes:

[0066] The pressing platform 118 is fixedly connected to the mounting base 114.

[0067] The second sliding seat 120 is slidably mounted on the second slide rail 116 . A pressing head 122 is provided on the second sliding seat 120 . The pressing head 122 is spaced apart from the top of the pressing platform 118 . The pressing head 122 is suitable for pressing the side beam of the chassis to the top of the pressing platform 118 .

[0068] like Figures 1 to 3 As shown, in the embodiment of the present invention, the pressing assembly 106 mainly includes three key parts: a pressing platform 118, a second sliding seat 120 and a pressing head 122. The three parts work together to ensure the stability and accuracy of the chassis during the assembly process.

[0069] The pressing platform 118 is the base of the pressing assembly 106 and is fixedly connected to the mounting base 114. The mounting base 114 is located on the top of the lifting column 112 and provides a stable support platform for the pressing assembly 106.

[0070] The top of the pressing platform 118 is designed with a contact surface that matches the side beams of the chassis to ensure that the chassis can be evenly stressed during the pressing process.

[0071] The second sliding seat 120 is the moving part of the clamping assembly 106, and is slidably mounted on the second slide rail 116 on the mounting seat 114, so that the second sliding seat 120 can perform precise linear movement along the second slide rail 116, thereby achieving clamping of different positions of the chassis side beam.

[0072] The pressing head 122 is mounted on the top of the second sliding seat 120 and is the part of the pressing assembly 106 that directly acts on the chassis side beam. The pressing head 122 is spaced apart from the top of the pressing platform 118 to form an adjustable pressing space to accommodate chassis side beams of different thicknesses.

[0073] The pressing head 122 can be made of elastic materials such as rubber, spring steel, etc., so as to provide a certain buffer and adaptability during the pressing process. At the same time, the shape and size of the pressing head 122 may also be customized according to the specific shape of the chassis side beam to ensure the accuracy and stability of the pressing.

[0074] The pressing head 122 may also be equipped with a pressure sensor or an adjusting device to monitor and adjust the pressing force in real time to prevent excessive pressing or damage to the chassis side beams.

[0075] Through the coordinated action of the clamping head 122 and the clamping platform 118, precise clamping of the chassis side beams is achieved, ensuring the stability and precision of the chassis during the assembly process. The sliding function of the second sliding seat 120 along the second slide rail 116 enables the clamping assembly 106 to easily adapt to chassis side beams of different positions and shapes, thereby improving the versatility and flexibility of the equipment. The clamping head 122 is made of elastic material and is equipped with a pressure sensor or adjustment device when necessary, which effectively prevents excessive clamping or damage to the chassis side beams. By optimizing the design of the clamping assembly 106, the adjustment time and labor cost during the assembly process are reduced, and the overall production efficiency is improved. This design enables the clamping assembly 106 to be widely used in the assembly process of various types of chassis, whether it is a small household appliance chassis or a large industrial equipment chassis, it can be effectively clamped and supported.

[0076] According to one embodiment of the present invention, the gap between the pressing head 122 and the pressing platform 118 is adjustable.

[0077] In this embodiment of the present invention, to further enhance the adaptability and flexibility of the clamping assembly 106, the gap between the clamping head 122 and the clamping platform 118 is designed to be adjustable. This design allows the operator to precisely adjust the distance between the clamping head 122 and the clamping platform 118 based on the thickness and shape of the chassis side beams, thereby ensuring optimal support and stability for the chassis during the clamping process.

[0078] In order to achieve the function of adjustable gap, the pressing assembly 106 may adopt one or a combination of the following methods:

[0079] Threaded adjustment mechanism: A threaded rod or sleeve can be mounted on the pressing head 122. This threaded rod or sleeve passes through the second sliding seat 120 and engages with a threaded hole in the pressing head 122 or the pressing platform 118. By rotating the threaded rod or sleeve, the gap between the pressing head 122 and the pressing platform 118 can be precisely adjusted.

[0080] Spring buffer mechanism: A spring or other elastic element is placed between the pressing head 122 and the pressing platform 118 to provide an adjustable buffering effect. By adjusting the spring preload or replacing springs of different stiffness, the contact force between the pressing head 122 and the pressing platform 118 can be changed, thereby indirectly adjusting the gap size.

[0081] Latch positioning mechanism: Multiple positioning holes are provided on the pressing head 122 and / or the pressing platform 118. Latch pins are inserted into the positioning holes at different locations to fix the relative position between the pressing head 122 and the pressing platform 118. While this method is not as precise as a threaded adjustment mechanism, it is simple and quick to operate, making it suitable for scenarios where quick adjustments are required.

[0082] Motor-driven adjustment: For applications requiring high automation and precise control, a motor-driven method can be used to adjust the gap between the pressing head 122 and the pressing platform 118. The motor drives the transmission mechanism such as the lead screw and gears to move the pressing head 122 in a specific direction to achieve the purpose of adjusting the gap.

[0083] By adjusting the gap between the pressing head 122 and the pressing platform 118, it is possible to adapt to chassis side beams of different thicknesses and shapes, thereby improving the versatility and flexibility of the pressing assembly 106. Precise gap adjustment ensures that the chassis receives optimal support and stability during the pressing process, reducing the risk of deformation or damage due to uneven pressing. The design with adjustable gap helps to achieve precise alignment and pressing of the chassis side beams, thereby improving the accuracy and quality of the overall assembly. Regardless of the adjustment method used, it is intended to simplify the operating process and reduce adjustment time, thereby improving the work efficiency and comfort of the operator. By optimizing the design of the pressing assembly 106, equipment failures and downtime caused by improper pressing are reduced, and the reliability and stability of the equipment are improved.

[0084] According to an embodiment of the present invention, a connecting beam 124 is provided between the mounting seats 114 on the pair of lifting columns 112 .

[0085] like Figures 1 to 3 As shown, in the embodiment of the present invention, in order to enhance the structural stability and rigidity between the pair of lifting columns 112 and improve the load-bearing capacity of the entire lifting support base 104, a connecting beam 124 is specially provided. The connecting beam 124 is arranged between the mounting bases 114 at the top of the two lifting columns 112.

[0086] The connecting beam 124 spans the two mounting seats 114 and is firmly mounted at a predetermined position on each mounting seat 114 by welding, bolting or other reliable fixing methods. In this way, the connecting beam 124 not only strengthens the connection between the lifting columns 112, but also forms a stable frame structure. The connecting beam 124 is usually made of high-strength, high-rigidity materials such as steel, aluminum alloy, etc., to ensure that it can withstand the pressure and torque generated by the base frame and the heavy objects on it. At the same time, the design of the connecting beam 124 also takes into account the lightweight material to reduce the weight of the overall structure and improve operating efficiency. The shape and size of the connecting beam 124 are customized according to the specific needs and design of the lifting support seat 104.

[0087] In addition to the basic connection and support functions, the connecting beam 124 can also be expanded as needed. For example, auxiliary equipment such as sensors and lighting devices can be installed on the connecting beam 124 to improve the intelligence level and operational convenience of the lifting support base 104.

[0088] The provision of the connecting beam 124 significantly enhances the connection strength and rigidity between the lifting columns 112, making the entire lifting support base 104 more stable and reliable when bearing heavy objects. By optimizing the design of the connecting beam 124, the load-bearing capacity of the lifting support base 104 can be further improved to meet the assembly requirements of heavier weights and more complex chassis. The provision of the connecting beam 124 enables the space between the lifting columns 112 to be rationally utilized, optimizing the layout and aesthetics of the overall structure. The enhanced structural stability and load-bearing capacity mean that the lifting support base 104 is safer and more reliable during operation, reducing the risk of safety accidents caused by structural failure. As an important component of the lifting support base 104, the modular design of the connecting beam 124 makes equipment maintenance and upgrading more convenient and quick.

[0089] According to one embodiment of the present invention, the base 100 includes:

[0090] A pair of base bodies 126 , the first slide rail 102 is disposed on the base bodies 126 ;

[0091] The reinforcement beam 128 is connected between the pair of base bodies 126 .

[0092] like Figures 1 to 3 As shown, in the embodiment of the present invention, the base 100 serves as the supporting base of the entire device and is designed to be a stable and easily adjustable structure. The base 100 mainly includes a pair of base bodies 126 and a reinforcement beam 128 connected between the pair of base bodies 126.

[0093] The base bodies 126 are the main body of the base 100, arranged symmetrically and used to support key components such as the lifting columns 112. A first rail 102 is provided on the upper surface of each base body 126. The first rail 102 can be a linear guide, T-slot, or other sliding mechanism, allowing the lifting columns 112 to move smoothly along their length.

[0094] Reinforcement beam 128 is connected between the pair of base bodies 126 and its primary function is to enhance the overall rigidity and stability of base 100. Reinforcement beam 128 can be made of rectangular tubes, I-beams, or other high-strength structural materials, and its cross-sectional shape and size are customized according to the load-bearing capacity and design requirements of base 100.

[0095] The reinforcing beams 128 can be installed between a pair of base bodies 126 by welding, bolting or other reliable fixing methods to form a stable triangular or quadrilateral support structure (depending on the number and arrangement of the reinforcing beams 128) to effectively resist deformation and distortion caused by external forces.

[0096] The provision of reinforcement beams 128 significantly enhances the overall rigidity and stability of base 100, making the equipment more stable and reliable during operation, and reducing performance degradation and safety hazards caused by vibration or external interference. By optimizing the structural design of base body 126 and reinforcement beams 128, the load-bearing capacity of base 100 has been significantly improved, meeting the support requirements of heavier and more complex equipment.

[0097] According to an embodiment of the present invention, a mounting hole 130 is defined on an edge of the base body 126 , and a fastener is passed through the mounting hole 130 to fix the base body 126 in the mounting position.

[0098] like Figures 1 to 3 As shown, in the embodiment of the present invention, in order to ensure that the base body 126 can be firmly fixed on the predetermined installation position, a mounting hole 130 is opened on the edge of the base body 126, and is fixed by inserting fasteners.

[0099] Mounting holes 130 are typically located at the edges of base body 126, avoiding key stress points and structural weaknesses. This ensures effective fixation without compromising the overall strength of base body 126. The number of mounting holes 130 can be determined based on the size and weight of base body 126, as well as the specific requirements of the mounting location. Generally, sufficient fixing points should be provided to distribute stress and enhance stability and reliability. Mounting holes 130 are typically circular or oblong in shape to facilitate insertion and securement of fasteners (e.g., bolts, screws, etc.).

[0100] By providing mounting holes 130 and installing fasteners, base body 126 is securely fixed to the mounting location, effectively preventing displacement or loosening due to vibration or external forces during operation. The mounting location can be the ground or other flat surface. This secure fixing ensures the overall stability of the device during operation and reduces the risk of safety accidents caused by device shaking or collapse.

[0101] According to one embodiment of the present invention, at least two groups of assembling devices for the base frame are arranged at intervals along the length direction of the base frame.

[0102] The assembly devices are spaced evenly or unevenly along the length of the chassis. This layout ensures that all components are stably and precisely supported and positioned throughout the chassis assembly process. At least two sets of assembly devices are provided to meet basic assembly requirements. However, in actual applications, the number of assembly devices can be flexibly increased to improve assembly stability and efficiency, depending on the length, weight, and complexity of the chassis.

[0103] By placing multiple assembly units at intervals, multiple chassis sections can be assembled in parallel, significantly reducing assembly time. The number and layout of assembly units can be flexibly adjusted according to the length and complexity of the chassis, making the assembly unit widely applicable and flexible.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
