Description

Technical Field

[0001] This application relates to the field of automotive frame and base welding technology, and in particular to a workbench for welding a combination of frame and base. Background Technology

[0002] In the field of automotive chassis manufacturing technology, the stable connection between the frame and the base is a crucial step in ensuring the structural strength and driving safety of the vehicle. In traditional processes, the frame is usually connected to the base by welding, a process that requires extremely high precision and stability, with welding required to both sides of the base to the frame.

[0003] To ensure uniform welding quality and structural symmetry of the main beams on both sides of the base, the base needs to be centered when placed on the workbench. This step not only affects the strength and aesthetics of the welded joint but also directly impacts the durability and safety of the final product. Currently, operators often rely on experience and simple measuring tools to manually adjust the base position to achieve the centering requirement. This method is not only time-consuming but also highly susceptible to human error, making it difficult to achieve efficient and precise positioning, resulting in low production efficiency and increased costs. Utility Model Content

[0004] The main purpose of this application is to provide a workbench for welding the main beam and the base assembly, which aims to solve the technical problem that in the prior art, operators often rely on experience and simple measuring tools to manually adjust the position of the base, which is not only time-consuming but also greatly affected by human factors, making it difficult to achieve efficient and accurate positioning.

[0005] To achieve the above objectives, this application provides a workbench for welding a main beam and a base assembly, comprising:

[0006] A support platform, used to support the base;

[0007] Two movable platforms are arranged on both sides of the support platform, and the movable platforms are used to place the main beam;

[0008] Each of the two movable platforms is provided with at least one adjustment component. The two movable platforms can move in a direction that is closer to or farther from the support platform. The distance between the two movable platforms and the support platform is always equal. The adjustment component can abut against the base and drive the base to move so that the distance between the base and the two beams is equal.

[0009] Optionally, the adjustment assembly includes a lifting block and an abutment rod;

[0010] The movable platform is provided with a through hole for the lifting block to pass through. The through hole is located between the main beam and the base. The upper end of the lifting block is provided with a receiving groove. The receiving groove extends through the outer wall of the lifting block on the side near the support platform. The first end of the abutment rod is located in the receiving groove. A pin is provided in the receiving groove. The pin passes through the first end of the abutment rod. The second end of the abutment rod can rotate around the axis of the pin so that the abutment rod can switch between a horizontal and a vertical state. When the abutment rod is in a horizontal state, its second end can abut against the base. When the abutment rod is in a vertical state, it can move through the through hole to the bottom of the movable platform.

[0011] Optionally, the moving platform is provided with a guide groove, the guide groove having a guide slope extending to the through hole, so that when the lifting block moves downward, the guide slope can abut against the outer wall of the abutting rod, guiding the abutting rod from a horizontal state to a vertical state. The guide slope is located between the through hole and the support platform, and the guide slope gradually slopes downward in the direction away from the support platform.

[0012] Optionally, an elastic element is provided at the upper end of the receiving groove. The elastic element is located on the side of the abutment rod away from the support platform. The elastic element is used to apply a thrust to the abutment rod when it recovers its elastic deformation.

[0013] Optionally, the second end of the abutment rod has a threaded hole extending axially, and a compensating rod is threadedly connected to the threaded hole. The distance between the end of the compensating rod located outside the threaded hole and the pin is adjustable.

[0014] Optionally, a connecting plate is provided below the mobile platform, the connecting plate being used to connect all the lifting blocks on the same mobile platform, and the connecting plate being connected to a telescopic component for driving its lifting and moving.

[0015] Optionally, a support plate is provided below the support platform, a drive motor is provided on the support plate, a drive wheel is provided on the output shaft of the drive motor, a support block is provided at the lower end of the two moving platforms, a rack is provided on one side of each of the two support blocks facing each other, and the two racks are located on both sides of the drive wheel and mesh with the drive wheel at the same time.

[0016] Optionally, the support plate is provided with a slide rail, and the lower end of the support block has a slide groove that cooperates with the slide rail. The extension direction of the slide rail is consistent with the extension direction of the rack.

[0017] Optionally, the movable platform is provided with at least two fixed blocks, each fixed block is provided with an adjusting rod, the fixed block has an adjusting hole through which the adjusting rod passes, the adjusting hole is threadedly engaged with the adjusting rod, and the end of the adjusting rod is used to abut against the main beam.

[0018] Optionally, the arrangement direction of all fixed blocks on the same moving platform is the same as the arrangement direction of all the adjustment components.

[0019] The beneficial effects that this application can achieve are:

[0020] This application discloses a welding workbench for a combined beam and base. It comprises two movable platforms, one on each side of a support platform, with a beam placed on each platform. As the two platforms move closer to the support platform, their adjustment components first contact the base. Because the distance between the two platforms and the support platform remains constant, when the contact components on the platforms are firmly against the base, the base has a symmetrical structure, and the distance from the base's centerline to the two movable platforms is also equal. This achieves automatic centering of the base, placing it in the center of the support platform. This provides precise positioning for subsequent welding of the base to the beam, eliminating the need for manual adjustment of the base's position. This reduces manual labor intensity and achieves automatic centering of the base. Attached Figure Description

[0034] Example 1

[0035] Reference Figures 1-6 The first embodiment of this application provides a workbench for welding a main beam 21 and a base 11, including: a support platform 10 for supporting the base 11; and two movable platforms 20 disposed on both sides of the support platform 10 for placing the main beam 21. Each of the two movable platforms 20 is provided with at least one adjusting component 30. The two movable platforms 20 can move in a direction close to or away from the support platform 10. The distance between the two movable platforms 20 and the support platform 10 is always equal. The adjusting component 30 can abut against the base 11 and drive the base 11 to move so that the distance between the base 11 and the two main beams 21 is equal.

[0036] In this embodiment, the support platform 10 does not have a limiting structure to restrict the left and right movement of the base 11. When the base 11 is adjusted by the adjustment component 30, the base 11 can move left and right. The width of the support platform 10 is smaller than the width of the base 11. While the support platform 10 supports the base 11, the two ends of the base 11 protrude from the left and right ends of the support platform 10. That is, when the two moving platforms 20 move towards the support platform 10, the left and right ends of the base 11 are suspended in the air. The two ends of the base 11 can move above the work surface of the moving platform 20, ensuring that the base 11 can contact the beam 21. Since the lateral width of the base 11 is greater than the width of the support platform 10, it also increases the difficulty of manually aligning the base 11 on the support platform 10. When the support platform 10 is placed on the support platform 10 by hoisting or grabbing by a robot, the centerline of the base 11 may deviate from the centerline of the support platform 10.

[0037] Specifically, by setting at least one adjustment component 30 on the moving platform 20, the adjustment components 30 on the two moving platforms 20 cooperate with each other to achieve automatic centering of the base 11 on the support platform 10. The two moving platforms 20 move synchronously to ensure that the distance between the two moving platforms 20 and the support platform 10 is always equal. As the left and right moving platforms 20 continuously move closer to the support platform 10, the adjustment components 30 first abut against the base 11. When the base 11 shifts to the left, that is, when the base 11 is closer to the left moving platform 20, the adjustment component 30 on the left abuts against the base 11 first and pushes the base 11 to the right. When the adjustment components 30 on both sides are firmly abutted against the base 11, the base 11 is ensured to be in the centerline position on the support platform 10. It should be noted that the two moving platforms 20 are symmetrically arranged with respect to the centerline of the support platform 10, and the adjustment components 30 on the two moving platforms 20 are also symmetrically arranged with respect to the centerline of the support platform 10.

[0038] Example 2

[0039] As an optional implementation method, refer to Figure 1-Figure 5 This embodiment provides a specific structure of an adjustment component 30, including: the adjustment component 30 includes a lifting block 31 and an abutment rod 32; the moving platform 20 is provided with a through hole 22 for the lifting block 31 to pass through, the through hole 22 is located between the main beam 21 and the base 11, the upper end of the lifting block 31 is provided with a receiving groove 311, the receiving groove 311 is close to the side of the support platform 10 and passes through the outer wall of the lifting block 31, the first end of the abutment rod 32 is located in the receiving groove 311, the receiving groove 311 is provided with a pin 312, the pin 312 passes through the first end of the abutment rod 32, the second end of the abutment rod 32 can rotate around the axis of the pin 312 so that the abutment rod 32 can switch between a horizontal state and a vertical state. When the abutment rod 32 is in a horizontal state, its second end can abut against the base 11. When the abutment rod 32 is in a vertical state, it can move to the bottom of the moving platform 20 through the through hole 22.

[0040] Specifically, the cross-sectional shape of the lifting block 31 can be either square or circular. The adjustment assembly 30 is located between the main beam 21 and the support platform 10. After the push base 11 is moved, the presence of the adjustment assembly 30 may interfere with the welding between the main beam 21 and the base 11.

[0041] A through hole 22 is provided on the moving platform 20, and a receiving groove 311 is provided at the upper end of the lifting block 31. The upper and right ends of the receiving groove 311 both penetrate the outer wall of the lifting block 31. The first end of the abutment rod 32 is connected to the inner wall of the receiving groove 311 through a pin 312, and the second end of the abutment rod 32 can rotate around the axis of its pin 312. When the abutment rod 32 is in a horizontal state ( Figure 2As shown), at this time, the axis of the abutment rod 32 is perpendicular to the axis of the lifting block 31, and the second end of the abutment rod 32 can abut against the base 11 to center the base 11. After the centering and adjustment of the base 11 is completed, the abutment rod 32 is driven to move, and the abutment rod 32 is adjusted to a vertical state. Figure 5 As shown), at this time, the axes of the abutment rod 32 and the lifting block 31 are parallel to each other. The lifting block 31 drives the abutment rod 32 to move downward, so that both the lifting block 31 and the abutment rod 32 can move to the bottom of the moving platform 20, ensuring that the adjustment component 30 will not affect the welding between the main beam 21 and the base 11.

[0042] Optionally, the moving platform 20 is provided with a guide groove 23, which has a guide slope 231 extending to the through hole 22, so that when the lifting block 31 moves downward, the guide slope 231 can abut against the outer wall of the abutment rod 32, guiding the abutment rod 32 from a horizontal state to a vertical state. The guide slope 231 is located between the through hole 22 and the support platform 10, and the guide slope 231 gradually slopes downward in the direction away from the support platform 10.

[0043] Specifically, by setting the guide groove 23, during the downward movement of the moving block, the guide inclined surface 231 automatically applies external force to the abutment rod 32, enabling the abutment rod 32 to automatically transition from a horizontal to a vertical state. During the downward movement of the moving block, the outer wall of the abutment rod 32 first abuts against the upper end of the guide inclined surface 231 (e.g., ...). Figure 3 As shown), during the continuous downward movement of the moving block, the outer wall of the abutment rod 32 abuts against the lower end of the guide slope 231 (as shown). Figure 4 As shown), the abutment rod 32 is finally in a vertical position. It should be noted that the vertical position is not absolutely vertical. It can also be tilted to a certain extent, but the abutment rod 32 can pass through the through hole 22 in a vertically downward direction.

[0044] Optionally, an elastic element 313 is provided at the upper end of the receiving groove 311. The elastic element 313 is located on the side of the abutment rod 32 away from the support platform 10. The elastic element 313 is used to apply a thrust to the abutment rod 32 when restoring elastic deformation.

[0045] Specifically, by setting up the elastic element 313, when the abutment rod 32 is in a vertical state, the elastic element 313 is in a state of elastic deformation, that is, when part of the abutment rod 32 is located inside the through hole 22, the elastic element 313 is in a state of elastic deformation. When the lifting block 31 moves upward, and when the abutment rod 32 is completely removed from the through hole 22, the abutment rod 32 loses the limiting effect of the inner wall of the through hole 22, the elastic element 313 restores its elastic deformation, and the elastic element 313 applies a rightward pushing force to the abutment rod 32, so that the abutment rod 32 can automatically change from a vertical state to a horizontal state. This reduces the need for manual intervention and reduces the intensity of manual labor.

[0046] Optionally, the second end of the abutment rod 32 has a threaded hole extending axially, and the threaded hole is threaded to a compensating rod 321. The distance between the end of the compensating rod 321 located outside the threaded hole and the pin 312 is adjustable.

[0047] Specifically, by screwing the compensation rod 321 in or out, the length of the abutment rod 32 can be compensated, thereby achieving overall length adjustment of the abutment rod 32 and the compensation rod 321, which can be adjusted according to actual usage needs and improve its applicability.

[0048] Optionally, a connecting plate 40 is provided below the moving platform 20. The connecting plate 40 is used to connect all the lifting blocks 31 on the same moving platform 20. The connecting plate 40 is connected to a telescopic member 41 for driving its lifting and moving.

[0049] Specifically, when there are multiple adjustment components 30 on the same moving platform 20, by adding a connecting plate 40, the connecting plate 40 is connected to all the lifting blocks 31. By controlling one lifting block 31, the lifting and moving of all the lifting blocks 31 can be realized simultaneously, so that all the lifting blocks 31 can move synchronously. It is not necessary to adjust each lifting block 31 individually, thus improving the adjustment efficiency of the lifting and moving of the lifting blocks 31.

[0050] Example 3

[0051] As an optional implementation method, refer to Figure 1 This embodiment provides a specific structure for driving the moving platform 20 to move, including: a support plate 50 is provided below the support platform 10, a drive motor 60 is provided on the support plate 50, a drive wheel 61 is provided on the output shaft of the drive motor 60, support blocks 70 are provided at the lower ends of the two moving platforms 20, and racks 62 are provided on the opposite side of the two support blocks 70. The two racks 62 are located on both sides of the drive wheel 61 and mesh with the drive wheel 61 at the same time.

[0052] Specifically, by setting the drive motor 60 and rack 62 to work together, the two moving platforms 20 can move synchronously in opposite or backward directions, which helps to control the accuracy of the distance between the two moving platforms 20 and the support platform 10.

[0053] Optionally, a slide rail 51 is provided on the support plate 50, and the lower end of the support block 70 has a slide groove that cooperates with the slide rail 51. The extension direction of the slide rail 51 is consistent with the extension direction of the rack 62.

[0054] Specifically, by setting the slide rail 51 and the slide groove to cooperate, the movement path of the moving platform 20 is assisted and guided. It should be noted that the cross-sectional shape of the slide rail 51 can be dovetail-shaped or T-shaped, and the slide groove is a dovetail groove or T-shaped groove that cooperates with the slide rail 51.

[0055] Example 4

[0056] As an optional implementation method, refer to Figure 1 and Figure 6 This embodiment provides a method including: In this embodiment, at least two fixing blocks 80 are provided on the moving platform 20, and an adjusting rod 81 is provided on the fixing block 80. The fixing block 80 has an adjusting hole through which the adjusting rod 81 passes. The adjusting hole is threadedly engaged with the adjusting rod 81, and the end of the adjusting rod 81 is used to abut against the main beam 21.

[0057] Optionally, the arrangement direction of all fixed blocks 80 on the same moving stage 20 is the same as the arrangement direction of all adjusting components 30.

[0058] In this embodiment, a fixing block 80 is provided, on which an adjustable rod 81 is provided. The adjustable rod 81 can play a role in assisting the positioning of the main beam 21. By controlling the position of the adjustable rod 81, the position of the main beam 21 on the two moving platforms 20 is ensured to be symmetrical with respect to the center line of the bearing platform 10. During the movement of the moving platform 20, the adjusting component 30 first centers the base 11. After centering, the moving platform 20 can move backward a certain distance. Then, the lifting block 31 moves downward, driving the abutment rod 32 to move downward as well. When the lifting block 31 and the abutment rod 32 move below the moving platform 20, the moving platform 20 continues to move towards the bearing platform 10 until the main beam 21 abuts against the base 11. Then, the workers weld the main beam 21 and the base 11.

[0059] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
