Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically a welding fixture that can be used for multiple vehicle models. Background Technology

[0002] Welding fixtures are core specialized tooling used in welding production to ensure workpiece dimensional accuracy and suppress welding deformation. By positioning, clamping, and supporting the workpiece during the welding process, they directly guarantee production quality and efficiency, making them an indispensable key piece of equipment, especially in the automotive parts processing industry.

[0003] In current technologies, automotive welding fixtures typically employ multiple sets of cylinders to drive clamping plates in a coordinated manner to ensure the vehicle body is securely fixed to the welding platform. The arrangement of the clamping plates needs to be preset according to the structural parameters of a specific vehicle model to meet the stability requirements of the welding process.

[0004] However, such welding fixtures have obvious limitations: their fixing cylinders are mostly rigidly connected to the support frame by bolts, which can only be adapted to a single vehicle model. If it is necessary to switch to other vehicle models, the cylinders need to be manually disassembled and the installation position readjusted. The whole operation process is cumbersome and time-consuming, which greatly reduces the versatility and production practicality of the fixture. Therefore, a welding fixture that can be used for multiple vehicle models is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a welding fixture that can be used by multiple vehicle models.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a welding fixture for multiple vehicle models, including a base plate, a rectangular frame fixedly connected to the top of the base plate, a slider slidably connected to the outer wall of the rectangular frame, a rectangular shell fixedly connected to the side wall of the slider, a sliding plate slidably connected to the inner wall of the rectangular shell, a support block fixedly connected to the end side of the sliding plate, a cylinder fixedly installed on the side wall of the support block, a clamping plate fixedly connected to the top side of the cylinder, a cylinder fixedly connected to the bottom side of the end of the clamping plate, a rubber pressure block sleeved on the outer wall of the bottom of the cylinder, a limit component provided on the inner wall of the rectangular shell, the limit component including a threaded rod, the threaded rod being threadedly connected to the inner wall of the rectangular shell, a friction block being rotatably connected to the top of the threaded rod, a rectangular groove being opened on the inner wall of the rectangular shell, the outer wall of the friction block being slidably connected to the inner wall of the rectangular groove, a friction pad being fixedly connected to the inner wall of the sliding plate, and the top side of the friction block contacting the bottom side of the friction pad.

[0007] Preferably, the inner wall of the cylinder is elastically connected to a push block by a spring, the outer wall of the push block is slidably connected to the inner wall of the cylinder, one end of the spring is fixedly connected to the inner wall of the cylinder, the other end of the spring is fixedly connected to the side wall of the push block, a connecting plate is fixedly connected to the bottom side of the push block, the connecting plate is slidably connected to the inner wall of the cylinder, a locking block is fixedly connected to the bottom side of the connecting plate, and a locking groove is opened on the inner wall of the rubber pressure block, and the locking block is inserted into the inner wall of the locking groove.

[0008] Preferably, the limiting component further includes a rectangular plate that slides on the bottom side of the rectangular shell. A connecting plate is rotatably connected to one end of the rectangular plate, and a hinge block is rotatably connected to the other end of the connecting plate. The outer wall of the end of the threaded rod is rotatably connected to the inner wall of the hinge block. Two sets of friction pads and friction blocks are provided. One set of friction pads is fixed to the side wall of the rectangular frame, and the other set of friction blocks is fixed to the end of the rectangular plate.

[0009] Preferably, a groove is provided on the bottom side of the rectangular shell, and a movable block is slidably connected to the inner wall of the groove. The bottom side of the movable block is fixed to the top side of the rectangular plate.

[0010] Preferably, the push block, connecting plate, locking block, spring, and locking groove are provided in multiple sets, and the multiple sets of push blocks, connecting plates, locking blocks, springs, and locking grooves are symmetrically arranged with the center line of the cylinder as the axis of symmetry.

[0011] Preferably, the end face of the card block is set as an inclined surface.

[0012] Preferably, multiple sets of sliders, rectangular shells, sliding plates, support blocks, cylinders, and clamping plates are provided, and these multiple sets of sliders, rectangular shells, sliding plates, support blocks, cylinders, and clamping plates are arranged in a rectangular frame shape.

[0013] The advantages of this utility model are: by cooperating with the slider, rectangular shell, sliding plate and limiting component, the positions of the support block, cylinder, clamp, cylinder and rubber pressure block that fix and support the vehicle body can be adjusted at will, so that the welding fixture can be adapted to different vehicle models, improving convenience and adaptability.

[0014] This invention controls the rotation of the threaded rod in the limiting assembly, simultaneously releasing the limiting structure on the slider and the slide plate. This allows the support block to be pulled, changing the connection distance between the slide plate and the rectangular shell, or the rectangular shell to be pushed, causing the slider to move on the outer wall of the rectangular frame. Once the adjustment is complete, the limiting assembly can be used to limit the position, achieving the effect of quickly adjusting the position of the support block, cylinder, clamping plate, cylinder, and rubber pressure block. This solves the problem that when some welding fixtures are switched to other vehicle models, it is necessary to manually disassemble the cylinder and readjust the installation position, which is cumbersome and time-consuming, significantly reducing the versatility and production practicality of the fixture.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail. This application discloses a welding fixture that can be used by multiple vehicle models. (Refer to...) Figure 1 - Figure 3 and Figure 5A welding fixture for multiple vehicle models includes a base plate 1, a rectangular frame 2 fixedly connected to the top of the base plate 1, a slider 3 slidably connected to the outer wall of the rectangular frame 2, a rectangular shell 4 fixedly connected to the side wall of the slider 3, a sliding plate 5 slidably connected to the inner wall of the rectangular shell 4, a support block 6 fixedly connected to the end of the sliding plate 5, a cylinder 7 fixedly mounted on the side wall of the support block 6, a clamping plate 8 fixedly connected to the top of the cylinder 7, a cylinder 10 fixedly connected to the bottom of the end of the clamping plate 8, a rubber pressure block 11 sleeved on the outer wall of the bottom of the cylinder 10, and a limit component provided on the inner wall of the rectangular shell 4. The system includes a threaded rod 9, which is threaded to the inner wall of a rectangular shell 4. A friction block 97 is rotatably connected to the top of the threaded rod 9. A rectangular groove 12 is formed on the inner wall of the rectangular shell 4. The outer wall of the friction block 97 is slidably connected to the inner wall of the rectangular groove 12. A friction pad 96 is fixed to the inner wall of the slide plate 5. The top side of the friction block 97 contacts the bottom side of the friction pad 96. During operation, the car body to be welded is placed on the rectangular frame 2, ensuring that the main support fixing point is placed on the top side of the support block 6. Then, the cylinder 7 is activated to move the clamping plate 8. When the clamping plate 8 moves, it drives the cylinder 10 and the rubber pressure block 11 to move, fixing the main points of the vehicle body. When it is necessary to adjust the position of the support block 6, cylinder 7 and clamping plate 8 according to the vehicle model, the threaded rod 9 can be rotated. At this time, the threaded rod 9 will drive the friction block 97 to slide on the inner wall of the rectangular groove 12, so that the friction block 97 is disengaged from the friction pad 96, releasing the limit on the slide plate 5. In conjunction with the cooperation of other structures in the upper limit assembly, the limit on the slider 3 can be released at the same time. In this way, the connection distance between the slide plate 5 and the rectangular shell 4 can be adjusted, and the position of the slider 3 on the rectangular frame 2 can also be flexibly adjusted, improving convenience. After the adjustment is completed, rotate the threaded rod 9 to make the friction block 97 and the friction pad 96 fit together. Through the friction between the friction block 97 and the friction pad 96, the slide plate 5 can be limited. Through the above operations, it can be ensured that the welding fixture can flexibly adjust the position of the support block 6, cylinder 7 and clamping plate 8 when facing different vehicle models, without the need for disassembly adjustment, thus improving the convenience of operation.

[0020] Reference Figure 4 and Figure 6A push block 13 is elastically connected to the inner wall of the cylinder 10 via a spring 16. The outer wall of the push block 13 is slidably connected to the inner wall of the cylinder 10. One end of the spring 16 is fixed to the inner wall of the cylinder 10, and the other end of the spring 16 is fixed to the side wall of the push block 13. A connecting plate 14 is fixedly connected to the bottom side of the push block 13, and the connecting plate 14 is slidably connected to the inner wall of the cylinder 10. A locking block 15 is fixedly connected to the bottom side of the connecting plate 14. A locking groove 17 is opened on the inner wall of the rubber pressure block 11, and the locking block 15 is inserted into the inner wall of the locking groove 17. During operation, the rubber pressure block 11 directly contacts the vehicle body, which can reduce the vehicle's speed. To mitigate the risk of wear and tear, when the rubber pressure block 11 is damaged and needs replacement, the push block 13 can be pushed to compress the spring 16, simultaneously moving the connecting plate 14 and the locking block 15. This causes the locking block 15 to disengage from the inner wall of the slot 17, allowing the rubber pressure block 11 to be removed. During installation, the rubber pressure block 11 is directly fitted onto the inner wall of the cylinder 10. After fitting, the locking block 15 will be stably inserted into the inner wall of the slot 17 by the elasticity of the spring 16. Compared to the traditional bolt-fixing method, this improves the efficiency of maintenance and replacement.

[0021] Reference Figure 2 - Figure 3 The limiting component also includes a rectangular plate 92, which slides on the bottom side of the rectangular shell 4. A connecting plate 91 is rotatably connected to one end of the rectangular plate 92, and a hinge block 93 is rotatably connected to the other end of the connecting plate 91. The outer wall of the end of the threaded rod 9 is rotatably connected to the inner wall of the hinge block 93. Two sets of friction pads 96 and friction blocks 97 are provided. The other set of friction pads 96 is fixed to the side wall of the rectangular frame 2, and the other set of friction blocks 97 is fixed to the end of the rectangular plate 92. When the limiting component is in use, the moving threaded rod 9 will drive the hinge block 93 to move. The hinge block 93 will rotate with the end of the connecting plate 91, and the angle of the connecting plate 91 will change. The other end of the connecting plate 91 will rotate with the rectangular plate 92, and drive the rectangular plate 92 to move, so that the rectangular plate 92 will drive the other set of friction blocks 97 to disengage from the other set of friction pads 96. In this way, the limiting of the slide plate 5 and the slider 3 can be released at the same time, improving convenience.

[0022] Reference Figure 3 The rectangular shell 4 has a sliding groove 95 on its bottom side. A movable block 94 is slidably connected to the inner wall of the sliding groove 95. The bottom side of the movable block 94 is fixed to the top side of the rectangular plate 92. When the rectangular plate 92 moves, it will move the movable block 94 to slide on the inner wall of the sliding groove 95. Through the cooperation between the movable block 94 and the sliding groove 95, the rectangular plate 92 can move horizontally stably.

[0023] Reference Figure 4 and Figure 6Multiple sets of push blocks 13, connecting plates 14, locking blocks 15, springs 16, and locking slots 17 are provided, and these multiple sets of push blocks 13, connecting plates 14, locking blocks 15, springs 16, and locking slots 17 are symmetrically arranged with the center line of cylinder 10 as the axis of symmetry. During operation, the cooperation of the multiple sets of push blocks 13, connecting plates 14, locking blocks 15, springs 16, and locking slots 17 can further improve the stability of the rubber pressure block 11 installation.

[0024] Reference Figure 6 The end of the locking block 15 is set with a slope. During operation, the slope ensures that the position of the locking block 15 does not need to be manually controlled when installing the rubber pressure block 11, thus improving the convenience of installation.

[0025] Reference Figure 1 The welding fixture has multiple sets of slider 3, rectangular shell 4, sliding plate 5, support block 6, cylinder 7, and clamping plate 8. These multiple sets of slider 3, rectangular shell 4, sliding plate 5, support block 6, cylinder 7, and clamping plate 8 are arranged in a rectangular frame 2. During operation, the welding fixture can simultaneously fix different units of the car body by cooperating with the multiple sets of slider 3, rectangular shell 4, sliding plate 5, support block 6, cylinder 7, and clamping plate 8, ensuring the stability of the welding.

[0026] Working principle: By placing the car body to be welded on the rectangular frame 2 and ensuring that the main support fixing points are placed on the top side of the support block 6, the cylinder 7 is then started to drive the clamping plate 8 to move. The clamping plate 8 will drive the cylinder 10 and the rubber pressure block 11 to move, thereby fixing the main points of the car body.

[0027] When the positions of the support block 6, cylinder 7, and clamping plate 8 need to be adjusted according to the vehicle model, the threaded rod 9 can be rotated. This causes the threaded rod 9 to slide the friction block 97 against the inner wall of the rectangular groove 12, disengaging the friction block 97 from the friction pad 96 and releasing the restriction on the sliding plate 5. Simultaneously, the moving threaded rod 9 causes the hinge block 93 to move, rotating with the end point of the connecting plate 91 and changing the angle of the connecting plate 91. The other end of the connecting plate 91 rotates with the rectangular plate 92, causing the rectangular plate 92 to move, thus moving another set of friction blocks 97 against another... When the friction pad 96 is disengaged, the limiting position of the slider 3 can be released simultaneously. This allows adjustment of the connection distance between the slide plate 5 and the rectangular shell 4. The position of the slider 3 on the rectangular frame 2 can also be flexibly adjusted, improving convenience. After adjustment, the threaded rod 9 is rotated in the opposite direction to make the friction block 97 and the friction pad 96 fit together. Through the friction between the friction block 97 and the friction pad 96, the slide plate 5 can be limited. Through the above operations, it can be ensured that the welding fixture can flexibly adjust the positions of the support block 6, cylinder 7 and clamping plate 8 when facing different vehicle models, without the need for disassembly, thus improving the convenience of operation.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
