Description

Technical Field

[0001] This utility model relates to the field of vehicle body welding technology, and in particular to a welding fixture for all-terrain vehicle bodies. Background Technology

[0002] An all-terrain vehicle is a light vehicle designed for off-road driving, possessing off-road capability and mobility. It can travel on various complex terrains without being limited by road conditions.

[0003] During the full welding process of the all-terrain vehicle body, the large size of the entire vehicle body and the numerous weld seams make positioning and clamping during welding difficult, resulting in a low rate of weldable positions and low welding efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a welding fixture for all-terrain vehicle bodies, which solves the problem of low welding efficiency in the existing technology during the full welding process of all-terrain vehicle bodies. Due to the large overall size of the vehicle body, the number of welds, and the large size of the vehicle body, it is difficult to position and clamp during welding, resulting in a low rate of weldable positions and low welding efficiency.

[0005] To achieve the above objectives, this utility model provides an all-terrain vehicle body welding fixture, including a fixture, multiple mounting seats, multiple side clamping mechanisms, and a bottom clamping mechanism. Each side clamping mechanism includes a centering clamping unit, two side uprights, a rotating handwheel, a lead screw, a guide seat, two limiting grooves, a movable pressure plate, a first locking pin, and a second locking pin. The multiple mounting seats are respectively disposed on the upper end of the fixture, and the multiple side clamping mechanisms are respectively disposed on the sides of the fixture. The two side uprights are respectively fixedly connected to the sides of the fixture. The guide seat is disposed on the upper end of the two side uprights. One end of the lead screw is disposed inside the guide seat. The rotating handwheel is fixedly connected to the lead screw and located outside the guide seat. The first locking pin and the second locking pin are respectively disposed on the guide seat. The two limiting grooves are respectively disposed on the corresponding side uprights, and the two limiting grooves are respectively slidably adapted to the movable pressure plate.

[0006] The bottom clamping mechanism includes a positioning pin, multiple first clamping plates, multiple second clamping plates, and two first locking nuts. The positioning pin is disposed on the corresponding mounting base, and the multiple first clamping plates and multiple second clamping plates are respectively symmetrically disposed on the mounting base.

[0007] Two locking nuts are respectively disposed on the corresponding mounting bases, and the two locking nuts are respectively located at the upper ends of the corresponding first pressing plate and the corresponding second pressing plate. Multiple first pressing plates and multiple second pressing plates are respectively disposed on the centering pressing unit.

[0008] The centering and clamping unit includes a second locking bolt and a side clamping plate. The side clamping plate is detachably connected to the movable pressure plate. One end of the second locking bolt passes through the second clamping plate and is located inside the movable pressure plate. Multiple first clamping plates and multiple second clamping plates are detachably connected to the side clamping plate respectively.

[0009] This utility model discloses an all-terrain vehicle body welding fixture. The vehicle body is placed on the fixture. Before full welding, during assembly, the rotating handwheel is turned, causing the lead screw to rotate. The lead screw then pushes the movable pressure plate, thereby moving the vehicle body to the welding position. The movable pressure plate moves within two limiting grooves. Then, the first and second locking pins are inserted downwards to lock the guide rod inside the guide seat, preventing it from loosening. This allows for convenient and accurate positioning of the entire vehicle body to the welding position, ensuring reliable clamping, a high weldability rate, and easy disassembly of the vehicle body after welding.

[0018] This utility model provides an all-terrain vehicle body welding fixture 1, including a fixture 1, multiple mounting seats 2, multiple side clamping mechanisms, and a bottom clamping mechanism. Each side clamping mechanism includes a centering clamping unit, two side uprights 3, a rotating handwheel 4, a lead screw 5, a guide seat 6, two limiting grooves 7, a movable pressure plate 8, a first locking pin 9, and a second locking pin 10. The multiple mounting seats 2 are respectively disposed on the upper end of the fixture 1, and the multiple side clamping mechanisms are respectively disposed on the side of the fixture 1. The two side uprights 3 are respectively fixedly connected to the side of the fixture 1. The guide seat 6 is disposed on the upper end of the two side uprights 3. One end of the lead screw 5 is disposed inside the guide seat 6. The rotating handwheel 4 is fixedly connected to the lead screw 5 and is located outside the guide seat 6. The first locking pin 9 and the second locking pin 10 are respectively disposed on the guide seat 6. The two limiting grooves 7 are respectively disposed on the corresponding side uprights 3, and the two limiting grooves 7 are respectively slidably adapted to the movable pressure plate 8.

[0019] In this embodiment, the car body is placed on the fixture 1. When assembling the car body before full welding, the rotating handwheel 4 is turned to drive the lead screw 5 to rotate. The lead screw 5 pushes the moving pressure plate 8 to move, thereby pushing the car body to the welding position. The moving pressure plate 8 moves within the two limiting grooves 7. Then, the first locking pin 9 and the second locking pin 10 are inserted downwards to lock the guide rod inside the guide seat 6 and prevent it from loosening. This allows the entire car body to be conveniently and accurately positioned at the welding position, ensuring reliable clamping, a high weldability rate, and easy disassembly of the car body after welding.

[0020] Furthermore, the bottom clamping mechanism includes a positioning pin 11, a plurality of first clamping plates 12, a plurality of second clamping plates 13, and two first locking nuts 14.

The plurality of first clamping plates and the plurality of second clamping plates are respectively disposed on the centering clamping unit.

[0021] In this embodiment, when assembling the car body before full welding, the car body is first initially positioned using the positioning pin 11. After the lead screw 5 pushes the car body to the welding position, it then pushes multiple first clamping plates 12 and multiple second clamping plates 13 to press the car body together. The multiple first clamping plates 12 and multiple second clamping plates 13 are pressed together by two first locking nuts 14 to prevent loosening, thereby clamping.

[0022] Furthermore, the centering and clamping unit includes a second locking bolt 15 and a side clamping plate 16. The side clamping plate 16 is detachably connected to the movable clamping plate 8. One end of the second locking bolt 15 passes through the second clamping plate 13 and is located inside the movable clamping plate 8. A plurality of first clamping plates 12 and a plurality of second clamping plates 13 are detachably connected to the side clamping plate 16 respectively.

[0023] In this embodiment, the side clamping plate 16 is locked by the second locking bolt 15 to prevent loosening, thereby completing the clamping operation.
