[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] like Figure 1-4 As shown, this utility model embodiment provides a modular car rear cover clamp, including a clamp base 1, a positioning module, and a clamping module. The positioning module includes a positioning seat 4 and a fixing device, which includes a positioning pin 5, a fixing post 7, a rotating block 8, a shaft 9, and a cross plate 10; the clamping module is mounted on an adjusting frame 16 and includes a clamping cylinder 11, a clamping arm 13, and a clamping block 14.

[0018] The fixture base 1, as the basic support component of the entire fixture, possesses sufficient strength and stability to withstand various forces exerted during the processing or assembly of the car rear cover. The fixture base 1 is detachably connected to the positioning module and clamping module: both the positioning seat 4 and the adjusting bracket 16 have multiple mounting plates 2 parallel to the fixture base at their bottoms. Connecting bolts 3 are inserted into the corresponding connecting holes on the mounting plates 2 and the fixture base, enabling the positioning module and clamping module to be connected perpendicularly to the fixture base 1.

[0019] The positioning module is used to precisely position the car rear cover, ensuring its accurate position on the fixture. The positioning seat 4 has multiple parallel positioning holes 6 on its surface. The fixing post 7 and rotating block 8 in the fixing device are adapted to the shapes of the positioning holes 6. The fixing post 7 is fixedly connected to one side of the horizontal plate 10, and the rotating block 8 is fitted onto the shaft 9 and can rotate axially around the shaft 9, arranged coaxially with the fixing post 7. The positioning pin 5 is installed on the other side of the horizontal plate 10, and its shape can be one or more of cylindrical, rhomboid, or square shapes depending on the material's shape, to achieve positioning of car rear covers of different shapes and sizes.

[0020] The clamping module is used to reliably clamp the positioned car rear cover, preventing displacement during processing or assembly. Mounting holes 17 are arranged on both sides of the adjusting frame 16. The surface of the clamping cylinder 11 is provided with an external threaded bracket 18 that matches the mounting holes 17, and the body is connected to an external air source via an air pipe 19. The clamping cylinder 11 includes a piston rod 12, with one end of the clamping arm 13 connected to the piston rod 12 and the other end connected to the clamping block 14. The shape of the clamping block 14 is selected according to the material shape, choosing a flat or curved shape. An anti-slip rubber pad 15 is installed at the front end to increase clamping force and prevent damage to the surface of the car rear cover. When the clamping cylinder 11 is ventilated, the piston rod 12 extends or retracts, driving the clamping arm 13 to extend and retract back and forth, causing the clamping block 14 to clamp or release the car rear cover.

[0021] Working principle: According to the positioning and clamping requirements of different car models' rear covers, the user first selects positioning pins 5 of different sizes and shapes. The positioning seat 4 and the adjusting frame 16 are installed on the clamp base 1 through the connecting bolt 3. The positioning pin 5 is installed on the horizontal plate 10 of the fixing device. According to the required height, the fixing post 7 is inserted into the positioning hole 6 on the positioning seat 4. The rotating block 8 is twisted so that the rotating block 8 cannot pass through the positioning hole 6, thus fixing the positioning pin 5. The positioning hole of the car rear cover is aligned with the positioning pin 5 and inserted to complete the positioning. Then, the size and shape of the clamping block 14 are selected. The anti-slip rubber pad 15 is installed on the front end of the clamping block 14. The clamping arm 13 and the piston rod 12 are connected to the clamping cylinder 11. According to the required height, the clamping cylinder 11 is connected to the adjusting frame 16 through the mounting hole 17 through the external threaded bracket 18 on the surface, and then fixed to the clamp base 1. Finally, the clamping cylinder 11 is activated, the piston rod 12 drives the clamping arm 13 to extend forward, and the clamping block 14 clamps the car rear cover, allowing the workers to carry out subsequent processing, assembly and other operations; after the operation is completed, the clamping cylinder 11 is closed, the clamping block 14 is released, the positioning module and clamping module are disassembled, and it is ready for the next use.
