[0030] In an embodiment of this utility model, in order to clamp and fix the automotive parts, specifically, the sliding component 4 includes a slide groove 41, which is opened on the top of the fixed plate 2. The inner wall of the slide groove 41 is slidably connected to a slider 42, a first movable plate 43, and a second movable plate 45. The first movable plate 43 is fixedly connected to the top of the slider 42, and a clamping block 44 is fixedly connected to the top of the first movable plate 43. The second movable plate 45 is fixedly connected to the bottom of the slider 42. The driving component 5 includes an electric push rod 51, which is installed on the outer wall of the fixed block 3. The output end of the electric push rod 51 is connected to a connecting block 52. A straight rod 53 is hinged to the right side of the connecting block 52. A triangular plate 54 is fixedly connected to the outer wall of the straight rod 53, and a vertical plate 55 is fixedly connected to the right side of the triangular plate 54.

[0031] Furthermore, the top of the vertical plate 55 is fixedly connected to the bottom of the movable plate 45, and a connecting rod 56 is hinged to the bottom of the movable plate 45. A movable plate 57 is hinged to the end of the connecting rod 56 away from the movable plate 45. A movable groove 61 is provided on the outer wall of the column 6, and the movable plate 57 is rotatably connected to the inner wall of the movable groove 61.

[0032] Furthermore, the side fixing assembly 7 includes a chassis 71, which is fixedly connected to the top of the workbench 1. A column 72 is fixedly connected to the top of the chassis 71. A movable column 73 is movably connected to the outer wall of the column 72. A straight plate 74 is hinged to the top of the movable column 73. A vertical rod 75 is movably connected to the end of the straight plate 74 away from the movable column 73. The vertical rod 75 movably passes through the straight plate 74 and extends upward. A pressure plate 76 is fixedly connected to the bottom of the vertical rod 75. A pin 77 is inserted into the outer wall of the column 72. The side of the automotive parts is fixed by the side fixing assembly 7. The movable column 73 and the chassis 71 are elastically connected by a spring. The top of the pressure plate 76 and the straight plate 74 are elastically connected by a spring.

[0033] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. For example, the electric actuator 51 is connected to the mains power. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0034] In this invention, during use, the electric actuator 51 extends, causing the connecting block 52 to move to the right. The connecting block 52 pushes the hinged straight rod 53, which in turn causes the triangular plate 54 and the vertical plate 55 to move to the right, thereby moving the second movable plate 45. The second movable plate 45 then drives the first movable plate 43 to slide within the slide groove 41 via the slider 42. During this process, the connecting rod 56 hinged at the bottom of the second movable plate 45 moves with the second movable plate 45, causing the movable plate 57 to rotate within the movable groove 61, thus enabling the four second movable plates 45 to move outward. Since there are four sets of sliding components 4, each set is located at one of the four corners of the fixed plate 2, the four sets of sliding components... Component 4 moves synchronously, causing the clamping block 44 mounted on top of the movable plate 43 to move outward. At this time, the automotive part is placed on the fixed plate 2, and the electric push rod 51 retracts, causing the clamping block 44 to contact the automotive part and clamp it, achieving initial positioning and fixation of the automotive part. After the initial clamping of the automotive part is completed, the side fixing component 7 further fixes the side of the automotive part. The movable column 73 is manually moved downward to retract the spring. After the pressure plate 76 is pressed tightly against the surface of the automotive part, the spring at the top of the pressure plate 76 retracts. At this time, the pin 77 is inserted into the outer wall of the column 72 to fix the position of the movable column 73 and prevent the automotive part from shaking. After the automotive part is stably fixed by the clamping block 44 and the side fixing component 7, the welding arm 8 is activated. The welding arm 8 moves to the part of the automotive part that needs to be welded and performs the welding work.
