[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The adjustment structure 2 includes a connecting plate 201, which is fixedly connected to the base plate 1. An electric actuator 202 is fixedly connected to one side of the connecting plate 201. Two sliding grooves 203 are formed on the upper surface of the base plate 1. Two sliders 204 are slidably connected to the inner walls of each of the two sliding grooves 203. A common connecting plate 205 is fixedly connected to the upper surface of each slider 204. The connecting plate 205 is fixedly connected to the output end of the electric actuator 202. A rack 206 is fixedly connected to one side of the connecting plate 205. A gear 207 is rotatably connected to the upper surface of the base plate 1, and the gear 207 meshes with the rack 206. Several springs 208 are fixedly connected to one side of the connecting plate 205, and limit blocks 209 are fixedly connected to one side of each spring 208. By setting the adjustment structure 2, parts of different sizes and shapes can be clamped and limited, thereby achieving height adjustment. The adaptability and flexibility of the fixture enable it to process multiple types of parts on the same equipment, increasing its production efficiency. Several telescopic rods 211 are fixedly connected to one side of the connecting plate 205. The telescopic rods 211 and the limiting block 209 are fixedly connected. The telescopic rods 211 can support the spring 208 and prevent the spring 208 from shifting left and right during use. The inner wall of the slide 203 is fixedly connected to the limiting rod 212. The limiting rod 212 is slidably connected to the slider 204. The limiting rod 212 can limit the slider 204 and prevent the slider 204 from shifting during movement. A soft pad 210 is fixedly connected to one side of the limiting block 209. The soft pad 210 is a rubber pad. The soft pad 210 can prevent the limiting block 209 from directly contacting the parts, thus preventing the parts from wearing out.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary structure 3 includes a fixing block 31, which is fixedly connected to both sides of the base plate 1. A connecting groove 32 is formed on the upper surface of the fixing block 31, and a positioning post 36 is slidably connected to the inner wall of the connecting groove 32. An auxiliary plate 33 is fixedly connected to one side of the fixing block 31, and a servo motor 34 is fixedly connected to one side of the auxiliary plate 33. A screw 35 is fixedly connected to the output end of the servo motor 34, and the screw 35 is rotatably connected to the inner wall of the connecting groove 32. The screw 35 is threadedly connected to the positioning post 36, and a limit plate 37 is fixedly connected to one side of the positioning post 36. By setting the auxiliary structure 3, further...

[0036] The working principle of the multifunctional jig for assembling automotive parts provided by this utility model is as follows: By setting the adjustment structure 2, the electric push rod 202 on one side of the connecting plate 201 is first activated, causing the electric push rod 202 to push the connecting plate 205 to move. The connecting plate 205 then drives the slider 204 to move within the slide groove 203 of the base plate 1. When the connecting plate 205 moves, it also drives the rack 206 to move. When the rack 206 moves, it drives the gear 207 to rotate. The gear 207 then drives another rack 206 to move, causing the two connecting plates 205 to move in the same direction until the spring 208... The limiting block 209 on the side clamps the component. When the limiting block 209 contacts the component, the spring 208 will extend or retract, allowing it to clamp components of different shapes. The telescopic rod 211 can support the spring 208 and prevent the spring 208 from shifting left or right during use. The limiting rod 212 can limit the slider 204 and prevent the slider 204 from shifting during movement. The soft pad 210 can prevent the limiting block 209 from directly contacting the component, thus preventing wear on the component.

[0037] By setting up auxiliary structure 3, the servo motor 34 on one side of auxiliary plate 33 is first started, causing the servo motor 34 to drive the screw 35 to rotate. When the screw 35 rotates, it will drive the positioning post 36 to move in the connecting groove 32 of the fixed block 31. When the positioning post 36 moves, it will drive the limiting plate 37 to move, so that the limiting plate 37 clamps and limits the parts. The protective cover 38 can protect the servo motor 34 and prevent dust from entering the inside of the servo motor 34. The ball bearing 39 can reduce the friction of the positioning post 36, so that the positioning post 36 can move more smoothly in the connecting groove 32.
