[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] like Figure 1-4 As shown: This embodiment provides an automobile parts welding fixture, including a welding frame 100 and a clamping assembly, the top of the welding frame 100 is provided with a plurality of array-arranged slots 112, both sides of the top of the welding frame 100 are fixedly connected with a plurality of limit columns 101, the top center of the limit column 101 is fixedly connected with a sliding column 102, the tops of the sliding columns 102 on the same side are fixedly connected with the same limit plate 103, the limit plate 103 and the welding frame 100 are rotatably connected with a screw rod 104, the middle part of the screw rod 104 is threadedly connected with the same welding plate 105, the four corners of the welding plate 105 are slidably connected with the adjacent sliding columns 102, the middle part of the welding plate 105 is provided with a rotation groove 106, the rotation groove 106 ... A clamping assembly is provided in the middle of the groove 106, and the clamping assembly includes a welding disc 201, a bidirectional screw rod 202, a clamping plate 203 and a limit block 204. The welding disc 201 is rotatably connected to the center of the bottom wall of the rotating groove 106. A groove is provided in the middle of the welding disc 201, and the groove is rectangular. The middle of the groove is rotatably connected to the bidirectional screw rod 202. Both ends of the bidirectional screw rod 202 are threadedly connected to the clamping plates 203. The bottom of the clamping plates 203 is slidably connected to the groove. The opposite inner sides of the two clamping plates 203 are bolted to the limit block 204. Knobs 205 are fixedly connected to both sides of the bidirectional screw rod 202. Avoidance grooves are provided at both ends of the welding disc 201. The knobs 205 are located in the middle of adjacent avoidance grooves.

[0024] The automobile parts are placed in the middle of the welding pad 201, and then the two-way screw rod 202 is rotated by twisting the knob 205, so that the two clamping plates 203 move toward the middle of the two-way screw rod 202 under the limit of the groove, driving the limit block 204 to move, so that the limit block 204 contacts and clamps the automobile parts. The avoidance groove can avoid the collision between the knob 205 and the welding plate 105 during subsequent processing. The limit block 204 can be replaced by bolts so that it can clamp different automobile parts. After clamping, the two screw rods 104 are driven to rotate synchronously, so that the welding plate 105 is displaced up and down under the limit of the sliding column 102. The limit plate 103 prevents the screw rod 104 from excessively rotating so that the welding plate 105 is separated from the screw 104 and causes an accident. The limit column 101 The bottom height of the limiting welding plate 105 is prevented to prevent the welding pad 201 from excessive displacement and collision with the welding frame 100. The vertical position of the welding plate 105 can be accurately controlled by the screw 104, so that the automobile parts can be more flexibly welded at different positions with the welding gun during the welding process. By rotating the welding pad 201, the automobile parts can be rotated with the welding pad 201 as the center, further expanding the welding range and improving flexibility. The notch 112 can effectively prevent welding slag from accumulating and affecting the construction environment. At the same time, a large number of notches 112 can effectively reduce the equipment quality and reduce production costs. The bidirectional screw 202 effectively positions the accessories, and the screw 104 and the welding pad 201 can realize multi-angle and multi-directional welding of automobile accessories.

A rotating motor 111 is fixedly connected to the bottom of the welding plate 105, and the output shaft of the rotating motor 111 is fixedly connected to the bottom center of the welding pad 201, and the input end of the rotating motor 111 is electrically connected to the output end of the control panel 107;

[0027] The operation of the lifting motor 108 is controlled by the control panel 107. The lifting motor 108 drives the screw 104 on one side to rotate, so that the screw 104 drives the adjacent sprocket 109 to rotate synchronously. The chain 110 can drive the sprocket 109 and the screw 104 on the other side to rotate synchronously, and finally the two screws 104 are electrically driven to rotate synchronously, so that the welding plate 105 can rise and fall smoothly. The operation of the rotating motor 111 is controlled by the control panel 107. The output shaft of the rotating motor 111 drives the adjacent welding plate 105 to rotate, thereby adjusting the angle of the accessories. The rise and fall and rotation of the welding pad 201 can be flexibly and conveniently controlled by the control panel 107.

[0028] Working principle:

[0029] Place the auto parts in the middle of the welding pad and clamp them with a bidirectional screw rod and a clamping plate. Start the lifting motor through the control panel to raise the welding plate to the welding position. At the same time, adjust the angle of the welding pad through the rotating motor to meet the welding requirements. Start the welding equipment for welding.
