[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as Figures 1-7 As shown, this utility model provides a welding fixture for a car rear suspension arm, including a fixture body 1, a control arm 101, a fixing component, and a heat dissipation component; The control arm 101 is disposed on the top of the tooling body 1 so as to clamp and fix the control arm 101 through the tooling body 1. In addition, the fixing components include: a clamping member 102 is fixedly installed on the top right side of the tooling body 1, and an electric push rod 103 is fixedly installed inside the clamping member 102. In this design, the electric push rod 103 can realize automated control to reduce the cumbersome operation of personnel. A pushing member 104 is fixedly installed on the top of the electric push rod 103. The pushing member 104 is slidably connected inside the clamping member 102. Multiple connecting posts 105 are movably embedded inside the clamping member 102. Push blocks 106 are fixedly installed on opposite sides of multiple connecting columns 105. In this design, push blocks 106 are fixedly installed on opposite sides of connecting columns 105 to ensure the stability of push blocks 106 and prevent the displacement of the thrust. Multiple sliders 107 are fixedly installed on the top of push member 104. The interior of multiple push blocks 106 is provided with a first slide groove 108. Multiple sliders 107 are slidably connected to the inner surface of the first slide groove 108. The cooperation between sliders 107 and the first slide groove 108 forms a precise guide to effectively avoid lateral displacement. A first clamping plate 109 is fixedly installed on opposite sides of multiple connecting columns 105. Multiple first clamping plates 109 are slidably connected inside the clamping member 102. Each of the multiple first clamping plates 109 has a return spring 110 fixedly installed on one side opposite to the first clamping plate 109. In this design, when the external force disengages from the first clamping plate 109, the return spring 110 will automatically restore the first clamping plate 109 to its original position. The other ends of the multiple return springs 110 are fixedly installed on the outer surface of the clamping member 102. The tooling body 1 has a screw 111 threadedly connected to the left side of the interior. A crank 112 is fixedly installed on the left side of the screw 111. In this design, the screw 111, in cooperation with the crank 112, can precisely control the movement of the second clamping plate 113 by rotating the crank 112. The second clamping plate 113 is movably connected to the right side of the screw 111. A second sliding groove 115 is provided on the top side of the interior of the tooling body 1. The second clamping plate 113 is slidably connected to the inner surface of the second sliding groove 115. The outer surfaces of the second clamping plate 113 and the multiple first clamping plates 109 are all provided with soft pads 114. The soft pads 114 can buffer the direct contact between the clamping plate and the control arm 101, and avoid damage or deformation of the surface of the control arm 101 due to the pressure generated during the clamping process.

[0027] In this embodiment, after the control arm 101 is fixed to the top of the tooling body 1 by the clamping member 102, the operator can turn the crank 112 to drive the screw 111. When the screw 111 rotates, it can push the second clamping plate 113 to slide to the right inside the tooling body 1 through the second slide groove 115. The second clamping plate 113 drives the soft pad 114 to move synchronously so that the soft pad 114 fits against the left side of the control arm 101 and fixes the control arm 101.

[0028] Example 2, as Figures 1-7 As shown, the heat dissipation assembly includes: a slide rod 2 is fixedly installed on the top front side of the tooling body 1, and a support rod 201 is slidably connected to the outer surface of the slide rod 2. In this design, the sliding connection between the slide rod 2 and the support rod 201 allows the position of the support rod 201 to be flexibly adjusted. Through sliding adjustment, the support rod 201 can move up and down or back and forth within a certain range. The bottom of the support rod 201 is movably connected to the top of the tooling body 1. The support rod 201 has a movably embedded pin 202 inside, and the slide rod 2 has multiple pin slots 203 inside. In this design, the cooperation between the pin 202 and the pin slots 203 provides a high-precision positioning and locking function to ensure that the position of the support rod 201 is stable and fixed. The pin 202 matches the multiple pin slots 203. The support rod 201 is movably connected to the fan 204. Movable rods 205 are fixedly installed on both outer surfaces of the fan 204. Both movable rods 205 are movably embedded inside the support rod 201. One of the movable rods 205 has a limiting gear 206 fixedly installed on its left side, and a limiting post 207 is movably embedded inside the support rod 201. In this design, the cooperation between the limiting post 207 and the limiting gear 206 provides a precise positioning mechanism to fix the position of the fan 204. The top of the limiting post 207 is provided with teeth, and the limiting post 207 meshes with the limiting gear 206.

[0029] In this embodiment, after the support rod 201 slides to the appropriate position, the operator can push the pin 202 backward so that it can slide backward inside the support rod 201 and pass through the pin groove 203 to fix the position of the support rod 201.

[0030] Working principle: In use, the operator first places the control arm 101 on top of the tooling body 1, ensuring that the connecting hole on the right side of the control arm 101 fits onto the outer surface of the clamping member 102. Then, the operator activates the electric push rod 103 via its power supply system, causing it to extend and push the pusher 104 upwards. When the pusher 104 moves, it pushes the slider 107 to slide on the inner surface of the first slide groove 108. As the slider 107 moves, it presses the pusher block 106 outwards via the pusher 104. When the pusher block 106 is pressed, it pushes the first clamping plate 109 outwards via the connecting post 105, thus clamping the first clamping plate 109. The plate 109 can slide inside the clamping member 102, and at the same time, the return spring 110 can be extended by pulling the first clamping plate 109, so that the soft pad 114 can be driven by the first clamping plate 109 to fit against the inner wall of the connection hole on the control arm 101, fixing the control arm 101 to the top of the tooling body 1. Moreover, through the structure of the pusher 104 and the first clamping plate 109, when the operator welds the reinforcing ribs or reinforcing plates on the control arm 101, the operator can accurately fix the control arm 101 to the top of the tooling body 1 without having to manually install the control arm 101 continuously. This greatly reduces the cumbersomeness of the operator's operation and improves the convenience of fixing and disassembling. In use, after the reinforcing ribs on the control arm 101 are welded, the operator can start the fan 204 via its power supply system. During operation, the fan blows air onto the weld seams of the control arm 101 to dissipate heat. Simultaneously, the operator can push the support rod 201 to slide it across the top of the fixture body 1 via the slide rod 2, adjusting the position of the fan 204. Furthermore, the operator can press down on the fan 204, causing it to rotate downwards within the support rod 201 via the movable rod 205, thus adjusting the blowing angle of the fan 204. After the angle of the fan 204 is adjusted, the operator can insert the pin 202 into the support rod 201 and lock it into the limit gear 206 to fix the angle of the fan 204. The structure of the fan 204 and the movable rod 205 can not only quickly reduce the temperature of the welding area, allowing the welded control arm 101 to dissipate heat quickly, thereby improving the welding quality and reducing welding deformation, but also allows the operator to easily adjust the position and angle of the fan 204 so that it can blow more accurately onto the welding area on the control arm 101.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
