This invention has a reasonable structure. Through the connecting rod located on one side of the inner wall of the welding box, and the snap-fit ​​plate and limiting spring inside the protective door, the sliding plate can move the welding assembly, thereby causing the protective door to rotate. This allows for convenient opening and closing of the protective door, saving time compared to manual opening and closing, and improving the efficiency of the welding device for automotive shock absorber parts.

[0004] However, this patented technology also has the following drawbacks: the internal space of the clamping plate in this patented technology is fixed in height, which limits its applicable range. For example, if the welded parts are thin, this clamping plate cannot clamp them securely. Utility Model Content

[0005] In view of the above technical problems, this utility model provides a welding positioning device for automotive parts that facilitates the adjustment of the position of the welded parts.

[0006] This utility model provides a welding positioning device for automotive parts, including a base plate. The base plate is characterized by having multiple support platforms on one side of its top, each support platform being fixedly connected to a fixing frame. One end of the fixing frame is detachably connected to a connecting rod via bolts, and one end of the connecting rod is provided with a positioning and pressing mechanism. A receiving seat is correspondingly provided below each positioning and pressing mechanism.

[0007] The positioning and clamping unit includes a rotating rod, a pressure block, and a connecting seat. One side of the connecting seat is fixed to the bottom of the connecting rod by bolts, and the other side of the connecting seat is threaded to the rotating rod. The bottom of the rotating rod is connected to the pressure block.

[0008] The swivel rod is connected to the connecting rod through a thread.

[0009] The leftmost support at the top of the base plate is an inverted L-shape, and a positioning block is fixedly connected to the bottom of the support. A positioning and clamping mechanism is set on one side of the bottom of the connecting rod at the top of the base plate. A diagonal rod is connected to the side of the positioning and clamping mechanism. A T-shaped pressure column is bolted to the bottom of one side of the diagonal rod. A positioning platform is set below the T-shaped pressure column. A positioning pin is connected to the positioning platform. A sensor is set next to the positioning pin.

[0010] The mounting bracket is Y-shaped.

[0011] The bottom of the base plate is provided with four brake wheels, and the four corners of the base plate are threaded to the adjustment seats. The bottom of the adjustment seats is provided with frustum-shaped supports.

[0012] The beneficial effects of this utility model are as follows: This utility model is a welding positioning device for automotive parts. By setting multiple support platforms and a corresponding positioning and clamping mechanism on each support platform, it achieves multi-point fixation of automotive parts, increases their stability, and facilitates subsequent welding work. By setting positioning blocks, the automotive parts are fixed against the positioning blocks, i.e., one point of the automotive parts is fixed, which facilitates the fixation of other positions of the automotive parts and makes it easier for workers to quickly find the placement point. By setting sensors, preferably pressure sensors, the pressure of the clamping block on the automotive parts is controlled when the rotating rod is rotated. When the sensor senses the appropriate pressure, it can prompt the worker to stop the operation of rotating the rod through its external sound control, preventing the clamping block from putting too much pressure on the automotive parts and causing damage. The T-shaped clamping column set on the far right can be adapted to some irregularly shaped automotive parts to press down the protruding parts. If there are no irregular shapes, this part can be omitted. Attached Figure Description

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0020] like Figure 1 As shown, this utility model provides a welding positioning device for automotive parts, including a base plate 1. The base plate 1 is characterized by having multiple support platforms 15 on one side of its top. Each support platform 15 is fixedly connected to a fixing frame 2. One end of the fixing frame 2 is detachably connected to a connecting rod 3 via bolts 9. One end of the connecting rod 3 is provided with a positioning and pressing mechanism. A receiving seat 8 is provided below each positioning and pressing mechanism.

[0021] The positioning and clamping unit includes a rotating rod 10, a pressure block 11, and a connecting seat 12. One side of the connecting seat 12 is fixed to the bottom of the connecting rod 3 by bolts 9, and the other side of the connecting seat 12 is threaded to the rotating rod 10. The bottom of the rotating rod 10 is connected to the pressure block 11.

[0022] The swivel rod 10 is connected to the connecting rod 3 via a through thread.

[0023] The support seat 8 located on the far left of the top of the base plate 1 is an inverted L-shape, and the bottom of the support seat 8 is fixedly connected to the positioning block 6; a positioning and clamping mechanism is set on one side of the bottom of the connecting rod 3 located on the far right of the top of the base plate 1, and a diagonal rod 16 is connected to the side of the positioning and clamping mechanism. A T-shaped pressure column 17 is connected to one side of the bottom of the diagonal rod 16 by a bolt 9. A positioning platform 7 is set below the T-shaped pressure column 17, and a positioning pin 4 is connected on the positioning platform 7. A sensor 5 is set on the side of the positioning pin 4.

[0024] The mounting bracket 2 is Y-shaped.

[0026] Example 2

[0027] In use, this invention involves placing the automotive part on multiple receiving seats 8, with one corner of the part secured by a positioning block 6. When this corner abuts the positioning block 6, the entire part is positioned within the positioning pin 4 of the positioning platform 7. Then, rotating the various rotating rods 10 causes the pressure block 11 to move downwards, securing the part. Simultaneously, rotating the positioning pin 4 fixes the part in place. During this fixing process, the part exerts pressure on the sensor 5 on the positioning platform 7. When the pressure reaches a suitable range, the rotation of the rotating rods 10 is stopped. The device then firmly clamps and fixes the automotive part for subsequent processing. Preferably, the sensor is a pressure sensor.

[0028] After processing is completed, the adjusting seat 14 is rotated to move it upward. At this time, the brake wheel 13 touches the ground and moves, moving the entire device to the appropriate position.
