[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Example 1, please refer to Figures 1 to 6, the present utility model provides a technical solution: an automotive part welding fixture, which includes two fixture bodies 1. On the outer side of the inner walls of the two fixture bodies 1, first chutes 101 are respectively opened. A plurality of first sliders 102 are slidably connected to the inner surfaces of the two first chutes 101. The plurality of first sliders 102 are divided into two groups. On the opposite sides of the two groups of first sliders 102, rotating discs 103 are fixedly installed. The two rotating discs 103 are movably embedded in the fixture bodies 1. On the outer surfaces of the two rotating discs 103, first bevel gears 104 are fixedly sleeved. In the two fixture bodies 1, rotating rods 105 are movably embedded. On the outer surfaces of the bottoms of the two rotating rods 105, second bevel gears 107 are fixedly sleeved. The two second bevel gears 107 are respectively meshed with the adjacent first bevel gears 104. At the tops of the two rotating rods 105, first cranks 106 are fixedly installed. In the two rotating discs 103, a plurality of arc-shaped slide rails 108 are respectively opened. On the inner surfaces of the plurality of arc-shaped slide rails 108, movable rods 109 are movably connected. On the opposite sides of the plurality of movable rods 109, second sliders 112 are fixedly installed. In the two fixture bodies 1, partitions 110 are fixedly embedded. In the two partitions 110, a plurality of second chutes 111 are respectively opened. The outer surfaces of the plurality of second sliders 112 are slidably connected to the inner surfaces of the second chutes 111. On the inner sides of the plurality of second sliders 112, clamping plates 113 are fixedly installed. On the outer surfaces of the two fixture bodies 1, support plates 114 are movably sleeved. On the outer surface of one of the fixture bodies 1, a worm gear 115 is fixedly sleeved. On the left side of one of the support plates 114, a second crank 117 is movably embedded. On the front side of the second crank 117, a worm 116 is fixedly installed. The worm 116 is meshed with the worm gear 115. The bottoms of the two support plates 114 are movably connected to a base 2.

[0033] In this embodiment, first, the cylindrical part is embedded into the interior of the fixture body 1, and the first crank 106 is rotated to drive the second bevel gear 107 through the rotating rod 105. Then, the second bevel gear 107 drives the first bevel gear 104, thereby driving the rotating disk 103 to rotate. At the same time, the first slider 102 slides on the inner surface of the first chute 101. When the rotating disk 103 rotates, it drives the movable rod 109 to move through the arc-shaped slide rail 108, and at the same time, pulls the movable rod 109 to slide inward through its arc angle. When the movable rod 109 moves, it can drive the second slider 112 to slide inward through the second chute 111 on the partition plate 110, and then the second slider 112 drives the clamping plate 113 to move synchronously, so that the clamping plate 113 can fit the outer surface of the part to fix the part. When it is necessary to replace the welding surface of the part, the second crank 117 on the support plate 114 can be rotated to drive the worm gear 115 through the worm 116. When the worm gear 115 rotates, through structures such as the fixture body 1, the part is driven to rotate synchronously, thereby adjusting the welding surface of the part. Through structures such as the rotating disk 103 and the clamping plate 113, the fixture body 1 can not only accurately clamp and fix the cylindrical part, but also has a certain adjustment ability, making it applicable to cylindrical parts of different sizes, improving the flexibility and efficiency of processing. And through structures such as the worm gear 115 and the worm 116, personnel can quickly adjust the welding position without disassembling the part, reducing the time for part loading and unloading, accelerating the production rhythm, and improving the overall production efficiency.

[0034] Embodiment 2, as Figures 1 to 6 shown, a forward rotation lead screw 203 is movably embedded on the right side inside the base 2. A reverse rotation lead screw 204 is fixedly installed on the left side of the forward rotation lead screw 203. The left outer surface of the reverse rotation lead screw 204 is movably embedded on the left inner wall of the base 2. A motor 205 is fixedly installed on the right side of the forward rotation lead screw 203. Third sliders 201 are threadedly connected to the outer surfaces of both the forward rotation lead screw 203 and the reverse rotation lead screw 204. A third chute 202 is formed at the center of the top of the base 2. The outer surfaces of the two third sliders 201 are slidably connected to the inner surface of the third chute 202. The tops of the two third sliders 201 are fixedly installed at the bottom of the support plate 114.

[0035] In this embodiment, the operator can first fix two parts on the fixture body 1, and then start the motor 205 through the power supply system of the motor 205. When the motor 205 is running, it drives the forward rotation screw rod 203 through the output shaft, and then the forward rotation screw rod 203 drives the reverse rotation screw rod 204. When the forward rotation screw rod 203 and the reverse rotation screw rod 204 rotate, they can drive the third slider 201 to perform translational sliding in the opposite direction through the third chute 202 opened on the base 2. When the third slider 201 slides, it can drive the two parts to move synchronously through structures such as the support plate 114 and the fixture body 1, thereby enabling the docking of the two parts. Moreover, through structures such as the forward rotation screw rod 203 and the third slider 201, precise translation during the part docking process is achieved, improving the accuracy and repeatability of docking, which helps to ensure the quality of the final welding or assembly.

[0036] Working principle: When in use, first embed the cylindrical part into the interior of the fixture body 1, and rotate the first crank 106 to drive the second bevel gear 107 through the rotating rod 105, and then drive the first bevel gear 104 by the second bevel gear 107, thereby driving the rotating disk 103 to rotate. At the same time, the first slider 102 slides on the inner surface of the first chute 101. When the rotating disk 103 rotates, it drives the movable rod 109 to move through the arc-shaped slide rail 108, and at the same time pulls the movable rod 109 to slide inward through its arc angle. When the movable rod 109 moves, it can drive the second slider 112 to slide inward through the second chute 111 on the partition plate 110, and then drive the clamping plate 113 by the second slider 112 to move synchronously, so that the clamping plate 113 can fit the outer surface of the part to fix the part. When it is necessary to replace the welding surface of the part, the second crank 117 on the support plate 114 can be rotated to drive the worm gear 115 through the worm 116. When the worm gear 115 rotates, through the fixture body 1 and other structures, drive the part to rotate synchronously, thereby adjusting the welding surface of the part. Through the rotating disk 103 and the clamping plate 113 and other structures, the fixture body 1 can not only accurately clamp and fix the cylindrical part, but also has a certain adjustment ability, making it suitable for cylindrical parts of different sizes, improving the flexibility and efficiency of processing. And through the worm gear 115 and the worm 116 and other structures, personnel can quickly adjust the welding position without disassembling the part, reducing the time for part loading and unloading, accelerating the production rhythm, and improving the overall production efficiency. When in use, personnel can first fix two parts on the fixture body 1, and then start the motor 205 through the power supply system of the motor 205. When it operates, it drives the forward rotation lead screw 203 through the output shaft, and then drives the reverse rotation lead screw 204 by the forward rotation lead screw 203. When the forward rotation lead screw 203 and the reverse rotation lead screw 204 rotate, they can drive the third slider 201 to perform translational sliding in the opposite direction through the third chute 202 opened on the base 2. When the third slider 201 slides, it can drive the two parts to move synchronously through the support plate 114 and the fixture body 1 and other structures, thereby being able to dock the two parts. And through the forward rotation lead screw 203 and the third slider 201 and other structures, accurate translation during the part docking process is achieved, improving the accuracy and repeatability of docking, and helping to ensure the quality of the final welding or assembly.
