A welding fixture for inner liner processing of rear wheels

Abstract

This utility model discloses a welding fixture for the inner liner of a rear wheel, including a pneumatic clamp for the wheel rim. A movable seat is provided below the pneumatic clamp for the wheel rim. A base is slidably mounted on the movable seat, and a slide is installed on one side of the base. A support structure is connected to the slide, and an installation shaft is installed on the inner wall of the slide. After the rear wheel rim is welded, a multi-stage cylinder can be activated to control the U-shaped material plate to rise. As the U-shaped material plate rises, it can drive the first and second linkage shafts to rise. When the second linkage shaft moves into the arc-shaped sliding hole, it will be affected by the arc surface of the arc-shaped sliding hole and cause the U-shaped material plate to flip, thereby causing the welded wheel rim to tilt. This allows the wheel rim to slide down along the inclined surface and onto the slide, achieving rapid unloading of the wheel rim. This eliminates the tedious steps of manual disassembly, shortens the processing cycle of a single rear wheel, and avoids burns caused by touching the welding position during manual unloading.

Its main function is to achieve precise positioning and clamping of the various components of the inner liner, and to provide stable support for the welding process, ensuring welding quality and production efficiency.

[0003] In the existing technology, when welding the rear wheel rim to the spokes, workers need to manually pick up and put down the materials. Manual material handling is tedious and time-consuming. Moreover, after the wheel rim is welded, the temperature of the welding position is high. If the welding position is accidentally touched while manually handling the material, it can easily cause burns. Therefore, there is a need for a welding fixture for the inner liner of the rear wheel to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a welding fixture for the inner liner of the rear wheel to solve the problem mentioned in the background art that the rear wheel rim welding requires workers to manually pick up and put down materials, and the temperature of the welding position is high after the rim welding is completed, which can easily cause burns if the welding position is accidentally touched.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for inner liner processing of rear wheels, including a wheel rim pneumatic clamp, a movable seat is provided below the wheel rim pneumatic clamp; a base is slidably sleeved on the movable seat, a slide is installed on one side of the base, a support structure is connected to the slide, an installation shaft is installed on the inner wall of the slide, a material unloading structure is connected to the installation shaft, a bevel gear ring is rotatably installed inside the base, and a height adjustment structure is connected to the bevel gear ring.

[0006] Preferably, the support structure includes two vertical sliding holes, both of which are opened inside the slide frame. A first linkage shaft and a second linkage shaft are movably installed in each of the two vertical sliding holes, and the same U-shaped material placement plate is installed on the two first linkage shafts and the two second linkage shafts.

[0007] Preferably, the unloading structure includes a multi-stage cylinder, one end of which is rotatably mounted on a mounting shaft, and the telescopic end of which is rotatably mounted on a connecting shaft, which is mounted on a U-shaped material placement plate.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a welding fixture for inner liner processing of rear wheels, including a wheel rim pneumatic clamp 100, with a movable seat 101 below the wheel rim pneumatic clamp 100; a base 200 is slidably sleeved on the movable seat 101, a slide 201 is installed on one side of the base 200, a support structure is connected to the slide 201, the support structure is used to place the rear wheel rim for support, an installation shaft 209 is installed on the inner wall of the slide 201, an unloading structure is connected to the installation shaft 209, the unloading structure is used to remove the material from the rear wheel rim after welding is completed, a bevel gear ring 300 is rotatably installed inside the base 200, a height adjustment structure is connected to the bevel gear ring 300, the height adjustment structure is used to adjust the height of the wheel rim pneumatic clamp 100.

[0024] Furthermore, the support structure includes two vertical sliding holes 202, both of which are opened inside the carriage 201. A first linkage shaft 203 and a second linkage shaft 204 are movably installed in each of the two vertical sliding holes 202. The same U-shaped material plate 205 is installed on the two first linkage shafts 203 and the two second linkage shafts 204. In use, the rear wheel rim with spokes can be placed on the U-shaped material plate 205 and fitted onto the wheel rim pneumatic clamp 100. The U-shaped material plate 205 is used for support. By opening the wheel rim pneumatic clamp 100, the wheel rim can be supported from the inside and fixed.

[0025] Furthermore, the unloading structure includes a multi-stage cylinder 206. One end of the multi-stage cylinder 206 is rotatably mounted on the mounting shaft 209, and the telescopic end of the multi-stage cylinder 206 is rotatably mounted with a connecting shaft 207. The connecting shaft 207 is mounted on the U-shaped material placement plate 205. After welding is completed, the wheel rim can be released and the multi-stage cylinder 206 can be opened, so that its telescopic end drives the U-shaped material placement plate 205 and the welded wheel rim to rise, so that the wheel rim is separated from the wheel rim pneumatic clamp 100.

[0026] Furthermore, the slide 201 has an arc-shaped sliding hole 208 inside, which is connected to the vertical sliding hole 202. The second linkage shaft 204 is adapted to the arc-shaped sliding hole 208. The continuously rising second linkage shaft 204 will move in the arc-shaped sliding hole 208 and drive the U-shaped material plate 205 to flip, causing the welded rear wheel rim to tilt, so that the rear wheel rim slides down from the slide 201 along the inclined surface of the U-shaped material plate 205.

[0027] Example 2: As Figure 3-6 To facilitate adjustment of the pneumatic wheel clamp 100 based on the height of the welding equipment and the rear wheel rim, a height adjustment structure is provided. This structure includes a geared motor 301 mounted on a slide 201. A bevel gear 302 is installed at the output end of the geared motor 301, meshing with a bevel gear ring 300. Several lead screws 303 are rotatably mounted inside the base 200. A linkage gear 304 is installed at one end of each lead screw 303. A linkage gear ring 305 is installed on one side of the bevel gear ring 300, engaging with the linkage gear 304. The screw 303 is threaded with a threaded slide 306, which is installed on the outer surface of the movable seat 101. By turning on the reduction motor 301, the bevel gear 302 can drive the bevel gear ring 300 to rotate. The rotating bevel gear ring 300 can drive the linkage gear ring 305 to rotate, so that the linkage gear ring 305 can drive the screw 303 to rotate through meshing with the linkage gear 304. When the screw 303 rotates, it can drive the threaded slide 306 to move in the vertical direction, thereby driving the movable seat 101 and the wheel rim pneumatic clamp 100 to move up and down, adjusting the height position of the wheel rim pneumatic clamp 100.

[0028] Furthermore, the base 200 has several vertical grooves 307 inside, and the threaded slide block 306 is slidably installed in the corresponding vertical groove 307. When the lead screw 303 rotates, it can drive the threaded slide block 306 to slide in the vertical groove 307 through the threaded engagement with the threaded slide block 306. The setting of the vertical groove 307 can restrict the threaded slide block 306 to move only in the vertical direction.

[0029] Furthermore, a limiting ring 308 is installed on one side of the bevel gear ring 300. The limiting ring 308 is rotatably installed inside the base 200. The rotating bevel gear ring 300 can drive the limiting rings 308 on both sides to rotate inside the base 200. The setting of the limiting rings 308 can limit the rotation position of the bevel gear ring 300.

[0030] The working principle is as follows: The rear wheel rim with spokes is placed on the U-shaped material placement plate 205 for support, and simultaneously fitted onto the wheel rim pneumatic clamp 100. By activating the wheel rim pneumatic clamp 100, the rim is internally supported and fixed for welding. After welding is completed, the wheel rim pneumatic clamp 100 can be controlled to release the rim, and at the same time, the multi-stage cylinder 206 is activated, causing its telescopic end to drive the connecting shaft 207 to move and rise. The rising connecting shaft 207 can drive the U-shaped material placement plate 205 to rise, which in turn drives the linkage shaft 201. 3. The linkage shaft 204 slides within the vertical sliding hole 202. The continuously rising U-shaped material plate 205 drives the welded wheel rim to rise until the continuously moving linkage shaft 204 moves into the arc-shaped sliding hole 208. At this point, continuously controlling the rise of the linkage shaft 204 will cause it to rotate along the arc surface of the arc-shaped sliding hole 208, thus rotating the U-shaped material plate 205. While the U-shaped material plate 205 rotates, the multi-stage cylinder 206 will rotate on the mounting shaft 209 and the connecting shaft 207 to adapt to the angle change of the U-shaped material plate 205, ultimately forming... Figure 2 In the current state, the flipped U-shaped material plate 205 will cause the welded rear wheel rim to tilt, so that the rear wheel rim slides down from the slide 201 along the inclined surface of the U-shaped material plate 205, which facilitates unloading. After unloading is completed, the U-shaped material plate 205 can be lowered and reset.

[0031] By activating the reduction motor 301, the bevel gear 302 can be driven to rotate. When the bevel gear 302 rotates, it can drive the bevel gear ring 300 to rotate through meshing with it. The continuously rotating bevel gear ring 300 can drive the linkage gear ring 305 to rotate, so that the linkage gear ring 305 can drive the lead screw 303 to rotate through meshing with the linkage gear 304. When the lead screw 303 rotates, it can drive the threaded slide 306 to slide vertically through the threaded engagement with the threaded slide 306. In turn, the threaded slide 306 can drive the movable seat 101 and the wheel rim pneumatic clamp 100 to move up and down, so as to adjust the height position of the wheel rim pneumatic clamp 100 according to the height of the welding equipment or the wheel rim. At the same time, the multi-stage cylinder 206 can be activated to drive the linkage shaft 1 203 and linkage shaft 204 to move within the range of the vertical sliding hole 202, so as to adjust the height of the U-shaped material plate 205 so that it can adapt to the height change of the wheel rim pneumatic clamp 100.
