Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive steel wheel processing fixture. Background Technology
[0002] Automotive parts processing is a crucial foundation of the automotive manufacturing industry. Among them, automotive steel wheels, as key components of the vehicle's driving system, directly affect the vehicle's safety, stability, and comfort through their processing quality. During the steel wheel processing, fixtures are the core equipment for ensuring processing accuracy and production efficiency. They need to accurately fix the steel wheel in the processing position and resist the influence of external forces such as cutting forces and vibrations during the processing to prevent the steel wheel from shifting or deforming.
[0003] In existing technologies, traditional clamping plates are mostly fixed or bolted. When the clamping plates wear out or need to be replaced with clamping plates of different specifications to fit different steel rings, the disassembly and installation process is cumbersome and time-consuming, which seriously affects production efficiency. On the other hand, in the steel ring clamping process, some clamps rely on manual operation to complete multiple steps of positioning and clamping. This is not only labor-intensive, but also difficult to avoid errors in manual operation, which can easily lead to inaccurate steel ring clamping, thereby affecting processing accuracy. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of difficulty in replacing clamping plates, complexity of manual operation and easy clamping errors in the existing technology, and to propose an automotive steel wheel processing fixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automotive steel wheel processing fixture, comprising a base and a vertical plate, wherein a placement plate is provided on the upper surface of the base, a fixing plate is fixedly installed on the upper surface of the base, a connecting block is slidably connected inside the fixing plate, a hydraulic cylinder is fixedly installed on the side of the fixing plate, a sliding rod is fixedly installed inside the fixing plate, an installation frame is provided on the inner side of the vertical plate, an installation plate is fixedly installed on the side of the installation frame, a clamping plate is fixedly installed on the side of the installation plate, a connecting block is slidably connected inside the vertical plate, a hydraulic cylinder is fixedly installed on the surface of the vertical plate, a sliding rod is fixedly installed inside the vertical plate, a disassembly mechanism is provided on the side of the installation plate, sliding blocks are installed on both sides of the installation plate, a bidirectional lead screw is rotatably connected inside the installation frame, a motor is fixedly installed on the side of the installation frame, and a guide rod is fixedly installed inside the installation frame;

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] 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.
[0024] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a jig for processing automotive steel rims, including a base 1 and a vertical plate 2. A placement plate 3 is provided on the upper surface of the base 1, and a fixing plate 4 is fixedly installed on the upper surface of the base 1. A connecting block 5 is slidably connected inside the fixing plate 4. A hydraulic cylinder 6 is fixedly installed on the side of the fixing plate 4, and a sliding rod 7 is fixedly installed inside the fixing plate 4. A mounting frame 8 is provided on the inner side of the vertical plate 2, and a mounting plate 9 is fixedly installed on the side of the mounting frame 8. A clamping plate 10 is fixedly installed on the side of the mounting plate 9. A clamping plate 10 is slidably connected inside the vertical plate 2. Connecting block 2 11, hydraulic cylinder 2 12 is fixedly installed on the surface of the upright plate 2, sliding rod 2 13 is fixedly installed inside the upright plate 2, disassembly mechanism 14 is provided on the side of the mounting plate 9, sliding blocks 15 are installed on both sides of the mounting plate 9, a two-way lead screw 16 is rotatably connected inside the mounting frame 8, motor 17 is fixedly installed on the side of the mounting frame 8, guide rod 18 is fixedly installed inside the mounting frame 8, disassembly mechanism 14 includes side frame 141, insert block 142 is fixedly installed on the side of the clamping plate 10, slot 143 is opened on the surface of the mounting plate 9, side frame 141 An internal sliding connection is provided with a movable plate 144. A limit rod 145 is fixedly installed on the inner side of the movable plate 144. A tension spring 146 is sleeved on the surface of the limit rod 145. A limit hole 147 is opened on the side of the insert block 142. The side of the connecting block 15 is fixedly connected to the side of the placement plate 3. The output end of the hydraulic cylinder 16 is fixedly connected to the side of the connecting block 15. The connecting block 15 is slidably connected to the slide rod 17. The side of the connecting block 21 is fixedly connected to the side of the mounting frame 8. The output end of the hydraulic cylinder 212 is fixedly connected to the surface of the connecting block 21. The connecting block 11 and the slide rod 13 are slidably connected. The placement plate 3 is located below the mounting frame 8. The output end of the motor 17 is fixedly connected to one end of the bidirectional lead screw 16. The bidirectional lead screw 16 is threadedly connected to the sliding block 15. The sliding block 15 is slidably connected to the guide rod 18. The insert block 142 is slidably connected to the slot 143. The limiting rod 145 is slidably connected to the limiting hole 147. One end of the tension spring 146 is fixedly connected to the side of the moving plate 144. The other end of the tension spring 146 is fixedly connected to the inner side of the side frame 141.
[0025] In this embodiment, when the clamping plate 10 needs to be installed, the insert 142 on the side of the clamping plate 10 is aligned with the slot 143 on the surface of the mounting plate 9 and inserted. During the insertion process, the insert 142 presses the limiting rod 145, causing the moving plate 144 to slide within the side frame 141 and compress the tension spring 146. When the insert 142 is fully inserted into the slot 143 and the limiting hole 147 is aligned with the limiting rod 145, the tension spring 146 resets and pushes the moving plate 144, causing the limiting rod 145 to insert into the limiting hole 147, thus completing the quick installation of the clamping plate 10. When disassembling, the moving plate 144 is pulled outward to compress the tension spring 146, causing the limiting rod 145 to disengage from the limiting hole 147, and the insert 142 can then be removed from the slot. The clamping plate 10 is easily disassembled by pulling out the 143, which facilitates operation when the clamping plate 10 is worn or needs to be replaced with a different type, thus improving production efficiency. At the same time, hydraulic cylinder 6 pushes connecting block 5 to slide on slide rod 7, causing the placement plate 3 to move horizontally to below the mounting frame 8 and clamping plate 10. Hydraulic cylinder 12 drives connecting block 11 to slide on slide rod 13, causing the mounting frame 8 to move up and down to adjust its height. Motor 17 drives the bidirectional lead screw 16 to rotate, causing sliding block 15 to slide along guide rod 18 through threaded transmission, causing mounting plate 9 and clamping plate 10 to move in opposite directions, thus achieving precise clamping and releasing of the steel ring. The linkage control of each mechanism reduces manual intervention and lowers the risk of operational errors.
[0026] Example 2: As Figures 1-4 As shown, a mounting bracket 19 is fixedly installed on the surface of the base 1, a fan 20 is fixedly installed on the surface of the mounting bracket 19, a connecting pipe 21 is fixedly connected to the output end of the fan 20, a ventilation plate 22 is fixedly installed on the inner side of the mounting bracket 19, a jet nozzle 23 is fixedly connected to the side of the ventilation plate 22, and one end of the connecting pipe 21 is connected to the interior of the ventilation plate 22.
[0027] In this embodiment, after the steel ring is processed, the clamping assembly is released and the workpiece falls back onto the surface of the placement plate 3. The placement plate 3 is then moved horizontally to below the mounting frame 19 by the hydraulic cylinder 6. At this time, the blower 20 is started, and air is delivered to the ventilation plate 22 through the connecting pipe 21. The surface of the steel ring is then thoroughly cleaned by multiple evenly distributed jet nozzles 23, thereby achieving automated cleaning. This cleaning component avoids the tediousness of manual wiping, improves the surface quality of the workpiece, provides a clean foundation for subsequent coating, inspection and other processes, and prevents debris residue from affecting the performance of the steel ring, thus enhancing the integrity and practicality of the fixture function.
[0028] The working principle of this embodiment is as follows: In use, firstly, the car wheel is placed on the surface of the placement plate 3 on the base 1. Then, hydraulic cylinder 6 is activated, causing its output end to push connecting block 5. Connecting block 5 slides under the guidance of slide rod 7, thereby moving the placement plate 3 horizontally until it moves directly below the mounting frame 8 and clamping plate 10. Next, hydraulic cylinder 12 is activated, causing its output end to push connecting block 11. Connecting block 11 slides along slide rod 13, causing the mounting frame 8 to move downwards. Once the mounting frame 8 has moved to the appropriate position, motor 17 is activated, causing its output end to drive the double... Rotating the lead screw 16 causes the mounting plate 9 and clamping plate 10 to move synchronously towards the steel ring due to the threaded connection between the lead screw 16 and the sliding block 15, thus clamping and fixing the steel ring. After clamping, the hydraulic cylinder 12 is activated again to move the mounting frame 8 upward, sending the clamped steel ring to the processing station for processing. After the steel ring is processed, the hydraulic cylinder 12 is activated again to move the mounting frame 8 downward, sending the processed steel ring back to a suitable position above the placement plate 3. Then, the motor 17 is controlled to reverse, causing the lead screw 16 to rotate in the opposite direction, causing the sliding blocks 15 on both sides to move the clamping plate 10 in opposite directions, releasing the steel ring. The clamping mechanism of the steel ring is engaged, and the steel ring falls onto the placement plate 3. Then, hydraulic cylinder 6 is activated to move the placement plate 3 to the working area of the jet nozzle 23 below the mounting bracket 19. At this time, the blower 20 is activated, and the airflow generated by the blower 20 is delivered to the ventilation plate 22 through the connecting pipe 21, and then sprayed out through the jet nozzle 23 to blow and clean the surface of the steel ring, removing metal debris, dust and other impurities. If the clamping plate 10 needs to be replaced, the limit rod 145 is pulled. At this time, the moving plate 144 moves synchronously and compresses the tension spring 146. When the limit rod 145 disengages from the limit hole 147 of the insert block 142... When the old clamping plate 10 is disassembled, the insert 142 can be pulled out from the slot 143 of the mounting plate 9. When installing the new clamping plate 10, the insert 142 on the side of the new clamping plate 10 is aligned with the slot 143 of the mounting plate 9 and inserted. During the insertion of the insert 142, the limiting rod 145 is squeezed to make the moving plate 144 slide and compress the tension spring 146. When the insert 142 is fully inserted into the slot 143 and the limiting hole 147 is aligned with the limiting rod 145, the tension spring 146 returns to its original position and pushes the moving plate 144 so that the limiting rod 145 is inserted into the limiting hole 147, thus completing the quick installation of the new clamping plate 10.
[0029] 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.
