Detailed Implementation
[0025] 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.
[0026] Example
[0027] Please see Figure 1-4This embodiment provides a wheel hub processing and fixing fixture, including a support mechanism 100, two clamping mechanisms 200 that cooperate with each other to clamp and fix a motorcycle wheel hub, an adjusting mechanism 300 for adjusting the distance between the two clamping mechanisms 200, and a flipping mechanism 400 for flipping. The two clamping mechanisms 200 are both located above the support mechanism 100, the adjusting mechanism 300 is located on the support mechanism 100, and the flipping mechanism 400 is located between the adjusting mechanism 300 and the two clamping mechanisms 200. The clamping mechanism 200 includes a clamping plate 210. Both sides of the surface of the clamping plate 210 are integrally formed with a set of inclined plates 211. Each set of inclined plates 211 has two plates arranged vertically, and the inclination directions of the two inclined plates 211 are opposite. A clamping surface is formed between the clamping plate 210 and the two inclined plates 211. A rubber pad 220 is fixedly connected to the inner wall of the clamping surface.
[0028] Working principle: In use, the first stepper motor 310 is started, causing its output shaft to drive the linkage plate 330 to rotate. The linkage plate 330 drives the groove 331, the ball bearing 332, and one end of the connecting rod 340 to move synchronously, causing the ball bearing 332 to roll within the slide groove 112, thereby reducing the friction between the linkage plate 330 and the housing 110. At the same time, the other end of the connecting rod 340 pulls or pushes the protrusion 350 to slide within the cavity of the through groove 111, causing the two protrusions 350 to move towards or away from each other. The protrusions 350 drive the support plate 320, the tilting mechanism 400, and the clamping mechanism 200 to move synchronously, thus adjusting the position of the motorcycle wheel. Adjust the distance between the two clamping mechanisms 200 according to the hub diameter. Then, according to the processing requirements, place the clamping mechanisms 200 on the outer or inner wall of the motorcycle wheel hub. Start the first stepper motor 310 again, so that the output shaft of the first stepper motor 310 drives the two clamping mechanisms 200 to move and clamp and fix the motorcycle wheel hub, so that the rubber pad 220 is tightly attached to the motorcycle wheel hub, thereby completing the clamping and fixing operation of the motorcycle wheel hub. Start the second stepper motor 410, so that the output shaft of the second stepper motor 410 drives the clamping mechanism 200, the support column 420 and the motorcycle wheel hub to rotate, so that the motorcycle wheel hub can be processed at different angles and rotated.
[0029] Furthermore, the support mechanism 100 includes a housing 110, with a bracket 120 fixedly connected to the bottom of the housing 110. Clamping plates 210 are located directly above the housing 110, and the two clamping plates 210 are symmetrically arranged about the central axis of the housing 110. This design provides a mounting base for the adjusting mechanism 300.
[0030] Furthermore, the adjusting mechanism 300 includes a first stepper motor 310 installed at the bottom of the inner cavity of the bracket 120. Two symmetrically arranged support plates 320 are slidably connected to the top of the housing 110. Two clamping plates 210 are located between the two support plates 320, and the support plates 320 and clamping plates 210 are arranged in a one-to-one correspondence. The output shaft of the first stepper motor 310 passes through the inner cavity of the housing 110 and shares a linkage with the two support plates 320. With this design, starting the first stepper motor 310 will drive the two support plates 320 to move towards or away from each other via the linkage.
[0031] Furthermore, the linkage includes a linkage plate 330 fixedly connected to the output shaft of the first stepper motor 310. Connecting rods 340 are rotatably connected to both sides of the top of the linkage plate 330 via rotating shafts. The connecting rods 340 and support plates 320 are arranged in a one-to-one correspondence, and protrusions 350 are provided between the connecting rods 340 and their corresponding support plates 320. This design enables the output shaft of the first stepper motor 310 to drive the two support plates 320 to move synchronously.
[0032] Furthermore, the top of the protrusion 350 is fixedly connected to the corresponding support plate 320, and the bottom of the protrusion 350 is rotatably connected to the corresponding connecting rod 340 via a rotating shaft. A through groove 111 is provided on the top of the housing 110 for the protrusion 350 to pass through, and the inner wall of the through groove 111 slides against the surface of the protrusion 350. This design ensures that the protrusion 350 can move normally with the connecting rod 340, and also guides the support plate 320 in conjunction with the protrusion 350, allowing the support plate 320 to move stably horizontally on the top of the housing 110.
[0033] Furthermore, grooves 331 are provided on both sides of the bottom of the linkage plate 330, and ball bearings 332 are movably embedded in the inner cavity of the grooves 331. A sliding groove 112 for the ball bearings 332 to roll is provided at the bottom of the inner cavity of the housing 110. With the above design, when the linkage plate 330 rotates, it can drive the grooves 331 and the ball bearings 332 to rotate synchronously, so that the ball bearings 332 roll in the inner cavity of the sliding groove 112. This helps to reduce the friction between the linkage plate 330 and the bottom of the inner cavity of the housing 110, and improves the rotational flexibility of the linkage plate 330.
[0034] Furthermore, the flipping mechanism 400 includes a second stepper motor 410 located on one side of one of the support plates 320. The output shaft of the second stepper motor 410 is fixedly connected to its adjacent clamping plate 210. A support column 420 is provided between the other support plate 320 and its adjacent clamping plate 210. One end of the support column 420 is fixedly connected to the clamping plate 210, and the other end of the support column 420 is rotatably connected to the support plate 320 via a bearing. With the above design, after the clamping mechanism 200 clamps and fixes the motorcycle wheel hub, starting the second stepper motor 410 will drive the clamping mechanism 200 and the motorcycle wheel hub to flip through the output shaft of the second stepper motor 410, so as to perform processing on the motorcycle wheel hub at different angles and flipping processing.
[0035] Furthermore, a support 430 is mounted on the bottom of the second stepper motor 410, and one side of the support 430 is fixedly connected to the corresponding support plate 320. The output shaft of the second stepper motor 410 and the central axis of the support 420 are on the same straight line. The above design can support the second stepper motor 410 to ensure the stability of the second stepper motor 410 during operation.
