Description

A dimensional measuring device for automobile wheel hub processing Technical Field

[0001] This utility model relates to the field of wheel hub measuring devices, and more particularly to a dimensional measuring device for automobile wheel hub processing. Background Technology

[0002] As a key automotive component, the machining precision of automotive wheels directly affects the vehicle's safety, handling, and aesthetics. During wheel manufacturing, dimensional measurement is a crucial step in ensuring product quality, requiring precise inspection of parameters such as diameter, thickness, and roundness. With the increasing automation and intelligence in the automotive manufacturing industry, higher demands are placed on the efficiency, accuracy, and ease of operation of wheel measuring devices; traditional measurement methods are no longer sufficient to meet the needs of modern production lines.

[0003] Currently, existing automotive wheel hub size measuring devices suffer from several drawbacks. Firstly, their positioning and clamping efficiency is low, and their accuracy is insufficient. Traditional devices often employ manual alignment and clamping, relying heavily on operator experience. This makes it difficult to quickly align the wheel hub center with the measurement reference, and uneven clamping force can easily damage the wheel hub surface or cause shaking during measurement, affecting data accuracy. Secondly, the maintenance of core measuring components is inconvenient. For example, laser rangefinders, as precision components, require periodic calibration or replacement after long-term use. However, existing devices are mostly fixed installations, requiring complete disassembly during removal. This is not only time-consuming and labor-intensive but may also cause optical path misalignment due to reinstallation, further affecting measurement accuracy. To address these technical problems, this application proposes a size measuring device for automotive wheel hub processing. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dimensional measuring device for automobile wheel hub processing. Positioning plate one and positioning plate two are set perpendicularly to form an L-shaped reference surface, which can quickly restrict the axial and radial movement of the wheel hub body. The caliper spacing can be manually pre-adjusted by the handle. After releasing, spring one automatically resets to complete the clamping. When it is necessary to disassemble the laser rangefinder, simply pull the limit bracket upward to compress spring two to release the clamping of the laser rangefinder.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[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] Referring to Figures 1-3, one embodiment of this utility model is provided: a size measuring device for automobile wheel hub processing, including a worktable 2. A positioning plate 1 8 and a positioning plate 2 9 are fixedly connected to the top of the worktable 2. The positioning plate 1 8 is vertically arranged at the rear end of the positioning plate 2 9. A support rod 10, a scale 11, a limiting plate 12 and a clamping plate 13 are arranged at the top of the positioning plate 2 9. A sliding rod 1 4 is fixedly connected to the inner wall of the worktable 2. A caliper 6 is slidably connected to the outer wall of the sliding rod 1 4. The caliper 6 is slidably connected to the top of the worktable 2. A distance plate 22 is fixedly connected to the front end of the caliper 6. The rear end of the distance plate 22 is slidably connected to the front end of the worktable 2. A fixing frame 14 is fixedly connected to the front end of the worktable 2. A limiting frame 18 is connected to the inner wall of the fixing frame 14 through a sliding rod 2 15. A laser rangefinder 21 is arranged at one end of the fixing frame 14 and the limiting frame 18.

[0024] Specifically, slide bar 4 passes through caliper 6 and is fixed to the inner wall of workbench 2. Spring 5 is sleeved on slide bar 4, with one end abutting against the inner wall of workbench 2 and the other end connected to the left end of caliper 6. This causes caliper 6 to initially deflect to the right due to the spring force. The operator holds handle 7 and pulls caliper 6 to the left, compressing spring 5 and causing caliper 6 to move to the left along slide bar 4, making room for the placement of hub body 3. Hub body 3 is then placed on top of workbench 2, so that it is simultaneously in close contact with vertically set positioning plate 8 and positioning plate 9. Positioning plate 8 restricts the axial movement of the wheel hub, and positioning plate 9 restricts the radial movement of the wheel hub, forming an L-shaped positioning reference to ensure that the center of the wheel hub is aligned with the reference of the measuring device. When the handle 7 is released, spring 5 returns to its original position and pushes caliper 6 to move to the right. The right end of caliper 6 and positioning plate 9 together clamp the wheel hub body 3, achieving rapid positioning and clamping, and avoiding wheel hub shaking during measurement from affecting accuracy. The laser rangefinder 21 is activated, and the laser is directed towards the distance plate 22. The diameter value of the wheel hub body 3 can be obtained through the laser rangefinder 21, where the right end of positioning plate 8 is perpendicular to the left end of positioning plate 9.

[0025] Referring to Figures 1-3, the support rod 10 is located at the top of the positioning plate 2 9. The outer wall of the support rod 10 has markings 11 and a locking plate 13. A limiting plate 12 is fixedly connected to the top of the support rod 10. A sliding rod 2 15 is located on the inner wall of the fixing frame 14. A limiting plate 2 16 is fixedly connected to the bottom of the sliding rod 2 15. The limiting plate 2 16 is located at the bottom of the limiting frame 18. A spring 2 17 is located on the outer wall of the sliding rod 2 15. One end of the spring 2 17 is located at the top of the limiting plate 2 16, and the other end is located on the inner wall of the fixing frame 14. The limiting frame 1... A guide rod 19 is fixedly connected to the bottom of the workbench 2. The guide rod 19 is slidably connected to the inner wall of the fixed frame 14. A spring 5 is provided on the outer wall of the slide rod 4. One end of the spring 5 is provided on the inner wall of the workbench 2, and the other end of the spring 5 is provided on the left end of the caliper 6. A hub body 3 is provided at the top of the workbench 2. The hub body 3 is provided on the inner circumference of the positioning plate 8 and the positioning plate 9. A gasket 20 is fixedly connected to the inner circumference of both the fixed frame 14 and the limiting frame 18. The gasket 20 is made of rubber. A support leg 1 is fixedly connected to the bottom of the workbench 2. A handle 7 is fixedly connected to the left end of the caliper 6.

[0026] Specifically, the support rod 10 at the top of the positioning plate 29 is vertically set, and the outer wall is engraved with scale 11. The clamping plate 13 is sleeved on the support rod 10 and can slide up and down. The top is provided with a limiting plate 12 to prevent the clamping plate 13 from falling off. Then, pull the clamping plate 13 upward to a position higher than the top of the wheel hub body 3, and rotate the clamping plate 13 to place it horizontally on the top of the wheel hub. By observing the position of the clamping plate 13 on the support rod 10 and reading the value of scale 11, the wheel hub thickness can be obtained. When it is necessary to disassemble the laser rangefinder 21, pull the limiting frame 18 upward, which will drive the sliding rod 25 and the limiting plate 26 to move upward along the inner wall of the fixing frame 14, compressing the spring 2 17, thus widening the distance between the limiting frame 18 and the fixing frame 14, releasing the clamping force on the laser rangefinder 21. The laser rangefinder 21 can be removed from between the two. After maintenance, pull the limiting frame 18 upward again to place the laser rangefinder 21 back between the fixed frame 14 and the limiting frame 18. Release the limiting frame 18, and the spring 17 will reset and push the limiting frame 18 downward. The laser rangefinder 21 is elastically clamped by the pad 20 to ensure that it is stable and does not shake. The pad 20 is made of rubber to provide a buffer for the laser rangefinder 21, avoid hard contact that could damage the instrument, and enhance the clamping seal. The guide rod 19 is fixed to the bottom of the limiting frame 18 and inserted into the inner wall groove of the fixed frame 14 to further enhance the stability of the limiting frame 18 when sliding and prevent tilting. The limiting plate 12 is fixed to the top of the support rod 10 to prevent the clamping plate 13 from slipping upward.

[0027] Working principle: Pulling handle 7 moves caliper 6 and compresses spring 5, then places the wheel hub body 3 on the workbench 2, pressing it tightly against positioning plate 8 and positioning plate 9. Positioning plate 8 and positioning plate 9 position the wheel hub body 3. Then, releasing the force applied to handle 7 allows spring 5 to spring caliper 6 to the wheel hub body 3, clamping it with caliper 6 and positioning plate 9. Then, the laser rangefinder 21 is activated, and the ranging laser emitted by the laser rangefinder 21 hits the distance plate 22. The distance between the laser rangefinder 21 and the distance plate 22 is the diameter of the wheel hub body 3. Then, drag the clamping plate 13 upward and rotate it, placing the clamping plate 13 on top of the wheel hub body 3. At the end, observe the position of the clamping plate 13 on the support rod 10, and the thickness of the wheel hub body 3 can be determined by the scale 11. When it is necessary to disassemble the laser rangefinder 21, simply pull the limiting frame 18 upward, which will drive the sliding rod 15 and the limiting plate 16 to move and compress the spring 17, thereby removing the limiting of the laser rangefinder 21 and removing the laser rangefinder 21 from the fixing frame 14 and the limiting frame 18. After the maintenance of the laser rangefinder 21 is completed, pull the limiting frame 18 upward again to place the laser rangefinder 21 between the fixing frame 14 and the limiting frame 18. Then, release the force applied to the limiting frame 18. Under the action of the spring 17, the limiting frame 18 can move downward to clamp and fix the laser rangefinder 21.
