Description

Technical Field

[0001] This utility model relates to a grinding device, and more particularly to an auxiliary grinding device for aluminum wheel hub production. Background Technology

[0002] As a key component of automobiles, the surface quality of wheel hubs directly affects the aesthetics and safety of the entire vehicle. In the production process of aluminum wheel hubs, grinding is an important finishing step, used to remove burrs, oxide layers, and surface defects, improving the wheel hub's smoothness and coating adhesion.

[0003] Currently, traditional grinding operations for aluminum wheels are still primarily manual: operators place the wheel on a simple grinding stand and use hand-held grinding tools (such as angle grinders and polishers) to grind the surface. However, due to the operator's arm range of motion and operating habits, a single grinding session can only cover a localized area of ​​the wheel. Therefore, after grinding a single area, the wheel must be frequently rotated to switch to the next area to be processed. Because the grinding intervals between adjacent areas are short, in pursuit of operational convenience and to accommodate rapid adjustments, operators often skip the step of using a fixing clamp and instead temporarily position the wheel by pressing it with their hands or leaning against it. While this method allows for rapid free rotation of the wheel, it sacrifices stability, causing the wheel to wobble or even slip, affecting grinding accuracy and safety. Furthermore, prolonged manual fixing of the wheel significantly increases the operator's physical exertion, leading to increased fatigue, reduced production efficiency, and potentially affecting the final quality of the wheel due to unstable operation.

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] This embodiment mainly describes the structure of the grinding device, as follows: An auxiliary grinding device for aluminum wheel hub production, see reference. Figures 1-3The system includes: a support 1; a support plate 2 mounted on the support 1 for placing the aluminum wheel hub; a motor 4 fixedly installed at the lower center of the support plate 2; a control plate 5 rotatably installed at the lower center of the support plate 2, the output end of the motor 4 being coaxially and fixedly connected to the control plate 5 to drive the control plate 5 to rotate, the control plate 5 having six guide grooves evenly arranged on it; and six sets of limit arms 6 slidably mounted on the support plate 2, each set of limit arms 6 corresponding to each guide groove. When the control plate 5 rotates, it will drive all the limit arms 6 to move synchronously along the radial direction of the support plate 2 through the guide grooves. The roller 7 is rotated and mounted on the limit arm 6; the rubber sleeve 19 is fixedly mounted on the outer layer of the roller 7 to buffer the contact pressure through elastic deformation and avoid direct contact between the roller 7 and the aluminum hub, which would cause scratches; the control switch 20 is fixedly mounted on the support 1. The control switch 20 is electrically connected to the motor 4. The control switch 20 has two control units for forward and reverse rotation, which are used to control the output shaft of the motor 4 to rotate clockwise and counterclockwise, respectively. The control switch 20 adopts a push-button control structure and is located at the lower part of the support 1 and is triggered by the foot.

[0020] In use, the center of the aluminum hub is passed through all the limiting arms 6. The operator steps on and continuously presses the forward rotation control unit of the control switch 20, causing the control panel 5 to be driven to rotate forward by the motor 4. The limiting arms 6 are radially separated until the rubber sleeve 19 is in close contact with the inner wall of the aluminum hub. The operator then releases the control switch 20 to stop the motor 4, allowing the aluminum hub to be stably fixed by the limiting arms 6. When switching areas after grinding the aluminum hub, the operator briefly steps on the reverse rotation control unit of the control switch 20. The motor 4 reverses, causing the limiting arms 6 to slightly loosen but not completely release the constraint on the aluminum hub, allowing the aluminum hub to rotate with the assistance of the roller 7 and maintain a stable position. After adjustment, the operator briefly steps on the forward rotation control unit of the control switch 20 to drive the limiting arms 6 to re-fix the aluminum hub. This cycle is repeated until all areas of the aluminum hub have been ground. Finally, the operator continuously steps on the reverse rotation switch to retract the limiting arms 6 for easy removal of the aluminum hub.

[0021] This device uses a control panel 5 to control the synchronous extension and retraction of the limit arm 6. Combined with a push-button control switch 20, it transforms complex fixing and disassembly requirements into a simple "press-release" action, conveniently switching the tension of the limit arm 6. In conjunction with the use of the roller 7, it facilitates the fixing and unlocking of aluminum wheel hubs and the switching of the grinding area of ​​the aluminum wheel hub, adapting to fast-paced grinding operations and improving the applicability of this device. In addition, it is compatible with aluminum wheel hubs of different sizes, further enhancing the applicability of this device. The control switch 20 is set to foot operation, improving the ease of use for the operator.

[0022] See Figure 1 , Figure 2 and Figure 4The device also includes: a hinge seat 8 fixedly installed on the support 1 and the support plate 2 respectively; a cylinder 9 rotatably installed on the hinge seat 8 of the support 1; a connecting arm 10 rotatably installed on the hinge seat 8 of the support plate 2, with the telescopic rod end of the cylinder 9 fixed to the connecting arm 10; and a rotating shaft 11 fixedly installed on the support 1, with the support plate 2 rotatably installed on the support 1 via the rotating shaft 11.

[0023] By controlling the extension and retraction of cylinder 9, the connecting arm 10 is displaced, which in turn pushes the support plate 2 to rotate around the rotation axis 11. During this process, cylinder 9 rotates relative to support 1, and connecting arm 10 also rotates relative to support plate 2, thus achieving flexible adjustment of the angle of support plate 2. In this way, the operator can adjust the angle of support plate 2 at any time according to their own operating habits and work needs, thereby obtaining a more comfortable operating posture, effectively reducing fatigue during long-term aluminum wheel hub grinding operations, and improving the convenience and comfort of operation.

[0024] See Figure 1 and Figure 2 The device also includes: a guide surface 3 fixedly installed on the lower part of the support plate 2; a guide hood 12 fixedly installed on the lower part of the guide surface 3, the guide hood 12 being funnel-shaped; a vacuum cleaner 14 fixedly installed on the support 1 for adsorbing grinding debris; a hose 13 fixedly installed between the guide hood 12 and the vacuum cleaner 14; a filter screen 15 fixedly installed at the funnel opening of the guide hood 12; and a retaining ring 16 fixedly installed on the upper outer edge of the support plate 2.

[0025] During operation, the vacuum cleaner 14 generates airflow upon startup. The dust generated during grinding is guided by the airflow through the guide surface 3 into the guide hood 12, and then through the hose 13 into the vacuum cleaner 14. This reduces the impact of dust on the operator's health and interference with the operation, improving the safety of the grinding operation and reducing dust dispersion pollution of the working environment. The guide surface 3 and the funnel-shaped guide hood 12 work together to concentrate the dust, making the vacuum cleaner 14's adsorption effect more significant and effectively reducing the dispersion of dust in the work area. The filter 15 at the funnel opening of the guide hood 12 can intercept large impurities, preventing them from entering the vacuum cleaner 14 and causing blockages, ensuring the normal operation of the vacuum cleaner 14. The retaining ring 16 on the outer edge of the support plate 2 is used to prevent dust from flowing downwards along the inclined surface of the support plate 2, thus preventing dust leakage outside the device and further improving the comprehensiveness of dust collection.

[0026] See Figure 1 and Figure 2The device also includes: handles 17 fixedly installed on both sides of the support 1; and anti-slip pads 18 fixedly installed on the bottom of the support 1. Using handles 17 improves the flexibility and convenience of moving the device; using anti-slip pads 18 increases contact friction with the ground, effectively preventing the device from sliding or shifting due to external impacts or operational vibrations when it is freely moved and placed, ensuring the device remains stable during operation and providing stable support for aluminum wheel hub grinding.
