Description

Technical Field

[0001] This utility model belongs to the field of automotive wheel hub protection technology, specifically a protective tool for aluminum alloy wheels. Background Technology

[0002] Aluminum alloy wheels are widely used in the automotive manufacturing industry due to their advantages such as light weight, high strength, good heat dissipation, and aesthetic appeal. However, aluminum alloys are susceptible to corrosion from oxygen and moisture in the air during long-term use, leading to surface oxidation and corrosion, which affects the wheel's lifespan and appearance. To improve the corrosion resistance and decorative effect of aluminum alloy wheels, a coating process is usually applied to their surface. This coating not only effectively blocks air and moisture but also enhances the wheel's wear resistance and impact resistance.

[0003] However, in the current spraying process, most can only protect the wheel hub holes one by one, and cannot effectively seal multiple wheel hub holes on the same wheel at the same time, resulting in low production efficiency. Due to improper protection, the sprayed wheel products often have defects such as powder accumulation on the inner wall of the holes and peeling of the spray coating, which directly affects the yield rate of the products. Utility Model Content

[0004] The purpose of this utility model is to provide a protective tool for spraying aluminum alloy wheels, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] A protective fixture for aluminum alloy wheel spraying is provided, including a mounting base. Several support frames are arranged on the upper part of the mounting base along the circumferential direction. The support frames are provided with sliding grooves. A slider is slidably connected inside the sliding groove. Each slider is provided with a protective component. Several clamping components are arranged on the mounting base along the circumferential direction.

[0006] Furthermore, the upper part of the support frame is provided with several mounting holes, the slider is provided with locking holes, and the support frame is provided with fastening bolts for passing through the mounting holes and locking holes. After the support frame is adjusted to a suitable position, it can be firmly locked by fastening bolts passing through the mounting holes and locking holes to prevent positional displacement during the spraying process. After the fastening bolts pass through the mounting holes and locking holes, they can provide strong clamping force to prevent the support frame from vibrating or loosening during the spraying process.

[0007] Furthermore, the protective component includes a protective rod body mounted on a slider. A protective plate body is located below the protective rod body, and an electric push rod is located at the bottom of the protective plate body. A positioning pin block is fixedly connected to the telescopic end of the electric push rod. A rubber pad block is provided at the bottom of each positioning pin block. The slider can move along the slide groove, driving the entire protective component to move. This allows the protective component to move flexibly to different hole positions on the wheel. Through the telescopic action of the electric push rod, the positioning pin block is precisely pressed into the hole to achieve a sealing effect. When the positioning pin block is pressed into the hole, the rubber pad block can prevent the positioning pin block from directly contacting the surface of the aluminum alloy wheel, preventing direct contact between hard materials from causing scratches or damage to the wheel surface.

[0008] Furthermore, both sides of the bottom plate of the positioning pin block are provided with inclined guide surfaces. When the electric push rod pushes the positioning pin block to move downward, the inclined guide surfaces can guide the pin block to gradually fit into the edge of the hole and enter, so as to avoid the positioning pin block scratching the edge of the aluminum alloy wheel hole due to excessive friction when it is inserted.

[0009] Furthermore, the clamping assembly includes a clamping seat, which is mounted on a mounting base. A clamping screw is rotatably connected to the clamping seat, and a clamping arc plate is fixedly connected to the clamping screw. By rotating the clamping screw, its axial movement can be controlled, thereby driving the clamping arc plate to clamp the inner wall of the wheel outward. The clamping arc plate can better fit the inner wall of the wheel, increase the contact area, and avoid stress concentration or damage to the wheel surface caused by point contact.

[0010] Furthermore, each of the tightening arc plates is provided with a rubber layer, so that when the tightening arc plate comes into contact with the inner wall of the wheel, it becomes a flexible contact rather than a rigid contact. The rubber material has good elasticity and cushioning performance.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] With the manual rotation and locking mechanisms, operators can easily adjust the angle of the oil tank, ensuring that all areas of the inner wall and internal pipes of the oil tank are sprayed. The limiting and locking mechanisms ensure that the oil tank remains stable during rotation and spraying, preventing the oil tank from moving or shaking, thus improving spraying stability. Through the rotation and locking functions, operators can quickly adjust the angle of the oil tank, avoiding frequent handling and movement of the oil tank during manual spraying, making operation convenient and improving spraying efficiency.

This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0022] Please see Figure 1-4 As shown in the embodiment of this utility model, an aluminum alloy wheel spraying protective fixture includes a mounting base 1, a plurality of support frames 2 are arranged on the upper part of the mounting base 1 along the circumferential direction, a sliding groove 21 is provided on the support frame 2, a slider 22 is slidably connected inside the sliding groove 21, a protective component 3 is provided on the slider 22, and a plurality of clamping components 4 are arranged on the mounting base 1 along the circumferential direction.

[0023] The mounting base 1 has several support frames 2 arranged along the circumference. The position of the support frames 2 can be adjusted by sliding the sliding groove 21 and the slider 22. This allows the position of the support frames 2 to be adjusted according to the different sizes of aluminum alloy wheels, ensuring that the support frames can accurately fit the outer contour of the wheel and provide stable support and positioning. The slider 22 on the support frame 2 is equipped with a protective component 3. The protective component 3 can move to the hole position on the wheel to be painted and seal it. The main function of the protective component 3 is to prevent paint from entering the hole on the wheel to be painted during the painting process, keeping the hole clean and dimensionally accurate, thereby avoiding problems in subsequent processing or assembly. During the process of sealing the hole, the clamping component 4 can effectively prevent the wheel from shifting or shaking, ensuring that the painting process is uniform and stable, improving the painting quality, and ensuring that the paint only covers the surface of the wheel during the painting process and does not enter the hole or cause the wheel to shift, thereby greatly improving the painting quality and efficiency and reducing the need for subsequent cleaning or rework.

[0024] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The upper part of the support frame 2 is provided with several mounting holes 23, and the slider 22 is provided with locking holes 221. The support frame 2 is provided with fastening bolts for passing through the mounting holes 23 and locking holes 221. After the support frame 2 is adjusted to a suitable position, it can be firmly locked by fastening bolts passing through the mounting holes 23 and locking holes 221 to prevent position displacement during the spraying process. After the fastening bolts pass through the mounting holes 23 and locking holes 221, they can provide a strong clamping force to prevent the support frame 2 from vibrating or loosening during the spraying process.

[0025] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The protective component 3 includes a protective rod body 31, which is mounted on the slider 22. A protective plate body 32 is located below the protective rod body 31, and an electric push rod 33 is located at the bottom of the protective plate body 32. A positioning pin block 34 is fixedly connected to the telescopic end of the electric push rod 33, and rubber pads 35 are provided at the bottom of each positioning pin block 34. The protective component 3 includes the protective rod body 31, the protective plate body 32, the electric push rod 33, the positioning pin block 34, and the rubber pads 35. The protective rod body 31 is fixed to the slider 22, and the slider 22 can move along the slide groove 21. The entire protective assembly 3 is moved so that it can be flexibly moved to different hole positions on the wheel. The positioning pin 34 is precisely pressed into the hole by the extension and retraction of the electric push rod 33 to achieve a sealing effect. When the positioning pin 34 is pressed into the hole, the rubber pad 35 can fill the tiny gaps at the edge of the hole to prevent the sprayed material from seeping into the hole and ensure that the hole is completely sealed. The rubber material is soft and can prevent the positioning pin 34 from directly contacting the surface of the aluminum alloy wheel, thus preventing the wheel surface from being scratched or damaged by direct contact between hard materials.

[0026] Specifically, in one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 Both sides of the base plate of the positioning pin block 34 are provided with inclined guide surfaces 341. When the electric push rod 33 pushes the positioning pin block 34 to move downward, the inclined guide surfaces 341 can guide the pin block to gradually fit into the edge of the hole and enter, so as to avoid the positioning pin block 34 from scratching the edge of the aluminum alloy wheel hole due to excessive friction when it is inserted.

[0027] Further, please refer to Figure 1 and Figure 4 The clamping assembly 4 includes a clamping seat 41, which is mounted on the mounting base 1. A clamping screw 42 is rotatably connected to the clamping seat 41, and a clamping arc plate 43 is fixedly connected to the clamping screw 42. By rotating the clamping screw 42, its axial movement can be controlled, thereby driving the clamping arc plate 43 to clamp the inner wall of the wheel outward. The clamping arc plate 43 is designed in an arc shape. The arc design can better fit the inner wall of the wheel, increase the contact area, and avoid stress concentration or damage to the wheel surface caused by point contact.

[0028] Please see Figure 1 and Figure 4 Each of the tightening arc plates 43 is provided with a rubber layer 431. The rubber layer 431 on the tightening arc plate 43 makes the tightening arc plate 43 make flexible contact rather than rigid contact when it comes into contact with the inner wall of the wheel. The rubber material has good elasticity and cushioning performance.

[0029] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
