Description

Technical Field

[0001] This utility model relates to the field of rust removal and polishing technology, and in particular to a rust removal and polishing device for the surface of steel wheels. Background Technology

[0002] As a key component for vehicle load-bearing and driving, steel wheels are exposed to complex outdoor environments for extended periods, making them susceptible to rust due to rainwater, salt, dust, and other corrosive substances. Rust gradually erodes the metal substrate of the steel wheel, resulting in thinner wheel walls and damage to its structural integrity.

[0003] However, in existing technologies, traditional wheel grinding equipment often uses simple mechanical clamping and positioning, which makes it difficult to control the clamping force. Furthermore, under the influence of grinding vibration, wheel displacement and shaking are prone to occur. This not only leads to a decrease in grinding accuracy and over- or under-grinding, but also easily causes safety accidents, increases rework costs and operation time. In addition, the grinding angle is fixed or has a limited adjustment range. When faced with complex structures such as wheel edge curvature and surface concavity, grinding dead corners are easy to occur, resulting in uneven grinding of the wheel surface, affecting the appearance and performance, and failing to meet the requirements of high-quality grinding. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology that often use simple mechanical clamping and positioning, which makes it difficult to control the clamping force and easily causes wheel displacement and shaking under the influence of grinding vibration. Therefore, this invention proposes a rust removal and grinding device for steel wheels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel wheel surface rust removal and grinding device, including a support plate, a third cylinder installed at the bottom end of the support plate, a first moving component fixedly connected to the output end of the third cylinder, an offset mechanism provided on one side of the support plate, and a positioning mechanism installed on the inner side of the top of the offset mechanism. The offset mechanism includes a base plate and a movable plate. The base plate has multiple support frames symmetrically fixedly connected to its top. Multiple second cylinders are arranged between the base plate and the movable plate. Both points of the second cylinders are rotatably connected to universal joints. One universal joint is rotatably connected to the support frame, and the other universal joint is rotatably connected to a connecting frame on its outer side. The top of the connecting frame is fixedly connected to the bottom of the movable plate. The positioning mechanism includes a lifting plate and a fixed plate. A first cylinder is fixedly connected to the center of the bottom of the lifting plate, and multiple lifting rods are slidably connected to the outer edge of the fixed plate. The bottom ends of the lifting rods are fixedly connected to the lifting plate.

[0006] Preferably, the outer edge of the fixed plate is fixedly connected to the inner wall of the movable plate, and a placement platform is fixedly connected to the top center of the fixed plate.

[0007] Preferably, multiple positioning frames are rotatably connected to the outer edge of the placement platform, and a positioning block is fixedly connected to one end of each positioning frame.

[0008] Preferably, the top of the lifting rod passes through the fixed plate, and the inner side of the top of the lifting rod is rotatably connected to the positioning frame.

[0009] Preferably, the top of the support plate is provided with a sliding groove, which is slidably connected to one end of the first moving component.

[0010] Preferably, the first moving component is driven to a second moving component, and the second moving component is driven to a grinding machine.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the wheel is positioned by the linkage of the first cylinder, the lifting plate, the lifting rod, the positioning frame and the positioning block, and the wheel can be firmly fixed, preventing displacement and shaking during grinding. This not only avoids grinding deviation caused by wheel movement and reduces rework, but also provides a reliable basis for subsequent angle adjustment and position adjustment, ensuring that the grinding operation is carried out in an orderly manner in a stable environment, and ensuring the safety and continuity of the operation. 2. In this invention, the second cylinder, in conjunction with a universal joint, allows the movable plate to be flexibly adjusted in angle, ensuring that the grinding tool covers all areas of the wheel, avoiding grinding dead spots and uneven grinding in certain areas. The third cylinder and the moving component form a multi-level adjustment system, which can precisely adjust the position of the grinder, reduce ineffective movement time, and avoid errors caused by positional deviations. The combination of these two systems ensures the completeness of the grinding process, improves work efficiency, reduces costs, and shortens the cycle time. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] 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.

[0016] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a steel wheel surface rust removal and grinding equipment, including a support plate 1, a third cylinder 7 installed at the bottom end of the support plate 1, a first moving component 2 fixedly connected to the output end of the third cylinder 7, an offset mechanism 6 provided on one side of the support plate 1, and a positioning mechanism 5 installed on the inner side of the top of the offset mechanism 6. The offset mechanism 6 includes a base plate 61 and a movable plate 66. The base plate 61 has multiple support frames 63 symmetrically fixedly connected to its top. Multiple second cylinders 62 are arranged between the base plate 61 and the movable plate 66. Both points of the second cylinders 62 are rotatably connected to universal joints 64. One universal joint 64 is rotatably connected to the support frame 63, and the other universal joint 64 is rotatably connected to a connecting frame 65 on its outer side. The top of the connecting frame 65 is fixedly connected to the bottom of the movable plate 66. The positioning mechanism 5 includes a lifting plate 51 and a fixed plate 53. A first cylinder 52 is fixedly connected to the center of the bottom of the lifting plate 51, and multiple lifting rods 54 are slidably connected to the outer edge of the fixed plate 53. The bottom end of the lifting rods 54 is fixedly connected to the lifting plate 51.

[0017] The specific setup and function of this embodiment will be described in detail below. During the positioning and grinding process of the wheel, the wheel to be processed must first be stably placed on the placement platform 55 located at the top of the equipment. To ensure the positioning accuracy and stability of the wheel during the subsequent grinding process, a coordinated control lifting and positioning structure is adopted. When the first cylinder 52 is activated and drives the lifting plate 51 to move vertically upward, multiple lifting rods 54 mounted on the lifting plate 51 will rise synchronously. A mechanical linkage mechanism is provided between the upper end of the lifting rod 54 and the positioning frame 56. Therefore, during the upward movement of the lifting rod 54, it will apply an axial force to the positioning frame 56, thereby driving the positioning frame 56 to rotate around its central axis.

[0018] As multiple positioning frames 56 simultaneously rotate at a certain angle, the positioning blocks 57 fixedly mounted on them move closer to the circumferential edge of the wheel and make contact and press, forming an effective clamping and positioning of the wheel's circumferential position. This multi-point compression positioning method can effectively prevent the wheel from making micro-movements or shifts in a high-frequency vibration environment, ensuring the high stability of the wheel's position and the processing accuracy during the grinding operation.

[0019] In the actual grinding process, to further improve the coverage and comprehensiveness of the grinding operation, multiple adjustable mechanisms driven by second cylinders 62 are installed. The second cylinders 62 and the movable plate 66 are mechanically connected via universal joints 64, allowing the movable plate 66 to be adjusted with multiple degrees of freedom in space. When the second cylinders 62 extend or retract, the transmission characteristics of the universal joints 64 drive the movable plate 66 to offset or tilt in multiple directions. Through the coordinated control of multiple second cylinders 62, the spatial posture of the movable plate 66 can be precisely adjusted, allowing the grinding tool to more flexibly contact different areas of the wheel surface, ensuring that every corner is thoroughly ground, improving the consistency of the grinding effect and the uniformity of the surface quality.

[0020] Example 2: Figure 2 - Figure 4 As shown, the outer edge of the fixed plate 53 is fixedly connected to the inner wall of the movable plate 66, and a placement platform 55 is fixedly connected to the top center of the fixed plate 53. Multiple positioning frames 56 are rotatably connected to the outer edge of the placement platform 55, and a positioning block 57 is fixedly connected to one end of each positioning frame 56. The top end of the lifting rod 54 passes through the fixed plate 53, and the inner side of the top end of the lifting rod 54 is rotatably connected to the positioning frame 56. A sliding groove is provided at the top end of the support plate 1, and the sliding groove is slidably connected to one end of the first moving component 2. The first moving component 2 is drivenly connected to the second moving component 3, and the second moving component 3 is drivenly connected to the grinder 4.

[0021] The overall effect of this embodiment is that, during the grinding process, the third cylinder 7 drives the first moving component 2 to move up and down. This vertical drive allows for precise adjustment of the grinding device's height, adapting to wheel surfaces of different sizes or wear levels. The first moving component 2 not only has vertical movement capability but also serves as a platform, providing lateral movement support for the second moving component 3. Through the structural design of the first component and the coordination of the guiding mechanism, the second moving component 3 can move smoothly in the horizontal direction, thereby further expanding the working coverage of the grinding head.

[0022] Based on this, the second moving component 3 adjusts the position of the grinder 4 through its built-in drive mechanism to ensure that the grinding head always maintains a suitable contact angle and pressure with the target grinding surface of the wheel. This multi-dimensional linkage drive structure enables the grinder 4 to flexibly cope with different grinding needs of parts such as wheel rims and flanges, avoiding uneven grinding or low efficiency caused by fixed angles or positions.

[0023] The usage and working principle of this device are as follows: In the wheel positioning and grinding operation, the wheel is first placed on the top of the placement platform 55. Then, the first cylinder 52 drives the lifting plate 51 to move upward, which drives multiple lifting rods 54 to move upward synchronously. The lifting rods 54 apply force to the positioning frame 56 to make it rotate. When multiple positioning frames 56 rotate together, the wheel edge is squeezed and positioned by the positioning block 57 to ensure that the wheel does not move during the grinding process. The extension and retraction action of the second cylinder 62, in conjunction with the universal joint 64, drives the movable plate 66 to move. Under the coordinated drive of multiple second cylinders 62, the offset angle of the movable plate 66 can be flexibly adjusted. At the same time, the third cylinder 7 drives the first moving component 2 to move up and down. The first moving component 2 drives the second moving component 3 to move. The second moving component 3 further precisely adjusts the position of the grinding machine 4 to adapt to the grinding needs of different parts of the wheel.

[0024] 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.
