Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, specifically to a surface grinding device for automotive bearing processing. Background Technology

[0002] Automotive bearings are core components that support rotating parts and reduce friction, widely used in wheels, engines, transmissions, and other parts. Their structure typically consists of an inner ring, outer ring, rolling elements, and a cage. They replace sliding friction with rolling friction, significantly reducing energy loss. The materials are mostly high-carbon chromium bearing steel, which, after quenching and tempering, possesses high hardness, wear resistance, and fatigue resistance, enabling it to withstand radial and axial loads and complex stresses. In the manufacturing process of automotive bearings, surface grinding is a critical step. This is because grinding is a core process ensuring the bearing's precision, reliability, and durability, directly affecting the vehicle's power transmission efficiency and driving safety.

[0003] Patent CN220145435U discloses a bearing outer surface grinding device for bearing processing. The device includes a frame, a fixed column fixedly connected to one side of the top surface of the frame, a retaining seat fixedly connected to the middle of the bottom inner side of the fixed column, a threaded rod rotatably connected to the middle inner side of the retaining seat, a slider threadedly connected to the outer side of the middle of the threaded rod, a connecting column fixedly connected to one side of the slider, a motor fixedly connected to the bottom inner side of the connecting column, a rotating shaft fixedly connected to the motor drive end, and the end of the rotating shaft away from the motor fixedly connected to the middle of one side surface of a turntable. This device, by rotating a handle, drives the threaded rod to rotate within a limited position on the retaining seat, causing the slider to move up and down, thereby causing the connecting column fixed on the slider to move up and down synchronously. This facilitates quick position adjustment for grinding work and allows for quick resetting after grinding.

[0004] While the above-mentioned device can quickly fix and remove bearings, it still has the following shortcomings:

[0005] During the bearing grinding process, a large amount of metal shavings are generated. These metal shavings can splash onto the equipment surface, frame gaps, or workshop environment, not only polluting the operating environment, but also causing the equipment transmission components to jam due to the accumulation of shavings, and even being inhaled by operators, which can endanger their health. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a surface grinding device for automotive bearing processing, which can collect and clean up metal shavings generated during bearing processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a surface grinding device for processing automotive bearings, comprising a worktable, symmetrically arranged transport rollers on the worktable, guide rollers with bearings fixed between the transport rollers, a grinding machine on the left side of the worktable, a debris collection screen on the top surface of the worktable, transport rollers mounted on the top surface of the debris collection screen, a negative pressure collection component on the bottom surface of the debris collection screen, a transport cleaning component on the top surface of the worktable outside the transport rollers, and a bearing cleaning component on the top surface of the debris collection screen directly below the guide rollers.

[0008] Furthermore, the negative pressure collection assembly includes an inclined collection trough located below the debris collection mesh plate, with a discharge port on the bottom surface of the inclined collection trough, and the discharge port is connected to an industrial vacuum cleaner.

[0009] Furthermore, the transport cleaning component includes mounting frames symmetrically arranged on the top surface of the workbench. The mounting frames are located outside the transport rollers. The mounting frames are equipped with placement racks inclined towards the transport rollers. Transport cleaning brushes are mounted on the placement racks by mounting bolts, and the ends of the transport cleaning brushes are in contact with the transport rollers.

[0010] Furthermore, the bearing cleaning assembly includes an extension frame fixedly mounted on the top surface of the debris collection mesh plate. A T-shaped slide bar is provided on the top surface of the extension frame. Bearing cleaning brushes are slidably connected to the T-shaped slide bar from left to right. The top surface of the bearing cleaning brushes is in contact with the bottom surface of the guide roller. The front side of the extension frame extends upward. A fixing block is bolted to the rear end of the extension frame. The fixing block is attached to the rear side of the last bearing cleaning brush.

[0011] Furthermore, the inclined collection trough is equipped with negative pressure suction ports in the middle of all four sides, and the negative pressure suction ports are connected to the industrial vacuum cleaner through auxiliary suction pipes.

[0012] Furthermore, a horizontal limiting opening is provided on the inner side of the lower end of the transport cleaning brush, and a limiting plate that works in conjunction with the limiting opening is provided on the inner side of the placement rack.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up a debris collection mesh and negative pressure collection components, metal debris generated during grinding can be adsorbed in real time, preventing debris from splashing and polluting the environment or damaging the bearing surface. By setting up a transport cleaning component, residual debris on the roller surface can be continuously removed during bearing transport, preventing secondary contamination of the bearing or affecting grinding accuracy. By setting up a bearing cleaning component, it is ensured that there are no residual debris on the bearing surface on the guide roller before and after grinding. By setting up a negative pressure dust suction port and an auxiliary dust suction pipe, not only can the dust suction coverage be expanded and the debris collection efficiency be improved, but the negative pressure distribution can also be balanced to maintain stable suction. By setting up a limiting port and a limiting plate, it is easy to disassemble and replace, and it can also prevent loosening due to vibration during operation, ensuring stable cleaning effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a surface polishing device for processing automotive bearings includes a worktable 1, on which transport rollers 2 are symmetrically arranged, and between the transport rollers 2, a guide roller 3 for fixing the bearing is placed. A polishing machine 4 is arranged on the left side of the worktable 1. A debris collection screen 5 is arranged on the top surface of the worktable 1. The transport rollers 2 are mounted on the top surface of the debris collection screen 5. A negative pressure collection component 6 is arranged on the bottom surface of the debris collection screen 5. A transport cleaning component 7 is arranged on the top surface of the worktable 1 outside the transport rollers 2. A bearing cleaning component 8 is arranged on the top surface of the debris collection screen 5 directly below the guide roller 3.

[0023] like Figure 1As shown, the bearing grinding equipment in this utility model is structurally similar to existing bearing grinding equipment. For example, patent CN220145435U discloses a bearing outer surface grinding equipment for bearing processing. The main improvement of this utility model is that it can collect and clean the metal shavings generated during bearing processing. Figures 1 to 5 As shown, this utility model discloses a surface grinding device for processing automotive bearings. During use, the guide roller 3 moves forward at a constant speed under the drive of the transport roller 2. During the forward movement of the guide roller 3, the grinding machine 4 grinds the bearings on the guide roller 3. During the grinding process, the transport cleaning brush 704 installed on the placement frame 702 cleans the transport roller 2. The transport cleaning brush 704, which is attached to the lower outer side of the transport roller 2 and tilts inward, sweeps the metal debris attached to the transport roller 2 onto the debris collection screen 5, thus cleaning the transport roller 2. At the same time, the bearing cleaning brush 803, which is placed horizontally back and forth, is attached to the bearings on the guide roller 3 and sweeps them, causing the metal debris attached to the bearings to fall onto the debris collection screen 5, thus cleaning the bearings. Subsequently, the cleaned-out metal shavings, along with the metal shavings generated from grinding, will fall from the shavings collection mesh 5 and, under the negative pressure suction of the industrial vacuum cleaner 603, enter the industrial vacuum cleaner 603 through the inclined collection trough 601, the discharge port 602, and the negative pressure suction port 604, thus completing the collection of the metal shavings.

[0024] like Figure 2 As shown, the negative pressure collection assembly 6 includes an inclined collection trough 601 disposed below the debris collection mesh plate 5. The bottom surface of the inclined collection trough 601 is provided with a discharge port 602, and the discharge port 602 is connected to an industrial vacuum cleaner 603.

[0025] Specifically, as the grinder 4 grinds the bearing fixed on the guide roller 3, the industrial vacuum cleaner 603 will also start working. The negative pressure suction generated by the cleaner will guide the metal debris generated by the grinding to fall down and be collected into the discharge port 602 through the debris collection mesh 5 and the inclined collection trough 601, and finally enter the industrial vacuum cleaner 603 to complete the collection of metal debris.

[0026] like Figures 2 to 4 As shown, the transport cleaning assembly 7 includes a mounting frame 701 symmetrically arranged on the top surface of the workbench 1. The mounting frame 701 is located on the outside of the transport roller 2. The mounting frame 701 is provided with a placement frame 702 inclined towards the transport roller 2. Several transport cleaning brushes 704 are mounted on the placement frame 702 by mounting bolts 703. The ends of the transport cleaning brushes 704 are in contact with the transport roller 2.

[0027] Specifically, as the grinder 4 grinds the bearings fixed on the guide roller 3, the guide roller 3 will move forward at a constant speed under the drive of the transport roller 2. During the rotation of the transport roller 2, the transport cleaning brush 704 installed on the placement frame 702 will clean the transport roller 2. The transport cleaning brush 704, which is attached to the lower outer side of the transport roller 2 and tilted inward, will sweep the metal debris attached to the transport roller 2 onto the debris collection screen 5, thus cleaning the transport roller 2. When the transport cleaning brush 704 needs to be replaced due to wear or damage, the operator can replace it by removing the mounting bolt 703, which is simple and convenient.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the bearing cleaning assembly 8 includes an extension frame 801 fixedly mounted on the top surface of the debris collection mesh plate 5. A T-shaped slide bar 802 is provided on the top surface of the extension frame 801. Several bearing cleaning brushes 803 are slidably connected to the T-shaped slide bar 802. The top surface of the bearing cleaning brushes 803 is in contact with the bottom surface of the guide roller 3. The front side of the extension frame 801 extends upward. The rear end of the extension frame 801 is connected to a fixing block 804 by bolts. The fixing block 804 is attached to the rear side of the last bearing cleaning brush 803.

[0029] Specifically, as the grinder 4 grinds the bearing fixed on the guide roller 3, the guide roller 3 moves backward at a constant speed under the drive of the transport roller 2. During the forward movement of the guide roller 3, the bearing cleaning brush 803, which is placed horizontally back and forth, comes into contact with the bearing on the guide roller 3 and cleans it, causing the metal debris attached to the bearing to fall onto the debris collection screen 5, thus cleaning the bearing. When the bearing cleaning brush 803 needs to be replaced due to wear or damage, the operator can remove the fixing block 804 and bolts to remove the bearing cleaning brush 803 slidably connected to the T-shaped slide bar 802, and replace the transport cleaning brush 704.

[0030] like Figure 2 As shown, the inclined collection trough 601 has a negative pressure suction port 604 in the middle of each of its four sides. The negative pressure suction port 604 is connected to the industrial vacuum cleaner 603 through an auxiliary suction pipe 605.

[0031] Specifically, by setting a negative pressure suction port 604 on the side of the inclined collection trough 601, and connecting the negative pressure suction port 604 to the industrial vacuum cleaner 603 through the auxiliary suction pipe 605, not only can the suction coverage be expanded and the debris collection efficiency be improved, but also the negative pressure distribution can be balanced to maintain stable suction.

[0032] like Figure 3 and Figure 4As shown, a horizontal limiting opening 705 is provided on the inner side of the lower end of the transport cleaning brush 704, and a limiting plate 706 is provided on the inner side of the placement rack 702 to cooperate with the limiting opening 705.

[0033] Specifically, with the cooperation of the limiting port 705 and the limiting plate 706, it is convenient to disassemble and replace the transport cleaning brush 704, and it can also prevent it from loosening due to vibration during operation, thus ensuring stable cleaning effect.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
