Description

Technical Field

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

[0002] Gears are made of circular teeth with an equal number of teeth. Power or rotational speed is transmitted through the meshing between gears. There are various meshing methods for gears, including planar gears, bevel gears, and worm gears. Planar gears have smooth meshing and high transmission efficiency, and are widely used in various mechanical equipment.

[0003] According to the utility model patent application CN221583005U, a deburring grinding device for gears is disclosed, which includes a housing with a processing position. In the processing position, a gear body and a rotating mechanism are installed sequentially from top to bottom. A movable grinding mechanism is installed on one side of the gear body. The grinding mechanism has two grinding parts divided into two upper and lower parts and a moving mechanism for driving the two grinding parts closer to the gear body.

[0004] Although this equipment, through the addition of a moving mechanism and grinding components, can bring two grinding components closer to the gear body and position them on the top and bottom sides of the gear body respectively, allowing for simultaneous double-sided grinding and deburring of the gear body as it rotates, this equipment can only grind the top and bottom surfaces of the gear and cannot grind the grooves on the gear, resulting in a reduction in gear production quality. Therefore, we provide a device for grinding gear surfaces to solve these problems. Utility Model Content

The protective seat 4 can protect the hydraulic telescopic rod 207 and prevent it from being disturbed by external factors during use.

[0025] See Figure 1 , Figure 3 and Figure 5 A bearing 212 is fixedly connected to the inner wall of the base plate 1, and a fixing column 211 is fixedly connected to the inner ring of the bearing 212. A fixing frame 208 is fixedly connected to the bottom surface of the base plate 1. A reinforcing plate 5 is fixedly connected to the outer surface of the telescopic end of the hydraulic telescopic rod 207. The bottom surface of the reinforcing plate 5 is fixedly connected to the upper surface of the sliding plate 203. The reinforcing plate 5 can reinforce the hydraulic telescopic rod 207 and the sliding plate 203, thereby enhancing the stability of the device.

[0026] See Figure 2 , Figure 3 and Figure 5A drive motor 213 is fixedly connected to the right side of the fixed frame 208. A sliding groove 205 is provided on the upper surface of the base plate 1. A grinding block 202 is fixedly connected to the upper surface of the base plate 1. Four fixing bolts 6 are threadedly connected to the inner wall of the reinforcing plate 5. The outer surface of each set of fixing bolts 6 is threadedly connected to the inner wall of the sliding plate 203. The fixing bolts 6 can reinforce the reinforcing plate 5 and the sliding plate 203 to prevent them from swaying or shaking during operation.

[0027] See Figure 2 , Figure 5 and Figure 6 A gear body 204 is provided above the fixed column 211. A threaded rod 206 is threadedly connected to the inner wall of the fixed column 211. A limit washer 210 is fixedly connected to the outer surface of the threaded rod 206. Four support feet 3 are fixedly connected to the bottom surface of the base plate 1. Two fixing rings 8 are fixedly connected to the outer surface of each set of support feet 3. The top of each set of fixing rings 8 is fixedly connected to the bottom surface of the base plate 1. The support feet 3 can provide stable support for the whole device. The fixing rings 8 can reinforce the support feet 3 and the base plate 1 to prevent them from shaking or shifting during use.

[0028] See Figure 2 , Figure 3 , Figure 5 and Figure 6 The bottom end of the limiting shim 210 contacts the top end of the gear body 204.

The protective box 7 can protect the drive motor 213 and prevent it from being damaged by external forces during operation.

[0029] Working principle: In use, the gear body 204 is first placed on the fixed post 211. Then, by twisting the threaded rod 206, the limiting washer 210 is driven to descend, thereby fixing and limiting the position of the gear body 204. When it is necessary to grind the groove surface of the gear body 204, the extension end of the hydraulic telescopic rod 207 is extended and retracted, driving the sliding plate (203) to rise and fall, which in turn drives the grinding disc 209 to rise and fall. Furthermore, by rotating the output end of the drive motor 213, the fixed post 210 is driven to descend. 1. Rotation drives the gear body 204 to rotate, thereby polishing the groove surface of the gear body 204. When the groove surface is polished, the upper and lower surfaces of the gear body 204 need to be polished. The telescopic end of the hydraulic telescopic rod 207 is retracted, driving the polishing disc 209 to move upward. Then, the output end of the drive motor 213 continues to rotate, driving the gear body 204 to rotate continuously. This allows the polishing block 202 to polish the upper and lower surfaces of the gear body 204, effectively avoiding the problem of not being able to polish the groove of the gear, which would lead to a decrease in gear production quality.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
