Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing inner ring retaining edge grinding device. Background Technology

[0002] Grinding is a cutting process that uses grinding heads to remove excess metal from a workpiece. Grinding is one of the most commonly used processing methods in mechanical manufacturing. It can process high-hardness and ultra-hard materials that are difficult to process by other cutting methods, such as hardened steel, high-strength alloys, cemented carbide and ceramics. In addition, grinding is different from general cutting processes. Besides cutting, it also has the functions of scribing and polishing.

[0003] Grinding is a key step in the bearing manufacturing process. It involves not only machining the outer and inner ring surfaces of the bearing, but also machining the inner ring flange. Grinding the inner ring flange is crucial to ensuring the surface accuracy and smoothness of the bearing inner ring flange.

[0004] During the grinding process, the grinding surface temperature is high, and excessively high temperatures can affect the quality of the workpiece, thus requiring cooling. The most common method is water cooling, which serves both a cooling and dust suppression function. However, because the cooling water contains metallic impurities, it is difficult to recycle, hindering resource conservation. Therefore, this application proposes a bearing inner ring retaining edge grinding device that enables the grinding of the bearing inner ring retaining edge while simultaneously recycling the cooling water, thus contributing to resource conservation.

[0025] A grinding motor 3 is fixedly installed on one side of the upper housing 1. The grinding motor 3 is connected to the grinding head 31, and the grinding head 31 is engaged with the retaining edge of the inner ring 7 of the bearing.

[0026] A first drain hole 112 is provided at the bottom of the upper box 1, and the upper box 1 is connected to the lower box 12 through the first drain hole 112. A support partition 121 is provided in the lower box 12, and a water passage hole 122 is provided on the support partition 121.

[0029] The principle of this utility model is as follows:

[0030] This utility model is used for grinding and polishing the inner ring flange of a bearing. In use, the inner ring 7 of the bearing is fixedly placed in the fixing plate 44. During the process, the arc-shaped clamping groove 446 in the fixing plate 44 facilitates the placement and fixing of the inner ring 7 of bearings of different specifications.

[0031] During the grinding process, the drive motor 2 drives the fixed disk 44 to rotate stably, and the grinding motor 3 drives the grinding head 31 to grind the inner ring retaining edge of the bearing, thereby realizing the grinding process of the inner ring retaining edge of the bearing. During the grinding process, in order to avoid the grinding surface from overheating and affecting the performance of the inner ring 7 of the bearing, water cooling is used to cool it down. On the other hand, it also avoids the dust from grinding from polluting the working environment.

[0032] Cooling water flows down from the spray pipe 52 to cool the grinding surface, and then flows through the periphery of the fixed plate 44 and the bottom of the fixed groove 442 to the bottom of the upper box 1. The first baffle 111 on the outside of the upper box 1 prevents water from overflowing. The water at the bottom of the upper box 1 flows down from the second drain hole 443 into the lower box 12. In this utility model, the diameter of the first drain hole 112 and the second drain hole 443 is 5-10mm to ensure stable water flow.

[0033] When the water flows into the lower tank 12, it is filtered by the filter cloth 6 on the support partition 121 and then flows into the water collection tank 5 below. After that, it is drawn by the circulation pump 51 and reused. In this embodiment, since grinding is an intermittent operation and the circulating water volume is large, although the water temperature will rise to some extent during the circulation process, it will not affect the stable use. In actual applications, if the working intensity is high and the water temperature rises rapidly, certain auxiliary temperature control measures can be adopted, such as replacing the circulation pump with a chiller. This is easy for those skilled in the art to understand and will not be elaborated further.

[0034] In this invention, since the dust particles generated by grinding are small, the pore size of the filter cloth 6 is required to be high. In actual production, an 8000-mesh filter cloth 6 is used to ensure stable production and will not affect the pump body. The filter cloth 6 can be cleaned periodically.
