Abstract

The invention discloses a bearing outer-circle superfinishing machine which comprises a base. A vertical plate is arranged on the base, a polishing mechanism is further arranged on the base, and a feeding mechanism is arranged on the vertical plate. The bearing outer-circle superfinishing machine has the advantages that a bearing is located through an electromagnetic pole tip and a soft material conveying ring sleeve, an outer circle of the bearing is grinded through self-compensating oilstone, accuracy is high, supporting marks can be eliminated with a 5-8-micrometer outer-diameter allowance of the outer circle of the bearing, and the rejection rate is quite low.

Description

technical field [0001] The invention relates to a bearing processing equipment, in particular to a bearing outer ring processing equipment. Background technique [0002] The general grinding process of the outer ring of the tapered bearing is: 1. Double-end grinding 2. Fine grinding of the outer diameter 3. Rough grinding of the raceway 4. Fine grinding of the raceway (4-6μm convexity of the raceway) 5. 6. Smooth outer diameter. [0003] Since the raceway of the outer ring was processed without convexity in the past, there are many models and quantities in stock. Now on the basis of the original bearing outer ring, the raceway must have convexity, so the outer ring in stock needs to be reground to bring out the convexity. However, when grinding the crown of the raceway, such as figure 1 figure 2 , where 1 is the outer ring of the bearing, 2 is the supporting foot, and 3 is the grinding head, which needs to be clamped and fixed by the supporting foot to fix the outer rin...
