Clamp for grinding machining of outer ring of tapered roller bearing

Abstract

The invention discloses a clamp for grinding machining of an outer ring of a tapered roller bearing. The clamp comprises a clamp body, support pillars, clamping jaws, elastic parts and a retainer ring, wherein a section of the clamp body is of a T shape; at least four support pillars are arranged at an I-shaped part of the T-shaped clamp body in an annular array form; sliding chutes are radially formed in an outer end surface of the linear part of the T-shaped clamp body; the sliding chutes are equal to the support pillars in quantity and are positioned on the same straight line; the clamping jaws are equal to the support pillars in quantity; inner ends of the clamping jaws are positioned in the sliding chutes; outer ends of the clamping jaws are hinged with the support pillars; tapers are formed at the upper ends of the clamping jaws; the elastic parts are arranged between the clamping jaws and the clamp body; and the retainer ring is in threaded connection to the I-shaped part of the T-shaped clamp body. The clamp for the grinding machining of the outer ring of the tapered roller bearing disclosed by the invention enables to the grinding machining to be stable and can adapt to outer rings with various sizes of the tapered roller bearing; and according to the clamp, the problem that the requirement of grinding machining is met by manufacturing taper sleeves with multiple sizes is solved and the machining cost is reduced.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for grinding the outer ring of a tapered roller bearing, and belongs to the technical field of workpiece clamping devices for mechanical processing. Background technique [0002] Bearings are components that fix and support shafts in mechanical equipment, and also have the function of reducing the friction coefficient during power transmission. There are many types of existing bearings, among which tapered roller bearings are more commonly used. Tapered roller bearings consist of an inner ring, rollers, a cage and an outer ring. The inner bore of the outer ring is usually tapered. At present, when the outer ring of the tapered roller bearing is ground, the tapered sleeve is used to complete it. In this way, when processing the outer rings of tapered roller bearings of different specifications, it is necessary to use matching tapered sleeves, so it is necessary to make tapered sleeves of v...

Problems solved by technology

In this way, when processing the outer rings of tapered roller bearings of different specifications, it is necessary to use matching tapered sleeves, so it is necessary to make tapered sleeves of various specifications to meet the requirements of grinding processing, which increases the processing cost; and the tapered sleeves After long-term use, the outer ring of the tapered roller bearing is easy to fly out during the grinding process, the grinding process is unstable, and it is easy to cause safety hazards
