Clamp used for bearing machining

Abstract

The invention discloses a clamp used for bearing machining and relates to the technical field of bearing machining equipment. The clamp comprises a power box. The top of the control box is in slidingconnection with clamping plates. The bottom of an inner cavity of the power box is fixedly connected with a hydraulic cylinder. A first telescopic barrel penetrates through the top of the hydraulic cylinder. A control box communicates with the right side of the first telescopic barrel. The surface of the control box communicates with piston cylinders. A push rod penetrates through the end, away from the control box, of each piston cylinder. According to the clamp used for bearing machining, by arranging the four clamping plates, the outer ring of a bearing can be clamped tightly, when the outer ring of the bearing needs to be machined, top plates can be moved into the bearing by only needing to eject up a large piston through hydraulic oil, stop plugs can be moved upwards by continuously filling hydraulic oil, the hydraulic oil enters the piston cylinders, accordingly, the push rods eject the top plates out to clamp the inner surface of the bearing, the accordingly, an internal clamping mode can be set in a switching mode, a clamping device does not need to be replaced, using is convenient, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of bearing processing equipment, in particular to a clamp for bearing processing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. It is a ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fixture based on bearing processing, which solves the problem that the existing fixture usually only clamps the outer surface or inner surface of the bearing unilaterally, and needs to be replaced when processing different positions of the bearing. Different fixtures, troublesome problems to use
