Fast fixing tool for machining bearing inner ring

Abstract

The invention discloses a fast fixing tool for machining a bearing inner ring. The fast fixing tool comprises a working table. A lead screw is installed on the working table. A hand wheel is installedon the portion, located at the lower end of the lead screw, of the bottom of the working table. A medium swivel nut is installed on the portion, located on the lead screw, of the top of the working table. Multiple oblique supporting rods are arranged on the bottom of the medium swivel nut in the peripheral direction. The lower ends of the oblique supporting rods are fixed to the working table. Multiple telescoping devices are arranged on the outer side of the medium swivel nut in the peripheral direction. Clamping plates are fixedly installed at the outer ends of the telescoping devices. An upper swivel nut body and a lower swivel nut body are symmetrically installed on the portions, located on the lead screw, of the upper side and the lower side of the medium swivel nut. Multiple upper supporting rods are hinged to the outer side of the upper swivel nut body. The other ends of the upper supporting rods are hinged to the upper portions of the inner sides of the clamping plates correspondingly. Multiple lower supporting rods are hinged to the outer side of the lower swivel nut body. The other ends of the lower supporting rods are hinged to the lower portions of the inner sides of the clamping plates correspondingly. The fast fixing tool is good in bearing fixing effect, convenient to operate, good in firmness and stability and beneficial for application and popularization.

Description

technical field [0001] The invention relates to the technical field of bearing inner ring fixing equipment, in particular to a fast fixing tool for bearing inner ring processing. Background technique [0002] Bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cages. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. When processing the inner ring of the bearing, the burrs on the inner ring need to be removed separately, but the general device for fixing the inner ring of the bearing is cumbersome to operate during use, and the inner ring of the bearing is easy to be removed from the The fixing device falls off, which will affect the efficiency of machining the inner ring of the bearing. [0003] Chinese patent (authorized announcement number: CN 207387419 U) discloses a bearing inner ring processing and fixing device, including an upper fixing part and a co...
