Grinding machine tool for machining outer arc surfaces of shaft parts

Abstract

The invention discloses a grinding machine tool for machining the outer arc surfaces of shaft parts. The grinding machine tool comprises a support, wherein a worm is arranged at one side of the support through bearing seats arranged at two sides; a rotating shaft is vertically arranged at the other side of the support; the upper end part of the rotating shaft is connected with a horizontally arranged fan-shaped swinging block; the edge of the rear end of the fan-shaped swinging block is provided with a worm gear which is matched with the worm to form an integral worm gear; a hollow base is arranged at the front end part of the fan-shaped swinging block; the front end of the base is equipped with a sliding sleeve which can slide in the hollow base; the front end of the sliding sleeve stretches out of the base and is fixedly connected with a diamond; the rear end part of the sliding sleeve is connected with a differential adjusting rod; one end of the worm externally stretches to the bearing seats and is connected with a handle enabling the worm to rotate; the worm is arranged on the bearing seats through bearings arranged at two ends; the rotating shaft is supported on a support seat through an upper and a lower bearing; the fan-shaped swinging block is fixedly connected with the rotating shaft through a shaft pin.

Description

Technical field [0001] The invention relates to a grinding machine tool for processing the outer arc surface of shaft parts, which belongs to the technical field of shaft parts manufacturing. Background technique [0002] Parts to be processed such as figure 1 As shown, the arc surface on the shaft adopts the existing processing technology, which cannot guarantee the processing accuracy of the parts. The processing technology generally adopts hot pre-processing and sanding after hot. The positioning tolerance and dimensional tolerance cannot be guaranteed; The main shortcomings of the processing method are summarized as follows: First, the parts are processed in place before heat treatment, and the deformation of heat treatment directly affects the accuracy; second, the surface of the parts is sanded after heating, and the dimensional accuracy cannot be guaranteed; third, the production efficiency is low and it is not suitable for mass production. Summary of the invention [0...
