Problems solved by technology

Figure 10 What is shown is a torsion bar of an electric power steering system. The rod body is not cylindrical, but is composed of multiple concentric but unequal diameter cylinders. For this type of combination of multiple concentric but unequal diameter cylinders At present, the segmented grinding method is adopted for the slender shaft. For the combined slender shaft with high precision requirements, the traditional processing method is difficult to guarantee the required processing accuracy, and the processing efficiency is low. The profile plate is used to trim the shape of the grinding wheel and guide wheel on the grinding machine, and the above-mentioned combined slender shaft is processed by profiling one-time grinding, which needs to solve the loading and unloading problem. At present, there is no combined slender shaft loading and unloading suitable for centerless grinding machines. device

Abstract

The invention discloses a mechanical arm device of a centerless grinding machine, which comprises a supporting plate, a bracket fixed on a main machine rack, a hydraulic cylinder fixed on the lower part of the bracket, a pair of guide pillars fixed on the upper part of the bracket and a lifting seat for driving the pair of guide pillars to slide by a piston rod of the hydraulic cylinder. A pair of mechanical arms for arranging work pieces on the supporting plate is arranged on the lifting seat. The thicknesses of the lower parts of the two mechanical arms are smaller than that of the work piece. An elastic pressure plate component is arranged between the two mechanical arms on the lifting seat. The device has a simple structure; and the pair of mechanical arms supports the two ends of each work piece to realize loading and unloading, and is driven by the hydraulic cylinder, so that the loading and unloading are more stable and accurate and entire-shaft profiling can be realized. The device solves the problem that the conventional centerless grinding machine cannot machine a combined slender shaft consisting of a plurality of concentric cylinders with different diameters, and compared with the conventional device utilizing ordinary external grinding, improves the machining accuracy and reduces the rejection rate.

Description

technical field [0001] The invention relates to a centerless grinder, in particular to a centerless grinder manipulator. Background technique [0002] The centerless grinding machine adopts centerless clamping, and the workpiece is placed between the grinding wheel and the guide wheel, and is supported by the supporting plate and the guide wheel. At present, for the grinding of short cylindrical rotary workpieces such as bearing rollers, automatic loading and unloading can be realized by loading and unloading devices. The Chinese Patent No. 200820233899.1 utility model patent specification discloses an automatic loading and unloading device for a centerless grinder, which has an inclined feeding chute installed above the grinding wheel, and the outlet of the feeding chute is at the outlet of the feeding chute 1. A feeding push rod driven by the feeding power device that can move up and down is installed directly above the processing station, and a horizontally moving discha...
