Outer circle grinding bed

Abstract

The invention provides an outer circle grinding bed, and belongs to the technical field of machinery. The outer circle grinding bed solves the problem of how to ensure the processing quality uniformity of workpieces in two stations on the premise of improving the processing efficiency of the grinding bed. A left jacking pin of a left installing and clamping seat and a right jacking pin of a rightinstalling and clamping seat of the grinding bed have the coincident axial lines; an integrated seat is arranged between the left installing and clamping seat and the right installing and clamping seat; an installing through hole is formed in the integrated seat; the center line of the installing through hole is coincident with the axial lines of the left jacking pin and the right jacking pin; oneend of the installing through hole is provided with a first integrated jacking pin which corresponds to the right jacking pin and has the axial line coincident with the center line of the installingthrough hole; the other end of the installing through hole is provided with a second integrated jacking pin which corresponds to the left jacking pin and has the axial line coincident with the centerline of the installing through hole. The grinding bed uses the double-station design; the work efficiency is high; through the integrated design, the jacking pins in one station and the other stationare enabled to have good coaxial degree, so that the processing quality uniformity of the workpieces on the two stations can be ensured; in addition, the occupied space and the manufacturing cost aregreatly reduced.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a cylindrical grinding machine. Background technique [0002] The cylindrical grinder is mainly used for grinding the outer surface of the cylindrical, conical or other shapes and the end surface of the shaft shoulder. Among all the grinding machines, the cylindrical grinding machine is the most widely used type of machine tool. It is generally composed of a cast iron bed, a worktable, a headstock that supports and drives the workpiece to rotate, a tailstock, and a grinding head. (Grinding wheel) grinding head frame, lateral feed mechanism to control the size of the grinding workpiece, electrical appliances and hydraulic devices to control the movement of machine tool moving parts and other main components. Cylindrical grinders can generally be divided into ordinary cylindrical grinders, universal cylindrical grinders, wide grinding wheel cylindrical grinders, end face cylindric...

AI Technical Summary

Problems solved by technology

[0005] However, as can be seen from the above-mentioned disclosed grinding machine, if the existing grinding machine adopts a double-station design, two sets of fixtures must be used to clamp the two workpieces. Often due to errors in the design and installation of the two sets of fixtures, the clamping and positioning The axis of the thimble used cannot be completely coaxial; and the workpiece itself is clamped on the two sets of fixtures, and there are clamping and calibration errors, which leads to poor coaxiality of the two workpieces during actual processing, resulting in two stations The processing quality of a batch of processed workpieces is inconsistent, which affects the subsequent processing of workpieces and the formulation of quality inspection standards
