Fully automatic hydraulic cylinder cylinder centerless grinding machine

Abstract

The invention discloses a centerless grinding machine for the outer circle of a fully automatic hydraulic cylinder, comprising: a bed, a grinding wheel, a guide wheel, a supporting plate, a positioning guide plate, an automatic feeding device and an automatic discharging device, an automatic feeding device and an automatic lowering device. The feeding device makes the loading and unloading of the cylinder easy and convenient, reducing the labor intensity of the workers; the positioning mechanism composed of the supporting plate and the guide wheel makes the clamping of the cylinder easier and reduces the clamping time; and The positioning mechanism composed of the supporting plate and the guide wheel is better than the top and center frame mechanism of the ordinary cylindrical grinder. The supporting rigidity can be larger, and it is beneficial to the processing of the longer cylinder, and it is easy to realize high-speed grinding and powerful grinding; it can Continuous processing, no need to retract the tool, overcomes the shortcomings of low productivity of traditional processing methods.

Description

technical field [0001] The invention relates to a processing device for the outer diameter of a cylinder barrel of a hydraulic cylinder. Background technique [0002] The outer diameter of the cylinder barrel of the hydraulic cylinder needs to be ground to make its surface roughness meet the requirements of use. Traditional processing methods such as figure 1 As shown, first put the two ends of the cylinder 11 into the mandrel 12, and then hoist it on the cylindrical grinder, use the thimble 13 at both ends to withstand the center hole on the mandrel 12, and fix one end with a chicken heart clip, Then start processing. There are following disadvantages in this cylindrical grinder: [0003] 1. The process of clamping the workpiece is cumbersome and time-consuming; [0004] 2. After processing a cylinder, the tool needs to be retracted, which is difficult to process continuously and the production efficiency is low; [0005] 3. The cylinder is supported at both ends, the s...

AI Technical Summary

Problems solved by technology

[0003] 1. The process of clamping the workpiece is cumbersome and time-consuming;

[0004] 2. After processing a cylinder, the tool needs to be retracted, which is difficult to process continuously and the production efficiency is low;

[0005] 3. The cylinder is supported at both ends, the support rigidity is low, it is difficult to process a long cylinder, and the scope of application is small; and due to the low support rigidity, in order to avoid deformation of the cylinder, generally a small single feed is adopted, which is difficult to process at high speed grinding and power grinding;

[0006] 4. It is not easy to automate loading and unloading, and the labor intensity of workers is high
