Inclined wedge type grinding head feeding device

Abstract

The invention discloses an inclined wedge type grinding head feeding device. The inclined wedge type grinding head feeding device comprises an engine base, a guide column, a shell, a second oil cylinder, a roller wheel, a feeding slope rod, a first oil cylinder and a sensing component, wherein the guide column is fixedly connected with the engine base; the shell is in sliding fit with the guide column and is used for arranging a grinding head; the second oil cylinder is fixedly connected with the engine base and is used for pulling the shell towards the engine base; the roller wheel is arranged on the guide column; the feeding slope rod is arranged in the shell in a sliding mode; the first oil cylinder is arranged on the shell and is used for pulling the feeding slope rod; the sensing component is used for sensing the limit position of the feeding slope rod; and a control signal of the first cylinder is from the sensing component. The feeding device can feed slowly, reduces the feeding speed in multiples, can automatically feed and retract, and can feed repeatedly for many times without fault.

Description

technical field [0001] The invention relates to a feeding device, in particular to a wedge type grinding head feeding device. Background technique [0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machine etc. [0003] Grinding machines and grinding wheel motors used in standard mechanical processing operate according to traditional starting circuits. After the motor is started, it runs at the rated speed. Due to the fluctuation of the grid voltage, the friction load of the grinding wheel workpiece grinding machine changes continuously, which will affect the speed error of the motor grinding machine. The standard grinding wheel motor ...

AI Technical Summary

Problems solved by technology

[0005] At present, the feeding mechanism of the grinding machine usually uses a servo motor and a ball screw pair to directly drive the grinding wheel frame of the grinding machine, so the feeding accuracy of the traditional feeding mechanism is limited; and some grinding machines are fed manually. This manual feeding method not only requires Skilled technology, high labor intensity, and a little improper control leads to excessive feed, which affects machining accuracy
