AI Technical Summary

Technical Problem

Existing grinding machines lack effective protective measures during workpiece grinding, which can easily cause the workpiece to be blown away when the grinding wheel feeds too much in a single cycle, posing a safety hazard.

Method used

It adopts a three-axis linkage design (X/Y/Z axis ball screw + stepper motor drive), combined with a protective device consisting of a semi-enclosed space formed by side plates, cross plates and stiffeners, to ensure precise workpiece positioning and three-dimensional fine feeding of the grinding wheel, and absorb kinetic energy when the workpiece accidentally falls out of the vise, reducing the risk of splashing.

Benefits of technology

It achieves precise workpiece positioning and uniform grinding, reduces the risk of workpiece splashing, and improves operational safety.

Abstract

This utility model discloses a high-precision flat surface grinder for machining aluminum rulers, including a frame; a horizontal feeding device is arranged on the top of the frame along the front-to-back direction, a grinding support is vertically arranged on the rear side of the top of the frame, a Y-axis feed device is arranged on the top of the grinding support, a Z-axis feed device is arranged at the front end of the Y-axis feed device, and a grinding wheel is installed on the Z-axis feed device; a protective device is also arranged at the rear of the horizontal feeding device; the protective device includes two protective side plates, which are located on the left and right sides of the horizontal feeding device respectively, and a protective cross plate is fixedly connected between the top front ends of the two protective side plates, with space left below the protective cross plate for the worktable to pass through; the protective device of this utility model forms a semi-enclosed space by the side plates, cross plate and stiffening plate, so that when the workpiece accidentally falls out of the vise, the impact protective structure can absorb the kinetic energy, greatly reducing the risk of workpiece splashing and ensuring the safety of the operator.
