Clamping width-adjustable mandrel grinder

Abstract

The invention provides a clamping width-adjustable mandrel grinder, which is capable of automatically grinding a groove in a mandrel and has higher grinding precision and processing efficiency. The clamping width-adjustable mandrel grinder comprises a machine body, a feeding box, a feeding mechanism, an upper grinding mechanism and a lower grinding mechanism, wherein a discharge outlet for the mandrel to get in or out is formed between the feeding box and the workbench; the mandrel is pushed to the upper part of an upper grinding wheel and the upper part of a lower grinding wheel through a push plate of the feeding mechanism; a transition plate connected on the push plate penetrates a clamping plate groove in the workbench; a clamping width adjusting plate is connected to the transition plate; a turnplate is connected to the clamping width adjusting plate in a turning manner; a clamping plate is fixedly arranged on the turnplate; a limiting block is arranged on the transition plate; when the turnplate turns upward to come into contact with the limiting block, the clamping plate is protruded on the upper surface of the workbench; the push surface of the push plate is parallel with the clamping surface of the clamping plate and a distance between the push surface and the clamping surface is equal to the width of the mandrel; when the turnplate turns downward, the clamping plate is lower than the upper surface of the workbench; a turnover state keeping device enables the turnplate to turn upward to come into contact with the limiting block.

Description

technical field [0001] The technology relates to a mandrel grinding machine with adjustable clamping width for grinding grooves on mandrels with oblate, flat or rectangular cross-sections. Background technique [0002] A hammer is a commonly used hitting tool, which can cause displacement or deformation by hitting an object. A hammer is usually composed of a hammer head and a hammer handle. The hammer handle is the main grasping part of the user, and its shape, size, material, structure, etc. directly affect the actual use effect of the hammer. The hammer handle is generally composed of an oblate mandrel and a soft sheath fitted on the mandrel. As the core part of the hammer handle, the mandrel is usually formed by heating and fusing glass fibers, resins, etc., adding other chemical materials, injection molding, cooling, shaping, stretching, and cutting, and then processing several grooves on its surface. The soft sheath is fitted on the groove of the mandrel to prevent th...

AI Technical Summary

Problems solved by technology

The main processing method of the mandrel groove is manual grinding, which has low work efficiency and poor grinding accuracy; and because the raw materials of the mandrel are often harmful to the human body such as glass fiber and resin, the extremely fine dust formed during manual grinding , long-term exposure will cause serious damage to human skin, respiratory tract, etc.
