Groove Position Adjustable Mandrel Groove Grinding Equipment

Abstract

The invention provides a mandril groove grinding device capable of adjusting a groove position; the mandril groove grinding device is capable of automatically grinding a groove in a mandril, and higher in grinding accuracy and machining efficiency. The mandril groove grinding device comprises a machine body, a feeding tank, a feeding mechanism, an upper grinding mechanism, a lower grinding mechanism and a side pressing mechanism, wherein a material outlet which enables the mandril to get in and out is formed between the feeding tank and a working platform; a pushing plate of the feeding mechanism is used for pushing the mandril to the lower part of an upper grinding wheel and the upper part of a lower grinding wheel; an upper tank body is arranged on the machine body through a guide post and guide sleeve structure in a vertical sliding way; the machine body is rotationally provided with an upper lifting screw rod; an upper lifting sliding block which is matched with the upper lifting screw rod is connected with the upper tank body; an upper guide rail which is parallel to the axis of the mandril and an upper translation screw rod are arranged on the upper tank body; the upper grinding mechanism is arranged on the upper guide rail in a sliding way; an upper translation sliding block which is matched with the upper translation screw rod is connected with the upper grinding mechanism.

Description

technical field [0001] The technology relates to a mandrel groove grinding device with adjustable groove position 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 pre...

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.
