Grinding machine for groove in core rod

Abstract

The invention provides a grinding machine for a groove in a core rod, which is capable of automatically grinding the groove in the core rod and has higher grinding precision and processing efficiency. The grinding machine comprises a machine body, a feed box, a feeding mechanism, an upper grinding mechanism, a lower grinding mechanism and a lateral compaction mechanism, wherein a discharge hole is formed between the feed box and a workbench, and one core rod can pass in and out through the discharge hole; a push plate of the feeding mechanism pushes the core rod into the lower part of an upper grinding wheel and the upper part of a lower grinding wheel; the lateral compaction mechanism comprises a floating lateral pressure plate and a lateral pressure backing plate connected to the workbench; when a lateral pressure spring is in a normal state, the floating lateral pressure plate horizontally pushes the push plate down and the core rod which is translational on the workbench is compressed between the floating lateral pressure plate and the lateral pressure backing plate; a lateral pressure adjusting plate can be horizontally and movably arranged on the workbench in a direction which is parallel to the axis of the core rod; the lateral pressure spring is arranged between the floating lateral pressure plate and the lateral pressure backing plate; a lateral pressure plate guide pillar is fixed on the floating lateral pressure plate; the lateral pressure plate guide pillar and the lateral pressure adjusting plate are in horizontal sliding fit; the lateral pressure spring surrounds the lateral pressure plate guide pillar.

Description

technical field [0001] The technology relates to a mandrel groove grinding machine for grinding grooves on a mandrel with oblate, flat or rectangular cross section. 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 the soft sheath from slipp...

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.
