Core rod groove grinding equipment

Abstract

The invention provides core rod groove grinding equipment which is capable of automatically grinding a groove in a core rod and is higher in grinding accuracy and processing efficiency. The core rod groove grinding equipment comprises a machine body, a feeding box, a feeding mechanism, an upper grinding mechanism, a lower grinding mechanism and a lateral pressing mechanism, wherein a discharging opening capable of allowing the entering and exiting of the core rod is formed between the feeding box and a workbench; a pushing plate of the feeding mechanism pushes the core rod into the lower part of an upper abrasive wheel and the upper part of a lower abrasive wheel; the lateral pressing mechanism comprises a floating lateral pressing plate and a lateral pressing backing plate connected to the workbench; a lateral pressing spring is arranged between the floating lateral pressing plate and the workbench; when the lateral pressing spring is in a normal state, the floating lateral pressing plate presses the core rod, which is horizontally pushed down by the pushing plate and horizontally moves on the workbench, between the floating lateral pressing plate and the lateral pressing backing plate; the lateral pressing backing plate is arranged on the workbench in a direction parallel to the axis of the core rod in a left-right movable way according to the structure that a sliding groove parallel to the axis of the core rod is formed in the lateral pressing backing plate and a butterfly bolt passes through the sliding groove and the workbench and is matched with a nut.

Description

technical field [0001] The technology relates to a mandrel groove grinding equipment 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 sli...

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.
