Core rod grinding device

Abstract

The invention provides a core rod grinding device which is capable of automatically grinding a groove in a core rod and is higher in grinding accuracy and processing efficiency. The core rod grinding device comprises a machine body, a feeding box, a feeding mechanism, an upper grinding mechanism, a lower grinding mechanism and an upper 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 upper pressing mechanism is provided with an upper pressing plate parallel to the upper surface of the workbench; when an upper pressing spring is in a normal state, the upper pressing plate presses the core rod between the upper pressing plate and the workbench; an upper pressing adjustment plate is arranged on the machine body in an up-down liftable way; the upper pressing plate is connected to the upper pressing adjustment plate, and the upper pressing spring is arranged between the upper pressing plate and the upper pressing adjustment plate; an upper pressing plate guide column is fixedly arranged at the upper part of the upper pressing plate and is matched with the upper pressing adjustment plate in an up-down sliding way; the upper pressing spring encircles the upper pressing plate guide column.

Description

technical field [0001] The technology relates to a mandrel grinding device 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 slipping. 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.
