Polishing device for small side plates of table tennis bat handle

Abstract

The invention relates to a polishing device for small side plates of a table tennis bat handle. The polishing device comprises a base, a polishing assembly, a pressing assembly and a limiting plate assembly. The pressing assembly is mounted on the base and comprises a cross beam, a press rod, a first elastic piece, a limiting rod, a first vertical rod and a baffle, wherein the cross beam is fixed to the two side faces of the base and is higher than the upper surface of the base, one end of the press rod is hinged to end of the upper surface of the cross beam, the other end of the press rod extends along the cross beam, the first elastic piece is arranged on the cross beam and is connected with the press rod, the limiting rod is arranged on the cross beam and is located in the same plane with the press rod, the first vertical rod is connected with the press rod and is located on one side of the cross beam, and the baffle is connected with the lower end of the first vertical rod and is located above a polishing abrasive belt. The limiting plate assembly is located below the cross beam. On one hand, the limiting rod is used for limiting the travel of the press rod, and the polishing unevenness caused by overlarge force for pressing the press rod is avoided; on the other hand, the small side plates are limited to or separated from the limiting plate assembly by using the up-and-down movement of the baffle, in this way, the small side plates can be continuously polished, and working efficiency is improved.

Description

technical field [0001] The invention relates to a grinding device, in particular to a grinding device for a small side plate of a handle of a table tennis racket. Background technique [0002] Commonly used table tennis rackets comprise base plate, sponge and rubber three parts, and wherein base plate is made up of racket face and handle, and the handle place of base plate is symmetrically bonded with two symmetrical small side plates. In order to ensure the quality of the table tennis racket and improve the feel of the racket user, the bonded small side panels should be properly polished, and the arc-shaped outer surface only needs to be moderately polished to prevent the user from sweating when exercising And cause the slippage of table tennis racket; And the bottom surface of small side plate is owing to will be bonded with base plate, so will be polished to smooth, otherwise causes uneven glue on the small side plate and easily comes off from base plate. [0003] At pre...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no special equipment for grinding the bottom surface of the small side plate. It is more that the operator presses the bottom surface of the small side plate on the ordinary grinding machine, which requires a large amount of pressing force of the operator. , on the other hand, due to the uneven application of the pressing pressure channel, it is difficult to control the grinding quality, and it takes a long time to polish and the efficiency is low
