Clamping mechanism on cup body polishing equipment

Abstract

The invention discloses a clamping mechanism on cup body polishing equipment. The clamping mechanism comprises a conical disc, a rotating shaft, and an upper support base, wherein the conical surfaceof the conical disc is towards a cup body support base; the rotating shaft penetrates through the upper support base and the conical disc; the conical disc is movably connected to the upper support base; an elastic part is arranged between the conical disc and the upper support base; multiple axial chutes are formed in the lower end of the rotating shaft; a clamping member rotatably connected to the rotating shaft and the conical disc synchronously is mounted in each chute; the clamping member comprises a first clamping strip and a second clamping strip having an included angle therebetween; the first clamping strip is positioned above the conical disc, and abuts against the edge of a shaft hole of the conical disc; the second clamping strip is positioned under the conical disc, and abutsagainst the edge of the shaft hole of the conical disc; and when the conical disc is upwards displaced, the first clamping strip is pushed to rotate into the rotating shaft, so that the second clamping strip is driven to rotate outside the axial direction.

Description

technical field [0001] The invention relates to the technical field of insulation cup production equipment, in particular to a clamping mechanism on a cup body polishing equipment. Background technique [0002] Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the polishing disc installed on the polishing machine to rotate at high speed, and the polished workpiece on the polishing disc rubs the surface to be polished, so as to achieve the purpose of removing paint surface pollution, oxide layer and shallow marks. In the field of thermos cup processing, the cup body needs to enter the fine polishing process after rough polishing with abrasive belts or grinding wheels, and the fine polishing generally uses cotton wheels to polish the cup body. [0003] At present, the polishing machines on the market generally include a cup fixing device that fixes the cup body and provides rota...

AI Technical Summary

Problems solved by technology

The cup body fixing device in the prior art is generally fixed by extending the cylinder or mechanical claws into the mouth of the cup body and tightening the cup body from the inside. The clamping method of the cylinder cannot be applied to the clamping work of cups with different calibers. , the structure of the clamping method of the mechanical claw is complicated, and it is not convenient to follow the rotation of the cup after clamping. Therefore, it is necessary to improve it and propose a simple clamping mechanism with a wide range of applications
