Automatic polishing machine for circular glass hole

Abstract

The invention discloses an automatic polishing machine for a circular glass hole, comprising a glass processing-positioning platform, a portal frame and a pneumatic polishing device, wherein the glass processing-positioning platform comprises a rack and a lifting support frame, the lifting support frame penetrates through a bracket so as to bear a piece of glass, and is internally provided with a central positioning rod; the central positioning rod is connected with a positioning air cylinder arranged on the bracket, the bracket is also provided with a support frame lifting air cylinder which is connected with the lifting support frame and used for driving the lifting support frame to ascend and descend; the portal frame comprises an oscillating bar capable of oscillating so as to control a ring-shaped pressing plate to ascend and descend and further press the periphery of a circular hole in glass G; and the pneumatic polishing device is arranged on the portal frame in a sliding manner along the vertical direction, comprises a polishing wheel capable of autorotation and revolution, and is used for grinding and polishing a glass hole in the glass born by the lifting support frame. The automatic polishing machine is used for automatically grinding and polishing the circular hole in the plate glass so as to improve the polishing quality and the polishing efficiency of the circular glass hole and have good economic benefits.

Description

technical field [0001] The invention relates to a flat glass hole grinding device, the purpose of which is to grind and polish the inner walls of holes with different diameters drilled on a glass plate, so as to improve the smoothness of the hole surface and meet the needs of glass processing technology. Background technique [0002] The smoothness of existing flat glass is poor after drilling. Since the glass drilling is completed by combining the upper and lower drill bits, when the center of the upper and lower drill bits deviates, most of the inner surfaces of the drilled holes will have steps. Even if there are no steps, the surface of the hole will The finish of the glass is also very poor, which affects the further processing of the glass and the needs of the process. And the grinding and polishing of existing glass is to utilize hand-held small polishing machine to polish, and efficiency is low, and polishing quality is poor. [0003] In view of this, in order to s...

[0002] The finish of the existing flat glass is poor after drilling

Since the glass drilling is completed by combining the upper and lower drill bits, when the center of the upper and lower drill bits deviates, most of the inner surfaces of the drilled holes will have steps. Even if there are no steps, the surface of the hole will The finish of the glass is also very poor, which affects the further processing of the glass and the needs of the process

However, the grinding and polishing of existing glass is carried out by using a hand-held small polishing machine, which has low efficiency and poor polishing quality.
