Grinding fixture of glass column grinding device

Abstract

The invention discloses a grinding fixture of a glass column grinding device. The grinding fixture comprises an inner fixture and a nut and is characterized in that the inner fixture comprises clamping pieces and a first fixing column; a circle of parallel first protrusions are arranged on the outer side face of the first fixing column; the clamping pieces are arranged at the upper end of the first fixing column; each clamping piece comprises a lower cylinder connected with the first fixing column and an upper conical cylinder connected with the lower cylinder; each lower cylinder is provided with a segment of first thread; and the two sides of each lower cylinder and the two sides of the corresponding upper conical cylinder are each provided with a corresponding clamping seam in a through manner. When a glass column is placed in the clamping pieces, the nut is connected to the surfaces of the clamping pieces in a screwed manner, meanwhile the nut can have pressure on the clamping pieces, the clamping seams can shrink under the pressure so that the glass column can be conveniently clamped, the glass column is kept steady in the grinding process and cannot become loose, and the grinding precision of the glass column is improved. The grinding fixture of the glass column grinding device has the beneficial effects of being simple in structure, convenient to use, good in clamping force and the like.

Description

technical field [0001] The invention relates to a jig, in particular to a grinding jig for a glass column grinding device. Background technique [0002] Glass is formed by melting silica and other chemicals together. A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling to cause it to crystallize. Glass is widely used, including buildings, daily necessities, mechanical equipment, etc. Glass plays an indispensable role in daily life and work. However, after some glass is produced, it needs to be precision ground again before it can be put into use. For example, for some cylindrical glass, the ends of one or both ends need to be ground into a smooth spherical shape. Grinding the glass column Before, a jig was first needed to clamp the glass column for grinding, but the existing jig had the problem of insufficient clamping and too rough.
