Adjustable grinding fixture of glass column grinding device

Abstract

The invention discloses an adjustable grinding fixture of a glass column grinding device, which includes an inner fixture and a nut, the inner fixture includes a clamping part and a first fixing column, and a circle of parallel bars is arranged on the outer surface of the first fixing column. The first protrusion, the clamping part is arranged on the upper end of the first fixed column, the clamping part includes a lower cylinder connected to the first fixed column and an upper cone column connected to the lower cylinder, a section of first thread is arranged on the lower cylinder, and the lower cylinder and the two sides of the upper cone column are respectively provided with corresponding cracks. One end of the first fixed column connected to the lower cylinder is provided with a groove inward, the diameter of the groove is the same as the inner diameter of the lower cylinder, a high-pressure spring is connected to the bottom of the groove, and a support plate is connected to one end of the high-pressure spring, and the inner surfaces of the groove are respectively Correspondingly, there are two rows of marbles, the side of the support plate is provided with concave holes corresponding to the marbles, the side of the first fixing column is provided with a strip groove, and one side of the support plate is provided with a paddle, and the paddle extends along the strip groove out of the first fixed post.

Description

technical field [0001] The invention relates to a fixture, in particular to an adjustable grinding fixture 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 force and too rough to grind...

Problems solved by technology

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 Previously, a fixture was first needed to clamp the glass column for grinding, but the existing fixture had the problem of insufficient clamping force and too rough to grind glass columns of different lengths
