Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a positioning fixture for glass processing.

[0004] The purpose of this utility model is achieved through the following technical solution: a positioning fixture for glass processing, including a fixture body, the fixture body including a base plate and a fixing seat fixed to the top center of the base plate, two positioning columns symmetrically fixed to the top front side of the fixing seat, a vacuum adsorption groove is opened in the top center of the fixing seat, and a first processing groove, a second processing groove and a third processing groove are symmetrically opened from front to back on the left and right sides of the top of the fixing seat corresponding to the vacuum adsorption groove, the vacuum adsorption groove is in the shape of a grid, and an air extraction hole penetrating the upper and lower surfaces of the fixture body is opened at the bottom of the vacuum adsorption groove.

[0005] Furthermore, the first and second processing grooves are both circular, while the third processing groove is shaped like a football field.

[0006] Furthermore, a fourth processing groove is provided on the right side of the third processing groove on the left side of the top of the fixed base.

[0007] Furthermore, the cross-section of the fixing base is a rounded rectangular structure.

[0008] The beneficial effects of this utility model are as follows: The positioning fixture for glass processing of this utility model improves the problems of inaccurate positioning in secondary processing and complicated product handling by symmetrically fixing two positioning columns on the top front side of the fixed base, thereby improving processing efficiency and reducing costs.

Detailed Implementation

[0011] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0012] See Figure 1 A positioning fixture for glass processing includes a fixture body 1. The fixture body 1 includes a base plate 11 and a fixing seat 12 fixed to the top center of the base plate 11. Two positioning posts 13 are symmetrically fixed to the front side of the top of the fixing seat 12. A vacuum adsorption groove 14 is opened in the middle of the top of the fixing seat 12. A first processing groove 15, a second processing groove 16 and a third processing groove 17 are symmetrically opened from front to back on the left and right sides of the top of the fixing seat 12 corresponding to the vacuum adsorption groove 14. The vacuum adsorption groove 14 is in the shape of a grid. An air extraction hole 18 penetrating the upper and lower surfaces of the fixture body 1 is opened at the bottom of the vacuum adsorption groove 14.

[0013] The positioning fixture for glass processing of this utility model improves the problems of inaccurate positioning in secondary processing and complicated product handling by symmetrically fixing two positioning columns 13 on the top front side of the fixed base 12, thereby increasing processing efficiency and reducing costs.

[0014] In this embodiment, the first processing groove 15 and the second processing groove 16 are both circular, and the third processing groove 17 is shaped like a football field.

[0015] In this embodiment, a fourth processing groove 19 is provided on the right side of the third processing groove 17 on the left side of the top of the fixed base 12.

[0016] In this embodiment, the cross-section of the fixing base 12 is a rounded rectangular structure.

[0017] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
