Problems solved by technology

[0002] Optoelectronic devices need to grind and polish the coupling end face before coupling, but the lengths of different optoelectronic device chips are different, so different sizes of grinding and polishing jigs are required during the grinding and polishing process, which causes difficulties when switching chip production status. It is necessary to use chip grinding fixtures of different lengths, which increases production costs and reduces production efficiency

Embodiment 1

[0048] Such as Figure 1~2, in this embodiment, the fixture capable of grinding chips with multiple lengths includes: a mechanical base 1 and a pressing plate. Preferably, the mechanical base 1 includes: plate mounting holes I103, plate mounting holes II104, plate mounting holes III106, plate mounting holes IV108, bottom surface 110, first column 111, and second column 112; wherein, the first column 111 and the second column Two columns 112 are arranged on the bottom surface 110 , and the first column 111 and the second column 112 are spaced apart to form a grinding chamber 113 . Further, the surface of the first column 111 close to the second column 112 includes: a first installation surface 1111, a second installation surface 1112 and a third installation surface 1113; wherein, the first installation surface 1111 and the third installation surface The surfaces 1113 are on the same plane, and the plane where the second installation surface 1112 is located is lower than the p...

example 1

[0053] Such as image 3 , the pressure plate I201 is provided with a pressure plate hole I2011 and a pressure plate hole II2012. Wherein, the pressure plate hole I 2011 and the pressure plate hole II 2012 are paired and arranged symmetrically with respect to the center line of the pressure plate I 201 .

[0054] When grinding a chip to be processed with a length ranging from 55 mm to 60 mm, press plate hole I 2011 is docked with press plate mounting hole II 104 , and press plate hole II 2012 is docked with press plate mounting hole IV 108 . That is to say, when no gasket is placed in the grinding chamber 113, the length of the chip to be ground is the longest, and the press plate I 201 with the highest height is required for assembly to realize the connection between the press plate and the mechanical base and fix the chip to be processed.

example 2

[0056] Such as Figure 4 , the fixture capable of grinding chips with multiple lengths may further include: gasket I 301 . Wherein, the spacer I301 is provided with a spacer hole I3011, and the spacer hole I3011 is in pairs and arranged symmetrically with respect to the center line of the spacer I301.

[0057] Further, such as Figure 5 , the pressure plate II 202 is provided with a pressure plate hole III 2021 and a pressure plate hole IV 2022; both the pressure plate hole III 2021 and the pressure plate hole IV 2022 are paired and arranged symmetrically about the center line of the pressure plate II 202.

[0058] When grinding chips to be processed with a length ranging from 50 mm to 55 mm, press plate hole III 2021 is docked with press plate installation hole II 104, press plate hole IV 2022 is docked with press plate installation hole IV 108, and gasket hole I3011 is docked with gasket placement installation hole V109. That is to say, when a gasket I301 is placed in the ...

Abstract

The invention discloses a grinding fixture suitable for chips of multiple lengths. The grinding fixture suitable for chips of multiple lengths comprises a mechanical base and a press plate. The mechanical base comprises four pairs of press plate installation holes, a bottom face, a first stand column and a second stand column. The first stand column and the second stand column are arranged on thebottom face in a spaced manner, so that a grinding cavity is formed. The surface of the side, close to the second stand column, of the first stand column is divided into a first installation face, a second installation face and a third installation face, wherein the first installation face and the third installation face are symmetrical and are each provided with three concave faces and two convexfaces. The four pairs of press plate installation holes are symmetrically arranged on the concave faces and the convex faces of the first installation face and the third installation face. During machining, a to-be-machined chip is arranged in the grinding cavity and is tightly pressed and fixed through the press plate and the surface of the side, close to the second stand column, of the first stand column. By changing the grinding height of the grinding cavity, the chips of different lengths can be ground, the problem that different types of chips need different grinding chips is solved, andthe grinding fixture suitable for chips of multiple lengths improves production operation efficiency and lowers production cost.

Description

technical field [0001] The invention belongs to the technical field of chip grinding, and in particular relates to a fixture capable of grinding chips with multiple lengths. Background technique [0002] Optoelectronic devices need to grind and polish the coupling end face before coupling, but the lengths of different optoelectronic device chips are different, so different sizes of grinding and polishing jigs are required during the grinding and polishing process, which causes difficulties when switching chip production status. It is necessary to use chip grinding fixtures of different lengths, which increases production costs and reduces production efficiency. The requirements for high precision, short production cycle and low cost of aerospace products are facing unprecedented challenges and opportunities.
