Problems solved by technology

Therefore, in the above-mentioned spheronization process, the alignment relationship between the fixture and the grinding wheel has a great influence on the yield rate of the spheronization process.
[0003] In the prior art, regarding the alignment between the rounding jig and the grinding wheel of the grinding machine, the usual practice is to judge the alignment with human eyes. This method has a large error, resulting in a very low yield rate of the rounding process.

Embodiment Construction

[0011] Please refer to figure 1 As shown, the rolling jig according to the preferred embodiment 1 of the present invention includes a jig body 1 , an engaging portion 2 and a positioning pin 3 .

[0012] The jig body 1 is roughly a cuboid, which has a working surface 11 and an end surface 13 perpendicular to the working surface 11. A groove 12 is opened on the working surface 11. The groove 12 is a V-shaped groove, which ends at the end surface. 13.

[0013] The joint part 2 is a cuboid, and a positioning hole 22 is opened on the top thereof. The joint part 2 is connected to the end surface 13 of the jig body 1, and the connection method can be glue connection or bolt connection. It can be understood that the joint part 2 and the jig body 1 can also be integrally formed.

[0014] The positioning pin 3 includes a main body portion 31 and a pin portion 32 connected to one end of the main body 31. The main body portion 31 is a columnar body, which can be cylindrical or rectangu...

Abstract

A rolling tool characterizes that said tool includes a tool, a joint part and a location pin, in which, the tool has a working surface opened with a groove, the joint part is connected with one end of the tool stopping said groove and the location pin is set on the joint part.

Description

【Technical field】 [0001] The invention relates to a rounding jig, in particular to a rounding jig which is convenient for positioning in the rounding process. 【Background technique】 [0002] Circular lenses are widely used. For example, in digital camera modules of mobile phones, it is usually necessary to add a filter to make the image clearer. Since the lens barrel is mostly circular, the components in the lens barrel such as filters are also Often round. In the prior art, the manufacturing process of a circular filter is usually to cut the coated mother chip into a small square with a cutting machine, and then round it with a rounding machine. During the rounding process, a single multi-piece method is usually used. , the specific method is: before the rounding, glue a plurality of square optical filters together, then fix the columnar body of the glued optical filter on a jig, pass through the grinding wheel of a grinder. The cylindrical body of the optical filter grin...
