Description

An irregular polyhedron non-contact laser processing spring chuck

technical field

The invention relates to the field of non-contact and non-contact stress special processing such as laser processing and electric discharge processing, and in particular to an irregular polyhedron non-contact laser processing spring clip.

Background technique

With the continuous development and updating of processing technology, some emerging non-contact processing methods have emerged, such as: laser processing and other processing methods in which the "tool" does not come into contact with the target to be processed have emerged one after another and have rapidly become popular. The wide application of non-contact processing not only reduces the clamping force requirements in the processing process, but also expands the range of material processing. It is an important processing method for some materials with high hardness and wear resistance. In the processing of irregular polyhedral materials It is necessary to perform point contact, line contact or surface contact clamping on the target to be processed according to the processing position.

Please refer to Figure 6. The traditional clamping method is to use chemical reagents to stick and fix the irregular polyhedron. The irregular polyhedral material 1 is some completely irregular polyhedral mineral crystal materials with a particle size ranging from 3mm to 10mm. Its special shape Undoubtedly, it increases the difficulty of positioning and clamping it. The traditional way of fixing and clamping it is to use sealant 101 or inorganic high-temperature-resistant adhesive to bond, so that the irregular polyhedron 1 and a metal sticky rod 102 Bonding and fixing, so as to achieve the purpose of positioning and fixing the irregular material 1, this bonding method is time-consuming and inconvenient to remove the material, and the sealant 101 can not withstand too high temperature, the high temperature generated in laser processing It will destroy the bonding and make the material detached from the fixation. As for the inorganic adhesive high temperature resistant adhesive, although it can withstand higher temperatures, it takes several hours to solidify, which increases the clamping cycle. Therefore, the use of chemical reagents to stick and fix not only needs to wait for a long time for the adhesive to solidify, but also needs to consider the impact of high temperature that may be generated during processing on the clamping stability. When removing the target, it needs to be cleaned with strong acid and alkali chemical reagents. It is very inconvenient to use, and it cannot meet the clamping requirements of non-contact processing that does not require high holding force in laser processing and other processing processes. Moreover, no other irregular polyhedron material mountings have been found through investigations and researches on laser processing and EDM. clip tool.
