Non-contact laser processing spring piece chuck for irregular polyhedron

Abstract

The invention provides a non-contact laser processing spring piece chuck for an irregular polyhedron. The non-contact laser processing spring piece chuck comprises a spring piece clamp, a connection shaft sleeve and a rotary fastening sleeve, wherein the spring piece clamp comprises a material clamping part, a pressure bearing part and a connection part; the material clamping part is composed of two horizontal clamping sections which are arranged oppositely; the pressure bearing part is composed of two spring pieces which are inclined outward relative to the two clamping sections; one end of each spring piece is connected with one clamping section and the other end of each spring piece is connected with one end of the connection part; the connection part is fixed to the left end of the connection shaft sleeve; an outer wall of the connection shaft sleeve is in thread connection with an inner hole of the rotary fastening sleeve, so that the material clamping part can completely stretchout of a left end opening of the inner hole of the rotary fastening sleeve; the pressure bearing part transversely penetrates through the left end opening of the inner hole of the rotary fastening sleeve; when the connection shaft sleeve is fixed, the rotary fastening sleeve is rotated leftward; the two spring pieces are extruded through the left end opening of the inner hole of the rotary fastening sleeve so that an irregular polyhedron material is tightly clamped through the two clamping sections. The non-contact laser processing spring piece chuck for the irregular polyhedron, provided by the invention, has the beneficial effects that a clamping process is simple, direct and rapid, and the clamping efficiency and clamping reliability of the irregular polyhedron material are improved.

Description

technical field [0001] 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 [0002] 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 ...

Problems solved by technology

[0003] Please refer to Image 6 , the traditional clamping method is to use chemical reagents to stick and fix the irregular polyhedron. The irregular polyhedron material 1 is some completely irregular polyhedral mineral crystal materials with a particle size ranging from 3mm to 10mm. There is no doubt about its particularity in shape 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 glue to bond and fix the irregular polyhedron 1 with a metal sticky rod 102. In order 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 cannot withstand too high a temperature, and the high temperature generated during laser processing will destroy the bonding , so that the material is detached from the fixation. As for the high-temperature-resistant inorganic 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, and no other irregular polyhedral material mounting has been found through investigations and researches on laser processing and EDM. clamp tool
