Quick change type split expansion mechanism

Abstract

The invention discloses a quick change type split expansion mechanism which comprises a fixture body, a locating plate, a double-end bolt, a guide sleeve, a spring sleeve, an expansion sleeve, a pressing block and an adjusting nut, wherein the locating plate is connected with the fixture body; the bottom end of the double-end bolt penetrates through a mounting hole formed in the locating plate to be connected with the fixture body; the guide sleeve is mounted on the double-end bolt in a sleeving manner through matching, and falls into the mounting hole to be connected with the fixture body; an inner hole of the spring sleeve and the excircle of the guide sleeve are mounted in a sleeving manner through tapered matching; an inner hole of the expansion sleeve and the excircle of the spring sleeve are mounted in a sleeving manner through matching; the bottom surface of the expansion sleeve is connected with the top surface of the locating plate; the pressing block is mounted in the top end of the double-end bolt in a sleeving manner, and is connected with the top surface of the spring sleeve; the top surface of the pressing block locks the pressing block to the double-end bolt through the adjusting nut; and a top compression space is kept between the bottom surface of the pressing block and the top surface of the guide sleeve. According to the quick change type split expansion mechanism, the expansion strength of the expansion sleeve is adjusted through screwing the adjusting nut, and / or the expansion range is adjusted through changing expansion sleeves with different specifications according to the location requirement; and the application range is wide, the interchangeability is high, the production efficiency is can be improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a tensioning mechanism, in particular to a quick-change split tensioning mechanism, which belongs to the positioning tool of cutting processing equipment. Background technique [0002] In the manufacturing process of metal parts, tensioning mechanism is widely used as a metal processing positioning tool because of its high positioning accuracy and convenient clamping. However, the design of the traditional tensioning mechanism is relatively complicated, with strong specificity and poor applicability. Contents of the invention [0003] The main purpose of the present invention is to overcome the deficiencies in the prior art and provide a quick-change split tensioning mechanism with a new structure. The production efficiency is improved, the production cost is reduced, and the invention has the advantages of easy production, safety, reliability, and strong practicability. [0004] In order to achieve the above object, the te...
