Scroll and clamping device of scroll retracting mechanism

Abstract

The invention relates to a scroll, which comprises a rotation shaft. Wherein, the positioning ends at two sides of rotation shaft are both mounted with a positioning projection; the bottom of positioning projection is fixed on the positioning end of scroll; the positioning projection is a ball table; the clamper of scroll receiving-releasing device comprises two matched clamp elements; each clamp element comprises a fixing axle and a clamp part matched with the scroll; the clamp part is at the front end of fixing axle; the fixing axles of two clamp element via bearing sheathes are fixed on two rotation shafts of frame of scroll receiving-releasing device; and the invention also comprises a reciprocating motion driving device fixed at the outer side of one rotation shaft; the back end of one fixing axle is rotationally connected to the output of reciprocating motion driving device, around the central line of fixing axle; said clamp part comprises a clamp disk and a positioning base, while the clamp disk is at the front end of fixing axle, and the front end of clamp disk has a clamp hole matched with the positioning projection, and the positioning base is at the lower side of front end of clamp disk.

Description

technical field [0001] The invention relates to a reel retractable mechanism, more specifically to a reel and a clamping device for the reel retractable mechanism of the reel. Background technique [0002] The existing reel retractable mechanism adopts better clamping devices and adopts foreign safety chucks, such as figure 1 , 2 shown. The cross-section of the positioning groove on the safety chuck is rectangular, and the cross-section of the positioning end of the reel is also rectangular, but smaller than the cross-section of the positioning groove. Therefore, during the working process, when the reel rotates, it will constantly shake, which affects the service life of each component, and has a bad influence on the winding of the product, resulting in the deterioration of the quality of the product. However, since the two cross-sections are rectangular, the user must simultaneously align the two positioning ends of the reel with the corresponding positioning grooves to...

Problems solved by technology

Therefore, during the working process, when the reel rotates, it will continue to shake, which will affect the service life of each component, and have a negative impact on the winding of the product, resulting in the deterioration of the quality of the product.

However, since the two cross-sections are rectangular, the user must simultaneously align the two positioning ends of the reel with the corresponding positioning grooves to put the two positioning ends of the reel into the corresponding positioning grooves respectively. The operation is very troublesome and difficult to achieve. Fully automatic work
