Chuck device for quickly installing rewinding shaft and its installation method

Abstract

The invention discloses a chuck device of a quick mounting winding shaft and a mounting method of the chuck device. The chuck device comprises a driving chuck connected with a sliding shaft on one side, and a driven chuck connected with a sliding shaft on the other side; the driving chuck and the driven chuck are used for jacking the winding shaft, and then the winding shaft is driven by the driving chuck; the driving chuck comprises a driving chuck body, flat keys and elastic structures; the flat keys and the elastic structures correspond to key grooves of the winding shaft; dovetail-shaped sliding grooves for containing the flat keys are formed in the driving chuck body; the flat keys are slidingly arranged in the dovetail-shaped sliding grooves; one side of each flat key is mutually contacted with the driving chuck body, and the other side thereof is mutually contacted with one elastic structure; the flat keys are propped by springs of the elastic structures; the driven chuck comprises a driven chuck body; and the driven chuck body is provided with shaft holes for containing the sliding shafts. The flat keys are fixed to the chuck bodies through the use of the springs, so that a situation that the sliding shafts are manually rotated to be aligned to the flat keys of the driving chuck and the key grooves of the winding shaft is avoided, and the operation danger is reduced.

Description

technical field [0001] The invention relates to the field of installing a chuck for a winding shaft, in particular to a chuck device for quickly installing a winding shaft and an installation method thereof. Background technique [0002] At present, the installation of the winding shaft generally requires an active collet and a passive collet, but the flat key used for the clamping position of the existing active collet is generally fixed on the collet body, and cannot have a certain elastic position torsion. Therefore, when installing the rewinding shaft, at the moment when the installation head of the rewinding shaft is inserted, the flat key is easily damaged during the process of aligning the slot of the rewinding shaft, causing the rewinding shaft to slip, and the winding work cannot be completed. ; and the existing flat keys are all fixed installations, so in the process of installing the winding shaft, it is necessary to manually rotate the position of the keyway in t...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a collet device for quickly installing a rewinding shaft and its installation method, aiming to solve the problem that the existing collet grasping device for installing a rewinding shaft needs to manually rotate the keyway and the flat key of the rewinding shaft when installing the rewinding shaft Corresponding, so the operation is dangerous, and the technical problem of changing the winding speed is slow
