Slide type hand-operated safety chuck convenient for placing, clamping and taking out extended and retracted roll materials

Abstract

The invention discloses a slide type hand-operated safety chuck convenient for placing, clamping and taking out extended and retracted roll materials. The slide type hand-operated safety chuck comprises a supporting end safety chuck and a power end safety chuck, wherein a reel mandrel is blocked and matched between a short shaft groove block of the supporting end safety chuck and a long shaft groove of the power end safety chuck through an insert; a long shaft and a short shaft can be adjusted, so that mounting and using errors can be compensated, and therefore, mandrels of different lengths are adapted; the slide type hand-operated safety chuck is great in bearing capacity, is manufactured from high-quality steel, greatly increases bearing weight through a special structure, is long in use time, is simple in maintenance, adopts blocking hole high-frequency quenching treatment, is convenient in maintenance as parts can be interchanged for use, is high in using precision, enables partsto be wear-resistant by chromium plating, blackening and quenching, is high in part precision, is strong in anti-deforming capability, is small in circular run-out, is high in safety, is dustproof andprevents clamp injury as a circular disc is equipped with a rubber ring, is prevented from dropping as a blocking hole is equipped with an axial positioning ring, is strong in applicability, adopts adetachable blocking hole, replaces different types, and is suitable for a precise high-rotation-speed occasion.

Description

technical field [0001] The invention relates to the technical field of winding and unwinding machinery, in particular to a sliding type manual safety chuck that facilitates the placement and removal of winding and unwinding materials. Background technique [0002] According to the type, the safety chuck can be divided into shaft seat type, flange type, or horizontal installation and vertical installation. The simple, practical and easy-to-install design of the standard safety chuck provides fast, safe, reliable and simple coupling and disengagement operations for frequent actions such as coupling transmission and disengagement. [0003] Since the current manual safety chuck is composed of a support end safety chuck and a transmission end safety chuck, and the roller mandrel is clamped between the support end safety chuck and the transmission end safety chuck, the length specifications of the mandrels are different. , and the shortening of the mandrel end due to wear and oth...

AI Technical Summary

Problems solved by technology

[0003] Since the current manual safety chuck is composed of a support end safety chuck and a transmission end safety chuck, and the roller mandrel is clamped between the support end safety chuck and the transmission end safety chuck, the length specifications of the mandrels are different. , and the shortening of the mandrel end due to wear and other reasons, resulting in a gap between the chuck and the mandrel, the torque transmitted from the driving safety chuck to the mandrel will increase, and the winding will be uneven. Or increase the swing range of the roll when unwinding, which will bring inconvenience to the subsequent production and lead to a decline in product quality, etc.
