Description
Technical Field
The invention relates to the technical field of machinery, in particular to a guided safety chuck.
Background
The standard safety chucks commonly used in the market rely on the friction force generated between the spring and the steel ball to ensure that the disc does not open during operation, but the friction force is limited. For various reasons, the disc is in a semi-open state in the running process and is in dry friction with a self-locking inclined surface of the safety chuck, so that a large amount of metal scraps are generated. The conventional safety chuck has a large force for opening the disc because of friction between the spring and the steel ball (if the diameter of the material is large, the operator has a relatively difficult time stretching the force to open the disc). The standard square chuck needs to be driven and positioned, the matched part of the 90-degree expansion shaft of the chuck and the dragging port of the chuck can be impacted every time the chuck rotates, and the gap can be easily enlarged in use. The larger the gap, the worse the stability of the material during operation, and the larger the channeling.
Therefore, direct-push safety chucks are currently used in the market, because most of the problems of fitting accuracy are round, torque is transmitted through the saddle pin, which is generally trisected. The smaller and trisected pin results in the alignment of the alignment shaft to be aligned when the inflatable shaft is placed on the collet ports, which is time consuming. The shaft is not well put in place, time and effort are wasted, efficiency is low, and meanwhile, the matching precision is damaged due to collision caused by misalignment.
