1. Description
The full name of the four-jaw self-centering chuck is a manual
four-jaw self-centering chuck for machine tools. It consists of a
disc body, four small bevel teeth and a pair of jaws. The four
small bevel teeth are engaged with the coil wire, the back of the
coil wire has a flat thread structure, and the claws are equally
installed on the flat thread. When the small bevel tooth is pulled
with a wrench, the coil will rotate, and the flat thread on the
back of it will make the claw approach or withdraw to the center at
the same time. Because the pitches of the flat rectangular threads
on the coiled wire are equal, the movement distances of the four
claws are equal, which has the effect of automatic centering.
There are two types of jaws of the four-jaw self-centering chuck,
including integral jaws and separate jaws. The overall claw is a
claw that integrates the base claw and the top claw, and a pair of
overall claw is divided into four positive claws and four reverse
claws. A pair of separation claws has only four claws, and each
claw is composed of a base claw and a top claw. In addition, soft
jaws can also be provided according to user requirements, and high
centering accuracy can be obtained after random configuration
(grinding) to meet the clamping requirements.
The jaws of the four-jaw single-action chuck have only one type of
integral jaw. One jaw can move independently for clamping eccentric
and irregularly shaped parts.
