Automatic centering electric rotating chuck

Abstract

Disclosed is an automatic centering electric rotating chuck. The automatic centering electric rotating chuck comprises a base; a bearing seat is arranged on the base; bearings are disposed in the bearing seat; inner rings of the bearings are connected with a roll core; one end of the roll core is connected with a roll core driving device, and the end wall of the other end of the roll core is provided with two sets of clamping jaw mechanisms which are arranged in a cross shape; the first set of clamping jaw mechanisms includes two clamping jaw mechanisms which are arranged in a longitudinal symmetry mode, and the second set of clamping jaw mechanisms includes two clamping jaw mechanisms which are arranged in a left-right symmetry mode; at least one clamping jaw mechanism of each set of clamping jaw mechanisms is provided with a sensor; a through hole is formed in the center of the roll core; a first cavity and a second cavity are formed in the wall of the roll core; an electric conductive sliding ring is disposed in the first cavity; two clamping jaw driving mechanisms for driving the first set of clamping jaw mechanisms and the second set of clamping jaw mechanisms correspondingly are disposed in the second cavity; and the electric conductive sliding ring is connected with the clamping jaw driving mechanisms through conducting wires. The automatic centering electric rotating chuck has the advantages of achieving through hole clamping, being provided with two sets of clamping jaws, achieving automatic and reliable centering and complete rotation, and the like.

Description

[0001] Technical field:

[0002] The invention relates to the technical field of rotary chucks, in particular to an automatic centering electric rotary chuck.

[0003] Background technique:

[0004] The rotary chuck is one of the most important parts of the pipe cutting machine. When the pipe profile is processed, it is usually clamped by two chucks for cutting. The two chucks rotate synchronously during cutting, and one of the chucks can translate along the axial direction. The head cooperates to complete the three-axis linkage of X, Y, and Z to meet the cutting shape we need. The existing pipe cutting machines basically use the above working principle. The two chucks used in the existing pipe cutting machines are a rotary chuck and a sliding chuck. The rotary chuck is usually a four-jaw blind-hole rotary chuck, and the sliding chuck is a through-hole chuck. For the laser head of the pipe, the use of the four-jaw blind hole rotary chuck has the following disadvantages. First,...
