The invention discloses an automatic centering chuck with excellent performance and simple structure. According to the technical scheme, the automatic centering chuck is characterized in that the automatic centering chuck comprises a chuck body and a plurality of claws; a first chute is formed on the chuck body; the claws include rotating rods and abutting wheels; the first chute is arranged spirally; the distance dimension from the center of the chuck body to the first chute is gradually shortened along the length direction of the first chute; the chuck body rotates in the circumferential direction and is connected with a driving device; the driving device includes an upper bracket, a lower bracket and a support rod; the upper bracket includes an upper sliding arm; the lower bracket includes a lower sliding arm; the support rod is fixedly connected to the ends between the upper sliding arm and the lower sliding arm in a support mode; a rotating wheel is connected with the support rodin a rotating mode; the upper sliding arm is provided with a second chute; the lower sliding arm is provided with a third chute; and the upper bracket and the lower bracket can push rotating rods to slide along the length of the first chute, the second chute and the third chute during synchronous rotation so as to be close to or away from the center of the chuck body.
Description
technical field [0001] The present invention relates to a clamping device, more specifically, it relates to a self-centering chuck. Background technique [0002] At present, after the common chuck clamps the workpiece, the calibration process is complicated, takes a long time, and the accuracy is difficult to guarantee. Although the hydraulic automatic centering chucks sold on the market can also achieve the purpose of fast clamping and automatic centering, However, the price is expensive, and there is an urgent need for a self-centering chuck with excellent performance and a reasonable price to meet market demand. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a self-centering chuck with excellent performance and simple structure. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a self-centering chuck, including a chuck body ...
