Abstract

The invention discloses a three-jaw chuck locating mechanism. The three-jaw chuck locating mechanism comprises a base, a driving mechanism, a main drive gear and an auxiliary drive gear, wherein outsides of the main drive gear and the auxiliary drive gear are meshed mutually through teeth. The driving mechanism can drive the main drive gear to rotate around the axis of the main drive gear, an empty cavity used for placing to-be-located products is formed in the center of the auxiliary drive gear, three clamping jaws respectively pointing to the center of the auxiliary drive gear are arranged on the outer side face of the auxiliary drive gear at intervals, and the other ends of the three clamping jaws are respectively connected with a sliding block. The sliding blocks are respectively limited to slide in a sliding chute along the radius direction of the auxiliary drive gear, meanwhile, the three clamping jaws are respectively provided with a cam roller, and the other ends of the cam rollers are limited to slide in an arc-shaped sliding chute arranged in the outer side face of the auxiliary drive gear. According to the three-jaw chuck locating mechanism, the driving mechanism sequentially drives the main drive gear and the auxiliary drive gear to rotate, and therefore the three clamping jaws are driven to clamp and loose, and three-point locating is achieved. The three-jaw chuck locating mechanism is high in repeated locating accuracy, strong in clamping force, and good in generality for like products.

Description

technical field [0001] The invention relates to a three-jaw chuck positioning mechanism, which is suitable for clamping and precise positioning of various regular-shaped rotary products. Background technique [0002] At present, the industry generally adopts two parallel clamping jaws for the positioning and clamping mechanism of various specifications of rotary products. This clamping method has the following shortcomings: ①The positioning method is two-point positioning, and the repeat positioning accuracy Limited; ②Limited clamping force; ③Insufficient versatility for similar products of different specifications; ④Limited application range. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a three-jaw chuck positioning mechanism, which can provide repeat positioning accuracy and versatility for rotary products of various specifications and shapes. [0004] The technical solution adopted by the present in...
