Problems solved by technology

The traditional way to measure the coaxiality of the hexagonal shaft is to clamp the hexagonal end in the three-jaw chuck of the lathe, and then use the dial indicator to measure the runout of the piston pin on the hexagonal shaft. This method requires high operation and will produce Big error, time-consuming and labor-intensive

Abstract

The invention provides a coaxiality detector. The coaxiality detector is used for detecting the coaxiality of a hexagonal shaft, and comprises a base, a clamping mechanism, a slewing mechanism and a detection device, wherein the clamping mechanism is used for clamping the hexagonal shaft; the slewing mechanism is movably arranged on the base, and is used for supporting and driving the clamping mechanism to rotate around the central axis of the hexagonal shaft; and the detection device is arranged on the base and is used for detecting the coaxiality of the hexagonal shaft. The coaxiality detector provided by the invention adopts a precision three-jaw chuck and is connected with the base through a bearing, so that the precision three-jaw chuck cannot jump when the precision three-jaw chuck rotates in the center of the base freely; and simultaneously, the hexagonal shaft is clamped on and detached from the three-jaw chuck very conveniently; the installation error is low; and the detection precision is improved.

Description

technical field [0001] The invention relates to a coaxiality detector, in particular to a coaxiality detector for detecting hexagonal shafts. Background technique [0002] The hexagonal shaft is an important part of the car, which is welded by the piston pin and the hexagonal body, and has high requirements for coaxiality. The traditional way to measure the coaxiality of the hexagonal shaft is to clamp the hexagonal end in the three-jaw chuck of the lathe, and then use the dial indicator to measure the runout of the piston pin on the hexagonal shaft. This method requires high operation and will produce Big error, time-consuming and labor-intensive. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a coaxiality detector with fast clamping, small installation error and high detection accuracy. [0005] (2) Technical solutions [0006] In order to solve the above techni...
