Abstract

The invention discloses a tightening shaft screw sleeving detection device. The device comprises a sleeve assembly, a tightening shaft assembly connected with the sleeve assembly, a photoelectric sensor and an induction disk, wherein the photoelectric sensor and the induction disk are installed on the sleeve assembly. The sleeve assembly comprises a third sleeve fixed to the tightening shaft assembly, a second sleeve elastically connected with the third sleeve, and a first sleeve which is fixedly connected with the second sleeve and is matched with a screw, wherein a chamber in sleeving fit with the upper part of the second sleeve is formed inside the third sleeve, a spring is installed in the chamber, the upper end of the spring is fixed to the top wall of the chamber, and the lower end of the spring is fixedly connected with the top of the second sleeve. The photoelectric sensor is fixedly connected with the lower part of the tightening shaft assembly. The induction disk in signal connection with the photoelectric sensor is fixedly connected with the upper part of the outer wall of the first sleeve.

Description

technical field [0001] The invention relates to a mechanical tool, in particular to a detection device for screw insertion of a tightening shaft. Background technique [0002] Screw fastening is the most important fastening method in the assembly industry, and it is the most widely used connection method of parts in industry. Fully automatic screwing machines are currently widely used in the screw fastening process to realize the automatic screwing operation of screws. The working principle of the tightening machine is that several tightening shafts are installed on a fixed platform, and each tightening shaft can screw in or out one screw, so one screwing machine can screw in or out several screws at the same time operate. The tightening shaft is generally composed of a servo motor and a reducer (power source), a torque sensor (to detect the screw-in torque and screw-in angle), a connector and a front-end sleeve (with a spring inside and a certain telescopic length). When...
