A propulsion system capable of automatic positioning

Abstract

The invention provides a propulsion system capable of automatic positioning, including: motor (1), pinion gear (2), large gear (3), propulsion screw (5), elastic positioning pin (6), trigger switch system (4 ) and the frame, and the elastic positioning pin (6) is fixed on the frame, and the elastic positioning pin (6) can be pressed to the large gear (3) under the action of elastic force, and can ) on the positioning hole is rotated to the position opposite to the elastic positioning pin (6) and inserted into the positioning hole under the action of the elastic force; a trigger switch system (4) is provided in the two positioning holes for When the elastic positioning pin (6) is inserted into the positioning hole, power off the motor (1).

Description

technical field [0001] The present application relates to a propulsion system, in particular to a propulsion system capable of automatic positioning. Background technique [0002] The propulsion system can be applied in various fields, as long as the device needs to perform linear reciprocating motion, the propulsion system can be applied. In the prior art, the propulsion system is powered by a motor or manually, positioned through gear meshing, and the screw mechanism propels the object. Due to the concealment of the positioning hole in the gear, the manual operation requires the operator to have certain experience to accurately judge the corresponding relationship between the rotation amount and the stroke, and to accurately judge the completion status of the positioning, which will inevitably produce certain errors, resulting in incorrect positioning. Reliable, low accuracy. Although using the motor to provide positioning power can save manpower, it still needs to judge...

AI Technical Summary

Problems solved by technology

Due to the concealment of the positioning hole in the gear, the manual operation requires the operator to have certain experience to accurately judge the corresponding relationship between the rotation amount and the stroke, and to accurately judge the completion status of the positioning, which will inevitably produce certain errors, resulting in incorrect positioning. Reliable, low accuracy

Although using the motor to provide positioning power can save manpower, it still needs to judge the completion status of the positioning manually, the operation is complicated, and the technical requirements for the operator are still relatively high.
