Multi-station locating method and multi-station mechanism for implementing multi-station locating method

Abstract

The invention discloses a multi-station locating method and a multi-station mechanism for implementing the multi-station locating method. The multi-station locating method comprises the steps that when all tooth surface sections of an incomplete driving gear are sequentially meshed with a complete driven gear one by one, the number of rotation turns of the driving gear is not larger than one, and an operation shaft is driven by the driven gear to complete sequential switching between all stations. According to the multi-station locating method, under the condition that the number of rotation turns of the output driving gear is not larger than one, the tooth surface sections on the output driving gear are sequentially meshed with the output driven gear one by one, so that the operation shaft is driven by the output driven gear to complete sequential switching between all the stations; in this way, when the operation shaft completes sequential switching between all the stations once, each tooth surface section on the output driving gear is meshed with the output driven gear only once, and therefore the phenomenon that in the process of switching between all the stations, the tooth surface sections of the output driving gear need to be repeatedly meshed with the output driven gear is avoided; and besides, the loss speed of the incomplete gear is reduced, and the service life of the output driving gear is prolonged.

Description

technical field [0001] The invention relates to a multi-station positioning method and a multi-station mechanism implementing the method. Background technique [0002] At present, the traditional multi-station positioning method is to transmit power through continuous motion, and the position accuracy when reaching the working position is determined by the accuracy of parts assembly and processing. When the accuracy of the parts does not meet the requirements, it can only rely on the assembly angle and position of the adjustment mechanism to meet the accurate positioning requirements of the mechanism. Therefore, the traditional multi-station positioning method has the disadvantage of requiring high precision in the manufacture and assembly of the action elements of the mechanism. [0003] Chinese patent document CN100466126C discloses a multi-position electric operating mechanism, including a transmission mechanism that is connected between the motor and the operating shaft...

Problems solved by technology

But because there are only one or two tooth surface segments on the driving gear, so in order to complete the switching of more than three stations within 360° for driving the driven gear, the amount of rotation of the driving gear needs to be more than one turn, which will cause One or all of the tooth surface segments on the driving gear need to mesh with the driven gear more than twice, and are affected by the characteristics of large rigid impact in the transition process of the incomplete gear transmission mechanism between the moving state and the static state, and The tooth surface section of the driving gear meshed with the driven gear for many times will have the disadvantage that the damage speed is faster than that of the other tooth surface sections, which will lead to the accelerated damage speed of the entire driving gear, shorten the service life of the driving gear, and reduce the number of incomplete gears.
