High-precision mountable and dismountable potentiometer and use method thereof

Abstract

The invention discloses a high-precision mountable and dismountable potentiometer. The potentiometer comprises a shell, an output shaft is mounted at the lower part in the shell, a connecting shaft ismounted in the middle of the shell of the potentiometer in a penetrating manner, two guide plates are connected to the upper part in the shell in a front-back sliding manner, and two oblique grooveswhich are symmetrically formed are formed in the surfaces of the guide plates; the guide plates are slidably connected with sliding columns through the oblique grooves, the end portions of the slidingcolumns are fixedly connected with first limiting columns, the upper portion of the shell is provided with first through holes allowing the first limiting columns to penetrate out and transversely slide, and thepotentiometer further comprises a pressing block and a transmission mechanism, and the pressing block is driven to vertically move while rotating under the action of the transmission mechanism through the movement of the two sliding columns; and the potentiometer also comprises a driving mechanism used for driving the two guide plates to move forwards and backwards. The potentiometer has the effect of conveniently mounting and dismounting the potentiometer, and solves the problem that the potentiometer is generally mounted directly through welding or bolts and is relatively complicated to dismount and mount.

Description

technical field [0001] The invention relates to the technical field of potentiometers, in particular to a high-precision mountable and detachable potentiometer and a method for using the potentiometer. Background technique [0002] The electric actuator is the execution equipment of the automation instrument terminal, and is usually used to open or close the execution drive device for adjusting the opening of the valve. In today's computer control system, the reliability and stability of software and hardware are already very high, so the stability and control accuracy of the actuator have become an important link in the automatic control system. The potentiometer in the electric actuator is an important sampling component in the actuator, and the decoupling of its installation position directly affects the sampling accuracy and stability of the electric actuator. [0003] In the prior art, the potentiometer is usually installed directly by welding or bolts, which is cumber...
