Digital adjustable damping handle device and zero point positioning method therefor

Abstract

The invention discloses a digital adjustable damping handle device and a zero point positioning method therefor. The device comprises a support (10), a scale cover (2), a rotating shaft (5), a handle rod (1), a left shaft sleeve (10), a right shaft sleeve (4), a belleville spring (6), a frictional ring (3), a rotary encoder (9), and an operating platform (12). An adjustable damping force is generated through the belleville spring (6). A handle can be positioned at any position in a working section, and an operation force can be adjusted quickly. The device enables an angle input signal to be converted into a digital signal through the rotary encoder (9), carries out the zero point setting and angle conversion of the raw data of the rotary encoder (9), and obtains effective control parameters, thereby controlling a control object. According to the invention, an angle control parameter is converted into a digital control parameter, and the control precision is improved through data processing. The device is simple and reliable in structure, is convenient for damping adjustment, and is long in service life.

Description

technical field [0001] The invention relates to the field of operation control of industrial field equipment, in particular to a digital adjustable damping handle device and a zero point positioning method thereof. Background technique [0002] In the process of industrial field production, more and more users control the operation of the equipment by operating the handle. According to different equipment and different users, it can be adjusted at will, and the device is required to be simple and reliable, and the control precision is high. [0003] Take the operating handle device of the 30,000-ton large-scale forging hydraulic press of the Southwest Aluminum Industry Group in China as an example. The handle control device uses a spring to squeeze the steel ball into the positioning hole for positioning. It can only perform step-by-step positioning and the operating force cannot be adjusted. Point contact and friction with the positioning surface for a long time, the steel...

[0003] Take the operating handle device of the 30,000-ton large-scale forging hydraulic press of the Southwest Aluminum Industry Group in China as an example. The handle control device uses a spring to squeeze the steel ball into the positioning hole for positioning. It can only perform step-by-step positioning and the operating force cannot be adjusted. Point contact and friction with the positioning surface for a long time, the steel ball and the plane wear seriously, the device life is short, and the maintenance cost is high; at the same time, the physical control signal is converted into the rotation angle of the rotary encoder after being amplified by the gear, and the transmission error of the gear transmission and the rotary encoder The installation error makes the zero point deviate from the origin of the distributor gear shaft, resulting in low control accuracy and poor reliability
