Digitalized torque measuring and loading device

Abstract

The invention relates to the technical filed of measurement and value transfer, in particular to a digital torque measuring and loading device which can measure various torque measuring devices. A PC computer or a portable PC computer controls an AC digital servo system. With the technical proposal, the invention solves the problems of being not firm enough of the connection mode, too lower standardized degree, poor reproducibility of the measuring process and relatively large error of the systematical operation of the prior measuring method; and the invention is characterized in that the torque is sampled directly through a motor; the digital torque measuring and loading device adopts a speed, position and intelligent three-shaft positioning system and implements SPC image data conversion analysis; and the invention adopts a network real time filed monitoring and measuring data transmission system to satisfy the requirements of modern diverse measuring technology and to program visual programming software. The invention has the advantages of quickly developing various application programs and WINDOWS type operation interface, increasing the accuracy and precision of the measurement and the reliability of the measured data by utilizing various WINDOWS application programs, avoiding the uncertain discreteness of the system, decreasing the errors caused by manual operation, and being beneficial for the research on the torque measurement.

Description

[technical field]

[0001] The invention relates to the technical field of measurement testing and value transmission, in particular to a digital torque measuring and loading device (primary standard) for verifying various types of torque measuring instruments (secondary standard). [Background technique]

[0002] At present, the verification of various types of torque measuring instruments is completed by using torque sensors with temporary mechanical benches. This traditional verification method has problems such as unstable connection, low degree of standardization, poor reproducibility of the detection process, and large system operation errors, which affect the correct transmission of measurement values. [Content of the invention]

[0003] The technical problem to be solved by the present invention is to provide a stable performance, high degree of standardization, excellent reproducibility, small system operation error, serial connection of standard torque measurement a...

Examples

Embodiment 1

[0006] Embodiment 1: with reference to accompanying drawing. The main frame of the machine in this embodiment adopts the gantry plus platform chute structure, the loading head is at the upper center of the gantry, and can be adjusted arbitrarily within the range of 90° vertically and horizontally to the horizontal plane, and the angle adjustment is electric adjustment, with automatic And manual adjustment button, just input the angle to be adjusted in automatic mode, and press the button until the set angle is reached in manual mode, and release it, and it is designed with anti-loose locking mechanism, which can be adjusted at 90°~0° Lock at any angle.

Embodiment 2

[0007] Embodiment 2: with reference to accompanying drawing. This embodiment adopts an automatic centering device. When the tested instrument is placed on the clamping position of the platform, press the clamping button and the tested instrument is automatically clamped. The position of the tested instrument on the horizontal plane can be automatically adjusted by the laser scanning system to the center of the loading part of the tested instrument. That is to automatically make the loading rotation axis of the tested instrument coincide with the power loading rotation axis; during the test, the laser scanning system first automatically scans the position difference between the current position and the active loading axis, and the system automatically adjusts the position left and right, front and back according to the difference. The loading axis of the tested instrument coincides with the power loading rotation axis.

Embodiment 3

[0008] Embodiment 3: with reference to accompanying drawing. This embodiment adopts dual control of computer and man-machine interface, both of which can simultaneously display various values ​​such as speed, torque, time, etc., and the computer can also display various related change curves, and all display signals come from DEWE-DSA series dynamic signal analyzers . When the computer is turned on, the computer takes priority control, and the man-machine interface touch screen only displays the content. When the computer is not turned on, the man-machine interface touch system can control the entire system and also undertake the display work. The two do not interfere with each other and form a self-contained system.
