Dead weight type standard force source device with counterweight independently loading and unloading

Abstract

The invention discloses a net-weight type standard power source device which can load and unload weight independently. The invention overcomes the problems of complicated structure, low efficiency, difficult automation and difficult loading and unloading of the weight. The device comprises a stander (26), a suspension(32), a group of weights, and a group of weight electromotion mechanisms (10), wherein, at least two sets of weight electromotion mechanisms (10) corresponding to each weight (12) are distributed evenly and arranged on the upright post of the standers around the weight; when not in working, a sliding block (18) of the weight electromotion mechanisms (10) is contacted with a weight (12). A first number elastic part ( 17) and a elastic part (27) are respectively arranged between the sliding block (18) and the weight (12), and between a pallet (17) and a snap ring component (28); the center position of a soleplate is provided with a anti-oscillating device (13); the lower end of a steeve (7) is inserted between two second rolling bearings (29) of the anti-oscillating device (13) for contacting with or separating from the two second rolling bearings (29).

Description

technical field [0001] The invention relates to a technical device for detecting, testing and calibrating a dynamometer, more specifically, it relates to a static weight standard force source device for independently adding and unloading weights. Background technique [0002] With the rapid development of the economy and the advancement of science and technology, the requirements for force measurement in various industries are getting higher and higher. Take the production and application of load sensors, one of the most representative force measuring instruments, as an example. At present, China is already the largest producer of load sensors in the world, accounting for about half of the world's total output, and the number is tens of millions per year. Calculation, applied to the system represented by weighing. As a force measuring instrument (usually refers to force sensor, load cell, force measuring ring, etc.), its R & D, production, verification and use must use the ...

AI Technical Summary

Problems solved by technology

Not only the structure is complicated, but also the working process is complicated, and the efficiency is difficult to improve

[0008] These weight-applying methods are complex in structure, difficult to improve work efficiency, difficult to realize automatic control of equipment work, especially difficult to realize weight exchange control

For the detection and calibration of various dynamometers, the new standard gives the time requirements for loading and unloading. It is difficult for the traditional deadweight force standard machine to meet these requirements, or it is difficult to meet all the requirements.
