Reversing device, shock absorber dynamometer pull force value calibration device and calibration method

Abstract

The invention discloses a reversing device, in particular to a force conversion device. The reversing device comprises a lower connection plate, a lower fixed rod, a location plate, an upper connection plate, an upper fixed rod and a press plate. A location plate through hole is arranged on the location plate, a press plate through hole is arranged on the press plate, the upper end of the lower fixed rod is connected with the press plate, the lower end of the lower fixed rod is connected with the lower connection plate, and the middle of the lower fixed rod is connected with the location plate. The upper end of the upper fixed rod is connected with the upper connection plate, the lower end of the upper fixed rod is connected with the location plate, and the middle of the upper fixed rod is connected with the press plate. The lower fixed rod penetrates through the location plate through hole, and the upper fixed rod penetrates through the press plate through hole. Compared with the prior art, the reversing device is capable of converting pull force received by a shock absorber sensor into pressure received by a dynamometer, so that pull force value received by the sensor can be read from the dynamometer. Pull force value calibration of a power indication machine of the shock absorber is achieved, and the problem that pull force value calibration of the power indication machine troubles the industry for many years can be resolved accordingly.

Description

technical field [0001] The invention relates to a shock absorber dynamometer calibration tool and method, in particular to a reversing device, a shock absorber dynamometer pull force value calibration device and a shock absorber dynamometer pull force value calibration method. Background technique [0002] The shock absorber dynamometer is mainly used to test the damping force of the shock absorber during tension and compression. This test is the only comprehensive performance test index that reflects the final assembly of the shock absorber components. It plays the role of final quality check on the product. [0003] For a long time, the industry generally only calibrates the compression force value of the shock absorber dynamometer. The method is to rotate the screw handle of the shock absorber dynamometer lead screw fixed on the shock absorber dynamometer beam to drive The shock absorber dynamometer sensor on the shock absorber dynamometer crossbeam presses against the d...

AI Technical Summary

Problems solved by technology

However, because the space between the shock absorber dynamometer sensor under the shock absorber dynamometer crossbeam and the shock absorber dynamometer spindle platform is too narrow, generally only tens of kilograms can be hung. The following disadvantages will occur: one is to lift tens of kilograms of weight to a height of about 1.6 meters, and then hang it on the sensor of the shock absorber dynamometer, which is more difficult; Once the lanyard breaks, the height of 1.6 meters drops dozens of kilograms of weights, and the people, machines, and weights are all vulnerable to damage; the third is that the accuracy is poor, because the full scale of most shock absorber dynamometers is 1000 About kilograms, if the full scale is evenly distributed at 5 points for calibration, you need to hang 200 kilograms, 400 kilograms, 600 kilograms, 800 kilograms and 1000 kilograms in sequence. If you only hang dozens of kilograms of weights for testing, the accuracy is obvious. Debatable

However, the small space under the sensor of the shock absorber dynamometer cannot accommodate the above-mentioned hundreds of kilograms of weight, and it is very difficult to hang such a heavy weight at a height of 1.6 meters.

Therefore, it is inappropriate to use the method of hanging weights to calibrate the force value of the shock absorber indicating machine
