Embodiment

[0028] A new type of photoelectric speed sensor test equipment, see figure 1 , figure 2 , The servo motor 13 is installed horizontally on the top of the frame 1, the output shaft of the servo motor 13 is connected to one end of the rotating shaft 2, and the other end of the rotating shaft 2 has a square hole. The shaft end of the grating rotating shaft of the photoelectric speed sensor 16 under test extends into the square hole, and when the rotating shaft 2 rotates, the square hole drives the shaft end of the grating rotating shaft of the photoelectric speed sensor 16 under test to rotate. The rotating shaft 2 is connected to the frame 1 through two bearing blocks.

[0029] The vibration generating device adopts two-dimensional vibration.

[0030] The motor 10 is a speed-regulating motor, which is vertically installed on the lower part of the frame 1. The output shaft of the motor 10 faces upwards, and is hinged with one end of the box-shaped transverse sliding seat 6 thro...

Abstract

The invention relates to a test device of a photoelectric revolution speed transducer and aims to test the accuracy, reliability and durability of the photoelectric revolution speed transducer under the condition of simulating a practical running state of a motor vehicle. The test device comprises a test electric device and a mechanical power device, wherein the test electric device comprises an industrial personal computer, an alternating current servo transmission system and a motor speed regulating system; and the mechanical power device comprises a rack, a basic revolution speed generating device arranged on the rack and a at least one-dimensional vibration generating device. The novel test device has reliable test result, high test accuracy, convenient use and strong adaptability.

Description

technical field [0001] The invention relates to a test device, more specifically, the invention relates to a test device for a photoelectric rotational speed sensor. Background technique [0002] At present, my country has entered the era of high-speed rail, and the requirements for various sensors are getting higher and higher. For example, the photoelectric speed sensor requires long-term reliable use under the harsh conditions of locomotive running bumps. This requires that when designing and producing this type of photoelectric speed sensor, not only the conventional measurement accuracy test should be carried out, but also the test should be carried out under the bumpy state of the simulated locomotive operation to verify the reliability and durability of the sensor. [0003] The Chinese Patent Office announced a CN2867349Y document on February 7, 2007, which is called a locomotive speed sensor detection device. The locomotive speed sensor detection device provided by t...
