Vibration resistance incremental electronic pulse generator

Abstract

The invention discloses a vibration resistance incremental electronic pulse generator. The vibration resistance incremental electronic pulse generator comprises a jump ring. A needle roller is arranged beside the jump ring; the two side edges of the needle roller are provided with a baffle plate groove; the needle roller is engaged with a gear; the center of the gear is provided with a rotating shaft higher than the surface of the gear; the gear is sleeved on the upper portion of the rotating shaft; a moving raster sheet is sleeved on the lower portion of the rotating shaft; an integral optical coupler with an emission receiving device is disposed between the gear and the moving raster sheet; and the integral optical coupler is connected with a signal conversion output device. The vibration resistance incremental electronic pulse generator also comprises a single-chip microcomputer. The single-chip microcomputer (core program) is a key to controlling the pulse generator to accurately emit pulses. The advantages are as follows: during a use process of the generator, the pluses are not generated in case of vibration shaking (mechanical oscillation, shaking back and forth of human hands (a distance between two clicking points)); and the pulses are correctly generated in case of electromagnetic interference.

Description

technical field [0001] The invention relates to a pulse generator, in particular to an incremental electronic pulse generator. Background technique [0002] The original generator is completely mechanically triggered. After the action of the photocell and the grating, the corresponding signal is directly output from the corresponding port. There is no verification or intervention processing on the output signal, so that there is no signal when the signal should not be sent. When the signal is sent, when the signal needs to be sent, the wrong signal is sent. The main manifestations are as follows: 1. The generator generates pulses during some vibrations of the random bed (the displacement data is beating); 2. The data is found to be beating, and the generator is intervened by hand, and the data stops beating. The above-mentioned factors that affect the accuracy are mainly: the outer diameter of the needle roller cannot completely match the inner diameter of the baffle groove...

AI Technical Summary

Problems solved by technology

[0003] like Picture 1-1 , Figure 1-2 As shown, the influence of machining accuracy and assembly factors on the accuracy, the greater the difference between the outer diameter of the needle roller 2 under the circlip 1 and the inner diameter of the baffle groove 3, the greater the left and right swing of the generator, and the greater the impact on the generator. Figure 1-2 The greater the effect of the KC interval above, the consequence is that the high-frequency signal of phase A or B will appear in this interval, so that an error signal will be sent out, and the needle roller of the generator will gradually wear out during use, then this interval will change. bigger, so that the generator shakes more, so that the probability of generator error becomes greater
