Embodiment 1

[0026] Such as figure 1 , A swing type ignition signal generating device, the swing type ignition signal generating device is installed on the shaft of the swing device of the swing engine, and includes a generating device housing 1 connected to the shaft 10 of the swing device. The pendulum core 4 and the elastic structure 2 in the device housing 1, and the generator housing 1 is preferably cylindrical or rectangular. At least one end of the pendulum core 4 is connected to the inner wall of the generator housing 1 through an elastic structure 2, and a position detection sensor 3 is installed on the outer side of the generator housing 1. The swing type ignition signal generating device also includes a guide rod 5, such as figure 2 Preferably, the elastic structure 2 may be a spring. Of course, the elastic structure 2 may be an elastic structure 2 made of rubber or other elastic materials. There are two elastic structures 2, the pendulum core 4 and the elastic structure 2 are b...

Embodiment 2

[0029] Such as image 3 The swing type ignition signal generating device is the same as the embodiment 1, but the outer side of the generating device housing 1 is also provided with a balance weight 7 and a balance weight placement plate 8 matched with the balance weight 7, and the balance weight The block 7 is connected to the elastic structure 2, and the elastic structure 2 is fixed to the end of the generator housing 1 by a limiting clip 6. Due to the action of the balance weight 7, it can be solved that the static position of the pendulum core 4 is affected by gravity. Specifically, when the swing type ignition signal generating device of the present invention is placed horizontally, the balance weight 7 is affected by gravity. It falls on the generator housing 1 or the counterweight placement plate 8; when the swing type ignition signal generator of the present invention is placed vertically, the balance counterweight 7 is offset by the gravity of the pendulum core 4, at th...

Embodiment 3

[0031] Such as Figure 4 When the swing type ignition signal generating device is used as a rotation speed detection device, it is the same as the embodiment 1, but the pendulum core 4 is provided with a gradient gray plate 9 on the side close to the position detection sensor 3, and the position The detection sensor 3 is an optical fiber sensor, and the position detection sensor 3 is within the range of the gradient gray plate 9 during the movement. Due to the different rotation speed of the swing device, the centrifugal force applied to the pendulum core 4 is also different. The balance position of centrifugal force and spring force is also different. In this way, when the gradient gray scale board 9 is in different positions, its corresponding gray levels are different, and the different rotation speeds of the pendulum core 4 can correspond to different positions of the gradient gray scale board 9. By detecting the intensity of the optical signal returned by the fiber optic se...

Abstract

The invention discloses a swing type ignition signal generation device. The swing type ignition signal generation device is installed on a shaft of a swing device of a swing type engine, and comprisesa generation device shell, a pendulum bob core and an elastic structure, wherein the generation device shell is connected with the shaft of the swinging device, and the pendulum bob core is arrangedin the generation device shell; at least one end of the pendulum bob core is connected to the inner wall of the shell through the elastic structure, and a position detection sensor is installed on theouter side of the generation device shell. The invention further discloses a rotating speed detection device. A gradient gray board is arranged on the side, close to the position detection sensor, ofthe pendulum bob core of the swing type ignition signal generation device, and the position detection sensor is an optical fiber sensor. The invention provides a simple and feasible swing stop pointposition detection device which solves the problem about detection of a swing stop point position of the swing type engine. The detection mode is simple, and the structure is small. According to the rotation speed detection device, the ignition time of the swing device of the swing type engine is judged by using the obtained rotating speed.

Description

Technical field [0001] The present invention relates to the technical field of detecting the ignition position of a swing device of a swing engine, and the present invention also relates to the technical field of detecting the rotation speed of a swing device of a swing engine. Background technique [0002] The swing dead-point detection of the swing device is generally obtained by the motion encoder detection, but the motion encoder signal needs to be compiled and judged by the program. The ordinary engine senses the boss signal fixed on the turntable through the position detection sensor to give the ignition signal. However, for swing devices, especially swing engines, the swing amplitude is variable, and the swing dead point is not fixed, which requires special equipment to obtain the dead point position. The existing method is to give the ignition signal through the motion encoder. When the two pulse signals have the longest time, the motion encoder gives the ignition signal...
