[0044] Example 1
[0045] Figure 1 The following is a schematic structural diagram of a valve clearance measuring device provided by an embodiment of the present disclosure. As Figure 1 shown, a valve clearance measuring device includes:
[0046] A housing 1; a measuring mechanism 2; a driving motor 3; a processing and control mechanism 4; the measuring mechanism 2 is arranged inside the housing 1 and is slidably connected to the housing 1, and is adapted to measure the clearance of the valve; the driving motor 3 is drivingly connected to the measuring mechanism 2 and is adapted to provide driving force for the measuring mechanism 2 to move inside the housing 1; the input end of the processing and control mechanism 4 is electrically connected to the output end of the measuring mechanism 2, and the output end of the processing and control mechanism 4 is electrically connected to the control end of the driving motor 3.

[0047] It should be noted that the driving motor 3 can be a servo motor.
[0048] In this embodiment, through the valve clearance measuring device, non-contact measurement of the valve clearance can be realized, it is not easy to damage the device to be measured, and the measurement accuracy and measurement efficiency can be improved.
[0049] Example 2
[0050] Based on the above embodiments, a slide rail bolted to the top of the housing 1 is provided inside the housing 1. The connection end of the slide rail is slidably connected to the measuring mechanism 2. The slide rail is adapted to control the moving direction of the measuring mechanism 2 so that the measuring mechanism 2 moves along the long side direction of the housing 1. A hole is formed at the bottom of the housing 1 for the measuring mechanism 2 to expose.
[0051] It should be noted that the housing 1 can be made of titanium alloy. The titanium alloy material has high strength, enabling the housing 1 to withstand a large amount of stress; it has strong corrosion resistance, making the housing 1 not easily damaged and having a longer service life; it has a small density. For the same volume, the titanium alloy housing is lighter, facilitating the lifting of the housing to measure the valve clearance. The number of the holes can be two, and the shape and size of the holes can be set according to the actual needs of the measurement site.
[0052] Figure 2 This is an overall appearance structure schematic diagram of a valve clearance measuring device provided by an embodiment of the present disclosure.

[0053] Example 3
[0054] Figure 3 This is a structure schematic diagram of the measuring mechanism provided by an embodiment of the present disclosure. As Figure 3 shown, based on the above embodiments, the measuring mechanism 2 includes: a laser displacement sensor 21, and the laser displacement sensor 21 is adapted to measure the clearance of the valve through laser.
[0055] It should be noted that the laser displacement sensor 2 can adopt an industrial-grade laser displacement sensor. The laser displacement sensor 21 can be set to two, and each laser displacement sensor corresponds to a measured object.
[0056] The linearity of the laser displacement sensor 21 can reach 1 micron, the resolution can reach 0.1 micron, the responsivity can reach 9.4 kHz, the operating temperature range is -20°C to 120°C, the body size is the effective stroke plus 43 mm, the service life is greater than 100 times 10^6 times, or 2 times 10^6 meters, the operating humidity is less than or equal to 90%, the temperature drift coefficient is less than or equal to 1.5 PPM / °C (1.5 parts per million per degree Celsius change), the shock coefficient is: IEC68-2-29:1968 50g, where IEC68-2-29:1968 is an environmental test standard, and 50g means it can withstand an impact of 50 times the acceleration of gravity. The vibration coefficient is: IEC68-2-6:1982 20g, where IEC68-2-6:1982 is an environmental test standard, and 20g means it can withstand a vibration of 20 times the acceleration of gravity. The electrical interface can be a five-wire system with a shielding layer design. It can adapt to harsh environments, has high precision, high repeatability, high reliability, strong environmental adaptability, low channel cross-interference, strong shock resistance, long service life, and a large temperature range in which it can work properly.
[0057] In this embodiment, the laser displacement sensor 21 measures the clearance of the valve through laser, which can realize non-contact measurement of the valve clearance. During the measurement process, there is no need to contact the valve, so it is not easy to damage the valve. The measurement method is scientific, convenient, safe and reliable, and can improve the measurement accuracy and efficiency.

[0061] In this embodiment, the control end of the rotary cloud platform 22 is detachably connected to the connection end of the laser displacement sensor 21. The rotary cloud platform 22 can be used to control the small-range position adjustment of the laser displacement sensor 21, and at the same time, it can ensure that the laser displacement sensor 21 reduces jitter during the measurement process, making the fuselage more stable, thereby reducing the measurement error and improving the measurement accuracy.
[0062] The emission lens 23 is telescopically connected to the laser displacement sensor 21 through a connecting rod. In this way, the distance between the emission lens 23 and the laser displacement sensor 21 can be adjusted, so that the emission lens 21 can keep the laser emitted by the laser displacement sensor 21 focused at the position with the smallest contact area with the measured point, thereby improving the measurement accuracy and keeping the measurement error within 0.001 millimeters.
