The laser 11 is located at the center of the detection plate 12. The laser light emitted by the laser 11 is perpendicular to the surface of the detection plate 12. The laser 11 is fixedly connected with the detection plate 12. The surface of the detection plate 12 is sequentially provided with a nanometer resistance layer and a photosensitive film. The two can cooperate to receive and identify the specific light point position. The angle deflection amount of the detection plate 12 is obtained through the processing and analysis of the processor, and then the driver 16 is started to perform angle deflection on the detection plate 12. At this time, the detection plate 12 obtains the specific position and posture of the detected part.

[0042] Further, see Fig. 2 A clamping block or other limiting structure can be arranged at a relative position of the inner wall of each small hole, which needs to be matched with the height adjusting piece 15, so as to fix the height adjusting piece 15, for example, a plurality of limiting blocks are sequentially arranged in the longitudinal direction of the inner wall of the plurality of small holes, the plurality of limiting blocks are arranged at equal intervals, and a plurality of clamping grooves are arranged in the longitudinal direction of the columnar wall of the height adjusting piece 15, the position of the height adjusting piece 15 is fixed based on the clamping block and the clamping groove when the height adjusting piece 15 is moved, preferably, each small hole is a threaded hole, and the height adjusting piece 15 is a screw rod matched with the threaded hole, which is simple and easy to operate and has high efficiency.

[0043] Further, see Fig. 2 The inner ring plate 14 is fixed to the position of 1 / 2 of the height of the inner wall of the outer ring frame 13, and the height of the height adjusting piece 15 is preferably less than the height of the outer ring frame 13, each height adjusting piece 15 can be a stepping motor 24 independently controlled to rise and fall by a processor, and is respectively connected to a driver 16 through a lead wire 23, in this way, the adjusting space is not limited, and other components are not interfered, so as to improve the adjusting efficiency.

[0044] Further, the processor is electrically connected with the nanoresistance layer and the laser 11, and can be electrically connected by the lead 23. The processor is configured to receive the light point position detected by the nanoresistance layer and the distance between the laser light source and the piece to be detected. The distance between the light point position and the exit point position of the laser 11 and the distance between the exit point of the laser 11 and the piece to be detected are analyzed to determine the angle deflection amount of the detection plate 12. It can be understood that the processor is programmed to perform corresponding adjustment actions according to the specific operation of the device. The algorithm is mainly used to complete the programming of parallel adjustment. The specific algorithm can be set by a person skilled in the art, and will not be specifically introduced here.

[0045] See Fig. 2 The device also includes a display screen 19, a power supply device 17, and an instrument panel 20. The power supply is electrically connected with the display screen 19 and the driver 16, and can be electrically connected by the lead 23. The display screen 19 is used to realize the input and prompt interface of human-computer interaction, so that the device is more intelligent. The instrument panel 20 is used to protect the internal components, and has a switch-on / off key 18 and a display screen 19 connected thereto. The switch-on / off key 18 is used to realize the operation of starting and shutting down.

[0046] Further, see Figs. 1-2 In order to protect the integrity of the above-mentioned components, preferably, a shell 21 is further included. The shell 21 has a first space and a second space, and a partition plate is arranged between the first space and the second space. The partition plate has a through hole at the middle position, and the size of the through hole is greater than or equal to the size of the point laser light source. The outer ring frame 13 is fixed on the partition plate by bolts 22, or is glued or welded. The detection plate 12 is located in the second space, the laser 11 passes through the through hole to enter the first space, and the exit point of the laser 11 and the detection plate 12 are located on the same plane. The display screen 19 is located in the first space. The instrument panel 20 is electrically connected with the power supply device 17, and the instrument panel 20 is arranged on the outer surface of the shell 21. In order to facilitate the user to carry, handles are arranged at the opposite positions of the outer part of the shell 21. The handles can be two same parallel plates, or two same arc structures, which are not limited here. See Fig. 1 .

[0047] Further, in actual operation, since the laser light is perpendicular to the detection plate 12, the distance L between the detection plate 12 and the surface of the object to be detected is first measured, at this time the laser 11 has a ranging function to obtain data L, or the data L is measured manually, and the value of L and the parallel accuracy of the device are input into the system through the interactive interface; after the laser light is reflected by the surface of the object to be detected, if it returns to the laser 11 along the original path, the surface of the object to be detected and the detection plate 12 are parallel to each other, if the surface of the object to be detected and the detection plate 12 are not in a parallel state, but are deflected by an angle w, then the light emitted from the laser 11 is deflected by an angle of 2w after being reflected by the surface of the object to be detected, the intersection of the reflected light and the detection plate 12 is point A, the geometric center of the detection plate 12 is the emission point of the laser 11, which is point O, and it is assumed that the distance of the OA line segment detected by the nanoresistor layer and the photosensitive plate on the surface of the detection plate 12 is Δd, and the angle value of w can be calculated by solving the triangle as w = arctan {(Δd / 2) ÷ L}.

[0048] The above calculation result is executed by an algorithm in the processor, and the processor starts the driver 16 to execute the angle deflection of the detection plate 12 on the height assembly, when the angle deflection is executed, the laser light emitted by the nanoresistor layer and the photosensitive plate on the surface of the detection plate 12 receives the laser light emitted by the laser 11 after being reflected by the surface of the object to be detected, and the reflected light point A deviates from the side of point O, which is the side where the detection plate 12 is higher relative to the surface of the object to be detected, the integral part of the detection plate 12 and the laser 11 needs to be rotated by an angle w around the axis perpendicular to the reflecting surface and downward, so as to make the detection plate 12 approach parallel to the surface of the object to be detected, and the direction of the deflection angle is opposite to the direction of the reflected light deviating from the center O of the detection plate 12.

[0049] Through multiple cycle operations, when the execution standard is reached, the "locking" option can be selected from the operation interface in the display screen 19, that is, the relative position of the detection plate 12 at this time in the device is locked, and the position and posture of the object to be detected are obtained, and then only the positions and postures of the subsequent multiple parallel surfaces need to be adjusted to be parallel to the detection plate 12. After that, the parallel detection device 10 emits a collimated laser beam, and the operator can adjust the position and posture of the subsequent parallel surface, when the reflected light reflected by the object to be detected is detected again by the nanoresistor layer and the photosensitive film on the surface of the detection plate 12, the display screen 19 of the parallel detection device 10 will prompt "parallel" or emit a beeping sound to indicate that the parallel surface is parallel to the detection plate 12. The device effectively improves the efficiency and accuracy of detection, has strong applicability and simple operation, does not depend on subjective judgment of the human eye, and can objectively provide high-precision data.
