Description

Technical Field

[0001] The utility model belongs to the technical field of optical equipment, and in particular relates to a detection device for horizontal deviation of a barrel axis. Background Art

[0002] The axis deviation of the equipment barrel refers to the phenomenon that the axis of the equipment barrel deviates from the original shooting plane at different elevation angles. Theoretically, when there is no deviation, when the equipment barrel is elevated at different angles, the axis of the barrel should be located in the plumb plane, and the deviation at different elevation angles should be 0. The smaller the deviation is in the actual shooting process, the higher the accuracy. At present, the measurement of axis deviation in the current GJB is completed by theodolite, quadrant, dial indicator, steel tape measure and artillery assembly parameter photoelectric detection system. Its measurement method is labor-intensive, time-consuming, and troublesome to calculate and measure. In addition, laser trackers, three-dimensional laser radars and other technologies are used to measure the two spatial straight line equations before and after the gun adjustment, convert them into projection surfaces for straight line equation solution, and thus obtain the deviation angle. However, this method has problems such as high detection technology requirements, high environmental requirements and poor economy. The current detection means cannot fully meet the current needs. Therefore, it is urgent to improve the in-situ detection capability and design a more economical, simpler and faster detection device for the horizontal deviation of the barrel axis.

[0019] In an embodiment of the present utility model, Figure 1 The following is a schematic diagram of a specific structure of a detection device for horizontal deviation of the barrel axis according to the utility model. Figure 1 As shown, the utility model specifically includes: a mounting shell 2, an objective lens 202, an image acquisition module 201, a barrel adapter component 1, a digital display and control component 3 and a target 4.

[0020] The objective lens 202 is vertically installed inside the mounting housing 2 and is located at the end of the mounting housing 2. The image acquisition module 201 is installed inside the mounting housing 2 and is located at the focus of the objective lens 202. Specifically, the center of the image acquisition module 201, the objective lens 202 and the barrel 6 of the equipment to be tested are on the same axis.

[0021] A barrel adapter assembly 1 is installed at one end of the mounting shell 1 away from the objective lens 202 . The mounting shell 1 is fixed to the barrel 6 of the equipment to be tested through the barrel adapter assembly 1 . The mounting shell 1 and the barrel 6 of the equipment to be tested are on the same axis.

[0022] like Figure 2 As shown, the target 4 is arranged in front of the objective lens 202 , and a vertical calibration line is arranged at the center of the target 4 .

[0023] The digital display and control component 3 is in communication connection with the image acquisition module 201, and the image acquisition module 201 can acquire the image of the target 4 through the objective lens 202. Specifically, the image acquisition module 201 is a CCD image sensor.

[0024] The digital display and control component 3 can generate a cross scale on the image, and calculate the horizontal offset angle of the gun barrel axis based on the image and the cross scale.

[0025] In one embodiment of the utility model, the digital display control component 3 includes a processor and a display screen, the processor is communicatively connected to the image acquisition module 103, and the display screen is communicatively connected to the processor. The processor is communicatively connected to the image acquisition module 103, and the display screen is communicatively connected to the processor; the processor can generate a cross scale on the image acquired by the image acquisition module 103, and display it through the display screen. Among them, the processor can be selected: Intel z8350. The digital display control component electronically divides the acquired image and generates a cross scale, which is similar to the target plate coordinates, and its center position can be adjusted, and the image size and brightness can be adjusted. Among them, the digital display control component electronically divides and displays the cross scale, which is a technology well known to those skilled in the art, so it will not be repeated here.

[0026] In one embodiment of the utility model, the barrel adapter assembly 1 includes a mechanical plug-in shaft. The mechanical plug-in shaft is inserted into the barrel 6 of the equipment to be tested, and the central axis of the device is adjusted to be consistent with the barrel 6 of the equipment to be tested. Specifically, the mechanical plug-in shaft is a conventional technical means in the field, so it will not be repeated here.

[0027] In one embodiment of the present invention, a laser emitter 5 is installed vertically upward at the bottom of the target 4, and the laser emitted by the laser emitter 5 is a vertical calibration line. It should be noted that the vertical calibration line can be generated by irradiation of the laser emitter, or by a plumb line or pattern. The target is located at a certain distance from the objective lens. , calibrate the verticality and place it in a fixed position to ensure that the target line is vertical.

[0028] The specific working process of the utility model is as follows:

[0029] The utility model uses the barrel adapter component 1, and the adapter end can be accurately and tightly positioned after being inserted into the barrel, so that the alignment positioning component and the axis of the equipment launch barrel are in a vertical plane. The target is placed far away from the objective lens and at a certain distance. The image acquisition module acquires the image of the distant acquisition target 4 through the objective lens. After the target 4 is imaged through the objective lens, it is converted into an optical signal by the image acquisition module and then transmitted to the digital display and control component. The processor of the digital display and control component processes the image and displays a cross scale on the image. The cross scale represents the crosshair of the barrel of the equipment to be tested. Figure 2 shown.

[0030] After the device is turned on, the target can be observed through the digital display and control component to detect the deviation angle of the gun axis. According to the formula ,in is the barrel axis offset angle, is the distance between the end face of the collimation and positioning assembly housing and the linear target, It is the horizontal distance between the center of the electronic reticle and the vertical target after the gun is adjusted. Point A is the deviation position of the cross-reticle center of the collimation and positioning component after the gun is adjusted. The distance is calculated by the processor of the digital display and control component. .

[0031] It should be noted that the above formulas are conventional technical formulas, and the coordinate extraction and image processing algorithms are also conventional technical means in this field, so they will not be repeated here.

[0032] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
