Description

A calibration device for target mirror

technical field

The invention belongs to the field of measuring tools, and in particular relates to the field of calibration of helicopter target mirrors.

Background technique

At present, the calibration of the helicopter target mirror is to use the square box to clamp the target mirror on the V-shaped groove of the square box, fix the target mirror with a pressure plate, and then align the cross line in the target mirror with the target reticle cross line on the calibration table , to align the two crosshairs, turn the mirror tube 180° around the axis, and read the deviation a and b values in the horizontal and vertical directions, and calculate The value is the coaxiality of the target mirror.

content of the invention

Purpose of the invention:

During the detection process, align the crosshairs in the target mirror with the crosshairs on the target reticle. It is necessary to move the square box to adjust the distance or adjust the target repeatedly until the correct position is found. But the weight of the square box itself reaches about 15 kilograms, and it is very inconvenient to move the square box, and it is easy to cause danger. If the target is adjusted artificially, repeated measurements are required to find the correct position, which is time-consuming and labor-intensive. The newly developed calibration device can detect the helicopter target mirror conveniently and quickly, satisfy the accuracy of the helicopter target mirror in the calibration process, ensure the calibration accuracy, reduce labor intensity, and improve work efficiency.

Technical scheme of the present invention is:

Provide a target calibration mirror calibration device, including a main body 1 and an adjustment knob mechanism; the two ends of the main body are respectively extended to form a left sleeve 2 and a right sleeve 3, both sleeves are provided with a target calibration mirror positioning shaft fixing hole 4 , 5, for fixing the target mirror;

The adjustment knob mechanism includes a base on which two main body locking devices 12 are vertically extended, the main body is locked on the two main body locking devices, and the two main body locking devices are provided with At least two fastening knobs 14, so that the fastening top 13 of the fastening knobs touches the main body; rotating the fastening knobs can adjust the horizontal and/or vertical position of the main body relative to the base;

The base 11 is also provided with at least three level adjustment knobs 16 , the level adjustment knobs run through the base, and the top 15 of the level adjustment knobs is set downward, and the horizontal position of the base can be adjusted by rotating the level adjustment knobs.

Further, it also includes an external sleeve 6, one end of the external sleeve can be inserted into the left sleeve, and the other end has a fixing hole 7 for the positioning axis of the target mirror; and one end of the external sleeve has a screw hole 10, and the left sleeve There is a screw hole 9 on the barrel, and a locking screw 8 is screwed on the screw hole 9. The locking screw 8 passes through the screw hole 9 and the screw hole 10 to fix the external sleeve and the left sleeve as one.

Further, the two sleeves are provided with different diameters of fixing holes of the target mirror.

Further, the main body is a cylinder.

Further, the diameter of the fixing hole of the positioning axis of the target calibration mirror is Φ12.7mm, Φ23mm or Φ25mm.

Rotate the fastening knob on the main body locking device so that the fastening top contacts the main body, and fix the main body by contact force. Two main body left and right direction adjustment knobs are designed at the lower end of the circular main body locking device to adjust the target mirror and the target during calibration. The left and right positions can be quickly and accurately corrected. By rotating the adjusting knob, the screw moves against the main body, thereby adjusting the left and right positions of the target mirror and the target. Three adjustment knobs are designed on the base, which are used to quickly adjust the coincidence of the reticle in the target mirror and the target reticle. Adjust the top of the screw by rotating the pitch adjustment knob to achieve the purpose of adjustment.

Technical effect:

(1) The invented target mirror calibration device has the advantages of simple structure, convenient operation, good safety, low cost, good stability, and can ensure the accuracy during calibration.

(2) There is no special fixture for the calibration of the pre-invention target mirror, and the square box and V-shaped iron are used for clamping. It is very inconvenient to adjust the distance during the calibration process, and it is easy to cause safety accidents. It takes a long time to adjust during calibration, which increases the human error during calibration and affects the calibration accuracy. However, the utility model target mirror calibration device of the present invention is simple in structure, convenient and safe to use, and solves a large number of errors caused by man through the structure.

(3) The use of this target calibration device reduces the work intensity and improves work efficiency. In the past, it took 5 hours to calibrate a target target, and it was not possible to obtain particularly accurate data, and the calibration accuracy was not high. However, it only takes one hour to calibrate the coaxiality correcting mirror device of the utility model, the efficiency is increased by 4 times, and the calibration accuracy is guaranteed under the condition of ensuring the efficiency.

(4) This new type of target mirror calibration device fully meets the calibration accuracy requirements.

detailed description

The present invention will be described in further detail below. See Figures 1-4 below.

Choose a target calibration mirror with a model of Φ23mm. Before calibration, first fix the main body part with two circular main body locking devices 12, so that the fastening top contacts the main body, fix the main body by contact force, then place the target calibration mirror in the calibration positioning hole 5, and adjust the left and right direction adjustment knobs to adjust the calibration. For fast and accurate alignment of the target mirror and the target, adjust the adjustment knob 18 so that the crosshairs in the target mirror are aimed at the target reticle crosshairs on the calibration platform, so that the two crosshairs are aligned. Turn the mirror tube 180° around the axis, read out the deviation a and b values in the horizontal and vertical directions, and calculate The value is the coaxiality of the target mirror.
