Description

Technical Field

[0001] The present invention relates to a camera-type laser collimation mirror, belonging to the technical field of calibration equipment. Background Art

[0002] The collimation mirror is an important instrument tool for fighter jets during production assembly, adjustment and testing. It can indicate the axes of the fighter jet fuselage, avionics equipment, aircraft guns, etc. By installing and adjusting the positions of various equipment through positioning jigs, it ensures the installation and positioning accuracy of position dimensions such as coaxiality and parallelism, which is an important indicator to ensure the performance of fighter jets. With the development of aviation technology, the improvement of equipment performance, and the progress of production technology, higher requirements are put forward for the accuracy and usage efficiency of the collimation mirror. The traditional collimation mirror is an optical collimation mirror, which uses the sight axis as the positioning axis. It mainly locates by observing the crosshair in the telescope through the eyepiece and connects the plug rod with the positioning hole of the equipment to be installed. There is usually an angle of about 1' between the sight axis of the optical collimation mirror and the axis of the plug rod, and the coaxiality is poor. During use, the focal length needs to be adjusted, which will affect the accuracy. Moreover, only one person can observe the pointing position of the object axis from the eyepiece at a time, with poor visibility and intuitiveness. Multiple people are required to cooperate during the work process, resulting in low efficiency. And when observing from different directions of the eyepiece, the pointing position will also change, with poor reliability. The main body of the plug rod is a metal smooth rod, and there is a certain gap between the plug rod and the positioning hole, and the coaxiality between the collimation mirror and the equipment to be installed is not good, affecting the positioning accuracy.

[0016] The following is combined with Figures 1-3 The present invention will be further described:

[0017] A camera-type laser collimation mirror, one end of the housing 3 is connected to an expansion plug 4, and several expansion openings 12 are provided on the surface of the expansion plug 4. One end of the expansion plug 4 is provided with a knob 7, and a screw rod 5 connected to the knob 7 extends into the expansion plug 4. The screw rod 5 is threadedly connected to a nut 6 fixed in the expansion plug 4. A limit block 11 is fixed at the end of the screw rod 5, and the limit block 11 is in contact with the limit surface in the expansion plug 4. The limit block 11 is frustum-shaped, and the side surface of the frustum is attached to and slidably connected to the limit surface. A universal adjustment seat 2 is provided in the housing 3. The universal adjustment seat 2 includes a fixed part 2.1, a deformable part 2.2, and an adjustment part 2.3 connected in sequence. The fixed part 2.1 is threadedly connected to the housing 3. The adjustment set screw is opposite to the adjustment part 2.3. A threaded hole 2.4 is provided at the end of the adjustment part 2.3. The fixing screw cooperates with the threaded hole 2.4 to fix the laser 1. The laser 1 is fixed at one end of the universal adjustment seat 2, and the other end of the universal adjustment seat 2 is fixed in the housing 3. Several adjustment set screws penetrate and are threadedly connected to the housing 3. The adjustment end of the adjustment set screw extends into the housing 3 and is arranged opposite to the universal adjustment seat 2. A micro camera 9 is fixed in the housing 3. The micro camera 9 is connected to a display by wire or wirelessly. An aviation socket 8 is provided on the housing 3, and the aviation socket 8 is connected to the micro camera 9. A dust cover 10 is provided at the end of the housing 3 to prevent dust from depositing on the surface of the laser or the camera lens.

[0018] The working process of the present invention:

[0019] The expansion plug 4 is used to connect to the positioning hole or pipe of the aircraft equipment. Insert the expansion plug 4 into the positioning hole or pipe, and rotate the knob 7. The nut 6 can be moved to the left relative to the screw rod 5, so that the distance between the nut 5 and the limit block 11 becomes smaller, squeezing the expansion plug 4. A number of expansion openings 12 are evenly provided on the wall of the expansion plug 4. After being squeezed, the outer wall of the expansion plug 4 deforms and expands, eliminating the fit clearance between the expansion plug 4 and the positioning hole or pipe, ensuring high coaxiality. Manually rotating the knob 7 can expand the plug, and the operation is simple. The universal adjustment seat 2 is a hollow cylinder. A number of strip holes are provided on the outer periphery of its deformable part 2.2. Elastic deformation can occur at this position under radial force. Press the adjustment set screw against the adjustment part 2.3 of the universal adjustment seat 2, and the deformable part 2.2 generates elastic deformation in the radial direction, so as to adjust the axis of the laser until it meets the requirements.

[0020] The laser 1 is a semiconductor laser, which emits a red visible light beam, which can intuitively indicate the axis of the equipment on the aircraft. The divergence angle of the laser beam is small and is approximately parallel light. The laser cross-section light spot is round, bright, clear and visible. The central light spot ≤5mm is convenient for visual high-precision calibration and alignment of aircraft installation, and the laser exit pupil power ≤50mW is harmless to the human body. The micro camera 9 can assist in observing and positioning the laser point position in a long-distance open field. It is equipped with a long-focus micro lens, and the field of view angle is small for easy positioning, and the observation distance can reach dozens of meters.

[0021] The laser collimation mirror utilizes the characteristics of light traveling in a straight line and the collimation of the laser beam, making the optical axis of the laser beam coaxial with the mechanical axis of the expansion plug 4. Furthermore, the expansion of the plug is coaxial with the height of the socket, and finally, the axis of the laser beam coincides with the mechanical axis of the device to be installed. For convenience of use, the display can be a handheld display, which is connected to the micro camera 9 to display the captured image, facilitating the user's observation.

[0022] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of the present technology, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
