Description

Technical Field

[0001] This utility model relates to the field of borescopes, and in particular to borescopes for variable-focus artillery. Background Technology

[0002] Traditional inspection instruments have significant limitations during the inspection process, especially when observing side walls: their fixed focal length design cannot adapt to the varying curvature of side walls at different depths, resulting in the imaging plane not precisely aligning with the side wall structure and exhibiting obvious defocusing. This optical defect causes the observed image to appear blurry at the edges and lose details, which not only affects the accuracy of defect identification but may also obscure minute cracks or corrosion features, posing a potential hazard for equipment safety assessment. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a variable focus artillery boresight instrument, which can accurately and clearly observe the sidewalls of the bore at different depths through the focusing system, effectively avoiding the omission of minor defects.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a variable-focus artillery boresight device, including a main body and a variable-focus camera module;

[0005] The outer periphery of the main body is provided with several sets of support wheels.

[0006] The variable zoom camera module is located at the front of the main body;

[0007] The zoom camera module is connected to the control box via a wiring harness.

[0008] This design incorporates a support wheel assembly on the main body, which contacts the inner wall of the gun barrel, positioning the main body in the center of the barrel. This allows the zoom camera module to be located in the center of the barrel for inspection. Because of the zoom camera module, the focusing system enables precise and clear observation of the sidewalls of the barrel at different depths, effectively preventing the omission of minute defects. This provides more accurate information for the safety assessment of the gun barrel.

[0009] Preferably, the front end of the main body is rotatably fitted with an axially rotating base, which is driven by a first motor, and the variable-focus camera module is connected to the axially rotating base. The rotating base allows the variable-focus camera module to rotate circumferentially, making it easier to observe the condition of the surrounding gun barrel.

[0010] Preferably, the axial rotating base has base columns at its two front ends, and a radial rotating base is provided between the base columns. The radial rotating base is rotatably engaged with the base columns via a rotating shaft. The radial rotating base is driven by a second motor, and the variable zoom camera module is disposed on the radial rotating base.

[0011] It can enable the variable zoom camera module to swing relative to the axis, further improving its observable range.

[0012] Preferably, the radially rotating base is provided with a transparent rotating cover, and the zoom camera module is located inside the transparent rotating cover. This protects the zoom camera module.

[0013] Preferably, the main body is provided with a transparent protective cover, and the variable zoom camera module, radial rotation base, and axial rotation base are located inside the transparent protective cover. This can protect the variable zoom camera module and the mirror rotation structure.

[0014] Preferably, the same support wheel assembly includes a wheel frame and at least two rollers, the wheel frame being disposed on the main body, and the rollers being distributed back and forth along the axial direction. This can improve the axial stability of the main body.

[0015] Preferably, the support wheel assembly comprises five sets, which can provide more stable support.

[0016] Preferably, the rear end of the wheel frame is hinged to the rear end of the main body, and the front end of the main body is fitted with a sliding ring and a positioning ring. The sliding ring is connected to each of the wheel frames via a connecting rod, and the positioning ring is threaded onto the periphery of the main body. The positioning ring is positioned further away from the wheel frame than the sliding ring. A limiting platform is provided on the periphery of the front section of the main body, and a spring is provided between the sliding ring and the limiting platform. The spring pushes the sliding ring forward. By rotating the positioning ring, the sliding ring can be pushed backward, and the sliding ring pushes the front end of the wheel frame to swing outward, making the outer diameter formed by the rollers larger, which can be used in gun barrels with larger inner diameters.

[0017] Preferably, two positioning rings are arranged adjacent to each other, forming a self-locking structure.

[0018] The beneficial effects of this utility model are:

[0019] By using a focusing system to accurately and clearly observe the sidewalls of the gun barrel at different depths, it is possible to effectively avoid missing minor defects. Attached Figure Description

[0027] This design incorporates a support wheel assembly 4 on the main body 1. This assembly contacts the inner wall of the gun barrel, positioning the main body 1 in the center of the barrel. This allows the zoom camera module 12 to be located in the center of the barrel for inspection. Because of the zoom camera module 12, the focusing system enables precise and clear observation of the sidewalls of the barrel at different depths, effectively preventing the omission of minute defects. This provides more accurate information for the safety assessment of the gun barrel.

[0028] In this embodiment, the variable focus camera module 12 adopts an M12 precision focusing voice coil, which can achieve a fine adjustment accuracy of 0.05mm.

[0029] The front end of the main body 1 is rotatably fitted with an axially rotating base 7, which is driven by a first motor. The variable-focus camera module 12 is connected to the axially rotating base 7. The rotating base allows the variable-focus camera module 12 to rotate in a circumferential direction, making it easier to observe the condition of the surrounding gun barrel.

[0030] The axial rotating base 7 has base columns 8 on both front ends, and a radial rotating base 9 is provided between the base columns 8. The radial rotating base 9 is rotatably engaged with the base columns 8 through a rotating shaft. The radial rotating base 9 is driven by a second motor, and the variable zoom camera module 12 is disposed on the radial rotating base 9.

[0031] It can enable the zoom camera module 12 to swing relative to the axis, further improving its observable range.

[0032] The radial rotating base 9 is provided with a transparent rotating cover 10, and the variable zoom camera module 12 is located inside the transparent rotating cover 10. This can protect the variable zoom camera module 12.

[0033] The main body 1 is provided with a transparent protective cover 11, and the variable zoom camera module 12, the radial rotation base 9, and the axial rotation base 7 are located inside the transparent protective cover 11.

This can improve the axial stability of the main body 1.

[0036] The support wheel assembly 4 comprises five sets, providing more stable support.

[0037] Example 3

[0038] Compared to Example 2, combined with Figure 2 As shown, this embodiment also includes the following differences: the rear end of the wheel frame 2 is hinged to the rear end of the main body 1, and the front end of the main body 1 is fitted with a sliding ring 14 and a positioning ring 16. The sliding ring 14 is connected to each of the wheel frames 2 via a connecting rod 17. The positioning ring 16 is threaded onto the periphery of the main body 1. The positioning ring 16 is positioned further away from the wheel frame 2 than the sliding ring 14. A limiting platform 13 is provided on the periphery of the front section of the main body 1. A spring 15 is provided between the sliding ring 14 and the limiting platform 13, and the spring 15 pushes the sliding ring 14 forward. By rotating the positioning ring 16, the sliding ring 14 can be pushed backward, and the sliding ring 14 pushes the front end of the wheel frame 2 to swing outward, so that the outer diameter formed by each roller 3 is larger, which can be used for gun barrels with larger inner diameters.
