Abstract
Description
Technical Field
[0001] This utility model belongs to the field of firearm calibration technology, specifically relating to a firearm cold calibration tool. Background Technology
[0002] The basic idea of laser gun calibration is to utilize the good coherence and collimation properties of lasers, use the laser as the theoretical extension line of the gun barrel, generate intersecting laser points at the target position, convert the ballistic descent height, obtain the simulated bullet impact point of the weapon on the target, and then calculate the front sight adjustment amount through the bullet impact point deviation, thereby achieving bulletless gun calibration.
[0003] To calculate the trajectory descent height, we must first analyze the forces and motion of the bullet after it leaves the barrel. During the supersonic spiral flight, the bullet is mainly affected by air resistance, gravity, crosswind resistance, and Magnus force (the high-speed rotation of the bullet causes unequal air resistance on the left and right sides, causing the bullet to deviate from the barrel axis; right-hand rifling deflects to the right, and left-hand rifling deflects to the left). Air resistance gradually reduces the bullet's flight speed, gravity causes the bullet to fall vertically in a free fall, forming an arc trajectory, and crosswind resistance and Magnus force cause the bullet to deflect laterally. Gun calibration is usually performed at a distance of 100m, at which point air resistance does not directly affect the trajectory, and the Magnus force has a relatively small impact. Crosswind resistance is corrected by the shooter during live-fire shooting and is not considered in the gun calibration process, so the main consideration is the effect of gravity.
[0004] Although the technical principle of laser gun calibration is relatively simple, its implementation requires solving three problems:
[0005] 1. Ensure the laser and barrel are aligned and coaxial; 2. Balance the relationship between the life of the retaining ring and the wear of the rifling; 3. Overcome the effects of decreased brightness at low temperatures and difficulty in heat dissipation at high temperatures. Among these, ensuring the laser and barrel are aligned and coaxial is the most important core issue. In view of the above issues, a cold alignment tool for firearms is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a gun cold calibration tool that can be designed and adjusted for weapons of different calibers, enabling unloaded calibration and simulated firing for most light weapons.
[0007] The specific technical solution adopted by this utility model is as follows:
[0008] A gun cold-calibration tool includes a power control box, which contains an industrial battery pack and a working mode control module. The working mode control module has two input interfaces, one of which is connected to one end of a data cable and the other end of a data cable. The other end of the data cable is connected to a vibration sensor interface, and the other end of the data cable is connected to a front laser. The right end of the front laser is connected to the left end of a slender shaft tail cone.
[0009] The front laser includes a laser module, and a dimming lens is fixedly installed at the left end of the laser module. The laser module interface is plugged into one end of a data cable.
[0010] The laser module has four screw holes, which are threaded to four directional adjustment screws respectively.
[0011] The slender tail cone includes a tail cone with two protrusions. The left end of the tail cone is fixedly connected to the right end of the laser module. The tail cone shaft is 200mm long and 5.7mm in diameter. The tail cone is made of beryllium copper and the material hardness is tempered to 41-43 HRC.
[0012] Each of the protrusions consists of a hollow hole and a slot with multiple through holes. Two retaining springs are fixedly installed inside each of the protrusions. The diameter of the protrusion is 6.0 mm and the length of the protrusion is not less than 60 mm.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0023] like Figure 1-3 As shown, a gun cold-calibration tool includes a power control box 1. An industrial battery pack and a working mode control module are fixedly installed inside the power control box 1. The working mode control module is provided with two input interfaces 13. The two input interfaces 13 are respectively plugged into one end of data cable 2 and data cable 7. The other end of data cable 2 is plugged into the interface of vibration sensor 3. The other end of data cable 7 is connected to the front laser 5. The right end of the front laser 5 is connected to the left end of the slender shaft tail cone 6.
[0024] Furthermore, the front laser 5 includes a laser module 53, with a dimming lens 51 fixedly installed at the left end of the laser module 53, and the interface of the laser module 53 is plugged into one end of the data cable 7.
[0025] Furthermore, the laser module 53 is provided with four screw holes, and the four screw holes are respectively threaded to four directional adjustment screws 52.
[0026] Furthermore, the slender tail cone 6 includes a tail cone 61, on which two protrusions 62 are provided. The left end of the tail cone 61 is fixedly connected to the right end of the laser module 53. The tail cone 61 has a shaft length of 200mm and a diameter of 5.7mm (slightly smaller than the barrel inner diameter of 5.8mm). The tail cone 61 is made of beryllium copper, and the material hardness is tempered to 41-43HRC, which ensures support without damaging the rifling.
[0027] Furthermore, each protrusion 62 consists of a hollow hole and a slot with multiple through holes. Two retaining rings 63 are fixedly installed inside each protrusion 62. The protrusion 62 is processed in one piece by drilling and wire cutting. The reasonable elasticity obtained by the one-piece processing improves the adaptability to the barrel with different wear levels, improves accuracy and extends service life. The double retaining rings effectively ensure the coaxiality of the aiming device's tail cone and the barrel. The diameter of the protrusion 62 is 6.0mm (slightly larger than the diameter of the barrel's serrations, 5.8-5.84mm) and the length of the protrusion 62 is not less than 60mm. The distance between two adjacent rifling grooves is approximately 240 / 4 = 60mm. To prevent the retaining rings 63 from falling into the rifling grooves, the length of the protrusion 62 is not less than 60mm.
[0028] Furthermore, the working mode control module is electrically connected to the industrial battery pack, and the working mode control module is also equipped with a charging port 8, a power switch 9, a working mode selection switch 10, a sensitivity adjustment hole 11, and a working indicator light 12.
[0029] Furthermore, the left end of the vibration sensor 3 is fixedly connected to the right end of the screw 4.
[0030] The working principle of this utility model is as follows: When using this device, the vibration sensor 3, the laser module 53 and the input interface 13 on the working mode control module can be connected by data cable 12 and data cable 27. The vibration sensor 3 is connected and fixed to the gun body by the screw 4. Then, the right end of the tail cone 61 is inserted into the gun barrel. When the right protrusion 62 contacts the gun barrel opening, the retaining spring 63 is squeezed. After the tail cone 61 is inserted into the gun barrel, the elasticity of the retaining spring 63 makes the outer side of the protrusion 62 fit tightly against the inner wall of the gun barrel. At this time, the front laser 5 can be used for calibration.
[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
