Description

Technical Field

[0001] The present invention relates to the technical field of gun barrel cleaning, and particularly to a lens mechanism for laser cleaning. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] After the gun barrel is used, residues will adhere to its inner wall. These residues will reduce the smoothness of the inner wall and increase the frictional resistance. Therefore, corresponding equipment is needed to clean its inner wall, and the inner wall of the gun barrel can be effectively decontaminated by laser cleaning. The existing laser cleaning equipment usually uses a single beam to clean the inner wall of the gun barrel. This method has the following disadvantages: it is difficult for traditional laser cleaning heads to synchronously cover the inner corners of the rifling, and the angle needs to be repeatedly adjusted, resulting in low efficiency. Moreover, after repeatedly adjusting the angle, there is a problem of general focusing accuracy. Therefore, a lens mechanism for laser cleaning is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a lens mechanism for laser cleaning to achieve precise and efficient laser cleaning of the inner wall of the gun barrel in view of the above deficiencies.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] Please refer to Figures 1-6 , the present invention discloses a lens mechanism for laser cleaning, including a rotating lens assembly 1, a mounting table 6, an air curtain assembly 7, and a blower 8. Among them, the rotating lens assembly 1 is rotatably mounted on the mounting table 6, a hollow motor is mounted on the mounting table 6, the air curtain assembly 7 surrounds the rotating lens assembly 1, and is communicated with the output end of the blower 8. When the blower 8 works, gas can be ejected from the air curtain assembly 7, and an air curtain is formed at the rotating lens assembly 1.

[0049] In one embodiment, it further includes two reflection components 2, which are rotatable and oppositely arranged on the rotating lens assembly 1. The rotating lens assembly 1 can be driven by the hollow motor to rotate, and when laser enters it, the rotating lens assembly 1 can divide the laser into two beams and reflect them to each reflection component 2. The reflection components 2 are arranged obliquely, and a focusing lens 25 is slidably arranged thereon. After the laser enters the reflection components 2, the reflection components 2 can cooperate with the focusing lens 25 to focus the laser and shoot it onto the inner wall of the gun barrel; the device further includes two focusing adjustment components 3 and a driving component 4. The focusing adjustment components 3 are used to adjust the focal length of each focusing lens 25, and the driving component 4 is used to drive the two reflection components 2 to rotate and swing.

[0050] The above-mentioned rotating lens assembly 1 includes a mounting shell 11, a beam splitter 12, and an intermediate mirror 13. The beam splitter 12 and the intermediate mirror 13 are mounted in the mounting shell 11. The rotation connection points of the two reflection components 2 with the rotating lens assembly 1 are staggered. During use, the laser will irradiate into the mounting shell 11, and when it passes through the beam splitter 12, it will be divided into two beams. One beam will directly enter one of the reflection components 2, and the other beam of laser will pass through the intermediate mirror 13 and be reflected into the other reflection component 2.

[0051] In specific implementation, the driving component 4 can drive the two reflecting components 2 to swing back and forth, so that the laser emitted from the reflecting component 2 and hitting the inner wall of the gun barrel can sweep the inner corners of the rifling. Cooperating with the hollow motor to drive the rotating lens assembly 1 to rotate, it can comprehensively and efficiently perform laser cleaning on the inner walls of the rifling of the gun barrel. Moreover, the focusing component 3 is used to adjust the focal length of each focusing lens 25, so that when the two reflecting components 2 at different rotating positions swing, the laser can be ensured to be focused on the inner wall of the gun barrel, thereby ensuring accurate and efficient laser cleaning.

[0052] In one embodiment, the reflecting component 2 includes a housing 21, a first reflecting mirror 23, and a second reflecting mirror 24. Among them, the housing 21 is rotatably installed on the mounting housing 11. A perforation 22 is provided on the housing 21, and the perforation 22 allows the laser to be reflected from the rotating lens assembly 1 into the housing 21. The focusing lens 25 is slidably installed in the housing 21.

[0053] In specific implementation, the first reflecting mirror 23 can reflect the laser to the second reflecting mirror 24 when the laser passes through, and the second reflecting mirror 24 can reflect the laser to the focusing lens 25 when the laser passes through.

[0054] In one embodiment, the focusing component 3 includes a telescopic rod 31, which is installed in the housing 21, and the telescopic end of the telescopic rod 31 is connected to the focusing lens 25. An inflation head 32 is installed on the telescopic rod 31 in a communicating manner, and the inflation end of the inflation head 32 is located outside the telescopic rod 31. The focusing component 3 further includes an air pump and a solenoid valve (not shown in the figure). The air pump is installed on the rotating lens assembly 1 and has two output ends. The input end of the solenoid valve is communicated with one output end of the air pump, and the other output end of the air pump and the output end of the solenoid valve are respectively communicated with the corresponding inflation heads 32.

[0055] In specific implementation, the number of the air pump and the solenoid valve can both be one. During use, the air pump is controlled to start, and it can supply air to the two telescopic rods 31, so that the telescopic ends of the two telescopic rods 31 perform telescopic adjustment, thereby driving the focusing lens 25 to slide in the housing 21 to change the distance between it and the second reflecting mirror 24, so as to complete the focusing work;

[0056] In addition, since the rotation connection points of the two reflecting components 2 and the rotating lens assembly 1 are staggered, when they are driven to swing by a driving component 4, their swing amplitudes are different. By controlling the flow rate of the gas passing through the solenoid valve, the amount of gas passing through the other output end of the air pump and the output end of the solenoid valve and entering each telescopic rod 31 is different. Such a design can adapt to the two reflecting components 2 with different swing amplitudes, so that the two beams of laser passing through the corresponding focusing lenses 25 can be effectively focused on the inner wall of the gun barrel.

[0057] In one embodiment, the driving assembly 4 includes a motor 41 which has two output ends and is disposed on the rotating lens assembly 1. First rotating shafts 42 are mounted on both output ends of the motor 41. The first rotating shafts 42 can be driven by the motor 41 to rotate. Second rotating shafts 43 are mounted on the ends of the first rotating shafts 42 away from the motor 41. Mounting caps 44 are rotatably mounted on the ends of the second rotating shafts 43 away from the first rotating shafts 42. Transmission rods 45 are mounted on the mounting caps 44. In addition, adjusting sleeves 46 are mounted on the reflection assemblies 2. The transmission rods 45 are slidably inserted into the adjusting sleeves 46. When the driving assembly 4 is working, it can drive the two reflection assemblies 2 to swing in opposite directions.

[0058] In specific implementation, when the motor 41 is started, it can drive the respective first rotating shafts 42 and second rotating shafts 43 to rotate, so that the mounting caps 44 swing in the eccentric direction of the first rotating shafts 42, and the swinging will drive the reflection assemblies 2 having the adjusting sleeves 46 to perform back-and-forth swinging adjustment.

[0059] In one embodiment, a heat dissipation plate 5 is further included. The heat dissipation plate 5 is mounted on the rotating lens assembly 1 for dissipating heat inside it. The motor 41 is disposed on the heat dissipation plate 5. An air curtain assembly 7 has an air outlet (not shown in the figure), and the air outlet faces the heat dissipation plate 5.

[0060] With such a design, the heat dissipation plate 5 can dissipate heat from the components inside the rotating lens assembly 1. Moreover, since the motor 41 is mounted on the heat dissipation plate 5, in cooperation with the air curtain assembly 7 and the blower 8, part of the air flow can be blown out from the air outlet, pass through the heat dissipation plate 5 and take away the heat, so as to facilitate dissipating heat from the motor 41 at the same time.

[0061] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0062] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0063] In addition, "a plurality of" means more than two.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
