Technical Field

[0001] The invention belongs to the technical field of laser cleaning, and in particular relates to a portable pulse laser rust removal gun. Background Art

[0002] In today's industrial production and equipment maintenance, rust treatment of metal surfaces has always been a vital task. With the continuous advancement of science and technology, laser rust removal technology has gradually emerged among many rust removal methods due to its significant advantages such as high efficiency, environmental protection, and little damage to the substrate, and has been widely used.

[0003] At present, the common portable laser rust removal guns on the market have exposed many problems during actual use. Most existing laser rust removal guns are only equipped with a single light-emitting part, which greatly limits their working range during rust removal operations. It is difficult to perform comprehensive and efficient rust removal on workpieces with complex structures or special shapes. For example, when facing metal parts with workpiece holes, grooves or corners, laser rust removal guns with a single light-emitting part often cannot accurately irradiate the laser to these hidden or difficult-to-reach areas, thereby greatly reducing the rust removal effect. Summary of the Invention

[0004] The present invention addresses the problem in the prior art that when dealing with metal parts with workpiece holes, grooves or corners, laser rust removal guns with a single light output point often cannot accurately irradiate these hidden or hard-to-reach areas with the laser, thereby greatly reducing the rust removal effect. The present invention proposes the following technical solutions:

[0011] The fixed-point rust removal structure includes: a blocking frame, a second focusing mirror, a second protective mirror, a second refraction mirror, a flip structure and an adjustment structure;

[0012] The flip structure includes a rotating disk and a driving rod, and the rotating disk drives the first refractor to deflect through the driving rod;

[0013] The laser beam refracted by the first refractor enters the second focusing mirror along the optical path of the blocking frame, and is focused and emitted from the housing through the second protective mirror;

[0014] The adjustment structure includes a movable plate and a gear, and the movable plate drives the angle of the second refractor to deflect through the gear;

[0015] The laser beam refracted by the first refractor enters the second focusing mirror along the optical path of the blocking frame, is focused, refracted by the second refractor, and then exits the housing along the second protective mirror.

[0016] As a preferred embodiment of the above technical solution, the rotating disk is welded to the driving rod, and the driving rod is composed of a round rod and a connecting block, wherein one end of the connecting block is clamped and connected to the top edge of the first refractor, and the round rod is rotatably connected to the inside of the outer shell, and the center line of the round rod serves as the fulcrum for the rotation of the driving rod. When the rotating disk rotates, the driving rod drives the first refractor to deflect at an angle within a range of one hundred and eighty degrees around its fulcrum.

[0017] As a preferred embodiment of the above technical solution, a T-shaped rod is welded on the end face of the rotating disk opposite to the driving rod, and a round tube is welded on the end face of the T-shaped rod close to the rotating disk. A sleeve disk is sleeved on the outer side of the rotating disk, and the sleeve disk is fixedly installed on the outer side of the outer shell. An arc-shaped groove is opened inside the sleeve disk, and the round tube is located inside the arc-shaped groove. The T-shaped rod drives the driving rod to rotate through the rotating disk, and the cooperation of the round tube and the arc-shaped groove limits the rotation range of the rotating disk to one hundred and eighty degrees.

[0018] As a preferred embodiment of the above technical solution, the blocking frame is internally rotatably connected to a limiting member, the gear is fixedly sleeved on the outside of the limiting member, connecting strips are symmetrically welded on the outside of the gear and the connecting strips are sleeved on the outside of the limiting member, the connecting strips are fixedly connected to the second refractor, and the second refractor rotates with the limiting member as a fulcrum through the connecting strip.

[0019] As a preferred embodiment of the above technical solution, an adjusting member is rotatably connected inside the blocking frame, and the adjusting member drives the gear to rotate through the movable plate. A convex strip is welded on the lifting strip at a position corresponding to the outer side of the gear, and the convex strip is engaged with the inner tooth groove of the gear.

[0020] As a preferred embodiment of the above technical solution, the interior of the lifting bar is connected to the screw rod via a threaded connection, and the screw rod is driven to rotate by a driving member, which is a micro servo motor, and its output shaft is connected to the screw rod via a coupling.

[0021] As a preferred embodiment of the above technical solution, the inner wall edge of the blocking frame is filled with light absorbing material.

[0022] As a preferred embodiment of the above technical solution, the first protective mirror and the second protective mirror are both double-layer structures, with the inner layer being high-purity quartz glass and the outer layer being diamond coating.

[0023] As a preferred embodiment of the above technical solution, two water channel connection ports are symmetrically embedded and installed on one end surface of the shell, and an air channel connection port is provided on one end surface of the shell at a position between the two water channel connection ports.

[0024] The beneficial effects of the present invention are:

[0025] (1) The direction of the laser beam can be changed so that the laser beam flows along the inside of the blocking frame. When flowing along the inside of the blocking frame, the vertical laser beam is converted into an inclined laser beam through the second refraction mirror. When the blocking frame enters the hole of the workpiece, the inclined laser beam removes rust from the edge of the hole of the workpiece, thereby increasing the area reached by the laser, improving the rust removal effect, and improving the rust removal effect in the processing of workpieces with complex morphology;

[0026] (2) The device supports rapid switching between large-area rust removal and small-scale fine rust removal. When working on a large area, the laser beam forms a diffuse light spot through the first refractor and other components, which can quickly cover the surface of the workpiece; after switching to fine mode, the light path is changed by rotating the first refractor, and a narrow beam light spot is output through the second focusing mirror and the second protective mirror, which can accurately process complex structural parts and greatly improve the rust removal efficiency in different scenarios;

[0027] (3) The angle of the second refraction mirror can be precisely adjusted so that the inclined laser beam can perform circular rust removal along the inner wall of the workpiece hole, achieving processing without dead angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] Example 1

[0039] The present invention provides a portable pulse laser rust removal gun, such as Figures 1 to 8 As shown, it includes: a shell 1, a laser emitter 2, a straightening mirror 3, a first refractor 4, a first focusing mirror 5, a first protective mirror 6 and a fixed-point rust removal structure. The shell 1 integrates the core optical components and drive system of the laser rust removal gun; the laser emitter 2 is connected to the end of the shell 1 for emitting a laser beam; the straightening mirror 3 is connected to the shell 1 for straightening the laser beam; the first refractor 4 is connected to the shell 1 for changing the angle of the laser beam; the first focusing mirror 5 is connected to the shell 1 and is located below the first refractor 4 for focusing the laser beam; the first protective mirror 6 is connected to the shell 1 and is located below the first focusing mirror 5; the fixed-point rust removal structure includes: a blocking frame 7, a second focusing mirror 8, a second protective mirror 9, a second refracting mirror 10, a second refracting mirror 11, a second refracting mirror 12, a second refracting mirror 13, a second refracting mirror 14, a second refracting mirror 15, a second refracting mirror 16, a second refracting mirror 17, a second refracting mirror 18, a second refracting mirror 19 ...9, a second refracting mirror 19, a second refracting mirror 19, a The projecting mirror 10 and the flipping structure and the adjusting structure; the flipping structure includes a rotating disk 1101 and a driving rod 1102, and the rotating disk 1101 drives the first refractor 4 to deflect the angle through the driving rod 1102; the laser beam refracted by the first refractor 4 enters the second focusing mirror 8 along the optical path channel of the blocking frame 7, and after focusing, it is emitted out of the housing 1 through the second protective mirror 9; the adjusting structure includes a movable plate 1206 and a gear 1207, and the movable plate 1206 drives the second refractor 10 to deflect the angle through the gear 1207; the laser beam refracted by the first refractor 4 enters the second focusing mirror 8 along the optical path channel of the blocking frame 7, and after focusing, it is refracted through the second refractor 10 and emitted out of the housing 1 along the second protective mirror 9.

[0040] In existing technologies, when dealing with metal parts with workpiece holes, grooves or corners, laser rust removal guns with a single light output point often cannot accurately irradiate these hidden or hard-to-reach areas with the laser, which greatly reduces the rust removal effect and cannot meet the strict requirements of thoroughness and comprehensiveness of rust removal in actual production.

[0041] To this end, a blocking frame 7, a second focusing mirror 8, a second protective mirror 9, a second refractive mirror 10, a flip structure and an adjustment structure are provided. Through this structure, the direction of the laser beam can be changed, so that the laser beam flows along the inside of the blocking frame 7. When flowing along the inside of the blocking frame 7, the vertical laser beam is converted into an inclined laser beam through the second refractive mirror 10. When the blocking frame 7 enters the workpiece hole, the inclined laser beam removes rust from the edge of the workpiece hole, thereby increasing the area reached by the laser, improving the rust removal effect, and improving the rust removal effect in the processing of workpieces with complex morphology.

[0042] When in use, the laser emitter 2 is connected to a power source and starts to operate. When the laser emitter 2 operates, the laser beam is emitted. At this time, the laser beam enters the first refraction mirror 4 along the straightening mirror 3 and is refracted. The refracted laser beam enters the first protective mirror 6 along the first focusing mirror 5 and is emitted to the outside of the workpiece along the first protective mirror 6, thereby performing large-scale rust removal on the outside of the workpiece.

[0043] When small-scale laser rust removal is required, the first refractor 4 is rotated by the action of the flip structure. After the first refractor 4 rotates, the laser beam moves upward. The laser beam refracted by the first refractor 4 enters the second focusing mirror 8 along the optical path of the blocking frame 7, and is emitted from the housing 1 along the second protective mirror 9 after being focused. At this time, by changing the light output path, the laser beam can remove rust on a small area of ​​the workpiece;

[0044] Since the laser beam along the inside of the blocking frame 7 is a straight line, the outer shell 1 needs to be tilted when the inner wall of the workpiece hole needs to be cleaned, thereby increasing the cleaning of the inner wall of the workpiece hole. To this end, the blocking frame 7 is first raised and lowered along the inside of the outer shell 1 through the adjustment structure, and then the angle of the second refraction mirror 10 is adjusted through the adjustment structure. At this time, the laser beam refracted by the first refraction mirror 4 enters the second focusing mirror 8 along the optical path channel of the blocking frame 7, and after being focused, it is refracted by the second refraction mirror 10 and emitted from the outer shell 1 along the second protective mirror 9. At this time, the laser beam moves obliquely along the inner wall of the workpiece hole, and the inclined laser beam is used to remove rust on the inner wall of the workpiece hole, thereby improving the rust removal effect on the inner wall of the workpiece hole. Through the above method, the following problems are solved: first, the inclination of the laser beam causes the upper and lower inclined surfaces of the hole to be different from the laser beam, resulting in deviations in the process of rust removal of the workpiece hole; second, due to the tilting of the outer shell 1, part of the laser beam cannot enter the inside of the hole due to the obstruction of the workpiece; third, holes that are too deep require personnel to flip the workpiece, so as to remove rust on both sides, resulting in low rust removal efficiency.

[0045] Specifically, a laser emitter 2 is mounted on one end of the housing 1 by screws, a straightening mirror 3 is mounted on one end of the inner wall of the housing 1 near the laser emitter 2, a first refractor 4 is rotatably connected to the middle of the housing 1, a driving rod 1102 is mounted on one end of the first refractor 4, and a rotating disk 1101 is connected to one end of the driving rod 1102, a first focusing mirror 5 is mounted on the bottom end of the first refractor 4 inside the housing 1, a first protective mirror 6 is mounted on the bottom end of the first focusing mirror 5 inside the housing 1, and a blocking frame 7 is vertically movably connected to the position above the first refractor 4 inside the housing 1 , a second focusing mirror 8 is clamped and installed inside the blocking frame 7, a second protective mirror 9 is clamped and installed above the second focusing mirror 8 inside the blocking frame 7, a second refractive mirror 10 is movably connected between the opposite surfaces of the second focusing mirror 8 and the second protective mirror 9 inside the blocking frame 7, a movable plate 1206 is vertically movably connected inside the blocking frame 7, and a gear 1207 is meshed and connected to the outer side of the movable plate 1206, the first protective mirror 6 and the second protective mirror 9 are both double-layer structures, the inner layer is high-purity quartz glass, and the outer layer is diamond-coated, which is used to improve the wear resistance and anti-pollution ability of the lens;

[0046] Among them, the rotating disk 1101 is welded to the driving rod 1102, and the driving rod 1102 is composed of a round rod and a connecting block, wherein one end of the connecting block is clamped and connected to the top edge of the first refractor 4, and the round rod is rotatably connected to the inside of the shell 1. The center line of the round rod serves as the fulcrum for the rotation of the driving rod 1102. When the rotating disk 1101 rotates, the driving rod 1102 drives the first refractor 4 to deflect within an angle within a range of one hundred and eighty degrees around its fulcrum. In this way, the angle of the first refractor 4 can be adjusted, thereby changing the angle between the first refractor 4 and the ground, and at this time, the angle of refraction of the laser beam is changed.

[0047] Since the above process requires changing the angle of the laser beam, at this time, under the action of the first protective mirror 6 and the second protective mirror 9, there are two laser beam emission outlets on the outside of the shell 1. In order to reduce the influence of external light sources on the laser beam inside the shell 1, protective covers are snap-fitted and installed at one end of the first protective mirror 6 and the second protective mirror 9 inside the shell 1 and the blocking frame 7. When in use, when the laser needs to be emitted along one of the emission outlets of the first protective mirror 6 and the second protective mirror 9, the corresponding protective cover can be taken away. In addition, the inner wall edge of the blocking frame 7 is filled with light-absorbing material to absorb laser scattering energy and prevent stray light from interfering with the rust removal operation.

[0048] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, since the driving rod 1102 is driven to rotate by the rotating disk 1101, it is necessary to limit the rotation angle of the rotating disk 1101 to prevent the rotating disk 1101 from rotating too much or too little. For this purpose, a T-shaped rod 1103 is welded on the end surface of the rotating disk 1101 opposite to the driving rod 1102, and a round tube 1104 is welded on the end surface of the T-shaped rod 1103 close to the rotating disk 1101. A sleeve 1105 is sleeved on the outside of the rotating disk 1101. The sleeve 1105 is fixedly installed on the outside of the shell 1, and an arc groove is opened inside the sleeve 1105 ( Figure 5 ), the circular tube 1104 is located inside the arc-shaped groove, and the T-shaped rod 1103 drives the driving rod 1102 to rotate through the rotating disk 1101, and through the cooperation of the circular tube 1104 and the arc-shaped groove, the rotation range of the rotating disk 1101 is limited to one hundred and eighty degrees.

[0049] During use, the staff drives the rotating disk 1101 to rotate through the T-bar 1103, and the rotating disk 1101 drives the driving rod 1102 to rotate when it rotates. At this time, the T-bar 1103 drives the circular tube 1104 to move inside the arc groove when it rotates. When the circular tube 1104 moves to a position that fits the inner wall of the arc groove, the circular tube 1104 is limited so that the circular tube 1104 cannot continue to deflect, thereby limiting the T-bar 1103. For this purpose, the T-bar 1103 is limited by the circular tube 1104, and at this time, the T-bar 1103 limits the rotating disk 1101, thereby limiting the rotation range of the rotating disk 1101.

[0050] Since the rotation range of the rotating disk 1101 is limited in the above process, the rotating disk 1101 needs to be fixed after rotation to prevent the rotating disk 1101 from resetting after rotation. For this purpose, a telescopic member 1106 is symmetrically embedded and installed inside the rotating disk 1101. The movable end of the telescopic member 1106 is clamped and installed with an extrusion strip 1107. The extrusion strip 1107 is arc-shaped near the outer side of the sleeve 1105. The sleeve 1105 is provided with a placement groove ( Figure 5 ), due to the tension of the telescopic member 1106, the extrusion bar 1107 is driven to enter the placement groove of the sleeve 1105. At this time, the sleeve 1105 and the rotating disk 1101 are limited by the extrusion bar 1107 and the telescopic member 1106. The outer side of the rotating disk 1101 is symmetrically provided with a rectangular groove ( Figure 5 ), the telescopic member 1106 and the extrusion strip 1107 are located inside the rectangular groove.

[0051] During use, when the rotating disk 1101 rotates, the telescopic part 1106 drives the extrusion bar 1107 to move inside the placement groove of the sleeve disk 1105. At this time, the extrusion bar 1107 moves from the placement groove to the inner wall of the sleeve disk 1105. The extrusion bar 1107 squeezes the telescopic part 1106 through the obstruction of the sleeve disk 1105, causing the telescopic part 1106 to be compressed and enter the rotating disk 1101. At this time, the reset ability of the telescopic part 1106 drives the extrusion bar 1107 to enter the inner wall of the sleeve disk 1105. When the extrusion bar 1107 enters the placement groove of the sleeve disk 1105 again, the reset ability of the telescopic part 1106 drives the extrusion bar 1107 to enter the placement groove and squeeze and fit with it. At this time, the rotating disk 1101 and the sleeve disk 1105 are limited by the extrusion bar 1107 and the telescopic part 1106.

[0052] In the present application, the telescopic member 1106 is a linear motion structure, specifically a spring telescopic rod.

[0053] like Figures 6 to 8 As shown, since the blocking frame 7 limits the width of the laser beam, the laser beam can remove rust in a small range. However, in order to facilitate the laser beam to enter the inside of the workpiece hole and remove rust inside the workpiece hole, it is necessary to adjust the position of the blocking frame 7 so that the blocking frame 7 can enter the inside of the workpiece hole. To this end, lifting bars 1203 are symmetrically welded on the outside of the blocking frame 7. The inside of the lifting bar 1203 is connected with a screw rod 1202 through a thread. A limiting groove is provided inside the housing 1 at a position corresponding to the outside of the lifting bar 1203. The bottom end of the screw rod 1202 is connected to the output end of the driving member 1201 through a coupling. The driving member 1201 is fixedly installed inside the housing 1.

[0054] In the present application, the driving member 1201 is a structure for driving an object to rotate, specifically a micro servo motor.

[0055] During use, the driving member 1201 is connected to the power supply and starts to run. When the driving member 1201 runs, it drives the screw rod 1202 to rotate. When the screw rod 1202 rotates, it drives the lifting bar 1203 to rise along the inside of the limit groove, and at this time drives the blocking frame 7 to rise, so that the blocking frame 7 moves outward along the inside of the shell 1, thereby being exposed to the external environment. Since the blocking frame 7 exposed to the outside world is smaller than the overall volume of the shell 1, it is convenient to insert the blocking frame 7 into the workpiece hole of the workpiece, and further facilitates the rust removal work on the edge of the inner wall of the workpiece hole.

[0056] Since the above-mentioned gear 1207 requires a fulcrum during rotation, and a driving structure is required when the movable plate 1206 moves, so that the deflection structure can operate normally, at this time, the interior of the blocking frame 7 is rotatably connected to the limit member 1208 through the shaft sleeve, and the gear 1207 is fixedly sleeved on the outside of the limit member 1208. Connecting strips 1209 are symmetrically welded on the outside of the gear 1207 and the connecting strips 1209 are sleeved on the outside of the limit member 1208. The connecting strip 1209 is fixedly connected to the second refractor 10, and the second refractor 10 rotates with the limit member 1208 as the fulcrum through the connecting strip 1209. The interior of the blocking frame 7 is rotatably connected to the adjusting member 1205 through the bearing, and the adjusting member 1205 drives the gear 1207 to rotate through the movable plate 1206. The lifting strip 1203 is welded with a convex strip at the position outside the gear 1207, and the convex strip is engaged with the internal tooth groove of the gear 1207.

[0057] When in use, the staff rotates the adjusting member 1205, and the adjusting member 1205 rotates to drive the movable plate 1206 to slide inside the blocking frame 7 ( Figure 7 and Figure 8 As shown), when the movable plate 1206 moves, it engages with the gear 1207 and drives the gear 1207 to rotate. When the gear 1207 rotates, it drives the limit member 1208 to rotate inside the blocking frame 7, and at the same time drives the second refractor 10 to deflect through the connecting bar 1209, thereby changing the angle of the second refractor 10.

[0058] In the above process, it is necessary to rotate the adjusting member 1205. For this purpose, a disc is clamped and installed on the outside of the adjusting member 1205. The outside of the disc is provided with anti-slip grooves. The anti-slip grooves make it easier for people to drive the disc to rotate. At this time, the disc drives the adjusting member 1205 to rotate, which changes the difficulty of rotating the adjusting member 1205.

[0059] like Figure 1 and Figure 2As shown, since the laser emitter 2 generates a large amount of heat during operation, heat dissipation is required. For this purpose, two water channel connection ports are symmetrically embedded and installed on one end surface of the shell 1, and an air channel connection port is provided at a position between the two water channel connection ports on one end surface of the shell 1. At this time, the external water pipe and air pipe are respectively connected to the connection ports. At this time, the external water and gas enter the interior of the shell 1, and heat is exchanged inside the shell 1, thereby reducing the heat generated by the internal components of the shell 1 during operation.

[0060] Working principle: During actual use of the device, the circuit is connected, and the external water pipe and air pipe are respectively connected to the connection port (the water connection port and the air connection port belong to the existing technology and will not be elaborated on here). After water and ventilation, the circulating medium passes through the heat dissipation channel inside the shell 1, which can effectively take away the heat generated by the operation of the components. Then the protective cover at the bottom of the first protective mirror 6 is taken away. At this time, the laser transmitter 2 is connected to the power supply and starts to run. When the laser transmitter 2 is running, the laser beam enters the first refraction mirror 4 along the straightening mirror 3 for refraction. The refracted laser beam enters the first protective mirror 6 along the first focusing mirror 5 and is emitted to the outside of the workpiece along the first protective mirror 6, thereby performing large-scale rust removal on the outside of the workpiece.

[0061] When small-scale cleaning and rust removal is required, the protective cover at the bottom of the first protective mirror 6 is closed, and the protective cover at the top of the second protective mirror 9 is removed. Then, the staff drives the rotating disk 1101 to rotate through the T-shaped rod 1103. When the rotating disk 1101 rotates, it drives the driving rod 1102 to rotate. When the driving rod 1102 rotates, it drives the first refraction mirror 4 to deflect.

[0062] At this time, when the T-shaped rod 1103 rotates, it drives the circular tube 1104 to move inside the arc groove. When the circular tube 1104 moves to a position that is in contact with the inner wall of the arc groove, the circular tube 1104 is limited, so that the circular tube 1104 cannot continue to deflect, thereby limiting the position of the T-shaped rod 1103. To this end, the rotating disk 1101 is limited by the T-shaped rod 1103, so that the rotation range of the rotating disk 1101 is limited;

[0063] At the same time, when the rotating disk 1101 rotates, the extrusion strip 1107 is driven by the telescopic member 1106 to move from the central area to the edge of the placement groove of the sleeve disk 1105. At this time, the extrusion strip 1107 is completely moved out of the placement groove and enters the inner wall of the sleeve disk 1105 and fits into the inner wall of the sleeve disk 1105. The extrusion strip 1107 is squeezed by the telescopic member 1106 through the obstruction of the inner wall of the sleeve disk 1105, causing the telescopic member 1106 to be compressed, and the extrusion strip 1107 to enter the rectangular groove of the rotating disk 1101. At the same time, the extrusion strip 1107 enters the inner wall of the sleeve disk 1105, and the rotating disk 1101 is rotated again. When the rotating disk 1101 and the sleeve 1105 are in motion, the extrusion bar 1107 enters the corresponding position of the placement groove of the sleeve 1105 again. At this time, the resetting ability of the telescopic member 1106 drives the extrusion bar 1107 to enter the placement groove, so that the extrusion bar 1107 is squeezed and fixed along the placement groove and the sleeve 1105, so that the rotation disk 1101 and the sleeve 1105 are limited by the extrusion bar 1107 and the telescopic member 1106. At this time, the first refractor 4 rotates 180 degrees. Therefore, the laser beam refracted by the first refractor 4 enters the second focusing mirror 8 along the optical path of the blocking frame 7, and is emitted from the housing 1 through the second protective mirror 9 after being focused.

[0064] When the blocking frame 7 needs to go deeper into the hole of the workpiece, the driving member 1201 starts to run. When the driving member 1201 runs, it drives the screw rod 1202 to rotate. When the screw rod 1202 rotates, it drives the lifting bar 1203 to rise along the inside of the limiting groove. At this time, it drives the lifting bar 1203 to rise, so that the blocking frame 7 moves outward along the inside of the shell 1, thereby exposing it to the external environment. Then the person rotates the adjusting member 1205. When the adjusting member 1205 rotates, it drives the movable plate 1206 to slide inside the blocking frame 7. When the movable plate 1206 moves, it engages with the gear 1207 and drives the gear 1207. When the gear 1207 rotates, it drives the limiter 1208 to rotate inside the blocking frame 7, and at the same time drives the second refractor 10 to deflect through the connecting bar 1209. At this time, the angle of the second refractor 10 is changed. At this time, the laser beam refracted by the first refractor 4 enters the second focusing mirror 8 along the optical path of the blocking frame 7, and after being focused, it is refracted by the second refractor 10 and then emitted from the housing 1 along the second protective mirror 9. Then the blocking frame 7 is inserted into the hole of the workpiece. At this time, the inclined laser beam cleans vertically along the inner wall of the hole of the workpiece, and then the housing 1 is rotated to form a rotary cleaning.
