Description

Technical Field

[0001] This utility model relates to the field of laser melting repair technology, and in particular to a laser melting repair adsorption cladding head. Background Technology

[0002] Laser cladding technology, as an advanced material surface modification method, can melt specific materials and clad them onto the surface of a substrate under the action of a laser heat source, significantly improving the wear resistance, corrosion resistance, and heat resistance of the substrate. Taking the laser inner wall copper cladding project as an example, the project aims to use laser cladding to coat the inner wall of a specific component with a layer of copper, thereby improving the component's electrical and thermal conductivity, or enhancing its corrosion resistance in a specific environment.

[0003] Chinese patent CN221117615U discloses a laser melting repair adsorption cladding head. By rotating three dust suction heads in the dust suction mechanism around the axis of the cladding head body, it solves the problem that when existing laser melting repair cladding heads are used, metal powder that is not laser-fused onto the product is scattered into the air, causing environmental pollution and being inhaled by the human body, which affects health.

[0004] In the aforementioned patent document, one end of the suction tube is connected to the vacuum cleaner. When the suction mechanism absorbs metal powder, the absorbed metal powder may enter the vacuum cleaner through the suction tube, causing damage to the internal parts of the vacuum cleaner and thus affecting the use of the device. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: one end of the suction tube is connected to the vacuum cleaner. When the suction mechanism absorbs metal powder, the absorbed metal powder may enter the vacuum cleaner through the suction tube, which will cause damage to the internal parts of the vacuum cleaner and thus affect the use of the device. Therefore, a laser melting repair adsorption cladding head is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser melting repair adsorption cladding head includes a cladding head body. An annular mounting ring is fixedly installed at the lower end of the cladding head body. An annular cavity is formed inside the mounting ring. A dust suction pipe is installed on the side of the mounting ring. An annular hole communicating with the annular cavity is formed on the lower surface of the mounting ring. A rotating slip ring is slidably installed at the lower end of the mounting ring through a sliding component. Multiple rectangular plates are installed on the lower surface of the rotating slip ring. Adsorption cavities are formed inside the rectangular plates. The adsorption cavities are connected to the annular cavity through connecting holes. Multiple dust suction heads are installed on the opposite sides of the multiple rectangular plates. A drive component for driving the rotating slip ring to rotate is provided on the mounting ring.

[0008] A rectangular hole is provided on the back of the rectangular plate. A filter screen is installed at an angle in the adsorption chamber. One side of the filter screen is in contact with the upper end of the rectangular hole. A collection box is installed on the side of the rectangular plate by a magnetic suction assembly. A moving groove is provided on the side wall of the rectangular hole. A partition is installed in the moving groove by a reciprocating moving assembly. One side of the partition extends into the rectangular hole.

[0009] Preferably, the rectangular plate has a sliding hole on its side that communicates with the moving groove. The reciprocating moving assembly includes a slider that is slidably installed in the sliding hole and a reciprocating telescopic cylinder that is fixedly installed on the side of the rectangular plate. The output end of the reciprocating telescopic cylinder is fixedly connected to the slider, and the slider is fixedly connected to the partition plate.

[0010] Preferably, the magnetic suction assembly includes two magnets respectively fixedly installed on both sides of the collection box and two iron blocks respectively fixedly installed on both sides of the rectangular plate, and the magnets and iron blocks are magnetically connected.

[0011] Preferably, the sliding assembly includes a first support ring with an L-shaped longitudinal section fixedly installed on the lower surface of the mounting ring and a second support ring with an L-shaped longitudinal section fixedly installed on the lower surface of the mounting ring, wherein an annular slide is formed between the first support ring and the second support ring, and the rotating slip ring is slidably inserted into the slide.

[0012] Preferably, the rotating slip ring has multiple spherical grooves on both its outer and inner sides, and each of the multiple spherical grooves has rolling balls embedded in it.

[0014] The beneficial effects of this utility model are as follows:

[0015] After absorption, the metal powder enters the adsorption chamber through the suction head. The metal powder is filtered into the adsorption chamber by the filter screen. At the same time, through the cooperation of the rectangular holes, collection box, partition and reciprocating sliding components, the filtered metal powder is collected into the collection box, which can effectively prevent the absorbed metal powder from entering the vacuum cleaner and damaging the internal parts of the vacuum cleaner, and ensure the normal use of the device.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-7 A laser melting repair adsorption cladding head includes a cladding head body 1, an annular mounting ring 2 fixedly installed at the lower end of the cladding head body 1, an annular cavity opened inside the mounting ring 2, a dust suction pipe 3 installed on the side of the mounting ring 2, an annular hole communicating with the annular cavity opened on the lower surface of the mounting ring 2, a rotating slip ring 4 slidably installed at the lower end of the mounting ring 2 through a sliding component, a plurality of rectangular plates 5 installed on the lower surface of the rotating slip ring 4, an adsorption cavity opened inside the rectangular plate 5, the adsorption cavity communicating with the annular cavity through a connecting hole, a plurality of dust suction heads 6 installed on the opposite side of the plurality of rectangular plates 5, and a driving component for driving the rotating slip ring 4 to rotate on the mounting ring 2.

[0026] One end of the suction pipe 3 is connected to a vacuum cleaner, which is existing technology and is not shown in the figure. The vacuum cleaner and the suction pipe 3 are used to suction the inside of the mounting ring 2. The annular cavity of the mounting ring 2 is connected to the adsorption cavity of the rectangular plate 5 through a connecting hole. So when suction is performed on the inside of the mounting ring 2, the multiple suction heads 6 installed on the rectangular plate 5 will generate suction force to adsorb the metal powder that has not been laser-coated onto the product into the adsorption cavity.

[0027] The sliding assembly includes a first support ring 14 with an L-shaped longitudinal section, which is fixedly installed on the lower surface of the mounting ring 2, and a second support ring 15 with an L-shaped longitudinal section, which is also fixedly installed on the lower surface of the mounting ring 2. An annular slide is formed between the first support ring 14 and the second support ring 15. The rotating slip ring 4 is slidably inserted into the slide. Multiple spherical grooves are provided on both the outer and inner sides of the rotating slip ring 4. Rolling balls 16 are rolled and embedded in the multiple spherical grooves. The rotating slip ring 4 is rotatably installed at the lower end of the mounting ring 2 through the first support ring 14 and the second support ring 15. During the rotation of the rotating slip ring 4, the rolling balls 16 can reduce the friction between the rotating slip ring 4 and the first support ring 14 and the second support ring 15.

[0028] The drive assembly includes a rotating sleeve 17 fixedly mounted on the lower surface of the rotating slip ring 4, a gear ring 18 fixedly sleeved on the rotating sleeve 17, a drive motor 19 fixedly mounted on the side of the mounting ring 2 via a bracket, and a spur gear 20 fixedly mounted on the output shaft of the drive motor 19. The spur gear 20 is meshed with the gear ring 18.

[0029] During the laser cladding process, the drive motor 19 is started, which drives the spur gear 20 to rotate. The transmission between the spur gear 20 and the gear ring 18 drives the rotating slip ring 4 to rotate on the lower surface of the mounting ring 2 through the rotating sleeve 17. The rotating slip ring 4 drives multiple rectangular plates 5 to rotate around the central axis of the cladding head body 1, thereby achieving a better dust collection effect.

[0030] A rectangular hole is provided on the back of the rectangular plate 5. A filter screen 7 is installed at an angle inside the adsorption chamber. One side of the filter screen 7 is in contact with the upper end of the rectangular hole. A collection box 8 is installed on the side of the rectangular plate 5 through a magnetic suction assembly. A moving groove is provided on the side wall of the rectangular hole. A partition 9 is installed in the moving groove through a reciprocating moving assembly. One side of the partition 9 extends into the rectangular hole.

[0031] The filter screen 7 is installed at an angle inside the adsorption chamber, located on one side of the rectangular hole. When metal powder is absorbed into the adsorption chamber, the filter screen 7 intercepts the metal powder within the chamber and adheres to it, preventing the metal powder from entering the mounting ring 2 through the connecting hole. Simultaneously, the angled installation of the filter screen 7 causes the filtered metal powder to tend to move towards the rectangular hole. The reciprocating component drives the partition 9 to move back and forth within the rectangular hole. When the partition 9 blocks the rectangular hole, the metal powder remains between the filter screen 7 and the partition 9, preventing the metal powder collected in the collection box 8 from being sucked back into the adsorption chamber. When the partition 9 moves vertically downwards, the rectangular hole opens, allowing the metal powder to pass through and be collected in the collection box 8. The moment the rectangular hole opens, the metal powder passes through and enters the collection box 8, effectively preventing the collected metal powder from being sucked back into the adsorption chamber. This effectively prevents absorbed metal powder from entering the vacuum cleaner and damaging internal parts, ensuring the normal operation of the device.

[0032] The rectangular plate 5 has a sliding hole on its side that communicates with the moving groove. The reciprocating moving assembly includes a slider 10 that is slidably installed in the sliding hole and a reciprocating telescopic cylinder 11 that is fixedly installed on the side of the rectangular plate 5. The output end of the reciprocating telescopic cylinder 11 is fixedly connected to the slider 10. The slider 10 is fixedly connected to the partition plate 9. The output end of the reciprocating telescopic cylinder 11 can drive the slider 10 to slide up and down in the sliding hole, thereby driving the partition plate 9 to move up and down in the moving groove and the rectangular hole.

[0033] The magnetic assembly includes two magnets 12 fixedly installed on the two sides of the collection box 8 and two iron blocks 13 fixedly installed on the two sides of the rectangular plate 5. The magnets 12 and the iron blocks 13 are magnetically connected. The collection box 8 is installed on the rectangular plate 5 through the magnets 12 and the iron blocks 13, which facilitates the installation and disassembly of the collection box 8 and facilitates the subsequent processing of the absorbed metal powder.

[0034] In this invention, when metal powder is absorbed into the adsorption chamber, the filter screen 7 intercepts the metal powder within the chamber and adsorbs it onto the filter screen 7. This prevents the metal powder from entering the mounting ring 2 through the connecting hole. Simultaneously, the inclined filter screen 7 causes the filtered metal powder to tend to move towards the rectangular hole. The reciprocating component drives the partition 9 to reciprocate within the rectangular hole. When the partition 9 blocks the rectangular hole, the metal powder remains between the filter screen 7 and the partition 9, preventing the metal powder collected in the collection box 8 from being sucked back into the adsorption chamber. When the partition 9 moves vertically downwards, the rectangular hole opens, allowing the metal powder to pass through and be collected into the collection box 8. The moment the rectangular hole opens, the metal powder passes through and enters the collection box 8, effectively preventing the collected metal powder from being sucked back into the adsorption chamber. This effectively prevents the absorbed metal powder from entering the vacuum cleaner and damaging its internal parts, ensuring the normal operation of the device.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
