Description

Technical Field

[0001] The utility model belongs to the technical field of dust cleaning, and specifically relates to a laser cladding dust cleaning device. Background Technique

[0002] Laser cladding technology refers to coating a coating material on the surface of a workpiece in different filling ways. After laser irradiation, the powder is melted and cladded on the workpiece. Among them, some powders are on the surface of the workpiece to be processed. If these accumulated powders are not cleaned up, it is not conducive to subsequent detection and processing.

[0003] Chinese Patent with application number CN202120188413.2 discloses a laser cladding dust cleaning device, which includes a brush assembly for cleaning floating dust, unused powder and attachments on the surface of the workpiece. The position of the brush assembly is adjustably arranged behind the cladding moving direction of the laser cladding device. The brush assembly includes a brush fixing member and a brush detachably arranged on the brush fixing member. The brush fixing member is connected to the laser cladding device. The brush is attached to the surface of the workpiece through the position adjustment of the brush assembly, and then the surface of the workpiece is cleaned by the cooperation of the brush and the rotation of the workpiece. After the laser cladded workpiece is cleaned, the state of the cladding layer can be visually observed, which is convenient for the quality inspector to timely detect the surface defects of the laser cladded workpiece and timely process the workpiece with surface defects, saving costs and improving the quality and accuracy of the laser cladded workpiece. When the above device is actually used, the residual dust on the surface of the workpiece is cleaned by the brush assembly, but the dust directly falls onto the lathe after being cleaned, and the staff still needs to clean the lathe later, which is rather troublesome and easily affects the subsequent processing of the workpiece. Moreover, the position of the brush assembly is adjusted through a corrugated pipe to adapt to workpieces of different sizes, which requires manual adjustment by the staff and is not convenient for the staff to use.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Detailed Description of the Specific Embodiments

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please refer to Figures 1-4 As shown, in this embodiment, a laser cladding dust cleaning device is provided, including a processing table 1. Two support frames 2 are installed on the top of the processing table 1. A guide rail 3 is installed on the tops of the two support frames 2. A laser cladding device 4 is slidably fitted on the periphery of the guide rail 3. A powder blowing assembly 18 is installed on one side of the laser cladding device 4. A workpiece 5 is rotatably fitted between the two support frames 2;

[0027] A fixed rod 6 is installed on one side of the laser cladding device 4. A moving rod 7 is elastically fitted inside the fixed rod 6. A brush 8 that cooperates with the workpiece 5 is installed at one end of the moving rod 7. A mounting assembly 9 that cooperates with the moving rod 7 is installed on the brush 8. A collection hopper 10 is installed at the bottom of the fixed rod 6. A collection box 11 is slidably fitted on the processing table 1. The collection hopper 10 is located below the workpiece 5, and the collection box 11 is located below the collection hopper 10.

[0028] One aspect of this embodiment is applied as follows: First, the workpiece 5 is installed between the two support frames 2. Then, the moving rod 7 will move by its own elastic force. The movement of the moving rod 7 drives the brush 8 to move, so that the brush 8 fits against the workpiece 5. When the workpiece 5 rotates, the brush 8 cleans the surface of the workpiece 5. The laser cladding device 4 can move along the guide rail 3. The movement of the laser cladding device 4 drives the fixed rod 6 to move. The movement of the fixed rod 6 drives the moving rod 7 and the brush 8 to move, so that the brush 8 cleans different positions of the workpiece 5. The dust falling during the cleaning process enters the collection hopper 10 and then enters the collection box 11 through the collection hopper 10. When the brush 8 needs to be replaced after long-term use, the installation component 9 is adjusted to release the fixation of the brush 8, the brush 8 is removed from the moving rod 7, and then the brush 8 is reinstalled. The brush 8 is fixed by the installation component 9.

[0029] By setting the moving rod 7, the moving rod 7 can move elastically, so that the moving rod 7 drives the brush 8 to fit against the surface of the workpiece 5, thus facilitating the brush 8 to adapt to workpieces of different sizes, reducing the situation where the staff manually adjusts the position of the brush 8, and being convenient for the staff to use. By setting the installation component 9, the installation component 9 can be adjusted to disassemble and install the brush 8. After the brush 8 is used for a long time, it can be replaced, which is convenient for replacing a new brush 8 for use and convenient for cleaning the surface of the workpiece. By setting the collection hopper 10, the collection hopper 10 can collect the dust cleaned by the brush 8, and the dust enters the collection box 11 through the collection hopper 10, thus facilitating the staff to collect and process the dust.

[0030] As Figure 4 shown, an installation groove 19 is opened at one end of the moving rod 7 of this embodiment. The installation component 9 includes an installation plate 901 installed on the brush 8, two pressing rods 902 elastically fitted in the installation plate 901, a clamping rod 903 installed at one end of the pressing rod 902, and two clamping grooves 904 respectively opened on both sides of the installation groove 19. One ends of the two pressing rods 902 respectively penetrate through both sides of the installation plate 901, and the two clamping rods 903 are respectively matched with the two clamping grooves 904. By setting the pressing rod 902, the pressing rod 902 can be adjusted to drive the clamping rod 903 to move, so that the clamping rod 903 moves out of the clamping groove 904, and then the brush 8 can be removed. When installing the brush 8, first adjust the pressing rod 902, then align the clamping rod 903 with the clamping groove 904. After releasing the pressing rod 902, the elastic force drives the pressing rod 902 to reset. The movement of the pressing rod 902 drives the clamping rod 903 to enter the clamping groove 904 to install the brush 8.

[0031] As Figure 2As shown in the figure, a chute is provided on the processing table 1 of this embodiment. The collection box 11 is slidably fitted in the chute. A handle 12 is installed on one side of the collection box 11, and a cover plate 13 is rotatably fitted on the top of the collection box 11. By providing the handle 12, the handle 12 can be pulled to drive the collection box 11 to move, and the collection box 11 can be removed from the processing table 1 to process the dust collected in the collection box 11. By providing the cover plate 13, the cover plate 13 can shield the collection box 11.

[0032] As Figures 2-3 shown in the figure, a through groove 14 is provided on the top of the cover plate 13 of this embodiment. A connecting pipe 15 is installed at the bottom of the collection hopper 10, and one end of the connecting pipe 15 is slidably fitted in the through groove 14. By providing the connecting pipe 15, the collection hopper 10 can collect the dust cleaned by the brush 8, and the dust in the collection hopper 10 can enter the collection box 11 through the connecting pipe 15.

[0033] As Figure 2 shown in the figure, chucks 16 and fixing elements 17 are rotatably fitted on the opposite sides of the two support frames 2 of this embodiment respectively, and the workpiece 5 is fitted with the chucks 16 and the fixing elements 17. By providing the chucks 16, the chucks 16 can clamp and fix one end of the workpiece 5, and the fixing elements 17 can squeeze the other end of the workpiece 5 to squeeze and fix the workpiece 5.

[0034] As Figure 3 shown in the figure, a limit block 20 is installed at the end of the moving rod 7 away from the brush 8 of this embodiment, and a spring 21 is installed between the limit block 20 and the fixed rod 6. By providing the spring 21, the spring 21 can drive the moving rod 7 to move, the moving rod 7 can drive the brush 8 to move, so that the brush 8 can fit the surfaces of workpieces of different sizes.
