Description

Technical Field

[0001] The utility model relates to the field of advanced manufacturing technology, in particular to a powder cleaning device for inner hole laser cladding equipment. Background Art

[0002] Inner hole laser cladding technology is an advanced surface engineering technology. It irradiates the surface of the inner hole of the metal with a high-energy laser beam, melts the material and forms a new cladding layer on the substrate, thereby repairing and strengthening the inner hole surface. When performing laser cladding processing, cladding materials are required to cooperate with the cladding processing. Cladding materials will produce powder when used. These powders adhere to the inner hole of the processed parts and will produce slag inclusions, pores, etc., so they need to be cleaned.

[0003] In the prior art, publication number: CN212770963U discloses a real-time cleaning device for waste powder in inner hole laser cladding, which includes an air compressor, a gas flow meter, a first hose, a second hose, an air inlet pipe, a powder sweeping seat and a powder sweeping nozzle. The gas flow meter is connected to the air compressor through the first hose and to the air inlet pipe through the second hose. The air inlet pipe is connected to the powder sweeping seat, and the powder sweeping nozzle is connected to the powder sweeping seat. The air inlet pipe and the powder sweeping nozzle are connected through the powder sweeping seat, and the powder sweeping seat is installed on the inner hole laser cladding device. The utility model, through the innovative design of the waste powder cleaning device, is the first to realize the automatic and real-time cleaning of accumulated waste powder without stopping the machine during the inner hole laser cladding process, thereby avoiding the adverse effects of waste powder on the laser cladding layer, and effectively solving a series of problems such as low production line efficiency, low degree of automation and unstable cladding quality caused by frequent shutdowns in the current inner hole laser cladding process. It has broad prospects for promotion and application.

[0004] However, the device still has problems. Compressed air with adjustable pressure and flow is used as power to clean the waste powder in the inner hole laser cladding process. The principle is to eject compressed air during the inner hole laser cladding process and blow the waste powder inside to the outside of the workpiece to complete the cleaning. However, in actual use, blowing the waste powder out of the workpiece by compressed air will cause waste powder splashing in the laser cladding area of ​​the workpiece. When waste powder splashes, it may cause the stability of the molten pool to be disturbed, resulting in defects such as cracks and pores in the cladding layer, thereby affecting the cladding quality. Therefore, we disclose a powder cleaning device for inner hole laser cladding equipment to meet people's needs. Utility Model Content

[0024] refer to Figure 1-Figure 2 Example 1 shown

[0025] A powder cleaning device for an inner hole laser cladding equipment comprises a laser cladding equipment body 1 and a collection box 2 mounted on one side thereof, an air inlet is opened on one side of the collection box 2, and an adsorption component is installed in the air inlet;

[0026] The adsorption component includes a waste powder pipe 3, which is fixedly installed in the air inlet, and a partition 5 is fixedly installed on the inner wall of the collection box 2. A connecting port is provided on one side of the partition 5, and one end of the waste powder pipe 3 is fixedly installed in the connecting port. An adsorption port is provided on one side of the collection box 2, and a filter screen 7 is fixedly installed in the adsorption port. An air inlet pipe 6 is fixedly installed on one side of the adsorption port, and an adsorption component for facilitating adsorption is fixedly installed on the other end of the waste powder pipe 3. The adsorption area of ​​the waste powder pipe 3 is close to the cladding area of ​​the laser cladding equipment body 1. The waste gas powder generated after the cladding is completed can be quickly adsorbed by the waste powder pipe 3. After the powder is sucked into the collection box 2 through the waste powder pipe 3, it is blocked by the filter screen 7 to stay and be collected in the collection box 2, avoiding the problem of powder contamination caused by direct discharge.

[0027] like Figure 2 As shown, a pressure valve 8 is fixedly installed at the other end of the air inlet pipe 6, an adjusting knob 9 is installed on the pressure valve 8, a pressure gauge 10 is installed on the pressure valve 8, and an external pipe 11 is fixedly installed at the exhaust end of the pressure valve 8. The pressure valve 8 is a prior art. When in use, the appropriate negative pressure value can be adjusted by rotating the adjusting knob 9 and coordinating with the display of the pressure gauge 10, so as to facilitate precise control of the adsorption process.

[0028] When in use, first you need to connect the external tube 11 to negative pressure air, and adjust the reference pressure gauge 10 to adjust the negative pressure value by adjusting the knob 9. After adjusting to the appropriate negative pressure value, extend the laser cladding equipment body 1 and the waste powder pipe 3 into the workpiece to work. During operation, the laser cladding equipment body 1 performs laser cladding, and at the same time, the collection box 2 is in a negative pressure state through the adsorption of the air inlet pipe 6, and the powder in the cladding process is adsorbed through the waste powder pipe 3 and the adsorption head 4. Compared with the direct blowing of compressed gas, the negative pressure adsorption avoids the disturbance of the stability of the molten pool caused by powder splashing, resulting in defects such as cracks and pores in the cladding layer, thereby improving the quality of the cladding.

A wind wheel 16 is fixedly installed on the surface of the driving shaft 15, a driving gear 17 is fixedly installed on one end of the driving shaft 15, and a transmission gear 18 is fixedly installed on one end of the transmission shaft 13. The driving gear 17 is engaged with the transmission gear 18. The wind wheel 16 is installed at a position below the inflection point of the adsorption head 4. When the adsorption head 4 is working, the negative pressure can make the wind wheel 16 rotate rapidly in one direction, thereby providing power for electrostatic adsorption of fluff.

[0032] The negative pressure state of the adsorption head 4 drives the wind wheel 16 to rotate, the wind wheel 16 drives the driving rod to rotate, the driving rod drives the driving gear 17 to rotate, the driving gear 17 drives the transmission gear 18 to rotate, the transmission gear 18 drives the transmission rod to rotate, and the transmission rod drives the electrostatic adsorption roller 14 to rotate, thereby electrostatically adsorbing and collecting some stubborn powders attached to the inner hole wall and adsorbing them through the adsorption head 4, thereby improving the cleaning effect.
