Description

Technical Field

[0001] The present invention relates to the field of laser cladding, and in particular to high-speed laser cladding equipment. Background Art

[0002] When performing surface processing on workpieces, laser cladding is also used. This method can be used to modify the surface of the workpiece, for example, to form surface features with wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties; and metal powder suitable for the workpiece can also be selected to repair surface defects of defective workpieces. However, there are currently many problems in the treatment of surface defects of cylindrical workpieces.

[0003] At present, cylindrical workpieces such as pistons, drive shafts, and connecting rods are easily affected by collisions with foreign objects or unavoidable mechanical collisions when in use. Local fatigue and stress release of cylindrical workpieces during operation may also cause surface defects. These surface defects are more likely to be local tissue defects such as pits and cracks. In order to reduce production and construction costs, such workpieces with surface defects are mostly repaired by laser cladding. The current laser cladding equipment uses an integral laser cladding method for the repair process of such workpieces, that is, the entire surface area of ​​the workpiece is laser clad. However, this method has the disadvantage of being time-consuming and consuming a lot of metal powder. The workpiece needs to be ground for a long time afterwards, resulting in a long process. Laser cladding will also be performed on other normal areas of the workpiece surface, resulting in normal areas on the workpiece surface. Over-processing will require the workpiece to be re-run in when it is subsequently installed and used, causing inconvenience during installation and use. There is also a method of manually locating the surface defects of the workpiece and then using the laser cladding equipment to perform laser cladding operations on the located surface defects. However, the current method still has the disadvantage of being time-consuming and requiring manual positioning of the workpiece surface. In addition, it is difficult to accurately locate the defective part manually, resulting in low accuracy. In addition, the current method requires the laser cladding equipment to be frequently turned on and off, which can easily lead to the existing laser cladding equipment performing laser cladding operations on the surface defects of the workpiece when the laser power is not stable and the powder output is uneven, resulting in uneven texture of the molten pool formed on the surface of the workpiece due to uneven heating, resulting in the workpiece cladding layer having different metallographic structure densities.

[0004] Therefore, it is necessary to develop a high-speed laser cladding equipment to solve the above problems. Summary of the Invention

[0042] Example 2, as Figures 1-14 As shown, the installation and adjustment of the high-speed laser cladding equipment are as follows: ① Installation: Install the drive base 1 of the high-speed laser cladding equipment on the ground base, and then assemble the cylindrical workpiece with surface defects to be processed between the two sets of chuck modules 2; then, according to the material of the workpiece, select the metal powder suitable for processing and connect it to the powder feeding pipeline module 93, and adjust the operating power of the high-speed laser generating module 92 according to the selected metal powder. ② Adjustment: According to the outer diameter of the workpiece assembled between the chuck modules 2, control the first electric track 83 to drive the cladding device 9 to move downward, so that the cladding device 9 can determine the appropriate processing height according to the outer diameter of the workpiece; and adjust the fourth electric track 111 to adjust the height of the sonar scanning probe 112 and the outer periphery of the workpiece.

[0043] The laser cladding process of the high-speed laser cladding equipment for workpiece surface defects is divided into two steps. The first step is to locate the defects on the workpiece surface and determine the defect position by scanning the mechanism. The second step is the laser cladding operation process of cladding the defects on the workpiece surface. The details of the defect location determination process and laser cladding operation process are as follows:

[0044] Determine the defect location process: ① Positioning: Control the transverse track pair 3 to operate, so that the transverse track pair 3 drives the displacement frame 4 and the mounting frame 5 to move stepwise to the right, so that the mounting frame 5 surrounds the required processing area on the workpiece surface; ② Scanning: Turn on the sonar scanning probe 112, and at the same time start the driving base 1 to drive the chuck module 2 to rotate clockwise, so that the workpiece rotates clockwise for one circle. The sonar scanning probe 112 will emit ultrasonic signals to the workpiece surface and receive echoes from the workpiece surface. It will automatically analyze and model the structure of the workpiece surface through the echo signals, and then determine whether there are defects such as pits and surface cracks on the workpiece surface. Judgment; ③ Data collation: Determine the position of the defect based on the angle of rotation of the workpiece driven by the driving base 1 and the lateral position of the lateral track pair 3, and transmit the position and defect structure of the defect to the CNC computer for controlling the operation of the driving device 8 and the cladding device 9; ④ Loop step: If the driving base 1 drives the workpiece to rotate one circle, and the sonar scanning probe 112 scans the surface of the workpiece and finds that there is no defect, then the lateral track pair 3 is controlled to step again, so that the sonar scanning probe 112 loops as in the above "determine the defect position ①-③ steps" to scan the surface of the workpiece in the next area for defects.

[0045] Laser cladding operation process: ① Positioning: After the driving base 1 drives the workpiece to rotate for one circle to complete the defect scanning and identify the defect, the driving base 1 is controlled to drive the workpiece to continue rotating so that the position with the defect on the workpiece rotates to the bottom of the cladding device 9; ② ​​Protection process: Control the third electric track 101 to drive the intercepting frame 102 to move to the rear side so that the heat-resistant tempered glass structure of the intercepting frame 102 is below the cladding nozzle port 94. At this time, the lower side opening of the intercepting frame 102 is above the collection chamber 103; ③ Processing of the initial stage of the cladding operation: Start the powder feeding pipeline module 93 and the external powder feeding mechanism and control valve 95 connected thereto, so that the initial stage of the metal powder is discharged to the intercepting frame 1 through the cladding nozzle port 94 02, and then slides down into the collecting chamber 103 through the inclined bottom structure of the intercepting frame 102. After the external powder feeding mechanism and the powder feeding pipeline module 93 discharge the powder evenly through the cladding nozzle port 94, the high-speed laser generating module 92 can be turned on to emit a high-energy laser at the heat-resistant tempered glass structure of the intercepting frame 102, so that the high-speed laser generating module 92 and the ejected powder melt at the heat-resistant tempered glass structure of the intercepting frame 102 to form a molten pool, and the molten pool does not adhere to the heat-resistant tempered glass structure of the intercepting frame 102. The formed molten pool will slide down into the collecting chamber 103 through the vibration of the equipment operation after hardening, so that the metal powder accumulated at the powder feeding pipeline module 93 of the cladding device 9 does not participate in the laser cladding. The process can be carried out by cladding the defects of the workpiece under the condition that the high-speed laser generating module 92 outputs stable power and the powder feeding pipeline module 93 feeds powder evenly, so as to avoid the uneven texture caused by the initial material of the cladding device 9 being directly clad on the surface defects of the workpiece, thereby ensuring the quality of the laser cladding operation on the surface defects of the workpiece; ④ Exit the protection process: after the output power of the high-speed laser generating module 92 is stable and the powder feeding pipeline module 93 feeds powder evenly, the third electric track 101 can be controlled to move forward to make the intercepting frame 102 exit the position below the cladding device 9 and the driving device 8; ⑤ Laser cladding of workpiece defects: when the intercepting frame 102 exits the position below the nozzle of the cladding end head to the front side, The high-speed laser generating module 92 outputs stable power and the powder feeding pipeline module 93 uniformly feeds powder to perform cladding operations on the workpiece defects. At this time, the electric arc track 81, the first electric track 83, and the second electric track 85 of the driving device 8 will operate in a coordinated manner. The coordinated operation mode is calculated based on the specific position and modeling structure of the workpiece defect obtained in the above-mentioned "step ③ of determining the defect position", so that the cladding device 9 can accurately perform laser cladding operations on the surface defects of the workpiece; ⑥ Stop the laser cladding operation: After the laser cladding of the defect is completed, the high-speed laser generating module 92, the control valve 95, the powder feeding pipeline module 93 and its external powder feeding mechanism are closed, so that the cladding device 9 stops the laser cladding operation;⑦Circulation process: if the scanning layer of the workpiece surface still has other defects, the base 1 is driven to rotate the workpiece, so that the next workpiece surface defect is rotated to the bottom of the cladding device 9, and the above-mentioned "⑤-⑥ steps of cladding operation for workpiece defect position and structure" are operated in a circulating manner; ⑧ Laser cladding of the next scanning layer: if the scanning layer of the workpiece surface has no other surface defects, the next layer of the workpiece surface is scanned for defects as described above in the "defect position determination" process, and the workpiece surface defects are laser cladded as described above in the "laser cladding operation for workpiece defect position and structure".

[0046] After the workpiece surface defects are positioned by the scanning device 11 and the defect structure is modeled, the laser cladding operation for the workpiece surface defects can be accurately and automatically performed, so that the workpiece surface has the characteristics of stable metallographic phase and dense structure after accurate laser cladding operation. The accurate laser cladding operation can make the laser cladding operation area not involve other areas of the workpiece surface, so that the irradiation of the high-speed laser generation module 92 does not cause surface heat melting and unnecessary processing of other areas of the workpiece surface, reducing the workload of subsequent cladding layer surface treatment such as turning, milling and polishing.

[0047] By moving the intercepting frame 102 to the bottom of the cladding device 9, discharging the residual accumulated primary metal powder in the intercepting frame 102 and the collection cabin 103 by the powder feeding pipe module 93 of the cladding device 9, opening the high-speed laser generation module 92 to perform primary cladding at the intercepting frame 102 after uniform powder output by the powder feeding pipe module 93, and then withdrawing the intercepting frame 102 to perform laser cladding on the workpiece surface defects, the accumulated metal powder at the powder feeding pipe module 93 does not participate in the laser cladding process, and the workpiece defects can be cladded with stable power output by the high-speed laser generation module 92 and uniform powder feeding by the powder feeding pipe module 93, avoiding the phenomenon of uneven texture caused by direct cladding of the primary material of the cladding device 9 on the workpiece surface defects, and ensuring the quality of the laser cladding operation of the workpiece surface defects.

[0048] Further, when the third electric track 101 is controlled to move the intercepting frame 102 to the rear side, as described above in the process of "laser cladding operation process ③", ① the first stage of recycling metal powder: the recycling channel 132 is located below the cladding nozzle port 94, the powder feeding pipe module 93 and the external powder feeding mechanism and control valve 95 connected thereto are started, the first stage of metal powder material is discharged into the recycling channel 132 through the cladding nozzle port 94, and the extraction pump 122 is started to recycle the first stage of metal powder material in the recycling channel 132 into the recycling tank 123, thereby saving materials ② recycling molten material: after the external powder feeding mechanism and the powder feeding pipe module 93 uniformly discharge powder through the cladding nozzle port 94, the third electric track 101 is controlled to move the recycling channel 132 to the front side, and the rear part of the intercepting frame 102 is still located below the cladding nozzle port 94, so that the high-speed laser generating module 92 emits high-energy laser at the intercepting frame 102, and the high-speed laser generating module 92 and the sprayed powder are fused at the heat-resistant tempered glass structure of the intercepting frame 102 to form a molten pool and fall into the collection cabin 103.

[0049] Further, in the process of "determining the position of the defect ②", if a defect is found on the surface of the workpiece at this scanning position, the laser impurity removal module 15 and the ultrasonic cleaning module 14 can also be started, and the process is as follows: ① ultrasonic dust removal: the ultrasonic cleaning module 14 controls the drive base 1 to rotate the workpiece one revolution according to the angle and position of the defect on the workpiece, outputs sound waves to the surface defect of the workpiece, removes the dirt and impurities in the defect structure of the workpiece, and increases the purity of the molten pool formed by the laser cladding when the workpiece defect structure is subjected to laser cladding operation. ② Laser impurity removal: the laser impurity removal module 15 controls the drive base 1 to rotate the workpiece one revolution according to the angle and position of the defect on the workpiece, outputs high-energy laser to the surface defect of the workpiece, removes the surface oxide layer and other metal compound impurities adhered to the workpiece defect, and increases the purity of the molten pool formed by the laser cladding in the workpiece surface defect when the workpiece surface defect is subjected to laser cladding operation. Avoiding impurities affecting the mixture of the molten pool formed by the laser cladding in the workpiece surface defect, so that the workpiece surface defect has consistent metallographic and metallic properties with the surrounding base after laser cladding operation.
