Description

Technical Field

[0001] The invention relates to a mandrel laser cladding device, belonging to the technical field of laser cladding equipment. Background Technology

[0002] Laser cladding is a surface modification technology that uses a laser beam to melt and deposit cladding material onto the surface of a workpiece, forming a dense and firmly bonded cladding layer. This improves the surface properties of the workpiece, such as wear resistance, corrosion resistance, and high-temperature resistance. In the field of mandrel processing, laser cladding is often required to extend the service life of mandrels and improve their surface hardness and wear resistance.

[0003] Existing laser cladding equipment for mandrels typically employs a three-jaw chuck in conjunction with a machine tool tip to clamp and rotate the mandrel. Simultaneously, a three-axis linear motion mechanism moves the laser cladding head to complete the cladding operation on the mandrel surface. However, existing equipment has the following shortcomings: First, the mandrel support stability is poor. For long mandrels, relying solely on the three-jaw chucks at both ends and the machine tool tip for support easily leads to sagging and wobbling in the middle, resulting in uneven cladding layer thickness, reduced precision, and affecting cladding quality. Second, the mandrel needs to be accurately installed between the three-jaw chuck and the machine tool tip for clamping and tightening. Using various lifting equipment for hoisting and clamping is inefficient and easily scratches the mandrel surface, affecting subsequent cladding results. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of low efficiency, uneven cladding thickness, and low precision in the prior art, which affect the cladding quality, and to provide a mandrel laser cladding device.

[0005] This invention is achieved through the following technical solution: A laser cladding device for mandrels includes a three-axis linear motion mechanism and a mandrel support rotation mechanism for supporting the rotation of the mandrel. The end of the three-axis linear motion mechanism is equipped with a laser cladding head. The mandrel support rotation mechanism includes a fixed, immovable three-jaw chuck and a movable machine tool tip. The base of the mandrel support rotation mechanism is provided with multiple movable mandrel support rotation frames. The mandrel support rotating frame includes a slide plate, on which two upright plates are fixedly mounted. A linear guide rail 2 is installed on one side of the upright plates, and a linear guide rail 3 is installed on the other side of the upright plates. A liftable mandrel support rotating part is installed on the linear guide rail 2, and a liftable mandrel moving part is installed on the linear guide rail 3. The mandrel support rotating part includes a lifting block, and an opening and closing cylinder is installed inside the lifting block. Two opening and closing roller frames are hinged to the piston rod of the opening and closing cylinder. Support rollers are installed inside the opening and closing roller frames. The mandrel moving part includes a lifting plate, and a roller frame is installed on the lifting plate. Two inclined moving rollers are installed on the roller frame. A motor is also installed on the roller frame. The motor drives one of the moving rollers to rotate.

[0006] Based on the length and diameter of the mandrel to be processed, adjust the position of the machine tool center so that the distance between the three-jaw chuck and the machine tool center is approximately adapted to the length of the mandrel. Based on the diameter of the mandrel, adjust the distance between the two support rollers using the opening and closing cylinder. Then, adjust the height of the mandrel moving part on the mandrel support rotating frame, placing the mandrel onto the moving roller. The motor drives the moving roller to rotate, moving the mandrel. After it moves into position, adjust the height of the mandrel moving part again to clamp the mandrel between the three-jaw chuck and the machine tool center. Then, the mandrel moving part lowers. The mandrel support rotating part rises, ensuring a tight fit between the support rollers and the mandrel surface. After adjustment, the three-jaw chuck is activated, rotating the mandrel. The external laser generator and three-axis linear motion mechanism are then activated, and the laser cladding head emits a laser beam to clad the mandrel surface. After cladding, the laser generator and three-axis linear motion mechanism are shut off, and the opening / closing cylinder is activated, causing the support rollers to release the mandrel and the three-jaw chuck, retracting the mandrel to the machine tool center. Simultaneously, the mandrel moving part rises, supporting the mandrel and pulling it out of the mandrel support rotating mechanism. By setting multiple movable mandrel support rotating frames, the middle part of the mandrel is supported at multiple points, preventing sagging and swaying due to excessive length. The opening / closing roller frame and support rollers of the mandrel support rotating part enable flexible clamping and follow-up rotation of the mandrel, reducing friction and scratches on the mandrel surface and ensuring the uniformity and precision of the cladding layer. This method provides good mandrel support stability, high cladding accuracy, smooth feeding and discharging, high efficiency, and is less prone to jamming.

[0007] Further preferred, it also includes a mandrel placement frame, which includes a frame body, on which multiple L-shaped angle steels are installed, and on the L-shaped angle steels are feeding drums. The feeding drums are in an inclined state, and all the feeding drums are connected by a feeding conveyor belt. Feeding motors are installed on the L-shaped angle steels at both ends, and the feeding motors drive the feeding drums to rotate.

[0008] Further optimization involves a tilting frame fixedly mounted on the main body of the placement rack. An end-limiting angle steel is provided at the end of the tilting frame, and an upper limit plate is fixed above the end-limiting angle steel. The mandrels to be clad are stored on the tilting frame, and each mandrel slides down from the tilting frame onto the feeding conveyor belt. The feeding motor drives the feeding drum and the feeding conveyor belt to rotate, causing the mandrels to enter the mandrel support rotation mechanism one by one. This ensures good continuity and helps improve efficiency.

[0009] Further optimization involves installing a limiting rotating cylinder I on the L-shaped angle steel, and a support rod between the two ends of the placement frame body. Multiple limiting rotating cylinder mounting plates are installed on the support rods, and limiting rotating cylinder II is installed on the limiting rotating cylinder mounting plates. When the mandrel is on the feeding conveyor belt, limiting rotating cylinder I and limiting rotating cylinder II are located on both sides of the feeding conveyor belt, playing a limiting role, and can rotate, ensuring smooth feeding and discharging of the mandrel.

[0010] Further optimization involves installing multiple pusher mounting frames at the lowest point of the inclined frame. Each pusher mounting frame is equipped with a pusher cylinder, and a pusher plate is mounted on the piston rod of each cylinder. The mandrels to be clad are stored on the inclined frame. The pusher mounting frames prevent the mandrels from slipping, and the pusher cylinders drive the pusher plates to push one mandrel at a time onto the feeding conveyor belt. This ensures that the mandrels fall accurately one by one onto the feeding conveyor belt, avoiding the possibility of multiple mandrels feeding simultaneously.

[0011] Further optimization involves a base equipped with two linear guide rails and a motor. The mandrel support rotating frame and the machine tool tip are slidably mounted on the two linear guide rails. The motor drives the machine tool tip to move via a lead screw.

[0012] Further preferably, at least one of the mandrel support rotating frames is located at the outer end of the machine tool tip. This mandrel support rotating frame is closely fitted with the mandrel placement frame, facilitating the smooth entry of mandrels from the mandrel placement frame into the mandrel support rotating mechanism one by one.

[0013] Further optimization involves installing a slider at the bottom of the slide plate, with a set screw installed inside the side of the slider. By rotating the set screw, the linear guide rail is tightened, thereby locking the position of the mandrel support rotating frame.

[0014] Further optimization involves raising the top of the upper limit plate upwards.

[0015] Further optimization involves the detachable installation of multiple rubber strips on the inclined frame. The mandrels are placed one by one on these rubber strips, which provide excellent cushioning and can be replaced if damaged.

[0016] Compared with the prior art, the beneficial effects of this invention are: Based on the length and diameter of the mandrel to be processed, adjust the position of the machine tool center so that the distance between the three-jaw chuck and the machine tool center is approximately adapted to the length of the mandrel. Based on the diameter of the mandrel, adjust the distance between the two support rollers using the opening and closing cylinder. Then, adjust the height of the mandrel moving part on the mandrel support rotating frame, placing the mandrel onto the moving roller. The motor drives the moving roller to rotate, moving the mandrel. After it moves into position, adjust the height of the mandrel moving part again to clamp the mandrel between the three-jaw chuck and the machine tool center. Then, the mandrel moving part lowers. The mandrel support rotating part rises, ensuring a tight fit between the support rollers and the mandrel surface. After adjustment, the three-jaw chuck is activated, rotating the mandrel. The external laser generator and three-axis linear motion mechanism are then activated, and the laser cladding head emits a laser beam to clad the mandrel surface. After cladding, the laser generator and three-axis linear motion mechanism are shut off, and the opening / closing cylinder is activated, causing the support rollers to release the mandrel and the three-jaw chuck, retracting the mandrel to the machine tool center. Simultaneously, the mandrel moving part rises, supporting the mandrel and pulling it out of the mandrel support rotating mechanism. By setting multiple movable mandrel support rotating frames, the middle part of the mandrel is supported at multiple points, preventing sagging and swaying due to excessive length. The opening / closing roller frame and support rollers of the mandrel support rotating part enable flexible clamping and follow-up rotation of the mandrel, reducing friction and scratches on the mandrel surface and ensuring the uniformity and precision of the cladding layer. This method provides good mandrel support stability, high cladding accuracy, smooth feeding and discharging, high efficiency, and is less prone to jamming. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 12The illustrated mandrel laser cladding equipment includes a three-axis linear motion mechanism 1 and a mandrel support rotation mechanism 3 for supporting the rotation of the mandrel. The three-axis linear motion mechanism 1 adopts an existing mature XYZ three-axis module, which can realize linear movement along the X, Y, and Z directions. A laser cladding head 2 is fixedly installed at its end by bolts. The laser cladding head 2 is connected to an external laser generator to emit a laser beam, which melts the cladding material, such as alloy powder, and deposits it on the surface of the mandrel to complete the cladding operation. The mandrel support rotation mechanism 3 includes a fixed, immovable three-jaw chuck 11 and a movable machine tool center 10. The base 5 of the mandrel support rotation mechanism 3 is provided with multiple movable mandrel support rotation frames 8. The mandrel support rotating frame 8 includes a slide plate 27. A slider is installed at the bottom of the slide plate 27, and a set screw is installed inside the side of the slider. By rotating the set screw, the linear guide rail 6 is tightened, thereby locking the position of the mandrel support rotating frame 8. Two upright plates 30 are fixedly installed on the slide plate 27. A linear guide rail 31 is installed on one side of the upright plate 30, and a linear guide rail 32 is installed on the other side of the upright plate 30. A liftable mandrel support rotating part 28 is installed on the linear guide rail 31. The mandrel support rotating part 28 is driven to lift by a motor 34. A liftable mandrel moving part 29 is installed on the linear guide rail 32. The mandrel moving part 29 is driven to lift by a motor 40. The mandrel support rotating part 28 includes a lifting block 33, an opening and closing cylinder 35 is installed inside the lifting block 33, two opening and closing roller frames 36 are hinged to the piston rod of the opening and closing cylinder 35, a support roller 38 is installed inside the opening and closing roller frame 36, and the support roller 38 is installed inside the top of the lifting block 33 by a pin 37. The mandrel moving part 29 includes a lifting plate 39, a roller frame 41 is installed on the lifting plate 39, two inclined moving rollers 43 are installed on the roller frame 41, and a motor 42 is also installed on the roller frame 41. The motor 42 drives one of the moving rollers 43 to rotate.

[0033] Based on the length and diameter of the mandrel to be processed, adjust the position of the machine tool center 10 so that the distance between the three-jaw chuck 11 and the machine tool center 10 is approximately adapted to the length of the mandrel. Based on the diameter of the mandrel, adjust the distance between the two support rollers 38 using the opening and closing cylinder 35. Then, adjust the height of the mandrel moving part 29 on the mandrel support rotating frame 8, place the mandrel on the moving roller 43, and drive the moving roller 43 to rotate, thereby moving the mandrel. After moving into position, adjust the height of the mandrel moving part 29 again to clamp the mandrel between the three-jaw chuck 11 and the machine tool center 10. Then, the mandrel moving part... The mandrel support rotating part 28 rises as the mandrel support roller 38 rises, ensuring a tight fit between the mandrel and the mandrel surface. After adjustment, the three-jaw chuck 11 is activated, rotating the mandrel. The external laser generator and three-axis linear motion mechanism 1 are activated, and the laser cladding head 2 emits a laser beam to perform cladding on the mandrel surface. After cladding, the laser generator and three-axis linear motion mechanism 1 are turned off, and the opening / closing cylinder 35 is activated, causing the support roller 38 to release the mandrel and the three-jaw chuck 11, retracting to the machine tool center 10. Simultaneously, the mandrel moving part 29 rises, supporting the mandrel and pulling it out of the mandrel support rotating mechanism 3. By setting multiple movable mandrel support rotating frames 8, the middle part of the mandrel is supported at multiple points, preventing the mandrel from sagging or swaying due to excessive length. At the same time, the opening / closing roller frame 36 and the support roller 38 of the mandrel support rotating part 28 can achieve flexible clamping and follow-up rotation of the mandrel, reducing friction and scratches on the mandrel surface and ensuring the uniformity and precision of the cladding layer. It provides good support stability for the mandrel, high cladding precision, smooth feeding and discharging, high efficiency, and is not prone to jamming.

[0034] The system also includes a mandrel placement frame 4, which includes a frame body 12. Multiple L-shaped angle steels 19 are installed on the frame body 12. Feeding drums 17 are installed on the L-shaped angle steels 19. The feeding drums 17 are inclined. All the feeding drums 17 are connected by a feeding conveyor belt 18. Feeding motors 21 are installed on the L-shaped angle steels 19 at both ends. The feeding motors 21 drive the feeding drums 17 to rotate.

[0035] At least one of the mandrel support rotating frames 8 is located at the outer end of the machine tool tip 10. The mandrel support rotating frame 8 is adjacent to the mandrel placement frame 4, which facilitates the smooth entry of the mandrels on the mandrel placement frame 4 into the mandrel support rotating mechanism 3 one by one.

[0036] An inclined frame 13 is fixedly mounted on the main body 12 of the placement rack. An end limiting angle steel 15 is provided at the end of the inclined frame 13, and an upper limit plate 16 is fixed above the end limiting angle steel 15. The top of the upper limit plate 16 is tilted upward, and the distance between the end limiting angle steel 15 and the upper limit plate 16 is sufficient for the mandrel to pass through. The mandrels to be clad are stored on the inclined frame 13. The mandrels slide one by one from the inclined frame 13 onto the feeding conveyor belt 18. The feeding motor 21 drives the feeding drum 17 and the feeding conveyor belt 18 to rotate, driving the mandrels one by one into the mandrel support rotation mechanism 3. The continuity is good, which helps to improve efficiency.

[0037] A limiting rotating drum 20 is installed on the L-shaped angle steel 19. A support rod 14 is installed between the two ends of the placement frame body 12. Multiple limiting rotating drum mounting plates 22 are installed on the support rod 14, and a second limiting rotating drum 23 is installed on the limiting rotating drum mounting plate 22. When the mandrel is on the feeding conveyor belt 18, the first limiting rotating drum 20 and the second limiting rotating drum 23 are located on both sides of the feeding conveyor belt 18, which play a limiting role and can rotate, so that the mandrel can be fed and discharged smoothly.

[0038] Multiple pusher mounting frames 24 are installed at the lowest end of the inclined frame 13. Each pusher mounting frame 24 is equipped with a pusher cylinder 25, and a pusher plate 26 is mounted on the piston rod of the pusher cylinder 25. The mandrels to be clad are stored on the inclined frame 13. The pusher mounting frames 24 prevent the mandrels from slipping. The pusher cylinder 25 drives the pusher plate 26 to push one mandrel at a time onto the feeding conveyor belt 18. This ensures that the mandrels fall accurately one by one onto the feeding conveyor belt 18, avoiding the possibility of multiple mandrels being fed simultaneously.

[0039] The base 5 is equipped with two linear guide rails 6 and a motor 7. The mandrel support rotating frame 8 and the machine tool center 10 are slidably mounted on the two linear guide rails 6. The motor 7 drives the machine tool center 10 to move through the lead screw 9.

[0040] Multiple rubber strips can be detachably installed on the inclined frame 13. The mandrels are placed on the rubber strips of the inclined frame 13, which provide good cushioning and can be replaced if damaged.

[0041] Working principle: Based on the length and diameter of the mandrel to be processed, adjust the position of the machine tool tip 10 so that the distance between the three-jaw chuck 11 and the machine tool tip 10 is approximately matched to the length of the mandrel. Based on the diameter of the mandrel, adjust the distance between the two support rollers 38 by opening and closing cylinder 35. Then, adjust the height of the mandrel moving part 29 on the mandrel support rotating frame 8. After the adjustment is completed, lock the position of the mandrel support rotating frame 8 by set screw, and the mandrel support rotating part 28 rises, so that the support rollers 38 are in close contact with the surface of the mandrel. After the adjustment is completed, start the three-jaw chuck 11 to drive the mandrel to rotate, start the external laser generator and the three-axis linear movement mechanism 1, and the laser cladding head 2 emits a laser beam to perform cladding operation on the surface of the mandrel, so that the cladding layer evenly covers the surface of the mandrel.

[0042] After the cladding is completed, the laser generator and the three-axis linear movement mechanism 1 are turned off, the three-jaw chuck 11 is released, and the machine tool center 10 is retracted. At the same time, the mandrel moving part 29 rises, supports the mandrel, and drives the mandrel to exit the mandrel support rotation mechanism 3 and enter the feeding conveyor belt 18. It then exits from the other end of the mandrel placement frame 4, completing one processing cycle.
