Description

Technical Field

[0001] This utility model relates to the field of laser cladding device technology, and in particular to a multi-nozzle laser cladding device. Background Technology

[0002] The multi-nozzle laser cladding device is a high-energy laser processing equipment used for surface modification and repair of tubular materials. It uses a high-energy laser beam to heat powder materials to a molten state and sprays the molten powder onto the substrate surface through multiple nozzles. After cooling, it forms a multi-layer cladding layer with specific properties.

[0003] However, most of the existing multi-nozzle laser cladding devices on the market are not convenient for workers to fix workpieces of different lengths, making operation difficult. In addition, most of the existing multi-nozzle laser cladding devices on the market are not convenient to collect the excess powder sprayed from the nozzles, causing the sputtered powder to float in the workshop and reduce the quality of the working environment.

[0004] Therefore, those skilled in the art have provided a multi-nozzle laser cladding device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-nozzle laser cladding device. The device uses a turntable in the limiting mechanism to drive a bidirectional threaded rod to clamp the workpiece with a clamping block. A first servo motor drives the first threaded rod to move a stop block to hold the workpiece in place, facilitating workpiece fixation. A fan in the collection mechanism connects to a collection box via a filter pipe, creating a negative pressure inside the collection box. A suction pipe and connecting pipe are used to draw floating powder into the collection box.

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

[0007] A multi-nozzle laser cladding device includes a worktable, a limiting mechanism, and a collecting mechanism. A fixing block is fixedly connected to the middle of the other side of the upper end of the worktable. The limiting mechanism is provided at the upper end of the worktable. The limiting mechanism includes a rotating seat, a bidirectional threaded rod, and a stop block. A groove is formed on the outer wall of one side of the rotating seat. The bottom surface inside the groove is rotatably connected to the bidirectional threaded rod. The upper end of the bidirectional threaded rod passes through the rotating seat and is fixedly connected to a turntable. The upper and lower ends of the outer wall of the bidirectional threaded rod are threadedly connected to clamping blocks. The clamping blocks are slidably connected to the groove. A moving groove is formed in the middle of the upper end of the worktable.

[0008] A first servo motor is provided at the front end of the inner wall on the other side of the moving groove. The output shaft of the first servo motor is fixedly connected to a first threaded rod. A moving block is threadedly connected to the outer wall of the first threaded rod. A third servo motor is provided at the rear end of the inner wall on the other side of the moving groove. A second threaded rod is fixedly connected to the output shaft of the third servo motor. One side of the second threaded rod is rotatably connected to the moving groove. A collection mechanism is provided at the rear end of the worktable. The collection mechanism includes a support block and a filter tube. Multiple laser nozzles are fixedly connected to the upper end of the outer wall at the front end of the support block.

[0009] The above technical solution involves a turntable driving a bidirectional threaded rod to rotate within a rotating seat. A clamping block is threadedly connected to the bidirectional threaded rod, allowing the clamping block to move along a slide groove to clamp one end of the workpiece. In conjunction with a first servo motor driving the first threaded rod to rotate within a moving groove, a moving block is threadedly connected to the first threaded rod, causing the moving block to drive a stop block to move along the moving groove, thus stopping the other end of the workpiece and fixing it in place.

[0010] Furthermore, a dust collection hood is fixedly connected to the upper end of the outer walls on both sides of the support block, and a dust collection pipe is connected through the side of the dust collection hood away from the center of the support block.

A fan is provided on the other side of the rear end of the lower end of the workbench, and one side of the filter pipe is fixedly connected to the collection box by multiple bolts.

[0011] The above technical solution connects the collection box and the suction pipe through a connecting pipe, and the suction pipe is connected to the suction hood fixedly connected to the support block. With the help of the fan, the filter pipe is connected to the collection box, so that a negative pressure is formed inside the collection box. Excess powder sprayed from the nozzle is sucked into the collection box through the suction pipe and the connecting pipe, reducing the floating powder.

[0012] Furthermore, support legs are fixedly connected to the four corners of the lower end of the workbench, and a PLC control panel is fixedly connected to one side of the outer wall of the front end of the workbench.

[0013] By using the above technical solution, four support legs are fixedly connected to the lower end of the workbench, which makes the device more stable during operation and keeps the device at a certain height from the ground, making it easier for operators to operate. The PLC control panel fixedly connected to the workbench allows operators to control the operating status of the device.

[0014] Furthermore, a second servo motor is provided in the cavity inside the fixed block. The output shaft of the second servo motor passes through the fixed block and is fixedly connected to the rotating seat. The upper end of the outer wall on the other side of the moving block is rotatably connected to the abutment block.

[0015] Through the above technical solution, by fixing the output shaft of the second servo motor inside the fixed block to the rotating seat, when the workpiece is clamped by the clamping block and pressed against the abutment connected to the moving block, the second servo motor can drive the workpiece to rotate slowly. The powder feeding pipes on multiple laser nozzles are connected to the powder feeder to spray out powder, which is melted by the laser nozzle and combined with the melted surface of the workpiece to perform a cladding operation.

[0016] Furthermore, one side of the first threaded rod is rotatably connected to the movable groove, and the movable block is slidably connected to the movable groove;

[0017] The above technical solution involves driving the first threaded rod to rotate via a first servo motor, and connecting the moving block to the first threaded rod via a threaded connection, so that the rotating first threaded rod drives the moving block to move along the moving groove on the worktable.

[0018] Furthermore, guide rods are fixedly connected to the middle of the inner walls on both sides of the movable groove, and the outer wall of the guide rod body is slidably connected to the movable block;

[0019] By using the above technical solution, the guide rod, which is fixedly connected inside the moving groove, is slidably connected to the moving block, making the moving block move more stably along the moving groove.

[0020] Furthermore, the outer wall of the second threaded rod body is threadedly connected to the support block, and the support block is slidably connected to the moving groove;

[0021] The above technical solution involves using a third servo motor to drive the second threaded rod to rotate within the moving groove. The support block is threadedly connected to the second threaded rod, allowing the rotating second threaded rod to move the support block along the moving groove on the worktable, thereby changing the position of the laser nozzle fixedly connected to the support block.

[0022] Furthermore, the air inlet of the fan is fixedly connected to the filter pipe by multiple bolts, and the air outlet of the fan is fixedly connected to the exhaust pipe by multiple bolts.

[0023] The above technical solution allows the filter tube to be fixedly connected to the air inlet of the fan and the collection box by multiple bolts. This allows the staff to remove the filter tube for cleaning or replacement after unscrewing the bolts. The fan creates negative pressure inside the collection box, and the floating dust is sucked into the collection box by the connecting pipe and the dust suction pipe. The dust is separated from the air by the filter tube and then discharged through the exhaust pipe fixedly connected to the air outlet of the fan.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a multi-nozzle laser cladding device, which drives a bidirectional threaded rod to rotate in a rotating seat by a turntable in a limiting mechanism.

[0040] Working Principle: When using this multi-nozzle laser cladding device, the operator first powers the device with an external power supply. Then, the operator rotates the turntable 504, causing the bidirectional threaded rod 503 to move along the slide groove 502 using the clamping block 505, clamping one end of the workpiece. Simultaneously, the PLC control panel 3 activates the first servo motor 507, driving the first threaded rod 508, which in turn moves the abutment block 510 along the moving groove 506 using the moving block 509, thus abutting the other end of the workpiece and fixing its position. Next, the operator uses the PLC control panel 3 to activate the second servo motor 6, driving the rotating seat 501 to rotate. With the abutment block 510 and the moving block 509 rotatably connected, the workpiece begins to rotate. Simultaneously, the third servo motor 7 is activated via the PLC control panel 3 to drive the second threaded rod 8, which in turn moves the support block 901 along the moving groove 506. The powder is then sprayed from the powder feeding pipes on both sides of the laser nozzle 10 by the powder feeder. The powder is melted by the laser nozzle 10 and combines with the surface of the workpiece that has been melted by the laser irradiation to perform a cladding operation. Finally, during the cladding operation, the operator activates the fan 906 via the PLC control panel 3. The filter pipe 908 is connected to the collection box 905, creating a negative pressure inside the collection box 905. This draws the excess powder sprayed from the nozzle into the collection box 905 through the suction pipe 903 and the connecting pipe 904, reducing the amount of excess powder that is splashed out and floating in the workshop.
