Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding, in particular to a rotating mechanism of a laser cladding device. Background Technique

[0002] Laser cladding is a technology that uses high-power lasers to melt self-fluxing metal powders for surface strengthening or rapid repair of parts. Laser cladding technology is also often used to perform cladding processing on the surface of blades during the processing of metal blades; when some laser cladding devices process blades, the blades are placed on the workbench, and the laser head performs cladding processing on the designated parts of the blades. When both sides of the blade need to be processed, the blade also needs to be flipped 180 degrees to make the unprocessed side face up. After the blade is processed by laser cladding, the surface temperature will increase. However, some existing laser cladding devices cannot automatically flip the blade, and it is easy for workers to get burned when flipping the blade, resulting in poor safety. In addition, there is no function to fix blades of different specifications and sizes, resulting in unstable blade processing and easy position deviation. Content of the Utility Model

[0003] In view of this, the utility model provides a rotating mechanism of a laser cladding device, which can automatically flip the blade, prevent the blade from burning the human hand, improve safety, and can fix blades of different specifications and sizes, improving the stability of the blade processing process.

[0004] To solve the above technical problems, the present utility model provides a rotating mechanism for a laser cladding device, including a workbench. On one side of the upper surface of the workbench, there is a fixed column, and on the other side of the upper surface of the workbench, there is a support column. At the center of one side of the fixed column, there is a first connecting rod, and at the center of one side of the support plate, there is a second connecting rod installed. Inside the fixed column, there is a driving cavity. Above the driving cavity, there is a driven gear installed, and below the driving cavity, there is a driving gear. The driving gear and the driven gear are meshed. On the outer wall of the fixed column and corresponding to the position of the driving gear, there is a motor. The output end of the motor penetrates the outer wall of the fixed column and is connected to the center of the end of the driving gear. One end of the first connecting rod penetrates the outer wall of the fixed column and is connected to the center of the end of the driven gear. At the ends of both the first connecting rod and the second connecting rod, there are connecting pipes. On both sides inside the connecting pipes, there are telescopic push rods. The output end of the telescopic push rod is provided with a fixed block. On one side of the fixed block, there is a clamping frame. Inside the clamping frame, there is a clamping mechanism for fixing blades of different thicknesses. The staff places the workbench under the laser head, then places the blade to be processed between the two clamping frames, and then starts the telescopic push rod to retract the output end of the telescopic push rod, so that the fixed block drives the two clamping frames to approach each other, making both sides of the blade clamped inside the clamping frames. Then, the blade is fixed by the clamping mechanism, and then the upper surface of the blade can be subjected to cladding processing. When it is necessary to process the lower surface of the blade, start the motor. The output end of the motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate. The driven gear drives the connecting rod to rotate. The connecting rod drives the connecting pipe to rotate synchronously. The connecting pipe drives the clamping frame to rotate synchronously, so that the clamping frame drives the blade to flip its position, which can automatically flip the blade, prevent the blade from scalding the human hand, improve safety, and can fix blades of different specifications and sizes through the clamping mechanism, improving the stability of the blade processing process.

[0005] Inside the support column and corresponding to the position of the second connecting rod, there is a first bearing. The outer ring of the first bearing is fixed to the inner wall of the support column, and the surface of the second connecting rod is fixed to the inner ring of the first bearing. When the second connecting rod rotates following the first connecting rod, the first bearing supports the second connecting rod, making the blade flipping process more stable.

[0006] The clamping mechanism includes a screw rod threadedly connected to the center of the upper surface of the clamping frame. There is a threaded hole at the center of the upper surface of the clamping frame, and the screw rod is threadedly connected to the threaded hole of the clamping frame. At the upper end of the screw rod, there is a handle. At the lower end of the screw rod, there is a second bearing. The lower end of the screw rod is fixed to the inner ring of the second bearing, and the outer ring of the second bearing is fixed with a pressing plate. After the staff clamps both sides of the blade into the inside of the clamping frame, turn the handle. The handle drives the screw rod to rotate. Since the screw rod is threadedly connected to the threaded hole of the clamping frame, when the screw rod rotates, it drives the pressing plate to press down through the second bearing, making the pressing plate press the blade tightly, and thus can clamp and fix blades of different thicknesses, improving the stability of the blade clamping process and the applicability of the device.

[0007] The two inner side walls of the clamping frame are provided with sliding grooves, and both ends of the pressing plate are provided with sliding blocks. The sliding blocks are slidably arranged in the sliding grooves. The sliding blocks move downward following the pressing plate, and the sliding blocks slide in the sliding grooves to prevent the pressing block from tilting.

[0008] The lower surface of the pressing plate is provided with a serrated mechanism to increase the friction force on the blade, thereby improving the fixing effect.

[0009] The handle is made of wood, and the surface of the handle is provided with anti-slip threads to prevent the hand from slipping.

[0010] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0011] 1. When the present utility model is in use, the staff places the workbench under the laser head, then places the blade to be processed between the two clamping frames, and then starts the telescopic push rod to retract the output end of the telescopic push rod, so that the fixed block drives the two clamping frames to approach each other, and both sides of the blade are clamped in the clamping frames. Then, the blade is fixed by the clamping mechanism, and then the upper surface of the blade can be subjected to cladding processing. When it is necessary to process the lower surface of the blade, start the motor. The output end of the motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the connecting rod to rotate, the connecting rod drives the connecting pipe to rotate synchronously, and the connecting pipe drives the clamping frame to rotate synchronously, so that the clamping frame drives the blade to flip its position, thereby automatically flipping the blade, preventing the blade from scalding the hand, improving safety, and being able to fix blades of different specifications and sizes through the clamping mechanism, improving the stability of the blade processing process.

[0012] 2. When the present utility model is in use, a first bearing is arranged inside the support column corresponding to the position of the second connecting rod. The outer ring of the first bearing is fixed to the inner wall of the support column, and the surface of the second connecting rod is fixed to the inner ring of the first bearing. When the second connecting rod rotates following the first connecting rod, the first bearing supports the second connecting rod, making the blade flipping process more stable.

[0013] 3. When the present utility model is in use, after the staff clamps both sides of the blade into the inside of the clamping frame, turn the handle. The handle drives the screw rod to rotate. Since the screw rod is threadedly connected to the threaded hole of the clamping frame, when the screw rod rotates, it drives the pressing plate to press down through the second bearing, so that the pressing plate presses the blade tightly, and thus can clamp and fix blades of different thicknesses, improving the stability of the blade clamping process and the applicability of the device.

[0020] According to an embodiment of the present utility model, as Figure 1 and Figure 2As shown in the figure: This embodiment provides a rotating mechanism for a laser cladding device, including a workbench 100. On one side of the upper surface of the workbench 100, a fixed column 200 is provided. On the other side of the upper surface of the workbench 100, a support column 300 is provided. At the center of one side of the fixed column 200, a first connecting rod 201 is provided. At the center of one side of the support plate, a second connecting rod 301 is installed. A driving cavity 203 is opened inside the fixed column 200. Above the driving cavity 203, a driven gear 205 is installed. Below the driving cavity 203, a driving gear 204 is installed. The driving gear 204 and the driven gear 205 are meshed. On the outer wall of the fixed column 200 and corresponding to the position of the driving gear 204, a motor 202 is provided. The output end of the motor 202 penetrates the outer wall of the fixed column 200 and is connected to the center of the end of the driving gear 204. One end of the first connecting rod 201 penetrates the outer wall of the fixed column 200 and is connected to the center of the end of the driven gear 205. Connecting pipes 400 are provided at the ends of both the first connecting rod 201 and the second connecting rod 301. Telescopic push rods 401 are provided on both sides inside the connecting pipe 400. The output end of the telescopic push rod 401 is provided with a fixed block 402. On one side of the fixed block 402, a clamping frame 500 is provided. A clamping mechanism for fixing blades of different thicknesses is provided inside the clamping frame 500. The staff places the workbench 100 under the laser head, and then places the blade to be processed between the two clamping frames 500. Then, the telescopic push rod 401 is started, and the output end of the telescopic push rod 401 is retracted, so that the fixed block 402 drives the two clamping frames 500 to approach each other, and both sides of the blade are clamped inside the clamping frame 500. Then, the blade is fixed by the clamping mechanism. Then, the upper surface of the blade can be subjected to cladding processing. When it is necessary to process the lower surface of the blade, the motor 202 is started. The output end of the motor 202 drives the driving gear 204 to rotate. The driving gear 204 drives the driven gear 205 to rotate. The driven gear 205 drives the connecting rod to rotate. The connecting rod drives the connecting pipe 400 to rotate synchronously. The connecting pipe 400 drives the clamping frame 500 to rotate synchronously. Further, the clamping frame 500 drives the blade to flip its position, so that the blade can be automatically flipped, preventing the blade from scalding the human hand and improving safety. Inside the support column 300 and corresponding to the position of the second connecting rod 301, a first bearing 302 is provided. The outer ring of the first bearing 302 is fixed to the inner wall of the support column 300. The surface of the second connecting rod 301 is fixed to the inner ring of the first bearing 302. When the second connecting rod 301 rotates following the first connecting rod 201, the first bearing 302 supports the second connecting rod 301, making the blade flipping process more stable;

[0021] According to another embodiment of the present invention, as Figure 1 and Figure 3As shown in the figure, the clamping mechanism includes a screw rod 501 threadedly connected to the center of the upper surface of the clamping frame 500. A threaded hole is provided at the center of the upper surface of the clamping frame 500, and the screw rod 501 is threadedly connected to the threaded hole of the clamping frame 500. A handle 502 is provided at the upper end of the screw rod 501, and a second bearing 503 is provided at the lower end of the screw rod 501. The lower end of the screw rod 501 is fixed to the inner ring of the second bearing 503, and a pressing plate 504 is fixed to the outer ring of the second bearing 503. After the staff clamps the two sides of the blade into the inside of the clamping frame 500, turn the handle 502. The handle 502 drives the screw rod 501 to rotate. Since the screw rod 501 is threadedly connected to the threaded hole of the clamping frame 500, when the screw rod 501 rotates, it drives the pressing plate 504 to press down through the second bearing 503, so that the pressing plate 504 presses the blade tightly, and thus the blades with different thicknesses can be clamped and fixed, improving the stability of the blade clamping process and the applicability of the device; sliding grooves 505 are provided on the two inner side walls of the clamping frame 500, and sliding blocks 506 are provided at both ends of the pressing plate 504.

[0022] Usage method of the present utility model:

[0023] The staff places the workbench 100 under the laser head, and then places the blade to be processed between the two clamping frames 500. Then, start the telescopic push rod 401 to retract the output end of the telescopic push rod 401, so that the fixed block 402 drives the two clamping frames 500 to approach each other, and the two sides of the blade are clamped in the clamping frames 500. Then, turn the handle 502. The handle 502 drives the screw rod 501 to rotate. Since the screw rod 501 is threadedly connected to the threaded hole of the clamping frame 500, when the screw rod 501 rotates, it drives the pressing plate 504 to press down through the second bearing 503, so that the pressing plate 504 presses the blade tightly to fix the blade. Then, the upper surface of the blade can be subjected to cladding processing. When it is necessary to process the lower surface of the blade, start the motor 202. The output end of the motor 202 drives the driving gear 204 to rotate. The driving gear 204 drives the driven gear 205 to rotate. The driven gear 205 drives the connecting rod to rotate. The connecting rod drives the connecting pipe 400 to rotate synchronously. The connecting pipe 400 drives the clamping frame 500 to rotate synchronously, and then the clamping frame 500 drives the blade to flip its position, thereby automatically flipping the blade, preventing the blade from scalding the human hand, improving safety, and the clamping mechanism can fix blades with different specifications and sizes, improving the stability of the blade processing process.
