Description

Technical Field

[0001] This utility model relates to the field of oil drilling bit manufacturing technology, and in particular to a device for remanufacturing oil drilling bits based on laser cladding. Background Technology

[0002] When drilling for oil, oil is typically done using an oil drilling bit. Over time, the surface of the oil drilling bit will wear down, so it is necessary to remanufacture and repair the surface of the oil drilling bit.

[0003] When repairing oil drilling bits, workers typically hold the drill bit in one hand and a laser cladding gun in the other. However, this process is prone to injury, and holding the drill bit in one hand can cause it to shake during laser cladding, leading to instability and affecting the processing results. To address these issues, this application proposes a remanufacturing device for oil drilling bits based on laser cladding. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a remanufacturing device for oil drilling bits based on laser cladding. By setting a clamping mechanism, the oil drilling bit can be clamped and fixed to ensure the stability of the workpiece during subsequent laser cladding processing. By adjusting the mechanism and driving the rotation of the drill bit by a motor, different positions of the drill bit can be clad and repaired for remanufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for remanufacturing oil drilling bits based on laser cladding includes a worktable. A motor is fixedly connected to the bottom of the worktable. The output shaft of the motor passes through the worktable and is rotatably connected to it. A drive gear is fixedly connected to the end of the output shaft of the motor. The drive gear meshes with a driven gear. A rotating rod is fixedly connected to the driven gear on the same axis. The bottom of the rotating rod is rotatably connected to the top of the worktable. A rotating disk is fixedly connected to the top of the rotating rod. An oil drilling bit body is placed on the rotating disk. A clamping mechanism is provided on the rotating disk. A U-shaped plate is fixedly connected to the top of the worktable. A laser cladding gun head is provided on one side of the oil drilling bit body. An adjustment mechanism is provided on the laser cladding gun head.

[0007] Preferably, the clamping mechanism includes a lead screw that passes through and is rotatably connected to the rotating disk. A handle is fixedly connected to one end of the lead screw away from the rotating disk. Two L-shaped plates are threadedly connected to the outer wall of the lead screw. Both L-shaped plates are slidably connected to the rotating disk. C-shaped clamps are fixedly connected to the opposite ends of the two L-shaped plates. Both C-shaped clamps are abutted against the outer wall of the oil drilling bit body.

[0008] Preferably, the adjustment mechanism includes two L-shaped rods fixedly connected to the U-shaped plate, and the two L-shaped rods are fitted with a slider that is slidably connected to them. An X-axis hydraulic rod is fixedly connected to the side wall of the slider. The X-axis hydraulic rod is fixedly connected to the inner wall of the U-shaped plate. A Z-axis hydraulic rod is fixedly connected to the bottom of the X-axis hydraulic rod. The bottom of the Z-axis hydraulic rod is fixedly connected to the laser cladding gun head.

[0009] Preferably, the lead screw is provided with two external threads with opposite directions, and the two L-shaped plates are respectively sleeved on the outer walls of the two external threads with opposite directions.

[0010] Preferably, the top of the rotating disk has two sliding grooves, and the two L-shaped plates are respectively located in their corresponding sliding grooves and are slidably connected to the groove walls.

[0011] Preferably, each of the two C-shaped clamps has a protective layer at its opposite ends, and the protective layer is made of rubber.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The operator holds the handle and rotates it to drive the lead screw to rotate, causing the L-shaped plates and C-shaped clamps on both sides to move relative to each other until the two C-shaped clamps abut against the two ends of the oil drilling bit body, thus clamping and fixing the oil drilling bit body. This ensures the stability of the oil drilling bit body during subsequent laser cladding processing, replacing the need for hand-held bit fixing and ensuring the safety of personnel.

[0014] 2. Start the X-axis hydraulic rod to move the slider, Z-axis hydraulic rod, and laser cladding gun head in the X-axis direction. Start the Z-axis hydraulic rod to move the laser cladding gun head in the Z-axis direction. The position of the laser cladding gun head can be adjusted to perform laser cladding processing on the far right side of the oil drilling bit body.

[0015] 3. The output shaft of the motor drives the drive gear, driven gear, rotating rod, rotating disk and clamped oil drilling bit body to rotate, which can perform laser cladding processing on different surfaces of the oil drilling bit body, thus completing the full laser cladding processing of the oil drilling bit body and completing the repair and remanufacturing operation of the oil drilling bit body.

[0016] In summary, by setting up a clamping mechanism, the oil drilling bit can be clamped and fixed to ensure the stability of the workpiece during subsequent laser cladding processing. By adjusting the mechanism and driving the rotation of the drill bit by a motor, different positions of the drill bit can be clad repaired and remanufactured. Attached Figure Description

The drive gear 3 meshes with a driven gear 4. A rotating rod 5 is fixedly connected to the driven gear 4 on the same axis. The bottom of the rotating rod 5 is rotatably connected to the top of the worktable 1. A rotating disk 6 is fixedly connected to the top of the rotating rod 5. An oil drilling bit body 9 is placed on top of the rotating disk 6. The motor 2 can drive the rotating disk 6 and the oil drilling bit body 9 to rotate, and laser cladding operations can be performed on different positions of the oil drilling bit body 9.

[0023] The rotating disk 6 is equipped with a clamping mechanism, which includes a lead screw 7 that passes through and is rotatably connected to the rotating disk 6. A handle 8 is fixedly connected to the end of the lead screw 7 away from the rotating disk 6. Two L-shaped plates 10, threadedly connected to the lead screw 7, are fitted onto the outer wall of the lead screw 7. The lead screw 7 has two sections of external threads with opposite directions. The two L-shaped plates 10 are respectively fitted onto the outer walls of the two sections of opposite external threads. Rotation of the lead screw 7 allows the L-shaped plates 10 on both sides to move relative to or away from each other. Both L-shaped plates 10 are slidably connected to the rotating disk 6. Two sliding grooves are provided on the top of the rotating disk 6. Each L-shaped plate 10 is located in its corresponding sliding groove and is slidably connected to the groove wall, which can limit the movement of the L-shaped plate 10 and make it stable. C-shaped clamping plates 11 are fixedly connected to the opposite ends of the two L-shaped plates 10. The two C-shaped clamping plates 11 are abutted against the outer wall of the oil drilling bit body 9. The opposite ends of the two C-shaped clamping plates 11 are provided with a protective layer. The protective layer is made of rubber, which can clamp and fix the oil drilling bit body 9. The protective layer can protect the clamped oil drilling bit body 9 and ensure the stability of the workpiece during laser cladding operation.

[0024] A U-shaped plate 12 is fixedly connected to the top of the workbench 1. A laser cladding gun head 17 is provided on one side of the oil drilling bit body 9. The laser cladding gun head 17 can emit a laser to heat and melt the alloy powder pre-applied to the surface of the oil drilling bit body 9, thereby completing the repair and remanufacturing of the surface of the oil drilling bit body 9.

[0025] The laser cladding gun head 17 is equipped with an adjustment mechanism, which includes two L-shaped rods 13 fixedly connected to the U-shaped plate 12. The two L-shaped rods 13 are fitted with a slider 14 that is slidably connected to them. An X-axis hydraulic rod 15 is fixedly connected to the side wall of the slider 14. The X-axis hydraulic rod 15 is fixedly connected to the inner wall of the U-shaped plate 12. A Z-axis hydraulic rod 16 is fixedly connected to the bottom of the X-axis hydraulic rod 15. The bottom of the Z-axis hydraulic rod 16 is fixedly connected to the laser cladding gun head 17. By setting the X-axis hydraulic rod 15 and the Z-axis hydraulic rod 16, the position of the laser cladding gun head 17 can be adjusted. Through the rotation of the oil drilling bit body 9, repair and manufacturing operations can be performed on different positions of the oil drilling bit body 9.

[0026] In this invention, the operator places the worn oil drilling bit body 9, which needs repair, onto the rotary table 6. The operator holds the handle 8 and rotates it, causing the lead screw 7 to rotate. This moves the L-shaped plates 10 and C-shaped clamping plates 11 on both sides relative to each other until the two C-shaped clamping plates 11 abut against both ends of the oil drilling bit body 9, thus clamping and fixing the oil drilling bit body 9 and ensuring its stability during subsequent laser cladding processing. Laser cladding processing can be performed on the clamped and limited oil drilling bit body 9 using the laser cladding gun head 17. This technology is existing and will not be described in detail here. The X-axis hydraulic rod 15 is activated to drive the slider 14 and Z... The hydraulic rod 16 and the laser cladding gun 17 move in the X-axis direction. The Z-axis hydraulic rod 16 is activated to drive the laser cladding gun 17 to move in the Z-axis direction. The position of the laser cladding gun 17 can be adjusted to perform laser cladding processing on the rightmost side of the oil drilling bit body 9. The motor 2 is activated, and the output shaft of the motor 2 drives the drive gear 3, driven gear 4, rotating rod 5, rotating disk 6 and the clamped oil drilling bit body 9 to rotate. Laser cladding processing can be performed on different surfaces of the oil drilling bit body 9, thus completing the full laser cladding processing of the oil drilling bit body 9 and completing the repair and remanufacturing operation of the oil drilling bit body 9.

[0027] This invention solves the problem of existing technology where workers hold an oil drilling drill bit in one hand and a laser cladding gun in the other for repair work. This is because the drill bit is held by hand, which can easily cause injury during repair work. Furthermore, holding the drill bit by hand can cause it to shake during laser cladding, resulting in instability and affecting the processing effect.
