Description

Technical Field

[0001] This utility model relates to the field of laser cladding processing center technology, and in particular to a multi-axis linkage laser cladding processing center for oil drilling tools. Background Technology

[0002] Oil drill bits are an important component of oil drilling tools. When oil drill bits are used for a long time, they will wear out. Therefore, laser cladding is needed to process and repair worn oil drill bits.

[0003] Existing laser cladding machining centers use clamping devices to fix oil drill bits. However, the fixed position of the clamped oil drill bits makes it inconvenient to adjust their position and perform laser cladding on oil drill bits in different locations. Furthermore, when the laser cladding machining center is placed on uneven ground, it will wobble and become unstable, affecting the accuracy of subsequent laser cladding on the workpiece. To solve the above problems, this application proposes a multi-axis linkage laser cladding machining center for oil drilling tools. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-axis linkage laser cladding processing center for oil drilling tools. The X-axis and Y-axis motors can be used to adjust the position of the oil drill bit and perform laser cladding processing on different positions. The hollow legs can be rotated to move the center up and down, ensuring stable installation and precise subsequent processing.

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

A pair of first guide rails 2 are fixedly connected to the top of the base 1. Each first guide rail 2 has a first slider 3 slidably connected to its outer wall. The two first sliders 3 are fixedly connected to a moving plate 4. An X-axis adjustment structure 5 is installed between the base 1 and the moving plate 4. The X-axis adjustment structure 5 includes an X-axis motor, a first threaded rod, a first fixed block, and a first connecting block. The X-axis motor is located on the top of the base 1 and fixedly connected to it. The output end of the X-axis motor is fixedly connected to the first threaded rod. The first fixed block is located on the top of the base 1 and fixedly connected to it. The first threaded rod is rotatably connected to the side wall of the first fixed block. The bottom of the moving plate 4 is fixedly connected to the first connecting block. The first threaded rod passes through the first fixed block and is threadedly connected to it. When the X-axis motor is started, it drives the first threaded rod to rotate, which can move the workpiece in the X-axis direction.

[0026] A pair of second guide rails 6 are fixedly connected to the top of the movable plate 4. Each second guide rail 6 has a second slider 7 slidably connected to its outer wall. The two second sliders 7 are fixedly connected to the worktable 8. A Y-axis adjustment structure 9 is installed between the movable plate 4 and the worktable 8. The Y-axis adjustment structure 9 includes a Y-axis motor, a second threaded rod, a second fixed block, and a second connecting block. The Y-axis motor is located on the top of the movable plate 4 and is fixedly connected to it. The output end of the Y-axis motor is fixedly connected to the second threaded rod. The second fixed block is located on the top of the movable plate 4 and is fixedly connected to it. The second threaded rod is rotatably connected to the side wall of the second fixed block. The bottom of the worktable 8 is fixedly connected to the second connecting block. The second threaded rod passes through the second fixed block and is threadedly connected to it. When the Y-axis motor is started, it drives the second threaded rod to rotate, which can move the workpiece in the Y-axis direction.

[0027] A limiting mechanism 10 is fixedly connected to the top of the workbench 8. The limiting mechanism 10 includes a frame 10-1, a bidirectional lead screw 10-2, two sliding rods 10-3, two clamping plates 10-4, and two arc-shaped plates 10-5. The frame 10-1 is located on the top of the workbench 8 and is fixedly connected to it. The bidirectional lead screw 10-2 passes through the frame 10-1 and is rotatably connected to it. A handle is fixedly connected to one end of the bidirectional lead screw 10-2. Both sliding rods 10-3 are located on the frame 10-1 and are fixedly connected to it. The bidirectional lead screw 10-2 passes through the two clamping plates 10-4 and is threadedly connected to them. The bidirectional lead screw 10-2 has two external threads with opposite directions. Two clamping plates 10-4 are respectively set on the outer walls of the two external threads with opposite directions, which can make the two clamping plates 10-4 move relative to each other or away from each other. Two sliding rods 10-3 pass through the two clamping plates 10-4 and are slidably connected to them. Two arc-shaped plates 10-5 are respectively set at the opposite ends of the two clamping plates 10-4 and are fixedly connected to them. The two arc-shaped plates 10-5 can clamp and fix one end of the oil drill bit, thus completing the installation and fixation of the oil drill bit and ensuring the stability of the workpiece during subsequent laser cladding processing.

[0028] A U-shaped plate 11 is fixedly connected to the outer wall of the base 1. A multi-section hydraulic rod 12 is fixedly connected to the U-shaped plate 11. A laser cladding machine 13 is fixedly connected to the bottom of the multi-section hydraulic rod 12. The operator adds cladding material to the surface of the oil drill bit in advance. The laser head of the laser cladding machine 13 irradiates the surface of the oil drill bit, causing the oil drill bit and the cladding material to melt and solidify rapidly, forming a metallurgically bonded coating, thus completing the laser cladding process.

[0029] The base 1 has four adjustable legs 14 at its bottom. Each adjustable leg 14 includes a fixing screw and a hollow leg. The fixing screw is located at the bottom of the base 1 and is fixedly connected to it. The fixing screw is threadedly connected to the hollow leg. By rotating the hollow leg, it can be raised and lowered to keep the device horizontal and improve the processing accuracy. The inner wall of the U-shaped plate 11 is equipped with two symmetrically arranged fans 15. The fans 15 are square industrial exhaust fans. The fan 15 on the right is a cooling fan, and the fan 15 on the left is a suction fan. They blow air onto the processed workpiece to dissipate heat from the workpiece.

[0030] In this invention, the operator places the oil drill bit between two arc-shaped plates 10-5. The operator grips the double-ended lead screw 10-2 and rotates it, causing the clamping plates 10-4 and arc-shaped plates 10-5 on both sides to move relative to each other. The arc-shaped plates 10-5 clamp and fix the oil drill bit, ensuring the stability of the workpiece during subsequent laser cladding processing. The multi-section hydraulic rod 12 is then activated, causing the laser cladding machine 13 to move downwards. The laser cladding machine 13 can then perform laser cladding processing on the clamped oil drill bit (cladding material is pre-added to the surface of the oil drill bit; the laser head of the laser cladding machine 13 irradiates the surface of the oil drill bit, causing the oil drill bit and cladding material to melt rapidly). (The process involves solidification to form a metallurgically bonded coating). The X-axis motor is activated to rotate the first threaded rod, causing the first connecting block, moving plate 4, worktable 8, and clamped oil drill bit to move along the X-axis. The Y-axis motor is then activated to rotate the second threaded rod, causing the second connecting block, worktable 8, and clamped oil drill bit to move along the Y-axis. This movement of the clamped oil drill bit along both the X and Y axes adjusts its position, allowing for laser cladding processing at different locations on the oil drill bit. After laser cladding, two fans 15 are activated for ventilation, cooling the laser-clad areas and achieving heat dissipation and temperature reduction of the workpiece.

[0031] This invention solves the problems of existing laser cladding processing centers, which use clamping devices to fix oil drill bits. These clamping devices fix the drill bits in a fixed position, making it difficult to adjust their position and perform laser cladding on drill bits in different locations. Furthermore, when the laser cladding processing center is placed on uneven ground, it becomes unstable, affecting the accuracy of subsequent laser cladding processing on the workpiece.
