This device is designed based on this need and aims to achieve efficient and precise laser coating operation of drill bits.

[0003] However, existing laser coating devices for drill bit processing still have some shortcomings in practical applications: some devices are not adaptable to different specifications of drill bits and cannot meet diverse production needs; and some devices do not have sufficient positioning accuracy and stability in the laser coating process, which affects the quality and uniformity of the coating. Utility Model Content

[0004] The main objective of this invention is to provide a laser coating device for drill bit processing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A laser coating device for drill bit processing includes a base plate, with support feet fixedly connected to the four corners of the lower end of the base plate. A limit groove is formed in the middle of the upper end of the base plate. A fixing plate is fixedly connected to the upper left and upper right parts of the base plate. A clamping device is fixedly connected to the left end of the left fixing plate. An electric telescopic rod is fixedly connected to the upper front and upper rear parts of the base plate. The output ends of the two electric telescopic rods are fixedly connected to a lifting plate. A vertically through movable groove is formed in the middle of the upper end of the lifting plate. An adjustment device is fixedly connected to the upper front and right rear parts of the lifting plate.

[0007] The adjustment device includes two side plates. A second rotary motor is fixedly connected to the front end of the front side plate. A movable rod is fixedly connected to the output end of the second rotary motor through the front side plate. A connecting sleeve is fixedly connected to the middle of the outer surface of the movable rod. A flip plate is fixedly connected to the middle of the outer surface of the connecting sleeve. A coating component is fixedly connected to the right inner wall of the flip plate.

[0008] Preferably, the left ends of the two side plates are fixedly connected to the front right end and the rear right end of the lifting plate, respectively, and the two side plates are distributed in a front-to-back mirror image.

[0009] Preferably, the rear end of the movable rod is movably connected to the front end of the rear side plate via a bearing.

[0010] Preferably, the movable rod and the connecting sleeve are integrally fixedly connected.

[0011] Preferably, the coating assembly includes an arc-shaped connecting plate, the inner wall of which is fixedly connected to three second fixing posts, the ends of which are all away from the arc-shaped connecting plate are fixedly connected to a laser emitter body, a focusing lens is fixedly installed at the lower end of the laser emitter body, and the outer surface of the arc-shaped connecting plate is fixedly connected to the inner wall of the flip plate.

[0012] Preferably, the clamping device includes a first rotary motor, the output end of which is fixedly connected to a bidirectional threaded rod through the left fixed plate. Threaded loops are threadedly connected to the left and right outer surfaces of the bidirectional threaded rod. Limiting plates are fixedly connected to the lower ends of the two threaded loops, and connecting blocks are fixedly connected to the upper ends of the two threaded loops. First fixing posts are fixedly connected to the inner surfaces of the two connecting blocks, and clamping discs are fixedly connected to the inner surfaces of the two first fixing posts.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, a first rotary motor drives a bidirectional threaded rod, which in turn moves the two threaded sleeves in opposite directions, thereby achieving automatic adjustment of the clamping plate. This allows for quick adaptation to drill bits of different diameters, such as 3-20mm, without the need for frequent clamp changes, significantly improving production efficiency. Traditional devices require manual replacement of specific clamps, which is cumbersome and time-consuming.

[0017] In this invention, the second rotary motor drives the laser head assembly to achieve a wide range of rotation, enabling all-around coating of complex curved surfaces such as the drill bit's spiral grooves and cutting edges. This combination of high-precision positioning and multi-angle coating avoids uneven coating caused by positional deviations or coating dead angles, ensuring consistent coating thickness across all parts of the drill bit, improving the bonding strength between the coating and the drill bit, and significantly enhancing the overall quality of laser coating.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A laser coating device for drill bit processing includes a base plate 1. Support feet 2 are fixedly connected to the four corners of the lower end of the base plate 1. A limit groove 3 is opened in the middle of the upper end of the base plate 1. Fixing plates 4 are fixedly connected to the upper left and upper right parts of the base plate 1. A clamping device 5 is fixedly connected to the left end of the left fixing plate 4. Electric telescopic rods 6 are fixedly connected to the upper front and upper rear parts of the base plate 1. The output ends of the two electric telescopic rods 6 are fixedly connected to a lifting plate 7. A vertical through-hole movable groove 8 is opened in the middle of the upper end of the lifting plate 7. An adjustment device 9 is fixedly connected to the right front and right rear parts of the lifting plate 7.

[0029] In this embodiment, the adjusting device 9 includes two side plates 91. A second rotary motor 92 is fixedly connected to the front end of the front side plate 91. The output end of the second rotary motor 92 passes through the front side plate 91 and is fixedly connected to a movable rod 93. A connecting sleeve 94 is fixedly connected to the middle of the outer surface of the movable rod 93. A flip plate 95 is fixedly connected to the middle of the outer surface of the connecting sleeve 94. A coating assembly 96 is fixedly connected to the right inner wall of the flip plate 95. The left ends of the two side plates 91 are fixedly connected to the front right end and the rear right end of the lifting plate 7, respectively, and the two side plates 91 are in a front-to-back mirror configuration. The distribution is as follows: the rear end of the movable rod 93 is movably connected to the front end of the rear side plate 91 via a bearing; the movable rod 93 and the connecting sleeve 94 are integrally fixedly connected; the coating assembly 96 includes an arc-shaped connecting plate 961, three second fixing posts 962 are fixedly connected to the inner wall surface of the arc-shaped connecting plate 961, and the laser emitter body 963 is fixedly connected to the end of each of the three second fixing posts 962 away from the arc-shaped connecting plate 961; a focusing lens 964 is fixedly installed at the lower end of the laser emitter body 963; and the outer surface of the arc-shaped connecting plate 961 is fixedly connected to the inner wall surface of the flip plate 95.

[0030] Through the above scheme: the side plate 91 is fixedly connected to the lifting plate 7 to provide support for the entire adjustment device 9. The mirror-distributed side plates 91 ensure the stable installation of the movable rod 93. The front end of the movable rod 93 is connected to the second rotary motor 92, and the rear end is connected to the rear side plate 91 through the bearing to form a rotatable structure. The second rotary motor 92 starts → drives the movable rod 93 to rotate. The movable rod 93 drives the flip plate 95 to rotate synchronously through the integrated connecting sleeve 94. The coating component 96 on the inner wall of the flip plate 95 flips accordingly to realize the adjustment of the laser coating angle. The arc-shaped connecting plate 961 firmly supports the laser emitter body 963 through three second fixed columns 962. The laser emitter body 963 emits a laser beam, which is focused by the focusing lens 964 and acts on the surface of the drill bit. The flipping range of the flip plate 95 determines the angle area that the laser beam can cover, realizing all-round coating of complex structures such as the drill bit's spiral grooves and cutting edges. The electric telescopic rod 6 adjusts the height of the lifting plate 7 → controls the vertical position of the coating component 96, and cooperates with the clamping device 5 to make the laser beam accurately aligned with the area to be processed, ensuring the uniformity of the coating.

[0031] In this embodiment, the clamping device 5 includes a first rotary motor 51. The output end of the first rotary motor 51 is fixedly connected to a bidirectional threaded rod 52 through the left fixed plate 4. The left and right outer surfaces of the bidirectional threaded rod 52 are threaded with threaded loops 53. The lower ends of the two threaded loops 53 are fixedly connected to limit plates 54. The upper ends of the two threaded loops 53 are fixedly connected to connecting blocks 55. The inner surfaces of the two connecting blocks 55 are fixedly connected to first fixing posts 56. The inner surfaces of the two first fixing posts 56 are fixedly connected to clamping discs 57. The right end of the first rotary motor 51 is fixedly connected to the left end of the left fixed plate 4. The rear end of the bidirectional threaded rod 52 is movably connected to the front end of the rear fixed plate 4 through a bearing. The two limit plates 54 are both disposed in the limit grooves 3.

[0032] Through the above scheme: the first rotary motor 51 starts → the output shaft drives the bidirectional threaded rod 52 to rotate. The bidirectional threaded rod 52 is connected to the rear fixed plate 4 through the bearing to ensure stable rotation. The left and right threads of the bidirectional threaded rod 52 have opposite directions of rotation → driving the two threaded loops 53 to move synchronously in opposite directions. The limiting plate 54 at the lower end of the threaded loop 53 slides in the limiting groove 3 to limit its rotation and ensure linear movement. The threaded loop 53 drives the first fixed column 56 to move through the connecting block 55. The first fixed column 56 pushes the clamping plate 57 closer to the drill bit → achieving automatic centering and clamping. Reversing the first rotary motor 51 → the clamping plate 57 is released, completing the drill bit disassembly. This design achieves synchronous clamping through a single motor drive. It has a compact structure and high positioning accuracy, effectively improving the equipment's adaptability to different specifications of drill bits and clamping efficiency.

[0033] It should be noted that this utility model is a laser coating device for drill bit processing. During use, firstly, the first rotary motor 51 is started → the bidirectional threaded rod 52 drives the threaded loop 53 to move in the opposite direction, the clamping plate 57 opens → the drill bit to be processed is placed in → the motor reverses to make the clamping plate 57 clamp the drill bit, the limiting plate 54 slides within the limiting groove 3 to ensure stable clamping, the electric telescopic rod 6 rises and falls → the lifting plate 7 is adjusted to the target height, the second rotary motor 92 drives the movable rod 93 to rotate, the connecting sleeve 94 drives the flipping plate 95 to flip → the angle of the laser emitter body 963 is adjusted, the focusing lens 964 is aligned with the coating position to ensure the laser beam accurately acts on the drill bit surface, the laser emitter body 963 emits the laser beam → melting the alloy powder and coating it onto the drill bit surface, the laser emitter body 963 is turned off → the motor 51 stops, the clamping plate 57 is released → The machined drill bit is removed, the equipment is reset, and the next workpiece is prepared for processing. This process, through multi-axis coordinated motion, realizes fully automated operation from drill bit clamping to laser coating, significantly improving processing efficiency and coating quality stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
