Description

Technical Field

[0001] This utility model relates to the field of laser cladding head technology, specifically a laser cladding head component. Background Technology

[0002] Currently, with the development of industrial lasers, laser cladding technology has been applied more and more widely. Laser cladding is a process in which cladding material is added to the surface of a substrate, and a high-energy-density laser is used to melt and solidify the powder and form a metallurgically bonded cladding layer with the substrate surface.

[0003] A laser cladding head with patent number CN201921096272.0 has functions such as height and angle adjustment, and can also avoid uneven powder feeding and clogging of the powder feeding port during the powder feeding process, effectively improving powder utilization. However, it still has some defects in actual use, such as the lack of positioning measures for the substrate. This means that the substrate is prone to displacement during subsequent processing, resulting in the processing position not matching the predetermined position and causing waste of substrate. Utility Model Content

[0004] The purpose of this utility model is to provide a laser cladding head component to solve the problem mentioned in the background art. This technical solution can provide positioning measures for the substrate, ensure the stability of the substrate during subsequent processing, and avoid processing misalignment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser cladding head component, including a worktable, a rotating platform is provided on the top of the worktable near the left side, an adjustment component is provided at the bottom of the rotating platform, a telescopic arm is installed on the top of the rotating platform, a laser head is fixedly installed at the bottom of the telescopic arm, a placement plate is fixedly installed on the top of the worktable near the right side, a positioning component is provided on the top of the placement plate near both the front and rear sides, and a limit component is provided on the top of the placement plate near both the left and right sides.

[0006] Preferably, the adjustment component includes a hollow shell, which is fixedly connected to the top of the worktable near the left side. A movable block is movably connected to the inner cavity of the hollow shell. The top of the movable block is fixedly connected to the bottom of the rotary table. A screw is threaded through the movable block. The two ends of the screw penetrate the side wall of the hollow shell and are movably connected to the side wall of the hollow shell. A servo motor is fixedly connected to the front end of the screw. The servo motor is fixedly installed on the outer wall of the hollow shell.

[0007] Preferably, the positioning component includes two side blocks, which are fixedly connected to the front and rear sides of the placement plate, respectively. A transverse groove is provided on the placement plate, and a second screw is provided in the inner cavity of the transverse groove. The two ends of the second screw pass through the corresponding side blocks and are movably connected to the corresponding side blocks. Two threaded sleeves are threadedly connected to the outer side of the second screw. A connecting block is fixedly connected to the top of each of the two threaded sleeves, and a clamping plate is fixedly connected to each of the two connecting blocks.

[0008] Preferably, the limiting component includes two limiting plates, which are respectively located on the top of the placement plate near the left and right sides. A connecting strip is fixedly connected to the side of the two limiting plates that is far apart from each other. A limiting block is fixedly connected to the bottom of each of the two connecting strips. A side groove is opened on the top of the placement plate near the left and right sides. The limiting block is slidably connected to the inner cavity of the corresponding side groove, and a spring is fixedly connected between the outer wall of the limiting block and the inner wall of the corresponding side groove.

[0009] Preferably, both ends of the second screw are fixedly connected to handwheels.

[0011] Preferably, four bases are fixedly connected to the bottom of the workbench, and the four bases are located at the four corners of the bottom of the workbench.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting springs, limiting plates, and limiting blocks, before placing the substrate on top of the placement plate, the two limiting plates can be moved relative to each other, so that the two limiting plates push the limiting blocks on the corresponding connecting strips to move. The limiting blocks stretch the springs inside the corresponding side grooves. Then, the substrate is placed between the two limiting plates, and the two limiting plates are released, so that the two limiting plates return to the center under the elastic force of the corresponding springs, clamping the left and right sides of the substrate, thus achieving the initial positioning of the substrate.

[0014] 2. With clamping plates, a second screw, and a handwheel, after the substrate is initially positioned, the handwheel on the front or rear side can be rotated, causing the second screw to rotate. The second screw then moves the two threaded sleeves on it relative to each other. The two threaded sleeves move the corresponding connecting blocks, and the connecting blocks move the corresponding clamping plates. The relative movement of the two clamping plates clamps and positions the front and rear sides of the substrate, ensuring that the substrate will not move during subsequent processing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a laser cladding head component, including a worktable 1, a rotating platform 7 is provided on the top of the worktable 1 near the left side, an adjustment component is provided at the bottom of the rotating platform 7, a telescopic arm 8 is installed on the top of the rotating platform 7, a laser head 9 is fixedly installed at the bottom of the telescopic arm 8, a placement plate 10 is fixedly installed on the top of the worktable 1 near the right side, a positioning component is provided on the top of the placement plate 10 near the front and rear sides, and a limit component is provided on the top of the placement plate 10 near the left and right sides.

[0022] The adjustment component is used to adjust the position of the rotary table 7 to achieve the purpose of large-scale processing. The telescopic arm 8, in cooperation with the rotary table 7, can move the laser head 9 to various positions for subsequent processing, increasing the processing range. The positioning component is used to position the substrate on the top of the placement plate 10, improving the stability of subsequent processing. The setting of the limiting component can initially limit the substrate, making it convenient to position the substrate without manual assistance from the staff.

[0023] Please see Figure 1 and Figure 2The adjustment component includes a hollow shell 3, which is fixedly connected to the top of the worktable 1 near the left side. A movable block 6 is movably connected to the inner cavity of the hollow shell 3. The top of the movable block 6 is fixedly connected to the bottom of the rotary table 7. A screw 5 is threaded through the movable block 6. The two ends of the screw 5 pass through the side wall of the hollow shell 3 and are movably connected to the side wall of the hollow shell 3. A servo motor 4 is fixedly connected to the front end of the screw 5. The servo motor 4 is fixedly installed on the outer wall of the hollow shell 3.

[0024] In this process, the servo motor 4 drives the first screw 5 to rotate, and the first screw 5 drives the movable block 6 to move repeatedly inside the shell 3. This causes the movable block 6 to drive the top rotary table 7 to move repeatedly, adjusting the telescopic arm 8 and the laser head 9 on the rotary table 7 to achieve the purpose of adjusting the processing position.

[0025] Please see Figure 3 and Figure 4 The positioning component includes two side blocks 18, which are fixedly connected to the front and rear sides of the placement plate 10 respectively. The placement plate 10 has a horizontal groove 16, and a second screw 17 is provided in the inner cavity of the horizontal groove 16. The two ends of the second screw 17 pass through the corresponding side blocks 18 and are movably connected to the corresponding side blocks 18. Two threaded sleeves 20 are threadedly connected to the outer side of the second screw 17. A connecting block 21 is fixedly connected to the top of each of the two threaded sleeves 20, and a clamping plate 22 is fixedly connected to each of the two connecting blocks 21.

[0026] The rotation of the second screw 17 drives the two threaded sleeves 20 to move relative to each other. The two threaded sleeves 20 respectively drive the clamping plates 22 on the corresponding connecting blocks 21 to move. The relative movement of the two clamping plates 22 achieves the clamping and positioning of the substrate.

[0027] Please see Figure 3 and Figure 4 The limiting component includes two limiting plates 15, which are located on the top of the placement plate 10 near the left and right sides respectively. Each of the two limiting plates 15 is fixedly connected to a connecting strip 14 on the side away from each other. Each of the two connecting strips 14 is fixedly connected to a limiting block 12 at the bottom. Each of the top of the placement plate 10 near the left and right sides has a side groove 11. The limiting block 12 is slidably connected to the inner cavity of the corresponding side groove 11, and a spring 13 is fixedly connected between the outer wall of the limiting block 12 and the inner wall of the corresponding side groove 11.

[0028] In this method, the spring 13 applies elastic force to the limiting block 12, so that the connecting strip 14 and the limiting plate 15 on the limiting block 12 can apply clamping force to the outer wall of the substrate, and initially stabilize the substrate on the top surface of the placement plate 10. This eliminates the need for manual support from staff in subsequent positioning work, which improves convenience and eliminates safety hazards.

[0029] Please see Figure 3 and Figure 4Both ends of the second screw 17 are fixedly connected to handwheels 19.

[0030] The two handwheels 19 allow workers to easily apply force, enabling the No. 2 screw 17 to smoothly drive the threaded sleeve 20 and other components on it to move.

[0031] Please see Figure 4 The screw No. 2, 17, has its front and rear threads arranged in opposite directions with its side wall center axis as the axis of symmetry.

[0032] The above description allows the second screw 17 to rotate smoothly, driving the two threaded sleeves 20 to move in opposite directions, ensuring that the positioning of the substrate can be carried out smoothly.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the workbench 1 is fixedly connected to four bases 2, which are located at the four corners of the bottom of the workbench 1.

[0034] The four bases 2 provide support to the bottom of the workbench 1, and their distributed arrangement ensures the stability of the workbench 1 to a certain extent.

[0035] Working principle: When using this application, firstly, the two limiting plates 15 are moved relative to each other, so that the two limiting plates 15 push the limiting blocks 12 on the corresponding connecting strips 14 to move. The limiting blocks 12 stretch the springs 13 inside the corresponding side grooves 11. Then, the substrate is placed between the two limiting plates 15 and the two limiting plates 15 are released, so that the two limiting plates 15 return to the center under the elastic force of the corresponding springs 13, clamping the left and right sides of the substrate to achieve the initial positioning of the substrate. Then, the handwheel 19 on the front or rear side is rotated, so that the handwheel 19 drives the second screw 17 to rotate. The second screw 17 drives the two threaded sleeves 20 on it to move relative to each other. The two threaded sleeves 20 drive the corresponding connecting blocks 21 to move respectively. The connecting blocks 21 drive the corresponding clamping plates 22 to move. The relative movement of the two clamping plates 22 clamps and positions the front and rear sides of the substrate to ensure that the substrate will not move during subsequent processing.

[0036] Then, laser head 9 is used to perform laser welding on the substrate. If the position of laser head 9 needs to be adjusted during the welding process, the position of laser head 9 can be adjusted by the cooperation of rotary table 7 and telescopic arm 8. If there is a position that laser head 9 cannot reach, servo motor 4 is driven, which drives the movable block 6 on screw 5 to move. Movable block 6 drives the top rotary table 7, telescopic arm 8 and laser head 9 to move. After moving to the appropriate position, the rotary table 7 and telescopic arm 8 are used to achieve the effect of moving laser head 9 over a wide range, ensuring that the work can be completed in various places.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
