[0003] Publication No. CN 204058594 U discloses a five-axis linkage laser precision cladding equipment, which can achieve three-axis motion and adjust the angle of the workpiece. However, in the existing technical solution, there is only one processing station, and the existing technical solution cannot enable the laser cladding head to achieve complex trajectory movements. Therefore, the existing technical solution cannot clad an entire set of wear-resistant workpieces in one go, resulting in low processing efficiency of the equipment, and also requiring operators to frequently change workpieces, affecting the processing efficiency of the product.

[0025] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0026] The technical solution is explained below. In the existing solution, there is only one processing station. During laser cladding, the equipment cannot clad an entire set of parts at once, resulting in a low processing speed. Furthermore, operators need to frequently change workpieces, further impacting product processing speed. Therefore, if… Figure 1 and Figure 2 As shown, this utility model provides a laser cladding device for wear-resistant parts of a tunneling machine gun head, comprising: Equipment body 1; Laser cladding component 2 is mounted on the main body 1 of the equipment; At least two adjustable components 3 are disposed on the main body 1 of the equipment for clamping the rotating workpieces 100 and maintaining or adjusting the posture of at least two rotating workpieces 100 relative to the main body 1 of the equipment; The receiving component 4 is installed on the main body 1 of the equipment and is used to receive flat workpieces; The laser cladding component 2 is movable relative to the main body 1 of the equipment and is used to sequentially perform laser cladding on at least two rotating workpieces 100 and a planar workpiece.

[0027] At least two adjustable components 3 and one receiving component 4 are provided on the main body 1 of the equipment. Therefore, at least three workpieces can be stored inside the main body 1 at one time. In this way, the laser cladding component 2 can process at least three workpieces in one start-up process.

[0028] More specifically, on the tunnel boring machine's gun head, laser cladding is required on the cutting teeth, tooth holders, and wear-resistant blocks to enhance their wear resistance. The cutting teeth and tooth holders are rotating parts, and the cutting teeth also possess characteristics such as... Figure 2 The conical inclined surface shown has the cutting teeth and tooth holder fixed on the corresponding adjustable component 3, while the wear-resistant block is placed on the top surface of the receiving component 4. In a single laser cladding process, multiple workpieces can be clad continuously in sequence, which greatly improves the cladding efficiency of the product.

[0029] To stably adjust the posture of the rotating workpiece 100, at least two adjustable components 3 each include: The base 31 is mounted on the main body 1 of the equipment; Adjustable component 32 is set on base 31 and can rotate along the axial center line a of the rotating workpiece 100 and the straight line b parallel to the width direction of the main body 1 of the equipment, so as to maintain or adjust the posture of the rotating workpiece 100 at multiple angles. The clamping component 33 is mounted on the adjustable component 32 and is used to fix the rotating workpiece 100.

[0030] like Figure 2 and Figure 3As shown, when the rotating workpiece 100 is fixed on the clamping member 33, the pitch angle of the rotating workpiece 100 relative to the main body of the equipment is first adjusted by the adjustable member 32 with the straight line b as the axis, and then the angle of the rotating workpiece 100 relative to the laser cladding assembly 2 is adjusted by the adjustable member 32 with the axial center line a as the axis, thereby completing the adjustment of the posture of the rotating workpiece 100.

[0031] Adjustable component 32 includes: The first rotating unit 321 is mounted on the base 31 and is used to adjust the pitch angle of the axial center line of the rotating workpiece 100 relative to the main body of the equipment 1. The second rotating unit 322 is disposed on the output shaft of the first rotating unit 321. A clamping member 33 is disposed on the output end of the second rotating unit 322 for driving the rotating workpiece 100 to rotate synchronously with the output shaft of the second rotating unit 322.

[0032] Specifically, the rotation axis of the output shaft of the first rotating unit 321 is collinear with the straight line b, and the output shaft of the second rotating unit 322 is collinear with the axial center line a. When the first rotating unit 321 rotates, the pitch angle of the second rotating unit 322 and the clamping member 33 relative to the main body 1 of the equipment can be adjusted. When the output shaft of the second rotating unit 322 rotates, the position of the rotating workpiece 100 relative to the laser cladding assembly 2 can be adjusted, so that the laser cladding assembly 2 can perform laser cladding on the circumferential side surface of the rotating workpiece 100.

[0033] In order to save internal space of the main body 1, the adjustable component 32 also includes a rotating component 323. The rotating component 323 is provided with a through first rotating groove 3201. The outline of the first rotating groove 3201 is adapted to the outline of the second rotating unit 322. The second rotating unit 322 is disposed in the first rotating groove 3201. A through second rotary groove 3101 is provided on the base 31. The outline of the second rotary groove 3101 is adapted to the outline of the rotary component 323. The rotary component 323 is rotatably disposed in the second rotary groove 3101 and connected to the output end of the first rotating unit 321.

[0034] like Figure 2 and Figure 3 As shown, the rotating component 323 is rotatably connected to the base 31 with the slot opening facing the base 31, and the second rotating unit 322 is installed inside the first rotating slot 3201. In this way, the second rotating unit 322 rotates directly within the base 31, and the output shaft of the second rotating unit 322 passes through the first rotating slot 3201 and extends to the other side of the rotating component 323, and is used to fix the clamping component 33. While ensuring stable adjustment of the angle of the clamping component 33, it also improves the compactness of the structure and ensures that it does not occupy too much space.

[0035] like Figure 2 and Figure 3 As shown, to avoid collisions due to excessive angle adjustment, the adjustable member 32 also includes: The limiting member 324 is disposed on the base 31 and located in the second rotary groove 3101, and is used to limit the pitch angle of the first rotating unit 321 adjusting the rotating workpiece 100.

[0036] Specifically, the limiting member 324 is configured as a limiting rod, which is set in the second rotary groove 3101 along the width direction of the main body 1 of the equipment, and blocks the second rotating unit 322 by limiting the first rotating unit 321 to adjust the pitch angle of the rotating workpiece 100.

[0037] It should be noted that the limiting rod described here is only one embodiment. The limiting rod can also be configured as a limiting block, limiting bolt, or other structure disposed in the second rotary groove 3101. Therefore, it should not be construed as a limitation on the embodiment of this utility model. In order to effectively clamp the rotating workpiece 100, the clamping member 33 is configured as a three-jaw chuck for circumferentially clamping the rotating workpiece 100 at different positions; wherein, the three-jaw chuck can effectively clamp different positions on the outer wall of the rotating workpiece 100.

[0038] To effectively laser clad workpieces at multiple workstations, the laser cladding assembly 2 includes: The three-axis adjustment component 21 is installed on the equipment body 1 and is used to move relative to the length, height and width of the equipment body 1. The laser cladding component 22 is mounted on the triaxial control component 21.

[0039] The laser cladding component 22 moves inside the main body 1 of the equipment via the triaxial control component 21, thereby enabling laser cladding of workpieces at different positions.

[0040] The three-axis adjustment component 21 includes: The first linear unit 211 is disposed on the equipment body 1 and is used to move relative to the length direction of the equipment body 1; The second linear unit 212 is disposed at the output end of the first linear unit 211 and is used to move relative to the width direction of the device body 1. The third linear unit 213 is located at the output end of the second linear unit 212. The output end of the third linear unit 213 is provided with a laser cladding component 22, which is used to move relative to the height direction of the main body 1 of the equipment.

[0041] The first linear unit 211, the second linear unit 212, and the third linear unit 213 are all configured as motor screw structures. The use of motor screw structures can accurately control the distance between the laser cladding component 22 and the rotating workpiece 100, thereby ensuring that the rotating workpiece 100 is accurately laser clad.

[0042] like Figure 1 and Figure 5 As shown, the main body of the equipment 1 has a cavity 101. The laser cladding component 22, at least two adjustable components 3 and the receiving component 4 are all located in the cavity 101. Several sliding doors 11 are provided at the opening of the cavity 101. The several sliding doors 11 are arranged sequentially along the length direction of the main body of the equipment 1 and correspond to the positions of at least two adjustable components 3 and receiving components 4 respectively.

[0043] When the laser cladding assembly 2 processes multiple workpieces, since the main body 1 of the equipment is equipped with multiple sliding doors 11, and each workpiece has its corresponding sliding door 11, the sliding doors 11 can not only enable the corresponding workpieces to be picked up normally, but also protect the arc light generated during the operation of the laser cladding assembly 2, so as to avoid damage to the operator's eyes from the bright light, improve the protection of the equipment for the operator, and ensure the safety of the operator.

[0044] After the workpiece is laser cladding completed, the corresponding sliding door 11 can be opened to take out the laser cladding workpiece, thereby further improving the continuity of the laser cladding assembly 2, enabling the laser cladding assembly 2 to work uninterruptedly, and avoiding the time wasted by frequent start-stop of the laser cladding assembly 2.

[0045] Specifically, to ensure that at least two adjustable components 3 and the receiving component 4 do not interfere with each other spatially, the receiving component 4 is located between at least two adjustable components 3 and close to several sliding doors 11. Taking two adjustable components 3 as an example, the two adjustable components 3 and the receiving component 4 are arranged in a triangle, with the receiving component 4 located at the top corner and the two adjustable components 3 located at the two bottom corners.

[0046] like Figure 6 and Figure 7The diagram shows a schematic of a coal mining machine's blasting head. The rotating workpiece 100 is specifically configured with a cutting tooth 110 and a tooth holder 120. The cutting tooth 110 is the "frontline rock-breaking tool," directly facing strong coal seam impact wear. Therefore, a wear-resistant area is laser-clad on the conical inclined surface at the front end of the cutting tooth 110. The tooth holder 120 is the "load-bearing connector," mainly bearing fretting wear and impact fatigue. Therefore, a wear-resistant area is laser-clad on the circumferential side of the tooth holder 120. The wear-resistant block 200 located at the root of the blasting head is the "blasting head guardian," resisting strong extrusion and sliding wear. Complex wear-resistant patterns need to be clad on the surface of the wear-resistant block 200. The planar wear-resistant patterns are formed by laser cladding of the laser cladding component 22 relative to the surface of the wear-resistant block 200, controlled by CNC programming.

[0047] like Figure 6 As shown, the working principle of the laser cladding device for wear-resistant parts of the tunneling machine head is as follows: The cutting teeth 110, tooth holders 120, and wear-resistant blocks 200 that need to be pre-strengthened are installed on the corresponding workstations. After the workpiece positions are adjusted, the laser cladding component 22 can simultaneously complete the surface wear-resistant laser cladding of the cutting teeth 110, tooth holders 120, and wear-resistant blocks 200 in a relatively enclosed environment. In one start-up process, a set of wear-resistant workpieces can be laser clad. The laser cladding device for wear-resistant parts of the tunneling machine head has the advantages of multiple workstations and full functionality. It also covers the wear-resistant surface of the cutting teeth 110 (i.e., the conical surface), the wear-resistant surface of the tooth holders 120 (i.e., the curved arc surface), and the complex planar wear-resistant trajectory of the wear-resistant blocks 200. It has good economic efficiency and high efficiency.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
