Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, and in particular to a wear-resistant spraying device. Background Technology

[0002] A thermometer is an instrument for measuring temperature. In places like power plant coal mills and flue gas pipelines, thermometers often have a wear-resistant coating applied to the surface of the thermometer sheath. This wear-resistant material protects the thermometer sheath and extends the thermometer's lifespan.

[0003] Currently, most wear-resistant sprayed products on the market use flame spraying. This involves first heating the thermometer sleeve with oxy-acetylene until a certain temperature is reached (the temperature cannot be measured and is judged by visual inspection and experience), then melting the wear-resistant powder at high temperature and spraying it onto the sleeve surface. However, this spraying method is done manually, resulting in poor coating quality, low efficiency, and energy waste. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] This invention provides a wear-resistant spraying device, see [link to device]. Figures 1-8The system includes a machine tool 100, on which a rotating device 200 is provided on one side for holding and controlling the rotation of the workpiece to be sprayed. On the machine tool 100 and on one side of the rotating device 200, a moving mechanism 300 is provided for moving along the length of the workpiece. A laser 400 is provided at the moving end of the moving mechanism 300, and powder feeding heads 500 are provided on both sides of the laser 400. A first adjusting component 600 is provided on the moving mechanism 300 to align the laser 400 with the workpiece axis vertically. A second adjusting component 700 is provided between the laser 400 and the powder feeding heads 500, controlling the movement of the powder feeding heads 500 in both vertical and horizontal directions. A laser system is installed on the laser 400. During operation, the workpiece to be sprayed is clamped by the rotating device 200. Simultaneously, the laser 400, powder feeding head 500, and the axis of the workpiece to be sprayed are aligned by the first adjusting component 600 and the second adjusting component 700. By synchronously controlling the rotation of the workpiece, the powder feeding head 500 sprays alloy powder onto the workpiece. The laser system enables the workpiece and the alloy powder on it to achieve rapid liquefaction and solidification simultaneously, realizing a metallurgical bonding process. During operation, the moving mechanism 300 controls the laser 400 and the powder feeding head to move at a uniform speed along the length of the workpiece and controls the uniform rotation of the workpiece. Ultimately, a protective or reinforcing layer with a dense and uniform metallographic structure, free of inclusions, pores, and cracks, can be formed on the surface of the workpiece.

[0030] The rotating device 200 includes a mechanical gripper 210 fixed to one end of the machine tool 100 and an abutment component 220 disposed at the other end of the machine tool 100; the mechanical gripper 210 holds one end of the workpiece to be sprayed, and the abutment component 220 abuts against the other end of the workpiece to be sprayed. A rotary motor 230 is provided on the machine tool 100 to drive the mechanical gripper 210 to rotate.

[0031] A limiting groove 110 is formed on the machine tool 100 along the length of the workpiece to be coated; the abutment component 220 includes a base 221, with a limiting block 222 integrally formed on the lower side of the base 221. A first lead screw 223 is rotatably disposed in the limiting groove 110, and the first lead screw 223 is threadedly connected to the limiting block 222. One end of the first lead screw 223 is located outside the machine tool 100 and is connected to a first handle 224. During installation, the first handle 224 is manually controlled to move the limiting block 222 along the length of the first lead screw 223. During the movement, the distance between the mechanical gripper 210 and the limiting block 222 is controlled, thereby adjusting the distance between the mechanical gripper 210 and the limiting block 222, and thus enabling the installation or removal of the workpiece to be coated.

[0032] An adjusting sleeve 225 is fixed to the upper side of the base 221. The adjusting sleeve 225 has radially spaced grooves 2251. An adjusting column 226 is provided inside the adjusting sleeve 225. Sliding blocks 2261 are fixed to the adjusting column 226 on both sides near the grooves 2251. The sliding blocks 2261 are located within the grooves 2251 and are slidably connected to them. Through the sliding blocks 2261 and the grooves 2251, the adjusting column 226 can only move in a straight line.

[0033] Even better, a rotating seat 227 is rotatably connected to the adjusting column 226 at one end near the mechanical gripper 210. An abutment 228 is provided on the rotating seat 227. The shape of the abutment 228 can be determined according to the shape of the workpiece to be coated, and its function is to abut the end of the workpiece; the specific shape is not limited. An opening is formed at the end of the adjusting sleeve 225 near the mechanical gripper 210, through which the abutment 228 passes and abuts against the workpiece to be coated.

[0034] The adjusting column 226 has a threaded hole 2262 at its end away from the mechanical gripper 210. The adjusting sleeve 225 has an end cap 2252 at its end away from the mechanical gripper 210. An adjusting rod 229 is rotatably connected to the end cap 2252. One end of the adjusting rod 229 is located outside the adjusting sleeve 225 and connected to a second handle 2291; the other end is located inside the adjusting sleeve 225 and threadedly connected to the threaded hole 2262. During operation, rotating the second handle 2291 controls the rotation of the inner adjusting rod 229. Because the adjusting rod 229 is threadedly connected to the adjusting sleeve 225, the adjusting sleeve 225 moves linearly during rotation. This allows the rotating seat 227 at its end to move closer to or further away from the workpiece to be coated.

[0035] In use, the first handle 224 is controlled to move the base 221 closer to or further away from the mechanical gripper 210, so that the distance between the mechanical gripper 210 and the rotating seat 227 is close to the length of the workpiece to be coated. Then, the second handle 2291 is controlled to continuously move the rotating seat 227 closer to or further away from the mechanical gripper 210, thereby achieving the clamping of the workpiece to be coated by the abutment 228.

[0036] The moving mechanism 300 includes a support platform 310 fixed to the upper side of the machine tool 100. The support platform 310 has first guide grooves 311 formed on both vertical sides parallel to the length direction of the workpiece to be coated. A movable seat 320 is slidably mounted on the upper side of the support platform 310. Guide arms 321 are integrally formed on both sides of the movable seat 320, and the guide arms 321 are fitted into and slidably connected to the first guide grooves 311. The guide arms 321 and the first guide grooves 311 limit the movement of the movable seat 320, allowing it to move only along the length direction of the guide grooves. The length direction of the guide grooves is parallel to the length direction of the workpiece to be coated.

[0037] A first drive groove 312 is formed on the side of the support platform 310 near the movable seat 320, wherein the length direction of the first drive groove 312 is parallel to the length direction of the guide groove. A first drive screw 330 is rotatably disposed within the first drive groove 312, and the length direction of the first drive screw 330 is parallel to the length direction of the guide groove. A drive motor 340 is disposed on the machine tool 100 at one end of the support platform 310, and the drive motor 340 is connected to the first drive screw 330, driving the first drive screw 330 to rotate forward or reverse. A first drive block 350 is fixed on the movable seat 320 near the support platform 310, the first drive block 350 is located within the first drive groove 312, and the first drive screw 330 is threadedly connected to the first drive block 350. When the first drive screw 330 rotates forward or reverse, it drives the movable seat 320 above it to move linearly.

[0038] The first adjustment component 600 includes a horizontally arranged support plate 610; a second guide groove 322 is provided on the vertical side of the movable seat 320 near the mechanical gripper 210; a second drive groove 323 is provided on the movable seat 320 and between the two sets of second guide grooves 322, and both the second guide groove 322 and the second drive groove 323 are vertically arranged.

[0039] A second drive screw 620 is rotatably mounted within the second drive groove 323. The upper end of the second drive screw 620 is located on the upper side of the movable base 320 and is connected to a third handle 630. A second drive block 640 is fixed to the side of the support plate 610 near the second drive groove 323. The second drive block 640 is located within the second drive groove 323 and is threadedly connected to the second drive screw 620. First guide blocks 650 are respectively mounted on the support plate 610 on both horizontal sides of the second drive block 640. The first guide blocks 650 are fitted into the second guide groove 322. The first guide blocks 650 serve a limiting function. When the third handle 630 controls the second drive screw 620 to rotate, it can drive the support plate 610 to move vertically, thereby adjusting the height of the laser 400 and the powder spraying head.

[0040] A mounting block 660 is provided on the side of the support plate 610 away from the movable base 320, and a laser 400 is mounted on the mounting block 660.

[0041] A guide rail 670 is fixed on the support plate 610. The guide rail 670 is horizontal. A third guide groove 661 is formed on the side of the mounting block 660 near the support plate 610. The mounting block 660 is sleeved on the outside of the guide rail 670 through the third guide groove 661.

[0042] The upper side of the mounting block 660 is threaded with a first adjusting screw 680. The lower end of the first adjusting screw 680 is connected to the third guide groove 661 and abuts against the guide rail 670 inside the third guide groove 661. During adjustment, when the first adjusting screw 680 is separated from the guide rail 670, the guide rail 670 and the mounting block 660 can slide relative to each other. After the position of the laser 400 is adjusted, the first adjusting screw 680 is tightened to press against the guide rail 670, thereby fixing the relative position between the guide rail 670 and the mounting block 660.

[0043] An external threaded section 410 is formed on the outer wall of the laser 400. The second adjustment assembly 700 includes a vertical adjustment sleeve 710 threadedly connected to the external threaded section 410. A horizontal adjustment sleeve 720 is rotatably connected to the lower end of the vertical adjustment sleeve 710, and a powder spraying head is connected to the horizontal adjustment sleeve 720. During operation, the vertical height of the powder spraying head is adjusted by rotating the upper vertical adjustment sleeve 710. This allows the height of the powder spraying head to be adjusted according to different powder weights, thereby controlling the flight time of powders of different weights in the laser beam. This ensures that the powder material can fully melt, thus improving the conditions for laser cladding and enhancing the cladding effect.

[0044] The diameter of the horizontal adjusting sleeve 720 is larger than that of the laser 400, which allows for convenient small-range adjustment of the horizontal distance of the horizontal adjusting sleeve 720 to ensure that the powder output direction of the powder spraying head coincides with the laser direction of the laser 400 and the axial direction of the workpiece to be sprayed.

[0045] The horizontal adjusting sleeve 720 has two second guide blocks 721 at its two ends along the diameter direction on its inner side. A fourth guide groove 420 is formed on the outer side of the laser 400, below the external thread section 410. The fourth guide groove 420 is vertically positioned, with one fourth guide groove 420 at each end along the diameter direction of the laser 400. The second guide blocks 721 are located within the fourth guide groove 420 and slide along its vertical direction. When the vertical adjusting sleeve 710 is rotated, the horizontal adjusting sleeve 720, due to the restriction of the second guide blocks 721, can only move linearly in the vertical direction and will not rotate along the vertical axis. Therefore, the position of the powder spraying head on its upper side can only be adjusted in the vertical direction.

[0046] Furthermore, there is a gap between the bottom of the second guide block 721 and the bottom of the fourth guide groove 420. This allows the horizontal adjusting sleeve 720 to move horizontally, and during the movement, the second guide block 721 remains within the fourth guide groove 420, i.e., it will not disengage from the fourth guide groove 420.

[0047] The lower end of the vertical adjusting sleeve 710 has an integrally formed first limiting ring 711 with an L-shaped cross-section, and a first engaging groove 712 is formed between the first limiting ring 711 and the vertical adjusting sleeve 710. The upper end of the horizontal adjusting sleeve 720 has an integrally formed second limiting ring 722 with an L-shaped cross-section, and a second engaging groove 723 is formed between the second limiting ring 722 and the horizontal adjusting sleeve 720. The upper end of the second limiting ring 722 is fitted into the first engaging groove 712, and the maximum outer diameter of the second limiting ring 722 is smaller than the inner diameter of the second engaging groove 723; the minimum inner diameter of the first limiting ring 711 is larger than the inner diameter of the second engaging groove 723. During operation, due to the action of the first engaging groove 712 and the second engaging groove 723, the horizontal adjusting sleeve 720 can move horizontally a certain distance. Therefore, the horizontal movement of the horizontal adjusting sleeve 720 can be controlled within a certain range, achieving relative adjustment of the horizontal position of the powder spraying head and the laser 400.

[0048] A positioning screw hole 724 is radially formed on the side wall of the horizontal adjusting sleeve 720, and a connecting hole 7211 is formed on the second guide block 721. The positioning screw hole 724 and the connecting hole 7211 are aligned; the inner diameter of the connecting hole 7211 is larger than that of the positioning screw hole 724. A second adjusting screw 725 is threadedly connected to the positioning screw hole 724. One end of the second adjusting screw 725 is located outside the horizontal adjusting sleeve 720, and the other end abuts against the bottom of the fourth guide groove 420. When it is necessary to adjust the horizontal position of the horizontal adjusting sleeve 720, the threaded sections of the two second adjusting screws 725 located in the positioning screw hole 724 are adjusted by rotating the two second adjusting screws 725, thereby controlling the horizontal adjusting sleeve 720 to move a set distance in the horizontal direction.

[0049] The two powder feeding heads 500 are respectively installed on both sides of the linear movement of the horizontal adjusting sleeve 720, that is, on both sides near the two second adjusting screws 725. When the horizontal adjusting sleeve 720 is moved horizontally by controlling the second adjusting screws 725, the horizontal position of the powder feeding heads 500 can be adjusted. Through the above technical solution, the horizontal movement of the powder feeding heads 500 can be controlled, and the horizontal distance between the powder feeding heads 500 and the laser 400 can be adjusted. Through this adjustment, the powder output direction of the two powder feeding heads 500 can be ensured to be symmetrical about the laser 400, so that it can enter the laser beam more evenly, improve the uniformity of spraying the workpiece, and avoid powder waste.

[0050] A first adjusting plate 510 is provided on the side wall of the powder feeding head 500, and two sets of second adjusting plates 520 are spaced apart on the lower side of the horizontal adjusting sleeve 720, located at both ends of the diameter direction of the horizontal adjusting sleeve 720. Mounting holes are provided on the first adjusting plate 510 and the second adjusting plate 520, and locking bolts 530 are passed through the mounting holes to fix the first adjusting plate 510 and the second adjusting plate 520. With this configuration, the angle between the two powder spraying heads and the vertical direction can be adjusted as needed during operation. Simultaneously, in conjunction with the second adjusting component 700, the time it takes for the powder to enter the laser beam and the time it takes for the powder to reach the workpiece during the powder spraying process can be better controlled, thus ensuring sufficient heating and melting of the powder and improving powder utilization. Furthermore, by controlling the distance of the powder in the air during the powder spraying process, the difficulty of laser cladding can be reduced, and the coverage process of the melted powder on the workpiece can be better controlled, improving cladding efficiency.
