[0002] High-velocity oxygen fuel (HVOF) spraying systems are scientific instruments that use a combustion chamber to mix fuel gas and oxygen to generate a supersonic flame, which then sprays powder materials onto the surface of a workpiece to form a high-quality coating. Based on rocket engine combustion design, its technology can achieve particle velocities exceeding 1100 m / s, resulting in coatings with technical characteristics such as a microhardness of HV1450, porosity of less than 10%, and bonding strength greater than 40 MPa. This system has been widely applied in more than 20 industrial sectors, including aerospace, shipbuilding, and petrochemicals.

[0003] For example, a supersonic flame spraying laser positioning device, disclosed in CN216585162U, includes a laser, an upper bracket, and a lower bracket, both mounted on the supersonic flame spraying nozzle and fixedly installed by a fixing component; an adjustment component is disposed on the upper bracket, and the laser is mounted on the upper bracket and its direction is adjusted by the adjustment component. This device is time-saving and labor-saving to operate, and has high accuracy. By providing a supersonic flame spraying laser positioning device, it enables operators to easily and accurately determine the movement path of the spray gun.

[0004] The aforementioned patent proposes that the laser passes through a ring, and its direction can be adjusted by adjusting six adjusting screws. Each adjusting screw has a through hole for easy insertion of a fuse, allowing the adjusting screws to be secured by using a fuse to ensure that the adjusting screws do not loosen while the robotic arm moves the supersonic nozzle, thus maintaining the accuracy of laser positioning. However, in actual use, the adjusting screws are not effectively secured during use, which can lead to loosening and affect the positioning accuracy of the laser, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a supersonic flame spraying laser positioning device to solve the problem mentioned in the background art, where the adjusting screw is not effectively fixed during use, which leads to the screw loosening.

The movable shaft is installed inside the movable hole, and threaded caps are threaded to both ends of the movable shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a supersonic flame spraying laser positioning device. A positioning tube is installed at the bottom center of the pneumatic clamp. The laser can be placed inside the positioning tube. The position indicated by the laser spot is the spraying area. When the pneumatic clamp holds the supersonic flame gun, the two sets of moving plates move closer to each other, and the clamping components move closer to each other to clamp and position the supersonic flame gun.

[0016] 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.

[0017] Example 1: Please refer to Figure 1 , Figure 3 and Figure 4 A supersonic flame spraying laser positioning device includes a positioning structure 1. The positioning structure 1 includes a fixing component 11 and a pneumatic gripper 12 installed at the bottom end of the fixing component 11. Movable plates 13 are installed on both sides of the lower end of the pneumatic gripper 12. A moving component 15 is installed on one side of the moving plate 13, and gripping components 14 are installed on the adjacent sides of the moving plate 13. A positioning tube 16 is installed in the middle of the bottom end of the pneumatic gripper 12. The working principle of the pneumatic gripper 12 is based on the action of air pressure. It uses compressed air to drive mechanical parts to achieve the function of clamping or releasing. The pneumatic cylinder is the core part of the pneumatic gripper; it generates linear motion by controlling the inlet and outlet of compressed air. The piston inside the cylinder moves under the push of air pressure, thereby driving the gripper's jaws to perform clamping or releasing actions. During the clamping process, the pneumatic cylinder maintains the clamping state of the jaws through continuous air pressure. Once air pressure is applied, the piston inside the pneumatic cylinder pushes the gripper to close and maintain the clamping force until the air pressure is released or adjusted.

[0018] The clamping member 14 includes a curved clamping plate 141 and a heat dissipation groove 142 formed on the outer surface of the curved clamping plate 141.

[0019] The movable component 15 includes a side plate 151 and a positioning groove 153 formed on the outer surface of the side plate 151. An L-shaped moving strip 152 is slidably installed on one side of the side plate 151, and a positioning strip 154 ​​is installed on the outer side of the L-shaped moving strip 152. A cylinder B155 is installed on one side of the movable plate 13. The positioning strip 154 ​​is slidably installed inside the positioning groove 153 to limit the angle of the moving L-shaped moving strip 152. The moving end of the cylinder B155 is installed on the inner wall of the L-shaped moving strip 152 to facilitate the adjustment of the length of the movable component 15.

[0020] A connecting block 156 is installed at the lower inner end of the L-shaped moving strip 152. A clamping member 14 is installed on one side of the connecting block 156. The clamping member 14 installed on the side of the moving plate 13 and the connecting block 156 that is close to each other is aligned.

[0021] In this embodiment: A positioning tube 16 is installed at the bottom center of the pneumatic clamp 12. The laser can be placed inside the positioning tube 16. The position indicated by the laser spot is the spraying area. When the pneumatic clamp 12 clamps the supersonic flame gun, the two sets of moving plates 13 move closer to each other, and the clamping members 14 installed on the outside of the moving plates 13 move closer to each other to clamp one end of the supersonic flame gun. The moving plates 13 drive the second set of clamping members 14 to move closer to each other through the side plate 151, L-shaped moving strip 152 and connecting block 156 to clamp and position the supersonic flame gun. The curved clamping plate 141 is a curved plate-shaped component made of high-temperature steel. The outer surface of the curved clamping plate 141 is provided with heat dissipation grooves 142. When clamping the supersonic flame gun, the heat dissipation grooves 142 also facilitate the heat dissipation of the supersonic flame gun. The pneumatic clamp 12 remains stable during clamping and will not loosen or slide, ensuring the tightness of the supersonic flame gun.

[0022] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The fixing component 11 includes a top plate 111 and a threaded hole 112 through the middle of the top plate 111. Connecting strips 121 are installed on both sides of the top end of the pneumatic clamp 12. A movable hole 122 is through the middle of the connecting strip 121. The position of the top plate 111 is fixed by bolts.

[0023] A cylinder A126 is installed at the bottom of the top plate 111, and a hemisphere 127 is installed at the moving end of the cylinder A126. The cylinder A126 is designed to facilitate the adjustment of the clamping angle of the pneumatic gripper 12.

[0024] Connecting bends 123 are installed on both sides of the bottom end of the top plate 111. A movable shaft 124 is movably installed at the middle end of the connecting bend 123. The movable shaft 124 is installed inside the movable hole 122. Threaded caps 125 are threaded to both ends of the movable shaft 124. The threaded caps 125 are located on the outside of the connecting bar 121 to restrict the position of the movable shaft 124.

[0025] In this embodiment: After the supersonic flame gun is held for a period of time, the cylinder B155 operates, which drives the L-shaped moving strip 152 to move. The positioning strip 154 ​​installed on the outer surface of the L-shaped moving strip 152 moves within the positioning groove 153, which facilitates the adjustment of the position of the second set of clamping components 14 by using the L-shaped moving strip 152. This allows the device to clamp the supersonic flame gun while also adjusting the clamping position of the supersonic flame gun, avoiding fatigue damage caused by long-term use. The top plate 111 is fixed in the spraying environment. The moving end of the cylinder A126 faces the top of the pneumatic clamp 12. When the cylinder A126 extends, the pneumatic clamp 12 drives the connecting strip 121 to rotate outside the movable shaft 124, adjusting the clamping angle of the pneumatic clamp 12.
