Description

Technical Field

[0001] This utility model relates to the field of thermal spraying technology, specifically to a spraying component fixing structure for a thermal spraying rotating frame. Background Technology

[0002] Thermal spraying technology, as an important surface treatment process, forms a coating by atomizing molten spray material through a high-speed airflow and spraying it onto the surface of parts. It is widely used in fields such as machinery manufacturing and aerospace. During thermal spraying, the rotating frame's component fixing structure is a key equipment component that ensures coating uniformity and adhesion strength; its performance directly affects spraying quality and production efficiency.

[0003] Chinese Patent Announcement No. CN223027601U discloses a spraying part fixing device for a thermal spraying rotating frame, relating to the field of thermal spraying. The device includes a support column, with a horizontally welded mounting ring on the outer side of the support column. The top surface of the mounting ring has evenly distributed fixing through holes. An extension rod is vertically inserted into the top of the support column, and the top of the extension rod is horizontally connected to a support plate. A cross-shaped groove is horizontally distributed on the top surface of the support plate, and clamping blocks are evenly connected to it. An adjusting cylinder is vertically fixed to the inner side of the support column. A mounting ring is horizontally welded to the outer side of the extension rod, and a transmission motor is fixed to the inner wall of the extension rod. The bottom surface of the support plate has evenly distributed mounting screw holes. The device employs a telescopic adjustment structure, allowing adjustment to a specified height. Furthermore, the rotating clamping and multi-angle clamping structure makes clamping more stable and efficient.

[0004] In the prior art, during the use of a spraying part fixing device for a thermal spraying rotating frame, the atomized paint generated during the spraying process will directly splash into the external environment, which not only pollutes the equipment, the ground and other surrounding areas, but also wastes paint. At the same time, the exhaust gas generated by thermal spraying has no collection path and will directly diffuse into the work space, making it impossible to avoid the exhaust gas from harming the health of workers. Therefore, we have made improvements to this and proposed a spraying part fixing structure for a thermal spraying rotating frame. Utility Model Content

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3, a spraying component fixing structure for a thermal spraying rotating frame, comprising a base 1, a support rod 2 fixedly mounted on the top of the base 1, a rotating ring 4 disposed on the top of the base 1, the rotating ring 4 being inserted into the interior of the base 1 and rotatably connected thereto, the inner diameter of the rotating ring 4 being larger than the outer diameter of the support rod 2, a base 3 fixedly mounted on the top of the rotating ring 4, the support rod 2 passing through the base 3 and slidably connected thereto, a sealing ring being embedded on the support rod 2 at the junction of the support rod 2 and the base 3, a top plate 5 disposed on the top of the support rod 2, an annular protective cover 6 fixedly mounted on the bottom of the top plate 5, and several placement plates 8 disposed on the top of the base 3, and... The placement plate 8 is inserted into the base 3 and slidably connected to it. The annular protective cover 6 is slidably connected to the base 3 and several placement plates 8. Each of the several placement plates 8 is provided with a fixing structure. A U-shaped fixing tube 13 is fixedly installed inside the top plate 5. Several conical heads 15 are fixedly installed at the bottom of the U-shaped fixing tube 13. The several conical heads 15 pass through the bottom of the top plate 5 and are fixedly connected to it. An output tube 14 is fixedly installed on one side of the U-shaped fixing tube 13, and the output tube 14 passes through one side of the top plate 5 and is fixedly connected to it. A connecting groove is opened on the U-shaped fixing tube 13 to cooperate with the output tube 14 and several conical heads 15.

[0031] In this embodiment of the utility model, the base 1 serves as the load-bearing foundation of the entire structure. The support rod 2 fixedly installed on its top provides vertical support for the top plate 5. At the same time, the rotating ring 4 is inserted into the base 1 and rotatably connected to the base 1. The inner diameter of the rotating ring 4 is larger than the outer diameter of the support rod 2 to avoid interference between the rotating ring 4 and the support rod 2 when rotating. The base 3 fixed on the top of the rotating ring 4 can rotate synchronously with the rotating ring 4. The support rod 2 passes through the base 3 and is slidably connected to the base 3. The sealing ring embedded at the junction of the two can prevent impurities from entering the junction gap during the spraying process and ensure the smooth rotation of the base 3.

[0032] The annular protective cover 6 fixed at the bottom of the top plate 5 can partially cover the base 3 and the placement plate 8, reducing the impact of paint splashing on the external environment during the spraying process. Several placement plates 8 slidably connected to the top of the base 3 are used to place the parts to be sprayed, and the annular protective cover 6 is slidably connected to the base 3 and the placement plates 8, without affecting the normal movement of the base 3 and the placement plates 8. The fixing structure set on the placement plate 8 can clamp and fix the parts to be sprayed, preventing the parts from shifting during the spraying process and ensuring the spraying accuracy.

[0033] The U-shaped fixing tube 13 fixed inside the top plate 5 has several conical heads 15 fixed at its bottom that pass through the bottom of the top plate 5 and can be close to the area to be sprayed. The output tube 14 on one side of the U-shaped fixing tube 13 passes through one side of the top plate 5. When in use, the output tube 14 can be connected to an external negative pressure device. During the spraying process, the external negative pressure device is activated, and negative pressure is generated in the U-shaped fixing tube 13 through the output tube 14. The connecting groove on the U-shaped fixing tube 13 that matches the output tube 14 and the conical heads 15 allows the negative pressure to be transmitted to each conical head 15. The conical heads 15 can absorb the exhaust gas and excess atomized paint generated during the spraying process, preventing the diffusion of exhaust gas and the random dripping of excess paint, improving the working environment and reducing paint waste.

[0034] In this embodiment of the invention, the cooperation of the base 1, support rod 2, rotating ring 4, and base 3 not only achieves stable rotation of the base 3, but also ensures the sealing of the component connections through the sealing ring, reducing impurity interference and extending the service life of the equipment; the annular protective cover 6 effectively reduces paint splashing; the adsorption structure composed of the U-shaped fixing tube 13, the conical head 15, and the output tube 14 can efficiently absorb spraying exhaust gas and excess paint, improve the working environment, reduce paint waste, and meet environmental protection requirements; several placement plates 8 can support multiple sprayed parts, and the fixed structure can ensure that the sprayed parts do not shift during the spraying process, ensuring spraying accuracy, and is suitable for batch spraying operations.

[0035] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -4. As a preferred embodiment of this utility model, a cross-shaped insert plate 7 is fixedly installed at the bottom of the top plate 5. The cross-shaped insert plate 7 is inserted into the support rod 2 and slidably connected to it. A pump is provided on one side of the top plate 5 and on the output pipe 14. A spraying groove 10 and two through grooves 9 are provided on the annular protective cover 6. The two through grooves 9 are the feeding groove and the unloading groove, respectively. There are four placement plates 8. The spraying groove 10 and the two through grooves 9 are all provided on one side of the placement plate 8. A U-shaped fixing pipe 13 is provided on the top of one of the placement plates 8.

[0036] A first servo motor 11 is fixedly installed inside the base 1. A gear 12 is fixedly installed at the output end of the first servo motor 11. The gear 12 is rotatably connected to the base 1. Several teeth are fixedly installed at the bottom of the outer side of the rotating ring 4. The gear 12 meshes with the several teeth, and the several teeth are rotatably connected to the base 1.

[0037] The fixed structure includes a side plate 16, which is fixedly installed on the top of the placement plate 8. Two clamping plates 19 are provided on one side of the side plate 16 and above the placement plate 8. Both clamping plates 19 are inserted into the interior of the side plate 16 and slidably connected thereto. A bidirectional lead screw 18 is rotatably connected inside the side plate 16. The bidirectional lead screw 18 passes through the two clamping plates 19 and is threadedly connected thereto. A second servo motor 20 is fixedly installed inside the side plate 16. A worm gear 21 is fixedly installed at the output end of the second servo motor 20. A worm wheel meshes with the outer side of the worm gear 21 and is fixedly installed on the outer side of the bidirectional lead screw 18. Both the worm gear 21 and the worm wheel are rotatably connected to the side plate 16.

[0038] Several through-hole plates 17 are fixedly installed on the corresponding sides of several placement plates 8. Several through-hole plates 17 are inserted into the interior of the base 3 and slidably connected thereto. Several through-hole plates 17 are provided with fixing screws on their tops. Several fixing screws pass through several through-hole plates 17 and are threadedly connected thereto. Several fixing bolts are inserted into the interior of the base 3 and are threadedly connected thereto.

[0039] A controller 22 is embedded on one side of the base 1. The controller 22 is electrically connected to the pump, the first servo motor 11 and several second servo motors 20. One-way valves are provided at the bottom of the top plate 5 and on several conical heads 15.

[0040] In this embodiment of the utility model, the cross-shaped insert 7 fixed at the bottom of the top plate 5 is inserted into the support rod 2 to connect the top plate 5 and the annular protective cover 6 with the support rod 2, which facilitates quick disassembly and cleaning; the pump on one side of the top plate 5 and located on the output pipe 14 can enhance the negative pressure suction in the U-shaped fixed pipe 13. If there is a lot of waste gas and excess paint during the spraying process, starting the pump can improve the adsorption efficiency and ensure effective treatment of waste gas and excess paint.

[0041] The spraying groove 10 on the annular protective cover 6 provides an operating channel for the nozzle of the external spraying equipment, facilitating the spraying operation of the workpiece to be sprayed through the spraying groove 10. The two through grooves 9 serve as the loading groove and unloading groove, respectively. The operator can place the workpiece to be sprayed on the placement plate 8 through the loading groove and remove the sprayed workpiece from the placement plate 8 through the unloading groove, realizing the orderly process of loading, spraying, and unloading, and avoiding the impact on work efficiency due to frequent disassembly of the protective cover. There are four placement plates 8, and the spraying groove 10 and the two through grooves 9 are all located on one side of the placement plate 8, ensuring that the workpiece to be sprayed can be sprayed through the spraying groove 10 after each placement plate 8 is rotated, while facilitating loading and unloading through the two through grooves 9. The U-shaped fixing tube 13 is located on the top of one of the placement plates 8, which can specifically adsorb the exhaust gas and excess paint generated during the spraying process on the placement plate 8 without a groove on one side. By cooperating with the rotation of the base 3, the adsorption of spraying operations on different placement plates 8 can be achieved alternately.

[0042] The first servo motor 11, fixed inside the base 1, provides power for the rotation of the rotating ring 4. When the first servo motor 11 is started, its output end drives the gear 12 to rotate. Since the gear 12 meshes with several teeth fixed to the bottom of the outer side of the rotating ring 4, and the teeth are rotatably connected to the base 1, the rotation of the gear 12 will drive the rotating ring 4 to rotate around the central axis of the base 1, thereby driving the base 3 and the placement plate 8 on the top of the rotating ring 4 to rotate synchronously. The first servo motor 11 can achieve precise speed adjustment and fixed angle rotation through the controller 22. It can adjust the rotation speed of the base 3 according to the spraying requirements. For example, the speed can be reduced during fine spraying to ensure uniform spraying. It can also control the base 3 to rotate at a specific angle so that different placement plates 8 are aligned with the spraying tank 10 in sequence, realizing multi-station continuous spraying and improving work efficiency.

[0043] In this embodiment of the utility model, the side plate 16 in the fixing structure is fixed to the top of the placement plate 8, providing initial constraint for the subsequent clamping components; after the second servo motor 20 fixed inside the side plate 16 is started, it drives the worm 21 at its output end to rotate. Since the worm 21 meshes with the worm wheel fixed on the outside of the bidirectional lead screw 18, and the worm 21, worm wheel, and bidirectional lead screw 18 are all rotatably connected to the side plate 16, the rotation of the worm 21 will drive the worm wheel and the bidirectional lead screw 18 to rotate synchronously; the bidirectional lead screw 18 passes through the two clamping plates 19 and is threadedly connected to them. When the bidirectional lead screw 18 rotates, the two clamping plates 19 slide along the inside of the side plate 16 and move closer or further apart due to the opposite direction of the threads at both ends. When the part to be sprayed is placed between the two clamping plates 19, the second servo motor 20 is controlled to drive the bidirectional lead screw 18 to rotate in the forward direction, and the two clamping plates 19 move closer together until the part to be sprayed is clamped and fixed. After the spraying is completed, the second servo motor 20 is controlled to rotate in the reverse direction, and the two clamping plates 19 move further apart, so the part to be sprayed can be removed. This achieves automated clamping and releasing, which is convenient to operate and the clamping force is controllable.

[0044] Several placement plates 8 are inserted into the base 3 and slidably connected to the corresponding through-hole plates 17 fixed on both sides. By pushing the placement plates 8, the through-hole plates 17 can be slid within the base 3, thereby adjusting the position of the placement plates 8 on the base 3 to accommodate different sizes of parts to be sprayed, ensuring that the parts to be sprayed can be accurately aligned with the spraying tank 10. After the position of the placement plates 8 is adjusted to the correct position, the fixing screw is passed through the through-hole plates 17 and threadedly connected to the through-hole plates 17. Then, the fixing screw is inserted into the base 3 and threadedly connected to the base 3. By tightening the fixing screw, the through-hole plates 17 and the base 3 can be fixed, thereby locking the position of the placement plates 8, preventing the placement plates 8 from shifting during the spraying process, and ensuring the stability of the spraying.

[0045] The controller 22 embedded on one side of the base 1 is electrically connected to the pump, the first servo motor 11 and several second servo motors 20. The operator can send control commands to each component through the controller 22, such as controlling the start and stop and speed of the first servo motor 11, the forward and reverse rotation of the second servo motors 20 to achieve the clamping and loosening of the clamping plate 19, and the start and stop of the pump to adjust the adsorption force, etc., to achieve centralized automated control of the entire equipment, reduce the difficulty of operation and improve work efficiency.

[0046] The one-way valves located at the bottom of the top plate 5 and on several conical heads 15 can prevent external air or impurities from entering the U-shaped fixed tube 13 through the conical heads 15 when the negative pressure stops, thus avoiding blockage or contamination inside the U-shaped fixed tube 13. At the same time, it ensures that an effective negative pressure can be quickly formed when the negative pressure adsorption is started again, ensuring that the adsorption function is stable and reliable. In addition, the device is provided with heat dissipation holes that cooperate with the servo motor.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
