Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to a metal surface thermal spraying treatment device. Background Technology

[0002] Thermal spraying technology mainly utilizes various heat sources to heat powdered or filamentous metal or non-metal materials to a molten or semi-molten state. Then, through the flame itself or with the assistance of compressed air, these materials are sprayed at extremely high speeds onto the pre-treated substrate surface to form a firmly bonded coating. This technology has wide applications in aerospace, automobile manufacturing, petrochemical and other fields. In particular, when treating the surface of some metal workpieces, thermal spraying can effectively enhance the wear resistance, corrosion resistance, oxidation resistance and heat resistance of the metal surface.

[0003] When using existing thermal spraying equipment for metal surfaces, taking cylindrical metal workpieces as an example, workers typically use clamping components such as three-jaw chucks to hold the cylindrical workpiece from the outside. This clamping method causes part of the outer wall surface of the cylindrical workpiece to be blocked by the clamping components and cannot be sprayed. As a result, workers need to perform a second spraying before the surface treatment of the metal workpiece can be completed. This prolongs the processing flow of the metal workpiece, increases the processing difficulty of the metal workpiece, and also increases the workload of workers to a certain extent, which is not conducive to the progress of metal surface treatment.

[0024] 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.

[0025] Please see Figure 1-6As shown, a metal surface thermal spraying treatment device includes a base plate 1, a top plate 2 above the base plate 1, and side plates 3 vertically installed on both sides of the bottom of the top plate 2. The bottom of the side plates 3 is connected to the base plate 1. A processing platform 12 is provided above the top plate 2. A lower limit seat 13 is fixedly connected to the horizontal center of the top surface of the processing platform 12. A column 15 is fixedly connected to the top of the lower limit seat 13. An upper limit seat 14 is fixedly connected to the top of the column 15. At least three bidirectional ball screws 16 are provided between the upper limit seat 14 and the lower limit seat 13. The multiple bidirectional ball screws 16 are distributed circumferentially around the column 15. The upper limit seat 14 and lower limit seat 13 are rotatably connected to the upper limit seat 14 and lower limit seat 13 respectively. A vertical rod 4 is provided on one side of the processing platform 12. The bottom end of the vertical rod 4 is connected to the top plate 2. The platform also includes a spraying assembly 8 provided on one side of the vertical rod 4, which can spray paint at high speed onto the outside of the metal workpiece. By providing the spraying assembly 8, thermal spraying can be performed on the metal workpiece after it has been positioned and fixed. A guide groove 5 is provided inside the vertical rod 4. A guide rod 7 is provided inside the guide groove 5. The guide rod 7 is connected to both ends of the inner wall of the guide groove 5. A first moving block 6 is slidably connected to the outside of the guide rod 7. A first moving block 6 is provided on one side of the first moving block 6, which allows the spraying assembly 8 to move along the guide groove. The lifting assembly 9, which slides back and forth on the inner wall, drives the spraying assembly 8 to reciprocate up and down, thus performing thermal spraying on the outer side of the metal workpiece from top to bottom. The inner support assembly 17, located outside the bidirectional ball screw 16, facilitates positioning and fixing the metal workpiece on the top of the processing platform 12. This inner support assembly 17 clamps and fixes the metal workpiece from within, preventing incomplete spraying due to component obstruction and ensuring uniform spraying on the outer wall of the metal workpiece. This eliminates the need for secondary spraying operations, improving the efficiency of metal workpiece surface treatment. The bottom of the processing platform 12... A second cylinder 11 is fixedly connected to the upper part. Inside the second cylinder 11, there is a transmission component 20 that can quickly adjust the inner support component 17. By setting the transmission component 20, the position of the inner support component 17 can be adjusted, which facilitates the loading and unloading of materials. A first cylinder 10 is coaxially provided on the outer side of the second cylinder 11. The bottom of the first cylinder 10 is connected to the top plate 2. An adjustment component 21 is provided on one side of the first cylinder 10 that can switch the spraying position of the metal workpiece. By setting the adjustment component 21, the processing platform 12 can be rotated as a whole, thus realizing the switching of the spraying position of the metal workpiece.

[0026] The spraying assembly 8 includes a first L-shaped plate 81 fixed to one side of the first movable block 6. A thermal spray gun 82 is fixedly installed at the bottom of the first L-shaped plate 81. A through-hole 83 is opened on the top side of the top plate 2. A spray hose 84 is installed inside the through-hole 83. The top end of the spray hose 84 passes through the through-hole 83 and connects to the feed port of the thermal spray gun 82. Figure 1 , Figure 2As shown, in actual use, the paint can be connected to the external paint output port through the spray hose 84 to enter the thermal spray gun 82. Then, the thermal spray gun 82 ejects the paint at high speed to complete the spraying task on the metal.

[0027] The lifting assembly 9 includes a fixed base 91 fixed to one side of the upright 4. A lifting cylinder 92 is fixedly installed at the bottom of the fixed base 91. The top of the lifting cylinder 92 passes through the fixed base 91 and is connected to the first moving block 6. Figure 1 , Figure 2 As shown, the lifting cylinder 92 drives the first moving block 6 to slide back and forth along the inside of the guide groove 5. The first moving block 6 then drives the spraying assembly 8 to move up and down, thus performing thermal spraying on the outside of the metal workpiece from top to bottom.

[0028] The inner support assembly 17 includes a second movable block 171 disposed on the outer sides of both ends of the bidirectional ball screw 16. The second movable block 171 is helically connected to the bidirectional ball screw 16 via a nut. A first U-shaped seat 172 is fixedly installed on one side of the second movable block 171. A connecting rod 173 is rotatably connected inside the first U-shaped seat 172. A clamping plate 175 is provided on the side of the bidirectional ball screw 16 away from the column 15. A second U-shaped seat 174 is fixedly installed on one side of the clamping plate 175. One end of the connecting rod 173 is rotatably connected to the second U-shaped seat 174. Figure 3 , Figure 4 As shown, when it is necessary to position and fix the metal workpiece to be sprayed, the bidirectional ball screw 16 can be used to drive the second moving blocks 171 at both ends to move closer to each other. With the cooperation of the first U-shaped seat 172, the connecting rod 173, and the second U-shaped seat 174, the clamping plate 175 can be moved away from the bidirectional ball screw 16. After the multiple clamping plates 175 have expanded, they will limit and clamp the metal workpiece from the inside. This avoids incomplete spraying of the metal workpiece due to component obstruction and ensures the uniformity of spraying on the outer wall of the metal workpiece. After the thermal spraying treatment of the metal workpiece surface is completed, the bidirectional ball screw 16 can be used to drive the second moving blocks 171 at both ends to move away from each other, thus releasing the limiting clamping of the metal workpiece.

[0029] The second movable block 171 is fixedly connected to a limiting block 19 on one side. A limiting groove 18 corresponding to the limiting block 19 is opened on the outer side of the column 15. The limiting block 19 is located inside the limiting groove 18. Figure 3 , Figure 4 As shown, by setting the limiting block 19 and the limiting groove 18, the second moving block 171 can be limited to prevent it from rotating with the rotation of the bidirectional ball screw 16 and causing displacement failure. On the other hand, the displacement of the second moving block 171 can be made smoother, thus improving the stability of the structure.

[0030] The transmission assembly 20 includes a receiving cavity 201 disposed inside the lower limit seat 13. A bidirectional ball screw 16 extends through the receiving cavity 201 and is fixedly connected to a first transmission shaft 202. The bottom end of the first transmission shaft 202 is rotatably connected to the inner wall of the receiving cavity 201. A first gear 203 is fixedly connected to the outer side of the first transmission shaft 202. A first motor 204 is disposed above the top plate 2 and is fixedly mounted on the bottom of the processing platform 12. The output end of the first motor 204 extends through the receiving cavity 201 and is fixedly connected to a second transmission shaft 206. The top end of the second transmission shaft 206 is rotatably connected to the upper limit seat 14. A second gear 205 is fixedly connected to the outer side of the second transmission shaft 206. One side of the first gear 203 meshes with the second gear 205. Figure 4 , Figure 6 As shown, the first motor 204 drives the second transmission shaft 206 and the second gear 205 to rotate. The second transmission shaft 206 then drives the first transmission shaft 202, the first gear 203, and the bidirectional ball screw 16 to rotate through the second gear 205. This causes multiple clamping plates 175 to expand or contract synchronously, which is beneficial for the loading and unloading of metal workpieces.

[0031] The top plate 2 has an opening 22 at its top, and a support base 23 is located inside the opening 22. The top of the support base 23 is connected to the first motor 204. A third slider 25 is fixedly connected to the outside of the support base 23. A third groove 24 corresponding to the third slider 25 is opened on the inner wall of the opening 22. The third slider 25 is located inside the third groove 24. A third drive shaft 26 is vertically mounted at the bottom of the support base 23. A conductive slip ring 27 is provided on the outside of the third drive shaft 26. A second L-shaped plate 28 is fixedly connected to both sides of the stator of the conductive slip ring 27. One end of the second L-shaped plate 28 is connected to the top plate 2. The rotor of the conductive slip ring 27 is connected to the third drive shaft 26. The first motor 204 is connected to the rotor terminal of the conductive slip ring 27 through a wire. Figure 4 As shown, when the processing platform 12 rotates as a whole, the support base 23 at the bottom of the first motor 204 will rotate together with the third transmission shaft 26 and the rotor end of the conductive slip ring 27. The stator end of the conductive slip ring 27 is fixed to the top plate 2 through the second L-shaped plate 28, thus preventing the wires supplying power to the first motor 204 from being torn off due to excessive rotation, and ensuring accurate transmission of current during rotation.

[0032] The adjusting assembly 21 includes a second motor 211 disposed on one side of the first cylinder 10. The second motor 211 is fixedly mounted on the top of the top plate 2. A third gear 212 is fixedly connected to the output end of the second motor 211. An external gear ring 213 is fixedly connected to the top of the second cylinder 11. One side of the third gear 212 meshes with the external gear ring 213. A second slider 215 is fixedly connected to the outer side of the second cylinder 11. A second groove 214 corresponding to the second slider 215 is formed on the inner wall of the first cylinder 10. The second slider 215 is located inside the second groove 214. Figure 4 , Figure 5 As shown, the second motor 211 is driven to rotate, and the second motor 211 then drives the processing platform 12 to rotate as a whole through the external gear ring 213. This completes the switching of the spraying position of the metal workpiece. With the help of the lifting component 9, the outer side of the metal workpiece can be completely sprayed.

[0033] Working principle: First, the operator can clamp and limit the metal workpiece from inside through the transmission component 20 and the inner support component 17, so that the metal workpiece is positioned and fixed on the top of the processing platform 12. This avoids incomplete spraying of the metal workpiece caused by the obstruction of the components, ensures the uniformity of the spraying on the outer wall of the metal workpiece, and helps to improve the surface treatment efficiency of the metal workpiece. Then, the lifting component 9 drives the spraying component 8 to reciprocate up and down, so that the outer side of the metal workpiece can be thermally sprayed from top to bottom. In addition, the adjustment component 21 drives the processing platform 12 to rotate as a whole, so that the spraying position of the metal workpiece can be switched, thus realizing the complete spraying of the outer side of the metal workpiece.
