Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material surface treatment, and in particular to a plasma spraying device based on corrosion-resistant surface treatment of a bolt sleeve. BACKGROUND

[0002] In the current process of rapid development of science and technology, advanced non-ferrous materials are widely used in many key fields due to their excellent properties such as high strength, low density, excellent electrical conductivity and thermal conductivity. In the field of aerospace, aircraft engine parts and fuselage structural parts are largely made of advanced non-ferrous materials such as titanium alloys. The bolt sleeve, as a key component for connection and fastening, is crucial to ensuring the stability of the overall structure of the aircraft, and its quality directly affects flight safety. In the field of electronic information, electronic component heat sinks and circuit boards made of copper alloys and aluminum alloys are efficiently assembled and fixed with the help of bolt sleeves to ensure stable operation of electronic equipment. In the automotive manufacturing industry, the assembly of key parts such as engines and chassis also relies on bolt sleeves made of advanced non-ferrous materials, which need to maintain reliable connection performance under complex mechanical stress and environmental factors. In the field of marine engineering, bolt sleeves are widely used for connection and fixation of various metal structures, which are easily corroded in high-salinity and highly corrosive seawater environments.

[0003] Although advanced non-ferrous materials have excellent properties, they face severe corrosion problems in complex use environments. For example, in marine engineering, seawater erosion can reduce the mechanical properties of bolt sleeves, leading to loose connections and seriously affecting the safety and reliability of the entire engineering facility. To enhance the corrosion resistance of bolt sleeves made of advanced non-ferrous materials, plasma spraying technology has become an important surface treatment method. The present application is a plasma spraying device based on corrosion-resistant surface treatment of a bolt sleeve.

[0004] Existing plasma spraying devices cannot accurately adjust the position of the spraying assembly in a short time, cannot quickly cover different position areas, greatly reducing the spraying efficiency, and cannot meet the efficiency requirements of large-scale production. In addition, the composition of the coating is difficult to stabilize and control, and the composition of the coating sprayed in different batches differs greatly, which seriously affects the improvement effect of the coating on the corrosion resistance of the bolt sleeve.

[0067] In example three, on the basis of examples one and two,

[0068] The two groups of fixed frames 35 are fixed on the supporting plate 34, and the hinged frames 351 are hinged on the fixed frames 35. The top plates 352 are installed on the hinged frames 351 through bolts. The round rods 3521 are locked on the top plates 352. The handles 3522 are fixed on the round rods 3521. The square sleeves 353 are hinged on the fixed frames 35. The inner rods 3531 are movably arranged in the square sleeves 353.

The fifth electric motor 3542 installed on the hinged frame 351 outputs power. After the speed changer 354 changes the rotating speed and torque, the power is transmitted to the rotating shaft 358 through the second connecting belt 3541 to drive the disc 36 installed on the upper end of the rotating shaft 358 to rotate. When the adjusting ring 362 is rotated, the helical groove drives the three groups of clamping blocks 361 to move inward or outward along the sliding grooves of the disc 36 synchronously. This design can quickly and stably clamp workpieces of different sizes.

[0069] The working principle of the present embodiment is that: rotating the adjusting ring 362, the spiral groove drives the three sets of clamping blocks 361 to move inward along the sliding groove of the disc 36 synchronously, and after the clamping of the bolt sleeve is completed, the No. 4 motor 321 on the motor seat 32 starts, the driving wheel of the output shaft of the motor drives the conveyor belt 312 to run, and then drives the supporting plate 34 and the workpiece to move to the spraying area. In the conveying process, the tensioning wheel 313 and the tension spring 314 automatically adjust the tensioning degree of the conveyor belt 312 to ensure stable conveying. The No. 3 hydraulic rod 335 pushes the supporting plate 332, and through the connecting plate 333 and the pin shaft, it drives the baffle 334 to block the supporting plate 34, realizes the positioning of the supporting plate 34, and the workpiece reaches the specified position with the supporting plate 34. After that, the operator rotates the handle 3522 to drive the round rod 3521 to rotate. The round rod 3521 drives the inner rod 3531 to extend or retract in the square sleeve 353 through the connecting plate 3533, and after adjusting to the appropriate position, the inner rod 3531 is inserted into the plug rod 3532 to fix the inner rod 3531, so as to lock the angle of the top plate 352 of the hinged frame 351. According to the shape and height of the workpiece, the stable fixing of workpieces of different shapes is realized. In addition, the hinged frame 351 can rotate to further adjust the angle of the top plate 352, so as to ensure that the surface to be sprayed of the workpiece accurately faces the spraying assembly. While the workpiece is fixed and the angle is adjusted, the liquid supply pump 151 delivers the paint in the paint bucket 14 to the powder conveying pipeline 2531, and the inert gas supply member 16 provides inert gas for the gas conveying pipeline 2532. The two are fully mixed in the mixer 2535, and the flow control valve 2534 accurately controls the flow of powder and gas to ensure uniform and stable mixing. The mixed material is delivered to the nozzle 2541 through the hose, at the same time, the cooling pipeline 2533 is connected with the cooling liquid supply equipment, and the cooling liquid flows in the circulating pipeline in the fixed seat 254 to continuously cool the nozzle 2541, preventing it from being damaged by overheating. The No. 5 motor 3542 is operated, and its power is transmitted to the rotating shaft 358 through the gearbox 354 to change the speed and torque, and then drives the disc 36 to rotate, and then makes the workpiece fixed on the disc 36 rotate at a constant speed. The No. 1 motor 241 drives the threaded rod 242 to move the movable seat 243 along the threaded rod 242, and the transmission beam rod 232 drives the sliding seat 24 to move to realize the accurate position adjustment of the spraying assembly in the horizontal direction. The No. 2 motor 2431 drives the rotating column 244 to rotate, so that the connecting rod 25 and the spraying assembly rotate to spray the workpiece at different angles. The piston rod of the No. 1 hydraulic rod 2511 extends or retracts to push the sliding plate 252, and then drives the U-shaped frame 253, the mixer 2535 and the nozzle 2541 installed on the sliding plate 252 to adjust the position, so as to flexibly change the distance and angle between the nozzle and the workpiece to ensure the accuracy of spraying. The No. 3 motor 2322 drives the transmission rod 2321 to ensure that the two sets of transmission beam rods 232 operate synchronously to ensure that the sliding seat 24 moves smoothly. Finally, the spraying assembly uniformly sprays the mixed material on the surface of the rotating workpiece to form a high-quality corrosion-resistant coating.The waste gas generated in the spraying process is connected through the waste gas treatment component 21 at the rear side of the top box 2 and the bottom box 1, and the waste gas treatment component 21 collects and treats the waste gas.
