Description

Technical Field

[0001] The present invention relates to the technical field of material surface treatment, and particularly to a plasma spraying device for corrosion-resistant surface treatment of bolt sleeves. Background Art

[0002] In the current rapid development of technology, advanced non-ferrous metal materials, due to their excellent properties such as high strength, low density, good electrical and thermal conductivity, are widely used in many key fields. In the aerospace field, aircraft engine components and fuselage structural parts are mostly made of advanced non-ferrous metal materials such as titanium alloys. Among them, bolt sleeves, as key components for connection and fastening, are crucial for ensuring the stability of the overall aircraft structure, and their quality directly affects flight safety. In the field of electronic information, heat sinks, circuit boards and other electronic components made of copper alloys and aluminum alloys are efficiently assembled and fixed with the help of bolt sleeves to ensure the stable operation of electronic devices. 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 metal materials. Under complex mechanical stresses and environmental factors, they need to maintain reliable connection performance. In the field of ocean engineering, bolt sleeves are widely used for the connection and fixation of various metal structures. These bolt sleeves are constantly in a high-salinity and highly corrosive environment of seawater and are extremely vulnerable to corrosion.

[0003] Although advanced non-ferrous metal materials have excellent properties, they face severe corrosion problems in complex usage environments. Taking ocean engineering as an example, the erosion of seawater will reduce the mechanical properties of bolt sleeves, resulting in loose connections, seriously affecting the safety and reliability of the entire engineering facilities. To enhance the corrosion resistance of bolt sleeves made of advanced non-ferrous metal materials, plasma spraying technology has become an important surface treatment method. The present invention is a plasma spraying device for corrosion-resistant surface treatment of bolt sleeves.

[0004] Existing plasma spraying devices are difficult to accurately adjust the position of the spraying components in a short time and cannot quickly cover different position areas, greatly reducing the spraying efficiency and unable to meet the requirements of large-scale production for efficiency. Moreover, the coating composition is difficult to stably control, and there are significant differences in the coating composition sprayed in different batches, seriously affecting the improvement effect of the coating on the corrosion resistance of bolt sleeves.

[0029] Embodiment 3, based on Embodiments 1 and 2, Two sets of fixing brackets 35 are fixed on the pallet 34. An articulated bracket 351 is articulated on the fixing bracket 35. A top plate 352 is installed on the articulated bracket 351 by bolts. A round rod 3521 is locked on the top plate 352. A handle 3522 is fixed on the round rod 3521. A square sleeve 353 is articulated on the fixing bracket 35. An inner rod 3531 is movably arranged inside the square sleeve 353. A linkage plate 3533 is installed on the inner rod 3531 by a pin shaft. The linkage plate 3533 is fixedly connected to the round rod 3521. A jack is arranged on the inner rod 3531.

A spiral groove is arranged on the adjusting ring 362. The lower ends of the three clamping blocks 361 are in threaded cooperation with the spiral groove on the adjusting ring 362. Its functions are as follows: Rotate the handle 3522 to drive the round rod 3521 to rotate. The round rod 3521 drives the linkage plate 3533, prompting the inner rod 3531 to expand and contract in the square sleeve 353. When the inner rod 3531 reaches the appropriate position, insert the plug rod 3532 into the jack of the inner rod 3531 and fix it with the square sleeve 353 to lock the angle of the top plate 352. The rotatable characteristic of the articulated bracket 351 endows the top plate 352 with the ability to flexibly adjust the angle within a certain range, enabling the device to adapt to various complex-shaped workpieces such as bolt sleeves, ensuring that the surface to be sprayed of the workpiece is accurately oriented towards the spraying component, significantly improving the spraying accuracy and coverage, and fully meeting the diverse spraying process requirements. The fifth motor 3542 installed on the articulated bracket 351 outputs power. After the speed and torque are changed by the gearbox 354, it is transmitted to the rotating shaft 358 through the second connecting belt 3541, driving the disc 36 installed at the upper end of the rotating shaft 358 to rotate. When rotating the adjusting ring 362, the spiral groove drives the three clamping blocks 361 to move synchronously inwards or outwards along the chute of the disc 36. This design can quickly and stably clamp workpieces of different sizes.

[0030] Working principle of this embodiment: Rotate the adjusting ring 362 to drive the three clamping blocks 361 to move inward synchronously along the sliding grooves of the disc 36 through the spiral grooves, and complete the clamping of the bolt sleeve. The fourth motor 321 on the motor base 32 is started, and the driving wheel on its output shaft drives the conveyor belt 312 to operate, thereby driving the support plate 34 and the workpiece to move towards the spraying area. During the conveying process, the tension pulley 313 and the tension spring 314 automatically adjust the tension of the conveyor belt 312 to ensure stable conveying. Push the support plate 332 through the third hydraulic rod 335, drive the baffle 334 through the connecting plate 333 and the pin shaft, and the baffle 334 can block the support plate 34 to achieve the positioning of the support plate 34. After the workpiece reaches the designated position with the support plate 34, the operator rotates the handle 3522 to drive the round rod 3521 to rotate. The round rod 3521 makes the inner rod 3531 stretch and contract in the square sleeve 353 through the linkage plate 3533. After adjusting to the appropriate position, insert the insertion rod 3532 to fix the inner rod 3531, thereby locking the angle of the top plate 352 on the articulated frame 351, and realizing the stable fixation of workpieces with different shapes according to the shape and height of the workpiece. In addition, the articulated frame 351 can rotate to further adjust the angle of the top plate 352 to ensure that the surface of the workpiece to be sprayed accurately faces the spraying assembly. While the workpiece is fixed and the angle is adjusted, the liquid supply pump 151 transports the paint in the paint bucket 14 to the powder feeding pipeline 2531, and the inert gas supply part 16 provides inert gas for the gas supply pipeline 2532. The two are fully mixed in the mixer 2535, and the flow control valve 2534 precisely regulates the powder feeding and gas supply flow rates to ensure uniform and stable mixing. The mixed material is transported to the nozzle 2541 through the hose. At the same time, the cooling pipeline 2533 is externally connected to the coolant supply equipment, and the coolant circulates in the pipeline in the fixed seat 254 to continuously cool the nozzle 2541 to prevent it from being damaged due to overheating. Operate the fifth motor 3542, and its power changes the speed and torque through the gearbox 354, and is transmitted to the rotating shaft 358 through the second connecting belt 3541 to drive the disc 36 to rotate, thereby making the workpiece fixed on the disc 36 rotate at a constant speed. Drive the threaded rod 242 through the first motor 241 to make the movable seat 243 move along the threaded rod 242, and combine the transmission beam rod 232 and the conveyor belt to drive the sliding seat 24 to move, realizing the precise position adjustment of the spraying assembly in the horizontal direction.
