Description

An AC arc spraying equipment

technical field

Background technique

With the development of spraying technology, the pursuit of high efficiency and personalization is the frontier development direction. In the field of practical engineering applications, arc spraying has been widely used in surface treatment processes such as spraying and anticorrosion. This kind of method can make the metal as a kind of spray paint uniformly and densely cover the surface of the workpiece more conveniently and efficiently, so as to achieve anti-corrosion, wear-resistant and other effects, while the traditional spraying process is mainly used for spraying operations of various non-metallic materials. The method is completely different from the traditional spraying process in the past, and has broad application prospects.

However, when the existing AC arc spraying equipment is in use, the workpiece to be sprayed cannot be effectively fixed. When the workpiece is sprayed, the workpiece is prone to shaking, which leads to uneven spraying, low stability, and residues. The rate of defective products and rework is significant, and after the workpiece is sprayed, it is necessary to move the workpiece to the drying equipment to dry it in time. Moving the workpiece back and forth in this way greatly reduces the work efficiency of the workpiece spraying process, and it is easy to cause the surface to be sprayed with paint. The surface is damaged and the practicability is low, especially for cylindrical hollow pipe fittings. When the workpiece is sprayed, because its outer surface is an outer circular surface, it is difficult to achieve a better fixing effect with the existing fixing methods. It is easy for the fixed structure to block the outer surface of the pipe fittings, resulting in a blind area of spraying and affecting the processing efficiency of the pipe fittings.

As an embodiment of the present invention, as shown in FIG. 3 and FIG. 4 , the drive mechanism 2 includes a motor 21, a gear one 22, a gear two 23, a belt 24, a pulley 25, a gear three 26, and the rotating shaft 51 Gear 3 26 and pulley 25 are fixedly socketed on the outer surface from left to right in sequence, and the output end of the motor 21 is fixedly connected with gear 1 22, and the gear 3 26 and gear 1 22 are meshed and connected by gear 2 23 , the second gear 23 is rotatably connected to the rotating groove on the upper outer surface of the fixed platform 18 through the rotating shaft 51 , and the belt pulley 25 is connected to the transmission pulley 15 through a belt 24 .

When working, the motor 21 conducts conduction, and then drives the gear one 22 to rotate through the output shaft, and then further drives the gear three 26 to rotate through the gear two 23, so that the rotating shaft 51 rotates, and drives the fixing mechanism 5 to carry the pipe to rotate. The pulley 25 cooperates with the belt 24 to drive the transmission wheel 15 to rotate, and then realizes the rotation of the threaded rod 13, and controls the fixed seat 17 and the nozzle 14 that are threadedly connected with the threaded rod 13 to move left and right to spray the lower pipes, and the same rotation of the threaded rod 13 It will also drive the operation of the exhaust mechanisms 3 at both ends.

As an embodiment of the present invention, as shown in Figure 3 and Figure 6, the exhaust mechanism 3 includes a purification box 31, an exhaust nozzle 32, fan blades 33, and a rotating groove 34, and the inner wall of the box body 1 A rotating groove 34 is provided, and a purification box 31 is fixedly connected to the corresponding position of the outer surface of the rotating groove 34.

An exhaust nozzle 32 is fixed on the outer surface of the purification box 31 .

When working, the fan blade 33 rotates inside the rotating groove 34 during the rotation of the threaded rod 13, and then the air inside the box body 1 is sucked and transported to the inside of the purification box 31 to complete the purification and then discharged to the outside through the exhaust pipe port 32. During the process, because the threaded rod 13 rotates forward and backward, the designs of the fan blades 33 on both sides of the threaded rod 13 are different. To the inside of the box body 1, the air flow inside the box body 1 is increased, and the right end is pumped and discharged to the right side purification box 31 for filtration and purification. Similarly, the threaded rod 13 rotates counterclockwise, and the gas suction process of the exhaust mechanism 3 on both sides is opposite. The drive mechanism 2 and the exhaust mechanism 3 are designed so that the exhaust assembly is also driven to run during the operation based on the fixed mechanism 5, and the air inside the box body 1 is sucked to the purification box 31 to be purified and then discharged through the exhaust nozzle 32. Reduce the impact of toxic and harmful gases on the working environment, and ensure a safe and pollution-free working environment.

Working principle: The user connects the two ends of the cylindrical hollow pipe to the surface of the elastic strip 57 in the fixing mechanism 5 on both sides, and then the air pump 4 runs, and the air is delivered to the rotary joint 42 through the hose 41, and the air inside the rotating shaft 51 The channel 55 enters the airbag 58, and the airbag 58 expands, and then squeezes and expands the elastic strip 57 outward, so that the elastic strip 57 is uniformly deformed and expanded outwards, and the airbag 58 reaches the inner wall of the fixed hollow pipe to realize the fixing of the pipe, and then the air pump 4 is closed, and the solenoid valve 561 is closed. At this time, the motor 21 conducts conduction, and then drives the gear one 22 to rotate through the output shaft, and then further drives the gear three 26 to rotate through the gear two 23, so that the rotating shaft 51 rotates, and then the turntable 54 is in the position of the bearing 53. Under the action, it rotates inside the fixed ring 52.

The displacement sprays the lower pipe fittings, and the upper nozzle 14 evenly sprays the pipe fittings surface. During the rotation of the threaded rod 13, the fan blade 33 rotates inside the rotating groove 34, and then sucks and transports the air inside the box 1 to the purification box 31. After the internal purification is completed, the outside is discharged through the exhaust pipe port 32. During this process, because the threaded rod 13 rotates forward and backward, the designs of the fan blades 33 on both sides of the threaded rod 13 are different, that is, when the threaded rod 13 rotates clockwise, the fan blade at the left end 33 rotates to extract air from the left exhaust pipe port 32, transport it to the inside of the box body 1, increase the air flow inside the box body 1, and the right end is pumped and discharged to the right side purification box 31 to filter and purify. Similarly, the threaded rod 13 counterclockwise Rotate, and the gas suction process of the exhaust mechanism 3 on both sides is opposite. By designing the driving mechanism 2 and the exhaust mechanism 3, the exhaust assembly is also driven to operate during the operation based on the fixed mechanism 5, and the air inside the box 1 is sucked. After the purification box 31 is purified, it is discharged through the exhaust pipe port 32, reducing the impact of toxic and harmful gases on the working environment, ensuring that the working environment is safe and pollution-free. The air passage 55 inside the rotating shaft 51 enters the channel 562 and then enters the fixed piece 566 through the air pipe 563, and is sprayed out from the air injection hole 564 through the through hole in the fixed piece 566. During this process, the electric heating wire 565 distributed in a spiral conducts electricity. The heated gas passes through multiple sets of annularly distributed drying components 56 in the double-sided fixing mechanism 5 to realize the drying and use of the surface of the sprayed pipe fittings, which saves the operation steps of the secondary moving and drying operation of the pipe fittings, and reduces the effect of pollutants on the pipe fittings. probability, improve product quality, the design purpose of solenoid valve 561 is to control the opening and closing of air bag 58 gas injection process.
