Description

Technical Field

[0001] This utility model relates to the technical field of automatic spraying, and more specifically, to an automatic reciprocating spraying device. Background Technology

[0002] In the thermal engineering industry, flue gas emissions contain a large number of particles. When a flue gas analyzer detects the flue gas, these particles can scour the analyzer's probe. Therefore, it is necessary to add a wear-resistant coating to the outer tube of the analyzer probe used to measure flue gas concentration. The wear-resistant coating process requires preheating and spraying the original bare tube, as well as melting the wear-resistant metal powder. A manual acetylene torch mixed with the wear-resistant metal powder is used to weld the powder onto the surface of the analyzer probe's outer tube. Due to the long length of the tube and the need for manual movement, production efficiency is low, resulting in high labor costs. Furthermore, the prolonged high-temperature environment makes workers more prone to fatigue. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides an automatic reciprocating spraying device that can solve the above problems.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: An automatic reciprocating spraying device includes a machine body. A machine tool guide rail is provided at the upper end of the machine body. A spray gun mounting frame is slidably connected to the machine tool guide rail. The spray gun mounting frame includes a U-shaped frame. The top ends of the left and right side plates of the frame are respectively connected to an L-shaped support plate one and an L-shaped support plate two. The upper end of the support plate one is connected to a welding torch through the spray gun mounting plate. The front end of the support plate one is connected to a cutting torch assembly through a cutting torch assembly mounting plate. The output end of the cutting torch assembly is connected to the input end of the welding torch. A variable frequency motor is provided on the upper right side of the machine body. The variable frequency motor is connected to the frame through a transmission assembly. An electric rotary chuck assembly is provided above the machine tool guide rail.

[0005] Furthermore, a bar magnet is connected to each of the left and right sides of the support plate, and a magnetic proximity switch is provided on each of the left and right sides of the machine tool guide rail, opposite to the bar magnet. The magnetic proximity switch is connected to the machine tool guide rail via a movable bracket, and the movable bracket includes a slider that is slidably connected to the machine tool guide rail, and the slider is provided with a locking screw.

[0006] Furthermore, the support plate is provided with several rows of waist-shaped holes for connecting the spray gun mounting plate, and a platform extension frame is connected to the side end of the support plate. The platform extension frame is provided with several connection holes for connecting the spray gun mounting plate.

[0007] Furthermore, the spray gun mounting plate has an L-shaped structure, and a weight reduction hole is provided on the side plate of the spray gun mounting plate. The front end of the side plate has a mounting hole one and a mounting hole two. Both mounting holes one and two are L-shaped. The end of mounting hole two is connected to an arc-shaped mounting hole three. The spray gun mounting plate is connected to the welding torch through mounting holes one and three.

[0008] Furthermore, both the first support plate and the second support plate are provided with rollers at their lower ends, and the rollers are rotatably connected to the upper end of the machine tool guide rail.

[0012] The beneficial effects of this utility model are as follows: This application provides power to the transmission component through a variable frequency motor, thereby driving the welding torch to move back and forth with the spray gun mounting frame to achieve spraying. By achieving back and forth spraying mechanically, on the one hand, the workload can be reduced and labor costs can be lowered.
