Description

Technical Field

[0001] This utility model relates to the technical field of bearing processing, and in particular to a device for spraying anti-rust paint on the inner surface of bearing rings. Background Technology

[0002] Bearings are essential components in modern machinery. Their main function is to support rotating mechanical parts, reduce friction during movement, and ensure rotational accuracy. The bearing ring generally refers to the outer ring, whose inner surface requires a rust-preventive coating or lubricant to ensure proper installation and processing. Existing technology publication CN214347409U proposes a bearing outer ring inner surface spraying device, including a support plate, mounting plate, fastener mechanism, painting mechanism, protective box, conveyor belt, and guide plate. The mounting plate's adjacent ends are fixedly connected to the front and rear sides of the support plate, respectively. The bottom end of the fastener mechanism is fixedly connected to the top surface of the left end of the support plate. The bottom end of the painting mechanism is fixedly connected to the middle of the top surface of the rear end of the mounting plate. The bottom of the protective box is fixedly connected to the front right side of the top surface of the support plate. However, after each spraying, manual removal is required, resulting in low processing efficiency. Furthermore, the slow drying speed after spraying also affects processing efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bearing ring inner surface anti-rust paint spraying device to improve the continuity of work and increase work efficiency.

[0004] This utility model discloses a bearing ring inner surface anti-rust paint spraying device, comprising a worktable, multiple three-dimensional components, a base frame, a vertical plate, a top plate, a spraying component, a conveying component, and a drying component. Three-dimensional components are fixedly installed at the four corners of the worktable, with their bottoms fixedly installed on the top of the base frame. A vertical plate is fixedly installed in the middle of the rear side wall of the worktable, and a top plate is fixedly connected to the top of the vertical plate. The spraying component is installed on the rear side wall of the vertical plate, with its output end installed at the bottom of the top plate. The conveying component is installed on the top left end of the worktable, and the drying component is installed on the top right end of the worktable. The bearing ring is placed on the left end of the worktable and conveyed by the conveying component. After the bearing ring moves to the spraying position, the inner surface of the bearing ring is sprayed by the spraying component. After spraying, the next bearing ring moves to the right, entering the drying component for drying, which improves work efficiency.

[0005] Preferably, the spraying assembly includes a storage tank, a pump, a pumping pipe, a delivery hose, a vertical pipe, an electric telescopic rod, a spraying disc, and a spray nozzle. The storage tank is installed on the rear side wall of the vertical plate, and a filling pipe is provided at the top of the storage tank. The pump is installed at the top rear end of the top plate, and the input end of the pump is connected to the pumping pipe. The input end of the pump passes through the top of the storage tank and extends to the bottom of the storage tank. The output end of the pump is connected to the delivery hose, and the output end of the delivery hose is connected to the input end of the vertical pipe. The vertical pipe is slidably installed at the front end of the top plate, and the bottom of the vertical pipe... The unit is connected to a spraying disc, with a nozzle installed at the bottom of the disc. The nozzle has multiple spray holes. An electric telescopic rod is installed at the bottom of the top plate, and its telescopic end is connected to the top of the spraying disc. Paint is added to the storage tank through the filling pipe. The pump is started to extract the paint through the extraction pipe. After the bearing ring moves to the spraying position, the electric telescopic rod is started to push the spraying disc downward, causing the vertical pipe to slide on the top plate and drive the nozzle into the bearing ring. The paint enters the nozzle through the infusion hose and the vertical pipe and is sprayed onto the inner surface of the bearing ring.

[0006] Preferably, the system also includes a drive motor, a stirring shaft, multiple stirring rods, two second electric telescopic rods, and two V-shaped clamps. The drive motor is installed at the bottom of the storage tank, and the output end of the drive motor passes through the bottom of the storage tank and is fitted with a stirring shaft. Multiple stirring rods are evenly installed on the outer wall of the stirring shaft. The two second electric telescopic rods are symmetrically installed at the front and rear ends of the top of the worktable, and V-shaped clamps are installed at the telescopic ends of the second electric telescopic rods. After the bearing ring moves to the spraying position in the middle of the worktable, the second electric telescopic rods are activated to push the V-shaped clamps to move, so that the two V-shaped clamps clamp the bearing ring to ensure stability during spraying. The drive motor is activated to drive the stirring shaft and stirring rods to rotate, agitating the paint inside the storage tank, preventing paint sedimentation, and improving the spraying quality.

[0007] Preferably, the conveying assembly includes two moving beams, multiple conveying wheels, multiple drive pulleys, multiple drive belts, two motor frames, two conveying motors, multiple guide wheels, conveying belts, and adjusting components. Adjusting slots are provided on the front and rear sides of the top left end of the worktable. The two moving beams are located in the two adjusting slots respectively. Multiple conveying wheels are evenly spaced and rotatably mounted on the top of the moving beams. Drive pulleys are installed at the input ends of the bottom of the conveying wheels, and adjacent drive pulleys are connected by drive belts. Two motor frames are installed at the bottom left end of the moving beams, and the conveying motors are installed inside the motor frames. The output end of the conveying motors is connected to the input end of the left-end drive pulleys. Multiple guide wheels are alternately rotatably mounted on the top of the moving beams and the conveying wheels. Two conveying belts are respectively installed on the front and rear sets of conveying wheels and guide wheels. The bearing ring is placed on the left end of the worktable. The conveying motors are started to drive the drive pulleys to rotate. Through the cooperation of multiple drive belts, multiple conveying wheels are driven to rotate, causing the conveying belts to rotate. The two conveying belts drive the bearing ring to move on the top of the worktable, conveying the bearing ring and improving work efficiency.

[0008] Preferably, the adjusting component includes two sets of limiting sliders, two fixed plates, a rotating rod, an adjusting motor, and two adjusting pull plates. Limiting grooves are formed at both ends of the adjusting groove.

The two fixed plates are fixedly installed at the front and rear ends of the left side of the worktable. The rotating rod is rotatably installed between the two fixed plates. Threaded grooves are symmetrically formed on the outer wall of the rotating rod. The input end of the rotating rod is connected to the output end of the adjusting motor. The two adjusting pull plates are symmetrically screwed onto the outer wall of the rotating rod, and each adjusting pull plate is connected to one of the two motor frames. Starting the adjusting motor drives the rotating rod to rotate, which in turn moves the two adjusting pull plates, thus pushing the moving beam within the adjusting groove to adjust the distance between the two conveyor belts. When the moving beam moves, it causes the limiting sliders to move within the limiting grooves, ensuring stability during movement.

[0009] Preferably, the drying assembly includes a drying hood, multiple drying lamps, multiple reflective partitions, two conveyor rollers, a second conveyor motor, and a conveyor belt. The drying hood is installed on the top right end of the workbench. Multiple drying lamps are installed inside the top of the drying hood. Multiple reflective partitions are alternately installed inside the drying hood along with the drying lamps. A conveyor trough is provided on the top right end of the workbench. Two conveyor rollers are rotatably installed at the left and right ends of the conveyor trough. The input end of the left conveyor roller is connected to the output end of the second conveyor motor. A conveyor belt is installed between the two conveyor rollers. The drying lamps are activated to preheat the inside of the drying hood. After the coating is completed, the last bearing ring moves to the right, pushing the coated bearing ring to the surface of the conveyor belt. At the same time, the second conveyor motor is activated to drive the conveyor rollers to rotate, so that the conveyor belt carries the bearing ring into the drying hood, thereby increasing the drying speed of the coating and improving work efficiency. The reflective partitions enable more uniform heat distribution and ensure drying quality.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the bearing ring is placed on the left end of the worktable and can be conveyed by the conveying component. After the bearing ring moves to the spraying position, the inner surface of the bearing ring is sprayed by the spraying component. After the spraying is completed, the next bearing ring moves to the right and enters the drying component to dry the bearing ring, which helps to improve work efficiency. Attached Figure Description
