Description

Technical Field

[0001] This utility model relates to the field of machine tool manufacturing technology, specifically to an inner spraying device for machine tool manufacturing. Background Technology

[0002] When metals come into contact with the medium in their surrounding environment, they are damaged by chemical and electrochemical processes; this is called metal corrosion. In particular, metals readily form rust in the presence of water; this specific form of corrosion is called rusting. It is worth noting that, with the exception of a few metals such as gold, platinum, and titanium, most metals tend to transform into an ionic state, meaning that metal corrosion is a spontaneous and ubiquitous phenomenon.

[0003] Once metals are corroded or rusted, their appearance, color, and mechanical properties change significantly. Rust on the outer surface of parts not only affects the quality of paint, but rust on the inner surface can also cause rust particles to flake off, thus shortening the service life of moving parts. Therefore, rust is not allowed on either the outer or inner surface of parts.

[0004] The technical requirements for rust prevention treatment of the inner wall of the gearbox are particularly stringent. Rust prevention measures must be implemented while ensuring that key technical parameters such as part dimensions, surface condition, and internal cavity cleanliness are not affected. In particular, large parts such as gearboxes, which are usually produced using casting processes, are more susceptible to corrosion due to their rough surfaces and numerous micropores. Once rust occurs, it is more complex and difficult to treat. Therefore, this case study was developed to address these issues in depth. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an inner spraying device for machine tool production, comprising: a concave transport table, a chain plate conveyor, a spraying bracket, and a spraying limiting structure, wherein the chain plate conveyor is installed on the inner side of the concave transport table, the spraying bracket is installed on the concave transport table, and the spraying limiting structure is installed on the spraying bracket;

[0006] The spraying limiting structure includes: a pair of spraying hydraulic push rods, a lifting spraying plate, a rotating helical gear, a rotating sleeve ring helical gear, a rotating disk, a rotating drive motor, a flexible diversion tube, a Y-type diverter tube, a pair of L-type spraying tubes, a concave bearing block, an angle drive motor, an angle gearbox, a T-type spraying tube, a spraying pump, a spraying box, a spraying nozzle, an angle adjustment assembly, and a limiting assembly;

[0007] A pair of spraying hydraulic push rods are mounted parallel to each other on the spraying bracket. The lifting spraying plate is mounted on the pushing end of the pair of spraying hydraulic push rods. The rotating disk is inserted into the lifting spraying plate via bearings. The rotating drive motor is mounted on the lifting spraying plate. The rotating helical gear is mounted on the rotating disk and on the drive end of the rotating drive motor, with the rotating helical gear meshing with the rotating helical gear. The Y-shaped diverter is inserted into the rotating disk. The spraying box is mounted on the spraying bracket, and the spraying pump is mounted on the spraying box. The flexible drainage tube is connected to the spraying pump, and the flexible drainage tube is inserted into the inner side of the Y-shaped diverter tube through a bearing. The concave bearing block is installed on the rotating disk. The T-shaped spraying tube is inserted into the concave bearing block. A pair of L-shaped spraying tubes are inserted into the Y-shaped diverter tube, and the pair of L-shaped spraying tubes are connected to the T-shaped spraying tube. The angle gearbox is fitted onto the T-shaped spraying tube. The drive end of the angle drive motor is connected to the angle gearbox. The spraying nozzle is installed on the T-shaped spraying tube through an angle adjustment assembly. The limiting assembly is installed on the spraying bracket.

[0008] It should be noted that, as described above, the machine tool box is transported by a chain-plate conveyor on the concave transport platform. Simultaneously, the extension and retraction of a pair of hydraulic push rods on the spraying bracket drives the lifting spraying plate on its push end to move stably up and down. The lifting spraying plate then drives a rotating disk and a rotary drive motor. The rotary drive motor rotates a helical gear on its drive end, which in turn drives a rotating ring helical gear, which in turn drives the rotating disk. This causes the rotating disk to drive a concave bearing block on it to rotate stably horizontally. Meanwhile, the concave... The bearing block drives the T-shaped spray pipe on it to rotate stably horizontally. At the same time, the angle drive motor runs, which drives the angle gearbox on the drive end of the angle drive motor. The angle gearbox drives the T-shaped spray pipe to adjust its angle, thereby changing the angle of the T-shaped spray pipe. Meanwhile, the spray pump guides the material from the inside of the spray box to the inside of the flexible guide pipe. The flexible guide pipe guides the material to the inside of the Y-shaped diverter pipe. The Y-shaped diverter pipe guides the material through a pair of L-shaped spray pipes to the inside of the T-shaped spray pipe. At the same time, the T-shaped spray pipe guides the material to the inside of the angle adjustment component. Meanwhile, the limiting component performs internal spraying on the machine tool box.

[0009] Preferably, the limiting component includes: two pairs of lifting hydraulic push rods, a loop-shaped lifting limiting block, a loop-shaped inflatable airbag, an air pump, and a pressure sensor;

[0010] Two pairs of lifting hydraulic push rods are installed on the inner side of the spraying bracket, the loop-shaped lifting limit block is installed on the pushing end of the two pairs of lifting hydraulic push rods, the loop-shaped inflatable airbag is inserted into the loop-shaped lifting limit block, the air pump is connected to the loop-shaped inflatable airbag, and the pressure sensor is installed on the loop-shaped inflatable airbag.

[0011] It should be noted that, in the above, the extension and retraction of two pairs of lifting hydraulic push rods drives the loop-shaped lifting limit blocks on the pushing ends of the two pairs of lifting hydraulic push rods. The air pump inside the loop-shaped lifting limit blocks inflates the loop-shaped airbags. The expansion of the loop-shaped airbags compresses and expands the machine tool box from the outside, fixing it in place. At the same time, the inflation of the air pump is controlled by a pressure sensor.

[0012] Preferably, the angle adjustment assembly includes: a telescopic spraying disc, a telescopic spraying inner shaft tube, a spider web spraying tube, a limiting ring, a repulsion ring electromagnet, a repulsion ring magnet, a tension sleeve spring, and a sealed telescopic bearing.

[0013] The telescopic spraying inner tube is inserted into the inner side of the T-shaped spraying tube via a sealed telescopic bearing. The telescopic spraying disc is mounted on the telescopic spraying inner tube. The spider web spraying tube is inserted into the telescopic spraying disc and connected to the telescopic spraying inner tube. The limiting ring is fitted onto the telescopic spraying inner tube. The repulsion ring electromagnet is mounted on the limiting ring. The repulsion ring magnet is mounted on the telescopic spraying disc. The tension sleeve spring is fitted onto the telescopic spraying inner tube and the T-shaped spraying tube, and the tension sleeve spring is connected to the telescopic spraying disc and the limiting ring respectively.

[0014] It should be noted that, in the above process, the repulsion ring electromagnet on the limiting ring magnetically repels the repulsion ring magnet. The repulsion ring magnet drives the telescopic spraying inner shaft tube on it, which in turn drives the telescopic spraying disc on it to move up and down stably. Simultaneously, the telescopic spraying disc drives the spider web spraying pipe on it to move up and down stably. At the same time, the spider web spraying pipe sprays several spray nozzles onto the inside of the machine tool box. By allowing for horizontal rotation and vertical angle adjustment, as well as the stable extension and retraction of the inner side of the T-shaped spraying pipe, the inside of the machine tool box is sprayed, thus avoiding the occurrence of spraying dead corners during the spraying process.

[0015] Preferably, the repulsion annular electromagnet is provided with a resistance regulator.

[0016] Preferably, a scanning camera is provided on the telescopic spraying disc.

[0017] Preferably, the spray box is equipped with a pressure sensor. Beneficial effects

It offers the following advantages: This internal spraying device for machine tool production, through a combination of a rotating disc, a rotating helical gear, and a rotating ring helical gear, achieves stable horizontal rotation of the rotating disc, its upper concave bearing block, and the T-shaped spraying pipe, thereby ensuring 360-degree spraying of the inner side of the machine tool housing and effectively avoiding spraying dead angles; the operation of the angle drive motor and angle gearbox further allows for angle adjustment of the T-shaped spraying pipe, making the spraying more precise and comprehensive; the spraying system can not only rotate horizontally but also be adjusted vertically via a lifting spraying plate and a lifting hydraulic push rod, making the spraying operation more flexible and adaptable to machine tool housings of different sizes and shapes; the design of the telescopic spraying inner shaft tube and the telescopic spraying disc allows for stable vertical lifting of the spraying disc, further enhancing the flexibility and coverage of the spraying. The system utilizes a combination of a spiral lifting limit block and a spiral inflatable airbag to compress and expand the outer side of the machine tool housing, ensuring its stability during spraying and preventing displacement or shaking. A pressure sensor controls the inflation of the air pump, ensuring uniform and safe inflation. The coordinated operation of electrical and mechanical components automates and automates the spraying process, reducing manual operation and improving efficiency and quality. The magnetic repulsion design of the repulsion ring electromagnet and repulsion ring magnet provides stable lifting power for the spraying disc, further enhancing system stability and reliability. Components such as the spraying pump, flexible drainage pipe, and Y-shaped diverter pipe ensure efficient transfer and diversion of the spraying material from the spraying box to the T-shaped spraying pipe, guaranteeing continuous and uniform spraying.
