Description

Technical Field

[0001] This invention belongs to the field of material processing technology, and in particular relates to an automated rotary device for processing waterproof and sand-resistant tubular materials. Background Technology

[0002] When using water jet cutting to obtain circumferential parts from tubular materials, the material is first disassembled axially, then laid flat on a cutting table, and finally the parts are obtained using traditional methods. This not only destroys the original shape of the material but is also time-consuming, labor-intensive, and wasteful of materials. Direct cutting on the tubular material is also inefficient due to the curvature of the material, limiting the working area for water jet cutting and requiring the material to be rearranged after each operation. Furthermore, it is impossible to perform circumferentially sized parts. While circumferentially sized parts can be obtained by clamping the material in a chuck and manually rotating the indexing plate after each operation, ensuring accuracy, the chuck is submerged in water, making it highly susceptible to rust and corrosion. Precision components such as bearings are also affected by corrosion and corrosive agents, reducing their lifespan or even causing damage. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automated rotary device for processing waterproof and sand-resistant tubular materials that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: an automated rotary device for processing waterproof and sand-resistant tubular materials, including a chuck clamping servo drive system, an external clutch reduction device installed at one end of the chuck clamping servo drive system, a chuck rotation servo drive system installed at one end of the external clutch reduction device, a table frame automated control system fixedly connected to the lower surface of the chuck clamping servo drive system, the chuck rotation servo drive system and the external clutch reduction device, a water jet cutting liquid level management system fixedly connected to one side of the table frame automated control system, a coaxial waterproof and sand-resistant mechanism installed on one side of the water jet cutting liquid level management system, the coaxial waterproof and sand-resistant mechanism connected to the chuck rotation servo drive system, and a rust-resistant chuck mechanism installed on one side of the coaxial waterproof and sand-resistant mechanism.

[0005] Preferably, the chuck rotation servo drive system includes a servo motor, the output shaft of the servo motor is equipped with a clutch, one end of the clutch is equipped with a reduction mechanism, and one end of the reduction mechanism is equipped with a sprocket.

[0006] Preferably, the coaxial waterproof and sand-blocking mechanism includes airbags, and a plurality of airbags are provided. Each airbag is fixedly connected to one side of the inner wall of the water tank. A first liquid level and a second liquid level are respectively provided at the bottom and top of the inside of the water tank. A drain pipe is provided on one side of the water tank.

[0007] Preferably, the table frame automated control system includes a ball valve and an electric ball valve, with one end of the ball valve fixedly connected to an electric ball valve, and the electric ball valve connected to a coaxial waterproof and sand-blocking mechanism via a connecting pipe.

[0008] Preferably, the coaxial waterproof and sand-blocking mechanism includes a second sprocket, which is sleeved on one end of the inner shaft. The inner shaft is rotatably installed in the inner shaft sealing mechanism, which is located in the mounting base.

[0009] Preferably, the mounting base is disposed on one side of the middle upright plate, the middle upright plate is disposed on one side of the water tank, a pulley is also sleeved on one end of the inner shaft, an inner shaft flushing pipe is connected to one end of the inner shaft, and an outer shaft is disposed on the outside of the inner shaft.

[0010] Preferably, an outer shaft flushing pipe is provided above the middle upright plate, an outer shaft sealing mechanism is installed at one end of the outer shaft, and a tubular material is connected to one side of the outer shaft sealing mechanism.

[0011] This invention relocates the torque amplification mechanism, originally located inside the chuck, to the outside of the chuck. Since the entire chuck and material are submerged in water, and the reduction mechanism is a precision transmission mechanism, if it were located inside the chuck, it would be susceptible to corrosion from water and the effects of corrosive abrasive, causing jamming, transmission failure, and even structural damage. Moving the reduction mechanism outside the chuck eliminates these problems. The power amplified by the reducer is then transmitted to the coaxial waterproof and sand-blocking mechanism via sprockets and chains.

[0012] The internal flushing system of this invention is divided into two lines, connected to the internal shaft flushing pipeline and the external shaft flushing pipeline respectively. The main body of the waterjet cutting liquid level management system is a water tank, inside which an air bladder is installed. Compressed air enters and exits the air bladder through the air bladder inlet / outlet pipeline. When the liquid level in the water tank reaches the first liquid level, the air bladder inflates; when it reaches the second liquid level, waterjet cutting operations can begin. When changing materials, the air bladder deflates; after changing materials, the air bladder inflates again, thus controlling the liquid level in the water tank and facilitating the loading and unloading of materials manually or by an external robotic arm.

[0013] This invention addresses the issue of waterproofing and sand-blocking measures required for the other ends of the inner and outer shafts and the anti-rust chuck mechanism, located on the right side of the intermediate vertical plate, within the water tank of the waterjet cutting fluid level management system. To prevent water from flowing to the left side of the intermediate vertical plate and allowing diamond abrasive to enter the coaxial waterproof and sand-blocking mechanism, damaging bearings and other precision components, sealing mechanisms are designed at both the outer and inner shaft sealing mechanisms. Waterproofing utilizes plug seals and O-rings, while preventing diamond abrasive damage to the plug seals and bearings is achieved through multiple blocking rings. The other ends are connected to an internal cavity flushing system, effectively flushing away diamond abrasive accumulated outside the blocking rings of the inner and outer shaft sealing mechanisms. The outer shaft flushing pipe, through the internal water channel of the intermediate vertical plate, directly discharges the accumulated diamond abrasive into the water tank; the inner shaft flushing pipe, through the internal water channel of the inner shaft, discharges the accumulated diamond abrasive into the chuck. The original reduction gear mechanism inside the chuck has been discarded. The diamond abrasive is discharged into the water tank through multiple abrasion holes on the chuck, without affecting the normal operation of the jaw mechanism within the rust-resistant chuck. All parts of the rust-resistant chuck mechanism are made of stainless steel and will not rust. Attached Figure Description

Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1 to 4 As shown in the figure, an automated rotary equipment for processing waterproof and sand-resistant tubular materials provided in this embodiment of the invention includes a chuck clamping servo drive system 1. An external clutch reduction device 3 is installed at one end of the chuck clamping servo drive system 1, and a chuck rotation servo drive system 2 is installed at the other end of the external clutch reduction device 3. A table-mounted automated control system 8 is fixedly connected to the lower surfaces of the chuck clamping servo drive system 1, the chuck rotation servo drive system 2, and the external clutch reduction device 3. A water jet cutting liquid level management system 6 is fixedly connected to one side of the table-mounted automated control system 8. A coaxial waterproof and sand-resistant mechanism 4 is installed on one side of the water jet cutting liquid level management system 6. The coaxial waterproof and sand-resistant mechanism 4 is connected to the chuck rotation servo drive system 2, and a rust-resistant chuck mechanism 5 is installed on one side of the coaxial waterproof and sand-resistant mechanism 4. First, water is added to the water tank of the water jet cutting liquid level management system 6, and simultaneously, the internal cavity flushing system operates. After the water level in the tank reaches the first designated position, the material is manually or by an external robotic arm moved to the chuck jaws and positioned. Then, the automated control system controls the chuck clamping servo drive system to clamp the material. The servo motor automatically stops after detecting that the specified torque has been reached, and simultaneously, the external clutch reduction mechanism disengages. The chuck rotation servo drive system 2 then operates, controlling the chuck to rotate the material to the specified zero position. Once this is complete, the servo motor stops. Finally, the airbag 401 of the waterjet cutting liquid level management system 6 inflates, stopping after a certain delay. Water addition stops once the liquid level in the tank reaches the second specified position.

[0019] The chuck rotation servo drive system 2 includes a servo motor 201. A clutch 202 is mounted on the output shaft of the servo motor 201. A reduction mechanism 203 is mounted on one end of the clutch 202, and a sprocket 204 is mounted on the other end of the reduction mechanism 203. This transfers the reduction mechanism, which originally amplified torque inside the chuck, to the outside of the chuck. Because the entire chuck and the material are submerged in water, and the reduction mechanism 203 is a precision transmission mechanism, if it were located inside the chuck, it would be subject to water corrosion and the influence of corrosive abrasive, causing jamming, transmission failure, and even structural damage. Moving the reduction mechanism outside the chuck avoids these effects. Finally, the power amplified by the reducer is transmitted to the coaxial waterproof and sand-blocking mechanism via the sprocket and chain.

[0020] The coaxial waterproof and sand-blocking mechanism 4 includes several airbags 401, each fixedly connected to one side of the inner wall of the water tank 405. A first liquid level surface 402 and a second liquid level surface 404 are respectively provided at the lower and upper parts of the water tank 405. A drain pipe 403 is provided on one side of the water tank 405. The table frame automated control system 8 includes a ball valve 801 and an electric ball valve 802. One end of the ball valve 801 is fixedly connected to the electric ball valve 802. The electric ball valve 802 is connected to the coaxial waterproof and sand-blocking mechanism 4 via a connecting pipe. The ball valve 801 is connected to an external water supply pipe, and the electric ball valve 802 is controlled by the automated control system to open and close the water supply. The internal cavity flushing system is divided into two lines, connected to the inner shaft flushing pipe 309 and the outer shaft flushing pipe 310 respectively. The main component of the water jet cutting liquid level management system is the water tank 405, which contains an air bladder 401. Compressed air enters and exits the air bladder through inlet / outlet pipes. When the liquid level in the water tank 405 reaches the first liquid level, the air bladder 401 inflates; when it reaches the second liquid level, water jet cutting operations can commence. When changing materials, the air bladder deflates; after replacement, the air bladder 401 inflates again, thus controlling the liquid level in the water tank 405 and facilitating the loading and unloading of materials manually or by an external robotic arm.

[0021] The coaxial waterproof and sand-blocking mechanism 4 includes a second sprocket 308, which is sleeved on one end of an inner shaft 302. The inner shaft 302 is rotatably mounted within an inner shaft sealing mechanism 305, which is housed within a mounting base 311. The mounting base 311 is located on one side of a central vertical plate 301, which is located on one side of a water tank 405. A pulley 307 is also sleeved on one end of the inner shaft 302, and an inner shaft flushing pipe is connected to one end of the inner shaft 302. In section 309, an outer shaft 303 is provided outside the inner shaft 302. An outer shaft flushing pipe 310 is provided above the intermediate vertical plate 301. An outer shaft sealing mechanism 304 is installed at one end of the outer shaft 303, and a tubular material 306 is connected to one side of the outer shaft sealing mechanism 304. Since the other ends of the inner shaft 302 and outer shaft 303, and the anti-corrosion chuck mechanism 5 are located on the right side of the intermediate vertical plate 301, i.e., inside the water tank 405 of the waterjet cutting fluid level management system 6, waterproofing and sand-blocking treatment are required. To prevent water from flowing to the left side of the intermediate vertical plate 301 and causing diamond abrasive to enter the coaxial waterproofing and sand-blocking mechanism 4 and damage precision components such as bearings, sealing mechanisms are designed at the outer shaft sealing mechanism 304 and the inner shaft sealing mechanism 305. Waterproofing is achieved using a plug seal and O-rings. To prevent diamond abrasive from damaging the plug seal and precision components such as bearings, multiple blocking rings are used to prevent diamond abrasive intrusion. The other end connects to the internal cavity flushing system 7, which effectively flushes away the diamond sand accumulated on the outer side of the sealing ring of the inner shaft 302 and the outer shaft sealing mechanism 304. The outer shaft flushing pipe 310 discharges the accumulated diamond sand directly into the water tank 405 through the internal water channel of the intermediate vertical plate 301; the inner shaft flushing pipe discharges the accumulated diamond sand into the chuck through the internal water channel of the inner shaft. The original reduction mechanism inside the chuck has been discarded, and the diamond sand is discharged into the water tank 405 through multiple sand discharge holes on the chuck, without affecting the normal operation of the jaw mechanism in the anti-corrosion chuck mechanism. All parts of the anti-corrosion chuck mechanism are made of stainless steel and will not rust.

[0022] In operation, water is first added to the water tank of the waterjet cutting fluid level management system 6, while the internal cavity flushing system operates simultaneously. Once the water level in the tank reaches the first designated position, the material is manually or via an external robotic arm to the chuck jaws and positioned. Then, the automated control system controls the chuck clamping servo drive system to clamp the material. The servo motor automatically stops after detecting that the designated torque has been reached, and simultaneously, the clutch of the external clutch reduction mechanism disengages. The chuck rotation servo drive system 2 operates, controlling the chuck to rotate the material to the designated zero position. Once this is complete, the servo motor stops. Finally, the air bladder 401 of the waterjet cutting fluid level management system 6 is inflated, and inflation stops after a certain delay. Water addition is stopped once the water level in the tank reaches the second designated position.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can exercise their rights without departing from the scope of the present invention.
