Automatic rotating equipment for processing waterproof and sand-blocking tubular material

Abstract

The invention belongs to the technical field of material processing, and relates to a waterproof and sand-blocking tubular material processing automatic rotating device which comprises a chuck clamping servo driving system, a coaxial waterproof and sand-blocking mechanism is installed on one side of a water cutting liquid level management system and connected to a chuck rotating servo driving system, and the chuck rotating servo driving system is connected with the coaxial waterproof and sand-blocking mechanism. And an anti-corrosion chuck mechanism is mounted on one side of the coaxial waterproof sand blocking mechanism. According to the device, a speed reducing mechanism which is originally used for torque amplification in the chuck is arranged to be transferred to the outside of the chuck. Due to the fact that the whole chuck and materials are immersed in water, and the speed reducing mechanism is a precise transmission mechanism, if the speed reducing mechanism is arranged in the chuck, the speed reducing mechanism can be corroded by water and influenced by carborundum, bad influences such as mechanism clamping stagnation and transmission failure are caused, and even the structure is damaged, and the speed reducing mechanism is not influenced when transferred to the outside of the chuck. And finally, the power amplified by the speed reducer is transmitted to the coaxial waterproof sand blocking mechanism through a chain wheel and a chain.

Description

Technical Field

[0001] The invention belongs to the technical field of material processing, and in particular relates to an automatic rotating device for processing tubular materials capable of waterproofing and blocking sand. Background Art

[0002] When using water jet cutting to obtain parts in the circumferential direction of tubular materials, the tubular materials are first decomposed along the axial direction, then placed flat on the material table, and finally the parts are obtained using the traditional method. This not only destroys the original shape of the material, but also takes time and effort, and wastes materials. Cutting directly on the tubular material, due to the curvature limitation of the tubular material, not only is the working area of ​​the water jet cutting narrow, but also the material needs to be rearranged after each processing before it can be processed again. This is inefficient and cannot be processed in the circumferential direction. When processing the circumferential direction of the tubular material, the material can be clamped on the chuck, and the indexing disk can be manually rotated to a certain angle for processing again after each processing. Although this can ensure the accuracy of the equal division processing, the chuck is submerged in water and is very easy to rust and corrode. Precision parts such as bearings will also be corroded and affected by diamond abrasive, reducing their life or even damage. Summary of the invention

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

[0004] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: an automated rotating equipment for processing tubular materials that can prevent water and sand, including a chuck clamping servo drive system, one end of the chuck clamping servo drive system is installed with an external clutch reduction device, one end of the external clutch reduction device is installed with a chuck rotation servo drive system, the chuck clamping servo drive system, the chuck rotation servo drive system and the lower surface of the external clutch reduction device are fixedly connected with a table frame automation control system, one side of the table frame automation control system is fixedly connected with a water cutting liquid level management system, one side of the water cutting liquid level management system is installed with a coaxial waterproof and sand retaining mechanism, the coaxial waterproof and sand retaining mechanism is connected to the chuck rotation servo drive system, and one side of the coaxial waterproof and sand retaining mechanism is installed with an anti-corrosion chuck mechanism.

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

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

[0007] Preferably, the table frame automation control system includes a ball valve and an electric ball valve, one end of the ball valve is fixedly connected to the electric ball valve, and the electric ball valve is connected to the coaxial waterproof sand retaining mechanism through a connecting pipe.

[0008] Preferably, the coaxial waterproof sand retaining mechanism comprises a No. 2 sprocket, the No. 2 sprocket is sleeved on one end of the inner shaft, the inner shaft is rotatably mounted in an inner shaft sealing mechanism, and the inner shaft sealing mechanism is arranged in a mounting seat.

[0009] Preferably, the mounting seat is arranged on one side of the middle vertical plate, the middle vertical plate is arranged on one side of the water tank, one end of the inner shaft is also sleeved with a pulley, one end of the inner shaft is connected to an inner shaft flushing pipeline, and an outer shaft is arranged outside the inner shaft.

[0010] Preferably, an outer shaft flushing pipeline is arranged above the middle vertical 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] The present invention transfers the speed reduction mechanism that originally amplifies the torque inside the chuck to the outside of the chuck. Because the entire chuck and the material are submerged in water, and the speed reduction mechanism is a precision transmission mechanism, if the speed reduction mechanism is set inside the chuck, it will be affected by water rust and corundum, causing adverse effects such as mechanism jamming and transmission failure, and even damage to the structure. The speed reduction mechanism will not be affected by the above when it is transferred to the outside of the chuck. Finally, the power amplified by the speed reducer is transmitted to the coaxial waterproof sand retaining mechanism through the sprocket chain.

[0012] The inner cavity flushing and cleaning system of the present invention is divided into two routes, which are respectively connected to the inner shaft flushing pipeline and the outer shaft flushing pipeline. The main body of the water cutting liquid level management system is a water tank, and an air bag is installed inside the water tank. Compressed air enters and exits the air bag through the air bag inlet / exhaust pipeline. When the liquid level in the water tank reaches the first liquid level surface, the air bag is inflated, and when it reaches the second liquid level surface, the water cutting operation can be officially carried out. When replacing materials, the air bag is exhausted, and after the replacement is completed, the air bag is inflated again, so as to achieve the purpose of controlling the height of the water tank liquid level, which is convenient for manual or external manipulators to load and unload materials.

[0013] In the present invention, since the other ends of the inner shaft and the outer shaft and the anti-corrosion chuck mechanism are on the right side of the middle vertical plate, that is, inside the water tank in the water jetting level management system, waterproof and sand-blocking treatment is required. In order to prevent water from flowing to the left side of the middle vertical plate and corundum from entering the coaxial waterproof and sand-blocking mechanism to damage precision parts such as bearings, sealing mechanisms are designed at the outer shaft sealing mechanism and the inner shaft sealing mechanism. Waterproofing uses a pan seal and an O-ring for sealing, and multi-channel blocking rings are used to prevent corundum from damaging pan seals and precision parts such as bearings. The other end is connected to the inner cavity flushing and cleaning system, which can effectively flush the corundum accumulated on the outside of the blocking ring of the inner shaft and outer shaft sealing mechanism. The outer shaft flushing pipeline passes through the internal waterway of the middle vertical plate to discharge the accumulated corundum directly into the water tank; the inner shaft flushing pipeline passes through the internal waterway of the inner shaft to discharge the accumulated corundum into the chuck. The original speed reduction mechanism inside the chuck has been discarded, and the diamond sand is discharged to the water tank through multiple sand discharge holes on the chuck, which will not affect the normal operation of the claw mechanism in the anti-corrosion chuck mechanism. All parts of the anti-corrosion chuck mechanism are made of stainless steel and will not rust. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation

[0016] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0017] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0018] like Figures 1 to 4 As shown, an embodiment of the present invention provides an automatic rotating device for processing tubular materials capable of waterproofing and sand blocking, comprising a chuck clamping servo drive system 1, one end of which is equipped with an external clutch reduction device 3, one end of which is equipped with a chuck rotation servo drive system 2, 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 are fixedly connected with a table frame automation control system 8, one side of the table frame automation control system 8 is fixedly connected with a waterjet liquid level management system 6, one side of the waterjet liquid level management system 6 is installed with a coaxial waterproof sand blocking mechanism 4, the coaxial waterproof sand blocking mechanism 4 is connected to the chuck rotation servo drive system 2, and one side of the coaxial waterproof sand blocking mechanism 4 is installed with an anti-corrosion chuck mechanism 5, firstly, water is added to the water tank of the waterjet liquid level management system 6, and at the same time, the inner cavity flushing and cleaning system works. After the water level in the water tank reaches the first designated position, the material is moved to the chuck claw position manually or by an external manipulator and positioned. Then the automatic control system controls the chuck clamping servo drive system to clamp the material. The servo motor stops automatically after detecting that the specified torque has been reached, and the clutch of the external clutch reduction mechanism is disengaged. The chuck rotation servo drive system 2 works to control the chuck to drive the material to rotate to the specified zero position. After completion, the servo motor stops. Finally, the airbag 401 of the water jet cutting liquid level management system 6 is inflated, and the inflation stops after a certain delay. Stop adding water after the liquid level in the water tank reaches the second specified position.

[0019] The chuck rotation servo drive system 2 includes a servo motor 201, the output shaft of the servo motor 201 is equipped with a clutch 202, one end of the clutch 202 is equipped with a speed reduction mechanism 203, and one end of the speed reduction mechanism 203 is equipped with a sprocket 204, so that the speed reduction mechanism that originally amplifies the torque inside the chuck is transferred to the outside of the chuck. Because the entire chuck and the material are submerged in water, and the speed reduction mechanism 203 is a precision transmission mechanism, if the speed reduction mechanism 203 is set inside the chuck, it will be affected by water rust and diamond sand, causing adverse effects such as mechanism jamming and transmission failure, and even damage to the structure. The speed reduction mechanism is transferred to the outside of the chuck and will not be affected by the above. Finally, the power amplified by the speed reducer is transmitted to the coaxial waterproof sand retaining mechanism through the sprocket chain.

[0020] The coaxial waterproof sand retaining mechanism 4 includes an airbag 401, and there are several airbags 401, each of which is fixedly connected to one side of the inner wall of the water tank 405. The first liquid level surface 402 and the second liquid level surface 404 are respectively arranged at the bottom and the top of the water tank 405. A drainage pipeline 403 is arranged at one side of the water tank 405. The table frame automatic 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 sand retaining mechanism 4 through a connecting pipe. The ball valve 801 is connected to the external water supply pipeline, and the electric ball valve 802 is controlled by the automatic control system to open and close the waterway. The inner cavity flushing and cleaning system is divided into two ways, which are respectively connected to the inner shaft flushing pipeline 309 and the outer shaft flushing pipeline 310. The main body of the water jet cutting liquid level management system 6 is a water tank 405, and an air bag 401 is installed inside the water tank 405. Compressed air enters and exits the air bag through the air bag inlet / exhaust pipeline. When the liquid level in the water tank 405 reaches the first liquid level, the air bag 401 is inflated, and when it reaches the second liquid level, the water jet cutting operation can be officially carried out. When the material is replaced, the air bag is exhausted, and after the replacement is completed, the air bag 401 is inflated again, so as to achieve the purpose of controlling the height of the liquid level in the water tank 405, which is convenient for manual or external manipulators to load and unload materials.

[0021] The coaxial waterproof sand retaining mechanism 4 includes a second sprocket 308, which is sleeved on one end of the inner shaft 302. The inner shaft 302 is rotatably mounted in the inner shaft sealing mechanism 305. The inner shaft sealing mechanism 305 is arranged in a mounting seat 311. The mounting seat 311 is arranged on one side of the middle vertical plate 301. The middle vertical plate 301 is arranged on one side of the water tank 405. One end of the inner shaft 302 is also sleeved with a pulley 307. One end of the inner shaft 302 is connected to an inner shaft flushing pipe The outer shaft 303 is arranged outside the inner shaft 302, and the outer shaft flushing pipeline 310 is arranged above the middle vertical plate 301. The outer shaft sealing mechanism 304 is installed at one end of the outer shaft 303, and the 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 the outer shaft 303 and the anti-corrosion chuck mechanism 5 are on the right side of the middle vertical plate 301, that is, in the water tank 405 in the water jet cutting liquid level management system 6, waterproof and sand blocking treatment is required. In order to prevent water from flowing to the left side of the middle vertical plate 301 and diamond sand from entering the coaxial waterproof and sand blocking mechanism 4 to damage precision parts such as bearings, sealing mechanisms are designed at the outer shaft sealing mechanism 304 and the inner shaft sealing mechanism 305. Waterproofing adopts pan seal and O-ring for sealing, and multi-blocking rings are used to prevent diamond sand from damaging pan seal and precision parts such as bearings. The other end is connected to the inner cavity flushing cleaning system 7, which can effectively flush the corundum accumulated on the outer side of the inner shaft 302 and the outer shaft sealing mechanism 304. The outer shaft flushing pipeline 310 directly discharges the corundum accumulated on the outer side of the blocking ring through the internal water channel of the middle vertical plate 301 to the water tank 405; the inner shaft 302 flushing pipeline discharges the accumulated corundum into the chuck through the internal water channel of the inner shaft. The original speed reduction mechanism inside the chuck has been abandoned, and the corundum is discharged to the water tank 405 through multiple sand discharge holes on the chuck, which will not affect the normal operation of the claw 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] When in use, first add water to the water tank of the water cutting liquid level management system 6, and at the same time, the inner cavity flushing and cleaning system works. After the liquid level in the water tank reaches the first designated position, the material is manually or externally moved to the chuck claw position and positioned. Then the automatic control system controls the chuck clamping servo drive system to clamp the material. The servo motor stops automatically after detecting that the specified torque has been reached, and at the same time, the clutch of the external clutch reduction mechanism is disengaged. The chuck rotation servo drive system 2 works to control the chuck to drive the material to rotate to the specified zero position. After completion, the servo motor stops. Finally, the airbag 401 of the water cutting liquid level management system 6 is inflated, and the inflation is stopped after a certain delay. Stop adding water after the liquid level in the water tank reaches the second designated position.

[0023] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent will not depart from the scope of the technical solution of the present invention.
