Description

Technical Field

[0001] The invention relates to the technical field of valve sleeve production, and in particular to a press-fitting device for producing a liquid return valve sleeve. Background Art

[0002] The return valve sleeve is mainly used to control the unidirectional flow of fluid. During the production process, the return valve sleeve usually adopts a hollow tube made of stainless steel, carbon steel or alloy steel. First, the hollow tube is processed, and then cut into the shape of the valve sleeve according to the set size and shape. When the hollow tube is processed on the machine tool, a bar feeder is usually required to press and clamp the hollow tube on the spindle, and then turn, grind, cut, drill and other operations are performed.

[0003] A Chinese patent with publication number CN219325066U discloses a stainless steel pipe processing and grinding mechanism, including a machine body, a water tank is arranged at the bottom of an operating table, a circulating water pump is arranged at the top of the machine body, a water pipe is arranged below the circulating water pump, a nozzle is arranged below the water pipe, a first motor is arranged on the right side of the circulating water pump, a first connecting rod is arranged below the first motor, a rotating wheel is arranged below the first connecting rod, a fixing plate is arranged on the right side of the machine body, a second motor is arranged on the right side of the fixing plate, a second connecting rod is arranged on the left side of the fixing plate, a polishing wheel is arranged at the left end of the second connecting rod, a grinding wheel is arranged on the left side of the polishing wheel, bolts are arranged inside the fixing plate, and fixing rings are arranged outside the polishing wheel and the grinding wheel; by arranging the circulating water pump and the nozzle, the steel pipe can be cooled to avoid damage to the steel pipe caused by excessive temperature; by arranging the first motor and the rotating wheel, the device can automatically pull the steel pipe, thereby reducing labor intensity.

[0004] In the above technology, the stainless steel pipe is fixed and transported by two wheels during the processing. Since the stainless steel pipe is hollow, the water will spray out from one end of the stainless steel pipe when spraying water, which is easy to spray on the work surface and the ground, causing environmental pollution. Iron filings are also sprayed out with the water. The iron filings flow onto the work surface and are easy to get stuck in the transmission structure, causing the transmission mechanism to get stuck. When cleaning, the small iron filings may injure the operator's hands, posing a safety hazard. Summary of the invention

Detailed implementation manners

[0017] The present invention will be further described below in conjunction with the drawings and embodiments.

[0018] Please refer to Figure 1-8 , the present invention provides a technical solution for a press-fitting device for the production of a liquid return valve sleeve: Embodiment

[0019] According to Figure 1 and Figure 2As shown in the figure, a press-fitting device for the production of a liquid return valve sleeve includes a workbench 1 and a pipe body 3 to be processed. At one end of the top of the workbench 1, a mounting seat 2 is vertically and fixedly installed. One end of the pipe body 3 is inserted into the interior of the mounting seat 2, and a positioning mechanism for fixing the pipe body 3 is arranged inside the mounting seat 2; on the other side of the workbench 1, there is a conveying body 6. A L-shaped plate is fixedly welded on the side wall of the conveying body 6 away from the workbench 1. A second cylinder 5 is horizontally fixedly connected to the conveying body 6 through the L-shaped plate. The output end of the second cylinder 5 is fixedly connected with a movable cylinder 4. A clamping mechanism is arranged inside the movable cylinder 4, which is used to sleeve and fix the other end inside the pipe body 3 during use, facilitating stable conveying. The pipe body 3 is conveyed to the middle position of the conveying body 6 by the conveying body 6. At this time, the centers of the pipe body 3, the second cylinder 5, and the mounting seat 2 are all on the same straight line. One side of the workbench 1 is slidably connected with a moving frame 7 through an electric slide rail (not shown in the attached figure). A processing equipment main body 71 is installed on the moving frame 7, and the processing equipment main body 71 is arranged beside the pipe 3. When the processing equipment main body 71 is in use, it is used for processing the pipe body 3. The processing equipment main body 71 can be set as single-head or multi-head, facilitating turning, grinding, cutting, drilling, etc. of the pipe body 3.

[0020] Since the pipe body 3 needs to rotate during processing and the pipe body 3 needs to be retracted to the conveying body 6 for conveying after processing by the second cylinder 5, the movable cylinder 4 should be clamped and fixed to one end of the pipe body 3. Specifically, as Figure 6 and Figure 7 shown, a first motor 44 is fixedly connected to the inner wall of the movable cylinder 4. The output shaft of the first motor 44 is fixedly connected with a reciprocating lead screw 42. A circular plate 43 is fixedly connected to the inner wall of the movable cylinder 4. The two ends of the reciprocating lead screw 42 are respectively rotationally connected to the circular plate 43 and the movable cylinder 4 through bearings. A moving block 45 is threadedly connected to the reciprocating lead screw 42. A plurality of limiting ports 47 are opened on the side wall of the movable cylinder 4 close to the pipe body 3. An L-shaped support block 41 is slidably connected in each limiting port 47. The inner end of the L-shaped support block 41 is rotationally connected to a connecting rod 46 through a pin shaft. The other end of the connecting rod 46 is rotationally connected to the moving block 45 through a pin shaft, and anti-slip threads are provided on the outer walls of the L-shaped support blocks 41. By starting the first motor 44, the output shaft of the first motor 44 drives the reciprocating lead screw 42 to rotate. The reciprocating lead screw 42 drives the moving block 45 to move. The moving block 45 drives one end of the connecting rod 46 to move. The connecting rod 46 pushes the L-shaped support block 41 to move. Since the L-shaped support block 41 slides on the limiting port 47 and both ends of the connecting rod 46 are provided with pin shafts for rotation, the connecting rod 46 drives the L-shaped support block 41 to slide along the sliding port 26. When the L-shaped support block 41 is in close contact with the inner wall of the pipe body 3, the pipe body 3 can be clamped and fixed by the L-shaped support block 41, facilitating driving the pipe body 3 to move; when the L-shaped support block 41 is not in contact with the inner wall of the pipe body 3, it is convenient for the separation of the movable cylinder 4 and the pipe body 3.

[0021] An external gear ring 51 is fixedly connected to the outer wall of the movable cylinder 4. The end of the output end of the second cylinder 5 is fixedly connected with a connecting plate 53. A second motor 54 is installed on the connecting plate 53. A gear 52 is fixedly sleeved on the output shaft of the second motor 54, and the gear 52 meshes with the external gear ring 51. When the pipe body 3 needs to be rotated, by turning on the second motor 54, the output shaft of the second motor 54 drives the gear 52 to rotate. The gear 52 drives the external gear ring 51 to rotate. The external gear ring 51 drives the movable cylinder 4 to rotate. The movable cylinder 4 drives the pipe body 3 to rotate by driving the L-shaped support block 41, achieving the processing effect on different positions of the pipe body 3.

[0022] Such as Figure 4 As shown in the figure, a through hole is provided in the mounting seat 2. A ring plate 210 is fixedly sleeved on the inner side wall of the through hole. Four tooth columns 24 are rotatably connected to the side wall of the ring plate 210 close to the rubber plug plate 28 through rotating shafts. The four tooth columns 24 are circumferentially distributed at equal intervals in the through hole. An internal gear ring 25 is also rotatably connected to the inner side wall of the through hole through a bearing. The four tooth columns 24 are all meshed with the internal gear ring 25. Four sliding ports 26 are provided in the mounting seat 2 through the through hole. Four racks 22 are slidably connected in the through hole of the mounting seat 2 through the sliding ports 26 in a directional manner, and the four racks 22 are respectively meshed with the four tooth columns 24 at corresponding positions; A limiting roller 23 is installed at the inner end of each rack 22. The limiting rollers 23 are evenly arranged in a circumferential manner on the outer side of the end of the pipe body 3. The pipe body 3 can be clamped and fixed through the limiting rollers. A first cylinder 21 is fixedly installed on the top of the mounting seat 2. The output end of the first cylinder 21 movably penetrates through the through hole and is fixedly connected to the top of the rack 22 located above.

[0023] When the pipe body 3 is press-fitted, if it is directly press-fitted into the main shaft, a large force is required both when inserting and removing, which not only reduces the working efficiency but also reduces the service life of the second cylinder 5. Therefore, the second cylinder 5 drives one end of the pipe body 3 to move into the through hole of the mounting seat 2. Then, the first cylinder 21 is turned on. The output end of the first cylinder 21 drives the connected rack 22 to move. When the rack 22 moves, the driving force is transmitted through the meshing with the corresponding tooth column 24 to drive the connected tooth column 24 to rotate. When the tooth column 24 rotates, it can drive the internal gear ring 25 to rotate. The internal gear ring 25 drives several other tooth columns 24 to rotate. The several other tooth columns 24 drive several other racks 22 to move, so as to drive the four racks 22 to move synchronously. The racks 22 drive the connected limiting rollers 23 to move inward until the pipe body 3 is clamped and fixed in the mounting seat 2 through the limiting rollers 23. When the pipe body 3 moves in the mounting seat 2, the limiting rollers 23 roll on the surface of the pipe body 3, playing a role of limiting and guiding, and achieving the precise positioning of the pipe body 3.

[0024] During specific use, for the press-fitting device for producing a liquid return valve sleeve according to the present invention, first, the conveying body 6 conveys the pipe body 3 to the middle position of the processing table, making it correspond to the axis of the workbench. Then, the second cylinder 5 pushes the movable cylinder 4 forward to extend into the rear end of the pipe body 3. Next, the first motor 44 is started, and the output shaft of the first motor 44 drives the reciprocating lead screw 42 to rotate. The reciprocating lead screw 42 drives the movement of the moving block 45. Through the movement cooperation of the moving block 45 and the connecting rod 46, the L-shaped support block 41 is driven to move outward and expand. After the L-shaped support block 41 is in close contact with the inner wall of the pipe body 3, the pipe body 3 is clamped and fixed by the L-shaped support block 41. Then, the second cylinder 5 continues to push the pipe body 3 forward until the front end of the pipe body 3 is inserted into the through hole. Then, the first cylinder 21 is started, and the output end of the first cylinder 21 drives the connected rack 22 to move. When the rack 22 moves, it drives the connected tooth column 24 to rotate. Through the mutual meshing and transmission force of the rack 22, the tooth column 24 and the internal gear ring 25, all the racks 22 are driven to move synchronously closer to the center of the through hole. The rack 22 drives the connected limiting roller 23 to move until the pipe body 3 is positioned in the mounting seat 2, realizing the press-fitting and clamping of the pipe body 3. Then, the pipe body 3 is processed by the main body 71 of the processing equipment. When it is necessary to rotate the pipe body 3, the second motor 54 is started, and the output shaft of the second motor 54 drives the gear 52 to rotate. The gear 52 drives the external gear ring 51 to rotate. The external gear ring 51 drives the movable cylinder 4 to rotate. The movable cylinder 4 drives the pipe body 3 to rotate through the L-shaped support block 41, realizing the processing effect on different positions of the pipe body 3. When the processing of the pipe body 3 is completed, the clamping mechanism releases the front end of the pipe body 3, and the second cylinder 5 retracts. The pipe body 3 is driven by the L-shaped support block 41 of the movable cylinder 4 to retreat to the conveying body 6 and is conveyed forward. Embodiment

[0025] On the basis of Embodiment 1, during the processing, it is necessary to cool down and clean the pipe body 3. Therefore, a high-pressure nozzle 72 is installed on the moving frame 7. The high-pressure nozzle 72 is arranged near the main body 71 of the processing equipment, and the water spraying direction faces the processing position of the processing equipment. The high-pressure nozzle 72 is connected to an external water source through a water pipe, and the high-pressure nozzle 72 moves with the movement of the main body 71 of the processing equipment. During the processing of the pipe body 3, the high-pressure nozzle 72 is started to spray water on the pipe body 3 to cool down and clean the pipe body 3. Sprayed on the pipe body 3 by the high-pressure nozzle 72, it can not only clean the iron filings on the surface but also cool down, realizing the cooling and protection effect on the pipe body 3.

[0026] A water through hole 11 is provided at a position outside the mounting seat on the workbench 1. The water through hole 11 is arranged below the end of the pipe body 3. A plurality of filter holes 12 are provided on the processing surface of the workbench 1. A collection box 14 is arranged at the bottom of the workbench 1. The collection box 14 is arranged below the workbench 1 in an inverted conical structure. The water through hole 11 and the filter holes 12 are both communicated with the collection box 14. The collection box is used to receive the water left on the workbench 1. A protective frame 13 is arranged around the processing surface of the workbench 1; When the water through hole 11 and the filter holes 12 are in use, by providing the water through hole 11, it is convenient for the water to flow out at one end of the pipe body 3. By providing the filter holes 12, it is convenient for the processing debris and the sprayed water to flow out. By providing the collection box 14, it is convenient for the recycling of waste water and debris. By providing the protective frame 13, the spraying of waste water and debris is reduced. Embodiment

[0027] On the basis of Embodiment 2, when the outer surface of the pipe body 3 is being polished, in order to prevent debris or the water sprayed by the high-pressure nozzle 72 from splashing into the inside of the pipe body 3 from both ends of the pipe body 3 and being difficult to clean; or when the inner wall of the pipe body 3 is being processed, in order to prevent the water inside the pipe body 3 from flowing out directly, a plugging mechanism is also provided. The plugging mechanism is arranged at one end of the pipe body 3 and is used to plug the end of the pipe body; as Figure 2 and Figure 3 shown, the plugging mechanism includes a pen-shaped cylinder 27, a swivel joint 29 and a rubber plugging plate 28. The pen-shaped cylinder 27 is fixedly connected to the side wall of the mounting seat 2 away from the pipe body 3. The output end of the pen-shaped cylinder 27 is fixedly connected with the swivel joint 29. A rubber plugging plate 28 is rotatably connected to the swivel joint 29 through a rotating shaft, and the rubber plugging plate 28 can be closely attached to the end of the pipe body 3.

[0028] When the inner wall of the pipe body 3 of the liquid return valve sleeve is being processed, the processing equipment main body 71 and the high-pressure nozzle 72 are located inside the pipe body 3. The pipe body 3 is processed by the processing equipment main body 71. During the processing, it is necessary to turn on the high-pressure nozzle 72 to spray water on the pipe body 3 to cool and clean the pipe body 3. When spraying water, the water flow is likely to spray out from one end of the pipe body 3 and splash on the workbench 1 and the ground, causing environmental pollution. When the plugging mechanism provided by the present invention is in use, the pen-shaped cylinder 27 is turned on. The output end of the pen-shaped cylinder 27 drives the swivel joint 29 to move. The swivel joint 29 drives the rubber plugging plate 28 to move. The swivel joint 29 and the rubber plugging plate 28 plug one end of the pipe body 3, so that when the pipe body 3 is being processed, the high-pressure water flushing the pipe body 3 will not spray out from the inside of the pipe body 3. After the processing is completed, the swivel joint 29 and the rubber plugging plate 28 leave the pipe body 3 under the drive of the pen-shaped cylinder 27. The waste liquid inside the pipe body 3 flows through the tail of the pipe body 3 into the water through hole 11 and finally into the collection box 14; When the outer wall of the pipe body 3 of the liquid return valve sleeve is processed, the main body 71 of the processing equipment and the high-pressure nozzle 72 are located outside the pipe body. When the high-pressure nozzle 72 sprays water, the water flow is likely to splash into the inside of the pipe body 3, making it difficult to clean the inside of the pipe body. When the plugging mechanism provided by the present invention is in use, the output end of the pen-shaped cylinder 27 drives the adapter 29 to move, the adapter 29 drives the rubber plug plate 28 to move, and the adapter 29 and the rubber plug plate 28 block one end of the pipe body 3, so that when the pipe body 3 is processed, the high-pressure water flushing the pipe body 3 will not splash into the pipe body 3.

[0029] Embodiment 4: On the basis of Embodiment 1, this embodiment further introduces the conveying body 6.

[0030] As Figure 1 shown, a baffle 61 is rotatably connected to the conveying body 6 through a pin shaft. The baffle 61 is arranged along the telescopic direction of the second cylinder 5, and a driving motor is provided at one end of the pin shaft.

[0031] The baffle 61 provided in this embodiment is used to position the pipe body 3 during use, ensuring that the center line of the pipe body 3 coincides with the center line of the second cylinder 5. The conveying body 6 is a small body and is arranged on one side of the bar feeder. The bar feeder feeds materials one by one at one end of the conveying body 6. At the same time, the other end of the conveying body 6 is used to convey the processed pipe body 3, improving work efficiency. Embodiment

[0032] On the basis of Embodiment 1, in order to further improve the stability of the pipe body 3 when moving towards the mounting seat 2, as Figures 1 to 2 shown, two third cylinders 8 are vertically installed on the processing surface of the workbench 1. The upper output end of the third cylinder 8 is fixedly connected with a V-shaped plate 81. A plurality of guide rollers 82 are rotatably connected to the inner side wall of the V-shaped plate 81. The V-shaped block provided by the present invention is used to convey the pipe body 3 during use. By turning on the third cylinder 8, the V-shaped pipe is adjusted to a suitable height to ensure that the pipe body 3 is horizontally conveyed along the center during pushing, preventing the pipe body 3 from falling during pushing, and reducing the friction of the pipe body 3 during conveying under the action of the guide rollers 82.

[0033] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
