Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of gas pressure reducer processing, in particular to a gas pressure reducer shell processing tool and a processing method thereof. Background Art
[0002] A gas pressure reducer is a precision control device used to reduce the pressure of high-pressure gas (such as high-pressure gas in oxygen cylinders and nitrogen cylinders) and stably output it to the required low pressure. Its core function is to reduce the input high-pressure gas (usually up to 10-30MPa) to the low pressure required by the equipment (such as 0.1-1MPa) by adjusting the coordination between the internal valve core and the spring, and to maintain the stability of the output pressure when the gas source pressure fluctuates or the gas consumption changes.
[0003] The gas pressure reducer housing machining tooling is a special fixture device used to assist in the positioning, clamping and precision control of the gas pressure reducer housing (mostly made of metal) during the machining process. This tooling is widely used in the mass production of pressure reducers, can improve processing efficiency and reduce scrap rate, and is an important process equipment to ensure the dimensional accuracy, sealing performance and overall reliability of the gas pressure reducer housing.
[0004] In the field of reducing pressure housing processing, the single-sided clamping design of the current mainstream tooling has significant defects, which directly affects the processing accuracy and yield rate of the product. When fixing the reducing pressure housing, this type of tooling generally adopts a single-direction clamping method, either using an external circumferential chuck for radial clamping or using an internal circumferential tensioning mechanism to achieve fixation, resulting in the housing being subjected to uneven stress during processing. When the tooling applies a unilateral clamping force to the outer or inner circumference of the shell, the clamping part becomes the only force-bearing point, generating local stress concentration under the dual effects of cutting force and clamping force. For thin-walled pressure reducer shells (usually with a wall thickness of 2-5mm), this concentrated stress can easily cause plastic deformation at the clamping part, resulting in out-of-tolerance dimensional accuracy and form and position tolerances of the shell, leading to increased precision differences among products in the same batch, making it difficult to meet the strict requirements of the pressure reducer for sealing performance and pressure regulation stability. To this end, we propose a tooling and processing method for gas pressure reducer shells. Summary of the Invention
[0005] In response to the shortcomings of the existing technology, the present invention provides a gas pressure reducer shell processing tool and a processing method thereof, which solves the problem that when the existing gas pressure reducer processing tool applies a unilateral clamping force to the outer circumference or inner circumference of the shell, the clamping part becomes the only force point, and local stress concentration is generated under the dual action of cutting force and clamping force. For thin-walled pressure reducer shells (wall thickness is usually 2-5mm), this concentrated stress can easily cause plastic deformation of the clamping part, resulting in out-of-tolerance dimensional accuracy and form and position tolerances of the shell, resulting in increased precision differences among products in the same batch, making it difficult to meet the strict requirements of the pressure reducer for sealing performance and pressure regulation stability.

[0014] Preferably, the top of the telescopic sleeve is conical, the inner diameter of the fixing ring is smaller than the outer diameter of the piston, and the lower surface of the mounting seat is provided with an inverted U-shaped groove for placing the exhaust pipe and the intake pipe. The fixing ring can be used to limit the range of motion of the piston within the sleeve to ensure the stability of the piston during use.
[0015] Preferably, S1, when using a processing tool, the processing tool is installed on equipment including but not limited to cutting equipment for processing the gas pressure reducer housing, and a solenoid valve is installed on the outlet of the exhaust pipe. After completing the installation of the processing tool, the pressure reducer housing to be processed is fixed in a designated processing area using a first clamping device and a second clamping device; S2. When placing the pressure reducer housing, the pressure reducer housing first contacts the telescopic sleeve in the expanded state. Guided by the tapered portion of the telescopic sleeve, the pressure reducer housing is centrally placed on the surface of the telescopic sleeve. When the pressure reducer housing fully applies its own weight to the telescopic sleeve, the telescopic sleeve pushes the piston downward under the action of gravity. The piston moves downward under the guidance of the sleeve to assist the telescopic sleeve in guiding the movement direction of the pressure reducer housing. At the same time, the solenoid valve on the exhaust pipe opens. During the movement, the piston squeezes the gas in the sleeve, causing the gas in the sleeve to be discharged through the exhaust pipe. When the piston moves to the lowest position, the pressure reducer housing is initially restrained on the mounting seat. S3. When the reducer housing presses down the telescopic sleeve by its own weight, the reducer housing gradually approaches the protective pad. When the reducer housing contacts the protective pad, the reducer housing presses down the extrusion rod, which pushes the wedge block. The wedge block pulls the reset spring, which is squeezed and deformed. During the downward movement, the wedge block contacts the inclined surface of the slider and cooperates with the slider to push the assembly frame. The assembly frame pushes the stop block, which pushes the rubber pad 2. During the movement, the rubber pad 2 gradually approaches the inner wall of the reducer housing. When the reducer housing contacts the upper surface of the mounting seat, the rubber pad 2 abuts against the inner wall of the reducer housing, and cooperates with the stop block and other structures to clamp the reducer housing from the inside. S4. After the second clamping device completes the preliminary clamping of the pressure reducer housing, the motor cooperates with the linkage rod to drive the worm, the worm is meshed with the worm wheel, the worm wheel rotates under the action of the worm, and cooperates with the connecting disk to rotate the pressure ring. When the pressure ring rotates, the protrusion on its inner wall is displaced, and in the process of movement, it pushes the connecting column, which squeezes the load spring. The load spring is squeezed and deformed. Under the action of the pressure ring, the connecting column cooperates with the assembly frame to push the splint, and the splint pushes the rubber pad 1. The rubber pad 1 gradually approaches the pressure reducer housing. When the rubber pad 1 contacts the pressure reducer housing, the motor stops running. Then, under the self-locking characteristics of the worm and the worm wheel, the pressure ring cooperates with the connecting column, the assembly frame, the splint and the rubber pad 1 to clamp the pressure reducer housing from the outside; S5. After the pressure reducer housing is fixed, the cutting device is turned on and controlled to perform cutting on the pressure reducer housing. The device cuts the exterior of the pressure reducer housing, thereby reducing the material of the pressure reducer housing at the designed position, so that the outer shape of the pressure reducer housing reaches the designed shape. S6. After the pressure reducer housing is cut, the motor is controlled to work. The motor cooperates with the linkage rod to drive the worm to reverse, and the worm drives the worm wheel. The worm wheel rotates the pressure ring in cooperation with the connecting plate, and the pressure ring protrusion rotates away from the connecting column. When the connecting column loses the restraint of the pressure ring, the connecting column loses the pressure applied to the load spring. The load spring rebounds and pushes the connecting column to reset. Then, the pressure ring, the connecting column, and the clamping plate and rubber pad positioned by the assembly frame stop clamping the pressure reducer housing. S7. When the first clamping device stops clamping and the pressure reducer housing needs to be removed from the telescopic sleeve, the solenoid valve is closed and the air pump is turned on. The air pump is powered on to pump external air into the sleeve, and the air pressure in the sleeve increases. At the same time, the piston in the sleeve pushes the telescopic sleeve upward under the action of the gas, and the telescopic sleeve is forced to lift the pressure reducer housing; S8. When the guiding device lifts up the pressure reducer housing, the pressure reducer housing stops applying pressure to the extrusion rod, the extrusion rod stops applying pressure to the wedge block, the wedge block stops pulling the reset spring, the reset spring loses pressure and rebounds and pulls the wedge block to reset, the wedge block lifts up the extrusion rod when resetting, and cooperates with the connecting rope to pull the slider, the slider pulls the assembly frame, the block and the rubber pad to reset step by step, when the pressure reducer housing is removed, the second clamping device is completely reset, and then the processing tooling can be recycled.
[0016] In summary, the technical effects and advantages of the present invention are: 1. In the present invention, by providing a first clamping device and a second clamping device, the processing tool can clamp the pressure reducer housing in the processing state from the outer wall and the inner wall of the pressure reducer housing at the same time, so that the clamping part is effectively supported, avoiding the problem of deformation of the pressure reducer housing caused by unilateral clamping, so that the processing tool can ensure that the accuracy of the same batch of products is within the design error range, so as to meet the sealing requirements of the pressure reducer housing in subsequent use.
[0017] 2. In the present invention, a guiding device is used so that when the user places the pressure reducer housing, the housing moves along the designed moving path, thereby avoiding the problem of the pressure reducer housing being offset during the placement process and interfering with subsequent processing. At the same time, it can effectively ensure that the housing is located in the designed center position after placement. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the friction coefficient of the contact surface with the pressure reducer housing 51 can be increased, thereby improving the clamping stability of the pressure reducer housing 51.
[0023] Among them, the surface of the connecting column 29 is fixedly connected with a shielding plate 213 for shielding the slot of the mounting seat 21.

The fixing ring 44 can be used to limit the range of movement of the piston 42 within the sleeve 41 to ensure the stability of the piston 42 during use.
[0030] The working principle of the present invention is as follows: when using a processing tool, the processing tool is installed on equipment used to process the gas pressure reducer housing, including but not limited to cutting equipment, and a solenoid valve is installed at the outlet of the exhaust pipe 45. After the processing tool is installed, the pressure reducer housing to be processed is fixed in a designated processing area using the first clamping device 2 and the second clamping device 3; When placing the pressure reducer housing 51, the pressure reducer housing 51 first contacts the telescopic sleeve 43 in the expanded state. Under the guidance of the tapered portion of the telescopic sleeve 43, the pressure reducer housing 51 is centrally sleeved on the surface of the telescopic sleeve 43. When the pressure reducer housing 51 fully applies its own weight to the telescopic sleeve 43, the telescopic sleeve 43 pushes the piston 42 downward under the action of gravity. The piston 42 moves downward under the guidance of the sleeve 41 to assist the telescopic sleeve 43 in guiding the movement direction of the pressure reducer housing 51. At the same time, the solenoid valve on the exhaust pipe 45 is opened. During the movement, the piston 42 squeezes the gas in the sleeve 41, so that the gas in the sleeve 41 is discharged through the exhaust pipe 45. When the piston 42 moves to the lowest position, the pressure reducer housing 51 is initially restrained on the mounting seat 21. When the reducer housing 51 presses down the telescopic sleeve 43 by its own weight, the reducer housing 51 gradually approaches the protective pad 33. When the reducer housing 51 contacts the protective pad 33, the reducer housing 51 presses down the extrusion rod 32. The extrusion rod 32 pushes the wedge block 34. The wedge block 34 pulls the return spring 35. The return spring 35 is squeezed and deformed. In the process of moving downward, the wedge block 34 contacts the inclined surface of the slider 36 and cooperates with the slider 36 to push the assembly frame 37. The assembly frame 37 pushes the stop block 38. The stop block 38 pushes the rubber pad 2 39. In the process of movement, the rubber pad 2 39 gradually approaches the inner wall of the reducer housing 51. When the reducer housing 51 contacts the upper surface of the mounting seat 21, the rubber pad 2 39 presses against the inner wall of the reducer housing 51 to cooperate with the stop block 38 and other structures to clamp the reducer housing 51 from the inside. After the second clamping device 3 completes the preliminary clamping of the pressure reducer housing 51, the motor 22 cooperates with the linkage rod 23 to drive the worm 25, the worm 25 engages with the worm wheel 26, and the worm wheel 26 rotates under the action of the worm 25 and cooperates with the connecting plate 27 to rotate the pressure ring 28. When the pressure ring 28 rotates, the protrusion on its inner wall is displaced and pushes the connecting column 29 during the movement. The connecting column 29 squeezes the load spring 214, and the load spring 214 is squeezed and deformed, and the connecting column 29 Under the action of the pressure ring 28, the assembly frame 210 pushes the clamping plate 211, and the clamping plate 211 pushes the rubber pad 1 212. The rubber pad 1 212 gradually approaches the pressure reducer housing 51. When the rubber pad 1 212 contacts the pressure reducer housing 51, the motor 22 stops running. Then, under the self-locking characteristics of the worm 25 and the worm wheel 26, the pressure ring 28 cooperates with the connecting column 29, the assembly frame 210, the clamping plate 211 and the rubber pad 1 212 to clamp the pressure reducer housing 51 from the outside. After the pressure reducer housing is fixed, the cutting device is turned on and controlled to perform cutting processing on the pressure reducer housing. The device cuts the outside of the pressure reducer housing, thereby reducing the material of the pressure reducer housing at the designed position, so that the outer shape of the pressure reducer housing reaches the designed shape; After the pressure reducer housing 51 is cut, the motor 22 is controlled to work. The motor 22 cooperates with the linkage rod 23 to drive the worm 25 to reverse, and the worm 25 drives the worm gear 26. The worm gear 26 rotates the pressure ring 28 in cooperation with the connecting plate 27. The protrusion of the pressure ring 28 rotates away from the connecting column 29. When the connecting column 29 loses the restriction of the pressure ring 28, the connecting column 29 loses the pressure applied to the load spring 214. The load spring 214 loses the pressure and rebounds, pushing the connecting column 29 to return to its original position. Then, the clamping plate 211 and the rubber pad 212 positioned by the pressure ring 28, the connecting column 29 and the assembly frame 210 stop clamping the pressure reducer housing 51. When the first clamping device 2 stops clamping and the pressure reducer housing 51 needs to be removed from the telescopic sleeve 43, the solenoid valve is closed, the switch of the air pump 47 is turned on, and the air pump 47 is energized to pump external air into the sleeve 41. The air pressure in the sleeve 41 increases, and at the same time, the piston 42 located in the sleeve 41 pushes the telescopic sleeve 43 upward under the action of the gas. The telescopic sleeve 43 is forced to lift the pressure reducer housing 51. The guide device 4 allows the user to place the pressure reducer housing on the designed moving path, so that the pressure reducer housing is prevented from being offset during the placement process, which interferes with subsequent processing. At the same time, it can effectively ensure that the housing is located in the designed center position after placement; When the guide device 4 lifts up the pressure reducer housing 51, the pressure reducer housing 51 stops applying pressure to the extrusion rod 32, the extrusion rod 32 stops applying pressure to the wedge block 34, and the wedge block 34 stops pulling the return spring 35. The return spring 35 loses pressure and rebounds and pulls the wedge block 34 to reset. The wedge block 34 lifts up the extrusion rod 32 when resetting, and cooperates with the connecting rope 310 to pull the slider 36. The slider 36 pulls the assembly frame 37, the block 38 and the rubber pad 39 to gradually reset. When the pressure reducer housing 51 is removed, the second clamping device 3 is completely reset, and the processing tool can be recycled. By providing the first clamping device 2 and the second clamping device 3, the processing tool can clamp the pressure reducer housing in the processing state from the outer wall and the inner wall of the pressure reducer housing at the same time, so that the clamping part is effectively supported, avoiding the problem of deformation of the pressure reducer housing caused by unilateral clamping, so that the processing tool can ensure that the accuracy of products in the same batch is within the design error range, so as to meet the sealing requirements of the pressure reducer housing in subsequent use.

After completing the installation of the processing tool, the pressure reducer housing to be processed is fixed in a designated processing area using a first clamping device (2) and a second clamping device (3); S2. When placing the pressure reducer housing (51), the pressure reducer housing (51) first contacts the telescopic sleeve (43) in the expanded state. Under the guidance of the tapered portion of the telescopic sleeve (43), the pressure reducer housing (51) is centrally sleeved on the surface of the telescopic sleeve (43). When the pressure reducer housing (51) fully applies its own weight to the telescopic sleeve (43), the telescopic sleeve (43) pushes the piston (42) downward under the action of gravity. The piston (42) moves downward under the guidance of the sleeve (41) to assist the telescopic sleeve (43) in guiding the movement direction of the pressure reducer housing (51). At the same time, the solenoid valve on the exhaust pipe (45) is opened. The piston (42) squeezes the gas in the sleeve (41) during the movement, so that the gas in the sleeve (41) is discharged through the exhaust pipe (45). When the piston (42) moves to the lowest position, the pressure reducer housing (51) is initially restricted on the mounting seat (21); S3. When the reducer housing (51) presses down the telescopic sleeve (43) by its own weight, the reducer housing (51) gradually approaches the protective pad (33). When the reducer housing (51) contacts the protective pad (33), the reducer housing (51) presses down the extrusion rod (32). The extrusion rod (32) pushes the wedge block (34). The wedge block (34) pulls the return spring (35). The return spring (35) is squeezed and deformed. In the process of moving downward, the wedge block (34) is in contact with the inclined surface of the slider (36).

When the rubber pad (212) contacts the pressure reducer housing (51), the motor (22) stops running, and then under the self-locking characteristics of the worm (25) and the worm wheel (26), the pressure ring (28) cooperates with the connecting column (29), the assembly frame (210), the clamping plate (211) and the rubber pad (212) to clamp the pressure reducer housing (51) from the outside; S5. After the pressure reducer housing is fixed, the cutting device is turned on and controlled to perform cutting on the pressure reducer housing. The device cuts the exterior of the pressure reducer housing, thereby reducing the material of the pressure reducer housing at the designed position, so that the outer shape of the pressure reducer housing reaches the designed shape.

The worm wheel (26) rotates the pressure ring (28) in cooperation with the connecting plate (27), and the pressure ring (28) protrusion rotates away from the connecting column (29). When the connecting column (29) loses the restriction of the pressure ring (28), the connecting column (29) loses the pressure applied to the load spring (214), and the load spring (214) loses the pressure and rebounds, and pushes the connecting column (29) to reset, and then stops clamping the pressure reducer housing (51) through the clamping plate (211) and the rubber pad (212) positioned by the pressure ring (28), the connecting column (29) and the assembly frame (210); S7, when the first clamping device (2) stops clamping and the pressure reducer housing (51) needs to be removed from the telescopic sleeve (43), the solenoid valve is closed, the switch of the air pump (47) is turned on, the air pump (47) is energized to pump external gas into the sleeve (41), the air pressure in the sleeve (41) increases, and at the same time, the piston (42) located in the sleeve (41) pushes the telescopic sleeve (43) upward under the action of the gas, and the telescopic sleeve (43) is forced to lift the pressure reducer housing (51); S8.
