Description

[0002] A ball valve generally includes a valve body, a valve cover, a valve seat, a valve core, a valve stem and its operating mechanism. Among them, the valve core, as the main component of the ball valve to control the fluid, plays an important role. In the process of valve core processing, ball valve core processing is a key step in manufacturing ball valves. Usually, cylindrical steel blanks are selected and assembled on CNC machine tools for turning and milling. At present, there are still the following deficiencies in turning and milling ball valve cores: 1. After the ball valve core is turned, the surface of the valve core cannot be directly polished, so the valve core needs to be placed on a polishing device for processing, which makes the processing steps more complicated and is not conducive to the factory's production of the valve core; 2.

[0014] A ball valve processing method for processing raw materials into a precise spherical valve core is applied to the above-mentioned ball valve processing lathe for processing raw materials into a precise spherical valve core, and comprises the following steps: S1. First, clamp the valve core blank on the chuck, and place the required tool between the clamping plate and the mounting plate. At this time, the movable frame can be pushed to drive the two movable rods to move horizontally, and the clamping plate can be driven to approach the mounting plate. After the tool is clamped and positioned by the clamping plate, the positioning rod can be moved to a position corresponding to the positioning groove. Then, under the tension of the second tension spring in a stressed state, the positioning rod can be driven to move downward and inserted into the positioning groove, so that the tool can be stably clamped and positioned. At the same time, the bent rod is inserted into the first fixed clamp ring and stably connected to the first fixed clamp ring. At this time, the grinding rod can be installed and supported; S2. After the valve core blank is clamped on the chuck, the cover plate can be turned over to close the door hole, and then the plunger can be released.

Start the driving motor and the stepping motor at the same time. When the driving motor is started, the adjusting screw can be driven to rotate. Under the thread transmission action with the adjusting nut, the mounting plate can be driven to move longitudinally, thereby driving the tool and the grinding rod to move longitudinally. When the valve core blank is turned with the rotating valve core blank, the valve core blank can be turned into a spherical shape. At the same time, the grinding rod that can keep moving can grind the outer surface of the valve core after the valve core is turned. When the stepping motor is started, the driving screw can be driven to rotate. At this time, under the thread transmission action with the driving nut, the supporting plate can be driven to move laterally, thereby adjusting the lateral position of the tool and the grinding rod, thereby adjusting the lateral position and longitudinal position of the tool and the grinding rod, so as to turn and grind the valve core; S5. After the collection box is transferred to the base, the insert plate can be moved downward and inserted into the card hole to position the collection box, so that when the valve core is turned, the vibration generated by the motor operation will not cause the collection box to move. After the valve core processing is completed, the waste chips generated can fall on the base or fall into the collection box through the discharge hole. The waste chips fallen on the base can then be swept into the collection box so that the waste chips can be collected conveniently. After the waste chips are collected, the collection box can be moved out of the base and the waste chips can be cleaned.

[0015] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0016] Beneficial effect: In the present invention, by providing a driving mechanism, after the valve core blank is clamped on the chuck, the chuck can be driven to rotate by starting the spindle motor, and the valve core blank can be driven to rotate, so that a driving force can be provided for the valve core blank when the valve core blank is turned; In the present invention, by providing a supporting assembly, after the tool and the grinding rod are installed, the driving motor can be started to drive the adjusting screw to rotate, and under the threaded transmission action with the adjusting nut, the mounting plate can be driven to move longitudinally, thereby driving the tool and the grinding rod to move longitudinally, and when the valve core blank is turned in cooperation with the rotating valve core blank, the valve core blank can be turned into a spherical shape, and the grinding rod that can keep moving can grind the outer surface of the valve core after the valve core turning is completed; In the present invention, by setting up a power component, the transmission screw can be driven to rotate by starting the stepping motor. At this time, under the threaded transmission action with the transmission nut, the support plate can be driven to move laterally, so that the lateral position of the tool and the grinding rod can be adjusted, thereby enabling the lateral position and longitudinal position of the tool and the grinding rod to be adjusted, so as to turn and grind the valve core.

[0017] In the present invention, by setting up the collection mechanism, after the collection box is transferred to the base, the insert plate can be moved downward and inserted into the clamping hole to position the collection box, so that when the valve core is turned, the vibration generated by the operation of the motor will not cause the collection box to be displaced. After the valve core processing is completed, the waste chips generated can fall on the base or fall into the collection box through the discharge hole, and then the waste chips fallen on the base can be swept into the collection box, so that the waste chips can be conveniently collected.

[0018] When the valve core of the ball valve is turned, the present invention can grind and polish the turned valve core, thereby providing good convenience when processing the valve core, avoiding waste chips from splashing around when processing the valve core, and facilitating the collection and cleaning of the waste chips.

[0035] The present invention provides a ball valve processing method for processing raw materials into a precise spherical valve core, which is applied to the above-mentioned ball valve processing lathe for processing raw materials into a precise spherical valve core, and includes the following steps: S1. First, the valve core blank 6 is clamped on the chuck 5, and the required tool 27 is placed between the clamping plate 26 and the mounting plate 18. At this time, the movable frame 28 can be pushed to drive the two movable rods 25 to move horizontally, and the clamping plate 26 can be driven to approach the mounting plate 18. After the tool 27 is clamped and positioned by the clamping plate 26, the positioning rod 30 can be moved to the position corresponding to the positioning groove. Then, under the pulling force of the second tension spring 31 in a stressed state, the positioning rod 30 can be driven to move downward and inserted into the positioning groove, so that the tool 27 can be stably clamped and positioned. At the same time, the bent rod 34 is inserted into the first fixed clamp ring 33 and stably connected to the first fixed clamp ring 33. At this time, the grinding rod 35 can be installed and supported; S2. After the valve core blank 6 is clamped on the chuck 5, the cover plate 7 can be turned over to close the door hole, and then the plug rod 9 can be released. The first tension spring 11 in a stressed state can drive the plug rod 9 to move, so that the plug rod 9 passes through the positioning ring 10, so that the cover plate 7 can be positioned, so that when the valve core blank 6 is processed, it can prevent waste chips from flying around; S3, start the spindle motor 3 by operating the control display screen 41 to drive the chuck 5 to rotate, which can drive the valve core blank 6 to rotate, so as to provide driving force for the valve core blank 6 when turning the valve core blank 6; S4, start the driving motor 19 and the stepping motor 36 at the same time. When the driving motor 19 is started, the adjusting screw 20 can be driven to rotate. Under the threaded transmission action with the adjusting nut 22, the mounting plate 18 can be driven to move longitudinally, thereby driving the tool 27 and the grinding rod 35 to move longitudinally. When the valve core blank 6 is turned with the rotating valve core blank 6, the valve core blank 6 can be turned into a spherical shape. At the same time, the grinding rod 35 that can keep moving can grind the outer surface of the valve core after the valve core is turned. When the stepping motor 36 is started, the driving screw 37 can be driven to rotate. At this time, under the threaded transmission action with the driving nut 38, the supporting plate 14 can be driven to move laterally, thereby adjusting the lateral position of the tool 27 and the grinding rod 35, so that the lateral position and longitudinal position of the tool 27 and the grinding rod 35 can be adjusted, so as to turn and grind the valve core; S5. After the collection box 45 is transferred to the base 1, the insert plate 47 can be moved downward and inserted into the card hole to position the collection box 45, so that when the valve core is turned, the vibration generated by the operation of the motor will not cause the collection box 45 to be displaced. After the valve core processing is completed, the waste chips generated can fall on the base 1 or fall into the collection box 45 through the discharge hole. Then, the waste chips fallen on the base 1 can be swept into the collection box 45 so that the waste chips can be collected conveniently. After the waste chips are collected, the collection box 45 can be moved out of the base 1 to clean the waste chips.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the spindle motor 3, drive motor 19, stepper motor 36 and display screen 41 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.

10. A ball valve processing method for processing raw materials into a precise spherical valve core, applied to a ball valve processing lathe for processing raw materials into a precise spherical valve core as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, the valve core blank (6) is clamped on the chuck (5), and the required tool (27) is placed between the clamping plate (26) and the mounting plate (18). Then, the movable frame (28) can be pushed to drive the two movable rods (25) to move horizontally, so as to drive the clamping plate (26) to approach the mounting plate (18). After the tool (27) is clamped and positioned by the clamping plate (26), the positioning rod (30) can be moved to a position corresponding to the positioning groove. Then, under the tension of the second tension spring (31) in a stressed state, the positioning rod (30) can be driven to move downward and inserted into the positioning groove, so that the tool (27) can be stably clamped and positioned. At the same time, the bent rod (34) is inserted into the first fixed clamp ring (33) and stably connected to the first fixed clamp ring (33). Then, the grinding rod (35) can be installed and supported; S2. After the valve core blank (6) is clamped on the chuck (5), the cover plate (7) can be turned over to close the door hole, and then the insertion rod (9) can be released. The first tension spring (11) in a stressed state can drive the insertion rod (9) to move, so that the insertion rod (9) passes through the positioning ring (10), so that the cover plate (7) can be positioned, so that when the valve core blank (6) is processed, waste chips can be prevented from flying around; S3, starting the spindle motor (3) by operating the control display screen (41) to drive the chuck (5) to rotate, thereby driving the valve core blank (6) to rotate, so as to provide a driving force for the valve core blank (6) when turning the valve core blank (6); S4, simultaneously starting the drive motor (19) and the stepper motor (36), when the drive motor (19) is started, the adjusting screw (20) can be driven to rotate, and under the thread transmission action of the adjusting nut (22), the mounting plate (18) can be driven to move longitudinally, thereby driving the tool (27) and the grinding rod (35) to move longitudinally, and when the valve core blank (6) is turned to be turned into a spherical shape, the grinding rod (35) can be kept in motion. ) After the valve core is turned, the outer surface of the valve core can be polished. When the stepper motor (36) is started, the transmission screw (37) can be driven to rotate. At this time, under the threaded transmission action with the transmission nut (38), the support plate (14) can be driven to move laterally, so that the lateral position of the tool (27) and the polishing rod (35) can be adjusted, thereby enabling the lateral position and longitudinal position of the tool (27) and the polishing rod (35) to be adjusted, so as to turn and polish the valve core; S5. After the collection box (45) is transferred to the base (1), the insert plate (47) can be moved downward and inserted into the clamping hole to position the collection box (45). In this way, when the valve core is turned, the vibration generated by the operation of the motor will not cause the collection box (45) to be displaced. After the valve core is processed, the waste chips generated can fall on the base (1) or fall into the collection box (45) through the discharge hole. Thereafter, the waste chips that fall on the base (1) can be swept into the collection box (45) so that the waste chips can be collected conveniently. After the waste chips are collected, the collection box (45) can be moved out of the base (1) to clean the waste chips.
