Description

Technical Field

[0001] This invention relates to the field of casting processing equipment, and more specifically, to an integrated device for rough and finish machining of castings and its usage method. Background Technology

[0002] Ultrasonic water meters are a new type of water meter that calculates water flow rate by analyzing the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water. The characteristics of ultrasonic water meters include: low starting velocity, wide rangeability, high measurement accuracy, and stable operation. Furthermore, they have no moving parts or flow obstructions, are unaffected by impurities in the water, and have a long service life. They offer comprehensive communication functions, meeting various communication and wireless networking requirements, and possess excellent flow detection capabilities. They solve many problems associated with traditional water meters, are more suitable for tiered water pricing, and are better suited for water conservation and rational utilization, thus having a broad market and promising application prospects.

[0003] Existing ultrasonic installation pipes for ultrasonic water meter testing are all cast. After casting and demolding, the ultrasonic installation pipes require roughing and finishing processes using CNC machine tools. This involves cutting and separating the cast channels on the ultrasonic installation pipe, machining the ultrasonic water meter channel mounting thread holes, and performing other finishing processes to produce a qualified ultrasonic installation pipe. Due to limitations in processing equipment, existing ultrasonic installation pipes separate the roughing and finishing processes. Roughing is performed by clamping the pipe in one fixture, and after completion, it is removed for finishing. Then, it is clamped again in a different fixture for finishing. This significantly reduces the processing efficiency, automation level, and processing quality of the ultrasonic installation pipes, while significantly increasing the workload and labor costs.

The end fastening mounting component is mounted on a multi-axis rotary table, and the machining end fastener is mounted on the end fastening mounting component. Alternatively, the multi-axis rotary table can be a four-axis or a five-axis rotary table, whichever is selected according to the machining requirements. The multi-axis rotary table is mounted on the worktable of a CNC machine tool.

[0046] The end fastening mounting component includes a fastening mounting base 1, a fastening mounting transmission component, and a fastening mounting power component. The fastening mounting base 1 is disposed on the multi-axis rotary table, and both the fastening mounting transmission component and the fastening mounting power component are disposed on the fastening mounting base 1. The fastening mounting base 1 is rectangular in shape and has mounting holes to facilitate mounting the fastening mounting base 1 on the multi-axis rotary table.

[0047] The fastening and installation transmission components include a first fastening and installation transmission component and a second fastening and installation transmission component 2, both of which are mounted on the fastening and installation base 1. The first fastening and installation transmission component includes a fastening transmission tube 3, a fastening transmission shaft 4, and a fastening transmission rod 5. The outer wall of the fastening transmission tube 3 is fixedly mounted on one end of the fastening and installation base 1. Further, two fastening transmission tubes 3 are provided, symmetrically spaced at one end of the fastening and installation base 1. The two ends of the fastening transmission shaft 4 are respectively and rotatably fitted into the two fastening transmission tubes 3. One end of the fastening transmission rod 5 is vertically fixed on the fastening transmission shaft 4 between the two fastening transmission tubes 3. Further, a thrust ball bearing 6 is provided between one end of the fastening transmission tube 3 and the side wall of the fastening transmission rod 5, so that the fastening transmission shaft 4 is axially locked during stable circumferential rotation within the fastening transmission tube 3. To improve the stability of the fastening transmission rod 5.

[0048] The second fastening and mounting transmission component 2 has the same structure as the first fastening and mounting transmission component. The second fastening and mounting transmission component 2 is disposed on the other end of the fastening and mounting base 1, and the second fastening and mounting transmission component 2 is symmetrical to the first fastening and mounting transmission component.

[0049] The fastening and mounting power components include a first fastening and mounting power component and a second fastening and mounting power component 7, both of which are mounted on the fastening and mounting base 1. The first fastening and mounting power component includes a first motor 8, a first worm gear 9, and a first worm wheel 10. The first motor 8 is fixedly mounted on the fastening and mounting base 1, the first worm gear 9 is mounted on the first motor 8, and the first worm wheel 10 is fixedly mounted on the fastening transmission shaft 4, meshing with the first worm gear 9 to provide power for the fastening transmission rod 5 to swing as driven by the fastening transmission shaft 4. The second fastening and mounting power component 7 has the same structure as the first fastening and mounting power component, and is connected and driven by the second fastening and mounting transmission component 2 to provide power for the swinging of the fastening transmission rod 5 of the second fastening and mounting transmission component 2.

[0050] The processing end fasteners include a first end fastener and a second end fastener 11. The first end fastener is disposed on the first fastening and mounting transmission member, and the second end fastener 11 is disposed on the second fastening and mounting transmission member 2. The first end fastener includes an internal fastening limiting member and an external fastening limiting member. The internal fastening limiting member is disposed on the first fastening and mounting transmission member, and the external fastening limiting member is disposed on the internal fastening limiting member.

[0051] The internal fastening and limiting component includes an internal fastening support, an internal limiting lock, and an internal limiting power component. The internal fastening support is mounted on the first fastening and installation transmission component, and both the internal limiting lock and the internal limiting power component are mounted on the internal fastening support. The internal fastening support includes an internal limiting support tube 12, which is a thick-walled tube with an outer diameter smaller than the inner diameter of the ultrasonic installation pipe 13 to be processed (the ultrasonic installation pipe 13 is a cast part). One end of the internal limiting support tube 12 is horizontally fixed to the other end of the fastening transmission rod 5, providing support for the internal limiting lock and the internal limiting power component. Furthermore, a limiting through hole is provided on the side wall of one end of the internal limiting support tube 12. The limiting through hole is rectangular, and multiple limiting through holes are evenly distributed around the internal limiting support tube 12.

[0052] The internal limiting and locking component includes an internal limiting component and an internal locking limiting component, both of which are disposed on the internal fastening support component. The internal limiting component includes an internal limiting block 15 and an internal limiting transmission component, both of which are disposed on the internal limiting support tube 12.

[0053] The internal limiting block 15 is a right-angled trapezoidal block. The inclined end of the internal limiting block 15 is axially slidably embedded into the limiting through-hole and extends into the internal limiting support tube 12. The axial direction of the internal limiting block 15 is perpendicular to the axis of the internal limiting support tube 12. Furthermore, the right-angled end face of the internal limiting block 15 is rounded to increase the frictional contact area between the right-angled end face of the internal limiting block 15 and the inner wall of the ultrasonic installation pipe 13 to be processed, thereby improving the stability of the internal limiting block 15 in limiting the ultrasonic installation pipe. Multiple internal limiting blocks 15 correspond one-to-one with multiple limiting through-holes to improve limiting stability. Alternatively, the internal limiting block 15 is made of a ferromagnetic material.

[0054] The internal limiting transmission component includes a limiting transmission push cone 16 and a transmission screw 17. One end of the limiting transmission push cone 16 is shaped like a frustum of a cone, and the other end is cylindrical. The diameter of the other end of the limiting transmission push cone 16 is not greater than the inner diameter of the internal limiting support tube 12. The limiting transmission push cone 16 is axially slidably embedded in one end of the internal limiting support tube 12, and the conical surface of one end of the limiting transmission push cone 16 mates with the arc surface on the inclined surface of the internal limiting block 15. This allows the limiting transmission push cone 16 to push the internal limiting block 15 outward when it slides axially within the internal limiting support tube 12, thereby limiting and locking the ultrasonic installation pipe 13 from inside the pipe, facilitating rough and fine machining of the cast ultrasonic installation pipe 13 by CNC machine tool tools. The transmission screw 17 is threaded, and one end of the transmission screw 17 is fitted into a threaded hole in the limiting transmission push cone 16. The threaded hole mates with the transmission screw 17, and the axis of the threaded hole coincides with the axis of the limiting transmission push cone 16. When the transmission screw 17 rotates, it pushes the limiting transmission push cone 16 to slide axially within the internal limiting support tube 12 through the threaded hole. Furthermore, the limiting transmission push cone 16 is magnetic and can attract the internal limiting block 15.

[0055] The internal locking and limiting component includes a limiting transmission rod 18, a circumferential locking seat 19, and a circumferential locking member. One end of the limiting transmission rod 18 is horizontally fixed to the other end of the transmission screw 17. The circumferential locking seat 19 is cylindrical, and a locking through hole is provided at the axis of the circumferential locking seat 19. The circumferential locking seat 19 is fixedly fitted onto the limiting transmission rod 18 through the locking through hole, and the outer wall of the circumferential locking seat 19 is circumferentially slidably embedded in the axial limiting groove on the inner wall of the internal limiting support tube 12. The axial limiting groove is annular, allowing the circumferential locking seat 19 to rotate circumferentially and lock axially within the axial limiting groove. The circumferential locking member locks the circumferential locking seat 19 circumferentially within the internal limiting support tube 12, further improving the limiting stability of the ultrasonic installation pipe 13 and improving the machining accuracy of the CNC machine tool. Furthermore, a locking hole is provided on the outer wall of the circumferential locking seat 19.

[0056] The circumferential locking component includes a first magnetic coil and a first locking shaft 21. The first magnetic coil is fixedly embedded in a spiral groove on the inner wall of the locking hole, and the first locking shaft 21 is axially slidably embedded in the locking hole. When a direct current is applied to the first magnetic coil to generate a magnetic field, it will push the first locking shaft 21 to move axially within the locking hole, thereby pushing one end of the first locking shaft 21 into the locking groove on the bottom surface of the axial limiting groove, so as to circumferentially lock the circumferential locking seat 19 within the axial limiting groove.

[0057] Alternatively, multiple locking holes are provided, evenly distributed around the circumferential locking seat 19, and multiple circumferential locking members are sequentially disposed within the multiple locking holes. Multiple locking grooves are provided, evenly distributed circumferentially within the axial limiting groove, and the number of locking grooves is greater than the number of locking holes, ensuring that for every certain rotation angle, at least one set of the first locking shaft 21 of the circumferential locking members is inserted into one locking groove, thus satisfying the circumferential locking function of the circumferential locking seat 19.

[0058] The internal limiting power component includes a second motor 22, which is fixedly mounted on the internal limiting support tube 12. The free end of the rotating shaft of the second motor 22 is fixedly connected to the other end of the limiting transmission rod 18. This drives the limiting transmission rod 18 to rotate circumferentially. The circumferentially rotating limiting transmission rod 18 drives the transmission screw 17 to rotate. The rotating transmission screw 17 drives the limiting transmission push cone 16 to slide axially through the threaded hole, thereby limiting and locking the ultrasonic installation pipe 13 onto the internal limiting block 15.

[0059] The external fastening and limiting component includes an external limiting power component, an external limiting fastener, and an external limiting lock component. The external limiting power component is disposed on the internal fastening support component, and both the external limiting fastener and the external limiting lock component are disposed on the external limiting power component. The external limiting power component includes a stabilizing tube 23, a third motor 24, and a limiting screw 25. One end of the stabilizing tube 23 is vertically fixed to the outer wall of the internal limiting support tube 12. The third motor 24 is fixed to the fastening transmission rod 5. One end of the limiting screw 25 is fixed to the rotating shaft of the third motor 24, and the other end of the limiting screw 25 is rotatably embedded in the other end of the stabilizing tube 23.

[0060] The external limiting fastener includes a limiting transmission seat 26 and a limiting seat 27. The limiting transmission seat 26 is a threaded tubular shape and is fitted onto the limiting screw 25. The internal thread of the inner wall of the limiting transmission seat 26 engages with the limiting screw 25. Alternatively, a sliding block is provided on the outer wall of the limiting transmission seat 26, which is fitted into a sliding groove on the side wall of the fastening transmission rod 5. This allows the limiting transmission seat 26 to slide up and down along the sliding groove, driven by the rotating limiting screw 25. The limiting seat 27 is a right-angled block shape, with one right-angled side fixedly mounted on the side wall of the limiting transmission seat 26 and moving with it. The right-angled inner side wall of the limiting seat 27 is used to limit the flange 14 at one end of the ultrasonic installation pipe 13. It should be noted that the inner wall of one right-angled side of the limiting seat 27 is limited and fitted to the end face of the flange 14, and the inner wall of the other right-angled side of the limiting seat 27 is limited and fitted to the cut surface on the outer wall of the flange 14.

[0061] The external limiting and locking component includes a locking tube 28, a second magnetic coil, and a second locking shaft. One end of the locking tube 28 is horizontally inserted through the other end of the stabilizing tube 23. The second magnetic coil is fixedly embedded in a spiral groove on the inner wall of the locking tube 28. The second locking shaft is axially slidably embedded in the locking tube 28, and the second locking shaft can correspond to a limiting locking groove on the outer wall of one end of the limiting screw 25. When a direct current is applied to the second magnetic coil to generate a magnetic field, it will push the second locking shaft to slide axially within the locking tube 28, thereby inserting one end of the second locking shaft into the limiting locking groove to circumferentially lock the limiting screw 25, thereby improving the limiting stability of the limiting seat 27 on the flange 14. Furthermore, multiple limiting locking grooves are provided, and the multiple limiting locking grooves are evenly distributed circumferentially around the limiting screw 25.

[0062] The second end fastener 11 has the same structure as the first end fastener. The second end fastener 11 is symmetrical to the first end fastener on the second fastening and mounting transmission member 2. The connection method between the second end fastener 11 and the second fastening and mounting transmission member 2 is the same as the connection method between the first end fastener and the first fastening and mounting transmission member, so as to limit and lock the two ends of the ultrasonic installation pipe 13 respectively, thereby improving the machining accuracy of CNC machine tools.
