Description

Technical Field

[0001] This invention relates to the field of lathe technology, and in particular to a lathe for manufacturing valves that integrates chip isolation and collision prevention. Background Technology

[0002] The steam-water system of a thermal power generating unit consists of a boiler, turbine, condenser, high and low pressure heaters, condensate pumps, and feedwater pumps. It includes steam-water circulation, chemical water treatment, and cooling systems. Water is heated into steam in the boiler, and after being further heated by the heaters, it becomes superheated steam. It then enters the turbine through the main steam pipeline. As the steam expands continuously, the high-speed flowing steam drives the turbine blades to rotate, thereby driving the generator.

[0003] A large number of valves are used in thermal power generating units, and during valve production, the end faces of the valves need to be machined on a lathe. In traditional machining, the sharp chips generated during turning are very easy to fly or fall onto the machined surface of the valve, especially the internal channels or sealing surfaces, or the area to be machined, causing surface scratches, reduced accuracy, or affecting the sealing performance of subsequent assembly. Furthermore, multi-faceted, intermittent turning is prone to vibration, causing the clamped valve to deflect or loosen slightly, resulting in unexpected contact between the tool and the workpiece, and thus risks such as tool collisions. This can damage the workpiece and tool, or even damage the machine tool. To solve these problems, frequent machine stops are usually required to clean up the chips or inspect or reposition the workpiece, which seriously hinders machining efficiency and continuity. Therefore, it not only affects the quality of valve machining, but also has a serious impact on the efficiency of valve machining. Summary of the Invention

[0004] The purpose of this invention is to provide a lathe for valve production that integrates chip isolation and collision prevention, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A lathe for manufacturing valves that integrates debris isolation and collision prevention includes a lathe body and a valve.

A contact locking frame is slidably mounted on the fixture platform. Each of the two sliding strips has a locking groove. The contact locking frame is locked in the two locking grooves and is in contact with the valve.

[0006] Furthermore, in a preferred embodiment of the present invention, the debris isolation device further includes a synchronous drive frame, which is mounted on two of the sliding isolation frames; A connecting mounting base is installed on the auxiliary fixture platform, and a rotating drive frame is rotatably mounted on the connecting mounting base. The rotating drive frame is movably mounted on the synchronous drive frame.

[0007] Furthermore, in a preferred embodiment of the present invention, two linkage shafts are installed on the rotation drive frame, and one of the linkage shafts is movably installed inside the synchronous drive frame; The connecting mounting base has a pull-back groove, and another linkage shaft is rotatably installed in the pull-back groove. A pull-back torsion spring is installed on the inner wall of the pull-back groove and is mounted on the linkage shaft.

[0008] Furthermore, in a preferred embodiment of the present invention, a transition push plate is slidably mounted on one side of the auxiliary fixture table, and a push rod is mounted on the transition push plate. The movement of the transition push plate drives the rotating frame to rotate through the push rod. A synchronous pull-down bracket is slidably installed on one side of the fixture table. Three extrusion wedge blocks are installed on the synchronous pull-down bracket. A push sliding hole is opened on the adapter push plate. A push sliding shaft is inserted into the push sliding hole and the push sliding shaft is installed on the synchronous pull-down bracket. The auxiliary fixture platform is provided with a limiting groove, the synchronous pull-down bracket is movably installed in the limiting groove, and a spreading spring is installed on the inner wall of the limiting groove. The spreading spring is installed on the synchronous pull-down bracket.

[0009] Furthermore, in a preferred embodiment of the present invention, a movable baffle is rotatably mounted on the sliding isolation frame, a spring-loaded groove is provided on the movable baffle, a spring-loaded rotating shaft is rotatably mounted in the spring-loaded groove, and the spring-loaded rotating shaft is mounted on the sliding isolation frame; A spring is installed on the inner wall of the spring groove, and the spring is mounted on the spring shaft.

[0010] Furthermore, in a preferred embodiment of the present invention, the valve sliding device further includes two squeezing pushers, both of which are slidably mounted on the bottom side of the contact locking frame, and a pull-down bracket is movably mounted on one of the squeezing pushers; Each of the three cutting tools is fitted with a connecting ring, and the three connecting rings are in contact with the two extrusion pushers and the pull-down bracket, respectively.

[0011] Furthermore, in a preferred embodiment of the present invention, a return spring is installed on the pull-down bracket, and the return spring is installed on the inner wall of one of the compression push brackets; A pull-back spring is installed on the extrusion pusher, and the pull-back spring is installed on the inner wall of the contact locking frame.

[0012] Furthermore, in a preferred embodiment of the present invention, a sliding spring is installed on the sliding strip, and the sliding spring is installed on the inner wall of the fixture table; A buffer spring is installed on the contact locking frame, and the buffer spring is installed on the inner wall of the fixture table.

[0013] Furthermore, in a preferred embodiment of the present invention, an end-sealing device is also included, which is installed on the debris isolation device and is used to seal the end of the valve; The end sealing device further includes two adapter mounting seats, which are respectively mounted on the two positioning isolation frames. A sealing shaft is rotatably mounted on the adapter mounting seat, and a sealing plate is mounted on one end of the sealing shaft.

[0014] Furthermore, in a preferred embodiment of the present invention, a push lever is installed on the closed rotating shaft, and a trigger pusher is installed on the sliding isolation frame. The movement of the sliding isolation frame drives the trigger pusher to push the push lever to rotate. The adapter mounting base has a mounting groove, the closed rotating shaft is rotatably mounted in the mounting groove, a closed torsion spring is installed on the inner wall of the mounting groove, and the closed torsion spring is mounted on the closed rotating shaft.

[0015] The beneficial effects of the lathe for valve manufacturing that integrates debris isolation and collision prevention proposed in this invention are: In this invention, by setting up a chip isolation device, when three moving tool holders drive three cutting tools to process the valve on the fixture table, the synchronous drive frame drives two sliding isolation frames to slide, thereby allowing the sliding isolation frames to combine with the positioning isolation frames to seal the end faces of the valve. When the two end faces of the valve are sealed, three relatively enclosed spaces are formed, so that the chips generated during the processing of the three end faces of the valve are isolated and will not interfere with each other. Therefore, the sliding partition forms a physical barrier during processing, effectively preventing chip splashing and falling into the critical areas of the valve, protecting the surface finish and precision of the processed surface, reducing the scrap rate, and avoiding secondary cutting damage to the cutting edge of the tool by chips. It also reduces or even eliminates downtime caused by chip cleaning, enabling more continuous turning operations. At the same time, it effectively controls the range of chip splashing, helps to keep the machine tool working area relatively clean, and improves the operating environment.

[0016] Furthermore, in this invention, by setting up a valve sliding device, during the valve processing, when the valve vibrates excessively or the cutting tool deflects during processing, the contact locking frame moves downward and disengages from the two sliding strips. Then, under the tension of the two sliding springs, the two sliding strips drive the auxiliary fixture table to slide out of the fixture table. This achieves real-time monitoring of the valve position. Once abnormal deflection caused by vibration is detected, the fixture is immediately triggered to move downward, allowing the workpiece to quickly escape from the possible collision path with the cutting tool. This proactively avoids serious tool collision accidents, protects the workpiece, cutting tool, and machine tool, significantly extends the service life of the cutting tool and the machine tool spindle, and avoids time losses and production interruptions caused by tool collisions, such as repairing and replacing workpieces and cutting tools. Moreover, the chip isolation and anti-collision protection process is fully automated, requiring no manual intervention, reducing the burden on operators, and is more in line with the development trend of intelligent manufacturing.

[0017] Furthermore, in this invention, by setting the end sealing device, when the sliding isolation frame and the positioning isolation frame are combined, the sliding isolation frame drives the trigger push frame to push the push lever to rotate. The push lever drives the sealing rotating plate to rotate through the sealing rotating shaft. At the same time, the sealing rotating shaft rotates in the mounting groove, and the sealing torsion spring is stressed. When the sealing rotating plate rotates, the end face of the valve is exposed, which is convenient for processing. When the valve is clamped, the sealing rotating plate seals the end face of the valve, avoiding the problem of the valve being hit by the cutting tool and damaged during clamping.

[0025] Please refer to the attached instruction manual. Figures 1-13 The present invention provides a lathe for manufacturing valves that integrates chip isolation and collision prevention, comprising a lathe body 1 and a valve 3. A fixture table 2 is mounted on the lathe body 1, and an auxiliary fixture table 10 is movably mounted on the fixture table 2. The valve 3 is clamped on the auxiliary fixture table 10. Three movable tool holders 4 are slidably mounted on the lathe body 1. A cutting tool 5 for machining the valve 3 and a clamping cylinder 6 for clamping the valve 3 are mounted on the movable tool holders 4.

[0026] Further, please refer to the appendix to the instruction manual. Figures 2-9The present invention provides a lathe for manufacturing valves with integrated chip isolation and anti-collision functions, which further includes a chip isolation device 7. The chip isolation device 7 is installed on an auxiliary fixture table 10, which is used to seal both ends of the valve 3. Specifically, the chip isolation device 7 includes two sliding isolation frames 701, both of which are slidably installed on the auxiliary fixture table 10. Two positioning isolation frames 702 are installed on the auxiliary fixture table 10. Both ends of the valve 3 are respectively locked in the two positioning isolation frames 702. The two sliding isolation frames 701 are in contact with the two positioning isolation frames 702 to isolate both ends of the valve 3. It should be noted that in this embodiment of the invention, when the three movable tool holders 4 drive the three cutting tools 5 to process the valve 3 on the fixture table 2, the sliding isolation frame 701 and the positioning isolation frame 702 are combined to seal the end face of the valve 3. When the two end faces of the valve 3 are sealed, three relatively closed spaces are formed, so that the debris generated during the processing of the three end faces of the valve 3 is isolated and will not interfere with each other, thereby ensuring the production quality of the valve 3.

[0027] More specifically, in this embodiment of the invention, a valve sliding device 8 is also included. The valve sliding device 8 is mounted on the fixture table 2, and an auxiliary fixture table 10 is mounted on the valve sliding device 8. The valve sliding device 8 is used to drive the auxiliary fixture table 10 to slide out of the fixture table 2. The valve sliding device 8 includes two sliding strips 801, both of which are slidably mounted on the fixture table 2. The auxiliary fixture table 10 is mounted on the two sliding strips 801. A contact locking frame 803 is slidably mounted on the fixture table 2. Each of the two sliding strips 801 has a locking groove 805. The contact locking frame 803 is locked in the two locking grooves 805 and is in contact with the valve 3. It should be noted that, in this embodiment of the invention, during the processing of valve 3, if valve 3 vibrates excessively or cutting tool 5 vibrates excessively, the contact locking frame 803 will move downward, thereby unlocking the sliding strip 801. This will enable the valve 3 to be quickly separated from the cutting tool 5 in an emergency, thus avoiding affecting the processing quality of valve 3.

[0028] Furthermore, the lathe for manufacturing valves that integrates chip isolation and anti-collision functions provided in this embodiment of the invention includes a chip isolation device 7 that further comprises a synchronous drive frame 704, which is mounted on two sliding isolation frames 701. A connecting mounting base 707 is mounted on the auxiliary fixture table 10, and a rotating drive frame 705 is rotatably mounted on the connecting mounting base 707. The rotating drive frame 705 is movably mounted on the synchronous drive frame 704. It should be noted that in this embodiment of the invention, when the moving tool holder 4 moves, the synchronous drive frame 704 drives the two sliding isolation frames 701 to slide, thereby achieving the purpose of actively isolating the valve 3.

[0029] Please continue to refer to the instruction manual appendix. Figures 2-9 More specifically, in this embodiment of the invention, two linkage shafts 706 are installed on the rotation drive frame 705, and one linkage shaft 706 is movably installed in the synchronous drive frame 704. Furthermore, a pull-back groove 708 is provided on the connecting mounting base 707, and the other linkage shaft 706 is rotatably installed in the pull-back groove 708. A pull-back torsion spring 709 is installed on the inner wall of the pull-back groove 708, and the pull-back torsion spring 709 is installed on the linkage shaft 706. It should be noted that in this embodiment of the invention, when the rotation drive frame 705 rotates, one linkage shaft 706 rotates within the pull-back groove 708, causing the pull-back torsion spring 709 to be stressed. Simultaneously, the rotation of the rotation drive frame 705 drives the synchronous drive frame 704 to move via the other linkage shaft 706, thereby achieving the purpose of driving the two sliding isolation frames 701 to slide via the synchronous drive frame 704 when the rotation drive frame 705 rotates.

[0030] More specifically, in this embodiment of the invention, a transition push plate 710 is slidably installed on one side of the auxiliary fixture table 10, and a push connecting rod 711 is installed on the transition push plate 710. The movement of the transition push plate 710 drives the rotation of the drive frame 705 through the push connecting rod 711. A synchronous pull-down frame 712 is slidably installed on one side of the fixture table 2. Three extrusion wedge blocks 715 are installed on the synchronous pull-down frame 712, and a push sliding hole 713 is opened on the transition push plate 710. A push sliding shaft 714 is inserted into the push sliding hole 713 and is installed on the synchronous pull-down frame 712. In addition, a limiting groove 716 is provided on the auxiliary fixture table 10, and the synchronous pull-down bracket 712 is movably installed in the limiting groove 716. A spreading spring 717 is installed on the inner wall of the limiting groove 716 and is installed on the synchronous pull-down bracket 712. It should be noted that, in this embodiment of the invention, when the moving knife holder 4 moves, it pushes the extrusion wedge block 715 to move, causing the extrusion wedge block 715 to drive the synchronous pull-down bracket 712 to move downward. The synchronous pull-down bracket 712 moves vertically within the limiting groove 716, causing the spreading spring 717 to contract under force. At the same time, the movement of the synchronous pull-down bracket 712 drives the push sliding shaft 714 to move within the push sliding hole 713, thereby driving the adapter push plate 710 to move laterally. The lateral movement of the adapter push plate 710 drives the push connecting rod 711 to push the rotating drive frame 705 to rotate. The rotation of the rotating drive frame 705 drives the synchronous drive frame 704 to move, causing the synchronous drive frame 704 to drive the two sliding isolation frames 701 to slide, thereby achieving the purpose of automatic sliding of the two sliding isolation frames 701.

[0031] More specifically, in this embodiment of the invention, a movable baffle 703 is rotatably mounted on the sliding isolation frame 701. A spring-loaded groove 718 is formed on the movable baffle 703, and a spring-loaded shaft 719 is rotatably mounted within the spring-loaded groove 718. The spring-loaded shaft 719 is mounted on the sliding isolation frame 701. Furthermore, a spring-loaded torsion spring 720 is mounted on the inner wall of the spring-loaded groove 718, and the spring-loaded torsion spring 720 is mounted on the spring-loaded shaft 719. It should be noted that in this embodiment of the invention, when the auxiliary fixture table 10 slides out or resets, the movable baffle 703 is rotated by the cutting tool 5. The movable baffle 703 rotates on the spring-loaded shaft 719 via the spring-loaded groove 718, causing the spring-loaded torsion spring 720 to be stressed. When the movable baffle 703 leaves the cutting tool 5, the rotational force of the spring-loaded torsion spring 720 helps the movable baffle 703 reset, thereby automatically maintaining the isolation effect on debris.

[0032] Please refer to the instruction manual attached. Figures 2-3 and Figures 10-11 Furthermore, the lathe for manufacturing valves that integrates debris isolation and anti-collision provided in this embodiment of the invention includes a valve sliding device 8 that further includes two extrusion pushers 806. Both extrusion pushers 806 are slidably mounted on the bottom side of the contact locking frame 803, and a pull-down frame 809 is movably mounted on one of the extrusion pushers 806. In addition, each of the three cutting tools 5 is fitted with a retaining ring 808, which contacts the two extrusion pushers 806 and the pull-down bracket 809 respectively. It should be noted that, in this embodiment of the invention, when the cutting tool 5 deflects during processing, the retaining ring 808 deflects or vibrates, causing the extrusion pusher 806 or the pull-down bracket 809 to move downwards, and finally the extrusion pusher 806 causes the contact locking bracket 803 to move downwards, thereby also achieving the purpose of unlocking the sliding strip 801.

[0033] More specifically, in this embodiment of the invention, a return spring 810 is installed on the pull-down bracket 809, and the return spring 810 is installed on the inner wall of a pressing pusher 806; a pull-back spring 807 is installed on the pressing pusher 806, and the pull-back spring 807 is installed on the inner wall of the contact locking bracket 803. It should be noted that, in this embodiment of the invention, when the moving cutter holder 4 moves, it pushes the pressing pusher 806 to move, and the pressing pusher 806 slides within the contact locking bracket 803, causing the pull-back spring 807 to be stretched; when the moving cutter holder 4 moves, it pushes the pull-down bracket 809 to move within a pressing pusher 806, and causes the return spring 810 to be stretched. Therefore, under the contraction force of the pull-back spring 807 and the stretching force of the return spring 810, the two pressing pushers 806 and the pull-down bracket 809 remain in contact with the three moving cutter holders 4.

[0034] More specifically, in this embodiment of the invention, a sliding spring 802 is installed on the sliding strip 801, and the sliding spring 802 is installed on the inner wall of the fixture table 2; a buffer spring 804 is installed on the contact locking frame 803, and the buffer spring 804 is installed on the inner wall of the fixture table 2. It should be noted that, in this embodiment of the invention, during the processing of the valve 3, the valve 3 vibrates, causing the contact locking frame 803 to displace vertically with the vibration. The movement of the contact locking frame 803 causes the buffer spring 804 to be stressed, and then the buffer spring 804 buffers the contact locking frame 803 under the rebound force.

[0035] Please refer to the instruction manual attached. Figures 2-3 and Figures 12-13 Furthermore, the lathe for manufacturing valves that integrates chip isolation and anti-collision provided in this embodiment of the invention also includes an end sealing device 9, which is installed on the chip isolation device 7 and is used to seal the end of the valve 3. Specifically, the end sealing device 9 also includes two adapter mounting seats 901, which are respectively mounted on two positioning isolation frames 702. A sealing shaft 902 is rotatably mounted on the adapter mounting seat 901, and a sealing rotating plate 903 is mounted on one end of the sealing rotating shaft 902. It should be noted that, in this embodiment of the invention, when the sliding isolation frame 701 is combined with the positioning isolation frame 702, the sealing rotating plate 903 rotates, exposing the end face of the valve 3 for easy processing, thus realizing the automatic rotation of the sealing rotating plate 903.

[0036] More specifically, in this embodiment of the invention, a push lever 904 is installed on the closed rotating shaft 902, and a trigger pusher 905 is installed on the sliding isolation frame 701. The movement of the sliding isolation frame 701 drives the trigger pusher 905 to push the push lever 904 to rotate. In addition, a mounting groove 906 is provided on the adapter mounting base 901, and the closed rotating shaft 902 is rotatably installed in the mounting groove 906. A closed torsion spring 907 is installed on the inner wall of the mounting groove 906, and the closed torsion spring 907 is installed on the closed rotating shaft 902. It should be noted that, in this embodiment of the invention, when the sliding isolation frame 701 is combined with the positioning isolation frame 702, the sliding isolation frame 701 drives the trigger push frame 905 to push the push lever 904 to rotate. The push lever 904 drives the closed rotating plate 903 to rotate through the closed rotating shaft 902. At the same time, the closed rotating shaft 902 rotates in the mounting groove 906, and the closed torsion spring 907 is subjected to force. Therefore, under the rotational force of the closed torsion spring 907, it can help the closed rotating plate 903 to reset.

[0037] In summary, the working principle of the lathe for manufacturing valves that integrates chip isolation and collision prevention provided in this embodiment of the invention is as follows: When the three movable tool holders 4 drive the three cutting tools 5 to process the valve 3 on the fixture table 2, the movable tool holders 4 push the extrusion wedge block 715 to move, causing the extrusion wedge block 715 to drive the synchronous pull-down bracket 712 to move downward. The synchronous pull-down bracket 712 moves vertically within the limiting groove 716, causing the spreading spring 717 to contract under force. At the same time, the movement of the synchronous pull-down bracket 712 drives the push sliding shaft 714 to move within the push sliding hole 713, which in turn drives the transfer push plate 710 to move laterally. The transfer push plate 710 moves laterally. The drive linkage 711 pushes the rotating drive frame 705 to rotate. The rotation of the rotating drive frame 705 rotates within the return groove 708 via a linkage shaft 706, causing the return torsion spring 709 to be stressed. Simultaneously, the rotation of the rotating drive frame 705 drives the synchronous drive frame 704 to move via another linkage shaft 706. This causes the synchronous drive frame 704 to slide two sliding isolation frames 701, thereby allowing the sliding isolation frames 701 to engage with the positioning isolation frame 702, sealing the end face of the valve 3. It should be noted that when the two end faces of the valve 3 are sealed, three relatively enclosed spaces are formed, which isolates the debris generated during the processing of the three end faces of the valve 3, preventing mutual interference and thus ensuring the production quality of the valve 3. Furthermore, during the processing of valve 3, valve 3 vibrates, causing the contact locking frame 803 to displace vertically with the vibration. The movement of the contact locking frame 803 causes the buffer spring 804 to be stressed, and then the rebound force of the buffer spring 804 buffers the contact locking frame 803. However, when valve 3 vibrates excessively, the contact locking frame 803 moves excessively and disengages from the two sliding strips 801. Then, under the tension of the two sliding springs 802, the two sliding strips 801 drive the auxiliary fixture table 10 to slide out of the fixture table 2. It should be noted that if the cutting tool 5 vibrates excessively, or if the cutting tool 5 deflects during the machining process, the sleeve ring 808 will deflect or vibrate, causing the extrusion pusher 806 or the pull-down bracket 809 to move downwards. Ultimately, the extrusion pusher 806 will drive the contact locking bracket 803 to move downwards, thereby unlocking the sliding strip 801. This achieves the purpose of quickly disengaging the valve 3 from the cutting tool 5 in an emergency, thus avoiding affecting the machining quality of the valve 3. Furthermore, when the sliding isolation frame 701 is combined with the positioning isolation frame 702, the sliding isolation frame 701 drives the trigger push frame 905 to push the push lever 904 to rotate. The push lever 904 drives the sealing rotating plate 903 to rotate via the sealing rotating shaft 902. At the same time, the sealing rotating shaft 902 rotates within the mounting groove 906, causing the sealing torsion spring 907 to be stressed. It should be noted that when the sealing rotating plate 903 rotates, the end face of the valve 3 is exposed for easy processing; when the valve 3 is clamped, the sealing rotating plate 903 seals the end face of the valve 3 to prevent the valve 3 from being damaged by the cutting tool 5 during clamping, or to prevent the cutting tool 5 from injuring the worker.
