Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and in particular to a cutting processing device. Background Art

[0002] Cutting mainly performs technological cutting on materials, using tools to process materials to form the required shapes. Cutting machine tools include vertical lathes and horizontal lathes. When cutting flat materials, vertical lathes are usually used for processing. Before a cutting processing device processes a workpiece, the workpiece needs to be fixed by a fixture. In the prior art, the fixture is generally locked to the workbench of the cutting processing device through a bolt assembly. When the fixture needs to be disassembled and assembled, disassembly and assembly tools are required to achieve the disassembly and assembly of the fixture, making the disassembly, assembly, and replacement of the fixture troublesome, with a large labor intensity, and greatly reducing the production efficiency. For example, a vertical metal processing machine disclosed in a Chinese patent document with the application number 201610398799.3. Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a cutting processing device.

The positioning mechanism includes a positioning seat, a push-pull frame, an elastic member, a gear, and a rotating locking block. The positioning seat is detachably connected to the moving seat. A cavity is provided inside the positioning seat. A guide hole communicating with the cavity is opened on the front side of the positioning seat. The gear is rotatably connected to the bottom wall of the cavity. A rotating shaft is provided on the bottom surface of the rotating locking block. The rotating shaft is inserted into the central hole of the gear. The rotating shaft is rotatably arranged on the positioning seat. There is a gap between the bottom surface of the rotating locking block and the top surface of the positioning seat. The push-pull frame slidably penetrates through the guide hole and extends into the cavity. The two ends of the elastic member respectively abut against the inner end of the push-pull frame and the front side wall of the cavity. The elastic member is used to apply an elastic force to the push-pull frame to move it into the cavity. A limiting plate is provided at the outer end of the push-pull frame. The limiting plate is located outside the front side of the positioning seat and is used to abut against the front side of the positioning seat. A rack is provided on the side of the push-pull frame.

Rack teeth are provided on both sides of the push-pull frame, and the two gears are respectively in meshing transmission with the two rack teeth.

[0007] Furthermore, a handle protrudes from the outer side surface of the limiting plate.

[0008] Furthermore, a protective handle is rotatably connected to the front side surface of the positioning seat via a shaft rod. A torsion spring is sleeved outside the shaft rod, and the two free ends of the torsion spring are respectively connected to the protective handle and the positioning seat. The torsion spring is used to apply an elastic force to the protective handle so that the protective handle abuts against the front side surface of the limiting plate and the top surface of the handle.

[0009] Furthermore, the moving seat is detachably connected to the positioning seat via a locking structure.

[0010] Furthermore, a connecting plate is fixedly connected to the side surface of the positioning seat. The bottom end of the connecting plate extends downward and is provided with a locking hole. The locking structure includes a locking block, a pushing spring, and a locking bolt. A sliding hole corresponding to and communicating with the locking hole is recessed on the side surface of the moving seat. A threaded hole is recessed at the bottom of the sliding hole. The pushing spring is accommodated in the sliding hole. A countersunk hole is provided on the axis of the locking block. The stud of the locking bolt passes through the countersunk hole and the central hole of the pushing spring and is threadedly connected to the threaded hole. The nut of the locking bolt is accommodated in the countersunk hole. The locking block is slidably connected to the sliding hole. The two ends of the pushing spring are respectively elastically abutted against the bottom of the sliding hole and the inner end surface of the locking block. The locking block can extend out of the sliding hole and be inserted into the locking hole.

[0011] Furthermore, a limiting guide groove is recessed on the inner side wall of the sliding hole, and a guide block protrudes from the side wall of the locking block. The guide block is slidably arranged in the limiting guide groove.

[0012] Furthermore, a first sliding groove or / and a first sliding block is / are provided on the top surface of the moving seat. Correspondingly, a first sliding block or / and a first sliding groove is / are provided on the bottom surface of the positioning seat. The first sliding block and the first sliding groove are in sliding fit.

[0013] Furthermore, the number of connecting plates and the number of locking structures are both four. The four connecting plates are respectively in one-to-one correspondence and cooperation with the four locking structures. The four connecting plates are respectively located at the two ends of the front and rear side surfaces of the positioning seat.

[0014] Furthermore, a second sliding groove or / and a second sliding block is / are provided on the seat body of the X-axis moving driving mechanism. Correspondingly, a second sliding block or / and a second sliding groove is / are provided on the bottom surface of the moving seat. The second sliding block and the second sliding groove are in sliding fit.

[0015] Advantages of the present invention: In practical applications, the positioning mechanism locks and positions the fixture, and the fixture clamps the workpiece. Under the coordinated cooperation of the X-axis movement driving mechanism and the Y-axis movement driving mechanism, the moving seat drives the positioning mechanism, the fixture and the workpiece to move, and the cutting tool of the cutting processing device processes the workpiece. Since the positioning mechanism is detachably connected to the fixture, the workpiece can be first clamped on the fixture and then the fixture together with the workpiece can be installed on the positioning mechanism, which is beneficial to clamping the workpiece outside the machine and improves the processing efficiency of the workpiece. Or the fixture can be first installed on the positioning mechanism and then the workpiece can be clamped on the positioning mechanism. When the fixture is fixedly installed on the positioning mechanism, the rotating lock block is located in the lock groove, and the rotating lock block cooperates with the lock groove to lock the fixture on the positioning mechanism. Since the elastic member continuously applies an inward elastic force to the push-pull frame and the limiting plate abuts against the front side surface of the positioning seat, the rotating lock block can stably cooperate with the lock groove, improving the stability of the positioning mechanism for fixing the fixture. When it is necessary to disassemble the fixture from the positioning mechanism, only need to pull the push-pull frame outwards, so that the push-pull frame moves outwards along the guide hole and compresses the elastic member. The rack of the outwardly moving push-pull frame drives the gear to rotate, and the rotating gear drives the rotating lock block to rotate via the rotating shaft, so that the rotating lock block rotates out of the lock groove to the insertion groove. At this time, applying an upward force to the fixture can separate the fixture from the positioning mechanism. After disassembling the fixture, cancel the pulling force on the push-pull frame, and the push-pull frame will move into the cavity and reset under the restoring force of the elastic member, so that the limiting plate abuts against the front side surface of the positioning seat. When it is necessary to assemble the fixture and the positioning mechanism, first pull the push-pull frame outwards to the extreme position, then align the insertion groove of the fixture with the rotating lock block, then put down the fixture, and the moving seat supports the positioning seat, so that the rotating lock block is inserted into the insertion groove of the fixture. Then release the pulling force on the push-pull frame, so that the push-pull frame moves inwards under the restoring force of the elastic member. The rack on the inwardly moving push-pull frame drives the gear to rotate, and the rotating gear drives the rotating lock block to rotate via the rotating shaft, so that the rotating lock block rotates from the insertion groove into the lock groove until the push-pull frame returns to its original position and the limiting plate abuts against the front side surface of the positioning seat. At this time, the rotating lock block completely rotates into the lock groove to realize the locking of the positioning mechanism to the fixture. The present invention can realize the disassembly and assembly of the fixture without using disassembly and assembly tools, and the disassembly and assembly are convenient and efficient. Since different fixtures are required for different workpieces, only need to set a lock groove at the bottom of different fixtures to be installed on the positioning mechanism for use, so different fixtures can be replaced according to different workpieces, with good versatility and strong practicability. In addition, the positioning mechanism is detachably connected to the moving seat, which is convenient for the disassembly, assembly and maintenance of the positioning mechanism.

[0023] For the convenience of those skilled in the art to understand, the present invention will be further described below in conjunction with the embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present invention.

[0024] As Figures 1 to 5As shown in the figure, a vertical cutting machining device provided by the present invention includes a base 1, a vertical frame 2 installed on the base 1, a Y-axis movement driving mechanism 3 installed on the top surface of the base 1, an X-axis movement driving mechanism 4 connected to the moving end of the Y-axis movement driving mechanism 3, a moving seat 5 installed on the moving end of the X-axis movement driving mechanism 4, a positioning mechanism 6 detachably installed on the moving seat 5, a fixture 7 detachably connected to the positioning mechanism 6, and a cutting machining device 8 installed on the top of the vertical frame 2 and located above the fixture 7. The positioning mechanism 6 includes a positioning seat 9, a push-pull frame 10, an elastic member 11, a gear 12, and a rotating locking block 13. The positioning seat 9 is detachably connected to the moving seat 5. An accommodation cavity 14 is provided inside the positioning seat 9. A guide hole 15 communicating with the accommodation cavity 14 is opened on the front side surface of the positioning seat 9. The gear 12 is rotatably connected to the bottom wall of the accommodation cavity 14. A rotating shaft 16 is provided on the bottom surface of the rotating locking block 13. The rotating shaft 16 is inserted into the central hole of the gear 12. The rotating shaft 16 is rotatably arranged in the positioning seat 9. The rotating locking block 13 is rotatably arranged above the top surface of the positioning seat 9. There is a gap between the bottom surface of the rotating locking block 13 and the top surface of the positioning seat 9. The push-pull frame 10 slides through the guide hole 15 and extends into the accommodation cavity 14. The two ends of the elastic member 11 respectively abut against the inner end of the push-pull frame 10 and the front side wall of the accommodation cavity 14. The elastic member 11 is used to apply an elastic force to the push-pull frame 10 to move it into the accommodation cavity 14. A limiting plate 17 is provided at the outer end of the push-pull frame 10. The limiting plate 17 is located outside the front side surface of the positioning seat 9 and is used to abut against the front side surface of the positioning seat 9. A rack 18 is provided on the side surface of the push-pull frame 10. The rack 18 meshes with the gear 12 for transmission. An insertion groove 19 for inserting the rotating locking block 13 is concavely provided on the bottom surface of the fixture 7. A locking groove 20 for screwing the rotating locking block 13 into is concavely provided on the side wall of the insertion groove 19. The locking groove 20 and the insertion groove 19 form an inverted L-shaped groove. The rotating locking block 13 is screwed into the locking groove 20 to lock the fixture 7 on the positioning seat 9. The elastic member 11 is horizontally arranged and located inside the accommodation cavity 14. Specifically, the elastic member 11 can adopt a spring. The cutting machining device 8 is an existing device and will not be elaborated here.

[0025] In practical applications, the positioning mechanism 6 locks and positions the fixture 7. The fixture 7 clamps the workpiece. Under the coordinated cooperation of the X-axis moving drive mechanism 4 and the Y-axis moving drive mechanism 3, the moving seat 5 is driven to move together with the positioning mechanism 6, the fixture 7 and the workpiece, and the cutting tool of the cutting processing device 8 processes the workpiece. Since the positioning mechanism 6 is detachably connected to the fixture 7, the workpiece can be first clamped on the fixture 7 and then the fixture 7 together with the workpiece can be installed on the positioning mechanism 6, which is beneficial to realize the clamping of the workpiece outside the machine and improve the processing efficiency of the workpiece. It is also possible to first install the fixture 7 on the positioning mechanism 6 and then clamp the workpiece on the positioning mechanism 6. When the fixture 7 is fixedly installed on the positioning mechanism 6, the rotating lock block 13 is located in the lock groove 20, and the rotating lock block 13 cooperates with the lock groove 20 to lock the fixture 7 on the positioning mechanism 6. Since the elastic member 11 continuously applies an inward elastic force to the push-pull frame 10 and the limiting plate 17 abuts against the front side surface of the positioning seat 9, the rotating lock block 13 can stably cooperate with the lock groove 20, improving the stability of the positioning mechanism 6 for fixing the fixture 7. When it is necessary to disassemble the fixture 7 from the positioning mechanism 6, only need to pull the push-pull frame 10 outwards, so that the push-pull frame 10 moves outwards along the guide hole 15 and compresses the elastic member 11. The rack 18 of the outwards moving push-pull frame 10 drives the gear 12 to rotate. The rotating gear 12 drives the rotating lock block 13 to rotate via the rotating shaft 16, so that the rotating lock block 13 rotates out of the lock groove 20 to the insertion groove 19. At this time, applying an upward force to the fixture 7 can separate the fixture 7 from the positioning mechanism 6. After disassembling the fixture 7, cancel the pulling force on the push-pull frame 10, and the push-pull frame 10 will move into the cavity 14 and reset under the action of the resilience of the elastic member 11, so that the limiting plate 17 abuts against the front side surface of the positioning seat 9. When it is necessary to assemble the fixture 7 and the positioning mechanism 6, first pull the push-pull frame 10 outwards to the extreme position, then align the insertion groove 19 of the fixture 7 with the rotating lock block 13, then put down the fixture 7, and the moving seat 5 supports the positioning seat 9, so that the rotating lock block 13 is inserted into the insertion groove 19 of the fixture 7. Then release the pulling force on the push-pull frame 10, so that the push-pull frame 10 moves inwards under the action of the resilience of the elastic member 11. The rack 18 on the inwards moving push-pull frame 10 drives the gear 12 to rotate. The rotating gear 12 drives the rotating lock block 13 to rotate via the rotating shaft 16, so that the rotating lock block 13 rotates from the insertion groove 19 into the lock groove 20 until the push-pull frame 10 returns to its original position and the limiting plate 17 abuts against the front side surface of the positioning seat 9. At this time, the rotating lock block 13 is completely rotated into the lock groove 20 to realize the locking of the positioning mechanism 6 to the fixture 7. The present invention can realize the disassembly and assembly of the fixture 7 without using disassembly and assembly tools, and the disassembly and assembly are convenient and efficient. And because the fixtures 7 required for different workpieces are different, only need to set the lock groove 20 at the bottom of different fixtures 7 to be installed on the positioning mechanism 6 for use. Therefore, different fixtures 7 can be replaced according to different workpieces, with good versatility and strong practicability. In addition, the positioning mechanism 6 is detachably connected to the moving seat 5, which is convenient for the disassembly, assembly and maintenance of the positioning mechanism 6.

[0026] Specifically, a brake is provided in the cavity 14 for braking the gear 12. When the rotating lock block 13 is screwed into the lock groove 20 to lock the fixture 7, the brake brakes the gear 12, improving the stability of the gear 12, thereby improving the stability of the rotating lock block 13 locking the fixture 7 and further improving the use safety. When the rotating lock block 13 needs to be rotated, the brake will release the gear 12, enabling the rack 18 to drive the gear 12 to rotate.

[0027] Specifically, the vertical frame 2 is equipped with a cutting fluid supply mechanism for supplying cutting fluid to the workpiece and the cutting tool of the cutting processing device 8.

[0028] In this embodiment, the number of lock grooves 20, the number of gears 12, and the number of rotating lock blocks 13 are all two. The two lock grooves 20 are respectively in one-to-one correspondence and cooperation with the two rotating lock blocks 13. The two gears 12 are respectively connected to the two rotating lock blocks 13 in one-to-one correspondence. Rack bars 18 are provided on both sides of the push-pull frame 10, and the two gears 12 are respectively meshed with the two rack bars 18 for transmission. This structural design makes the force on the push-pull frame 10 uniform, improves the stability of driving the push-pull frame 10 to reciprocate, and the two rotating lock blocks 13 lock the fixture 7 on the positioning mechanism 6, capable of firmly locking the fixture 7.

[0029] Specifically, the rotating lock block 13 is fan-shaped, and the shapes of the insertion groove 19 and the lock groove 20 are both semi-circular. The push-pull frame 10 is a rectangular frame, and the elastic member 11 is located inside the rectangular frame, making the structure of the push-pull frame 10 and the elastic member 11 compact, and the inner wall of the push-pull frame 10 abuts against the elastic member 11, improving the working stability of the elastic member 11.

[0030] In this embodiment, a handle 21 protrudes from the outer side surface of the limit plate 17. The setting of the handle 21 facilitates the operator to drive the push-pull frame 10 to move.

[0031] In this embodiment, a protective handle 23 is rotatably connected to the front side surface of the positioning seat 9 via a shaft rod 22. A torsion spring 35 is sleeved outside the shaft rod 22, and the two free ends of the torsion spring 35 are respectively connected to the protective handle 23 and the positioning seat 9. The torsion spring 35 is used to apply an elastic force to the protective handle 23 so that the protective handle 23 abuts against the front side surface of the limit plate 17 and the top surface of the handle 21. Specifically, the protective handle 23 is L-shaped.

[0032] When the push-pull frame 10 is in the starting state or the fixture 7 is locked on the positioning mechanism 6, the protection handle 23 is always in contact with the front side of the limit plate 17 and the top surface of the handle 21 under the elastic force of the torsion spring 35. The handle 21 blocks and supports the protection handle 23, and the protection handle 23 blocks and limits the limit plate 17 to prevent the push-pull frame 10 from moving outwards, further improving the stability of the push-pull frame 10 and preventing the push-pull frame 10 from loosening and resulting in the inability to firmly lock the fixture 7, playing a role in safety protection and reducing the probability of safety accidents. When it is necessary to pull the push-pull frame 10 outwards, first turn the protection handle 23 upwards to release the block on the limit plate 17, and then the push-pull frame 10 can be pulled.

[0033] In this embodiment, the moving seat 5 is detachably connected to the positioning seat 9 via the locking structure 24. This structural design facilitates the disassembly and assembly of the moving seat 5 and the positioning seat 9.

[0034] In this embodiment, a connecting plate 25 is fixedly connected to the side surface of the positioning seat 9. The bottom end of the connecting plate 25 extends downwards and is provided with a locking hole 26. The locking structure 24 includes a locking block 27, a pushing spring 28 and a locking bolt 29. A sliding hole 30 corresponding to and communicating with the locking hole 26 is recessed on the side surface of the moving seat 5. A threaded hole 31 is recessed at the bottom of the sliding hole 30. The pushing spring 28 is accommodated in the sliding hole 30. A counterbore 32 is provided on the axis of the locking block 27. The stud of the locking bolt 29 passes through the counterbore 32 and the central hole of the pushing spring 28 and is threadedly connected to the threaded hole 31. The nut of the locking bolt 29 is accommodated in the counterbore 32. The locking block 27 is slidably connected to the sliding hole 30. The two ends of the pushing spring 28 are elastically abutted against the bottom of the sliding hole 30 and the inner end surface of the locking block 27 respectively. The locking block 27 can extend out of the sliding hole 30 and be inserted into the locking hole 26.

[0035] When the locking structure 24 locks the positioning seat 9 on the moving seat 5, the locking block 27 is inserted into the locking hole 26 of the connecting plate 25; when the positioning seat 9 needs to be removed, a tool is inserted into the countersunk hole 32, aligned with the locking bolt 29 and screwed, so that the locking bolt 29 is screwed into the threaded hole 31, and the locking bolt 29 drives the locking block 27 to move into the sliding hole 30 and compresses the push spring 28 until the locking block 27 moves out of the locking hole 26, so that the locking block 27 releases the lock on the connecting plate 25, thereby unlocking the positioning seat 9, and the positioning seat 9 can be removed from the moving seat 5 at this time. When it is necessary to install the positioning seat 9 on the moving seat 5, the positioning seat 9 and the moving seat 5 are moved relative to each other until the locking hole 26 of the connecting plate 25 on the positioning seat 9 corresponds to and communicates with the sliding hole 30 of the moving seat 5. A tool is inserted into the countersunk hole 32 to align the locking bolt 29 and screw the locking bolt 29 so that the locking bolt 29 is screwed out of the threaded hole 31. As the locking bolt 29 moves outward, the elastic force of the push spring 28 pushes the locking block 27 to move outward along the sliding hole 30 until the locking block 27 is inserted into the locking hole 26 of the connecting plate 25.

[0036] In this embodiment, the inner side wall of the sliding hole 30 is concavely provided with a limiting guide groove 33, and the side wall of the locking block 27 is convexly provided with a guide block 34, and the guide block 34 is slidably arranged in the limiting guide groove 33; specifically, the locking block 27 is cylindrical, and the sliding hole 30 is a round hole. In the process of the locking bolt 29 and the push spring 28 cooperating to drive the locking block 27 to move along the sliding hole 30, the guide block 34 slidably cooperates with the limiting guide groove 33 to improve the stability of the movement of the locking block 27, and the inner wall of the limiting guide groove 33 can block the guide block 34, which not only prevents the locking block 27 from rotating relative to the sliding hole 30, but also prevents the locking block 27 from escaping from the sliding hole 30.

[0037] In this embodiment, the top surface of the moving seat 5 is provided with a first slide groove or / and a first slider, and correspondingly, the bottom surface of the positioning seat 9 is provided with a first slider or / and a first slide groove, and the first slider slides in cooperation with the first slide groove. When the positioning seat 9 and the moving seat 5 are disassembled and assembled, the first slider of the moving seat 5 slides in cooperation with the first slide groove of the positioning seat 9, and the first slide groove of the moving seat 5 slides in cooperation with the first slider of the positioning seat 9, so as to improve the disassembly and assembly stability of the positioning seat 9 and the moving seat 5, and make the disassembly and assembly more convenient.

[0038] In this embodiment, the number of the connecting plates 25 and the number of the locking structures 24 are both four, and the four connecting plates 25 are respectively matched with the four locking structures 24 in a one-to-one manner, and the four connecting plates 25 are respectively located at both ends of the front and rear sides of the positioning seat 9. This structural design makes the positioning seat 9 evenly stressed, and improves the firmness of the locking positioning seat 9. In addition, when the positioning seat 9 is assembled with the moving seat 5, the four connecting plates 25 form a guide rail and align with the moving seat 5, and the positioning seat 9 is laterally inserted on the moving seat 5. The guide rail plays a guiding role, which improves the stability of the assembly of the positioning seat 9 and the moving seat 5.

[0039] In this embodiment, the base of the X-axis movement driving mechanism 4 is provided with a second sliding groove and / or two sliding blocks. Correspondingly, the bottom surface of the moving seat 5 is provided with a second sliding block and / or a second sliding groove, and the second sliding block is in sliding fit with the second sliding groove. During the process of the X-axis movement driving mechanism 4 driving the moving seat 5 to move, the second sliding block on the base of the X-axis movement driving mechanism 4 is in sliding fit with the second sliding groove of the moving seat 5, and the second sliding groove on the base of the X-axis movement driving mechanism 4 is in sliding fit with the second sliding block of the moving seat 5, so as to improve the stability of the movement of the moving seat 5.

[0040] All the technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
