Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a cutting machine. Background Technology

[0002] Cutting primarily involves the technological process of cutting materials using cutting tools to shape them into desired forms. Cutting machine tools include vertical lathes and horizontal lathes, with vertical lathes typically used for cutting flat materials. Before machining a workpiece, it needs to be secured using a fixture. In existing technologies, this is generally achieved by bolt assemblies locking the fixture to the machine's worktable. Disassembly and assembly of the fixture requires specialized tools, making the process cumbersome, labor-intensive, and significantly reducing production efficiency. For example, a vertical metalworking machine is disclosed in Chinese patent application number 201610398799.3. Therefore, these shortcomings are significant, necessitating a solution. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a cutting machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cutting machine includes a base, a stand mounted on the base, a Y-axis moving drive mechanism mounted on the top surface of the base, an X-axis moving drive mechanism connected to the moving end of the Y-axis moving drive mechanism, a movable seat mounted on the moving end of the X-axis moving drive mechanism, a positioning mechanism detachably mounted on the movable seat, a fixture detachably connected to the positioning mechanism, and a cutting device mounted on the top of the stand and above the fixture. The positioning mechanism includes a positioning seat, a push-pull bracket, an elastic element, a gear, and a rotating locking block. The positioning seat is detachably connected to the movable seat. The positioning seat has a cavity inside, and 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, and the bottom surface of the rotating locking block is provided with... The device has a rotating shaft that is inserted into the center hole of the gear. The rotating shaft is rotatably mounted 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 slides through the guide hole and extends into the cavity. The two ends of the elastic element abut against the inner end of the push-pull frame and the front side wall of the cavity, respectively. The elastic element is used to apply a spring force to the push-pull frame to move into the cavity. The outer end of the push-pull frame is provided with a limit plate. The limit plate is located outside the front side of the positioning seat and is used to abut against the front side of the positioning seat. The side of the push-pull frame is provided with a rack. The rack meshes with the gear for transmission. The bottom surface of the clamp is recessed with an insertion groove for the rotating locking block to be inserted. The side wall of the insertion groove is recessed with a locking groove for the rotating locking block to be screwed into. The rotating locking block is screwed into the locking groove to lock the clamp onto the positioning seat.

[0006] Furthermore, there are two lock slots, two gears, and two rotating lock blocks. The two lock slots are matched with the two rotating lock blocks one by one, and the two gears are connected to the two rotating lock blocks one by one. Racks are provided on both sides of the push-pull frame, and the two gears mesh with the two racks for transmission.

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

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

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

[0010] Furthermore, a connecting plate is fixedly connected to the side 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 push spring, and a locking bolt. The side of the moving seat is recessed with a sliding hole that corresponds to and communicates with the locking hole. The bottom of the sliding hole is recessed with a threaded hole. The push spring is accommodated in the sliding hole. The axis of the locking block is provided with a countersunk hole. The stud of the locking bolt passes through the countersunk hole and the center hole of the push 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 push spring elastically abut against the bottom of the sliding hole and the inner end face of the locking block, respectively. The locking block can extend out of the sliding hole and be inserted into the locking hole.

[0011] Furthermore, the inner wall of the sliding hole is recessed with a limiting guide groove, and the side wall of the locking block is protruded with a guide block, which is slidably disposed in the limiting guide groove.

[0012] Furthermore, the top surface of the movable seat is provided with a first sliding groove and / or a first sliding block, and correspondingly, the bottom surface of the positioning seat is provided with a first sliding block and / or a first sliding groove, with the first sliding block slidingly engaging with the first sliding groove.

[0013] Furthermore, there are four connecting plates and four locking structures. The four connecting plates correspond one-to-one with the four locking structures, and the four connecting plates are located at both ends of the front and rear sides of the positioning seat.

[0014] Furthermore, the base of the X-axis moving drive mechanism is provided with a second slide groove and / or two sliders. Correspondingly, the bottom surface of the moving base is provided with a second slider and / or a second slide groove, and the second slider slides in cooperation with the second slide groove.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the positioning mechanism locks and fixes the fixture, the fixture clamps the workpiece, and the moving seat, along with the positioning mechanism, the fixture, and the workpiece, is driven to move under the coordinated cooperation of the X-axis moving drive mechanism and the Y-axis moving drive mechanism. The cutting tool of the cutting processing device processes the workpiece. Since the positioning mechanism and the fixture are detachably connected, the workpiece can be clamped on the fixture first, and then the fixture and workpiece can be installed on the positioning mechanism, which is beneficial for clamping the workpiece outside the machine and improves the efficiency of workpiece processing. Alternatively, the fixture can be installed on the positioning mechanism first, and then the workpiece can be clamped on the positioning mechanism. When the clamp is fixedly installed on the positioning mechanism, the rotating locking block is located in the locking groove. The rotating locking block and the locking groove cooperate to lock the clamp on the positioning mechanism. Because the elastic element continuously applies an inward elastic force to the push-pull frame, the limiting plate abuts against the front side of the positioning seat. Therefore, the rotating locking block can stably cooperate with the locking groove, which improves the stability of the positioning mechanism in fixing the clamp. When it is necessary to remove the clamp from the positioning mechanism, simply pull the push-pull frame outward, so that the push-pull frame moves outward along the guide hole and compresses the elastic element. The rack of the outward-moving push-pull frame drives the gear to rotate. The rotating gear drives the rotating locking block to rotate through the rotating shaft, so that the rotating locking block rotates out of the locking groove to the insertion groove. At this time, an upward force is applied to the clamp, which can separate the clamp from the positioning mechanism. After the clamp is removed, the pulling force on the push-pull frame is released. The push-pull frame will move into the cavity and reset under the action of the elastic element's rebound force, so that the limiting plate abuts against the front side of the positioning seat. When assembling the fixture and positioning mechanism, first pull the push-pull bracket outward to its limit position, then align the insertion slot of the fixture with the rotating locking block. Next, lower the fixture, and the moving seat supports the positioning seat, allowing the rotating locking block to insert into the insertion slot of the fixture. Then, release the pulling force on the push-pull bracket, causing it to move inward under the rebound force of the elastic element. The rack and pinion on the inward-moving push-pull bracket drives the gear to rotate, and the rotating gear drives the rotating locking block to rotate via the rotating shaft, causing the rotating locking block to rotate from the insertion slot to the locking slot until the push-pull bracket returns to its original position, and the limiting plate abuts against the front side of the positioning seat. At this point, the rotating locking block is fully rotated into the locking slot, thus locking the fixture by the positioning mechanism. This utility model allows for the assembly and disassembly of the fixture without the need for disassembly tools, making it convenient and efficient. Since different workpieces require different fixtures, simply setting a locking slot at the bottom of different fixtures allows for installation on the positioning mechanism. Therefore, different fixtures can be replaced according to different workpieces, resulting in good versatility and strong practicality. In addition, the positioning mechanism is detachably connected to the moving base, which facilitates the disassembly, assembly, and maintenance of the positioning mechanism.

[0023] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0024] like Figures 1 to 5As shown, the present invention provides a vertical cutting machine, which includes a base 1, a stand 2 mounted on the base 1, a Y-axis moving drive mechanism 3 mounted on the top surface of the base 1, an X-axis moving drive mechanism 4 connected to the moving end of the Y-axis moving drive mechanism 3, a moving seat 5 mounted on the moving end of the X-axis moving drive mechanism 4, a positioning mechanism 6 detachably mounted on the moving seat 5, a clamp 7 detachably connected to the positioning mechanism 6, and a fixture mounted on the top of the stand 2 and located above the clamp 7. The cutting processing device 8 and the positioning mechanism 6 include a positioning seat 9, a push-pull bracket 10, an elastic element 11, a gear 12, and a rotating locking block 13. The positioning seat 9 is detachably connected to the movable seat 5. The positioning seat 9 has a cavity 14 inside. The front side of the positioning seat 9 has a guide hole 15 communicating with the cavity 14. The gear 12 is rotatably connected to the bottom wall of the cavity 14. The bottom surface of the rotating locking block 13 is provided with a rotating shaft 16, which is inserted into the center hole of the gear 12. The rotating shaft 16 is rotatably positioned on the positioning seat 5. The positioning seat 9 has a rotating locking block 13 rotatably mounted above the top surface of the positioning seat 9. A gap exists between the bottom surface of the rotating locking block 13 and the top surface of the positioning seat 9. The push-pull bracket 10 slides through the guide hole 15 and extends into the cavity 14. The two ends of the elastic member 11 abut against the inner end of the push-pull bracket 10 and the front side wall of the cavity 14, respectively. The elastic member 11 applies a spring force to the push-pull bracket 10 as it moves into the cavity 14. A limiting plate 17 is provided at the outer end of the push-pull bracket 10, located outside the front side of the positioning seat 9. For contact with the front side of the positioning seat 9, the push-pull bracket 10 is provided with a rack 18 on its side, which meshes with the gear 12 for transmission. The bottom surface of the clamp 7 is recessed with an insertion groove 19 for inserting the rotating locking block 13. The side wall of the insertion groove 19 is recessed with a locking groove 20 for the rotating locking block 13 to be screwed into. 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 clamp 7 onto the positioning seat 9. The elastic element 11 is horizontally arranged and located in the cavity 14. Specifically, the elastic element 11 can be a spring. The cutting and processing device 8 is an existing device and will not be described in detail here.

[0025] In practical applications, the positioning mechanism 6 locks and fixes the fixture 7, which clamps the workpiece. Under the coordinated action of the X-axis moving drive mechanism 4 and the Y-axis moving drive mechanism 3, the moving seat 5, along with the positioning mechanism 6, the fixture 7, and the workpiece, moves. The cutting tool of the cutting processing device 8 processes the workpiece. Since the positioning mechanism 6 and the fixture 7 are detachably connected, the workpiece can be clamped on the fixture 7 first, and then the fixture 7 along with the workpiece can be installed on the positioning mechanism 6, which is beneficial for clamping the workpiece outside the machine and improves the efficiency of workpiece processing. Alternatively, the fixture 7 can be installed on the positioning mechanism 6 first, and then the workpiece can be clamped on the positioning mechanism 6. When the clamp 7 is fixedly installed on the positioning mechanism 6, the rotating locking block 13 is located in the locking groove 20. The rotating locking block 13 cooperates with the locking groove 20 to lock the clamp 7 on the positioning mechanism 6. Since the elastic element 11 continuously applies an inward elastic force to the push-pull bracket 10, and the limiting plate 17 abuts against the front side of the positioning seat 9, the rotating locking block 13 can stably cooperate with the locking groove 20, improving the stability of the positioning mechanism 6 in fixing the clamp 7. When it is necessary to remove the clamp 7 from the positioning mechanism 6, simply pull the push-pull bracket 10 outward so that the push-pull bracket 10 moves along the guide hole 15. The outward movement and compression of the elastic element 11 causes the rack 18 of the outward-moving push-pull bracket 10 to drive the gear 12 to rotate. The rotating gear 12 drives the rotating locking block 13 to rotate via the rotating shaft 16, causing the rotating locking block 13 to rotate out of the locking groove 20 to the insertion groove 19. At this time, an upward force is applied to the clamp 7, which can separate the clamp 7 from the positioning mechanism 6. After disassembling the clamp 7, the pulling force on the push-pull bracket 10 is released. The push-pull bracket 10 will move into the cavity 14 and reset under the action of the elastic force of the elastic element 11, so that the limiting plate 17 abuts against the front side of the positioning seat 9. When it is necessary to assemble the clamp 7 and the positioning mechanism 6, first pull the push-pull bracket 10 outward to the limit position, then align the insertion slot 19 of the clamp 7 with the rotating locking block 13, then put the clamp 7 down, and the moving seat 5 supports the positioning seat 9 so that the rotating locking block 13 is inserted into the insertion slot 19 of the clamp 7. Then release the pulling force on the push-pull bracket 10, so that the push-pull bracket 10 moves inward under the action of the elastic force of the elastic element 11. The rack 18 on the inwardly moving push-pull bracket 10 drives the gear 12 to rotate. The rotating gear 12 drives the rotating locking block 13 to rotate via the rotating shaft 16, so that the rotating locking block 13 rotates from the insertion slot 19 to the locking groove 20 until the push-pull bracket 10 returns to its original position and the limiting plate 17 abuts against the front side of the positioning seat 9. At this time, the rotating locking block 13 is completely rotated into the locking groove 20 to realize the locking of the clamp 7 by the positioning mechanism 6. This invention enables the assembly and disassembly of the clamp 7 without the need for disassembly tools, making the process convenient and efficient. Since different workpieces require different clamps 7, they can be installed on the positioning mechanism 6 simply by providing locking grooves 20 at the bottom of each clamp 7. Therefore, different clamps 7 can be replaced according to different workpieces, demonstrating good versatility and practicality. Furthermore, the positioning mechanism 6 is detachably connected to the movable base 5, facilitating the assembly, disassembly, 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 locking block 13 is screwed into the locking groove 20 to lock the clamp 7, the brake brakes the gear 12, which improves the stability of the gear 12, thereby improving the stability of the rotating locking block 13 locking the clamp 7 and further improving the safety of use. When it is necessary to rotate the locking block 13, the brake will release the gear 12, so that the rack 18 can drive the gear 12 to rotate.

[0027] Specifically, the support frame 2 is equipped with a cutting fluid supply mechanism, which supplies cutting fluid to the workpiece and the cutting tool of the cutting device 8.

[0028] In this embodiment, there are two locking slots 20, two gears 12, and two rotating locking blocks 13. Each locking slot 20 corresponds to one rotating locking block 13, and each gear 12 is connected to one rotating locking block 13. Racks 18 are provided on both sides of the push-pull frame 10, and each gear 12 meshes with one rack 18 for transmission. This structural design ensures uniform force distribution on the push-pull frame 10, improving the stability of its reciprocating movement. Furthermore, the two rotating locking blocks 13 securely lock the clamp 7 onto the positioning mechanism 6, ensuring a stable clamping action.

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

[0030] In this embodiment, a handle 21 is provided on the outer side of the limiting plate 17; the handle 21 is provided to facilitate 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 of the positioning seat 9 via a shaft 22. A torsion spring 35 is sleeved on the shaft 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 elastic force to the protective handle 23 so that the protective handle 23 abuts against the front side of the limiting 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 initial state or the clamp 7 is locked onto the positioning mechanism 6, the protective handle 23, under the elastic force of the torsion spring 35, always abuts against the front side of the limiting plate 17 and the top surface of the handle 21. The handle 21 blocks and supports the protective handle 23, and the protective handle 23 blocks and limits the limiting plate 17 to prevent the push-pull frame 10 from moving outward. This further improves the stability of the push-pull frame 10, prevents the push-pull frame 10 from loosening and thus prevents the clamp 7 from being unable to be securely locked, and plays a safety protection role, reducing the probability of safety accidents. When it is necessary to pull the push-pull frame 10 outward, first flip the protective handle 23 upward, so that the protective handle 23 releases its obstruction of the limiting plate 17, and then the push-pull frame 10 can be pulled.

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

[0034] In this embodiment, a connecting plate 25 is fixedly connected to the side of the positioning seat 9. The bottom end of the connecting plate 25 extends downward 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. The side of the moving seat 5 is recessed with a sliding hole 30 for corresponding communication with the locking hole 26. The bottom of the sliding hole 30 is recessed with a threaded hole 31. The pushing spring 28 is accommodated in the sliding hole 30. The axis of the locking block 27 is provided with a countersunk hole 32. The stud of the locking bolt 29 passes through the countersunk hole 32 and the center 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 countersunk hole 32. The locking block 27 is slidably connected to the sliding hole 30. The two ends of the pushing spring 28 elastically abut against the bottom of the sliding hole 30 and the inner end face 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 onto the movable seat 5, the locking block 27 is inserted into the locking hole 26 of the connecting plate 25. When it is necessary to disassemble the positioning seat 9, a tool is inserted into the countersunk hole 32 to align with the locking bolt 29 and screw the locking bolt 29 so that the locking bolt 29 is screwed into the threaded hole 31. 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 locking on the connecting plate 25, thereby unlocking the positioning seat 9. At this time, the positioning seat 9 can be removed from the movable seat 5. When the positioning seat 9 needs to be installed on the movable seat 5, the positioning seat 9 and the movable seat 5 move relative to each other until the locking hole 26 of the connecting plate 25 on the positioning seat 9 corresponds and communicates with the sliding hole 30 of the movable seat 5. The 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, a limiting guide groove 33 is recessed on the inner sidewall of the sliding hole 30, and a guide block 34 is protruding from the sidewall of the locking block 27. The guide block 34 is slidably disposed within the limiting guide groove 33. Specifically, the locking block 27 is cylindrical, and the sliding hole 30 is a circular hole. During 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 slides in cooperation with the limiting guide groove 33 to improve the stability of the movement of the locking block 27. Moreover, 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 disengaging from the sliding hole 30.

[0037] In this embodiment, the top surface of the movable seat 5 is provided with a first sliding groove and / or a first sliding block. Correspondingly, the bottom surface of the positioning seat 9 is provided with a first sliding block and / or a first sliding groove, and the first sliding block slides into the first sliding groove. When the positioning seat 9 and the movable seat 5 are assembled or disassembled, the first sliding block of the movable seat 5 slides into the first sliding groove of the positioning seat 9, and the first sliding groove of the movable seat 5 slides into the first sliding block of the positioning seat 9, thereby improving the stability of the assembly or disassembly of the positioning seat 9 and the movable seat 5 and making the assembly or disassembly more convenient.

[0038] In this embodiment, there are four connecting plates 25 and four locking structures 24. Each of the four connecting plates 25 corresponds to one of the four locking structures 24, and the four connecting plates 25 are located at both ends of the front and rear sides of the positioning seat 9. This structural design ensures that the positioning seat 9 is subjected to uniform force, improving the stability of locking the positioning seat 9. Furthermore, when assembling the positioning seat 9 with the movable seat 5, the four connecting plates 25 form a guide rail and align with the movable seat 5, allowing the positioning seat 9 to be laterally inserted into the movable seat 5. The guide rail acts as a guide, improving the stability of the assembly of the positioning seat 9 and the movable seat 5.

[0039] In this embodiment, the base of the X-axis moving drive 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 slides into the second sliding groove. During the process of the X-axis moving drive mechanism 4 driving the moving seat 5 to move, the second sliding block of the base of the X-axis moving drive mechanism 4 slides into the second sliding groove of the moving seat 5, and the second sliding groove of the base of the X-axis moving drive mechanism 4 slides into the second sliding block of the moving seat 5, thereby improving the stability of the movement of the moving seat 5.

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

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
