Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a stable CNC machine tool fixture that is easy to disassemble. Background Technology

[0002] The field of machining technology encompasses a wide range of processes and technologies, focusing on the mechanical processing of raw materials to manufacture parts or finished products with specific shapes, sizes, and properties. This field integrates multiple disciplines such as design, materials science, manufacturing processes, and automation control, achieving precise transformation from raw materials to final products. Common machining processes include turning, milling, grinding, drilling, stamping, and casting, each with its unique application scenarios and advantages.

[0003] CNC machine tool fixtures refer to the various jigs, cutting tools, and auxiliary devices used for fixing, clamping, positioning, supporting, and cutting workpieces when machining on a CNC lathe. They are an important part of CNC lathe machining, and their quality and performance directly affect machining quality and production efficiency.

[0004] Traditional machine tool fixtures often use bolts and nuts for installation, which is cumbersome. Changing fixtures may require different installation tools, causing some trouble for the workers. In addition, traditional fixtures are relatively fixed in position during use, which may create blind spots during workpiece processing. Therefore, a stable CNC machine tool fixture that is easy to disassemble is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in replacing fixtures and the relatively fixed fixture design, and to propose a stable CNC machine tool fixture that is easy to disassemble.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stable CNC machine tool fixture that is easy to disassemble includes a support frame, a bearing plate, and a fixture. A bearing platform is movably connected to the top of the support frame, and a machining tool is movably connected to the side of the bearing platform near the flipping fixing frame. The support frame and the bearing plate are slidably connected. A flipping fixing frame is symmetrically fixedly connected to the bearing plate. A fixture disk is rotatably mounted on the flipping fixing frame. A flipping locking assembly is jointly provided on the fixture disk and the flipping fixing frame. The flipping locking assembly includes a flipping motor and gear mounted on the flipping fixing frame, multiple hydraulic cylinders and a limit plate fixedly mounted on the fixture disk, a limit bolt movably connected to the limit plate, and a limit block fixedly connected to the fixture. The flipping locking assembly drives the gear to rotate the fixture disk along the center line of the gear through the rotation of the flipping motor. The extension and retraction of the hydraulic cylinders causes the limit plate to fit and lock with the fixture. The limit bolt pushes the locking plate and the limit block to lock together through rotation.

[0008] The above technical solution further includes:

[0009] An X-axis motor is fixedly connected to the side of the support frame near the flipping fixing frame. An X-axis threaded rod is fixedly connected to the output end of the X-axis motor. The X-axis threaded rod is threadedly connected to the bearing plate and rotatably connected to the support frame. X-axis slide rods are symmetrically fixedly connected to the inner side of the support frame. The two X-axis slide rods are slidably connected to the flipping fixing frame. The X-axis motor rotates to drive the X-axis threaded rods, and the X-axis threaded rods drive the bearing plate to move along the two X-axis slide rods.

[0010] A Y-axis motor is fixedly connected to the top outer side of the support frame. A Y-axis threaded rod is fixedly connected to the output end of the Y-axis motor. The Y-axis threaded rod is rotatably connected to the support frame and threadedly connected to the support platform. Y-axis sliding rods are symmetrically fixedly connected to the top inner side of the support frame. The two Y-axis sliding rods are slidably connected to the support platform. The Y-axis motor drives the Y-axis threaded rod to rotate, and the Y-axis threaded rod drives the support platform to move along the two Y-axis sliding rods. The support platform is used to support the tool holder.

[0011] A Z-axis motor is fixedly connected to the side of the support platform away from the machining tool. A Z-axis threaded rod is fixedly connected to the output end of the Z-axis motor. The Z-axis threaded rod is threadedly connected to the tool holder and rotatably connected to the support platform. Z-axis slide rods are symmetrically fixedly connected to the inner side of the support platform. The two Z-axis slide rods are slidably connected to the tool holder. The tool holder is fixedly connected to the machining tool. The machining tool is used for workpiece machining. The rotation of the Z-axis motor drives the Z-axis threaded rod to rotate. The Z-axis threaded rod drives the tool holder, which is threaded to it, to move along the guide of the two Z-axis slide rods.

[0012] The flipping motor is fixedly connected to the flipping fixed frame. A worm gear is fixedly connected to the output end of the flipping motor. The worm gear meshes with a gear. The flipping motor drives the worm gear to rotate, and the worm gear drives the gear to rotate.

[0013] A drive shaft is fixedly connected to the inner side of the gear. The drive shaft is rotatably connected to the flipping fixing frame and fixedly connected to the clamping disk. The gear drives the drive shaft to rotate, and the rotation of the drive shaft drives the clamping disk to rotate.

[0014] Multiple hydraulic cylinders are fixedly connected to the clamping plate, and the hydraulic cylinders are fixedly connected to the limiting plate. The telescopic ends of the multiple hydraulic cylinders are in contact with the clamp. The hydraulic cylinders are used to clamp the clamp, and the limiting plate is used to limit the clamp.

[0015] The number of the limiting blocks is multiple sets, and all sets of the limiting blocks are fixedly connected to the clamp. The limiting bolts are threadedly connected to the limiting plates, the clamping plates are rotatably connected to the limiting plates, and the clamping plates are in contact with the limiting blocks. The clamping plates and the limiting blocks cooperate with each other to fix the clamp to the inside of the clamping plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the rotation of the flipping motor in the flipping locking assembly drives the fixture to rotate during the processing, which allows the workpiece to be processed from multiple angles, thereby meeting more complex processing requirements. By rotating the fixture, the operator can more easily approach the difficult-to-process areas of the workpiece, improving the comprehensiveness and accuracy of the processing.

[0018] 2. In this utility model, the design of the flip-locking component makes the disassembly process of the clamp simple and quick. By controlling the contraction of the hydraulic cylinder and the rotation of the limit bolt, the clamp and clamp plate can be fixed. Furthermore, through the hydraulic action of the hydraulic cylinder and the limiting action of the limit block and the clamping plate, the fixing effect of the clamp is better, and the disassembly time is greatly shortened, thus improving the overall work efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figures 1-5 As shown, this utility model proposes a stable CNC machine tool fixture that is easy to disassemble, including a support frame 1, a bearing plate 2, and a fixture 22. A bearing platform 12 is movably connected to the top of the support frame 1. A machining tool 3 is movably connected to the side of the bearing platform 12 near the flipping fixing frame 8. The support frame 1 and the bearing plate 2 are slidably connected. A flipping fixing frame 8 is symmetrically fixedly connected to the bearing plate 2. A fixture disk 21 is rotatably mounted on the flipping fixing frame 8. A flipping locking assembly is jointly provided on the fixture disk 21 and the flipping fixing frame 8. The flipping locking assembly includes a flipping mechanism. The rotating fixed frame 8 is equipped with a rotating motor 17 and gear 19, multiple hydraulic cylinders 23 and a limiting plate 24 fixedly installed on the clamping plate 21, a limiting bolt 25 movably connected to the limiting plate 24, and a limiting block 5 fixedly connected to the clamp 22. The rotating locking assembly drives the gear 19 to rotate the clamping plate 21 along the center line of the gear 19 through the rotation of the rotating motor 17. The extension and retraction of the hydraulic cylinder 23 causes the limiting plate 24 to fit and clamp the clamp 22. The limiting bolt 25 pushes the clamping plate 26 to clamp the limiting block 5 through rotation.

[0028] An X-axis motor 4 is fixedly connected to the side of the support frame 1 near the flipping fixed frame 8. An X-axis threaded rod 7 is fixedly connected to the output end of the X-axis motor 4. The X-axis threaded rod 7 is threadedly connected to the bearing plate 2. The X-axis threaded rod 7 is rotatably connected to the support frame 1. X-axis slide rods 6 are symmetrically fixedly connected to the inner side of the support frame 1. The two X-axis slide rods 6 are slidably connected to the flipping fixed frame 8. The X-axis motor 4 rotates to drive the X-axis threaded rod 7. The X-axis threaded rod 7 drives the bearing plate 2 to move along the two X-axis slide rods 6.

[0029] A Y-axis motor 9 is fixedly connected to the top outer side of the support frame 1. A Y-axis threaded rod 11 is fixedly connected to the output end of the Y-axis motor 9. The Y-axis threaded rod 11 is rotatably connected to the support frame 1. The Y-axis threaded rod 11 is threadedly connected to the support platform 12. Y-axis slide rods 10 are symmetrically fixedly connected to the top inner side of the support frame 1. The two Y-axis slide rods 10 are slidably connected to the support platform 12. The Y-axis motor 9 drives the Y-axis threaded rod 11 to rotate. The Y-axis threaded rod 11 drives the support platform 12 to move along the two Y-axis slide rods 10. The support platform 12 is used to support the tool holder 16.

[0030] A Z-axis motor 13 is fixedly connected to the side of the support platform 12 away from the machining tool 3. A Z-axis threaded rod 15 is fixedly connected to the output end of the Z-axis motor 13. The Z-axis threaded rod 15 is threadedly connected to the tool holder 16. The Z-axis threaded rod 15 is rotatably connected to the support platform 12. Z-axis slide rods 14 are symmetrically fixedly connected to the inner side of the support platform 12. The two Z-axis slide rods 14 are slidably connected to the tool holder 16. The tool holder 16 is fixedly connected to the machining tool 3. The machining tool 3 is used for workpiece machining. The rotation of the Z-axis motor 13 drives the Z-axis threaded rod 15 to rotate. The Z-axis threaded rod 15 is used to drive the tool holder 16, which is threadedly connected to it, to move along the guide of the two Z-axis slide rods 14.

[0031] In this embodiment, during workpiece processing, the rotation of the X-axis motor 4 drives the rotation of the X-axis threaded rod 7. The rotation of the X-axis threaded rod 7 causes the support plate 2, which is threaded to it, to reciprocate under the guidance of the two X-axis slide rods 6. At the same time, by controlling the rotation of the Y-axis motor 9, the rotation of the Y-axis motor 9 drives the rotation of the Y-axis threaded rod 11. The rotation of the Y-axis threaded rod 11 causes the support platform 12, which is threaded to it, to reciprocate under the guidance of the two Y-axis slide rods 10. As the support platform 12 moves, it drives the tool holder 16, which is movably connected to it, to move. The movement of the tool holder 16 causes the movement of the processing tool 3, thus realizing the movement of the processing tool 3 in the Y direction.

[0032] Simultaneously, the rotation of the Z-axis motor 13 is controlled, which drives the rotation of the Z-axis threaded rod 15. The rotation of the Z-axis threaded rod 15 drives the tool holder 16, which is threaded to it, to move up and down under the guidance of the two Z-axis slide rods 14. This enables the tool holder 16 to move in the Z-axis direction. The movement of the tool holder 16 drives the movement of the machining tool 3. Then, the tool holder 16 is moved to a suitable position. By rotating the flip motor 17, the rotation of the flip motor 17 drives the rotation of the worm gear 18. The rotation of the worm gear 18 drives the rotation of the gear 19 that meshes with it. The rotation of the gear 19 drives the rotation of the fixture 22. The machining tool 3 is used to process the workpiece held by the two fixtures 22. At the same time, the worm gear 18 drives the gear 19, which can play a self-locking role.

[0033] Example 2

[0034] like Figures 1-5 As shown, based on Embodiment 1, the flip motor 17 is fixedly connected to the flip fixing frame 8, and the output end of the flip motor 17 is fixedly connected to the worm gear 18. The worm gear 18 meshes with the gear 19. The flip motor 17 drives the worm gear 18 to rotate, and the worm gear 18 drives the gear 19 to rotate.

[0035] A drive shaft 20 is fixedly connected to the inner side of the gear 19. The drive shaft 20 is rotatably connected to the flipping fixing frame 8. The drive shaft 20 is fixedly connected to the clamping disk 21. The gear 19 drives the drive shaft 20 to rotate, and the rotation of the drive shaft 20 drives the clamping disk 21 to rotate.

[0036] Multiple hydraulic cylinders 23 are fixedly connected to the clamping plate 21, and the hydraulic cylinders 23 are fixedly connected to the limiting plate 24. The telescopic ends of the multiple hydraulic cylinders 23 are in contact with the clamp 22. The hydraulic cylinders 23 are used to clamp the clamp 22, and the limiting plate 24 is used to limit the clamp 22.

[0037] There are multiple sets of limit blocks 5, and all sets of limit blocks 5 are fixedly connected to the clamp 22. The limit bolt 25 is threadedly connected to the limit plate 24. The clamping plate 26 is rotatably connected to the limit plate 24. The clamping plate 26 and the limit block 5 are in contact with each other. The clamping plate 26 and the limit block 5 cooperate with each other, so that the clamp 22 is fixed on the inner side of the clamping plate 21.

[0038] In this embodiment, during the process of changing the clamp, the retraction of multiple hydraulic cylinders 23 is controlled, causing the extension and retraction ends of the hydraulic cylinders 23 to disengage from the clamp 22. By rotating the limiting bolt 25, the limiting bolt 25 moves away from the limiting plate 24 due to the threaded connection between the limiting bolt 25 and the limiting plate 24. The movement of the limiting bolt 25 causes the clamping plate 26, which is rotatably connected to it, to disengage from the limiting block 5. Subsequently, the extension and retraction ends of the hydraulic cylinders 23 move, causing the limiting plate 24 to move. This completes the disassembly of the clamp 22. During installation, the above operation can be reversed.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
