Description

Technical Field

[0001] This utility model relates to the field of five-axis CNC rotary table technology, specifically a direct-drive motor five-axis CNC rotary table. Background Technology

[0002] A five-axis CNC rotary table is an accessory for CNC machine tools that allows a workpiece to rotate and tilt around five different axes during machining. These five axes typically include three linear axes (X, Y, Z) and two rotary axes (A, B, or C). Five-axis rotary tables enable efficient and precise machining of complex-shaped parts, such as aero-engine blades and automotive molds. A direct-drive motor five-axis rotary table refers to a five-axis rotary table that uses direct-drive technology. Unlike traditional gear-driven transmissions, direct-drive motors directly transmit the motor's torque to the worktable, reducing intermediate transmission links and thus improving accuracy and response speed. This design typically offers higher positioning accuracy, less backlash, and better dynamic performance.

[0003] Based on the above, the inventors have discovered the following problems: current fixing clamps are usually three-jaw chucks, which are not easy to disassemble and cannot securely clamp and fix some specially shaped materials, making them inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a direct-drive motor five-axis CNC rotary table in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a direct-drive motor five-axis CNC rotary table to solve the problems mentioned in the background art.

[0006] A five-axis CNC rotary table with direct drive motor includes a CNC assembly. The CNC assembly includes an A-axis rotary mechanism, and a B-axis rotary mechanism is provided at the output end of the A-axis rotary mechanism. The rotary table assembly is provided at the output end of the B-axis rotary mechanism. Both the A-axis and B-axis rotary mechanisms are driven by a direct drive motor. A fixing component is provided on the top of the rotary table assembly. The rotary table assembly includes a fixed platform. A positioning groove is formed on the top of the fixed platform. The fixing component includes a fixed plate. A positioning block is provided at the bottom of the fixed plate. The positioning block engages with the positioning groove. A fixing groove is formed on the top of the fixed plate. Screw holes are formed at both ends of the fixing groove. Fixing screws are threaded into the screw holes.

[0007] By adopting the above technical solution, the A-axis rotation mechanism facilitates the control of the B-axis rotation mechanism around the X-axis, and the B-axis rotation mechanism facilitates the control of the turntable assembly around the Y-axis. Since both the A-axis and B-axis rotation mechanisms are driven by direct-drive motors, high-precision, high-response rotation control is easily achieved, precisely controlling the material's rotation along the A and B axes. The turntable assembly facilitates the fixation of the fixed components, allowing the CNC assembly to control their rotation. The engagement of the positioning block and positioning slot ensures the fixed components are precisely and stably fixed on the top of the turntable assembly, enabling the fixed components to drive the material's precise rotation. The fixed components can be easily installed and disassembled, facilitating replacement according to the material's type. The fixing slot facilitates the positioning and fixing of special-type materials, ensuring precise and stable material fixation and rotation. The fixing screws securely fix the material inside the fixing slot.

[0008] Furthermore, a slot for inserting a block is provided on one side of the positioning groove, and a fixed inserting block is slidably connected inside the slot for inserting a block.

[0009] By adopting the above technical solution, the setting of the insertion slot facilitates the lateral sliding of the fixed insertion block along the insertion slot.

[0010] Furthermore, a fixing slot is provided on the side of the positioning block, and the fixing slot is located on the outer side of one end of the fixing block.

[0011] By adopting the above technical solution, the fixing slot is set on the outside of one end of the fixing block, which makes it easy for the fixing block to fix the positioning block inside the positioning groove, thereby realizing the stable fixing of the fixing component to the top of the turntable component.

[0012] Furthermore, the fixed plug is provided with limiting blocks at both the top and bottom, and a handle block is fixedly installed at the end of the fixed plug away from the positioning groove.

[0013] By adopting the above technical solution, the handle block is designed to facilitate the removal of the fixing block from the fixing slot when replacing the fixing component.

[0014] Furthermore, the top and bottom of the insertion block slot are provided with limiting grooves, which are slidably connected to the limiting block.

[0015] By adopting the above technical solution, the sliding connection between the limiting groove and the limiting block facilitates the limiting of the sliding of the fixed plug and prevents the fixed plug from being pulled out of the plug slot.

[0016] Furthermore, a pin groove is provided on one side of the end of the insertion block groove, and a locking pin is slidably connected inside the pin groove.

[0017] By adopting the above technical solution and setting the locking pin, it is easy to use the locking pin to fix the position of the fixing block and prevent the fixing block from loosening during use.

[0018] Furthermore, a locking hole is provided on one side of the fixing block, and one end of the locking pin is inserted into the locking hole.

[0019] By adopting the above technical solution, the locking hole facilitates the fixing of the fixed block with the locking pin.

[0020] Furthermore, magnets are fixedly installed inside the locking hole and at the end of the locking pin.

[0021] By adopting the above technical solution, the magnets facilitate the installation of the fixing components. When the fixing block is inserted into the appropriate position, the two magnets attract each other, inserting the locking pin into the locking hole to fix the fixing block and preventing the locking pin from slipping out of the locking hole during use.

[0022] Furthermore, a pull-out handle is fixedly installed at the end of the locking pin away from the fixed insert, and a limit groove is formed on the surface of the locking pin.

[0023] By adopting the above technical solution and by designing a pull-out handle, the locking pin can be easily pulled out when disassembling and replacing the fixing components.

[0024] Furthermore, a limiting ring is fixedly installed at one end of the pin groove, and the limiting ring is slidably connected to the limiting groove.

[0025] By adopting the above technical solution, the setting of the limiting ring facilitates the limiting of the sliding of the locking pin, thus preventing the locking pin from being pulled out of the pin groove.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: The A-axis rotation mechanism facilitates control of the B-axis rotation mechanism around the X-axis; the B-axis rotation mechanism facilitates control of the turntable assembly around the Y-axis; both the A-axis and B-axis rotation mechanisms are driven by direct-drive motors, facilitating high-precision, high-response rotation control and precise control of material rotation along the A and B axes; the turntable assembly facilitates the fixing of the fixed component, allowing the CNC assembly to control its rotation; the positioning block engages with the positioning slot, ensuring precise and stable installation of the fixed component on the top of the turntable assembly, enabling the fixed component to drive the material to rotate precisely; and the fixed component can be easily installed and disassembled, facilitating replacement according to the material type.

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.

[0034] Please see Figures 1-5 This utility model provides a technical solution: a direct-drive motor five-axis CNC rotary table, including a CNC component 1. The CNC component 1 includes an A-axis rotation mechanism 11, which facilitates the control of a B-axis rotation mechanism 12 to rotate around the X-axis. The output end of the A-axis rotation mechanism 11 is provided with a B-axis rotation mechanism 12, which facilitates the control of a rotary table component 2 to rotate around the Y-axis. The output end of the B-axis rotation mechanism 12 is also provided with a rotary table component 2. Both the A-axis rotation mechanism 11 and the B-axis rotation mechanism 12 are driven by direct-drive motors, which facilitates high-precision, high-response rotation control, allowing precise control of material rotation along the A-axis and B-axis. A fixing component 3 is provided on the top of the rotary table component 2, which facilitates the fixing of the fixing component 3, allowing the CNC component 1 to control the rotation of the fixing component 3. The turntable assembly 2 includes a fixed platform 21 with a positioning groove 22 on its top. The fixed assembly 3 includes a fixed plate 31 with a positioning block 33 at its bottom. The positioning block 33 engages with the positioning groove 22, which facilitates the precise and stable installation of the fixed assembly 3 on the top of the turntable assembly 2. This allows the fixed assembly 3 to drive the material to rotate precisely and easily, and also facilitates the installation and removal of the fixed assembly 3. It also allows for easy replacement of the fixed assembly 3 according to the material type. The fixed plate 31 has a fixing groove 32 on its top, which facilitates the positioning and fixing of special types of materials, allowing the device to accurately and stably fix and rotate the material. The fixing groove 32 has screw holes 35 at both ends, with fixing screws 36 threaded inside. The fixing screws 36 facilitate the secure installation of the material inside the fixing groove 32.

[0035] The positioning groove 22 has an insertion slot 23 on one side, and a fixed insertion block 24 is slidably connected inside the insertion slot 23. The insertion slot 23 facilitates the accommodating the fixed insertion block 24 to slide laterally along the insertion slot 23.

[0036] The positioning block 33 has a fixing slot 34 on its side. The fixing slot 34 is located on the outer side of one end of the fixing block 24. By setting the fixing slot 34 on the outer side of one end of the fixing block 24, it is easy for the fixing block 24 to fix the positioning block 33 inside the positioning groove 22, thereby realizing the stable fixing of the fixing component 3 to the top of the turntable component 2.

[0037] The fixed insert 24 is provided with limit blocks 26 at the top and bottom. A handle block 27 is fixedly installed at the end of the fixed insert 24 away from the positioning groove 22. The handle block 27 makes it easy to pull the fixed insert 24 out of the fixed slot 34 when replacing the fixed component 3.

[0038] The top and bottom of the insertion slot 23 are provided with limiting grooves 25, which are slidably connected to the limiting block 26. The slidable connection between the limiting groove 25 and the limiting block 26 facilitates the limiting of the sliding of the fixed insertion block 24 and prevents the fixed insertion block 24 from being pulled out of the insertion slot 23.

[0039] The insertion slot 23 has a pin groove 29 on one side of its end. A locking pin 211 is slidably connected inside the pin groove 29. The locking pin 211 is used to fix the position of the insertion block 24 and prevent the insertion block 24 from becoming loose during use.

[0040] The fixed plug 24 has a locking hole 28 on one side, and one end of the locking pin 211 is inserted into the locking hole 28. The locking hole 28 facilitates the fixing of the fixed plug 24 with the locking pin 211.

[0041] Magnets are fixedly installed inside the locking hole 28 and at the end of the locking pin 211. The magnets facilitate mutual attraction between the two magnets when the fixing block 24 is inserted into the appropriate position during the installation of the fixing component 3, so that the locking pin 211 is inserted into the locking hole 28 to fix the fixing block 24 and prevent the locking pin 211 from sliding out of the locking hole 28 during use.

[0042] Among them, the locking pin 211 is fixedly installed with a pull-out handle 213 at the end away from the fixed plug 24, and a limit groove 212 is opened on the surface of the locking pin 211. The setting of the pull-out handle 213 makes it easy to pull out the locking pin 211 when disassembling and replacing the fixed component 3.

[0043] One end of the pin groove 29 is fixedly installed with a limiting ring 210, which is slidably connected to the limiting groove 212. The limiting ring 210 is set to limit the sliding of the locking pin 211 and prevent the locking pin 211 from being pulled out of the pin groove 29.

[0044] Specifically, the working principle of this direct-drive motor five-axis CNC rotary table is as follows: During use, the positioning block 33 engages with the positioning slot 22, facilitating the precise and stable installation of the fixing component 3 on the top of the rotary table assembly 2. This allows the fixing component 3 to drive the material to rotate precisely, and also facilitates easy installation and removal of the fixing component 3. It also allows for easy replacement of the fixing component 3 according to the material type. The fixing slot 32 facilitates the positioning and fixing of special-type materials, ensuring precise and stable material fixation and rotation. The fixing screw 36 securely fixes the material inside the fixing slot 32. The insertion slot 23 allows the fixing insertion block 24 to slide laterally along the insertion slot 23. The fixing slot 34, located on the outer side of one end of the fixing insertion block 24, allows the fixing insertion block 24 to fix the positioning block 33 inside the positioning slot 22, thus securing the fixing component 3 firmly to the top of the rotary table assembly 2. The locking pin 211 facilitates the use of the locking pin to secure the fixing insertion block. The position of block 24 is fixed to prevent it from loosening during use. The locking hole 28 facilitates the locking pin 211 in securing block 24. The magnets attract each other when block 24 is inserted into the appropriate position during installation of the fixing assembly 3, inserting the locking pin 211 into the locking hole 28 to secure block 24 and prevent it from slipping out during use. The pull handle 213... The locking pin 211 can be easily pulled out when disassembling and replacing the fixing component 3. The setting of the limiting ring 210 can limit the sliding of the locking pin 211 and prevent the locking pin 211 from being pulled out of the pin groove 29. The setting of the handle block 27 can facilitate the pulling out of the fixing block 24 from the fixing slot 34 when replacing the fixing component 3. The limiting slide groove 25 is slidably connected to the limiting block 26 to limit the sliding of the fixing block 24 and prevent the fixing block 24 from being pulled out of the block groove 23.
