Description

Technical Field

[0001] This invention relates to the field of CNC machine tool mechanical structure technology, specifically a five-axis linkage machine tool worktable tilting and locking mechanism. Background Technology

[0002] The mechanical structure of a CNC machine tool mainly refers to the combination of mechanical components that realize various movements and functions of the machine tool. During milling, in order for the cutting tool to accurately cut different parts of the blade, the worktable needs to be rotated to different angles. For example, when machining the curved surfaces of the blade's base and back, rotating the worktable allows the cutting tool to cut at the optimal angle, ensuring the machining accuracy and surface quality of the curved surface. In this case, the worktable rotation locking mechanism can firmly lock the worktable after it has been rotated to a predetermined angle, preventing the worktable from shaking or shifting during machining, which would affect machining accuracy.

[0003] The five-axis linkage machine tool worktable mainly includes a worktable body made of high-strength materials with good rigidity and stability, a positioning device for accurately determining the position of the blade blank, a clamping device for firmly fixing the blade blank, a flipping mechanism that can realize multi-angle processing, a drive system that drives the linear or flipping motion of the worktable, and a measurement and feedback device that can provide real-time feedback on the worktable position and ensure processing accuracy.

[0004] In the existing technology, some milling machine tool table tilting and locking mechanisms are subjected to high temperatures for a long time. The material properties of the locking mechanism will gradually decline, such as reduced hardness and weakened strength. This makes the mechanism more susceptible to deformation, cracks, or even breakage when subjected to various forces during table tilting and machining, thus shortening the service life of the mechanism. For example, high temperature reduces the wear resistance of key components of the locking mechanism, such as gears and shafts, accelerating their wear process. Therefore, a five-axis linkage machine tool table tilting and locking mechanism is proposed. Summary of the Invention

[0016] This invention provides a five-axis linkage machine tool table tilting and locking mechanism. It has the following advantages:

[0017] 1. Water in the tank flows to the nozzle through the distributor pipe under the action of the water pump. The nozzle sprays water onto the workpiece and milling cutter on the worktable to cool them down. At the same time, the fan can accelerate the airflow, which realizes the cooling of the flip-locking mechanism, avoids the thermal expansion of the tool and the thermal expansion and contraction of the workpiece due to heat transfer, keeps the relative position between the tool and the workpiece stable, helps to reduce the surface roughness of the blades and improve the machining accuracy.

[0018] 2. When water flows in the inlet pipe, it drives the rotating blades on the rotating rod to rotate. The rotating blades drive gear one to rotate, and gear one meshes with gear two, causing the rotating shaft to rotate. The disc and limit rod on the rotating shaft rotate accordingly. The limit rod drives the moving rod to move up and down in the water tank through the sleeve and connecting rod, shaking the filter plate one, thus preventing the filter screen from clogging. This effectively filters out impurities such as iron filings and grinding particles mixed in the water, making it convenient to clean the filter screen.

[0019] 3. The lubricating oil in the oil tank flows into the square housing. When the sliding box moves on the guide rail, the trapezoidal slider slides inside the square housing. Under the action of the second spring, the lubricating oil flows through the through hole to the guide rail, realizing quantitative lubrication of the guide rail, reducing the number of times the guide rail needs to be repaired and replaced, thereby saving a lot of maintenance costs and the cost of replacement parts.

[0031] refer to Figure 2 and Figure 3The flip drive assembly 2 includes a servo motor 21, which is the core component providing the flip power. By precisely controlling the output speed and direction, it provides the power source for the entire flipping motion. Its high-precision control ensures accurate flipping angle of the worktable 7.

The installation error between shafts ensures the reliability and stability of power transmission. The top of the expansion coupling 23 is rotatably connected to the rotating shaft 24. The harmonic reducer 22 reduces and increases the torque of the power output by the servo motor 21, improving the output torque so that the rotating shaft 24 can drive the gear disk 32 to rotate more smoothly and powerfully, ensuring the stability of the flipping action. The rotating shaft 24 transmits the power from the expansion coupling 23 to the gear disk 32, causing the gear disk 32 to rotate on the lower plate body 31, thereby realizing the flipping of the worktable 7. The indexing plate assembly 3 includes the lower plate body 31, the bottom of the lower plate body 31... The lower plate 31 is fixedly connected to the top of the machine tool base 1. A gear plate 32 is rotatably connected to the top of the lower plate 31. An upper plate 33 is rotatably connected to the outside of the gear plate 32. The upper plate 33 rotates with the gear plate 32, causing the worktable 7 to flip, thus connecting the gear plate 32 and the worktable 7. The locking actuator 4 includes multiple hydraulic cylinders 41. The adjacent sides of the multiple hydraulic cylinders 41 are fixedly connected inside the gear plate 32. The multiple hydraulic cylinders 41 are installed inside the gear plate 32 and serve as a power source. After receiving a control signal, they drive the clamping jaws 42 to clamp or release the workpiece. The driving of the hydraulic cylinders 41... The end is fixedly connected to a clamping claw 42. The inside of the toothed disc 32 is provided with multiple T-slots 43. The T-slots 43 provide guidance for the movement of the clamping claw 42, ensuring that the clamping claw 42 can accurately move to the designated position for clamping operation.

[0032] Specifically, the flip drive component 2, the indexing plate component 3, and the locking execution component 4 work together to achieve precise flipping, positioning, and reliable locking of the worktable 7 during the workpiece milling process.

[0033] refer to Figure 1 and Figure 4The operating component 6 includes an electric push rod 61. The electric push rod 61 drives the sliding box 62 to move on the guide rail 63 via telescopic movement, thereby achieving coarse horizontal adjustment of the processing position above the worktable 7 and adjusting the position of the processing area. The bottom of the electric push rod 61 is fixedly connected to the top of the fixed block 5. The driving end of the electric push rod 61 is fixedly connected to the sliding box 62. The top of the fixed block 5 is fixedly connected to the guide rail 63, which provides guidance for the movement of the sliding box 62, ensuring the straightness and stability of the movement of the sliding box 62 and ensuring the accuracy of the processing position adjustment. Support columns 64 are fixedly connected to the top left and right sides of the sliding box 62. A drive motor 65 is fixedly connected to the right side of the right support column 64. The driving end of the drive motor 65 is connected to a lead screw 66. By rotating the lead screw 66, the precise horizontal position of the moving frame 67 is achieved. The adjustment meets the requirements of the machining for horizontal position accuracy. The drive end of the drive motor 65 is fixedly connected to the lead screw 66. The external thread of the lead screw 66 is connected to the moving frame 67. The lead screw 66 rotates under the drive of the drive motor 65 and is threadedly connected to the moving frame 67, converting the rotational motion of the motor into the linear motion of the moving frame 67, thereby realizing the horizontal position adjustment of the moving frame 67. The top of the moving frame 67 is fixedly connected to the drive motor 68. The drive end of the drive motor 68 is fixedly connected to the lead screw 69. The lead screw 69 converts the rotational motion of the motor into the vertical linear motion of the milling cutter 610, thereby realizing the vertical position adjustment of the milling cutter 610. The bottom of the moving frame 67 is provided with the milling cutter 610. The external sliding connection of the two guide rails 63 is on the left and right sides inside the sliding box 62.

[0034] Specifically, the operating component 6 enables precise positioning and flexible adjustment of the milling cutter 610 in three-dimensional space during the workpiece milling process, thereby ensuring efficient and high-precision milling operations.

[0035] refer to Figure 6 and Figure 7The cooling assembly 8 includes a fixed plate 81, the rear side of which is fixedly connected to the front side of the machine tool base 1. A fan 82 is fixedly connected to the top right side of the fixed plate 81. When the fan 82 is working, it accelerates airflow and assists the water flowing out of the water tank 83 in cooling the workpiece and the milling cutter 610, thereby improving the cooling effect. A water tank 83 is fixedly connected to the top of the fixed plate 81. A filter plate 84 is slidably connected to the inner wall of the water tank 83. The filter plate 84 filters the water in the water tank 83 to prevent impurities from entering the diversion pipe 86, ensuring that the water sprayed from the nozzle 87 is clean and avoiding clogging of the nozzle and affecting processing. A diversion pipe 86 is fixedly connected to the right side of the filter plate 84. 6 connects water pump 85 and nozzle 87, guiding the water pumped by water pump 85 to nozzle 87 to achieve water diversion and ensure that water is sprayed evenly to the processing area.

A filter plate 2 89 is fixedly connected inside the workbench 7. The filter plate 2 89 performs secondary filtration on the cooling water flowing down the guide groove 88 to further remove impurities and ensure that the water flowing back to the water tank 83 is clean. Water inlet pipes 810 are fixedly connected to the left and right sides inside the workbench 7. Fixed boxes 811 are fixedly connected to the outside of the two water inlet pipes 810.

[0036] Specifically, the cooling component 8 achieves efficient cooling and water recycling during the workpiece milling process. The fixed plate 81 supports all components, the fan 82 accelerates airflow to assist in cooling, the water tank 83 stores and pre-filters water through the first filter plate 84, and the water pump 85 directs water to the nozzle 87 through the diversion pipe 86 to cool the processing area. The guide channel 88, the second filter plate 89, and the water inlet pipe 810 in the worktable 7 work together to recover the cooled water to the fixed box 811, where it is recycled after secondary filtration, ensuring processing accuracy and stable equipment operation.

[0037] refer to Figure 7 and Figure 8The anti-clogging component 9 includes a rotating rod 91, with rotating blades 92 fixedly connected to the outside of the rotating rod 91. The rotating blades 92 are driven to rotate by the water flow, providing power to subsequent components. Gears 93 are fixedly connected to the left and right sides of the rotating blades 92. The rotating blades 92 rotate under the impact of the water flow from the inlet pipe 810, driving the gears 93 to rotate and converting the kinetic energy of the water flow into mechanical energy. A water storage tank 94 is provided inside the fixed box 811. Inside the housing 811, rotating shafts 95 are rotatably connected to both the left and right sides. Gear 2 96 is fixedly connected to the outside of rotating shafts 95. Gear 2 96 meshes with gear 1 93, receiving power transmitted from gear 1 93 and driving rotating shafts 95 to rotate, thus realizing power transmission and motion conversion. Disk 97 is fixedly connected to the opposite sides of both rotating shafts 95. Limiting rods 98 are fixedly connected to the opposite sides of both rotating shafts 95. Sleeves 99 are sleeved around the limiting rods 98, and connecting rods 9 are fixedly connected to the outside of sleeves 99. 10. A movable rod 911 is rotatably connected to the bottom of the connecting rod 910. Square limiting plates 912 are fixedly connected to the four corners inside the water tank 83. A spring 913 is fixedly connected to the top of the square limiting plate 912. The spring 913 acts as a buffer and reset when the movable rod 911 shakes the filter plate 84, ensuring that the filter plate 84 can work continuously and effectively. The tops of multiple springs 913 are fixedly connected to the bottom of the filter plate 84. The outer surfaces of multiple rotating blades 92 are slidably connected to the inside of the water storage tank 94. The outer side of gear 93 is meshed with the outer side of gear 96. The outer side of two moving rods 911 is slidably connected to the left and right sides inside the fixed box 811. The limiting rod 98 makes an eccentric movement under the drive of the disc 97. The moving rod 911 moves up and down through the sleeve 99 and the connecting rod 910 to shake the filter plate 84. The outer side of two moving rods 911 is slidably connected to the left and right sides inside the water tank 83. The outer side of two water inlet pipes 810 is fixedly connected to the left and right sides inside the machine tool base 1.

[0038] Specifically, the automatic anti-clogging function of filter plate 84 in cooling component 8 is realized, ensuring smooth circulation of cooling water. The water flow from the inlet pipe 810 impacts the rotating blade 92, driving the rotating rod 91 to rotate, converting the kinetic energy of the water into mechanical energy. Through the meshing of gear 1 93 and gear 2 96, the rotating shaft 95 is driven to rotate, which in turn causes the disc 97 to drive the limiting rod 98 to make eccentric movements. Through the sleeve 99 and the connecting rod 910, the moving rod 911 is driven to slide up and down in the water tank 83, periodically shaking the filter plate 84 to prevent impurities from accumulating and clogging. The spring 913 buffers the shaking and helps the filter plate 84 to reset, ensuring that the filter plate 84 continues to work effectively and maintaining the stable operation of the cooling system.

[0039] refer to Figure 4 and Figure 5The lubrication assembly 10 includes two oil reservoirs 101. A square housing 102 is fixedly connected to the bottom of each oil reservoir 101. A trapezoidal slider 103 is slidably connected inside the square housing 102. A spring 104 is fixedly connected to the top of the trapezoidal slider 103. The oil reservoirs 101 store lubricating oil, providing an oil source for lubrication and ensuring sufficient lubricating oil to lubricate the contact area between the guide rail 63 and the sliding box 62. Through holes 105 are provided on both the left and right sides of the interior of the square housing 102. These through holes 105 are channels for the lubricating oil to flow out. The lubricating oil flows from the trapezoidal slider 103 to the guide rail 63, thus lubricating the contact area between the guide rail 63 and the sliding box 62. The guide rail 63 has multiple square grooves 106 inside. The bottom of the square grooves 106 is slidably connected to the top of the guide rail 63. The top of the spring 104 is fixedly connected to the top inner wall of the square housing 102. After the trapezoidal slider 103 squeezes the lubricating oil, the spring 104 provides a restoring force to return the trapezoidal slider 103 to its initial position, ensuring a continuous supply of lubricating oil. The outside of the square housing 102 is fixedly connected to the inside of the sliding box 62.

[0040] Specifically, the system achieves automatic and continuous lubrication of the contact area between the guide rail 63 and the sliding box 62 in the operating component 6. The oil tank 101 serves as a storage unit for lubricating oil, stably storing a sufficient amount of lubricating oil. The square shell 102 is connected to the sliding box 62. When the sliding box 62 moves, the trapezoidal slider 103 inside is squeezed, forcing the lubricating oil to flow through the through hole 105 to the guide rail 63. The square groove 106 on the guide rail 63 stores this lubricating oil, continuously supplying oil to the contact area. The second spring 104 precisely provides a restoring force after the trapezoidal slider 103 is squeezed, allowing the trapezoidal slider 103 to return to its position, ensuring a continuous supply of lubricating oil, effectively reducing friction between the guide rail 63 and the sliding box 62, extending the service life of the equipment, and ensuring the stable and efficient operation of the operating component 6.

[0041] Working principle: The servo motor 21 starts and drives the harmonic reducer 22 to run. The harmonic reducer 22 transmits power to the rotating shaft 24 through the expansion coupling 23, which in turn drives the gear plate 32 to rotate on the top of the lower plate 31, realizing the flipping action of the worktable 7. When locking is required, multiple oil cylinders 41 inside the gear plate 32 are activated, pushing the clamping claws 42 to move along the T-slot 43, and using the clamping claws 42 to fix the workpiece.

[0042] The electric push rod 61 drives the sliding box 62 to move on the guide rail 63, adjusting the position above the worktable 7. The drive motor 65 drives the lead screw 66 to rotate, causing the moving frame 67 to move on the lead screw 66, achieving horizontal position adjustment. The drive motor 68 drives the lead screw 69 to rotate, causing the milling cutter 610 to move on the lead screw 69, achieving vertical position adjustment, thus enabling precise milling of the workpiece.

[0043] Water in water tank 83 flows to nozzle 87 through diversion pipe 86 under the action of water pump 85. Nozzle 87 sprays water onto workpieces and milling cutter 610 on worktable 7 for cooling. At the same time, fan 82 can accelerate air flow to assist in cooling. The guide channel 88 and filter plate 89 inside worktable 7 guide the cooled water back to water tank 83 through water inlet pipe 810 to achieve water circulation.

[0044] When water flows in the inlet pipe 810, it drives the rotating blade 92 on the rotating rod 91 to rotate. The rotating blade 92 drives the gear 93 to rotate. The gear 93 meshes with the gear 96, causing the rotating shaft 95 to rotate. The disc 97 and the limiting rod 98 on the rotating shaft 95 rotate accordingly. The limiting rod 98 drives the moving rod 911 to move up and down in the water tank 83 through the sleeve 99 and the connecting rod 910, which shakes the filter plate 84 to prevent impurities from clogging the filter plate 84 and ensures normal water circulation.

[0045] The lubricating oil in the oil tank 101 flows into the square housing 102. When the sliding box 62 moves on the guide rail 63, the trapezoidal slider 103 slides in the square housing 102. Under the action of the second spring 104, the lubricating oil flows through the through hole 105 to the guide rail 63, thereby lubricating the contact parts between the guide rail 63 and the sliding box 62, reducing friction, and ensuring smooth operation.

[0046] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
