Description

Technical Field

[0001] This utility model relates to the technical field of five-axis gantry machining centers with milling heads, and more specifically, to a multi-functional five-axis gantry machining center with milling heads. Background Technology

[0002] In the field of modern precision manufacturing, the multi-functional milling head five-axis gantry machining center, as a high-end CNC machining equipment, directly affects the manufacturing quality and production efficiency of parts due to its machining accuracy and stability. However, the multi-functional milling head five-axis gantry machining centers on the market today have significant technical defects in terms of the practicality and reliability of their cooling systems. These problems not only affect the machining quality but may also lead to a reduction in the service life of the equipment.

[0003] The primary problem is poor heat dissipation. Existing multi-functional milling head five-axis gantry machining centers have significant temperature control obstacles: First, during high-speed cutting, the intense friction between the tool and the workpiece generates a large amount of heat, which can cause thermal deformation of the milling head components. In addition, the increased surface temperature of the workpiece can affect the machining performance of the material. This problem of insufficient heat dissipation not only reduces machining accuracy but also accelerates tool wear and may even lead to a decline in the surface quality of the workpiece, seriously affecting the product qualification rate.

[0004] A more challenging issue is the ineffective cooling control. While some improved machining centers are equipped with coolant systems, they suffer from a critical flaw: insufficient flow rate adjustment. First, traditional cooling systems typically employ a fixed flow rate design, making dynamic adjustment impossible based on varying operating conditions. Second, the heat dissipation requirements differ significantly depending on the material and cutting parameters, making a fixed flow rate insufficient for diverse machining needs. Third, excessive coolant flow can lead to resource waste and environmental pollution, while insufficient flow fails to achieve the desired cooling effect. Furthermore, different machining stages have varying cooling requirements, necessitating adjustments to coolant parameters for optimal performance. Finally, this ineffective cooling control not only results in uneven cooling but can also lead to energy waste and increased machining costs.

[0005] The most serious problem is the instability of the regulating structure. Although some high-end machining centers have achieved adjustable coolant flow, they suffer from serious defects in structural stability. First, most existing flow regulating devices lack a precise self-locking mechanism. During processing, the equipment will generate continuous mechanical vibrations, which will have a cumulative effect on the regulating structure. Second, the continuous impact of coolant can also cause the internal components of the regulating mechanism to loosen and shift. This instability of the regulating structure not only makes it impossible to keep the adjusted cooling parameters stable, but may also cause sudden changes during equipment operation, affecting the consistency of processing quality, increasing quality risks, and may even lead to equipment failure or increased maintenance costs.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a multi-functional five-axis gantry machining center with milling head, which has the following advantages:

[0019] 1. The cooling device constructs a complete cooling circulation system through the rational configuration of nozzles, delivery pipes, and a water chiller. The design of the water chiller provides cooling power for the overall system, the configuration of the delivery pipes enables directional delivery of coolant, and the setting of the nozzles ensures precise spraying of coolant. This structure not only adapts to the positional changes during equipment movement through the design of the corrugated pipes, but also achieves stable support for the pipeline through the setting of the fixing plate. Furthermore, the combination of the buffer tank and the return pipe establishes a coolant recycling system. At the same time, the through-hole design ensures effective collection of coolant, effectively solving the problem of poor heat dissipation in traditional machining centers, providing a continuous and stable cooling effect, and significantly improving the temperature control performance during the machining process.

[0020] 2. The control device forms a precise flow regulation system through the coordinated work of the control sleeve, driven wheel, control plate, mating pipe, drive gear, and rotating shaft. The rotational design of the control sleeve and mating pipe provides the basis for regulation, the meshing of the drive gear and driven wheel achieves precise transmission, and the configuration of the control plate and flow holes ensures controllable flow. This structure not only achieves precise flow regulation through gear transmission, but also achieves continuous adjustment of the flow area through angle changes, effectively solving the problem of unresponsive cooling control in traditional machining centers, realizing dynamic regulation of coolant flow, and meeting the cooling needs under different working conditions.

[0021] 3. The locking mechanism, through the precise cooperation of the locking sleeve, guide rail, locking block, linkage spring, linkage block, and guide groove, constructs a reliable positioning system. The threaded connection between the locking sleeve and the delivery pipe provides the locking basis, the cooperation between the guide rail and the guide groove realizes motion guidance, and the setting of components such as the linkage spring and linkage block ensures reliable positioning. This structure not only achieves stable position limitation through the cylindrical locking block, but also provides smooth transition movement through the linkage wheel. It effectively solves the problem of instability in the traditional machining center coolant delivery speed adjustment structure, resists the influence of equipment vibration and coolant impact, and ensures the stability of parameters after flow adjustment.

The active gear 10 is fixedly connected to the inner wall of the control sleeve 6 and is fixedly set at one end of the mating tube 9. The active gear 10 meshes with the driven wheel 7. A locking mechanism is provided on the outside of the conveying tube 4. The locking mechanism includes a locking sleeve 12, a guide rail 13, a locking block 14, a linkage spring 15, a linkage block 16, and a guide groove 17. The locking sleeve 12 is movably installed on the outside of the conveying tube 4 by threads. Multiple guide rails 13 are fixedly installed on one side of the control sleeve 6. Multiple locking blocks 14 are fixedly installed on the outside of the conveying tube 4. The two ends of the linkage spring 15 are respectively connected to two adjacent linkage blocks 16. The linkage block 16 is movably set on one side of the control sleeve 6. The guide groove 17 is opened in the linkage block 16 and is adapted to the guide rail 13.

[0031] The lifting assembly 2 is provided with fixed frames 18 on both sides, and a sliding assembly 19 is slidably provided above the fixed frames 18. The lifting assembly 2 is slidably installed on one side of the sliding assembly 19. A buffer compartment 20 is provided below the sliding assembly 19. A placement plate 21 is detachably provided on the buffer compartment 20. Multiple through holes 22 are provided on the placement plate 21.

[0032] The input end of the water chiller 5 is connected to a return pipe 23. The input end of the water chiller 5 is connected to the bottom of the buffer chamber 20 through the return pipe 23. Multiple corrugated pipes 24 are provided on the delivery pipe 4.

[0033] A fixing plate 25 is fixedly installed on one side of the fixing frame 18, above the sliding assembly 19, and on the outside of the lifting assembly 2. The conveying pipe 4 is detachably connected to the fixing plate 25.

[0034] In this embodiment, when the equipment is needed, the coolant delivery speed is first adjusted, then the workpiece to be processed is placed on the placement plate 21. The sliding assembly 19 is then opened, causing it to move the lifting assembly 2 and the drive assembly 1. The sliding assembly 19 also drives the bellows 24 at one end to stretch or compress via the delivery pipe 4. Once the desired position is reached, the sliding assembly 19 is closed, and the lifting assembly 2 slides along the sliding assembly 19, causing it to move the drive assembly 1. The lifting assembly 2 also drives the bellows 24 at the other end to stretch or compress via the fixing plate 25 and the delivery pipe 4. Finally, the lifting assembly is opened. 2. The drive assembly 1 drives the nozzle 3 to descend, and the bellows 24 on one side of the lifting assembly 2 is stretched. Then, the drive assembly 1 drives the milling head to process the part. Then, the water chiller 5 is turned on, and the water chiller 5 cools the coolant. Then, the water chiller 5 delivers the coolant to the delivery pipe 4 through the built-in delivery pump, and then delivers it to the nozzle 3 through the bellows 24 and the delivery pipe 4, so that the nozzle 3 sprays towards the processing position and the milling head position, thereby cooling the parts and the milling head and ensuring processing performance. Then, the sprayed coolant will enter the buffer chamber 20 set below through the through hole 22, and then be pumped back into the water chiller 5 for recycling through the return pipe 23.

[0035] Please see Figures 3-5 As a further implementation method for the overall equipment: the control plate 8 is provided with multiple flow holes 26.

[0036] Multiple rubber strips 27 are fixedly provided on the outer sides of both the regulating sleeve 6 and the locking sleeve 12.

[0037] The locking block 14 is designed as a column structure.

[0038] A linkage wheel 28 is provided on one side of the linkage block 16, which is rotated and engages between the two corresponding locking blocks 14.

[0039] More specifically, when the coolant delivery flow rate needs to be adjusted, firstly, the locking sleeve 12 is rotated forward. The locking sleeve 12 moves along the thread on the outer wall of the delivery pipe 4. Then, the locking sleeve 12 no longer limits the outer side of the linkage wheel 28. Then, the regulating sleeve 6 is rotated forward. The regulating sleeve 6 drives the guide rail 13 fixed on one side to rotate forward. Then, the guide rail 13 and the guide groove 17 cooperate to drive the linkage block 16 to rotate forward. Then, the linkage block 16 drives the linkage wheel 28 to roll out between the two locking blocks 14. Then, the linkage wheel 28 drives the linkage block 16 to slide outward along the guide rail 13 and the guide groove 17. Then, the linkage block 16 drives the linkage spring 15 to stretch outward. At the same time, the regulating sleeve 6 drives the mating tube 9 set on the inner side to rotate forward. Then, the mating tube 9 drives the active gear 10 set on one side to rotate. Then, the active gear 10 synchronously drives multiple driven wheels 7 to rotate along the rotating shaft 11. Then, the driven wheels 7 drive the regulating plate 8 to rotate, so that the regulating plate 8... The angle of the control sleeve 6 changes, causing the control plate 8 to change the angle of the flow hole 26, which in turn changes the flow area at the corresponding position inside the conveying pipe 4, thereby changing the conveying flow rate. After the adjustment is appropriate, the control sleeve 6 is stopped from rotating, and the guide rail 13 and guide groove 17 work together to move the linkage block 16 between the two corresponding locking blocks 14. Then, the linkage spring 15 resets and pulls the linkage block 16 to slide inward along the guide rail 13 and guide groove 17, so that the linkage block 16 drives the linkage wheel 28 to engage between the two corresponding locking blocks 14. Then, the locking sleeve 12 is rotated in the opposite direction, so that the locking sleeve 12 moves and resets along the thread. Then, the inner wall of the locking sleeve 12 limits the outer wall of the linkage wheel 28, so that the linkage wheel 28 and the linkage block 16 cannot move outward, thereby achieving the positioning and locking of the control sleeve 6, preventing the control sleeve 6 from rotating, thus ensuring the structural stability after the flow rate adjustment and ensuring stable processing.

[0040] In summary, when using or operating the entire equipment: First, adjust the coolant delivery speed. Then, place the workpiece to be processed on the placement plate 21. Next, open the sliding assembly 19, causing it to move the lifting assembly 2 and the drive assembly 1. The sliding assembly 19 will also stretch or compress one end of the bellows 24 via the delivery pipe 4. After adjusting to the appropriate position, close the sliding assembly 19. Then, allow the lifting assembly 2 to slide along the sliding assembly 19, causing it to move the drive assembly 1. The lifting assembly 2 will stretch or compress the other end of the bellows 24 via the fixed plate 25 and the delivery pipe 4. Then, open... The lifting assembly 2 causes the drive assembly 1 to drive the nozzle 3 to descend, and the bellows 24 on one side of the lifting assembly 2 to stretch. Then, the drive assembly 1 is turned on to drive the milling head to process the part. Then, the water chiller 5 is turned on to cool the coolant. The water chiller 5 then delivers the coolant to the delivery pipe 4 through the built-in delivery pump. Then, it is delivered to the nozzle 3 through the bellows 24 and the delivery pipe 4, so that the nozzle 3 sprays towards the processing position and the milling head position to cool the parts and the milling head and ensure processing performance. Then, the sprayed coolant will enter the buffer tank 20 set below through the through hole 22, and then be pumped back into the water chiller 5 for recycling through the return pipe 23.

[0041] When the coolant delivery flow rate needs to be adjusted, firstly, rotate the locking sleeve 12 clockwise. The locking sleeve 12 moves along the thread on the outer wall of the delivery pipe 4. Then, the locking sleeve 12 no longer limits the outer side of the linkage wheel 28. Then, rotate the regulating sleeve 6 clockwise. The regulating sleeve 6 drives the guide rail 13 fixed on one side to rotate clockwise. Then, the guide rail 13 and the guide groove 17 cooperate to drive the linkage block 16 to rotate clockwise. Then, the linkage block 16 drives the linkage wheel 28 to roll out between the two locking blocks 14. Then, the linkage wheel 28 drives the linkage block 16 to slide outward along the guide rail 13 and the guide groove 17. Then, the linkage block 16 drives the linkage spring 15 to stretch outward. At the same time, the regulating sleeve 6 drives the mating tube 9 set on the inner side to rotate clockwise. Then, the mating tube 9 drives the driving gear 10 set on one side to rotate. Then, the driving gear 10 synchronously drives multiple driven wheels 7 to rotate along the rotating shaft 11. Then, the driven wheels 7 drive the regulating plate 8 to rotate, so that the angle of the regulating plate 8... The angle of the flow hole 26 caused by the change in the degree of flow rate is changed by the control plate 8, which in turn changes the flow area at the corresponding position inside the conveying pipe 4, thereby changing the conveying flow rate. After the adjustment is appropriate, the rotation of the control sleeve 6 is stopped, and the guide rail 13 and the guide groove 17 cooperate to move the linkage block 16 between the two corresponding locking blocks 14. Then, the linkage spring 15 resets and pulls the linkage block 16 to slide inward along the guide rail 13 and the guide groove 17, so that the linkage block 16 drives the linkage wheel 28 to engage between the two corresponding locking blocks 14. Then, the locking sleeve 12 is rotated in the opposite direction, so that the locking sleeve 12 moves and resets along the thread. Then, the inner wall of the locking sleeve 12 limits the outer wall of the linkage wheel 28, so that the linkage wheel 28 and the linkage block 16 cannot move outward, thereby achieving the positioning and locking of the control sleeve 6, preventing the control sleeve 6 from rotating, thus ensuring the structural stability after the flow rate adjustment and ensuring stable processing.

For all the fixed connections mentioned above, welding is preferred.
