Description

Technical Field

[0001] This invention relates to the field of machine tool component technology, specifically to an adaptive driven cutting fluid discharge device. Background Technology

[0002] Machine tool cutting fluid discharge devices are key components that provide cooling and lubrication for the workpiece and cutting tools during machine tool cutting processes. Their discharge efficiency and compatibility directly affect the machining accuracy, tool life, and cutting fluid utilization efficiency. Currently, most mainstream cutting fluid discharge devices on the market employ an external independent motor-driven pump operation mode. The motor drives the pump to draw cutting fluid from the storage container and deliver it to the machine tool's cutting area to meet the cooling and lubrication requirements during machining.

[0003] However, such traditional discharge devices have significant technical defects in practical applications. The core problem is that the cutting fluid discharge rate cannot be dynamically matched with the cutting speed of the machine tool spindle, which leads to cutting fluid waste or insufficient cutting fluid discharge. The specific drawbacks and causes are as follows: 1. Poor speed matching, unable to dynamically adjust according to cutting conditions: The cutting speed of the machine tool spindle is adjusted in real time according to the material, specifications, and processing requirements of the workpiece. However, the motor of the traditional discharge device is an independent drive unit, and its speed and pump discharge speed are fixed values. It cannot be synchronously and adaptively adjusted according to the real-time cutting speed of the machine tool spindle. When the spindle cutting speed decreases, the fixed high discharge speed will cause the cutting fluid supply to far exceed the actual processing needs, resulting in a large amount of ineffective consumption and waste of cutting fluid. When the spindle cutting speed increases, the fixed low discharge speed cannot provide sufficient cooling and lubrication for the high-speed cutting tool and workpiece, resulting in insufficient cutting fluid discharge.

[0004] 2. Independent drives increase equipment matching errors and further exacerbate the mismatch: The motor and the machine tool spindle are two independent drive systems with no linkage mechanism for their operation control. Time differences and speed matching errors are easily generated during equipment start-up, shutdown, and speed adjustment. It is impossible to achieve precise synchronization between the drainage speed and the cutting speed. Even if the motor speed is manually adjusted, it is difficult to keep up with the changes in the spindle cutting speed in real time. Moreover, manual adjustment has operational lag and accuracy deviation, which cannot meet the continuous and efficient processing requirements of the machine tool.

[0005] 3. Imbalance in cutting fluid leads to subsequent processing problems: When the cutting fluid is insufficient, the large amount of heat generated by high-speed cutting cannot be dissipated in time, which can easily cause thermal deformation of the workpiece surface and rapid wear of the tool due to high temperature, reducing the workpiece machining accuracy and tool life; excessive waste of cutting fluid not only increases the cost of consumables in the production process, but also increases the load of subsequent processes for cutting fluid recycling and treatment, which does not conform to the energy-saving and high-efficiency design concept of machine tool processing.

[0006] In summary, existing cutting fluid discharge devices driven by external motors suffer from poor adaptability to the machine tool spindle cutting speed due to the lack of an adaptive linkage mechanism. This leads to a series of drawbacks such as cutting fluid waste and insufficient cooling and lubrication, and can no longer meet the high-precision, high-efficiency, and energy-saving machining needs of modern machine tools. There is an urgent need to develop a cutting fluid discharge device that can dynamically adapt to the machine tool spindle cutting speed to overcome the shortcomings of existing technologies. Summary of the Invention

Each liquid compression chamber has a first liquid reserve chamber at its bottom end, and each first liquid reserve chamber has a first docking channel connecting to the outside space at its bottom end. Each first liquid reserve chamber has a second docking channel connecting to the outside space on its side. A first liquid check valve and a second liquid check valve are respectively installed inside the first and second docking channels. The body is a one-way valve. Each of the liquid compression chambers has a piston plate that can move along its axis. The upper surface of the piston plate has a concave hemispherical mounting groove. A rotatable ball head is placed in the hemispherical mounting groove. The top of the ball head is provided with an integral movable rod. A bushing is installed at the top of the movable rod. The shafts of the two Z-shaped crankshafts are mounted on the top of the irregular hollow shell through bearings and shaft mounting bases. Driven gears are fixedly installed at the opposite ends of the two Z-shaped crankshafts. The revolution shaft of the Z-shaped crankshafts is installed inside the bushing.

[0010] Preferably, the No. 1 liquid check valve and the No. 2 liquid check valve can control the liquid to enter the No. 1 liquid reserved chamber through the No. 1 docking channel and to be discharged outward through the No. 2 docking channel.

[0011] Preferably, the two Z-shaped crankshafts are arranged in a symmetrical staggered manner, and when the driven gear rotates, the two Z-shaped crankshafts drive the two piston plates to move in opposite directions longitudinally.

[0012] Preferably, the structural radius of the hemispherical mounting groove is adapted to the structural radius of the rotating ball head, and the depth of the hemispherical mounting groove is greater than the structural radius of the rotating ball head and less than the structural diameter of the rotating ball head.

[0013] Preferably, the buffered liquid discharge mechanism further includes three upper connecting plates integrally disposed at the bottom edge of the hollow cylinder. The top structure of the hollow cylinder is fixedly installed inside the main component mounting groove. A liquid buffer chamber is disposed inside the hollow cylinder. A second liquid reserve chamber is disposed at the bottom center of the liquid buffer chamber. A fourth docking channel communicating with the outside space is disposed at the bottom of the second liquid reserve chamber. Two symmetrical third docking channels communicating with the outside space are disposed on the side of the second liquid reserve chamber. Each third docking channel is fixedly connected to a corresponding second docking channel. A second piston plate capable of moving along its axial direction is placed inside the liquid buffer chamber. Multiple helical springs are fixedly installed above the second piston plate.

[0014] Preferably, the plurality of helical springs are arranged in a ring array on the top of the second piston plate, and the initial length of the helical springs is greater than the depth of the liquid buffer chamber.

[0015] Preferably, it also includes a distance-extending installation mechanism, the structure of which includes a component mounting plate that can be fixedly installed on the machine tool housing and multiple upper longitudinal connecting rods that are fixedly connected to the upper connecting plate and provide pipe installation space below the No. 4 docking channel.

[0017] Preferably, the three upper longitudinal links are arranged in a circular array at the edge of the upper surface of the branch connecting disc.

[0018] Compared with the prior art, the present invention provides an adaptive driven cutting fluid discharge device, which has the following advantages: 1. Achieve adaptive adjustment of fluid discharge speed to precisely match cutting conditions: The device is linked with the machine tool spindle drive gear through the meshing of the driven gear. The spindle rotation speed directly determines the cutting fluid delivery and discharge speed of the device. When the spindle speed increases, the fluid discharge speed increases synchronously, and when the spindle speed decreases, the fluid discharge speed decreases synchronously. This fundamentally solves the problem of fixed fluid discharge speed and disconnection from cutting speed in traditional devices, ensuring that the cutting fluid supply is always highly consistent with the actual machining needs.

[0019] 2. Significantly improve the effective utilization rate of cutting fluid and reduce production consumable costs: Based on the precise matching of the drainage speed and cutting conditions, the ineffective waste of cutting fluid caused by excessive drainage in traditional equipment is completely avoided, reducing the total consumption of cutting fluid. At the same time, it reduces the load and cost of subsequent processes such as cutting fluid recovery, filtration and treatment, taking into account both production economy and energy saving.

[0020] 3. Ensure timely cooling during the cutting process, improve machining quality and tool life: The device can simultaneously increase the discharge volume according to the high-speed cutting conditions of the spindle, continuously and adequately supply cutting fluid to the cutting part, and promptly remove the large amount of heat generated by high-speed cutting. This effectively avoids machining accuracy deviations caused by thermal deformation of the workpiece, while also alleviating the problem of rapid wear and chipping of tools due to high temperature, extending tool life, and stabilizing the product quality of machine tool processing.

[0021] 4. Uniform flow rate and stable pressure of the fluid enhance the cooling and lubrication effect: The two Z-shaped crankshafts of the device adopt a symmetrical staggered layout, which drives the No. 1 piston plate to move in opposite directions, so that the cutting fluid is delivered to the buffer mechanism at a uniform flow rate; the buffer mechanism, through the cooperation of the helical spring and the No. 2 piston plate, provides the cutting fluid with a continuous and stable discharge pressure, so that the cutting fluid can be continuously and smoothly sprayed to the cutting part, ensuring full contact between the cutting fluid and the tool and the workpiece, further improving the cooling and lubrication effect, and reducing frictional resistance and workpiece surface damage during the machining process.

[0022] 5. No additional independent drive unit, simplifying the structure and reducing the probability of failure: The device relies on the power of the machine tool spindle to achieve driven drive, without the need to set up an independent drive motor and matching control components. This simplifies the overall structure of the device, reduces the number of mechanical parts, reduces the coordination error and probability of failure caused by the linkage of multiple drive units, saves the power consumption of the motor drive, and makes the installation, debugging and maintenance of the device more convenient.

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

[0026] Please see Figure 1 and Figure 2 An adaptive driven cutting fluid discharge device is described. During operation, the component mounting plate 35 is fixedly installed on the internal housing of the machine tool with bolts, and the driven gear 115 is engaged with the gear that drives the machine tool spindle to rotate. Then, the two No. 1 docking channels 15 are connected to the drain port of a tank containing cutting fluid through pipes. Finally, the No. 4 docking channel 26 is connected to the pipe used to discharge cutting fluid.

[0027] To achieve precise matching between the cutting fluid discharge rate and the machine tool spindle speed, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A driven liquid drive mechanism 1 needs to be installed, the structure of which includes an irregularly shaped hollow shell 11 with a hollow internal structure, a driven gear 115 installed directly above the irregularly shaped hollow shell 11 and capable of rotation, two first piston plates 19 symmetrically installed inside the irregularly shaped hollow shell 11, two Z-shaped crankshafts 116 that rotate with the driven gear 115 and can drive the two first piston plates 19 to reciprocate, and a first liquid check valve 17 and a second liquid check valve 18 that can control the unidirectional drive of the cutting fluid. After the machine tool is started, the gear driving the machine tool spindle rotates synchronously and drives the workpiece to move. The driven gear 115 meshing with it rotates synchronously with the spindle gear. During the rotation of the driven gear 115, it drives the two Z-shaped crankshafts 116. The linkage drives the two piston plates 19 to reciprocate in opposite directions longitudinally. Under the unidirectional flow coordination of the first liquid check valve 17 and the second liquid check valve 18, the cutting fluid is continuously drawn into the liquid compression chamber 13 and stably pumped into the second liquid reserve chamber 24. Thanks to the symmetrical staggered layout design of the two Z-shaped crankshafts 116, the cutting fluid can enter the second liquid reserve chamber 24 at a uniform flow rate. At the same time, because the driven gear 115 directly meshes with the machine tool spindle gear, the delivery and discharge speed of the cutting fluid can be adaptively and dynamically matched with the rotation speed of the machine tool spindle. This ensures that the cutting fluid supply is in line with the machining conditions from the source, effectively improving the effective utilization rate of the cutting fluid, and ensuring the timely and sufficient cooling of the workpiece during the cutting process.

[0028] For the specific structure of the driven liquid drive mechanism 1, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5The driven liquid drive mechanism 1, as the core execution unit for the adaptive delivery of cutting fluid in this device, uses a hollow, irregularly shaped shell 11 as the overall basic support structure. Its structure is compact and the components are highly interconnected. The specific detailed structure and assembly relationship are as follows: The bottom of the hollow, irregularly shaped shell 11 is recessed to form a main component mounting groove 12, providing a precise installation and positioning foundation for subsequent docking with the buffered liquid discharge mechanism 2. On both sides of the main component mounting groove 12, the shell is integrally formed with liquid compression chambers 13 with open tops, serving as the core chambers for cutting fluid suction and compression. Each liquid compression chamber 13 has a first-level liquid reserve chamber 14 at its bottom, forming a temporary storage space for the cutting fluid, providing a buffer for stable delivery. Each first-level liquid reserve chamber 14 has a first-level docking channel 15 at its bottom and a second-level docking channel 16 on its side, both connecting to the external space and internally... A first liquid check valve 17 and a second liquid check valve 18 should be installed. Through the coordinated operation of the two check valves, the cutting fluid can be strictly controlled to enter the first liquid reserved chamber 14 in one direction only through the first docking channel 15, and then be discharged outward in one direction through the second docking channel 16. This achieves directional delivery of the cutting fluid and avoids backflow affecting delivery efficiency. A first piston plate 19 is slidably assembled inside the liquid compression chamber 13. It can reciprocate linearly along the axial direction of the chamber to provide power for the suction and pressure of the cutting fluid. A hemispherical mounting groove 110 is machined inward on the upper surface of the first piston plate 19. A rotating ball head 111 is movably placed in the groove, and the structural radius of the hemispherical mounting groove 110 is perfectly matched with the rotating ball head 111. The depth of the groove is greater than the structural radius of the rotating ball head 111 and less than its structural diameter. This size design ensures the flexible rotation of the rotating ball head 111 in the groove and effectively restricts its radial and axial movement to prevent it from falling off. The top of the rotating ball head 111 is integrally formed with a movable rod 112, and a bushing 113 is fixedly installed at the top of the rod, providing an assembly node for linkage with the crankshaft. The shafts of the two Z-shaped crankshafts 116 are horizontally installed on the top of the irregular hollow shell 11 via bearings and shaft mounting bases 114, ensuring the smoothness and coaxiality of the crankshaft rotation. The opposite ends of the two Z-shaped crankshafts 116 are jointly fixedly installed with driven gears 115, and the revolution shaft of the crankshaft is nested inside the bushing 113 to realize the transmission connection between the crankshaft and the piston plate. The two Z-shaped crankshafts 116 adopt a symmetrical staggered layout. When the driven gear 115 is driven to rotate by the machine tool spindle gear, it can drive the two No. 1 piston plates 19 to perform reverse reciprocating motion in the longitudinal direction, forming an alternating suction and pressure working mode.

[0029] To achieve the buffering and pressure stabilizing effect of the cutting fluid and ensure that it is continuously sprayed onto the workpiece cutting area at a constant pressure, please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 6 and Figure 7A buffered liquid discharge mechanism 2 needs to be installed. Its structure includes a hollow cylinder 21 fixedly installed at the center of the irregularly shaped hollow shell 11, a second piston plate 27 placed inside the hollow cylinder 21 and capable of upward movement under liquid pressure, and a helical spring 28 that exerts downward elastic pressure on the second piston plate 27. When the driven liquid drive mechanism 1 continuously delivers cutting fluid to the buffered liquid discharge mechanism 2, the continuously flowing cutting fluid creates an upward hydraulic thrust on the second piston plate 27, pushing it to move axially upward along the hollow cylinder 21. At this time, the cutting fluid... The cutting fluid is stably sealed in the cavity below the second piston plate 27, completing the buffering and collection of the cutting fluid. The helical spring 28, which moves upward with the second piston plate 27, is compressed synchronously, generating a reverse elastic rebound force. This force continuously acts on the second piston plate 27 and forms a stable pressure suppression on the cutting fluid buffered below. Through the dynamic balance between the hydraulic thrust and the spring elastic pressure, the buffered cutting fluid always maintains a stable pressure flow, effectively avoiding the problem of uneven spraying caused by cutting fluid pressure fluctuations. Ultimately, the cutting fluid is continuously sprayed to the cutting area of ​​the workpiece at a constant and uniform pressure, ensuring the stability of the cooling and lubrication effect.

[0030] For details regarding the specific structure of the buffered liquid discharge mechanism 2, please refer to [link / reference]. Figure 6 and Figure 7The buffered liquid discharge mechanism 2, as a key unit for the device to achieve stable pressure stabilization, buffering, and discharge of cutting fluid, is precisely assembled in the central main component mounting slot 12 of the irregular hollow shell 11 of the driven liquid drive mechanism 1. With the hollow cylinder 21 as the core carrier, the overall structure is seamlessly connected with the driven liquid drive mechanism 1. The components are compactly arranged and functionally coordinated. Its refined structure, assembly, and working details are as follows: The hollow cylinder 21 is an integrated hollow structure and serves as the basic support of the mechanism. Its top is precisely fixed to the main component mounting slot 12 of the irregular hollow shell 11, achieving a rigid connection with the driven liquid drive mechanism 1 and ensuring assembly stability. The bottom edge of the cylinder has three integrated upper connecting plates 22, which provide standardized assembly nodes for the docking of this mechanism with the subsequent extended-distance installation mechanism 3, ensuring the firmness and coaxiality of the connection. The hollow cylinder 21 has a liquid buffer chamber 23 inside, which serves as the core chamber for stabilizing and buffering the cutting fluid. Its bottom center contracts inward to form a second liquid reserve chamber 24, which becomes a transitional storage space for the cutting fluid before it enters the discharge channel, enabling secondary collection of the cutting fluid and ensuring continuous discharge. Two third-level docking channels 25 are symmetrically opened on the side of the second liquid reserve chamber 24. Each third-level docking channel 25 corresponds one-to-one with and is sealed and fixedly connected to the second-level docking channel 16 on the side of the driven liquid drive mechanism 1, forming a dedicated channel for the cutting fluid to be transported from the drive mechanism to the buffer mechanism, ensuring that the cutting fluid can enter the mechanism smoothly and without leakage. A fourth-level docking channel 26 is opened at the bottom of the second liquid reserve chamber 24, serving as the only channel for the final external discharge of the cutting fluid. It is sealed and connected to the external cutting fluid injection pipe to achieve the desired cutting fluid discharge. The fluid is directed to the cutting part of the machine tool. A second piston plate 27 is slidably mounted inside the fluid buffer chamber 23. It can move flexibly and without jamming along the axial direction of the hollow cylinder 21. Its outer wall is tightly fitted with the inner wall of the fluid buffer chamber 23 to ensure the sealing performance of the chamber and effectively prevent the cutting fluid from leaking. Multiple helical springs 28 are fixedly installed on the top of the second piston plate 27 in a ring array. The top of all helical springs 28 abuts against the top inner wall of the fluid buffer chamber 23. The initial free length of the helical springs 28 is greater than the depth of the fluid buffer chamber 23. This size design allows the helical springs 28 to be in a slightly compressed state in their natural state, which can provide continuous initial downward elastic pressure to the second piston plate 27. This ensures that when the mechanism is not working, the second piston plate 27 is always in contact with the bottom of the fluid buffer chamber 23, making full use of the fluid storage space of the chamber.

[0031] To ensure sufficient space for pipe installation and docking below docking channel 26 (number four), and to ensure precise assembly of the device and machine tool, as well as effective meshing of driven gear 115 and machine tool spindle drive gear, please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 8An extended-distance installation mechanism 3 needs to be set up. Its structure includes a component mounting plate 35 that can be fixedly installed on the machine tool housing and multiple upper longitudinal connecting rods 32 that are fixedly connected to the upper connecting plate 22 and provide pipe installation space below the fourth docking channel 26. When the component mounting plate 35 is firmly installed in the machine tool housing by bolts, it can accurately adjust the overall installation height of the device to ensure that the driven gear 115 and the machine tool spindle drive gear can achieve precise meshing and efficient power transmission. It can also reserve enough operating and installation space below the fourth docking channel 26 to facilitate the sealed connection between the external cutting fluid discharge pipe and the fourth docking channel 26, ensuring the convenience of pipe connection and assembly stability.

[0032] For details regarding the specific structure of the extended mounting mechanism 3, please refer to [link / reference]. Figure 8 The extended-distance mounting mechanism 3 is the core support unit for this device to achieve a stable connection with the machine tool housing and flexible adjustment of the installation height. It provides a stable installation foundation for the buffered liquid discharge mechanism 2 and the driven liquid drive mechanism 1, while ensuring sufficient space for pipe assembly below the No. 4 docking channel 26. Its overall structure is hierarchical and the assembly nodes are standardized. It is seamlessly connected with the buffered liquid discharge mechanism 2. The refined structure and assembly details are as follows: The mechanism is based on the component mounting plate 35 as the fixed end. It can be rigidly and stably connected to the internal machine tool housing through bolts, providing reliable installation support for the entire device and ensuring that the device does not loosen or shift under the conditions of high-speed operation and vibration of the machine tool. The upper surface of the component mounting plate 35 is integrally formed with a lower longitudinal connecting rod 34. The connecting rod is arranged vertically with the mounting plate to ensure vertical force transmission and improve the stability of the structural support. A branch connecting plate 31 is fixedly installed at the top of the lower longitudinal connecting rod 34, serving as the intermediate connecting hub of the mechanism. This allows for the distributed transmission of force from a single connecting rod to multiple connecting rods, while also providing a standardized mounting base for the upper longitudinal connecting rod 32. Three upper longitudinal connecting rods 32 are evenly installed in a circular array along the edge of the upper surface of the branch connecting plate 31. The three connecting rods are distributed at equal angles, forming a triangular support structure, which evenly distributes the weight of the upper mechanism to the branch connecting plate 31, preventing structural deformation caused by concentrated force. A lower connecting plate 33 is fixedly installed at the top of each upper longitudinal connecting rod 32, and the lower connecting plate 33 connects to the upper connecting plate 22 at the bottom of the buffered liquid discharge mechanism 2. The one-to-one correspondence and sealed fixed connection achieves precise docking between the distance-extending installation mechanism 3 and the buffer liquid discharge mechanism 2, ensuring the coaxiality of the entire device assembly and reducing mechanical operation losses caused by assembly deviations. The entire mechanism forms a flexibly adjustable longitudinal support structure through the combination of the lower longitudinal connecting rod 34 and the upper longitudinal connecting rod 32. Depending on the internal layout of different machine tools and the position of the spindle gear, different lengths of the lower longitudinal connecting rod 34 or the upper longitudinal connecting rod 32 can be selected to precisely adjust the overall installation height and longitudinal spacing of the device, taking into account the precise meshing of the driven gear 115 and the machine tool spindle drive gear, as well as the pipe installation space requirements below the fourth docking channel 26.

[0033] In use, the component mounting plate 35 is fixed to the internal housing of the machine tool with bolts, and the driven gear 115 is engaged with the gear that drives the machine tool spindle. Then, the two No. 1 docking channels 15 are connected to the drain port of a tank containing cutting fluid through pipes. Finally, the No. 4 docking channel 26 is connected to the pipe used to discharge the cutting fluid. When the machine tool is driven, the gear that drives the machine tool spindle will rotate, thereby driving the workpiece to rotate. At this time, the driven gear 115 will rotate accordingly. During the rotation of the driven gear 115, the two Z-shaped crankshafts 116 drive the two No. 1 piston plates 19 to move in opposite directions longitudinally. The No. 1 liquid check valve 17 and the No. 2 liquid check valve 19 are connected to the machine tool spindle. With the cooperation of the one-way valve 18, the cutting fluid is continuously drawn into the liquid compression chamber 13 and continuously forced into the second liquid pre-reserved chamber 24. Due to the symmetrical and staggered design, the cutting fluid enters the second liquid pre-reserved chamber 24 at a relatively uniform flow rate. The continuously entering cutting fluid will exert an upward force on the second piston plate 27, causing the second piston plate 27 to move upward. The cutting fluid will be compressed in the cavity below the second piston plate 27. At the same time, the helical spring 28 in the compressed state can keep the cutting fluid under pressure and flow at all times, thereby achieving buffering of the cutting fluid, so that the cutting fluid can be sprayed onto the cutting part of the workpiece at a stable pressure.

[0034] 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.
