Description

Technical Field

[0001] The present application relates to the technical field of numerical control equipment, and in particular to a five-axis numerical control machine tool. Background Art

[0002] Five-axis machining centers are capable of high-precision machining of complex surfaces in three-dimensional space. In actual production, high-speed friction between the workpiece and the tool generates a large amount of cutting heat, for which an emulsion or cutting fluid injection system is usually used for circulating cooling. However, the metal scraps generated during the turning process mix with the emulsion to form a solid-liquid mixture. After machining, the scraps need to be separated from the coolant for recycling and reuse. Traditional manual sorting methods are inefficient and pose safety risks. If an external independent filtering and separation device is connected, it will not only increase the equipment cost, but also significantly increase the machine tool footprint, resulting in limited equipment placement.

[0025] The following combination Figures 1 to 6 The embodiments of the present application are described.

[0026] The present application provides a five-axis CNC machine tool, which includes a frame, a tool mechanism 200, a placement mechanism 300 and a collection mechanism; the frame is provided with a workbench 110 and a collection chamber 120, and the workbench 110 is provided above the collection chamber 120;

[0027] The tool mechanism 200 is disposed on the workbench 110 ; the placement mechanism 300 is disposed on the workbench 110 and is arranged opposite to the tool mechanism 200 ;

[0028] The collecting mechanism includes a chip removal groove, a liquid drainage groove and a separation component 430. The chip removal groove and the liquid drainage groove are both arranged in the collecting chamber 120. The separation component 430 includes a separation tube 431, a transmission rod 432, a spiral leaf spring 433 and a driving device. The transmission rod 432 and the spiral leaf spring 433 are both arranged in the separation tube 431. The spiral leaf spring 433 is sleeved and fixed on the outside of the transmission rod 432. There are spiral leaves on the bolt spring. The driving device and the transmission rod 432 Transmission connection, the separation tube 431 has a feed end 4311 and a discharge end 4312, the workbench 110 is provided with a waste outlet, the feed end 4311 is connected to the waste outlet, a plurality of filter holes 4313 are provided on the feed end 4311, the drainage trough and the feed end 4311 are connected to the side close to the filter hole 4313 through a pipeline, so that the cutting fluid flows out along the filter hole 4313 and flows to the drainage trough along the pipeline, and the discharge end 4312 is connected to the chip discharge trough.

[0029] In this way, when the machine tool is running, the solid-liquid mixture formed by the mixture of metal scraps and cooling waste liquid flows into the feed end 4311 of the separation tube 431 through the waste outlet of the workbench 110. The waste liquid flows into the drainage trough through the filter hole 4313 of the feed end 4311, while the waste chips are trapped in the feed end 4311. The driving device drives the transmission rod 432 to rotate, and the spiral leaf spring 433 on the transmission rod 432 pushes the waste chips to move along the separation tube 431 toward the discharge end 4312, and finally falls into the chip discharge trough to realize the functions of waste collection, waste liquid discharge, and waste chip discharge. It can be understood that in order to facilitate the display of the internal structure, Figure 1 The entire machine casing for covering the workbench to prevent splashing in the machine tool shown is not shown.

[0030] Optionally, the separation tube 431 is tilted upward at one end away from the feed end 4311 to prevent the liquid from flowing along the discharge end into the chip removal chamber. At the same time, the waste chips are driven by the spring of the spiral blade 433 to move along the tilted separation tube and finally discharged from the chip removal chamber.

[0031] Traditional external multiple filtering and separation equipment will significantly increase the size of the machine tool, limit its placement, and have low solid-liquid separation efficiency. Therefore, by providing a collection mechanism at the bottom of the frame, when the machine tool is running, the solid-liquid mixture formed by the mixture of metal scraps and cooling waste liquid will flow directly into the collection mechanism through the waste outlet. The scraps are efficiently intercepted at the feed end 4311, and the waste liquid can flow directly into the drainage trough below through the filter hole 4313, achieving preliminary solid-liquid separation. At the same time, the drive device drives the spiral blade spring 433 to rotate. Under the push of the spiral blade spring 433, the scraps accumulated at the feed end 4311 move along the internal channel of the separation tube 431 toward the discharge chamber, and are finally pushed into the chip discharge chamber for centralized collection. In this way, the functions of waste collection, waste liquid discharge, and waste chip discharge are integrated at the bottom of the machine tool. The waste can be processed after processing without manual sorting, and the space occupied can be significantly reduced, providing conditions for the miniaturization of the machine tool.

[0032] Optionally, the liquid drain trough and the chip trough are arranged in upper and lower layers within the collection chamber, with the liquid drain trough located at the bottom of the collection chamber, the separation tube and the chip trough both located at the upper end of the liquid drain trough, and the separation tube located on one side of the chip trough. This upper and lower layered design reduces the horizontal footprint of the collection chamber, providing a foundation for miniaturization of machine tools. Meanwhile, waste chips are pushed from the feed end of the separation tube to the chip trough via a spiral blade spring. Waste liquid flows through the filter holes into the liquid drain trough and ultimately flows to an external circulation pipe, separating the waste liquid from the waste chip collection path.

[0033] Still optionally, a liquid level gauge and a magnetic component are provided within the drain trough. The liquid level gauge is located on one side of the trough, and the magnetic component is fixed to the bottom of the trough for monitoring the liquid level and absorbing waste chips. Exemplarily, the magnetic component is a magnet. When coolant containing metal chips flows into the drain trough through the filter holes at the feed end, the chips, primarily composed of steel and having a certain magnetic property, are attracted to the surface of the magnetic component, further separating and collecting the chips from the coolant and further enhancing the machine tool's waste processing capabilities.

[0034] In the actual operation of five-axis machining centers, when chips accumulate over a large area before the chip conveyor is started, the spiral blades are prone to clogging. Once clogged, the rotation of the drive motor is hindered, causing the operating current to rise sharply. When the current exceeds the rated value, the thermal protection device can be triggered in time to cut off the circuit to protect the equipment. However, due to the extremely rapid current surge, the motor often burns out due to overheating before the thermal protection device is activated. Even if the thermal protection device is activated normally, after the fault is reset, the operator still needs to manually control the spiral chip conveyor for multiple forward and reverse adjustments to try to remove the blockage. If the blockage is severe, manual cleaning is required, which seriously affects the production schedule and the normal operation efficiency of the equipment.

[0035] Therefore, in some embodiments, the separation assembly 430 further includes at least two sensor plates and a proximity switch, the proximity switch being provided on the separation tube 431 , and at least two of the sensor plates being spaced apart along the circumferential direction of the transmission rod 432 and being provided close to the proximity switch.

[0036] In actual use, the sensing sheet can be an iron sheet. The proximity switch is fixed on the separation tube 431, and at least two sensing sheets are installed at intervals in the circumferential direction of the transmission rod 432. During installation, ensure that the sensing sheet is firmly fixed to the rotating shaft to avoid displacement or falling off of the sensing sheet due to vibration during the operation of the separation component 430. At the same time, adjust the distance between the sensing sheet and the proximity switch to control it within the effective detection range of the proximity switch, and ensure that the sensing sheet and the proximity switch maintain an appropriate detection distance to ensure reliable signal detection.

[0037] The controller is electrically connected to the proximity switch. The sensor plate on the circumferential axis of the transmission rod 432 rotates with it. The proximity switch detects the sensor plate signal and transmits it to the controller. The controller continuously receives the sensing signal collected by the proximity switch. For example, during normal operation, the sensor plate rotates with the transmission rod 432, and the proximity switch outputs a signal. The controller can determine the operating speed of the separation assembly 430 by calculating the time interval between adjacent signals. It can also identify the forward and reverse rotation direction of the separation assembly 430 based on the sequence of the signals. The presence and duration of the signal can also determine whether the separation assembly 430 is in operation or stalled.

[0038] After the separation assembly 430 is activated, the controller monitors the proximity switch signal. If the proximity switch fails to detect a signal from the sensor within a preset time, the controller determines that the separation assembly 430 is stalled. Once the controller determines that the separation assembly 430 is stalled, it controls the circuitry to change the current flow to the separation assembly 430's drive motor, thereby switching the motor's rotation direction to the reverse direction. During reverse operation, the controller continues to monitor the proximity switch signal.

[0039] When the proximity switch detects two or more sensor signals, it indicates that the spindle of separation assembly 430 has resumed rotation. After confirming that the blockage has been cleared, the controller again controls the circuit to change the direction of the current flowing to the drive motor, automatically switching separation assembly 430 back to the predetermined forward rotation mode. Separation assembly 430 resumes normal operation, and the controller continues to monitor its operation to ensure stable operation.

[0040] If the number of forward and reverse switching cycles of separation assembly 430 reaches a preset upper limit and the system still fails to detect a sensor signal, the controller will determine that separation assembly 430 is severely blocked. At this point, the controller issues a control command to stop the power supply to separation assembly 430, causing transmission rod 432 to stop rotating, thereby preventing further damage to the equipment caused by continued stalling. At the same time, a prominent alarm prompt screen can be popped up through the human-computer interface to display specific fault information.

[0041] In some embodiments, the driving device 500 includes a motor 510, a driving wheel 520, a driven wheel 540, and a transmission belt 530. The motor 510 is fixed to one side of the separation tube 431, the driven wheel 540 is fixed to one end of the transmission rod 432, the driving wheel 520 is connected to the output shaft of the motor 510, and the driving wheel 520 and the driven wheel 540 are connected by the transmission belt 530. The motor 510 drives the driving wheel 520 to rotate, the driving wheel 520 drives the driven wheel 540 to rotate via the transmission belt 530, the driven wheel 540 drives the transmission rod 432 to rotate, and the transmission rod 432 drives the spiral blade spring to rotate, thereby driving the waste chips along the pipeline direction of the separation tube through the spiral body for chip removal.

[0042] In some embodiments, the tool mechanism 200 includes a tool head 210 for processing and a first guide assembly 220 for movement along the Z-axis. The first guide assembly 220 includes a first slide rail 221 and a first slide plate 222. The first guide rail is vertically arranged and fixed to the workbench 110. The first slide plate 222 is slidably connected to the first slide rail 221. The tool head 210 is fixed to the first slide plate 222. Optionally, to meet the needs of multi-process integrated processing, a tool storage position for replacing tool holders is provided on one side of the tool mechanism. The tool storage position includes multiple tool holders and a tool changing mechanism.

[0043] During actual assembly, the motor drives the first slide 222 to slide up and down along the first slide rail 221 in the Z-axis direction, causing the tool head 210 fixed to the first slide 222 to move accordingly, adjusting the position of the tool in the Z-axis direction and thus processing the workpiece on the workbench 110. The first slide rail 221 drives the tool head 210 to achieve linear motion along the Z-axis, meeting different processing height requirements.

[0044] In some embodiments, the placement mechanism 300 includes a cradle device 310 for rotating around the Y-axis and a rotating device 320 for rotating around the Z-axis. The workbench 110 is provided with a base 130. The cradle device 310 includes a fixed frame 311 and a cradle seat 312. The fixed frame 311 is fixed on the base 130. The cradle seat 312 is rotatably connected to the fixed frame 311. The rotating device 320 is provided on the cradle seat 312, and the rotating device 320 is provided with a processing seat 321 for placing the workpiece.

[0045] Furthermore, the placement mechanism 300 also includes a second guide assembly 330 for moving along the Y-axis and a third guide assembly 340 for moving along the X-axis, the second guide assembly 330 includes a second slide rail 331 and a second slide 332, the second slide rail 331 and the second slide 332 are slidably connected, the base 130 is fixed on the second slide 332, the third guide assembly 340 includes a third slide rail 341 and a third slide 342, the third slide rail 341 is fixed on the workbench 110, the third slide rail 341 and the third slide 342 are slidably connected, and the second slide rail 331 is fixed on the third slide 342.

[0046] In this way, the third slide 342 moves along the third rail 341 in the X-axis direction, driving the second rail 331 to move; the second slide 332 moves along the second rail 331 in the Y-axis direction, driving the cradle device 310 to move; the cradle seat 312 rotates around the Y-axis on the fixed frame 311, and the rotating device 320 rotates around the Z-axis on the cradle seat 312, and the processing seat 321 rotates accordingly, thereby adjusting the position and angle of the workpiece in multiple dimensions. Thus, using two guide rails to achieve movement in the X and Y axes, and two rotating structures to achieve rotation around the Y and Z axes, the requirements of five-axis machining for multi-angle and multi-position machining of workpieces are met, and the ability to machine complex curved surfaces is improved.

[0047] If the debris cannot fall smoothly into the drainage trough, it will affect the subsequent solid-liquid separation and waste disposal process, and increase the workload and difficulty of manual cleaning. Therefore, in some embodiments, a flushing assembly is further included, wherein the flushing assembly includes a booster pump and multiple flushing heads, and the multiple flushing heads are fixed to the top of the workbench. The water outlet of the booster pump is connected to the multiple flushing heads, and the water inlet of the booster pump is connected to the drainage trough.

[0048] While the machine tool is operating, a booster pump draws coolant from the drain tank. After being pressurized, the high-pressure coolant is delivered through pipes to multiple flushing heads on top of the worktable. These flushing heads spray coolant onto the machining area at a specific angle and pressure, providing a comprehensive rinse of the workpiece surface and tool. The impact of the water flow quickly disperses metal chips adhering to the workpiece and tool, freeing them from the machined surface. These chips then flow along with the flushing fluid to the worktable's waste outlet, ultimately falling into the drain tank. This ensures that the chips remain within the tank, facilitates subsequent separation of the solid-liquid mixture by the collection mechanism, and further improves the overall chip collection and removal efficiency of the machine tool.
