Description

Technical Field

[0001] This application relates to the field of CNC machining equipment technology, and in particular to a machine tool cleaning system and its working method. Background Technology

[0002] Multi-spindle machining has become a trend in batch machining. Currently, machining centers with automatic tool changers mainly use two types of cleaning solutions for spindle taper holes and tool holder taper surfaces: one is compressed air blowing, which uses the machine tool's air source to spray dust off the taper surface during tool changing; the other is mechanical brush cleaning, which uses brushes to wipe the taper surface.

[0003] However, the cleaning effect of compressed air and brushes is limited, and they are prone to secondary pollution such as brush bristle shedding. Furthermore, the existing cleaning actions are not well matched with the machine tool tool change sequence, and the cleaning time needs to occupy the processing cycle, resulting in low equipment efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a machine tool cleaning system and its working method to solve the problems existing in related technologies. The technical solution is as follows: In a first aspect, embodiments of this application provide a machine tool cleaning system, comprising: a water supply module for providing power to the overall water circuit; a water storage module connected to the water supply module for storing cleaning water and pre-pressurizing it; a first water outlet module connected to the water supply module to form a first cleaning pipeline for providing workpiece cooling and machine bed cleaning; and a second water outlet module connected to the water storage module to form a second cleaning pipeline for cleaning the spindle taper hole and the tool holder taper surface; wherein a first two-way valve is provided at the connection between the water supply module and the water storage module for controlling the on / off state of the water storage pipeline; a second two-way valve is provided at the connection between the water storage module and the second water outlet module for controlling the on / off state of the second cleaning pipeline; and a third two-way valve is provided at the connection between the water supply module and the first water outlet module for controlling the on / off state of the first cleaning pipeline.

[0005] In one embodiment, the water supply module includes a water pump connected to an external clean water source and a first overflow valve disposed at the outlet of the water pump; the output end of the water pump is connected to the water storage module and the first water outlet module respectively.

[0006] In one embodiment, the water storage module includes a water storage tank and a three-position five-way solenoid valve disposed on the water storage tank. The three-position five-way solenoid valve is used to control the air intake, pressure holding and air exhaust of the water storage tank. The input end of the water storage tank is connected to the output end of the water pump, and the output end of the water storage tank is connected to the second water outlet module.

[0007] In one embodiment, a level gauge is installed inside the water storage tank, and a second overflow valve is installed at the connection between the water storage tank and the three-position five-way solenoid valve to relieve pressure in the water storage tank that exceeds a preset value.

[0008] In one embodiment, a throttle valve, an inlet filter, and a check valve are provided at the connection between the water storage tank and the water pump; the throttle valve, the inlet filter, and the check valve are arranged sequentially along the water flow output direction of the pipeline, and the throttle valve is located downstream of the first two-way valve.

[0009] In one embodiment, the second two-way valve is connected to the water storage tank through a large-diameter pipeline, and the second two-way valve is located close to the second water outlet module.

[0010] Secondly, embodiments of this application provide a method for operating a cleaning system, comprising the following steps: S1: After the system starts, the water level in the storage tank is detected. When the water level in the storage tank reaches the standard, the water storage module enters the pre-pressurization state. S2: Compressed air is introduced into the water storage tank. After the preset pressurization time is reached, pressurization is stopped and pressure is maintained. The water storage module enters the pressure maintenance state. S3: When the machine tool triggers the tool change action, the system starts within the preset time window. The water storage module enables the second water outlet module to perform high-pressure rinsing on the spindle taper hole and the tool holder taper surface. After rinsing, the process is repeated to the water storage stage, and then the next cleaning cycle begins.

[0011] In one embodiment, the detection of the water level in the storage tank includes: detecting the water level in the storage tank using a level gauge; if the water level in the storage tank is detected to be higher than a preset value, the system directly enters a pre-pressurization state; if the water level in the storage tank is detected to be lower than the preset value, the water supply module replenishes water to the storage tank until the storage tank is full, and then the system enters a pre-pressurization state.

[0012] In one embodiment, starting the system within a preset time window means starting the system within the time window from when the machine tool releases the tool to when it is loaded.

[0013] In one implementation, the water supply module operates selectively according to the system's water demand, and the opening and closing of the first cleaning pipeline is controlled by a third two-way valve.

[0014] The advantages or beneficial effects of the above technical solutions include at least the following: The machine tool cleaning system of this application can achieve parallel control of dual water paths through the on / off switching of different valve bodies, meeting the differentiated water pressure and flow requirements of different parts of the machine tool. Moreover, the cleaning efficiency of water flushing is superior to air blowing and brushing, eliminating the risk of secondary pollution such as brush bristle shedding, and ensuring safe use. At the same time, this cleaning system can be fully integrated into the original automatic tool changing process of the machine tool without occupying additional standby time, achieving zero cycle time loss in system cleaning and improving equipment working efficiency.

[0019] In the following description, only certain exemplary embodiments are briefly described to make the objects, features, and advantages of the present invention more apparent. As will be appreciated by those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1 like Figure 1As shown, this embodiment provides a machine tool cleaning system, including: a water supply module 1 for providing power to the overall water circuit; a water storage module 2 connected to the water supply module 1 for storing cleaning water and pre-pressurizing it; a first water outlet module 3 connected to the water supply module 1 to form a first cleaning pipeline for providing workpiece cooling and machine bed cleaning; and a second water outlet module 4 connected to the water storage module 2 to form a second cleaning pipeline for cleaning the spindle taper hole and tool holder taper surface. A first two-way valve 5 is provided at the connection between the water supply module 1 and the water storage module 2 to control the opening and closing of the water storage pipeline; a second two-way valve 6 is provided at the connection between the water storage module 2 and the second water outlet module 4 to control the opening and closing of the second cleaning pipeline; and a third two-way valve 7 is provided at the connection between the water supply module 1 and the first water outlet module 3 to control the opening and closing of the first cleaning pipeline.

[0022] In some embodiments, the machine tool cleaning system mainly includes a water supply module 1, a water storage module 2, a first water outlet module 3, and a second water outlet module 4. The water supply module 1 reuses the machine tool's original water pump 8, providing power to the overall water circuit of the system. The water outlet of the water supply module 1 is connected to the first water outlet module 3 and the water storage module 2, respectively, enabling the water supply module 1 to supply water to both the first water outlet module 3 and the water storage module 2. The first water outlet module 3 is used for workpiece cooling and bed cleaning (low-pressure rinsing), while the second water outlet module 4 is used for cleaning the spindle taper hole and tool holder taper surface (high-pressure rinsing). This configuration enables the machine tool system to achieve parallel control of dual water circuits, meeting the differentiated water pressure and flow requirements of different parts of the machine tool. Furthermore, the cleaning efficiency through water rinsing is superior to air blowing and brushing, eliminating the risk of secondary pollution such as brush bristle shedding, and ensuring safe operation.

[0023] The input end of the first water outlet module 3 is connected to the water supply module 1, and the two form a first cleaning pipeline. The first water outlet module 3 can provide workpiece cooling and bed cleaning effects for the machine tool cleaning system through the water supplied by the water supply module 1. The water storage module 2 can store the cleaning water input by the water supply module 1 and achieve pre-pressurization. The output end of the water storage module 2 is connected to the second water outlet module 4. The water storage module 2 can provide pressurized water to the second water outlet module 4, so that the second water outlet module 4 can release high-pressure water during the cleaning process. The input end of the second water outlet module 4 is connected to the water storage module 2, and the two form a second cleaning pipeline. The second water outlet module 4 can provide spindle taper hole and tool holder taper surface cleaning effects for the machine tool system through the pressurized water supplied by the water storage module 2.

[0024] The first two-way valve 5 is located between the water supply module 1 and the water storage module 2, and can control the on / off state of the water storage pipeline; the second two-way valve 6 is located between the water storage module 2 and the second water outlet module 4, and can control the on / off state of the high-pressure water spray pipeline; the third two-way valve 7 is located between the water supply module 1 and the first water outlet module 3, and can control the on / off state of the machine bed cleaning pipeline; the above-mentioned first two-way valve 5, second two-way valve 6 and third two-way valve 7 are all two-position two-way valves. The two-position two-way valve has a simple structure, high reliability and fast response speed, and is simple and convenient to control; the system independently controls the on / off state of each different functional pipeline through three two-position two-way valves, avoiding mutual interference between pipelines, improving system controllability and safety, and improving the working efficiency of the machine tool.

[0025] Furthermore, the water supply module 1 includes a water pump 8 connected to an external clean water source and a first overflow valve 9 disposed at the outlet of the water pump 8; the output end of the water pump 8 is connected to the water storage module 2 and the first water outlet module 3 respectively.

[0026] In some embodiments, the water supply module 1 includes a water pump 8 and a first overflow valve 9. The water pump 8 is connected to an external clean water source and can provide stable hydraulic power to the overall water circuit of the system. The outlet of the water pump 8 is equipped with the first overflow valve 9 as a bypass valve, which can effectively prevent the water pump 8 from being damaged due to insufficient system flow and improve the reliability of system operation. The output end of the water pump 8 is connected to the water storage module 2 and the first water outlet module 3 respectively, so that the water supply module 1 can supply water to the water storage module 2 and the first water outlet module 3 respectively, realizing one pump for multiple uses. The water storage module 2 does not need to be equipped with an additional independent power source, reducing system cost and space occupation.

[0027] Furthermore, the water storage module 2 includes a water storage tank 10 and a three-position five-way solenoid valve 11 disposed on the water storage tank 10. The three-position five-way solenoid valve 11 is used to control the air intake, pressure holding and air exhaust of the water storage tank 10. The input end of the water storage tank 10 is connected to the output end of the water pump 8, and the output end of the water storage tank 10 is connected to the second water outlet module 4.

[0028] In some embodiments, the water storage module 2 includes a water storage tank 10 and a three-position five-way solenoid valve 11. The water storage tank 10 can receive water input from the water pump 8 and store cleaning water. The three-position five-way solenoid valve 11 can control the air intake, pressure holding, and air exhaust of the water storage tank 10 to achieve multi-state control and pre-pressurization effect of the water storage tank 10 (air intake can pressurize the water in the water storage tank 10 to obtain high pressure energy, pressure holding can maintain the pressure in the water storage tank 10 to be stable for use at any time, and air exhaust facilitates the provision of a water flow environment for the water storage tank 10 during the water storage stage, ensuring that water storage and air exhaust occur simultaneously in the water storage tank 10, preventing the water source from being unable to enter the water storage tank 10). The output end of the water storage tank 10 is connected to the second water outlet module 4, which can provide pressurized water to the second water outlet module 4, enabling the second water outlet module 4 to release high-pressure water during the cleaning process without the need for an additional high-pressure pump, reducing system cost and space occupation.

[0029] Furthermore, a level gauge is installed inside the water storage tank 10, and a second overflow valve 12 is installed at the connection between the water storage tank 10 and the three-position five-way solenoid valve 11, for relieving the pressure of the water storage tank 10 that exceeds the preset value.

[0030] In some embodiments, a level gauge is installed inside the water storage tank 10. The level gauge can monitor the water volume in the water storage tank 10 in real time and can convert the full water state or the water shortage state of the water storage tank 10 into a corresponding electrical signal to assist in the automatic water replenishment control of the water storage tank 10. A second overflow valve 12 is installed on the water storage tank 10. The second overflow valve 12 serves as a secondary safety protection component and can relieve the pressure generated by the water storage tank 10 exceeding the set value, thereby achieving the automatic pressure relief effect of the water storage module 2 and improving the safety performance of the system.

[0031] Furthermore, a throttle valve 13, an inlet filter 14, and a one-way valve 15 are provided at the connection between the water storage tank 10 and the water pump 8; the throttle valve 13, the inlet filter 14, and the one-way valve 15 are arranged sequentially along the water flow output direction of the pipeline, and the throttle valve 13 is located downstream of the first two-way valve 5.

[0032] In some embodiments, the throttle valve 13, the inlet filter 14, and the check valve 15 are sequentially arranged between the connection between the water storage tank 10 and the water pump 8 along the water flow output direction of the pipeline. Specifically: the throttle valve 13 is located downstream of the first two-way valve 5 and can adjust the inlet flow of the water storage module 2 to adapt to different water source pressures, reduce the interference of the water storage process on the workpiece cooling path, and ensure the stability of the water output; the check valve 15 is located at the inlet of the water storage tank 10 and can ensure that the water flow in the water path is unidirectional and prevent water backflow when compressed air is pressurized; the inlet filter 14 is located between the throttle valve 13 and the check valve 15 and can intercept impurities, perform pre-filtration and purification of the cleaning water entering the water storage tank 10, and maintain the stable operation of the cleaning system.

[0033] Furthermore, the second two-way valve 6 is connected to the water storage tank 10 through a large-diameter pipeline, and the second two-way valve 6 is located close to the second water outlet module 4.

[0034] In some embodiments, the second two-way valve 6 is connected to the water storage tank 10 through a large-diameter pipeline. Using a large-diameter pipeline can reduce fluid resistance and ensure sufficient water flow in the second water outlet module 4. The installation position of the second two-way valve 6 is as close as possible to the nozzle of the second water outlet module 4. By shortening the distance for high-pressure water to reach the nozzle, the water spray response speed of the second water outlet module 4 can be guaranteed, the response delay can be reduced, and the flushing timing during the blade changing window time can be more accurate and the pressure more stable.

[0035] Example 2 like Figure 2 As shown, this embodiment provides a cleaning system operation method, applied to the machine tool cleaning system described in Embodiment 1, including the following steps: S1 Water Storage Stage: After the system starts up, the water level of water storage tank 10 is detected. When the water level of water storage tank 10 reaches the standard, water storage module 2 enters the pre-pressurization state. S2 Pre-pressurization stage: Compressed air is introduced into the water storage tank 10. After the preset pressurization time is reached, pressurization is stopped and pressure is maintained. The water storage module 2 enters the pressure maintenance state. S3 Tool Changing and Cleaning Stage: When the machine tool triggers the tool changing action, the system starts within the preset time window. The second water outlet module 4 performs high-pressure rinsing on the spindle taper hole and the tool holder taper surface through the water storage module 2. After rinsing, the process is repeated to the water storage stage, and the next cleaning cycle begins.

[0036] In some embodiments, the machine tool cleaning system of this application provides a cyclic working mode of "water storage → pre-pressurization → pressure holding → tool change cleaning → instant water spraying". After the system is started, during the water storage stage, the level gauge in the water storage tank 10 detects the water level in the water storage tank 10. If the water storage tank 10 is short of water, water is added. When the water level in the water storage tank 10 reaches the standard, the water storage tank 10 directly enters the pre-pressurization state.

[0037] During the pre-pressurization stage, compressed gas is introduced into the water storage tank 10 through the three-position five-way solenoid valve 11. At this time, the first two-way valve 5 is closed, the three-position five-way solenoid valve 11 is switched to the air inlet position, and the second two-way valve 6 is closed. After the set pressurization time is reached, pressurization is stopped and pressure is maintained (the pressurization time depends on the actual water usage, and the volume of the water storage tank 10 and the water usage also need to be determined according to the actual needs). At this time, the three-position five-way solenoid valve 11 is switched to the middle seal position, and the water storage tank 10 is kept in a high-pressure ready-to-spray state. Pressure exceeding the set value is discharged by the second overflow valve 12.

[0038] During the tool change and cleaning phase, the machine tool triggers a tool change action and starts cleaning within a preset time window. At this time, the first two-way valve 5 is closed, the three-position five-way solenoid valve 11 is switched to the air inlet position, the second two-way valve 6 is opened, and high-pressure water is sprayed out from the outlet of the second water outlet module 4 to perform high-pressure rinsing on the spindle and tool holder conical surface. After the timed rinsing is completed (the timed rinsing time depends on the actual tool change time during equipment operation; the cleaning time range for some existing equipment models is 3s to 5s), the liquid level in the water tank 10 is re-detected, and water is replenished or pressurized to enter the next cleaning cycle.

[0039] Through automated timing control of the system, the cleaning action of the machine tool is used as a trigger signal, so that the cleaning action of the machine tool is completed within the tool change interval. There is no need to increase the machine tool standby time, and the processing cycle is not occupied. The equipment works more efficiently, and labor intensity and production costs are reduced.

[0040] Furthermore, the detection of the water level in the water storage tank 10 includes: detecting the water level in the water storage tank 10 using a level gauge; if the water level in the water storage tank 10 is detected to be higher than a preset value, the system directly enters the pre-pressurization state; if the water level in the water storage tank 10 is detected to be lower than the preset value, the water supply module 1 replenishes water to the water storage tank 10 until the water storage tank 10 is full, and then enters the pre-pressurization state.

[0041] In some embodiments, detecting the water level in the water tank 10 specifically includes the following judgment steps: when the level gauge detects that the water level in the water tank 10 is higher than the preset value, that is, the water tank 10 is not short of water or is full of water, it directly enters the pre-pressurization state; when the level gauge detects that the water level in the water tank 10 is lower than the preset value, that is, the water tank 10 is short of water, the water supply module 1 replenishes water to the water tank 10. At this time, the first two-way valve 5 opens, the three-position five-way solenoid valve 11 switches to the venting position, the second two-way valve 6 closes, and water is continuously replenished until the water tank 10 is full of water, and then it enters the pre-pressurization state; the above control logic ensures that the water tank 10 is in a full water pressurization state before each tool change and cleaning of the machine tool, ensuring the consistency of flushing pressure and water volume, and improving cleaning stability.

[0042] Furthermore, starting the system within the preset time window means starting the system within the time window from when the machine tool releases the tool to when it is loaded.

[0043] In some embodiments, the preset time window is configured to precisely utilize the only time period during the tool change process when the spindle taper hole is exposed and there is no tool obstruction within the time window from when the machine tool releases the tool to when it is loaded. This ensures thorough cleaning without damaging the tool, and does not occupy additional machine tool standby time. It is fully integrated into the original automatic tool change process of the machine tool, achieving zero cycle time loss for system cleaning.

[0044] Furthermore, based on the system's water demand, the water supply module 1 operates selectively and controls the opening and closing of the first cleaning pipeline through the third two-way valve 7.

[0045] In some embodiments, the two water outlets of the first water outlet module 3 and the second water outlet module 4 are in an "OR" logical relationship. When either the first water outlet module 3 or the second water outlet module 4 needs water, the water supply module 1 remains operational. When the first water outlet module 3 does not need water and the water storage module 2 needs to be replenished, the third two-way valve 7 is closed to reduce water consumption. When the first water outlet module 3 does not need water and the water storage module 2 does not need to be replenished, the water supply module 1 stops operating. By controlling the on / off state of different two-way valves, water circuits with different functions can be selectively operated, enabling the system to flexibly switch under different operating conditions, taking into account both cleaning needs and energy conservation and environmental protection.
