Description

Technical Field

[0001] This invention relates to the field of CNC lathes, and in particular to a high-precision CNC lathe with intelligent chip removal function and its control method. Background Technology

[0002] A high-precision CNC lathe is a turning-milling composite machine tool. By adding a milling spindle, power head, and Y-axis, and equipped with a multi-axis linkage system, high-rigidity structure and tool magazine, it can complete multiple machining processes such as turning, milling, drilling and tapping in one setup. Its precision is comparable to that of a four-axis milling machine. At the same time, during the machining process, it realizes intelligent spray cooling and cutting fluid circulation through a built-in cutting fluid system.

[0003] However, in actual machining, CNC lathes usually do not have automatic feeding and replenishment functions. This means that during the machining process, when a machining operation or a workpiece is completed, the workpiece needs to be unloaded or loaded. At this time, the cutting fluid system stops with the machining program and restarts after a new workpiece is replaced. This requires the vortex separator and paper tape filter in the cutting fluid system to be frequently started and stopped. Otherwise, the liquid level in the wastewater tank will be too low, causing the industrial pump and vortex separator to run dry, and the clean water tank may burst. Frequent start and stop can also cause equipment damage and fluctuations in the cutting fluid filtration quality. Therefore, a high-precision CNC lathe with intelligent chip removal function and its control method are provided. Summary of the Invention

[0004] The purpose of this invention is to provide a high-precision CNC lathe with intelligent chip removal function and its control method, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision CNC lathe with intelligent chip removal function, comprising: Lathe body; A turning unit, comprising a spindle and a moving tool turret mounted in the lathe body; The cutting fluid circulation unit includes a cutting fluid nozzle, a slag interception tank, a wastewater tank, a clean water tank, a vortex separator, and a paper tape filter; The cutting fluid nozzle is mounted on the moving tool turret and is connected to the clean water tank; The slag interception box is located at the bottom of the lathe body; The wastewater tank and the clean water tank are arranged side by side inside one side of the lathe body, and the wastewater tank is connected to the slag interception tank by an overflow method; A liquid supply pump, a throttling solenoid valve, and a pressure gauge are installed between the input end of the vortex separator and the sewage tank. A water level sensor is installed in the sewage tank. The liquid supply pump automatically adjusts its frequency according to the feedback signal from the water level sensor. The throttling solenoid valve actively adjusts the flow rate according to the output power of the liquid supply pump so that the pressure gauge value is within a preset range. The paper tape filter is installed between the output end of the vortex separator and the clean water tank. The paper tape filter is equipped with a feed water drain with multiple rows of feed holes distributed in a stepped manner to ensure that the cutting fluid falls evenly into the paper tape filter.

[0006] Preferably, an industrial computer is fixedly installed on the lathe body, and the industrial computer is connected to the turning unit and the cutting fluid circulation unit for control. A tailstock facing the spindle is fixedly installed inside the lathe body.

[0007] Preferably, a guide plate is fixedly installed inside the lathe body and at the top of the slag interception box. A primary filter screen is fixedly installed inside the slag interception box. The primary filter screen divides the interior of the slag interception box into a slag area and a filtrate area. One end of the guide plate is tilted downwards and faces the slag area so that the cutting fluid enters the slag area and passes through the primary filter screen to block large particles of waste slag.

[0008] Preferably, a secondary filter screen is fixedly installed at one end of the slag area. The secondary filter screen is L-shaped and forms a fine material filtration area by the secondary filter screen and the side wall of the slag interception box. The two sides of the guide plate are inclined towards the middle to prevent cutting fluid from entering the fine material filtration area. A slag discharge pipe is fixedly installed at the bottom of the vortex separator. The other end of the slag discharge pipe is inclined downward and extends into the fine material filtration area.

[0009] Preferably, an overflow pipe is fixedly installed on one side of the filtrate zone, and an overflow inlet is provided on the side wall of the wastewater tank. The overflow pipe is movably inserted into the overflow inlet so that the cutting fluid after intercepting large particles of waste residue enters the wastewater tank.

[0010] Preferably, a water inlet pipe is installed between the output end of the vortex separator and the liquid supply pump, the throttling solenoid valve and the pressure gauge are both installed on the water inlet pipe, a drain pipe is installed at the top of the vortex separator, and the other end of the drain pipe is connected to the feed water drain.

[0011] Preferably, an inclined guide plate is fixedly installed inside the paper tape filter. A feed roller and a take-up roller are rotatably arranged at both ends of the inclined guide plate. Filter paper is wound between the feed roller and the take-up roller. The filter paper is attached to the top of the inclined guide plate. A water inlet hole for connecting to the clean water tank is opened at the bottom of the paper tape filter. A servo motor for driving the take-up roller to rotate is fixedly installed on one side of the paper tape filter.

[0012] Preferably, the inclined guide plate has two sides that slope towards the center to naturally form a guide portion, so that the filter paper laid on the inclined guide plate naturally forms a filter area in the center. The feed hole is directly opposite the filter area, and the inclined guide plate is provided with multiple permeable grids so that the filter area naturally forms a concave position for intercepting filter residue, so as to prevent the filter residue from sliding down and accumulating.

[0013] Preferably, the interior of the clean water tank is equipped with an ultrasonic defoamer and a heat exchange tube, the outer wall of the lathe body is equipped with a circulating chiller connected to the heat exchange tube, and a jet pump is installed between the clean water tank and the cutting fluid nozzle.

[0014] A control method for a high-precision CNC lathe with intelligent chip removal function includes the following steps: S1. The water level sensor monitors the water level in the sewage tank and adjusts the real-time power of the liquid supply pump by designing water level thresholds Hmax and Hmin. S2. The opening degree of the throttling solenoid valve is matched according to the power of the liquid supply pump to ensure that the pressure value on the pressure gauge is within the preset range. S3. The paper tape filter adjusts the paper tape winding speed according to the flow rate of the throttling solenoid valve to ensure effective utilization of the paper tape. The technical effects and advantages of this invention are as follows: 1. The control method of this high-precision CNC lathe with intelligent chip removal function determines the current cutting action by detecting the water level in the wastewater tank. When the water level in the wastewater tank rises rapidly, the output power of the liquid supply pump is increased. As the output power of the liquid supply pump increases, the opening of the throttling solenoid valve is automatically matched, so that the pressure gauge display is within the preset range. This achieves "constant pressure variable flow" control of the vortex separator, ensuring separation effect and equipment safety. As the cutting fluid return flow increases, the paper feed speed of the paper tape filter is actively adjusted to avoid waste caused by excessive paper movement speed and blockage caused by excessively slow paper movement. This rational and efficient use of filter paper enables the entire cutting fluid system to self-adaptively adjust, ensuring the supply of cutting fluid and the stable and continuous operation of all equipment in the entire cutting fluid system, avoiding the negative impact of downtime.

[0015] 2. This high-precision CNC lathe with intelligent chip removal function improves the design of the paper tape filter. When the feed flow rate of the vortex separator increases, the discharge flow rate also increases. At this time, the water level inside the feed water drain rises, and multiple rows of water inlets arranged in a stepped pattern inside the filter allow multiple rows of water to enter the paper tape filter in parallel. At the same time, the inclined guide plate inside the paper tape filter guides the cutting fluid to accurately pass through the filter paper, so that the filter paper can be effectively utilized and avoids the large unused areas on both sides of the filter paper caused by concentrated water discharge in the middle.

[0016] 3. This high-precision CNC lathe with intelligent chip removal function, through the design of a guide plate and a slag interception box, concentrates the slag into the slag zone under the action of the guide plate. Then, after the cutting fluid passes through the primary filter screen to intercept large particles of impurities, it enters the filtrate zone. The slag and part of the cutting fluid separated by the vortex separator are discharged through the bottom of the vortex separator and enter the fine material filtration zone through the slag discharge pipe. The secondary filter screen intercepts small particles of waste slag. The cutting fluid continues to pass through the secondary filter screen and the primary filter screen to enter the filtrate zone for return, realizing unified collection of slag and facilitating subsequent slag discharge treatment.

The liquid supply pump 133 automatically changes frequency according to the feedback signal from the water level sensor 18; the throttling solenoid valve 134 changes frequency according to the liquid supply pump 133. The output power of the 33 actively adjusts the flow rate so that the pressure gauge 135 value is within the preset range; the paper tape filter 14 is installed between the output end of the vortex separator 13 and the clean water tank 11. The paper tape filter 14 is provided with a feed water drain 146, and the feed water drain 146 has multiple rows of feed holes 1462 distributed in a stepped manner so that the cutting fluid falls evenly into the paper tape filter 14. The paper tape filter 14 adaptively adjusts the paper winding speed according to the flow rate of the throttling solenoid valve 134 to ensure effective utilization of the paper tape.

[0023] Inside the lathe body 1 and at the top of the slag interception box 8, a guide plate 5 is fixedly installed. Inside the slag interception box 8, a primary filter screen 82 is fixedly installed. The primary filter screen 82 divides the inside of the slag interception box 8 into a slag zone 84 and a filtrate zone 86. One end of the guide plate 5 is tilted downwards and faces the slag zone 84 so that after the cutting fluid enters the slag zone 84, it passes through the primary filter screen 82 to block large particles of waste slag.

[0024] A secondary filter screen 83 is fixedly installed at one end of the slag area 84. The secondary filter screen 83 is L-shaped. The secondary filter screen 83 and the side wall of the slag interception box 8 enclose the fine material filtration area 85. The two sides of the guide plate 5 are inclined towards the middle to prevent the cutting fluid on the guide plate 5 from entering the fine material filtration area 85.

An overflow inlet 12 is opened on the side wall of the sewage tank 10.

[0025] A water inlet pipe 132 is installed between the output end of the vortex separator 13 and the liquid supply pump 133. The throttling solenoid valve 134 and the pressure gauge 135 are both installed on the water inlet pipe 132. A drain pipe 137 is installed at the top of the vortex separator 13, and the other end of the drain pipe 137 is connected to the feed water drain 146.

[0026] An inclined guide plate 148 is fixedly installed inside the paper tape filter 14. A feed roller 142 and a take-up roller 143 are rotatably installed at both ends of the inclined guide plate 148. Filter paper 145 is wound between the feed roller 142 and the take-up roller 143. The filter paper 145 is attached to the top of the inclined guide plate 148. A water inlet hole 147 for connecting to the clean water tank 11 is opened at the bottom of the paper tape filter 14. A servo motor 144 for driving the take-up roller 143 to rotate is fixedly installed on one side of the paper tape filter 14. The two sides of the inclined guide plate 148 are inclined towards the middle to naturally form a guide section 1482, so that the middle of the filter paper 145 laid on the inclined guide plate 148 naturally forms a filtration area. The feed hole 1462 is directly opposite the filtration area. Multiple water-permeable grids 1483 are opened on the inclined guide plate 148 so that the filtration area naturally forms a concave position for intercepting filter residue, so as to prevent the filter residue from sliding down and accumulating.

[0027] Working principle: When in use, the device mounts the workpiece on the spindle 2, which drives the workpiece to rotate. At the same time, the moving tool turret 3 automatically switches the cutting head and realizes X, Y, and Z axis movement as well as rotation around the spindle 2, thereby achieving multi-angle ultra-high precision machining control. During the machining process, the jet pump 16 pumps the cutting fluid, which has been defoamed and cooled, from the clean water tank 11 into the cutting fluid nozzle 6, achieving precise spraying of the machining position and cooling of the workpiece and the cutting head. During the cutting process, metal chips are formed and drip onto the guide plate 5 with the cutting fluid. Then, under the action of the guide plate 5, they are concentrated and enter the slag zone 84. After the cutting fluid passes through the primary filter screen 82 to intercept large particles of impurities, it enters the filtrate zone 86. As the water level in the filtrate zone 86 rises above the overflow pipe 87, the cutting fluid enters the wastewater tank 10 through the overflow pipe 87. When the water level inside the wastewater tank 10 exceeds the bottom water level sensor 18, the water level sensor 18 sends a signal to the industrial computer 4. When the water level reaches above Hmin, the liquid supply pump 133 starts at a low frequency, and the throttling solenoid valve 134 is at its minimum opening, so that the cutting fluid enters the vortex separator 13 at a preset pressure. Small particles of solid material and part of the cutting fluid are discharged through the bottom of the vortex separator 13 and enter the fine material filtration zone 85 through the slag discharge pipe 136. The secondary filter screen 83 intercepts small particles of waste slag. The cutting fluid continues to pass through the secondary filter screen 83 and the primary filter screen 82 and enters the filtrate zone 86 for return. Meanwhile, during the above process, the clean cutting fluid separated by the vortex separator 13 enters the feed water drain 146 and is injected into the paper tape filter 14 through the feed hole 1462. After being filtered by the filter paper 145, the cutting fluid enters the clean water tank 11. Then, the cutting fluid is cooled by passing through the heat exchange tube 17 inside the clean water tank 11. After being defoamed by the ultrasonic defoamer 15, it is pumped into the cutting fluid nozzle 6 again by the jet pump 16 to achieve complete circulation of the cutting fluid. During the above process, as the water level inside the wastewater tank 10 rises, when the water level exceeds the water level sensor 18 at the top, the industrial computer 4 controls the liquid supply pump 133 to output at high frequency. At this time, the flow rate into the vortex separator 13 increases, and the throttling solenoid valve 134 increases its opening ratio to ensure that the pressure at the feed end of the vortex separator 13 is within the preset range, ensuring the separation effect and preventing damage to the vortex separator 13. When the feed flow rate of the vortex separator 13 increases, its discharge flow rate also increases. At this time, the water level inside the feed water drain 146 rises, and multiple rows of parallel water are fed into the paper tape through the stepped multi-row feed holes 1462 inside. The filter 14, along with the inclined guide plate 148 inside the paper tape filter 14, allows the cutting fluid to accurately pass through the filtration area of ​​the filter paper 145 via the guide part 1482. This ensures that the filter paper 145 can be effectively utilized, preventing concentrated water outflow in the middle and resulting in large unused areas on both sides of the filter paper 145. Furthermore, as the flow rate is adjusted by the throttling solenoid valve 134, the speed of the servo motor 144 changes, allowing the moving speed of the filter paper 145 to match the water flow rate. This prevents the filter paper 145 from having low utilization at low flow rates and from becoming clogged and overflowing to both sides at high flow rates, ensuring the efficient and stable use of the filter paper 145.

[0028] Finally, after the cutting operation is completed, the cutting fluid is recovered from the filtrate area 86 by pulling out the slag interception box 8, and then all the slag is poured out and the cutting fluid is injected back into the slag interception box 8, thereby achieving regular slag cleaning.

[0029] Example 2, as Figure 12 As shown, this embodiment provides a control method for a high-precision CNC lathe with intelligent chip removal function, including the following steps: S1, Water level sensor 18 monitors the water level of sewage tank 10, and adjusts the real-time power of liquid supply pump 133 by designing water level thresholds Hmax and Hmin; S2. The opening degree of the throttling solenoid valve 134 is matched according to the power of the liquid supply pump 133 to ensure that the pressure value of the pressure gauge 135 is within the preset range. S3. The paper tape filter 14 adjusts the paper tape winding speed according to the flow rate of the throttling solenoid valve 134 to ensure effective utilization of the paper tape.

[0030] Working principle: This method determines the current cutting action by detecting the water level in the wastewater tank 10. During continuous cutting or when the cutting rate increases, the amount of cutting fluid used increases, causing the water level inside the wastewater tank 10 to rise rapidly. At this time, the output power of the fluid supply pump 133 is increased to prevent the wastewater tank 10 from bursting. Simultaneously, the clean water tank 11 is supplied with sufficient clean cutting fluid to the cutting fluid nozzle 6. Furthermore, as the output power of the fluid supply pump 133 increases, the opening of the throttling solenoid valve 134 is automatically matched, thereby keeping the pressure gauge 135 digitally displayed within the preset range, thus realizing the vortex effect. The "constant pressure variable flow" control of separator 13 ensures separation effect and equipment safety. As the cutting fluid return flow increases, the paper feed speed of paper tape filter 14 is actively adjusted to avoid waste caused by excessive paper movement speed, and also to avoid blockage caused by excessive paper movement speed. The filter paper 145 is used rationally and efficiently to achieve adaptive adjustment of the entire cutting fluid system during CNC lathe cutting operations, machine stoppage unloading, and different cutting actions, ensuring the supply of cutting fluid and ensuring the stable and continuous operation of all equipment in the entire cutting fluid system, avoiding the negative impact of machine stoppage.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
