[0002] A machining center is a CNC machine tool that integrates multiple machining functions and features high precision, high efficiency, and high automation. When a machining center processes a workpiece, the friction between the tool and the workpiece generates a large amount of heat in the machining area. If the heat is not dissipated in time, the tool and the workpiece will be damaged, which will not only reduce the tool life, but also affect the machining accuracy and surface roughness of the workpiece. Therefore, coolant plays a vital role in a machining center. One of the main functions of coolant is to reduce the temperature of the machining area. It can reduce thermal damage to cutting tools and workpieces, and ensure machining efficiency and quality.

[0003] During the operation of the machining center, the faster the tool runs, the greater the amount of cutting per unit time, and the more heat is generated in the machining area. However, the current liquid supply device cannot automatically adjust the cooling effect of the coolant according to the amount of heat generated in the machining area. When the heat generated in the machining area is too much, it is easy to cause insufficient cooling and poor cooling effect.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 12 As shown, the technical solution adopted by the present invention is as follows: an intelligent constant pressure liquid supply device for a machining center includes a box body 1, a measuring unit, a collection box 16 and a cooling mechanism. A processing box 2 is arranged on the box body 1, and a fixed plate 3 is fixedly installed in the processing box 2, and the fixed plate 3 is used to support the workpiece to be processed. A manipulator body 6 is arranged on the box body 1, and a tool 4 is installed on the manipulator body 6, and the tool 4 processes the workpiece. The lower end of the processing box 2 is funnel-shaped, and a through hole 13 connected to the lower end of the processing box 2 is opened on the side wall of the box body 1.

[0023] A plurality of collecting boxes 16 are movably arranged in the box body 1, and a driving mechanism for driving the collecting boxes 16 to intermittently move is arranged in the box body 1. The metal scraps and coolant in the processing box 2 enter the collecting box 16 directly below the through hole 13 through the through hole 13.

[0024] The driving mechanism includes a first sprocket 14, a second sprocket 15 and a chain 22. A first rotating shaft 8 and a second rotating shaft 11 are rotatably arranged in the box body 1, and the first rotating shaft 8 and the second rotating shaft 11 are arranged in parallel. Two first sprockets 14 are coaxially fixedly installed on the first rotating shaft 8, and the two first sprockets 14 are spaced apart along the first rotating shaft 8. Two second sprockets 15 are coaxially fixedly installed on the second rotating shaft 11, and the two second sprockets 15 are spaced apart along the second rotating shaft 11. The first sprocket 14 and the second sprocket 15 correspond to each other one by one, and each first sprocket 14 and the corresponding second sprocket 15 are connected by a chain 22 for transmission. A plurality of connecting seats 28 are evenly fixedly installed on the chain 22, and the connecting seats 28 are fixedly connected to the collection box 16. The collection box 16 is fixedly installed between the two chains 22 through the connecting seat 28. The connecting seat 28 is connected to the middle part of the collection box 16.

[0025] The housing 1 is provided with a driving unit for driving the chain 22 to intermittently move. In this embodiment, the driving unit is a grooved wheel mechanism. Specifically, the driving unit includes a grooved wheel 33, a dial 36 and a motor 35. A connecting plate 34 is fixedly mounted on the side wall of the housing 1, and the motor 35 is fixedly mounted on the connecting plate 34. The grooved wheel 33 and the dial 36 are both rotatably mounted on the housing 1, and the dial 36 is fixedly connected to the motor shaft of the motor 35. One end of the first rotating shaft 8 extends outside the housing 1 and is fixedly connected to the grooved wheel 33. The dial 36 is connected to a connecting rod, and a cylindrical pin 37 is connected to the connecting rod. The grooved wheel 33 is provided with a notch 38 that cooperates with the cylindrical pin 37. The motor 35 drives the dial 36 to rotate, and the dial 36 drives the grooved wheel 33 to intermittently move, so that the first rotating shaft 8 rotates intermittently, and then the chain 22 moves intermittently.

[0026] The collecting box 16 is open, and a drain port is provided at the lower end of the collecting box 16. A filter screen 17 is provided in the collecting box 16 to slide up and down, and the filter screen 17 filters the metal debris. Specifically, a chute 21 is provided on the box body 1, and the filter screen 17 is fixedly connected to a connecting block that is slidably provided in the chute 21. In order to allow the metal debris that enters the chute 21 to slide out smoothly, an inclined surface is provided on the inner wall of one side of the chute 21 near the upper end.

[0027] The measuring unit is arranged in the box 1 and is used to measure the amount of metal debris on the filter 17. The measuring unit includes a pressure sensor 26 and a slider 25. A fixing frame 18 is fixedly arranged in the box 1, a mounting block 27 is fixedly connected to the fixing frame 18, and the pressure sensor 26 is mounted on the mounting block 27. The slider 25 is fixedly connected to the connecting block, the box 1 is fixedly connected to the fixing block 23, and a first spring 24 is fixedly connected between the fixing block 23 and the slider 25. Initially, above the chain 22, the connecting block is at the lower end of the slide 21. As the collection box 16 moves, when the slider 25 contacts the pressure sensor 26, the slider 25 gradually moves up and moves to the pressure sensor 26, and the pressure sensor 26 is squeezed by the slider 25. The lower end of the slider 25 is arranged in an arc shape. Since the gravity of the filter 17 is constant, and when the slider 25 is on the pressure sensor 26, the deformation of the first spring 24 is constant. Therefore, the more metal debris on the filter 17, the greater the measured value of the pressure sensor 26.

[0028] The cooling mechanism includes a condenser 9 and a water pump 12. The water pump 12 is installed on the box body 1, and the water outlet of the water pump 12 is connected to the coolant nozzle 5 through a hose, and the coolant nozzle 5 is arranged in cooperation with the tool 4. The water inlet of the water pump 12 is connected to a liquid supply pipe 39, and the liquid supply pipe 39 is connected to the output end of the condenser 9. The input end of the condenser 9 is connected to a return pipe 10. A liquid outlet 29 is provided on the water tank 19, and the return pipe 10 is connected to the liquid outlet 29. The coolant in the water tank 19 enters the condenser 9 through the return pipe 10, and after the cooling treatment of the condenser 9, it flows to the coolant nozzle 5 through the liquid supply pipe 39 and the water pump 12 in sequence.

[0029] The condenser 9 and the pressure sensor 26 are both electrically connected to the controller. The pressure sensor 26 transmits the pressure value to the controller, and the controller adjusts the power of the condenser 9 according to the pressure value of the pressure sensor 26, and then adjusts the temperature of the coolant output by the condenser 9. The pressure value is divided into multiple pressure intervals, and each pressure interval corresponds to a temperature value, that is, the controller will judge the received measurement value to see which pressure interval the measurement value falls into, and then adjust the condenser 9 accordingly, so that the condenser 9 outputs the coolant of the corresponding temperature. The power of the water pump 12 is constant, that is, the liquid output of the coolant nozzle 5 is unchanged. The lower the temperature of the coolant sprayed by the coolant nozzle 5, the better the cooling effect.

[0030] The greater the amount of cutting by the tool 4 per unit time, the more metal debris is generated, the greater the heat generated per unit time, the more metal debris enters the collection box 16, and the greater the value of the pressure interval where the measured value of the pressure sensor 26 is located, the lower the temperature of the coolant flowing out of the condenser 9, and thus the processing area is better cooled to ensure the cooling effect. By measuring the amount of metal debris generated, the power of the condenser 9 is adjusted, and the temperature of the coolant flowing out of the condenser 9 is adapted to the amount of cutting by the tool 4, which is beneficial to ensure the processing quality and save energy.

[0031] The fixing frame 18 is provided with a liquid inlet 20 that matches the liquid discharge port. The lower end surface of the collecting box 16 is sealed and slidably matched with the upper end surface of the fixing frame 18. The upper end surface of the fixing frame 18 has a blocking effect on the liquid discharge port of the collecting box 16. When the liquid discharge port is connected to the liquid inlet 20, the coolant in the collecting box 16 flows out through the liquid discharge port.

[0032] A water tank 19 is elastically slidably arranged up and down in the fixing frame 18, and the coolant in the collecting box 16 flows into the dynamic water tank 19 through the liquid inlet 20. A second spring 31 is fixedly connected between the lower end of the water tank 19 and the fixing frame 18. A knocking rod 30 is fixedly arranged at the lower end of the water tank 19.

[0033] As the chain 22 moves, when the collection box 16 gradually moves to the lower side of the chain 22, the metal scraps in the collection box 16 gradually fall out. A collection box 7 is slidably arranged in the box body 1, and the collection box 7 collects the metal scraps.

[0034] When the collecting box 16 is at the lower side of the chain 22 and below the knocking rod 30, when the coolant in the collecting box 16 enters the water tank 19 through the liquid inlet 20, under the impact of the coolant and the action of the second spring 31, the water tank 19 vibrates up and down, the knocking rod 30 vibrates up and down, and the knocking rod 30 pushes the slider 25 to move, thereby causing the filter 17 to vibrate up and down in the collecting box 16, which is beneficial to shake off the metal debris remaining on the filter 17 and has a cleaning effect on the filter 17.

[0035] A guide block 32 is provided in the water tank 19 , and the liquid outlet 29 corresponds to the lower end of the guide block 32 , so that the coolant in the water tank 19 converges at the liquid outlet 29 .

[0036] Working principle: On the upper side of the chain 22, the position directly below the through hole 13 is named the collection station, and the position corresponding to the liquid inlet 20 is named the discharge station. Figure 2As shown, among the multiple collection boxes 16 on the upper side of the chain 22, the upper ends of two adjacent collection boxes 16 are in contact with each other, one of the collection boxes 16 stays just below the through hole 13, that is, in the collection position, and one of the collection boxes 16 stays in the discharge position. The upper end surface of the fixing frame 18 seals the discharge port of the corresponding collection box 16. And initially, in the collection box 16 on the upper side of the chain 22, the connecting block contacts the lower end of the chute 21.

[0037] When in use, the workpiece is mounted on the fixing plate 3, the water pump 12, the condenser 9, and the manipulator body 6 are started, the condenser 9 cools the coolant to a certain temperature, the coolant is sprayed through the coolant nozzle 5 and cools the processing area. The tool 4 processes the workpiece, and the generated metal scraps and coolant enter the processing box 2 and fall into the corresponding collection box 16.

[0038] The motor 35 is started, and the dial 36 rotates. The dial 36 drives the groove wheel 33 to rotate intermittently through the cylindrical pin 37, and the first rotating shaft 8 rotates intermittently, so that the chain 22 moves intermittently, and then the collecting box 16 moves intermittently. That is, the collecting box 16 will stay at the corresponding station for a certain period of time and then move to the next station. On the upper side of the chain 22, when the collecting box 16 is at the collecting station, the metal chips and coolant in the processing box 2 will fall into the collecting box 16. The filter screen 17 separates the coolant and the metal chips, and the metal chips are retained on the filter screen 17.

[0039] Then, as the chain 22 moves intermittently, Figure 2 As shown, the collection box 16 moves to the left on the upper side of the chain 22. The next collection box 16 moves to the collection station, and the collection box 16 containing metal scraps moves to the left to the drainage station. The drainage port on the collection box at the drainage station is connected to the liquid inlet 20, and the coolant in the collection box 16 flows into the water tank 19 through the liquid inlet 20.

[0040] The coolant enters the water tank 19 , and under the action of the second spring 31 , the water tank 19 vibrates up and down, the knocking rod 30 vibrates up and down, the knocking rod 30 acts on the corresponding slider 25 , and the slider 25 drives the filter 17 to vibrate up and down, thereby shaking off the metal debris remaining on the filter 17 , which has a cleaning effect on the filter 17 .

[0041] When the collecting box 16 moves to the left, when the slider 25 moves toward the pressure sensor 26, the slider 25 moves up, causing the filter 17 to move up. At this time, the pressure sensor 26 supports the slider 25 and the filter 17 with the metal debris on the filter 17. The slider 25 squeezes the pressure sensor 26, and the pressure sensor 26 transmits the measured value to the controller. The controller adjusts the condenser 9 according to the pressure range of the measured value, so that the condenser 9 outputs the coolant of the corresponding temperature.

[0042] As the chain 22 moves, when the collection box 16 moves from the upper side of the chain 22 to the lower side of the chain 22, the metal debris in the collection box 16 falls into the collection box 7. On the lower side of the chain 22, the collection box 16 gradually moves to the right, and when the slider 25 on the collection box 16 cooperates with the knock rod 30, the knock rod 30 vibrates up and down, which drives the slider 25 to vibrate up and down, causing the filter 17 to vibrate up and down, and shaking off the metal debris remaining on the filter 17.

[0043] In this embodiment, the knocking rod 30 can cooperate with the sliders 25 on the three collection boxes 16 at the same time. That is, at the lower side of the chain 22, when the collection box 16 moves to the right, the slider 25 on the collection box 16 goes from being in contact with the knocking rod 30 to being separated from the knocking rod 30, and the slider 25 can be acted on by the knocking rod 30 three times, which is conducive to better cleaning of the filter 17.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
