Description

Technical Field

[0001] This invention belongs to the field of thermal error compensation technology, specifically a method for thermal error compensation of CNC machine tools with non-metallic support components. Background Technology

[0002] Non-metallic support components refer to components used in mechanical equipment to support, fix, or isolate other parts. They are usually made of non-metallic materials, such as plastics, rubber, and ceramics. These materials have some properties that metals do not have, such as good heat insulation, corrosion resistance, and shock absorption, and can play an important role in specific engineering applications.

[0003] Thermal error refers to the error caused by changes in the size, shape, or properties of an object due to factors such as thermal expansion and heat conduction when the object is subjected to temperature changes. When an object expands or deforms due to heat, its size, shape, or properties may change, causing it to fail to meet accuracy requirements during use.

[0004] Thermal error compensation refers to using a series of technical means to reduce or offset errors caused by temperature changes, so as to ensure that equipment or systems can maintain the required accuracy and stability under different temperature conditions.

[0005] A search revealed a Chinese patent, CN108422208A, for an intelligent temperature rise compensation mineral casting machine bed. This bed is equipped with a mineral casting machine bed, lateral metal pipes, a central metal pipe, and temperature sensors. The mineral casting machine bed is a steel U-shaped frame filled with mineral material. Lateral metal pipes are embedded on both sides of the U-shaped frame, while the central metal pipe is located below the tool magazine mounting surface and the rotary table mounting surface, distributing outwards. The pipe interfaces of the two lateral metal pipes and the central metal pipe are connected to the inlet and outlet of an external water chiller, forming a three-way cooling circuit. Temperature sensors are located on both sides of the U-shaped frame, next to the tool magazine mounting surface and the rotary table mounting surface. The temperature sensors are connected to the machine tool control system, offering advantages such as low thermal shrinkage, intelligent monitoring and control, and high machine tool precision.

[0006] While current equipment can monitor machine tool temperature in real time using temperature sensors and reduce thermal errors through water cooling, the various processing methods and wide ranges of machine tools result in different rates of temperature rise during processing. In particular, prolonged or continuous processing can cause the machine tool temperature to rise rapidly, which increases the thermal error. Therefore, there is an urgent need for a thermal error compensation method for CNC machine tools with non-metallic support components. Summary of the Invention

[0007] The purpose of this invention is to provide a method for thermal error compensation of CNC machine tools with non-metallic support components, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a method for thermal error compensation of non-metallic support components in CNC machine tools, comprising the following steps:

[0009] S1: When the main body of the equipment is working, the temperature of the main body of the equipment is monitored in real time by a temperature sensor. When the temperature reaches a certain threshold, the pump, the first motor and the second motor are started by an external power source.

[0010] S2: The start of the pump causes the coolant to circulate in the cooling chamber and the delivery chamber, cooling the entire equipment body and thus compensating for thermal errors.

[0011] S3: The starting of the first motor drives the rotation of the threaded rod, the rotation of the threaded rod drives the movement of the first slider, and the movement of the first slider drives the movement of the first control board, so that the first control board opens the channel between the cooling chamber and the conveying chamber, making it easier for the coolant to enter the interior of the cooling chamber.

[0012] S4: At the same time, the movement of the first slider drives the movement of the first connecting plate, the movement of the first connecting plate drives the movement of the second slider, and the movement of the second slider drives the movement of the second control plate, so that the second control plate opens the channel on the other side of the cooling chamber and the conveying chamber, so that the coolant can flow out.

[0013] S5: At the same time, the movement of the first connecting plate drives the movement of the second connecting plate, the movement of the second connecting plate drives the movement of the third rotating shaft, and the movement of the third rotating shaft drives the movement of the tooth block, so that the tooth block is embedded in the tooth groove opened inside the first gear, the second gear or the third gear.

[0014] S6: The starting of the second motor drives the rotation of the seventh rotating shaft, the rotation of the seventh rotating shaft drives the rotation of the second protrusion, the rotation of the second protrusion drives the rotation of the third rotating shaft, the rotation of the third rotating shaft drives the rotation of the gear block, the rotation of the gear block drives the rotation of the first gear, the second gear or the third gear, the rotation of the first gear, the second gear or the third gear drives the rotation of the fourth gear, the fifth gear or the sixth gear, the rotation of the fourth gear, the fifth gear or the sixth gear drives the rotation of the fourth rotating shaft, the rotation of the fourth rotating shaft drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the push plate.

[0015] S7: Simultaneously, the rotation of the fourth rotating shaft drives the rotation of the fourth bevel gear, which in turn drives the rotation of the third bevel gear. The rotation of the third bevel gear drives the rotation of the sixth rotating shaft, which in turn drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear, which in turn drives the rotation of the fifth rotating shaft. The rotation of the fifth rotating shaft drives the movement of the fourth connecting plate, which, in conjunction with the spring, causes the fourth connecting plate to move up and down. The movement of the fourth connecting plate drives the movement of the third connecting plate, which in turn drives the movement of the first protrusion. This causes the first protrusion to strike the bottom of the filter box, ensuring the normal flow of coolant and thus ensuring stable thermal error compensation.

The inner walls of the first gear, the second gear, and the third gear are all provided with tooth grooves. A tooth block is embedded in the inner wall of one of the tooth grooves. The tooth block is fixedly installed on the outer wall of the third rotating shaft.

[0022] As a further technical solution of the present invention, a second connecting plate is fixedly installed on one side of the first connecting plate, and the end of the second connecting plate away from the first connecting plate is sleeved on the outer wall of the third rotating shaft.

[0023] As a further technical solution of the present invention, the number of teeth on the outer walls of the first gear, the second gear and the third gear increases sequentially, and the number of teeth on the outer walls of the fourth gear, the fifth gear and the sixth gear decreases sequentially.

[0024] As a further technical solution of the present invention, the filter assembly includes a filter box that is slidably installed on the inner wall of the device body.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention, through the setting of an auxiliary constant temperature component, allows the second motor to be started by an external power source when the temperature detected by the temperature sensor reaches a certain threshold. Since the input end of the second motor is electrically connected to the external power source via a wire, and the output end of the second motor is fixedly connected to the seventh rotating shaft, the start of the second motor can drive the rotation of the seventh rotating shaft. The rotation of the seventh rotating shaft drives the rotation of the second protrusion, which in turn drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the fourth rotating shaft via an adjustment component, which in turn drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the push plate, causing the push plate to rotate inside the cooling chamber, agitating the coolant, increasing the contact area between the coolant and the main body of the equipment, and improving the heat exchange efficiency. This allows for more effective absorption and release of heat, avoiding the problem of temperature rise rates due to the variety and range of machining methods on the machine tool. Especially during long-term or continuous machining, the machine tool temperature may rise rapidly, leading to increased thermal errors. Adjusting the temperature according to different machining methods not only improves the adaptability of the equipment but also reduces thermal errors during machining.

[0029] 2. This invention, through the configuration of the control components, allows the first motor to be started by an external power source when the temperature detected by the temperature sensor reaches a certain threshold. Since the input end of the first motor is electrically connected to the external power source via a wire, and the output end of the first motor is fixedly connected to a threaded rod, starting the first motor drives the rotation of the threaded rod. Because the threaded rod and the first slider are connected by internal and external threads, the rotation of the threaded rod drives the first slider to move, causing the first slider to move the first control plate, opening the channel between the cooling chamber and the conveying chamber, facilitating the entry of coolant into the cooling chamber. Simultaneously, the movement of the first slider drives the movement of the first connecting plate, which in turn drives the movement of the second slider, which in turn drives the movement of the second control plate, opening the channel between the cooling chamber and the other side of the conveying chamber, facilitating the outflow of coolant from the cooling chamber for exchange. The distance the first and second control plates move can be controlled by the PLC according to the temperature, thereby controlling the coolant flow rate to reduce thermal errors. Flow rate adjustment can be performed according to different processing methods, improving the adaptability of the device.

[0030] 3. By adjusting the component settings, when the first connecting plate moves, the movement of the first connecting plate drives the movement of the second connecting plate, which in turn drives the movement of the third rotating shaft. The movement of the third rotating shaft drives the movement of the toothed block, causing the toothed block to engage with the toothed grooves on the inner walls of the first, second, or third gear. The rotation of the third rotating shaft then drives the rotation of the toothed block, which in turn drives the rotation of the first, second, or third gear. The rotation of the first, second, or third gear then drives the rotation of the fourth, fifth, or sixth gear, which in turn drives the rotation of the fourth rotating shaft. The fourth rotating shaft provides power for the rotation of the auxiliary temperature control component, thus improving the adaptability of the equipment. Attached Figure Description

[0043] 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.

[0044] Example 1

[0045] like Figures 1 to 11As shown in the embodiment of the present invention, a method for thermal error compensation of a CNC machine tool with a non-metallic support component includes the following steps:

[0046] S1: When the main body of the equipment 1 is working, the temperature of the main body of the equipment 1 is monitored in real time by the temperature sensor 7. When the temperature reaches a certain threshold, the pump 6, the first motor 16 and the second motor 47 are started by the external power supply.

[0047] S2: The start of pump 6 causes the coolant to circulate in the cooling chamber 4 and the delivery chamber 5, cooling the entire main body 1 of the equipment and thus compensating for thermal errors.

[0048] S3: The start of the first motor 16 drives the rotation of the threaded rod 15, the rotation of the threaded rod 15 drives the movement of the first slider 14, the movement of the first slider 14 drives the movement of the first control board 12, so that the first control board 12 opens the channel between the cooling chamber 4 and the conveying chamber 5, so that the coolant can enter the interior of the cooling chamber 4.

[0049] S4: At the same time, the movement of the first slider 14 drives the movement of the first connecting plate 19, the movement of the first connecting plate 19 drives the movement of the second slider 17, and the movement of the second slider 17 drives the movement of the second control plate 13, so that the second control plate 13 opens the channel on the other side of the cooling chamber 4 and the conveying chamber 5, so that the coolant can flow out.

[0050] S5: At the same time, the movement of the first connecting plate 19 drives the movement of the second connecting plate 20, the movement of the second connecting plate 20 drives the movement of the third rotating shaft 21, and the movement of the third rotating shaft 21 drives the movement of the tooth block 22, so that the tooth block 22 is embedded in the tooth groove 26 opened inside the first gear 23, the second gear 24 or the third gear 25.

[0051] S6: The start of the second motor 47 drives the rotation of the seventh rotating shaft 46, the rotation of the seventh rotating shaft 46 drives the rotation of the second protrusion 45, the rotation of the second protrusion 45 drives the rotation of the third rotating shaft 21, the rotation of the third rotating shaft 21 drives the rotation of the tooth block 22, the rotation of the tooth block 22 drives the rotation of the first gear 23, the second gear 24 or the third gear 25, the rotation of the first gear 23, the second gear 24 or the third gear 25 drives the rotation of the fourth gear 27, the fifth gear 28 or the sixth gear 29, the rotation of the fourth gear 27, the fifth gear 28 or the sixth gear 29 drives the rotation of the fourth rotating shaft 30, the rotation of the fourth rotating shaft 30 drives the rotation of the first rotating shaft 8, and the rotation of the first rotating shaft 8 drives the rotation of the push plate 9.

[0052] S7: Simultaneously, the rotation of the fourth rotating shaft 30 drives the rotation of the fourth bevel gear 44, which in turn drives the rotation of the third bevel gear 43. The rotation of the third bevel gear 43 drives the rotation of the sixth rotating shaft 42. The rotation of the sixth rotating shaft 42 drives the rotation of the second bevel gear 41. The rotation of the second bevel gear 41 drives the rotation of the first bevel gear 40. The rotation of the first bevel gear 40 drives the rotation of the fifth rotating shaft 39. The rotation of the fifth rotating shaft 39 drives the movement of the fourth connecting plate 36, which, in conjunction with the spring 37, causes the fourth connecting plate 36 to move up and down. The movement of the fourth connecting plate 36 drives the movement of the third connecting plate 34. The movement of the third connecting plate 34 drives the movement of the first protrusion 35, causing the first protrusion 35 to strike the bottom of the filter box 31, ensuring the normal flow of coolant and thus ensuring stable thermal error compensation.

[0053] Example 2

[0054] like Figures 1 to 11 As shown, in this embodiment of the invention, a thermal error compensation device for a CNC machine tool with a non-metallic support component is applied to a thermal error compensation method for a CNC machine tool with a non-metallic support component. The device includes a main body 1, a support base 2 fixedly installed at the bottom of the main body 1, an operating table 3 fixedly installed at the top of the main body 1, and a constant temperature component installed inside the main body 1.

[0055] The constant temperature component includes a cooling chamber 4 located inside the main body 1 of the equipment. An auxiliary constant temperature component is installed inside the cooling chamber 4. Both ends of the cooling chamber 4 are connected to a conveying chamber 5. A control component is installed between the cooling chamber 4 and the conveying chamber 5. A pump 6 is connected to the bottom of the conveying chamber 5. A temperature sensor 7 is installed on the outer wall of the conveying chamber 5. A filter component is installed inside the conveying chamber 5.

[0056] The existing patent CN108422208A discloses an intelligent temperature rise thermal compensation mineral casting bed. This patent discloses the mineral casting bed proposed in this application and the material used for the mineral casting bed. The main body 1 of the equipment in this application adopts the same technical means as this prior art, which will not be described in detail here.

[0057] The main body of the equipment 1 is a non-metallic support component used to support machining equipment, often written as "machine tool".

[0058] The auxiliary temperature control component includes a first rotating shaft 8 disposed inside the cooling chamber 4, which is rotatably connected to the cooling chamber 4. Push plates 9 are evenly installed on the outer wall of the first rotating shaft 8, and a rotating component is disposed inside the push plates 9. A fourth rotating shaft 30 is fixedly connected to the bottom end of the first rotating shaft 8. A third rotating shaft 21 is disposed on one side of the fourth rotating shaft 30 through an adjustment component. A second protrusion 45 is fixedly installed on the outer wall of the bottom end of the third rotating shaft 21. The third rotating shaft 21 and the second protrusion 45 are slidably installed on the inner wall of the seventh rotating shaft 46. A second motor 47 is fixedly connected to the bottom end of the seventh rotating shaft 46.

[0059] By setting up a constant temperature component, when the main body 1 of the equipment is working, the temperature of the main body 1 can be monitored in real time by the temperature sensor 7. When the temperature of the main body 1 of the equipment reaches a certain threshold, the pump 6 can be started to make the coolant circulate in the cooling chamber 4 and the conveying chamber 5 to cool the entire main body 1, thereby compensating for thermal errors and avoiding thermal errors in the main body 1 during operation, which would affect the processing accuracy and ensure the processing accuracy of the machine tool.

[0060] By configuring the auxiliary temperature control component, when the temperature detected by the temperature sensor 7 reaches a certain threshold, the second motor 47 can be started by an external power source. Since the input terminal of the second motor 47 is electrically connected to the external power source via a wire, and the output terminal of the second motor 47 is fixedly connected to the seventh rotating shaft 46, the start of the second motor 47 can drive the rotation of the seventh rotating shaft 46. The rotation of the seventh rotating shaft 46 drives the rotation of the second protrusion 45, which in turn drives the rotation of the third rotating shaft 21. The rotation of the third rotating shaft 21, through the adjustment component, drives the rotation of the fourth rotating shaft 30, which in turn drives the rotation of the first rotating shaft 8. The rotation of the first rotating shaft 8 drives the rotation of the push plate 9, causing the push plate 9 to rotate inside the cooling chamber 4, stirring the coolant, increasing the contact area between the coolant and the main body 1 of the equipment, improving heat exchange efficiency, and thus more effectively absorbing and releasing heat. This avoids the problem of temperature rise rate due to the variety and range of processing methods of the machine tool. In particular, during long-term or continuous processing, the machine tool temperature will rise rapidly, which will increase the thermal error of the machine tool. Adjusting according to different processing methods not only improves the adaptability of the equipment but also reduces the thermal error during machine tool processing.

[0061] like Figure 1-7 As shown, the rotating assembly includes a rotating plate 10 disposed inside the push plate 9, and the rotating plate 10 is rotatably mounted on the inner wall of the push plate 9 via a second rotating shaft 11.

[0062] By setting up the rotating assembly, when the push plate 9 rotates inside the cooling chamber 4, the rotating plate 10 rotates around the second rotating shaft 11 on the inner wall of the push plate 9 under the flow of coolant, which further improves the heat exchange efficiency of the coolant and indirectly improves the efficiency of thermal error compensation.

[0063] like Figure 1-11 As shown, the control assembly includes a first control plate 12 and a second control plate 13 disposed between the cooling chamber 4 and the conveying chamber 5. Both the first control plate 12 and the second control plate 13 are slidably mounted on the inner wall of the equipment body 1. A first slider 14 is fixedly mounted on both ends of the first control plate 12. A threaded rod 15 is connected to the inner wall of one of the first sliders 14. A first motor 16 is fixedly mounted on the bottom end of the threaded rod 15. A second slider 17 is fixedly mounted on both ends of the second control plate 13. A guide rod 18 is slidably mounted on the inner wall of the second slider 17. The guide rod 18 is fixedly mounted on the inner wall of the equipment body 1. A first connecting plate 19 is fixedly mounted between the second slider 17 and the first slider 14.

[0064] By setting the control components, when the temperature detected by the temperature sensor 7 reaches a certain threshold, the first motor 16 can be started by an external power source. Since the input end of the first motor 16 is electrically connected to the external power source through a wire, and the output end of the first motor 16 is fixedly connected to the threaded rod 15, the start of the first motor 16 can drive the rotation of the threaded rod 15. Since the threaded rod 15 and the first slider 14 are connected by internal and external threads, the rotation of the threaded rod 15 can drive the first slider 14 to move, causing the first slider 14 to drive the first control board 12 to move, opening the channel between the cooling chamber 4 and the conveying chamber 5, so that the coolant can enter the interior of the cooling chamber 4.

[0065] At the same time, the movement of the first slider 14 drives the movement of the first connecting plate 19, the movement of the first connecting plate 19 drives the movement of the second slider 17, and the movement of the second slider 17 drives the movement of the second control plate 13, so that the movement of the second control plate 13 opens the channel between the cooling chamber 4 and the other side of the conveying chamber 5, so that the coolant inside the cooling chamber 4 can flow out and be exchanged.

[0066] The flow rate of the coolant can be controlled by the PLC to move the first control board 12 and the second control board 13 according to the temperature, thereby reducing thermal errors and adjusting the flow rate according to different processing methods to improve the adaptability of the device.

[0067] like Figure 1-11As shown, the adjustment assembly includes a fourth gear 27, a fifth gear 28, and a sixth gear 29 fixedly installed on the outer wall of the fourth rotating shaft 30. A first gear 23, a second gear 24, and a third gear 25 are respectively meshed on one side of the fourth gear 27, the fifth gear 28, and the sixth gear 29. The first gear 23, the second gear 24, and the third gear 25 are all installed on the outer wall of the third rotating shaft 21. The inner walls of the first gear 23, the second gear 24, and the third gear 25 are all provided with tooth grooves 26. A tooth block 22 is embedded in the inner wall of one of the tooth grooves 26. The tooth block 22 is fixedly installed on the outer wall of the third rotating shaft 21.

[0068] By adjusting the component settings, when the first connecting plate 19 moves, the movement of the first connecting plate 19 drives the movement of the second connecting plate 20, which in turn drives the movement of the third rotating shaft 21. The movement of the third rotating shaft 21 drives the movement of the toothed block 22, causing the toothed block 22 to move and embed into the toothed groove 26 opened in the inner wall of the first gear 23, the second gear 24, or the third gear 25. The rotation of the third rotating shaft 21 drives the rotation of the toothed block 22, which in turn drives the rotation of the first gear 23, the second gear 24, or the third gear 25. The rotation of the first gear 23, the second gear 24, or the third gear 25 drives the rotation of the fourth gear 27, the fifth gear 28, or the sixth gear 29. The rotation of the fourth gear 27, the fifth gear 28, or the sixth gear 29 drives the rotation of the fourth rotating shaft 30. The fourth rotating shaft 30 provides power for the rotation of the auxiliary temperature control component, improving the adaptability of the equipment.

[0069] like Figure 1-11 As shown, a second connecting plate 20 is fixedly installed on one side of the first connecting plate 19, and the end of the second connecting plate 20 away from the first connecting plate 19 is sleeved on the outer wall of the third rotating shaft 21.

[0070] With the second connecting plate 20 in place, when the first control plate 12 and the second control plate 13 move, the movement of the first connecting plate 19 can drive the movement of the second connecting plate 20, and the movement of the second connecting plate 20 can drive the movement of the first connecting plate 19, thereby moving the adjustment component and synchronously adjusting the speed of the auxiliary constant temperature component.

[0071] like Figure 1-11 As shown, the number of teeth on the outer walls of the first gear 23, the second gear 24 and the third gear 25 increases sequentially, while the number of teeth on the outer walls of the fourth gear 27, the fifth gear 28 and the sixth gear 29 decreases sequentially.

[0072] The number of teeth on the outer walls of the first gear 23, the second gear 24, and the third gear 25 increases sequentially, while the number of teeth on the outer walls of the fourth gear 27, the fifth gear 28, and the sixth gear 29 decreases sequentially. When the third rotating shaft 21 rotates, the rotation of the fourth gear 27, the fifth gear 28, or the sixth gear 29 can be driven by the rotation of the tooth block 22 and the first gear 23, the second gear 24, or the third gear 25, so that the rotation speed of the fourth rotating shaft 30 is different. This makes it convenient to adjust the rotation speed of the auxiliary temperature control component according to the different flow rates when the control component controls the flow rate of the coolant, thereby improving the stability of the device.

[0073] like Figure 1-11 As shown, the filter assembly includes a filter box 31 that is slidably installed on the inner wall of the device body 1. The filter box 31 is slidably installed inside the device body 1, and a tapping component is provided at the bottom of the filter box 31.

[0074] By configuring the filtration assembly, when the coolant inside the delivery chamber 5 flows from one side of the second control plate 13, it can flow through the filter box 31 and be filtered through the through-holes at the bottom of the filter box 31. During use, the coolant is affected by environmental and operating conditions, and may be contaminated by impurities, pollutants, and deposits. Therefore, regular filtration of the coolant is necessary. Filtration helps remove impurities and pollutants, maintains the cleanliness and normal operation of the cooling system, extends the service life of the coolant, and improves the effectiveness of thermal error compensation.

[0075] like Figure 1-11 As shown, a control door 32 is provided on one side of the filter box 31. The control door 32 is rotatably installed on the side wall of the main body 1 of the equipment, and a handle 33 is fixedly connected to one side of the control door 32.

[0076] By controlling the door 32 and handle 33, when it is necessary to clean the impurities in the filter box 31, the door 32 can be opened by pulling it. The inner wall of the main body 1 of the equipment has a sliding groove for the filter box 31 to slide, so that the filter box 31 can be directly pulled out to clean the impurities inside the filter box 31. This prevents the filter box 31 from being clogged by too many impurities after a period of use, which would slow down the flow of coolant and affect the constant temperature effect.

[0077] like Figure 1-11As shown, the striking assembly includes a third connecting plate 34 disposed below the filter box 31. The top of the third connecting plate 34 is uniformly connected with first protrusions 35. A fourth connecting plate 36 is fixedly installed on one side of the third connecting plate 34. The fourth connecting plate 36 is slidably installed on the inner wall of the equipment body 1. A spring 37 is installed between the fourth connecting plate 36 and the equipment body 1. A cam 38 is provided at the bottom of the spring 37. A fifth rotating shaft 39 is fixedly installed on the inner wall of the cam 38. A first bevel gear 40 is fixedly installed at one end of the fifth rotating shaft 39. A second bevel gear 41 is fixedly meshed at the top of the first bevel gear 40. A sixth rotating shaft 42 is fixedly connected to the inner wall of the second bevel gear 41. A third bevel gear 43 is fixedly installed at the other end of the sixth rotating shaft 42. A fourth bevel gear 44 is meshed at the top of the third bevel gear 43. The fourth bevel gear 44 is fixedly installed at the bottom of the fourth rotating shaft 30.

[0078] When the fourth rotating shaft 30 rotates, its rotation drives the fourth bevel gear 44 to rotate, which in turn drives the third bevel gear 43 to rotate. The third bevel gear 43 then drives the sixth rotating shaft 42 to rotate, which in turn drives the second bevel gear 41 to rotate. The second bevel gear 41 then drives the first bevel gear 40 to rotate, which in turn drives the fifth rotating shaft 39 to rotate. The fifth rotating shaft 39 then drives the cam 38 to rotate, and the cam 38 then moves the fourth connecting plate 36. When the highest point of the cam 38 contacts the bottom end of the fourth connecting plate 36, it drives the fourth connecting plate 36 to move upward, causing the fourth connecting plate 36 to compress the spring 37, deforming the spring 37 to store elastic potential energy. The elastic potential energy is then released through the spring 37, causing the fourth connecting plate 36 to move up and down during the rotation of the cam 38. The movement of the fourth connecting plate 36 drives the movement of the third connecting plate 34, which in turn drives the movement of the first protrusion 35. This causes the top of the first protrusion 35 to intermittently contact the bottom end of the filter box 31, striking the filter box 31 and facilitating the flow of coolant inside the filter box 31.

[0079] Working principle and usage process:

[0080] When the main body of the equipment 1 is working, the temperature of the main body of the equipment 1 is monitored in real time by the temperature sensor 7. When the temperature reaches a certain threshold, the pump 6, the first motor 16 and the second motor 47 are started by the external power supply.

[0081] At the same time, the start of pump 6 causes the coolant to circulate in the cooling chamber 4 and the conveying chamber 5, cooling the entire main body 1 of the equipment and thus compensating for thermal errors.

[0082] At the same time, the start of the first motor 16 drives the rotation of the threaded rod 15, the rotation of the threaded rod 15 drives the movement of the first slider 14, and the movement of the first slider 14 drives the movement of the first control board 12, so that the first control board 12 opens the channel between the cooling chamber 4 and the conveying chamber 5, so that the coolant can enter the interior of the cooling chamber 4.

[0083] At the same time, the movement of the first slider 14 drives the movement of the first connecting plate 19, the movement of the first connecting plate 19 drives the movement of the second slider 17, and the movement of the second slider 17 drives the movement of the second control plate 13, so that the second control plate 13 opens the channel on the other side of the cooling chamber 4 and the conveying chamber 5, so that the coolant can flow out.

[0084] At the same time, the movement of the first connecting plate 19 drives the movement of the second connecting plate 20, the movement of the second connecting plate 20 drives the movement of the third rotating shaft 21, and the movement of the third rotating shaft 21 drives the movement of the tooth block 22, so that the tooth block 22 is embedded in the tooth groove 26 opened inside the first gear 23, the second gear 24 or the third gear 25.

[0085] Simultaneously, the starting of the second motor 47 drives the rotation of the seventh rotating shaft 46, the rotation of the seventh rotating shaft 46 drives the rotation of the second protrusion 45, the rotation of the second protrusion 45 drives the rotation of the third rotating shaft 21, the rotation of the third rotating shaft 21 drives the rotation of the tooth block 22, the rotation of the tooth block 22 drives the rotation of the first gear 23, the second gear 24 or the third gear 25, the rotation of the first gear 23, the second gear 24 or the third gear 25 drives the rotation of the fourth gear 27, the fifth gear 28 or the sixth gear 29, the rotation of the fourth gear 27, the fifth gear 28 or the sixth gear 29 drives the rotation of the fourth rotating shaft 30, the rotation of the fourth rotating shaft 30 drives the rotation of the first rotating shaft 8, and the rotation of the first rotating shaft 8 drives the rotation of the push plate 9.

[0086] Simultaneously, the rotation of the fourth rotating shaft 30 drives the rotation of the fourth bevel gear 44, which in turn drives the rotation of the third bevel gear 43. The rotation of the third bevel gear 43 drives the rotation of the sixth rotating shaft 42. The rotation of the sixth rotating shaft 42 drives the rotation of the second bevel gear 41. The rotation of the second bevel gear 41 drives the rotation of the first bevel gear 40. The rotation of the first bevel gear 40 drives the rotation of the fifth rotating shaft 39. The rotation of the fifth rotating shaft 39 drives the movement of the fourth connecting plate 36, which, in conjunction with the spring 37, causes the fourth connecting plate 36 to move up and down. The movement of the fourth connecting plate 36 drives the movement of the third connecting plate 34. The movement of the third connecting plate 34 drives the movement of the first protrusion 35, causing the first protrusion 35 to strike the bottom of the filter box 31.

[0087] When it is necessary to clean the impurities inside the filter box 31, the control door 32 can be opened by pulling it. The inner wall of the main body 1 of the equipment has a sliding groove for the filter box 31 to slide, so that the filter box 31 can be directly pulled out to clean the impurities inside the filter box 31.
