Description

Technical Field

[0001] The present invention relates to the technical field of gantry machining centers, and specifically to a machining device integrated with thermal deformation compensation. Background Technique

[0002] A gantry machining center is a machining device with the characteristics of high precision, high efficiency, and high stability. Its main structure consists of a gantry column and a crossbeam made of cast iron or steel plates, and components such as the X, Y, Z axes, spindle, and feed system are installed to achieve the machining of complex parts.

[0003] During the high-speed and high-precision machining process of a gantry machining center, due to factors such as friction between components inside the machine tool, cutting force, and motor heat generation, a large amount of heat will be generated. If this heat cannot be dissipated in time, a temperature gradient will be formed inside the machine tool, resulting in thermal deformation of each component of the machine tool. Thermal deformation will directly affect the geometric accuracy and machining stability of the machine tool, thereby reducing machining accuracy and product quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a machining device integrated with thermal deformation compensation to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A machining device integrated with thermal deformation compensation, the machining device includes a base, a workbench, columns, a crossbeam, a slide, a ram, a spindle, a first cooling mechanism, and a second cooling mechanism. The base is connected to the workbench, the columns are fixedly connected to the crossbeam, the slide is slidably connected to the crossbeam, the ram is connected to the slide, the spindle is connected to the ram, the first cooling mechanism is connected to the slide and the ram, and the second cooling mechanism is connected to the workbench and the slide.

[0007] The machining device enables the spindle to move in the X, Y, and Z axes through the mutual cooperation of the base, workbench, columns, crossbeam, slide, and ram to complete the machining of the workpiece. During the machining process of the workpiece, components such as the workbench, slide, ram, and spindle will all generate heat. Due to the properties of metals, heat generation will cause thermal expansion and contraction, resulting in thermal deformation errors. By cooling the relevant mechanical structures through the first cooling mechanism and the second cooling mechanism, the thermal deformation errors are reduced.

[0008] Further, the workbench includes a bearing base, a first motor, a first lead screw, a first nut, a first guide rail, and a first slider. The bearing base is slidably connected to the base. The first motor is fixedly connected to the base. The output end of the first motor is fixedly connected to the first lead screw. The first nut is threadedly connected to the first lead screw. The first nut is fixedly connected to the bearing base. The first lead screw passes through a through hole in the bearing base. The first guide rail is fixedly connected to the base. The first slider is slidably connected to the first guide rail. The first slider is fixedly connected to the bearing base. The second cooling mechanism is connected to the bearing base.

[0009] Driven by the first motor, the first lead screw rotates. With the cooperation of the first lead screw and the first nut, as the first nut linearly moves on the first lead screw, the bearing base also undergoes a corresponding displacement. To achieve smoother and more precise movement, the bearing base is also equipped with a first slider, which can closely adhere to and slide on the first guide rail. The first guide rail, as a guiding component, its highly precision-machined surface ensures the smoothness and straightness of the slider's movement, thus ensuring that the movement of the workbench in the X-axis direction is both precise and stable.

[0010] Further, the sliding seat includes a housing, a second motor, a gear, a rack, a second guide rail, and a second slider. The housing is slidably connected to the crossbeam. The second motor is fixedly connected to the housing. The output end of the second motor is fixedly connected to the gear. The rack is meshed with the gear. The rack is fixedly connected to the crossbeam. The second guide rail is fixedly connected to the crossbeam. The second slider is slidably connected to the second guide rail. The second slider is fixedly connected to the housing. The housing is connected to the ram. The housing is fixedly connected to the first cooling mechanism.

[0011] The housing, as a solid and precise component, has a second motor ingeniously installed inside. The second motor drives the connected gear to rotate. As the gear rotates, the gear linearly moves on the rack, and this movement is further transmitted through the tight connection between the bottom of the housing and the second slider. The second slider can closely adhere to the second guide rail and slide along the guide rail as the gear rotates, enabling the entire transmission system to move smoothly and precisely in the Y-axis direction.

[0012] Further, the ram includes a box body, a linear guide rail, a third slider, a third motor, a second lead screw, and a second nut. The third slider is fixedly connected to the housing. There is a sliding groove on the housing. The box body is slidably connected to the sliding groove. The linear guide rail is fixedly connected to the box body. The housing has four round holes, and there are four linear guide rails. The linear guide rails are slidably connected to the round holes. The third slider is fixedly connected to the housing. The third slider is slidably connected to the linear guide rail. The third motor is fixedly connected to the box body. The output end of the third motor is fixedly connected to the second lead screw. There are two second lead screws and two second nuts. The second nuts are threadedly connected to the second lead screws. The second nuts are fixedly connected to the housing. The box body is fixedly connected to the spindle.

[0013] The No. 3 motor inside the box drives the No. 2 lead screw to rotate. With the cooperation of the No. 2 lead screw and the No. 2 nut, as the No. 2 nut linearly moves on the No. 2 lead screw, the box also undergoes corresponding displacement. To achieve smoother and more precise movement, the box is also equipped with a No. 3 slider, which can closely adhere to and slide on the linear guide rail. The linear guide rail, as a guiding component, its highly precision-machined surface ensures the smoothness and straightness of the slider's movement, thus ensuring that the ram moves precisely and stably in the Z-axis direction.

[0014] Furthermore, the main shaft includes a sleeve, a No. 4 motor, and a transmission box. The sleeve is connected to the No. 1 cooling mechanism, the No. 4 motor is fixedly connected to the box, the output end of the No. 4 motor is drivingly connected to the sleeve, and the transmission box is tightly connected to the sleeve.

[0015] The box, acting as the core for support and protection, has a No. 4 motor installed inside it. As the heart of the power source, it steadily and precisely controls the entire movement process of the main shaft. When the No. 4 motor starts and rotates at high speed, it transmits this power to the transmission box through a precise transmission mechanism, causing the transmission box to start rotating in a smooth and continuous manner. As the transmission box rotates, the sleeve also rotates synchronously, not only transmitting the rotational power but also bearing various loads during the machining process. Through the cooling grooves on the sleeve, when the coolant is pumped into the cooling grooves, they quickly and evenly cover the contact surface between the sleeve and the transmission box, forming a thin cooling film. This cooling film not only effectively reduces the heat generated by the transmission box due to long-term high-speed operation but also quickly takes away the heat through heat conduction, thus avoiding the problem of thermal deformation caused by excessive temperature.

[0016] Furthermore, the No. 1 cooling mechanism includes a liquid supply tank, a liquid supply pipe, a recovery pipe, a recovery tank, a cooling pipe, a nozzle, and a No. 1 temperature sensor. The output end of the liquid supply tank is connected to the liquid supply pipe. There are two liquid supply pipes, and the liquid supply pipes are fixedly connected to the outer shell. The liquid supply pipes pass through the box and are connected to the sleeve. There are two recovery pipes, and the recovery pipes are connected to the recovery tank and the outer shell. There is a collection groove on the outer shell, and the recovery pipes are connected to the collection groove through pipelines. The recovery pipes pass through the box and are connected to the sleeve. The sleeve has cooling grooves, and the cooling grooves are connected to the liquid supply pipes and the recovery pipes. The cooling pipe is connected to the recovery tank and the liquid supply tank. The nozzle is fixedly connected to the outer shell. There are three No. 1 temperature sensors, and the No. 1 temperature sensors are fixedly connected to the outer shell and the sleeve.

[0017] When the precise No. 1 temperature sensor built into the housing keenly captures that the gear temperature is about to rise to the critical point that causes thermal deformation, it immediately triggers the response mechanism of the intelligent cooling system. The coolant is accurately distributed through the liquid supply tank and injected into the liquid supply pipe with the help of an efficient pumping system to achieve precise directional supply. The coolant is sprayed out along the liquid supply pipe through the nozzle in the form of fine atomization, accurately covering and effectively cooling the gear and its matching rack, effectively curbing the potential risk of thermal deformation. The coolant enters the recovery pipe through the collection tank. When the inside of the transmission box is also facing the threat of a sharp rise in temperature and is detected by its built-in No. 1 temperature sensor, another independent cooling circuit is quickly activated. This circuit uses another supply The liquid pipe directly pumps the coolant into a cooling tank designed to cope with high temperatures, thereby achieving efficient cooling of the transmission box. After fully absorbing the heat, the coolant is discharged in an orderly manner from the recovery pipe. The entire process is based on the principle of heat conduction, which quickly and efficiently transfers heat and ensures the stability and safety of the mechanical structure. The coolant in the recovery pipe is then guided to the recovery tank, and passes through the filtration system in the recovery tank to remove impurities and particulate matter, ensuring the purity and recycling efficiency of the coolant. Subsequently, the filtered coolant is further cooled by the cooling pipe, and its temperature is restored to the ideal state, and finally circulates back to the liquid supply tank, waiting for the next cooling task, forming a closed-loop and efficient coolant recycling system.

[0018] Furthermore, the No. 2 cooling mechanism includes an air compressor, an air supply pipe, an air outlet block, and a No. 2 temperature sensor. The output end of the air compressor is connected to the air supply pipe. Three air supply pipes are provided. Two air outlet blocks are provided. The air outlet block is connected to the air supply pipe. The air outlet block is fixedly connected to the outer shell. The air outlet block is provided with an air outlet. The air outlet is located on the side close to the No. 2 nut. Three No. 2 temperature sensors are provided. The No. 2 temperature sensor is fixedly connected to the No. 2 nut. The No. 2 temperature sensor is arranged in the through hole of the bearing seat. The No. 2 temperature sensor is fixedly connected to the bearing seat.

[0019] When the No. 2 temperature sensor keenly captures that the temperature of the No. 2 nut is about to rise to the critical point causing thermal deformation, the response mechanism of the intelligent cooling system is immediately triggered. The high-pressure air is input into the air pipe through the air compressor. The high-pressure air reaches the air outlet block through the air pipe and is sprayed out from the air outlet to cool the No. 2 nut. When the temperature of another No. 2 temperature sensor installed on the bearing seat is about to rise to the critical point causing thermal deformation, an independent cooling circuit is quickly activated. This circuit uses another air pipe to transport high-pressure air to the through hole on the bearing seat. The high-pressure air reaches the No. 1 nut through the through hole and cools it. It is then output from the other end of the other through hole. The whole process is based on the principle of heat conduction, which quickly and efficiently transfers heat and ensures the stability and safety of the mechanical structure.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the No. 1 temperature sensor of the present invention detects that the temperature of the gear is too high, the coolant is accurately dispensed through the No. 1 cooling mechanism's liquid supply box, and is injected into the liquid supply pipe with the help of an efficient pump to achieve precise directional supply. The coolant is sprayed out in the form of fine atomization along the liquid supply pipe through the nozzle, accurately covering and effectively cooling the gear and its matching rack. When the interior of the transmission box is also facing the threat of a sharp rise in temperature and is detected by its built-in No. 1 temperature sensor, another independent cooling circuit is quickly activated. This circuit uses another liquid supply pipe to directly pump the coolant into a cooling tank designed specifically for high temperatures. In order to realize efficient cooling of the transmission box, when the No. 2 temperature sensor detects that the temperature of the No. 2 nut is too high, the No. 2 cooling mechanism inputs high-pressure air into the air pipe through the air compressor. The high-pressure air reaches the air outlet block through the air pipe and is sprayed out from the air outlet to cool the No. 2 nut. Another air pipe transports the high-pressure air to the through hole on the bearing seat. The high-pressure air reaches the No. 1 nut through the through hole and cools it. During the high-speed and high-precision machining process of the gantry machining center, a large amount of heat is generated by the internal components. Based on the principle of heat conduction, the heat can be transferred quickly and efficiently, thereby achieving the effect of thermal deformation compensation and ensuring the stability and safety of the mechanical structure.

[0035] The processing device enables the spindle 7 to move in the X, Y, and Z axes through the mutual cooperation of the base 1, the workbench 2, the column 3, the crossbeam 4, the carriage 5, and the ram 6 to complete the processing of the workpiece. During the workpiece processing, components such as the workbench 2, the carriage 5, the ram 6, and the spindle 7 will generate heat. Due to the properties of metals, heat will cause the phenomenon of thermal expansion and contraction, resulting in thermal deformation errors. The first cooling mechanism 8 and the second cooling mechanism 9 are used to cool the relevant mechanical structures, reducing the thermal deformation errors.

[0036] As Figure 2 shown, the workbench 2 includes a carrier seat 21, a first motor 22, a first lead screw 23, a first nut 24, a first guide rail 25, and a first slider 26. The carrier seat 21 is slidably connected to the base 1. The first motor 22 is fixedly connected to the base 1. The output end of the first motor 22 is fixedly connected to the first lead screw 23.

The first lead screw 23 passes through the through hole on the carrier seat 21. The first guide rail 25 is fixedly connected to the base 1. The first slider 26 is slidably connected to the first guide rail 25. The first slider 26 is fixedly connected to the carrier seat 21. The second cooling mechanism 9 is connected to the carrier seat 21.

[0037] The first motor 22 drives the first lead screw 23 to rotate. With the cooperation of the first lead screw 23 and the first nut 24, as the first nut 24 linearly moves on the first lead screw 23, the carrier seat 21 also undergoes corresponding displacement. To achieve smoother and more precise movement, the carrier seat 21 is also equipped with a first slider 26, which can closely adhere to and slide on the first guide rail 25. The first guide rail 25, as a guiding component, its highly precision-machined surface ensures the smoothness and straightness of the slider's sliding, thus ensuring the precise and stable movement of the workbench 2 in the X-axis direction.

[0038] As Figure 3 shown, the carriage 5 includes a housing 51, a second motor 52, a gear 53, a rack 54, a second guide rail 55, and a second slider 56. The housing 51 is slidably connected to the crossbeam 4. The second motor 52 is fixedly connected to the housing 51. The output end of the second motor 52 is fixedly connected to the gear 53. The rack 54 meshes with the gear 53. The rack 54 is fixedly connected to the crossbeam 4. The second guide rail 55 is fixedly connected to the crossbeam 4. The second slider 56 is slidably connected to the second guide rail 55. The second slider 56 is fixedly connected to the housing 51. The housing 51 is connected to the ram 6, and the housing 51 is fixedly connected to the first cooling mechanism 8.

[0039] The outer shell 51, being a sturdy and precise component, has the second motor 52 ingeniously installed inside. The second motor 52 drives the connected gear 53 to rotate. As the gear 53 rotates, it linearly moves on the rack 54, and this movement is further transmitted through the tight connection between the bottom of the outer shell 51 and the second slider 56. The second slider 56 can closely fit on the second guide rail 55 and slide along the guide rail as the gear 53 rotates, enabling the entire transmission system to move smoothly and precisely along the Y-axis direction.

[0040] As Figures 4 to 5 shown, the ram 6 includes a box body 61, linear guide rails 62, third sliders 63, third motors 64, second lead screws 65, and second nuts 66. The third sliders 63 are fixedly connected to the outer shell 51. The outer shell 51 is provided with sliding grooves 511, and the box body 61 is slidably connected to the sliding grooves 511. The linear guide rails 62 are fixedly connected to the box body 61. The outer shell 51 is provided with four round holes 512, and there are four linear guide rails 62. The linear guide rails 62 are slidably connected to the round holes 512. The third sliders 63 are fixedly connected to the outer shell 51, and the third sliders 63 are slidably connected to the linear guide rails 62.

[0041] Driven by the third motor 64 inside the box body 61, the second lead screw 65 rotates. With the cooperation of the second lead screw 65 and the second nut 66, as the second nut 66 linearly moves on the second lead screw 65, the box body 61 also undergoes corresponding displacement. To achieve smoother and more precise movement, the box body 61 is also equipped with third sliders 63, which can closely fit and slide on the linear guide rails 62. The linear guide rails 62, as guiding components, ensure the smoothness and straightness of the slider sliding with their highly precision-machined surfaces, thus ensuring that the ram 6 moves precisely and stably in the Z-axis direction.

[0042] As Figure 6 shown, the main shaft 7 includes a sleeve 71, a fourth motor 72, and a transmission box 73. The sleeve 71 is connected to the first cooling mechanism 8, the fourth motor 72 is fixedly connected to the box body 61, the output end of the fourth motor 72 is drivingly connected to the sleeve 71, and the transmission box 73 is tightly connected to the sleeve 71.

[0043] The housing 61 serves as the core for support and protection. The fourth motor 72 installed inside it, acting as the heart of the power source, steadily and precisely controls the entire movement process of the main shaft 7. When the fourth motor 72 starts and rotates at high speed, it transmits this power to the transmission box 73 through a precise transmission mechanism, causing the transmission box 73 to start rotating in a stable and continuous manner. As the transmission box 73 rotates, the sleeve 71 also rotates synchronously, not only transmitting the rotational power but also bearing various loads during the processing. Through the cooling grooves 711 on the sleeve 71, when the coolant is pumped into the cooling grooves 711, they quickly and evenly cover the contact surface between the sleeve 71 and the transmission box 73, forming a thin cooling film. This cooling film not only effectively reduces the heat generated by the transmission box 73 due to long-term high-speed operation but also quickly takes away the heat through heat conduction, thus avoiding the problem of thermal deformation caused by excessive temperature.

[0044] As Figure 1 , Figure 3 , Figure 6 , Figure 7 shown, the first cooling mechanism 8 includes a liquid supply tank 81, a liquid supply pipe 82, a recovery pipe 83, a recovery tank 84, a cooling pipe 85, a nozzle 86, and a first temperature sensor 87. The output end of the liquid supply tank 81 is connected to the liquid supply pipe 82. There are two liquid supply pipes 82, and the liquid supply pipes 82 are fixedly connected to the outer shell 51. The liquid supply pipes 82 pass through the housing 61 and are connected to the sleeve 71. There are two recovery pipes 83, and the recovery pipes 83 are connected to the recovery tank 84. The recovery pipes 83 are connected to the outer shell 51. A collection groove 513 is provided on the outer shell 51, and the recovery pipes 83 are in pipeline connection with the collection groove 513. The recovery pipes 83 pass through the housing 61 and are connected to the sleeve 71. The sleeve 71 is provided with cooling grooves 711, and the cooling grooves 711 are connected to the liquid supply pipes 82 and the recovery pipes 83. The cooling pipe 85 is connected to the recovery tank 84 and the liquid supply tank 81. The nozzle 86 is fixedly connected to the outer shell 51. There are three first temperature sensors 87, and the first temperature sensors 87 are fixedly connected to the outer shell 51 and the sleeve 71.

[0045] When the precise No. 1 temperature sensor 87 built into the housing 51 keenly detects that the temperature of the gear 53 is about to rise to the critical point that causes thermal deformation, the response mechanism of the intelligent cooling system is immediately triggered. The coolant is accurately prepared through the liquid supply tank 81, and is injected into the liquid supply pipe 82 with the help of an efficient pumping system to achieve precise directional supply. The coolant is sprayed out in the form of fine atomization along the liquid supply pipe 82 through the nozzle 86, accurately covering and effectively cooling the gear 53 and its matching rack 54, effectively curbing the potential risk of thermal deformation. The coolant enters the recovery pipe 83 through the collection tank 513. When the transmission case 73 is also threatened by a sharp rise in temperature and is detected by its built-in No. 1 temperature sensor 87, another independent cooling circuit is quickly activated. This circuit uses Another liquid supply pipe 82 directly pumps the coolant into the cooling tank 711 designed to cope with high temperatures, thereby achieving efficient cooling of the transmission box 73. After fully absorbing the heat, the coolant is discharged in an orderly manner from the recovery pipe 83. The entire process is based on the principle of heat conduction, which quickly and efficiently transfers heat and ensures the stability and safety of the mechanical structure. The coolant in the recovery pipe 83 is then guided to the recovery box 84, and the impurities and particulate matter are removed through the filtration system in the recovery box 84, ensuring the purity and recycling efficiency of the coolant. Subsequently, the filtered coolant is further cooled by the cooling pipe 85, and its temperature is restored to an ideal state, and finally circulates back to the liquid supply tank 81, waiting for the next cooling task, forming a closed-loop and efficient coolant recycling system.

[0046] like Figures 1 to 2 , Figures 8 to 9 As shown, the No. 2 cooling mechanism 9 includes an air compressor 91, an air supply pipe 92, an air outlet block 93, and a No. 2 temperature sensor 94. The output end of the air compressor 91 is connected to the air supply pipe 92. Three air supply pipes 92 are provided. Two air outlet blocks 93 are provided. The air outlet block 93 is connected to the air supply pipe 92. The air outlet block 93 is fixedly connected to the outer shell 51. The air outlet block 93 is provided with an air outlet 931. The air outlet 931 is located on the side close to the No. 2 nut 66. Three No. 2 temperature sensors 94 are provided. The No. 2 temperature sensor 94 is fixedly connected to the No. 2 nut 66. The No. 2 temperature sensor 94 is arranged in the through hole of the support seat 21. The No. 2 temperature sensor 94 is fixedly connected to the support seat 21.

[0047] When the second temperature sensor 94 acutely detects that the temperature of the second nut 66 is about to climb to the critical point that triggers thermal deformation, it immediately activates the response mechanism of the intelligent cooling system. High-pressure air is input into the air delivery pipe 92 through the air compressor 91. The high-pressure air reaches the air outlet block 93 through the air delivery pipe 92 and is ejected from the air outlet 931 to cool the second nut 66. When the temperature of another second temperature sensor 94 installed on the bearing seat 21 is about to climb to the critical point that triggers thermal deformation, a set of independent cooling circuits is quickly activated. This circuit uses another air delivery pipe 92 to deliver high-pressure air to the through hole on the bearing seat 21. The high-pressure air reaches the first nut 24 through the through hole and cools it, and then is output from the other end of another through hole. The whole process is based on the principle of heat conduction, quickly and efficiently transferring heat, ensuring the stability and safety of the mechanical structure.

[0048] The working principle of the present invention:

[0049] The first motor 22 drives the first lead screw 23 to rotate. With the cooperation of the first lead screw 23 and the first nut 24, and through the cooperation of the first slider 26 and the first guide rail 25, the movement of the workbench 2 in the X-axis direction is realized. The second motor 52 drives the gear 53 to rotate, and the gear 53 linearly moves on the rack 54. Through the cooperation of the second slider 56 and the second guide rail 55 of the housing 51, the entire transmission system can move along the Y-axis direction. The third motor 64 in the box body 61 drives the second lead screw 65 to rotate. With the cooperation of the second lead screw 65 and the second nut 66, and through the cooperation of the third slider 63 and the linear guide rail 62, the movement of the ram 6 in the Z-axis direction is realized. When the fourth motor 72 installed inside the box body 61 starts and rotates at high speed, the power is transmitted to the transmission case 73, causing the transmission case 73 to start rotating in a stable and continuous manner, and the sleeve 71 also rotates synchronously, realizing the rotation of the main shaft 7. When the first temperature sensor 87 detects that the temperature of the gear 53 is about to cause thermal deformation, the coolant supply tank 81 injects the coolant into the supply pipe 82 with the help of an efficient pump. The coolant flows along the supply pipe 82 and is sprayed out in an atomized form through the nozzle 86 to cool the gear 53 and the rack 54. The coolant enters the recovery pipe 83 through the collection groove 513. When the first temperature sensor 87 inside the transmission case 73 detects a sharp rise in temperature, the coolant supply tank 81 uses another supply pipe 82 to pump the coolant into the cooling groove 711 to achieve efficient cooling of the transmission case 73. After fully absorbing the heat, the coolant is discharged from the recovery pipe 83 in an orderly manner and then guided into the recovery tank 84. Through the filtration system in the recovery tank 84, impurities and particulate matters are removed, ensuring the purity and recycling efficiency of the coolant. After further cooling treatment through the cooling pipe 85, it finally returns to the coolant supply tank 81, forming a closed-loop and efficient coolant recycling system. When the second temperature sensor 94 detects that the temperature of the second nut 66 causes thermal deformation, the air compressor 91 inputs high-pressure air into the air supply pipe 92. The high-pressure air reaches the air outlet block 93 through the air supply pipe 92 and is sprayed out from the air outlet 931 to cool the second nut 66. When another second temperature sensor 94 installed on the bearing seat 21 detects too high a temperature, another air supply pipe 92 conveys the high-pressure air to the through hole on the bearing seat 21. The high-pressure air reaches the first nut 24 through the through hole and cools it, and then is output from the other end of another through hole. The entire process of the two cooling systems is based on the principle of heat conduction, quickly and efficiently transferring heat, ensuring the stability and safety of the mechanical structure.
