Description

Technical Field

[0001] This utility model relates to the technical field of CNC machine tools, specifically to an automatic leveling support structure for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] The Chinese patent announcement CN217571801U discloses a stable support structure for a CNC machine tool. The key technical features are that it includes a body and support components for stabilizing the body. The support components include fixed plates respectively disposed on both sides of the body, a motor disposed on the top of the fixed plate, a screw connected to the motor, a lifting plate sleeved on the outside of the screw, support legs respectively disposed on both sides of the bottom of the lifting plate, support plates disposed at the bottom of the support legs, a rolling component for moving the body, and an anti-rotation component for preventing the lifting plate from rotating.

[0004] In the above solution, the main body can be supported by a fixed plate, motor, screw, lifting plate, support leg, support plate, rolling parts and anti-rotation parts, which leads to the following disadvantage: the support structure does not have an automatic leveling function, which causes the whole body to tilt when placed on uneven ground. Utility Model Content

[0005] The purpose of this invention is to provide an automatic leveling support structure for CNC machine tools, so as to solve the problem that the support structure does not have an automatic leveling function, and thus the whole structure tilts when placed on uneven ground.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an automatic leveling support structure for a CNC machine tool, comprising a support frame, the support frame being fixed to the bottom surface of the machine tool body, a groove being provided on the top surface of the support frame, a dual-axis tilt sensor being fixed inside the groove, the dual-axis tilt sensor being located in the middle of the support frame, a plurality of support cylinders being provided below the support frame, a cylinder being fixed inside each of the plurality of support cylinders, a U-shaped seat being fixed on the bottom surface of each of the four corners of the support frame, a rotating hole being provided on the left and right sides of each of the plurality of U-shaped seats, a connecting block being rotatably provided inside each of the plurality of U-shaped seats, the bottom surface of each of the plurality of connecting blocks being connected to one end of a telescopic rod of each of the plurality of cylinders, a rotating shaft being fixed on the left and right sides of each of the plurality of connecting blocks, two rotating shafts being rotatably provided in two rotating holes, a PLC controller being fixed on the front side of the outer wall of the support frame, and the dual-axis tilt sensor and the cylinders being electrically connected to the PLC controller.

[0007] Preferably, a connecting plate is fixed between several of the supporting cylinders, a fixing plate is fixed on the top surface of the connecting plate, a circular groove is formed on the top surface of the fixing plate, a column is fixed on the bottom surface of the supporting frame, the column is located in the middle of the supporting frame, and a ball is fixed at the bottom end of the column, the ball being rotatably disposed in the circular groove.

[0008] Preferably, the circular groove covers more than half of the sphere.

[0009] Preferably, each of the support cylinders has a suction cup fixed to its bottom end, and each of the suction cups has an air extraction pipe fixed to its outer side.

[0010] Preferably, each of the suction cups has a support frame fixed on all four sides of its outer wall, and the shape of each of the support frames is L-shaped.

[0011] Preferably, mounting seats are fixed on the front and right sides of the outer wall of the support frame, and a spirit level is fixed inside each of the two mounting seats.

[0012] Compared with existing technologies, the automatic leveling support structure for CNC machine tools that adopts the above technical solution has the following beneficial effects: 1. In use, through the coordinated action of the support frame, groove, dual-axis tilt sensor, support cylinder, cylinder, U-shaped seat, rotating hole, connecting block, rotating shaft and PLC controller, the automated leveling operation of the machine tool body is realized, which improves the leveling efficiency and accuracy, ensures that it can be in a horizontal state even on uneven ground, and improves the machining accuracy of the machine tool body. Second, during use, when the support frame is leveled, the ball can rotate freely within the circular groove, allowing the support frame to change angles more smoothly without excessive restriction or resistance, ensuring a smooth leveling process. Because the circular groove covers a large area of ​​the ball, it effectively restricts the ball's range of motion, preventing it from detaching from the groove due to external forces or its own inertia during rotation, thus ensuring the integrity and stability of the support structure. Activating the suction device removes air from the suction cup, creating a negative pressure environment. This negative pressure ensures the suction cup adheres tightly to the placement surface, further strengthening the connection between the support frame and the surface, thereby improving the stability of the support frame. Thirdly, during use, the L-shaped support frame can form a larger contact area with the placement surface, dispersing the pressure of the support frame on the placement surface and reducing deformation or damage to the placement surface caused by excessive local pressure. Furthermore, the L-shaped structure provides stable support in both horizontal and vertical directions, enhancing the connection stability between the suction cup and the placement surface and preventing the suction cup from sliding or loosening under external forces. The spirit level within the mounting base helps operators observe the levelness of the machine tool body. By observing the position of the bubble in the spirit level, it is possible to quickly determine whether the machine tool body is level. Even after automatic leveling, auxiliary checks can be performed at any time using the spirit level to ensure that the levelness of the machine tool body always meets the requirements.

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, an automatic leveling support structure for a CNC machine tool includes a support frame 1, which is fixed to the bottom surface of the machine tool body 2. A groove 3 is formed on the top surface of the support frame 1, and a dual-axis tilt sensor 4 is fixed inside the groove 3. The dual-axis tilt sensor 4 is located in the middle of the support frame 1. Several support cylinders 5 are provided below the support frame 1, and cylinders 6 are fixed inside each of the support cylinders 5. U-shaped seats 7 are fixed to the bottom surfaces of the four corners of the support frame 1. Rotating holes 8 are formed on the left and right sides of each of the U-shaped seats 7. Connecting blocks 9 are rotatably arranged inside each of the U-shaped seats 7, and the bottom surfaces of the connecting blocks 9 extend into each of the cylinders 6. One end of the telescopic rod is connected, and several connecting blocks 9 are fixed with rotating shafts 10 on the left and right sides. Both rotating shafts 10 are rotatably set in two rotating holes 8. A PLC controller 11 is fixed on the front side of the outer wall of the support frame 1. The PLC controller 11 is a Siemens S7-200. The dual-axis tilt sensor 4 and the cylinder 6 are electrically connected to the PLC controller 11. The PLC controller 11 is used to control the extension and retraction of the telescopic rod of the cylinder 6. Several cylinders 6 are equipped with air compressors. The air compressors are connected to the air inlet ports of two cylinders 6 through two high-pressure sealed air pipes, respectively, to provide synchronous air pressure power to drive the extension and retraction of the telescopic rod.

[0020] In use, the operator first fixes the machine tool body 2 to the top surface of the support frame 1, then places the entire assembly in the designated position. After activating the dual-axis tilt sensor 4, it can accurately measure the X and Y angle values ​​of the support frame 1 and quickly transmit the information to the PLC controller 11. After reading the X and Y angle values, the PLC controller 11 will precisely control the two cylinders 6 on the front or the two cylinders 6 on the rear to lower the connecting block 9 and the U-shaped seat 7, thereby reducing the front or rear of the support frame 1. If the Y angle value is positive, that is, the left or right side of the support frame 1 is higher, it will control the two cylinders 6 on the left or the two cylinders 6 on the right to lower the left or right side of the support frame 1. This adjustment is repeated until the absolute values ​​of the X and Y angles are both less than a set threshold, thus achieving automatic leveling of the support frame 1 and the machine tool body 2. After leveling is completed, the PLC controller 11 can stop the cylinders 6 and enter the holding state.

[0021] Through the coordinated action of support frame 1, groove 3, dual-axis tilt sensor 4, support cylinder 5, cylinder 6, U-shaped seat 7, rotating hole 8, connecting block 9, rotating shaft 10 and PLC controller 11, the automated leveling operation of machine tool body 2 is realized, which improves the leveling efficiency and accuracy, ensures that it can be in a horizontal state even on uneven ground, and improves the machining accuracy of machine tool body 2.

[0022] like Figures 1-4As shown, a connecting plate 12 is fixed between several support cylinders 5, a fixing plate 13 is fixed on the top surface of the connecting plate 12, a circular groove 14 is opened on the top surface of the fixing plate 13, a column 15 is fixed on the bottom surface of the support frame 1, the column 15 is located in the middle of the support frame 1, and a ball 16 is fixed at the bottom end of the column 15. The ball 16 is rotatably arranged in the circular groove 14.

[0023] In use, the connecting plate 12, the fixing plate 13, the support column 15 and the ball 16 together constitute the support system, which plays a good supporting role for the support frame 1 and effectively improves the stability of the overall structure. When the support frame 1 is adjusted horizontally, the ball 16 can rotate flexibly inside the circular groove 14, so that the support frame 1 can change the angle more smoothly during the adjustment process without being subject to too much restriction and resistance, thus ensuring the smooth progress of the leveling process.

[0024] like Figures 1-4 As shown, the circular groove 14 covers more than half of the sphere 16, and the bottom ends of several support cylinders 5 are all fixed with suction cups 17, and the outer sides of several suction cups 17 are all connected and fixed with air extraction pipes 18.

[0025] During use, when the support frame 1 undergoes various adjustments, the circular groove 14 effectively restricts the range of motion of the ball 16 due to its large coverage area. This prevents the ball 16 from detaching from the circular groove 14 during rotation due to external forces or its own inertia, ensuring the integrity and stability of the support structure. The suction cup 17 provides further support to the support frame 1. After connecting the air extraction pipe 18 to an external air extraction device and activating the device, the air inside the suction cup 17 is extracted, creating a negative pressure environment. This negative pressure allows the suction cup 17 to adhere tightly to the placement surface, further strengthening the connection between the support frame 1 and the placement surface, thereby improving the stability of the support frame 1.

[0026] like Figures 1-3 As shown, a number of suction cups 17 are fixed with support frames 19 on all four sides of their outer walls. The shape of the support frames 19 is L-shaped. Mounting seats 20 are fixed on the front and right sides of the outer walls of the support frame 1. A spirit level 21 is fixed inside each of the two mounting seats 20.

[0027] During use, the support frame 19 plays a crucial role in further increasing the supporting force and support area. The L-shaped support frame 19, on the one hand, allows for a larger contact area with the placement surface, dispersing the pressure of the support frame 1 on the placement surface and reducing deformation or damage to the placement surface caused by excessive local pressure; on the other hand, the L-shaped structure provides stable support in both horizontal and vertical directions, enhancing the connection stability between the suction cup 17 and the placement surface and preventing the suction cup 17 from sliding or loosening under external force. The bubble level 21 within the mounting base 20 helps operators observe the levelness of the machine tool body 2. By observing the position of the bubble in the bubble level 21, it is possible to quickly determine whether the machine tool body 2 is level. Even after automatic leveling, auxiliary checks can be performed at any time using the bubble level 21 to ensure that the levelness of the machine tool body 2 always meets the requirements.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
