Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled gantry machine tools, and in particular to a numerically controlled gantry crossbeam. Background Art

[0002] The CNC gantry beam is an important part of the CNC gantry milling machine. Its main function is to support the workbench, spindle box and other components to ensure the stability and processing accuracy of the machine tool. The beam is usually made of cast iron, welding or assembly process, and has the characteristics of high strength and good rigidity. The design and manufacturing quality of the beam are directly related to the performance and processing efficiency of the machine tool. Common beam structures include fixed and adjustable types.

[0003] The CNC gantry beam in the prior art generally needs to be provided with a guide rail on its top so that the support plate can move back and forth smoothly on the top of the CNC gantry beam. The long-term back and forth movement of the support plate on the surface of the guide rail will cause the surface of the guide rail to be easily worn. However, since the CNC gantry machine tool is generally large in size, the height of the CNC gantry beam is high, and it is difficult to manually lubricate and maintain the guide rail on the top of the CNC gantry beam, which will reduce the service life of the guide rail on the top of the CNC gantry beam, and further have an adverse effect on the use of the CNC gantry machine tool. Summary of the invention

[0035] As a technical optimization solution of the present invention, a plurality of connecting plates 7 are installed at the bottom end of the storage box 6, and the plurality of connecting plates 7 are all threadedly connected to the support plate 5 through preset bolts. The storage box 6 can be installed on the top of the support plate 5 by sequentially passing through the holes opened inside the plurality of connecting plates 7 and threadedly connected to the threaded holes pre-opened on the outer walls of both sides of the support plate 5. Since there is a space reserved inside the storage box 6 for facilitating the up and down movement of the spindle housing 4, after the storage box 6 is installed on the top of the support plate 5, it will not hinder the use of the spindle housing 4.

[0036] As a technical optimization solution of the present invention, the top and one side outer wall of the storage box 6 are respectively provided with an oil inlet 10 and a sewage outlet 11, and a sealing plug 15 is installed at the end of the oil inlet 10 and the sewage outlet 11 away from the storage box 6. By opening the sealing plug 15 of the oil inlet 10, lubricating oil can be added to the inside of the storage box 6; by opening the sealing plug 15 of the sewage outlet 11, the oil dirt inside the storage box 6 can be discharged to the outside.

[0037] As a technical optimization scheme of the present invention, the lubrication mechanism includes two first grooves 20 opened on the outer wall of the fixed plate 8 away from the storage box 6, the first screw rods 21 are rotatably installed inside the two first grooves 20, the outer walls of the two first screw rods 21 are threadedly installed with sliding blocks 26, the ends of the two sliding blocks 26 away from the first screw rods 21 are installed with fixed seats 22, and the rotating blocks 27 are rotatably installed inside the two fixed seats 22. Two first drive motors are preset inside the fixed plate 8, and the output ends of the two first drive motors are respectively connected to one end of the two first screw rods 21, so as to drive the two first screw rods 21 to rotate inside the corresponding first grooves 20, and drive the sliding blocks 26 set on the outer walls to move back and forth inside the first grooves 20; second drive motors are preset on the outer walls of one side of the two fixed seats 22, and the output ends of the two second drive motors are respectively connected to the rotating parts of the two rotating blocks 27, so as to drive the two rotating blocks 27 to rotate and adjust inside the corresponding fixed seats 22.

[0038] As a technical optimization solution of the present invention, the bottom ends of the two rotating blocks 27 are connected to the mounting plates 24 through the electric telescopic rods 23, and the bottoms of the two mounting plates 24 are installed with rubber pads 28. During the telescopic process, the telescopic ends of the two electric telescopic rods 23 can drive the two mounting plates 24 and the rubber pads 28 to move up and down together.

[0039] As a technical optimization scheme of the present invention, rotating plates 25 are rotatably installed at both ends of the two mounting plates 24, two second grooves 30 are provided at the bottom ends of the two rotating plates 25, second screw rods 33 are rotatably installed inside the two second grooves 30, moving blocks are threadedly installed on the outer walls of the two second screw rods 33, and moving plates 9 are installed at the bottom ends of the two moving blocks. Two third driving motors are preset on the outer walls of one side of the two mounting plates 24, and the output ends of the two third driving motors are respectively connected to the rotating parts of the two rotating plates 25, so as to drive the two rotating plates 25 to rotate and adjust at both ends of the mounting plates 24; first driving devices are preset on the outer walls of both sides of the two rotating plates 25, and the output ends of the two first driving devices are respectively connected to one end of the two second screw rods 33, so as to drive the two second screw rods 33 to rotate inside the corresponding second grooves 30, and drive the two moving blocks and the moving plate 9 to move and adjust inside the rotating plate 25.

[0040] As a technical optimization scheme of the present invention, a first soft pad 29 is installed at the bottom end of the two rotating plates 25 between the two second grooves 30, and a second soft pad 34 is installed on the outer wall on the side where the two movable plates 9 are close to each other. A circular hole 31 is opened inside the first soft pad 29 at the bottom of one rotating plate 25 and the second soft pad 34 on the side where the two movable plates 9 are close to each other, and laser displacement sensors 32 are installed inside the multiple circular holes 31. After the two movable plates 9 move to the minimum distance in the direction of approaching each other, the two second soft pads 34 are in contact with the two ends of the first soft pad 29. At this time, the two second soft pads 34 and the first soft pad 29 are in contact with the outer wall of the first guide rail 2. As the support plate 5 moves back and forth on the top of the two crossbeam bodies 1, the two second soft pads 34 and the first soft pad 29 can be driven to automatically clean the outer wall of the first guide rail 2; and while the two movable plates 9 and the rotating plate 25 move on the surface of the first guide rail 2, the straightness of the first guide rail 2 can be automatically detected with the help of the multiple laser displacement sensors 32, and when the first guide rail 2 is aged and deformed, the deformation of the first guide rail 2 will be provided to the staff in the first time by way of an alarm to avoid damage caused by continued operation of the equipment; the laser displacement sensor 32 is a ZLDS10X series laser displacement sensor that is only available in the UK in the prior art, which can provide high-precision and high-resolution measurement results, and the error range is usually at the micron level, which is crucial to ensuring the safety of the first guide rail 2. In addition, since the multiple laser displacement sensors 32 are arranged inside the corresponding first soft pad 29 and the second soft pad 34, the multiple laser displacement sensors 32 can achieve non-contact measurement, avoiding the wear or damage to the first guide rail 2 that may be caused by mechanical contact, and have the ability of high-speed real-time measurement, and can perform dynamic monitoring during the operation of the equipment, thereby improving the detection efficiency and accuracy; in this embodiment, the rotating plate 25 and the two movable plates 9 close to the storage box 6 are both hollow, and the rotating plate 25 and the two movable plates 9 are connected to the storage box 6 through a preset hose and an oil pump, so that after the oil pump is started, the lubricating oil inside the storage box 6 can be extracted and transported to the corresponding rotating plate 25 and the two movable plates 9, and Oil outlets are pre-opened on the outer walls of the rotating plate 25 and the two movable plates 9 on one side close to the first soft pad 29 and the second soft pad 34. The lubricating oil entering the rotating plate 25 and the two movable plates 9 can be adsorbed and collected by the first soft pad 29 and the second soft pad 34 through the oil outlets, and in the subsequent contact with the outer wall of the first guide rail 2, the outer wall of the first guide rail 2 can be automatically lubricated, so that the support plate 5 can move back and forth on the top of the two first guide rails 2; the two second guide rails 35 and other guide rails inside the equipment can also be conveniently added with oil pumps, hoses and other components on the outside of the storage box 6, so that the lubricating oil inside the storage box 6 can be extracted and accurately discharged to the two second guide rails 35 and other guide rail surfaces, which also has an automatic lubrication effect on other guide rails.

[0041] As a technical optimization solution of the present invention, the cleaning mechanism includes a moving frame 13, which is slidably installed inside the storage box 6. Two sets of connecting rods 14 are installed on the top of the moving frame 13. The top ends of the two sets of connecting rods 14 pass through the storage box 6 and are connected to the fixed frame 12. By pulling the fixed frame 12 up and down at the top of the storage box 6, the moving frame 13 can be driven to move up and down together inside the storage box 6 with the help of the connecting rods 14.

[0042] As a technical optimization solution of the present invention, a mounting groove 18 is provided inside the mobile frame 13, and an electric heating plate 19 is installed inside the mounting groove 18. After the electric heating plate 19 is powered on to generate heat, it can heat the lubricating oil inside the storage box 6.

[0043] As a technical optimization solution of the present invention, a plurality of through grooves 16 are provided inside the movable frame 13, a guide groove 17 is provided at the top of the movable frame 13 and directly below the oil inlet valve 10, and notches are provided at both ends of the movable frame 13 near the guide groove 17. By providing a plurality of through grooves 16 inside the movable frame 13, it is ensured that the movable frame 13 moves up and down smoothly inside the storage box 6, and the lubricating oil is prevented from moving inside the storage box 6 together; the outer wall of the movable frame 13 abuts against the inner wall of the storage box 6, so that the movable frame 13 can scrape and clean the inner wall of the storage box 6 up and down during the up and down movement.

[0044] In the present invention, when the user uses the device, he first opens the sealing plug 15 of the oil inlet 10 and adds a sufficient amount of lubricating oil to the inside of the storage box 6. When the first guide rails 2 at the top of the two crossbeam bodies 1 need to be lubricated, the two first screw rods 21 inside the two fixed plates 8 can be controlled to rotate together, driving the corresponding two sliding blocks 26 to move in a direction of approaching each other, until the two mounting plates 24 move to the top of the corresponding first guide rails 2, and then the rotating plate 25 at one end of the mounting plate 24 away from the storage box 6 is controlled to rotate upward 90 degrees to a vertical state, so that the rotating plate 25 and the two movable plates 9 will not contact the first guide rails 2 in the future, and the extension and retraction of the multiple electric telescopic rods 23 can be controlled. The two ends extend downward together, driving the mounting plate 24 and the rotating plate 25 near one end of the storage box 6 to move downward together, until the two movable plates 9 at the bottom end of the rotating plate 25 are respectively located on both sides of the first guide rail 2, and the two movable plates 9 are controlled to move in a direction close to each other, driving the two second soft pads 34 and the first soft pad 29 to abut against the outer wall of the first guide rail 2. At this time, as the support plate 5 moves back and forth on the top of the two crossbeam bodies 1, the lubricating oil adsorbed inside the two second soft pads 34 and the first soft pad 29 can be smeared on the outer wall of the first guide rail 2, thereby achieving the effect of automatic lubrication of the first guide rail 2, and facilitating the smooth back and forth movement of the support plate 5 on the top of the two first guide rails 2.

[0045] At the same time, in order to avoid the presence of dust and other impurities on the surfaces of the two first guide rails 2 when lubricating the surfaces of the two first guide rails 2, which would have an adverse effect on the subsequent lubrication, before lubricating the surfaces of the first guide rails 2 with the help of the first soft pad 29 and the two second soft pads 34 at one end of the mounting plate 24 close to the storage box 6, the rotating plate 25 and the two moving plates 9 at one end of the mounting plate 24 close to the storage box 6 are first controlled to rotate upward together to a vertical state. At this time, as the telescopic end of the electric telescopic rod 23 extends downward, the mounting plate 24 and the second soft pads 34 away from the storage box 6 can be driven to rotate upward together to form a vertical state. The rotating plate 25 and the two movable plates 9 at one end of the storage box 6 move downward to be close to the first guide rail 2, and the first soft pad 29 and the two second soft pads 34 arranged on the outer walls of the rotating plate 25 and the two movable plates 9 will contact the first guide rail 2. As the support plate 5 moves back and forth, the corresponding first soft pad 29 and the two second soft pads 34 can clean and remove dust and other impurities on the surface of the first guide rail 2, reducing the negative impact of dust and other impurities on the subsequent lubrication of the surface of the first guide rail 2, thereby improving the quality of lubrication of the surfaces of the two first guide rails 2.

[0046] Furthermore, when the rotating plate 25 and the two movable plates 9 at one end of the mounting plate 24 away from the storage box 6 are moved to a position close to the first guide rail 2, the straightness of the first guide rail 2 can be automatically detected by means of the laser displacement sensor 32 installed inside the first soft pad 29 and the two second soft pads 34, and when the first guide rail 2 is aging and deformed, the deformation of the first guide rail 2 will be provided to the staff in the first time by way of an alarm to avoid damage caused by continued operation of the equipment;

[0047] Moreover, when the laser displacement sensor 32 detects deformation at a certain position of the first guide rail 2, the relevant detection data can be transmitted to the preset controller, and the controller can control multiple first screw rods 21 to rotate together, thereby driving the two sliding blocks 26 to move in opposite directions inside the corresponding first grooves 20, and after driving multiple mounting plates 24 to move to a position away from the first guide rail 2, the rotating plates 25 at both ends of the multiple mounting plates 24 are controlled to rotate upward to a vertical state, and then the telescopic ends of the multiple electric telescopic rods 23 are controlled to extend downward together, driving the rubber pads 28 at the bottom ends of the multiple mounting plates 24 to tightly abut against the top ends of the two crossbeam bodies 1, so as to have a limiting and fixing effect on multiple components such as the pallet 5, thereby preventing the pallet 5 from continuing to move on the deformed first guide rail 2, resulting in unstable movement and greater wear of components such as the pallet 5, and indirectly having a protective effect on components such as the pallet 5.

[0048] When lubricating oil is needed to lubricate the surfaces of the two first guide rails 2 in winter, if the fluidity of the lubricating oil inside the storage box 6 is poor at this time, the electric heating plate 19 inside the movable frame 13 can be controlled to be powered on and started, so that the electric heating plate 19 generates heat after being powered on, and the lubricating oil inside the storage box 6 can be heated to improve the fluidity of the lubricating oil inside the storage box 6, ensuring that the lubricating oil can be used normally in winter;

[0049] During the process of heating the lubricating oil by the electric heating plate 19, the multiple rotating blocks 27 can be controlled to rotate 180 degrees upward inside the corresponding fixed seat 22, so that the multiple mounting plates 24 and other components can be rotated together to the top of the fixed seat 22, and the multiple first screw rods 21 can be controlled to drive the corresponding sliding blocks 26 to adjust the position, so that the multiple mounting plates 24 are respectively located directly below the two fixed frames 12. At this time, by controlling the telescopic ends of the multiple electric telescopic rods 23 to extend and retract upward, the multiple mounting plates 24 can be driven to move up and down together with the two fixed frames 12. With the help of the multiple connecting rods 14, the movable frame 13 can be driven to move up and down slowly inside the storage box 6 synchronously, driving the electric heating plate 19 to comprehensively heat the lubricating oil inside the storage box 6, ensuring that the lubricating oil inside the storage box 6 is heated more evenly, which can ensure that the lubricating oil has better fluidity inside the storage box 6.

[0050] After the lubricating oil in the storage box 6 is used up, when new lubricating oil needs to be added to the storage box 6, the multiple rotating blocks 27 can be controlled to rotate 180 degrees upward inside the corresponding fixed seat 22, so that the multiple mounting plates 24 are located below the two fixed frames 12, and the telescopic ends of the multiple electric telescopic rods 23 are extended upward to push the two fixed frames 12 to move upward, driving the movable frame 13 to move upward to the top inside the storage box 6. At this time, the guide groove 17 opened on the top of the movable frame 13 is located below the oil inlet 10. At this time, the lubricating oil entering the storage box 6 through the oil inlet door 10 will first fall into the inside of the guide groove 17, and be discharged through the notches at both ends of the guide groove 17 to contact the inner wall of the storage box 6, so that the lubricating oil will slowly flow downward along the inner wall of the storage box 6, so as to reduce the problem that the lubricating oil directly falls downward into the storage box 6 during the process of adding new lubricating oil, causing the lubricating oil to be hit, and there are a large number of bubbles inside and on the surface of the lubricating oil, which affects the subsequent use of the lubricating oil.

[0051] If the lubricating oil entering the storage box 6 is diverted and transported in the above-mentioned manner, there are still a small amount of bubbles inside and on the surface of the lubricating oil. At this time, the electric heating plate 19 can be controlled to be powered on to heat the lubricating oil entering the storage box 6. After the lubricating oil is heated to an appropriate temperature, it can help to reduce the viscosity of the lubricating oil, allowing the bubbles inside the lubricating oil to escape to the surface more easily. After the lubricating oil is heated for a period of time, the foam on the surface of the lubricating oil will naturally disappear, thereby facilitating the subsequent use of the lubricating oil in the storage box 6.

[0052] After the storage box 6 has been used for a period of time, oil stains will inevitably be generated inside the storage box 6. Before adding new lubricating oil, the oil stains inside the storage box 6 need to be cleaned and the inside of the storage box 6 cleaned. At this time, the sealing plug 15 of the drain port 11 can be opened to cause the oil stains inside the storage box 6 to be discharged first, and then the sealing plug 15 is reset, and water or other liquid mixed with a cleaning agent is added to the inside of the storage box 6 through the oil inlet 10, and again with the help of multiple rotating blocks 27 that rotate 180 degrees upward, the multiple mounting plates 24 are driven to rotate to two fixed positions respectively. The movable rack 13 is located below the storage box 6, and with the help of the repeated extension and retraction of the telescopic ends of the multiple electric telescopic rods 23, the multiple mounting plates 24 are driven to push the two fixed racks 12 upward and reset downward, so that the movable rack 13 is located inside the storage box 6 and moves up and down together, which has an auxiliary scraping effect on the inner wall of the storage box 6, and can simultaneously have an up and down stirring effect on the liquid injected into the storage box 6, so that the cleaning agent can be better mixed with the oil inside the storage box 6, so that the movable rack 13 can have an automatic cleaning effect on the inside of the storage box 6, which is convenient for improving the cleaning efficiency of the inside of the storage box 6.

Obviously, many modifications and changes can be made according to the content of this specification.
