[0002] Vertical CNC lathe is a vertical lathe controlled by CNC technology. It has the characteristics of high degree of automation, high processing precision and high production efficiency. The multi-axis linkage synchronous control of the vertical CNC lathe can ensure that multiple shafts can work together to achieve high-speed and high-precision processing requirements. The goal of synchronous control is to keep a certain synchronous operation relationship between the axes to ensure the accuracy and efficiency of the processing process.

[0003] At present, the longitudinal running rods of vertical CNC machine tools can drive dual axes or multiple axes to start simultaneously through the meshing of synchronous chains and gears, thereby improving the processing effect of parts. However, after long-term use of vertical CNC machine tools, the synchronous chains have not been lubricated and maintained for a long time, and the oil film will gradually decrease, resulting in oil shortage in the chain, which will increase the friction and affect the transmission efficiency of the synchronous chain. This will affect the performance of the vertical CNC machine tools to a certain extent, resulting in the longitudinal running axis running smoothly. In view of this, we propose a multi-axis linkage synchronous control mechanism for vertical CNC lathes. Utility Model Content

[0024] At present, the longitudinal running rods of vertical CNC machine tools can drive dual axes or multiple axes to start simultaneously through the meshing of synchronous chains and gears, thereby improving the processing effect of parts. However, after long-term use of vertical CNC machine tools, the synchronous chains have not been lubricated and maintained for a long time, and the oil film will gradually decrease, causing the chain to lack oil, which will increase friction and affect the transmission efficiency of the synchronous chain. This will affect the performance of the vertical CNC machine tools to a certain extent, resulting in the longitudinal running axis running smoothly.

[0025] See also Figure 1-Figure 5As shown, the device includes a control panel body 1, which is installed on the surface of a connecting rod 12, and the connecting rod 12 is located on the surface of a machine tool frame 13. Two operating shafts 11 are movably installed inside the control panel body 1. A control component cover 14 is installed on the top of the control panel body 1. The control component cover 14 is formed by splicing a fixed cover 141 and a movable cover 142. Running gears 15 are installed on the tops of the two operating shafts 11, and the running gears 15 are located inside the control component cover 14. A running chain 16 is meshed and connected between the two running gears 15, and the top of one of the running gears 15 is fixedly connected to the output shaft of a motor 17. The motor 17 is installed on the top of the control component cover 14, and a lubrication component 2 for auxiliary storage of lubricating oil is slidably installed inside the fixed cover 141, and the other end of the lubrication component 2 is connected to the oil immersion component 3.

[0026] First, the specific structure of the lubrication assembly 2 is disclosed. The lubrication assembly 2 includes a mounting plate 21 slidably mounted on the upper end of the inner wall of the fixed cover 141. The bottom of the mounting plate 21 is fixedly connected to an oil tank 22. A connecting hole 24 is provided on the lower end surface of the oil tank 22. An extension rod 23 for conveying lubricating oil is installed inside the connecting hole 24. The extension rod 23 is a hollow structure. The mounting plate 21 slidably mounted inside the fixed cover 141 allows the oil tank 22 to be movably mounted inside the control cover 14, which is convenient for adding lubricating oil. The connecting hole 24 provided on the lower end surface of the oil tank 22 and the extension rod 23 installed inside the connecting hole 24 facilitate conveying and lubricating the lubricating oil inside the oil tank 22.

[0027] Next, the specific structure of the oil immersion component 3 is disclosed. The oil immersion component 3 includes a movable plate 31 rotatably mounted on the other end of the extension rod 23. The interior of the movable plate 31 is a hollow structure. A plurality of oil rods 32 are mounted on the outer wall of the movable plate 31. A brush head 33 is mounted on the other side of each of the plurality of oil rods 32, and the outer wall of the brush head 33 is in contact with the surface of the running chain 16. The extension rod 23 can be used to deliver lubricating oil to the interior of the hollow movable plate 31. As the running chain 16 is started, the brush head 33 can be pulled to rotate, so that the movable plate 31 rotates inside the extension rod 23, which improves the fluidity of the lubricating oil. The lubrication of the running chain 16 by the plurality of brush heads 33 effectively improves the running smoothness of the running chain 16, and improves the synchronization effect of the running shaft 11 to a certain extent.

[0028] The improvement of this embodiment lies in that: first, through the connecting rod 12, the control panel body 1 can be installed on the surface of the machine tool frame 13, and the motor 17 is used to drive the running gear 15 and the running chain 16 to start, so that the two running shafts 11 can be synchronously linked, and the mounting plate 21 installed inside the fixed cover 141 is slidably installed, so that the oil tank 22 can be movably installed inside the control component cover 14, which is convenient for adding lubricating oil, and the connecting hole 24 opened on the lower end surface of the oil tank 22 and the extension rod 23 installed inside the connecting hole 24 are used to facilitate the transportation and lubrication of the lubricating oil inside the oil tank 22. With the start of the running chain 16, the brush head 33 can be pulled to rotate, so that the movable plate 31 rotates inside the extension rod 23, which improves the fluidity of the lubricating oil. The lubrication of the running chain 16 by a plurality of brush heads 33 effectively improves the running smoothness of the running chain 16, and to a certain extent improves the synchronization effect of the running shaft 11.

[0029] Considering the effect of the lubricating oil in the oil tank 22 entering the movable plate 31, in order to facilitate the lubricating oil to enter the movable plate 31, Figure 4 As shown, the extension rod 23 is in a state of being inclined toward the movable plate 31 side.

[0030] The improvement lies in that the extension rod 23 is tilted toward one side of the movable plate 31 to facilitate the lubricating oil in the auxiliary oil tank 22 to flow into the movable plate 31 , thereby effectively improving the oil discharge effect of the lubricating oil.

[0031] Since the interior of the movable plate 31 is a hollow structure and a plurality of oil rods 32 are connected to its surface, in order to reduce the situation where too much lubricating oil enters the oil rods 32 and the brush head 33 at one time, Figure 4-Figure 5 As shown, an oil-soaked cotton block 4 for auxiliary storage of lubricating oil is provided inside the movable plate 31 .

[0032] The improvement lies in that: by using the oil-soaked cotton block 4 installed inside the movable plate 31, the lubricating oil inside the movable plate 31 can be auxiliary stored, effectively reducing the situation where the lubricating oil directly enters the oil rod 32, and lubricating the surface of the running chain 16 through the brush head 33, reducing the waste of lubricating oil.

[0033] In summary, the working principle of this scheme is as follows: first, the control panel body 1 can be installed on the surface of the machine tool frame 13 through the connecting rod 12, and the motor 17 is used to drive the running gear 15 and the running chain 16 to start, so that the two running shafts 11 can be synchronously linked, and the mounting plate 21 installed inside the fixed cover 141 is slidably installed, so that the oil tank 22 can be movably installed inside the control component cover 14, which is convenient for adding lubricating oil, and the connecting hole 24 opened on the lower end surface of the oil tank 22 and the extension rod 23 installed inside the connecting hole 24 are used to facilitate the transportation and lubrication of the lubricating oil inside the oil tank 22. When the running chain 16 is started, the brush head 33 can be pulled to rotate, so that the movable plate 31 can be rotated inside the extension rod 23, which improves the fluidity of the lubricating oil. The lubrication of the running chain 16 by a plurality of brush heads 33 effectively improves the running smoothness of the running chain 16, and to a certain extent improves the synchronization effect of the running shaft 11. The oil-soaked cotton block 4 installed inside the movable plate 31 can be used to assist in the storage of the lubricating oil inside the movable plate 31, which effectively reduces the situation where the lubricating oil directly enters the oil rod 32. The surface of the running chain 16 is lubricated by the brush head 33, which reduces the waste of lubricating oil.
