Description

Technical Field

[0001] The utility model relates to the technical field of vertical lathes, in particular to a lubricating device for a vertical lathe. Background Art

[0002] Vertical lathes are large machine tools primarily used for machining heavy workpieces with large diameters and relatively short lengths. They are widely used in industries such as machinery manufacturing, energy, aerospace, and heavy equipment manufacturing, offering high machining precision and strong load-bearing capacity. Over long-term use, vertical lathes are prone to wear on column and crossbeam guides. Failure to lubricate these components can significantly shorten their service life.

[0003] The existing Chinese patent announcement CN220029570U discloses a CNC vertical lathe guide rail lubrication device. The device is fixed to the moving mechanism of the lathe through a mounting plate, and the smear pad is sleeved on the guide rail. The cylinder pushes the piston to move and pushes the lubricating oil in the push box into the smear pad. The fixed block moves with the movement of the moving mechanism of the lathe to evenly apply the lubricating oil on the guide rail. The distance between the two sets of fixed blocks can be flexibly adjusted by sliding the slide on the slide rod, which is convenient for lubricating different guide rails, and the height of the fixed block can be adjusted by cooperating with the vertical tube and the vertical rod.

[0004] However, in the above-mentioned prior art, the guide rails of the vertical lathe are usually designed with multiple rails arranged side by side. Lubrication of different guide rails is achieved by adjusting the distance between two sets of fixed blocks. This method can only lubricate and maintain one guide rail at a time, and the process is relatively cumbersome and inefficient.

[0005] Therefore, in order to solve such problems, we proposed a vertical lathe lubrication device. Utility Model Content

[0025] See also Figure 2 The upper surface of the connecting plate 51 is provided with a plurality of oil outlets 512 , which are matched with the oil outlet nozzles 52 . By setting the oil outlets 512 to match the oil outlet nozzles 52 , waste of lubricating oil during outflow is avoided.

[0026] See also Figure 3 The oil outlet nozzle 52 includes a sliding part 521 and an oil outlet pipe 522 threadedly connected to the center of the sliding part 521. The sliding part 521 matches the horizontal groove of the cross groove 511. A threaded groove 5221 is provided on the oil outlet pipe 522. Oil outlet holes 5222 are provided at both ends of the oil outlet pipe 522. The upper end of the oil outlet pipe 522 matches the oil outlet port 512. By twisting the oil outlet pipe 522, the oil outlet hole 5222 is docked with the oil outlet port 512, which facilitates the outflow of lubricating oil.

[0027] See also Figure 4 The oil tank 6 includes an outer shell 61 and a box bottom 62 welded to the lower end of the outer shell 61. The box bottom 62 is fixedly connected to the connecting plate 51. The upper end of the outer shell 61 is fixedly connected to a box cover 63. The box bottom 62 is set low on both sides and high in the middle. The setting of low sides and high in the middle facilitates the flow of lubricating oil to both sides, avoiding the problem of lubricating oil not being able to flow out smoothly when there is less lubricating oil.

[0028] See also Figure 5 Square grooves 621 are provided on both sides of the box bottom 62, and an adjusting piece 64 is movably connected in the square groove 621. One end of the adjusting piece 64 is fixedly connected to a control component 65, and one end of the control component 65 is fixedly connected to the connecting plate 51.

The driving end of the motor 652 is installed with a screw rod 653. The end of the screw rod 653 away from the motor 652 is threadedly connected to the connecting block 654. The connecting block 654 is fixedly connected to the adjusting piece 64. Turning on the motor 652 causes the screw rod 653 to rotate, and the connecting block 654 drives the adjusting piece 64 to move in the horizontal direction, thereby adjusting the size of the oil outlet 512 and controlling the oil output.

[0030] Working principle: By sliding the oil nozzle 52 along the cross groove 511, the oil nozzle 52 is pushed to different positions where the connecting plate 51 matches the guide rail 3, and the oil outlet 512 is adjusted to match the oil nozzle 52. Then, the motor 652 is rotated to turn on the screw rod 653, and the connecting block 654 drives the adjusting plate 64 to move in the horizontal direction, and the size of the oil outlet 512 is adjusted to control the oil output, so that the oil tank 6 moves with the slider 4 and can lubricate multiple guide rails 3.
