Technical Field

[0001] The utility model relates to the field of reduction gear boxes, in particular to a metal product rotary reduction gear box for machine tools. Background Art

[0002] Patent No. CN211231457U discloses a multi-rotation reduction gearbox structure. The utility model has a reasonable structural design. The device uses a gear plate to drive the rotation of the shaft rod, and at the same time realizes the coordinated rotation of the third bevel gear and the second bevel gear through the shaft rod, thereby realizing the rotation of the horizontal axis, thereby realizing the selection of two deceleration effects and improving the deceleration efficiency.

[0003] However, the above-mentioned existing multi-rotation reduction box structure, although the device is provided with two different reduction methods, is prone to damage due to frequent use between gears, and has to temporarily stop working and use another set of reduction structure to replace it. During this process, it is easy to affect the normal work efficiency of the staff.

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] refer to Figure 1-4The utility model provides a technical solution: a metal product rotary reduction box for machine tools, comprising a reduction box body 1, threaded holes 4 are opened on both sides of the reduction box body 1, and threaded rods 3 are threadedly connected in the threaded holes 4. By setting the threaded holes 4 and the threaded rods 3, when the threaded rods 3 are inserted into the threaded holes 4, the installation of the cover plate 2 is realized, and the surface of the threaded rods 3 is threadedly connected to the cover plate 2 at the same time, and the lower end surface of the cover plate 2 is fixedly connected to a motor 5. By setting the motor 5, the rotation of the vertical shaft 6 is controlled. The output end of the motor 5 is installed with a vertical shaft 6, and the surface of the vertical shaft 6 is fixedly sleeved with a first gear 7, and the surface of the first gear 7 is meshedly connected with three second gears 12 at the same time. By setting the first gear 7 and the second gear 12, when the first gear 7 rotates, the second gear 12 is transmitted, and the front faces of the three second gears 12 are fixedly connected with pinions 11. A support rod 9 is fixedly connected in the reduction box body 1, and a third gear 8 is rotatably sleeved on the surface of the support rod 9.

[0022] The inner wall of the cover plate 2 is sleeved on the surface of the reduction box body 1 .

[0023] Among them, the surface of the threaded rod 3 is threadedly connected with a nut 15. By setting the nut 15, when the nut 15 is pressed against the surface of the cover plate 2, the threaded rod 3 is limited, so that the threaded rod 3 is more stable during installation, and one side of the nut 15 presses against the surface of the cover plate 2.

[0024] The surface of the pinion gear 11 is meshedly connected with the ring gear 10 . By providing the ring gear 10 , when the pinion gear 11 rotates, it rotates on the inner wall of the ring gear 10 .

[0025] The surface of the ring gear 10 is fixedly connected inside the reduction gearbox body 1 .

[0026] The vertical shaft 6 passes through the upper end surface of the reduction box body 1 .

[0027] The working principle of the utility model, embodiment 1: when the motor 5 is running, the vertical shaft 6 is controlled to rotate, so that the first gear 7 rotates synchronously. During the rotation, the first gear plate drives the second gear 12, and the second gear plate synchronously drives the pinion 11, so that the pinion 11 rotates in the ring gear 10, thereby achieving an effective deceleration effect.

[0028] Example 2: Reference Figure 2 When the threaded rod 3 is pushed into the reduction box body 1, there is a spare threaded hole 4. When speed regulation is required, the threaded rod 3 is pushed into another threaded hole 4 to make the first gear 7 mesh with the second gear 12. Figure 4 Since the third gear 8 and the second gear 12 are arranged in different sizes, the deceleration speed is also different to a certain extent, so that the speed can be adjusted when the device is used.

[0029] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and utility model concept of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
