DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] Embodiment one: refer to Figures 1-3 As shown in the figure, a double-elasticity spindle comprises a spindle rod 2 which is elastically rotatably arranged in a rotating cavity of a spindle base 1.

[0026] A dirt cavity 4 is formed in the spindle base 1 below the rotating cavity, and the dirt cavity 4 is communicated with the rotating cavity through a through hole 3 in the spindle base 1. An oil hole is formed in the lower end of the spindle base 1 to communicate the outside of the spindle base 1 with the dirt cavity 4, and the oil hole is concentric with the through hole 3. Both the through hole 3 and the oil hole are taper holes, and the lower end surface of the dirt cavity 4 is a taper surface.

[0027] A plugging assembly is slidably arranged in the vertical direction in the dirt cavity 4, and a driving assembly is arranged at the lower end of the spindle base 1 to drive the plugging assembly to move in the vertical direction in the dirt cavity 4. The lower end of the plugging assembly plugs the oil hole when the spindle rod 2 is working, and the driving assembly drives the plugging assembly to move upward to plug the through hole 3, and then the oil hole is opened.

[0028] The plugging assembly comprises an upper plug 7, a lower plug 8 is concentrically arranged below the upper plug 7, the upper plug 7 and the lower plug 8 are fixedly connected through a plurality of vertical rods 6, the vertical rods 6 are slidably connected with limiting rods 5, and the limiting rods 5 are fixedly connected with the spindle base 1. Both the upper plug 7 and the lower plug 8 are made of rubber material.

[0029] The driving assembly comprises a discharge pipe 12 fixed at the lower end of the spindle base 1, the discharge pipe 12 is concentric with the oil hole, a rotating pipe 13 is concentrically rotatably arranged at the lower end of the discharge pipe 12, and an anti-skid pattern 14 is formed on the outside of the rotating pipe 13. A screw rod 10 is fixedly arranged in the rotating pipe 13. Specifically, a fixed rod 11 is fixed in the rotating pipe 13, and the screw rod 10 is fixedly connected with the fixed rod 11. The screw rod 10 is threadedly connected with a screw sleeve 9 fixed at the upper end of the lower plug 8 after penetrating through the lower plug 8.

[0030] The metal powder, particles and other impurities generated during the rotation of the spindle can enter the dirt cavity 4 through the through hole 3, and the metal powder, particles and other impurities can be stored in the dirt cavity 4.

[0031] Rotating the rotating tube 13, the rotating tube 13 drives the screw rod 10 to rotate through the fixed rod 11, since the screw rod 10 is threadedly connected with the screw sleeve 9, the screw sleeve 9 is fixed on the upper end of the lower plug 8, and the limiting rod 5 is slidingly connected with the vertical rod 6, thus, in the process of rotating the screw rod 10, the lower plug 8, the upper plug 7, the vertical rod 6 and the screw sleeve 9 go up, in the process of going up of the lower plug 8 in the oil hole, the lower plug 8 is gradually restored under the elastic action, and the lower plug 8 always seals the oil hole in the process of going up of the lower plug 8, the upper plug 7, the vertical rod 6 and the screw sleeve 9.

[0032] When the upper plug 7 seals the through hole 3, continuing to make the lower plug 8, the upper plug 7, the vertical rod 6 and the screw sleeve 9 go up, the lower plug 8 makes the oil hole open. At this time, the lubricating oil containing metal powder, particles and other impurities in the dirt cavity 4 can be discharged alone. Then, making the sealing assembly go down, the spindle 2 can continue to work after the oil hole is sealed by the lower plug 8.

[0033] Example two: on the basis of example one, referring to Figure 4 and Figure 5 The upper plug 7 is concentrically provided with an opening, an inner plug 15 is slidingly and pluggably arranged in the opening, and the inner plug 15 is made of rubber. An insertion rod 16 is fixedly arranged at the lower end of the inner plug 15 in a concentric manner, an insertion sleeve 17 is fixedly arranged at the upper end of the screw rod 10 in a concentric manner, the insertion sleeve 17 penetrates through a hole at the upper end of the screw sleeve 9, the insertion rod 16 is movably inserted into the insertion sleeve 17, an upper flange protruding inward is arranged at the upper end of the insertion sleeve 17, and a lower flange protruding outward is arranged at the lower end of the insertion rod 16, and the upper flange can block the lower flange.

[0034] In this embodiment, in the process of going up of the lower plug 8, the upper plug 7, the vertical rod 6 and the screw sleeve 9, the insertion rod 16 goes up in the insertion sleeve 17, and the inner plug 15 goes up with the upper plug 7. After the lubricating oil containing metal powder, particles and other impurities in the dirt cavity 4 is discharged alone, the sealing assembly continues to go up, and the inner plug 15 cannot continue to go up when the upper flange blocks the lower flange. Subsequently, with the continuous going up of the sealing assembly, the upper plug 7 is extruded in the through hole 3, and the inner plug 15 gradually exits from the upper plug 7. After the inner plug 15 exits from the upper plug 7, the lubricating oil in the rotating cavity can enter the dirt cavity 4 through the opening in the upper plug 7 and then be discharged through the oil hole, so that the lubricating oil in the rotating cavity can be conveniently discharged and replaced.

[0035] The above only describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
