[0020] Now, with reference to the accompanying drawings and preferred embodiments, the present invention will be further described in detail. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention.

[0021] As Figures 1 to 5 shown, a lubrication device for the main shaft of a punching machine provided by the present invention includes a base 1. A storage oil barrel 2 is fixedly connected to the top end of the base 1. A mixing rotating shaft 3 is movably connected to the inner cavity of the storage oil barrel 2. A spiral plate 4 is fixedly connected to the surface of the mixing rotating shaft 3. A driving mechanism 5 is arranged in the inner cavity of the base 1. A sealing rubber sleeve 6 is fixedly sleeved outside the spiral plate 4. An oil discharge cavity 8 is fixedly installed in the inner cavity of the base 1. The output end of the oil discharge cavity 8 is fixedly connected to a dispersion pipeline 9. The output end of the dispersion pipeline 9 is fixedly installed with a connecting joint 10.

[0022] Referring to Figures 1 to 5 , the driving mechanism 5 includes a driving motor 501, a driving gear 502, a transmission belt 503 and a transmission gear shaft 504. The driving motor 501 is fixedly installed at the rear side of the top of the base 1. The driving gear 502 is fixedly connected to the output end of the driving motor 501. The transmission belt 503 is movably sleeved on the surface of the driving gear 502. The transmission gear shaft 504 is movably sleeved inside the other end of the transmission belt 503. The driving gear 502, the transmission belt 503 and the transmission gear shaft 504 are all movably connected to the inner cavity of the base 1. The top end of the transmission gear shaft 504 penetrates to the bottom end of the inner cavity of the storage oil barrel 2. The top end of the transmission gear shaft 504 is movably connected to the bottom end of the mixing rotating shaft 3. The connecting joint 10 is fixedly installed at the left end of the rear side of the top of the base 1. The output end of the connecting joint 10 is connected to each oil inlet of the punching machine through a pipeline. The outer side of the sealing rubber sleeve 6 is fitted with the inner wall of the storage oil barrel 2. The top end of the storage oil barrel 2 is fixedly installed with a cylinder cover 7 through bolts. The top end of the mixing rotating shaft 3 is movably connected to the bottom end of the cylinder cover 7.

[0023] Adopt the above solution: The outer side of the sealing rubber sleeve 6 is attached to the inner wall of the oil storage barrel 2, so that during the rotation of the spiral plate 4, the sealing rubber sleeve 6 drives the oil adhered to the inner wall of the oil storage barrel 2 to be scraped off. Through the setting of the sealing rubber sleeve 6, it is possible to avoid direct contact between the spiral plate 4 and the inner wall of the oil storage barrel 2, resulting in wear. Through the setting of the cylinder cover 7, the mixing rotating shaft 3 and the spiral plate 4 can be disassembled, and it is convenient to inspect and maintain the inner cavity of the oil storage barrel 2.

[0024] Reference Figures 1 to 5 , a spiral cover 11 is threadedly connected to the top end of the cylinder cover 7, a bearing body 15 is fixedly sleeved on the surface of the top of the mixing rotating shaft 3, the surface of the bearing body 15 is fixedly sleeved inside the cylinder cover 7, an observation groove 12 is opened at the front end of the oil storage barrel 2, a scale is provided on the surface of the observation groove 12, and support feet 13 are fixedly connected to the four corners of the bottom end of the base 1. A maintenance cover plate 14 is fixedly installed at the bottom end of the base 1 through bolts, and a sealing gasket is provided at the connection between the maintenance cover plate 14 and the base 1.

[0025] Adopt the above solution: The oil is poured into the inner cavity of the oil storage barrel 2 through the spiral cover 11. Through the setting of the observation groove 12, it is convenient to observe the oil level in the inner cavity of the oil storage barrel 2. Through the setting of the support feet 13, the device can be supported, and it is possible to avoid wear caused by the bottom end of the base 1 contacting the ground. Through the setting of the maintenance cover plate 14, it is convenient to repair and replace the internal components of the base 1. Through the setting of the bearing body 15, the friction between the top of the mixing rotating shaft 3 and the cylinder cover 7 can be reduced, so that the device runs more stably and the wear at the connection between the mixing rotating shaft 3 and the cylinder cover 7 is also reduced.

[0026] Working principle:

[0027] During use, each component of this device is repaired and replaced through the PLC control panel. The output end of the connection joint 10 is connected to the oil inlet of the punching machine by using an oil delivery hose. The lubricating oil liquid is injected into the inner cavity of the oil storage barrel 2 by unscrewing the screw cap 11. The liquid level is observed through the observation slot 12 to control the injection amount of the oil liquid. The driving motor 501 is controlled to work to drive the driving gear 502 to rotate. The rotation of the driving gear 502 drives the transmission belt 503 to rotate. The rotation of the transmission belt 503 drives the transmission gear shaft 504 to rotate. The rotation of the transmission gear shaft 504 drives the mixing rotating shaft 3 to rotate. The rotation of the mixing rotating shaft 3 drives the spiral plate 4 to rotate. When the bottom end of the spiral plate 4 rotates to the output port of the oil storage barrel 2, a partial downward pressure is applied to the oil liquid, causing the oil liquid to be discharged from the output port of the oil storage barrel 2 to the dispersion pipeline 9, transported through the dispersion pipeline 9 to the connection joint 10 for shunting, and the oil liquid is transported to positions such as the main shaft of the punching machine by the oil delivery hose. When the oil liquid transportation is completed, since the oil circuit is filled with oil liquid everywhere, the oil liquid no longer discharges from the output port of the oil storage barrel 2, and the downward pressure generated at the bottom of the spiral plate 4 is not sufficient to cause the oil circuit to expand and be damaged. During normal use, the oil liquid is continuously pressurized by the rotation of the spiral plate 4, so that the pressure of the lubricating oil liquid is stable, and at the same time, the oil liquid will not produce precipitation and other phenomena due to long-term stillness. And when replacing the oil liquid, the rotation of the spiral plate 4 drives the sealing rubber sleeve 6 to scrape off the oil liquid adhering to the inner wall of the oil storage barrel 2, so that the waste oil liquid can be completely discharged.

[0028] In summary, through the coordinated operation of each component, this lubricating device for the main shaft of the punching machine solves the problems that in the actual use process of existing equipment, the oil liquid is mostly static in the fuel tank, which will cause oil liquid precipitation and reduce the effectiveness, and when replacing the oil liquid, the oil liquid adhering to the inner wall of the fuel tank cannot be completely discharged, resulting in a reduction in the quality of the new oil liquid.
