[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: a single-top crown guide mechanism of a press machine, including a workbench 1, which can support objects for extrusion. The upper end of the workbench 1 is fixedly connected to an upper crossbeam 2, which can support a pressure assembly. The middle of the upper crossbeam 2 is fixedly connected to a pressure assembly, and the pressure assembly includes a driving device 4. The driving device 4 can drive a slider 6 to slide up and down to provide pressure. The lower part of the driving device 4 is fixedly connected to a slider 6, and the slider 6 can be extruded when in contact with an object. The two ends of the slider 6 are internally slidably connected with guide rails 3, and the guide rails 3 can support the slider 6 to keep it sliding vertically and linearly. The upper part of the driving device 4 is fixedly connected to the upper end of the upper crossbeam 2, and the upper crossbeam 2 keeps the driving device 4 relatively fixed. The upper and lower parts of the guide rails 3 are respectively fixedly connected to the inside of the upper crossbeam 2 and the inside of the upper end of the workbench 1, and the guide rails 3 are restricted to remain vertically fixed.

[0032] Reference Figure 1-Figure 3The top of the workbench 1 is rotatably connected with a positioning rod 7, and the upper part of the positioning rod 7 is slidably connected to the inside of the two ends of the slider 6. The positioning rod 7 can support the slider 6 to keep it stable when sliding and keep the position accurate. The lower part of the upper beam 2 is slidably connected with a T-block 9, and the T-block 9 can make the oil storage box 5 only slide horizontally and linearly relative to the upper beam 2. The internal sliding connection of the T-block 9 is a clamping component, and the lower part of the T-block 9 is fixedly connected with an oil storage box 5. Lubricating oil can be stored in the oil storage box 5 for easy lubrication. The lower end of the oil storage box 5 is elastically connected to an extrusion rod 12 through a spring 11. The extrusion rod 12 is L-shaped and can be squeezed The pressure drives the oil outlet 10 to slide upward so that the lubricating oil can flow out to lubricate the limit rod. One end of the spring 11 is fixedly connected to the lower end of the oil storage box 5, and the other end of the spring 11 is fixedly connected to the inside of the extrusion rod 12. The extrusion of the spring 11 can keep the extrusion rod 12 fixed and unable to slide relative to the oil storage box 5. The upper part of the extrusion rod 12 is fixedly connected with the oil outlet 10. The oil outlet 10 is cylindrical and has a square groove on the side end to allow the lubricating oil to slide out. This does not require the machine to be shut down, which improves work efficiency. The outside of the oil outlet 10 and the upper part of the extrusion rod 12 are both slidably connected to the lower end of the oil storage box 5.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The clamping assembly includes a sliding handle 8, which can drive the inclined surface block 13 to slide horizontally. The side of the sliding handle 8 is slidably connected to the inside of the side end of the upper beam 2. The side end of the sliding handle 8 is fixedly connected with the inclined surface block 13. The inclined surface of the side end of the inclined surface block 13 squeezes the clamping block 14 to slide up, and the limit is released to slide the T-shaped block 9 out. The outside of the inclined surface block 13 is slidably connected to the inside of the upper end of the upper beam 2. The upper beam 2 limits the inclined surface block 13 to slide linearly within a fixed distance. The side of the inclined surface block 13 contacts the clamping block 14, and the side end of the clamping block 14 is a square groove. So that the inclined plane block 13 can slide in, and the inclined plane block 13 can limit the block 14 so that it cannot slide down and out of the upper beam 2. The upper part of the block 14 is elastically connected to the upper end of the upper beam 2 through the second spring 15. The second spring 15 can squeeze the block 14 to keep it fixed inside the T-block 9. The lower part of the block 14 is slidably connected to the upper end of the T-block 9. One end of the second spring 15 is fixedly connected to the upper end of the upper beam 2. The second spring 15 can squeeze the block 14 to slide down, and the other end of the second spring 15 is fixedly connected to the upper part of the block 14.

[0034] Working principle: The driving device 4 can drive the lower end slider 6 to slide up and down. The slider 6 is restricted by the guide rail 3 and the positioning rod 7 to keep it vertical and stable when sliding up and down. When the positioning rod 7 needs to be lubricated, the driving device 4 can be used to drive the slider 6 to slide up and squeeze the squeezing rod 12. The squeezing rod 12 is squeezed and slides up to squeeze the spring 11. The squeezing rod 12 slides up and drives the oil outlet 10 to slide up. The square groove at the side end of the oil outlet 10 allows the lubricating oil to flow to the positioning rod 7 for lubrication. Then the slider 6 slides down, the spring 11 squeezes the squeezing rod 12 to slide down and drives the oil outlet 10 to slide down. The square groove is closed by the oil storage box 5 and the lubricating oil is no longer The oil storage box 5 flows out, and then the slider 6 continues to slide down for squeezing. When the oil storage box 5 needs to be supplemented, the sliding handle 8 at one end can be pressed. The sliding handle 8 squeezes the card block 14 to slide up, and the card block 14 slides up to squeeze the spring 2 15. When the card block 14 completely slides out of the T-block 9, it can be slid horizontally to slide the T-block 9 and the oil storage box 5 out for replenishment, and then the T-block 9 drives the oil storage box 5 to slide back to its original position, and the sliding handle 8 is released. At this time, the spring 2 15 squeezes the card block 14 to slide in and be fixed inside the upper end of the T-block 9. At this time, the inclined block 13 is squeezed to slide to both ends and drives the sliding handle 8 to slide back to its original position.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
