DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Embodiment 1:

[0037] An automatic oiling device for a press machine, in order to facilitate automatic oiling, such as Figure 1-6 As shown, it includes a fuel tank 1 and a filling part, and the filling part includes:

[0038] Bracket 2: It is fixed to the outer wall of one side of the oil tank 1 by bolts, and a servo motor 3 is fixed to the outer wall of one side of the bracket 2 by bolts;

[0039] Bevel gear 1 9: It is fixed to the output end of the servo motor 3 by a pin;

[0040] Bottom tube 23: It is welded to the outer wall of the bottom of the oil tank 1, and a rotating seat 24 is welded to the bottom of the bottom tube 23, and a through hole 1 is opened at the bottom of the rotating seat 24;

[0041] L-shaped plate 22: It is fixed to the outer wall of the bottom of the oil tank 1 by bolts, and a lining plate 29 is welded to the outer wall of one side of the L-shaped plate 22;

[0042] Hollow tube 11: It is rotatably connected to the inner wall of the through hole opened on the surface of the lining plate 29, and an embedded tube 25 is welded on the top of the hollow tube 11, and the rotating seat 24 is rotatably connected to the inner wall of the circumference of the embedded tube 25;

[0043] The adjusting plate 26 is welded to the inner wall of the embedded tube 25, and a through hole 2 having the same inner diameter as the through hole 1 is opened on the surface of the adjusting plate 26;

[0044] The bellows 6 is sleeved on the bottom of the hollow tube 11 , and a lead-out head 27 is integrally formed at the bottom of the bellows 6 .

[0045] The transmission is carried out between the circumferential outer wall of the hollow tube 11 and the bevel gear 9 via a clutch assembly.

[0046] The servo motor 3 can drive the bevel gear 9 to rotate. After the clutch transmission component is used to make it contact with the bevel gear 9, the servo motor 3 drives the hollow tube 11 and the adjustment plate 26 to rotate through the clutch transmission component. When the through hole 2 opened on the surface of the adjustment plate 26 and the through hole 1 opened at the bottom of the rotating seat 24 overlap with each other, the lubricating oil in the oil tank 1 is introduced into the bellows 6 through the through holes 1 and 2, and finally discharged through the outlet head 27. The discharged lubricating oil can be used to refuel the press. The bellows 6 can move in any direction, so that the outlet head 27 moves in any direction, thereby improving the flexibility of refueling.

[0047] When refueling is completed, the clutch assembly is used to make the servo motor 3 drive the hollow tube 11 and the adjustment plate 26 to rotate again. When the through hole 2 on the surface of the adjustment plate 26 and the through hole 1 at the bottom of the rotating seat 24 are misaligned with each other, the lubricating oil in the oil tank 1 is no longer discharged, thereby realizing the interception of the lubricating oil.

[0048] Furthermore, the clutch assembly includes a bevel gear 19 and an extension plate 20, the extension plate 20 is welded to the outer wall of one side of the oil tank 1, and the surface of the extension plate 20 is rotatably connected with the bevel gear 19 meshing with the bevel gear 19, and the bottom of the bevel gear 19 is welded with an adsorption seat 18, the surface of the L-shaped plate 22 is rotatably connected with the air pressure cylinder 4, and the top of the air pressure cylinder 4 is slidably connected with the piston rod 12, and the bottom of the piston rod 12 is welded with a piston plate 13, and the outer wall of the bottom of the piston plate 13 and the bottom of the air pressure cylinder 4 are connected. A same spring 30 is fixed between the inner walls of the parts by a clamping method, a support plate 17 is welded on the top of the piston rod 12, and a conical block 21 adapted to the adsorption seat 18 is welded on the top of the support plate 17, and an electromagnet 16 is fixed to the outer wall of the top of the support plate 17 by screws; the clutch assembly also includes a belt 10 and a pulley 31, the two pulleys 31 are respectively fixed to the bottom of the air pressure cylinder 4 and the circumferential outer wall of the hollow tube 11 by pins, and the belt 10 is used to transmit power between the two pulleys 31.

[0049] When it is necessary to use the servo motor 3 to drive the hollow tube 11 and the adjustment plate 26 to rotate, the electromagnet 16 is energized. The magnetic force generated by the electromagnet 16 after being energized can overcome the elastic force of the spring 30, and finally adsorbed on the outer wall of the bottom of the adsorption card seat 18. During this process, the conical block 21 is inserted into the inner wall of the card groove opened inside the adsorption card seat 18, so that the conical block 21 and the adsorption card seat 18 are engaged. During the rotation of the output end of the servo motor 3, the bevel gear 19 is driven to rotate by the bevel gear 19, so that the adsorption card seat 18 drives the conical block 21 to rotate. During the rotation, the conical block 21 synchronously drives the piston rod 12 and the air cylinder 4 to rotate, and the transmission action of the belt 10 and the pulley 31 is used to make the hollow tube 11 and the adjustment plate 26 rotate along the bottom of the rotating seat 24, so as to realize the extraction of lubricating oil.

[0050] Furthermore, the output end of the servo motor 3 is connected to a stirring column 8 via a coupling, and a stirring blade 7 is welded to the circumferential outer wall of the stirring column 8 .

[0051] After the lubricating oil is filled into the oil tank 1, when the electromagnet 16 is powered off, the rebound force of the spring 30 is used to disconnect the bevel gear 2 19 and the adsorption seat 18. When the servo motor 3 drives the stirring blade 7 and the stirring column 8 to rotate, the stirring blade 7 stirs the lubricating oil in the oil tank 1. The stirring can fully mix the different components in the lubricating oil.

[0052] Furthermore, the outer wall of the bottom of the L-shaped plate 22 is fixed with the shell 14 by embedding, and the same coil spring 15 is fixed between the inner wall of the shell 14 and the outer wall of the circumference of the air pressure cylinder 4 by clamping.

[0053] When the conical block 21 and the adsorption seat 18 are separated and the lubricating oil needs to be intercepted, the rebound force of the coil spring 15 is used to reset the hollow tube 11 and the electromagnet 16, so that the through hole 2 on the adjustment plate 26 and the through hole 1 at the bottom of the rotating seat 24 are misaligned, thereby completing the interception of the lubricating oil.

[0054] Working principle: When refueling is needed, first inject the lubricating oil into the oil tank 1 through the filling port on the top of the oil tank 1, and then energize the electromagnet 16. After energization, the electromagnet 16 generates magnetic force to overcome the elastic force of the spring 30, so that the electromagnet 16 is adsorbed on the outer wall of the adsorption seat 18. During this process, the conical block 21 is gradually inserted into the adsorption seat 18. At this time, the servo motor 3 can drive the adjustment plate 26 to rotate along the bottom of the rotating seat 24. When the through hole 2 opened on the surface of the adjustment plate 26 coincides with the through hole 1 opened at the bottom of the rotating seat 24, the lubricating oil in the oil tank 1 is discharged through the bellows 6 and the outlet head 27, so as to refuel the press. Embodiment 2:

[0055] An automatic oiling device for a press, such as Figure 1-6 As shown, in order to prevent dust from entering the bellows 6, this embodiment makes the following supplements on the basis of embodiment 1: the circumferential outer wall of the air cylinder 4 is connected to the air pressure tube 5 through a joint, and the end of the air pressure tube 5 away from the air cylinder 4 is bonded with a cylindrical air bag 28.

[0056] When the bevel gear 2 19 and the adsorption seat 18 are disconnected, the piston plate 13 moves down along the air pressure cylinder 4, and the volume of the chamber between the piston plate 13 and the bottom of the air pressure cylinder 4 decreases. The air in the chamber is introduced into the cylindrical airbag 28 through the air pressure tube 5. After expansion, the cylindrical airbag 28 blocks the outlet head 27, thereby effectively isolating external impurities and dust, and preventing dust from entering the bellows 6 through the outlet head 27.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
