[0003] The vacuum circulation oiling machine uses a vacuum pump as a power source to work. During the operation, the vacuum pump will generate a certain amplitude of vibration. Since the vacuum circulation oiling machine is installed through an external frame, a certain amount of noise will be generated during operation. In order to buffer the vibration source and reduce the source of the noise source, a vacuum circulation oiling machine is proposed to solve the above problems. Utility Model Content
[0004] In response to the deficiencies in the prior art, the present application provides a vacuum cycle oiling machine that has the advantages of buffering the noise source generated by the vibration of a true vacuum pump.

[0007] The buffer rod includes a vertical cylinder fixedly mounted on the mounting frame, an oil cylinder fixedly mounted on the outside of the mounting frame, an extension seat fixedly mounted on the outside of the oil cylinder, the extension seat extends into the mounting frame and is recessed with a groove for the vertical cylinder to be inserted, the vertical cylinder is inserted into the extension seat, an oil passage connecting the two ends is opened through the extension seat, and a pressure plate is slidably installed in the oil cylinder.
[0008] Furthermore, a positioning plate is fixedly mounted on the mounting frame.
[0009] Furthermore, a piston rod extending through and to the outside of the vertical cylinder is slidably installed inside the vertical cylinder, and a connecting disk is fixedly installed on one end of the piston rod extending to the outside of the vertical cylinder, and the connecting disk is fixedly connected to the bottom of the movable plate.
[0010] Furthermore, a plunger head is fixedly mounted on one end of the piston rod that passes through the interior of the vertical cylinder, and a side surface of the plunger head is tightly fitted to the inner wall of the vertical cylinder.

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0021] See also Figure 1-3 In this embodiment, a vacuum circulation oiling machine includes a mounting frame 1 for support and a vacuum pump 3 located on the mounting frame 1. An oiling machine assembly for circulating oil supply is provided on the mounting frame 1. The vacuum pump 3 and the oiling machine assembly are connected by a pipeline, so that the vacuum pump 3 can maintain a connected state while moving relative to the mounting frame 1.
[0022] In this embodiment, a movable plate 2 is fixedly mounted on the lower end of the vacuum pump 3 , and the movable plate 2 is slidably connected to the mounting frame 1 , so that the movable stability of the vacuum pump 3 relative to the mounting frame 1 is improved.
[0023] It should be noted that a positioning plate 4 is also fixedly mounted on the mounting frame 1 , and the positioning plate 4 is used to limit the height position of the vacuum pump 3 so that the range of movement of the vacuum pump 3 can be limited.
[0024] In order to buffer the sliding of the movable plate 2, a buffer rod for buffering the movable plate 2 is provided between the movable plate 2 and the mounting frame 1 in this embodiment. The buffer rod includes a vertical cylinder 7 fixedly mounted on the mounting frame 1, a cylinder 5 fixedly mounted on the outside of the mounting frame 1, an extension seat 6 fixedly mounted on the outside of the cylinder 5, the extension seat 6 extends into the mounting frame 1 and is recessed with a groove for the vertical cylinder 7 to be inserted, and the vertical cylinder 7 is inserted into the extension seat 6;
[0025] Furthermore, an oil passage 12 communicating with both ends is formed through the extension seat 6 , one end of the oil passage 12 is communicated with the vertical cylinder 7 , and the oil passage 12 and the vertical cylinder 7 are filled with hydraulic oil.
[0026] In a specific implementation, the hydraulic oil in the vertical cylinder 7 is squeezed so that the hydraulic oil can be injected into the oil cylinder 5 .
[0027] In this embodiment, a pressure plate 15 is slidably installed in the oil cylinder 5. Under the pressure of hydraulic oil, the pressure plate 15 can squeeze the air in the oil cylinder 5 to complete the buffering.
[0028] It should be noted that a piston rod 8 is slidably installed inside the vertical cylinder 7 and extends to the outside of the vertical cylinder 7. A connecting disk 9 is fixedly installed on one end of the piston rod 8 extending to the outside of the vertical cylinder 7. The connecting disk 9 is fixedly connected to the bottom of the movable plate 2.
[0029] Through the relatively fixed connection between the connecting plate 9 and the movable plate 2 , the movable plate 2 can flexibly transmit the force to the piston rod 8 and pull the piston rod 8 to move up and down relative to the vertical cylinder 7 .
[0030] In order to seal one end of the piston rod 8 , a plunger head 13 is fixedly mounted on one end of the piston rod 8 that passes through the interior of the vertical cylinder 7 . The side surface of the plunger head 13 is tightly fitted to the inner wall of the vertical cylinder 7 .
[0031] It should be noted that a sealing ring is also provided on the outside of the plunger head 13 to further improve the installation tightness of the plunger head 13.
[0032] In this embodiment, a closing plate 14 is fixedly mounted on the outside of the piston rod 8 and abuts against the upper end of the vertical cylinder 7 . The closing plate 14 is used to block the upper end of the vertical cylinder 7 to enhance the sealing effect of the vertical cylinder 7 .
[0033] It should be noted that a fixing plate 10 is fixedly installed on the outside of the vertical cylinder 7, and a push spring 11 is installed between the fixing plate 10 and the connecting disk 9 for pushing the connecting disk 9 to reset. One end of the push spring 11 is fixedly connected to the fixing plate 10, and the other end is fixedly connected to the connecting disk 9.
[0034] In a specific implementation, the push spring 11 pushes the connecting disk 9 to move relative to the fixing plate 10, so that the connecting disk 9 can move relative to the vertical cylinder 7 and complete the reset.
[0035] In this embodiment, the lower end of the vertical cylinder 7 is further connected to a pressure relief port 16 for pressure relief, and the pressure relief port 16 is sealed with a sealing plug for sealing the pressure relief port 16 .
[0036] The working principle of the above embodiment is:
[0037] By driving the vacuum pump 3, the vacuum pump 3 generates vibration during operation. At this time, the movable plate 2 connected to the bottom of the vacuum pump 3 pulls the connecting plate 9 to move relative to the vertical cylinder 7. The connecting plate 9 pushes the piston rod 8 to slide and extend relative to the vertical cylinder 7. The plunger head 13 connected to the lower end of the piston rod 8 pushes the hydraulic oil located at the lower end of the vertical cylinder 7 and the oil channel 12 toward the oil cylinder 5. The hydraulic oil squeezes the air in the cavity of the oil cylinder 5 by squeezing the pressure plate 15 located in the oil cylinder 5, thereby absorbing kinetic energy and delaying the vibration of the movable plate 2.
