Description

Technical Field

[0001] This application belongs to the technical field of pumps, and particularly relates to a lubricating oil pump. Background Art

[0002] The lubricating oil pump is mainly used to transport lubricating oil in the lubrication systems of various mechanical equipment. The AC lubricating oil pump is vertically installed on the top plate of the main oil tank, sucks oil through the filter screen at the bottom of the oil pump, and discharges the oil to the inlet pipe of the main oil pump and to the bearing lubricating oil header pipe through the oil cooler. This pump is controlled by a pressure switch and a three-position switch installed in the control room, and a flap check valve is installed at the outlet to prevent the oil from flowing back from the system.

[0003] Regarding the piston rod assembly of the lubricating oil pump, there is no fixed tooling fixture. One can only hold a wrench with the left hand to clamp it, and at the same time hold another wrench with the right hand to lock it. Without a tooling fixture for fixing parts, it is very easy for the wrench to slip off inadvertently, and sometimes it may cause work injuries to employees. Therefore, it is extremely urgent to design a fixed tooling fixture.

[0004] For this reason, we propose a lubricating oil pump to solve the above problems. Utility Model Content

The outer surface of the connector is fixedly connected with a steering block. The inner wall of the steering block is rotatably connected with a pressing frame. A threaded rod is arranged inside the pressing frame. The top end of the threaded rod penetrates through two gaskets and extends above the pressing frame. One side surfaces of the two gaskets close to each other are in contact with the upper surface and the bottom surface of the pressing frame. A threaded cap is fixedly connected to the outer surface of the threaded rod. The upper surface of one of the gaskets is in contact with the bottom surface of the threaded cap. A spring is fixedly connected to the bottom surface of the other gasket. The end of the spring away from the gasket is fixedly connected with a conical block.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] A raising block 6 is fixedly connected to the upper surface of the base 1, a rotating seat 7 is fixedly connected to the upper surface of the raising block 6, a connector 9 is rotatably connected to the inner wall of the rotating seat 7, a limiting component 18 is arranged inside the conversion pipe 17, the outer surface of the limiting component 18 is threadedly connected to the inner wall of the conversion pipe 17, the limiting component 18 plays a role in restricting the piston, and in addition, the threaded connection relationship between the limiting component 18 and the conversion pipe 17 plays a role in facilitating disassembly and assembly.

[0026] A steering block 8 is fixedly connected to the outer surface of the connector 9, a pressing frame 10 is rotatably connected to the inner wall of the steering block 8, a threaded rod 11 is arranged inside the pressing frame 10, a piston rod 19 is slidably connected to the inner wall of the limiting component 18, one end of the piston rod 19 close to the limiting component 18 sequentially passes through the pump body 16 and the conversion pipe 17 and extends to the outside of the pump body 16. The piston rod 19 plays a role in supporting and linking the pistons at both ends to ensure that the moving stroke between the pistons at both ends is consistent.

[0027] The top end of the threaded rod 11 penetrates through two gaskets 12 and extends above the pressing frame 10. One side surface of the two gaskets 12 that are close to each other is in contact with the upper surface and the bottom surface of the pressing frame 10. An expansion rod 21 is arranged on the outer side of the pump body 16. The outer surface of the expansion rod 21 is slidably connected to the inner wall of the conversion pipe 17. The expansion rod 21 is a protective cover of the piston assembly and plays a role in protecting the piston assembly.

[0028] A threaded cap 13 is fixedly connected to the outer surface of the threaded rod 11. The upper surface of one of the gaskets 12 is in contact with the bottom surface of the threaded cap 13. A sealing cover 22 is arranged on the outer side of the expansion rod 21. The back surface of the sealing cover 22 is fixedly connected to the front surface of the expansion rod 21. The sealing cover 22 is used to fixedly seal the expansion rod 21. Using the sealing cover 22 can facilitate daily maintenance and is convenient for applying lubricating oil.

[0029] The bottom surface of the other gasket 12 is fixedly connected to a spring 15. One end of the spring 15 away from the gasket 12 is fixedly connected to a conical block 14. Two piston heads 20 are fixedly connected to the outer surface of the piston rod 19. The outer surface of one of the piston heads 20 is slidably connected to the inner wall of the expansion rod 21. The two piston heads 20 play a role in sealing and are used to slide inside the expansion rod 21 and the pump body 16.

[0030] The working principle of the present utility model is as follows: When in use, first fix the base 1 on the workbench through bolts, and then place the pump body 16 on the mounting seat 2. At this time, the tail end of the pump body 16 just gets stuck at the position between the positioning plate 4 and the limiting block 5, playing a role in positioning the overall position of the pump body 16 on the mounting seat 2. Then use the limiting seat 3 to clamp the left and right sides of the pump body 16. At this time, use the heightening block 6 to increase the height of the rotating seat 7. The rotating seat 7 is rotationally connected to the steering block 8 through the connector 9. Using the rotational connection relationship between the steering block 8 and the pressing frame 10, the action of lifting or lowering the pressing frame 10 can be realized. Then, due to the fixed connection relationship between the threaded rod 11 and the conical block 14, when the threaded cap 13 is rotated, the length of the threaded rod 11 can be contracted, and then the spring 15 is compressed under the influence of the gasket 12. Using the fixed connection relationship between the spring 15 and the conical block 14, at this time, the conical block 14 can press down on the inner wall of the pump body 16. Thus, the adjustment of the threaded cap 13 is the adjustment of the pressure on the conical block 14, and then the pump body 16 can be effectively pressed down from above. Through the cooperation of the multi-directional fixing components, the pump body 16 can be firmly fixed on the mounting seat 2, solving the problem that it is easy to cause accidental injury when using two wrenches for installation in the traditional way.
