Description

Technical Field

[0001] This utility model belongs to the technical field of oil injection equipment, and more specifically, it relates to an oil injection device for a gear pump. Background Technology

[0002] Gear pumps are rotary pumps that rely on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport or pressurize liquids. When a gear pump is working, there is relative movement between the gears and other components, such as the gears and the pump body. Oil injection can form a lubricating film on the metal surface, avoiding direct contact, thereby greatly reducing friction, reducing wear, and extending the service life of the gear pump.

[0003] When lubricating a gear pump, the operator must first hold the lubricating device to inject lubricating oil into the designated lubrication point on the pump. Then, the operator needs to lower the device and use a brush to spread the lubricating oil evenly. This process is not very convenient. Therefore, in view of this, this paper studies and improves the existing structure and its shortcomings to provide a gear pump lubrication device with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an oil injection device for gear pump machining, which is achieved by the following specific technical means:

[0005] An oil injection device for gear pump processing includes an oil reservoir, a piston slidably connected to the inner side of the oil reservoir, a rotary shaft seal fixedly embedded in the bottom side of the oil reservoir, an oil outlet pipe fixedly installed inside the rotary shaft seal, a rotary seat rotatably connected to the bottom side of the oil reservoir, a through hole provided on the top side of the rotary seat, a cavity provided inside the rotary seat, the inner side of the through hole being fixedly connected to the outer side of the oil outlet pipe, multiple sets of oil outlets provided on the bottom side of the rotary seat, and multiple sets of oil brushes fixedly installed on the bottom side of the rotary seat.

[0006] Furthermore, two sets of drive plates are symmetrically slidably connected to the outer side of the oil storage tank, and two sets of drive grooves are symmetrically provided on the outer side of the rotating seat. A connecting rod is fixedly installed on one side of each of the two sets of drive plates, and the two sets of connecting rods are slidably connected to the two sets of drive grooves respectively.

[0007] Furthermore, a drive rod is fixedly mounted on the top side of the piston, and a button is fixedly mounted on the top side of the drive rod.

[0008] Furthermore, the top of both sets of drive boards are fixedly connected to the bottom side of the button.

[0009] Furthermore, an outer shell is fixedly installed on the outside of the oil reservoir, and a sliding groove is provided on the outer shell corresponding to the drive plate. Both the outer shell and the oil reservoir are made of transparent PP material.

[0010] Furthermore, an oil inlet pipe is fixedly connected to both the outer shell and the oil reservoir. One end of the oil inlet pipe is located on the outside of the outer shell, and the other end is located on the inside of the oil reservoir. A one-way valve is fixedly installed on the inside of the oil inlet pipe.

[0011] Furthermore, scale lines are provided on the outer side of the outer casing.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the cooperation of a button and a drive rod, enables the piston to move flexibly and injects lubricating oil into the rotating seat through the oil outlet pipe. The button, drive plate, and connecting rod work together to rotate the rotating seat simultaneously with oil dispensing. The rotating seat, oil outlet, and oil brush work together to automatically spread lubricating oil onto the gear pump while simultaneously injecting it. Afterwards, the operator can manually apply any unevenly applied lubricating oil using the oil brush, achieving uniform application. This eliminates the tedious operation of separately using an oiling device and a brush to apply lubricating oil, increasing the convenience of product use. Attached Figure Description

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides an oil injection device for gear pump processing, including an oil reservoir 1, a piston 4 slidably connected to the inner side of the oil reservoir 1, a rotary shaft seal 2 fixedly embedded on the bottom side of the oil reservoir 1, an oil outlet pipe 3 fixedly installed on the inner side of the rotary shaft seal 2, a rotary seat 5 rotatably connected to the bottom side of the oil reservoir 1, a through hole provided on the top side of the rotary seat 5, a cavity provided on the inner side of the rotary seat 5, the inner side of the through hole being fixedly connected to the outer side of the oil outlet pipe 3, multiple sets of oil outlets 6 provided on the bottom side of the rotary seat 5, and multiple sets of oil brushes 7 fixedly installed on the bottom side of the rotary seat 5.

[0027] Two sets of drive plates 8 are symmetrically slidably connected to the outer side of the oil storage tank 1, and two sets of drive grooves are symmetrically provided on the outer side of the rotating seat 5. A connecting rod 9 is fixedly installed on one side of each of the two sets of drive plates 8. The two sets of connecting rods 9 are slidably connected to the two sets of drive grooves respectively, which can drive the rotating seat 5 to rotate flexibly.

[0028] A drive rod 10 is fixedly installed on the top side of the piston 4, and a button 11 is fixedly installed on the top side of the drive rod 10, which can drive the piston 4 to move flexibly and dispense oil.

[0029] The tops of both sets of drive plates 8 are fixedly connected to the bottom side of the button 11, which can drive the rotating seat 5 to rotate while the button 11 is pressed to release oil.

[0030] The outer shell 12 is fixedly installed on the outside of the oil reservoir 1. The outer shell 12 is provided with a sliding groove corresponding to the drive plate 8. Both the outer shell 12 and the oil reservoir 1 are made of transparent PP material, which makes it easy for the operator to observe how much lubricating oil is left in the oil reservoir 1.

[0031] The outer shell 12 and the oil reservoir 1 are both fixedly connected to an oil inlet pipe 13. One end of the oil inlet pipe 13 is located outside the outer shell 12, and the other end of the oil inlet pipe 13 is located inside the oil reservoir 1. A one-way valve is fixedly installed inside the oil inlet pipe 13, which can conveniently inject lubricating oil into the oil reservoir 1.

[0032] The outer shell 12 is provided with scale lines on its outer side to facilitate operators in controlling the amount of oil injected.

[0033] The working principle of this embodiment is as follows: When the gear pump needs to be filled with oil, first align the oil outlet 6 with the position to be filled on the gear pump, and make the oil brush 7 contact the position to be filled on the gear pump. Press the button 11 to drive the drive rod 10 to move. The drive rod 10 drives the piston 4 to move. The piston 4 squeezes the lubricating oil in the oil reservoir 1, so that the lubricating oil enters the cavity through the oil outlet pipe 3, and is injected into the position to be filled on the gear pump through multiple sets of oil outlets 6. At the same time, the button 11 drives the drive plate 8 to move. The drive plate 8 drives the rotating seat 5 to rotate through the connecting rod 9 and the drive groove. The rotating seat 5 drives the oil brush 7 to rotate and automatically apply the lubricating oil. The operator moves the oil brush 7 to manually apply the lubricating oil to the areas where it is not evenly applied, and completes the even application of the lubricating oil, thus completing the oil filling operation of the gear pump.
