Description

Technical Field

[0001] This utility model relates to the field of oil injection device technology, specifically an oil injection device with a filter sealing ring having a positioning structure. Background Technology

[0002] The sealing ring of a suction filter is a crucial component. It is primarily made of rubber or other materials with excellent sealing properties. Its purpose is to seal all connections within the suction filter, preventing fluid leakage into non-filtration channels. During suction filtration, a pressure difference exists inside the filter, and the sealing ring effectively withstands this pressure, ensuring the overall sealing of the filter structure. Whether in solution filtration in the chemical industry or in simple vacuum filtration operations in the laboratory, the suction filter sealing ring is indispensable; its performance directly affects the filter's efficiency, filtration accuracy, and service life.

[0003] When using a filter suction seal ring, an oil film needs to be formed by spraying oil to fill the gap between the seal ring and the sealing surface to enhance the sealing performance, reduce friction and wear to extend its service life, isolate air and moisture to prevent corrosion and delay aging, reduce energy loss, and stabilize the working state of the equipment. At present, during the oil spraying process, most devices simply place the seal ring on the surface of the oil spraying fixture without limiting its position, which causes shaking during the oil spraying process and reduces the oil spraying effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an oil spraying device with a filter sealing ring having a positioning structure, including a main body shell, a fixed side plate fixedly connected to the rear end of the main body shell, a protective shell fixedly connected to the right end of the fixed side plate, a servo motor installed inside the protective shell, a lead screw fixedly connected to the output end of the servo motor, a moving platform connected to the surface of the lead screw, a positioning frame fixedly connected to the top of the moving platform, a slider fixedly installed at the bottom of the positioning frame, a slide rail slidably connected to the surface of the slider, a top plate fixedly connected to the bottom of the slide rail, an oil spraying fixture installed on the top of the top plate, and a positioning plate provided inside the oil spraying fixture.

[0005] The above technical solution involves setting up a positioning frame, placing the workpiece on the positioning plate, and starting the servo motor. The output of the servo motor drives the positive and negative lead screws to rotate. The rotation of the positive and negative lead screws causes two moving tables to move in opposite directions on the surface of the lead screws, synchronously driving the positioning frame to move in the opposite direction until the surface of the positioning frame contacts the surface of the workpiece, thus positioning and fixing the workpiece inside the positioning plate. This prevents the workpiece from being unable to be positioned and fixed during the oil spraying process, which would otherwise result in a poor oil spraying effect.

[0006] As a further improvement to the above solution, there are two fixed side plates, which are symmetrically and evenly distributed around the center of the rear surface of the main body shell, and the end of the positive and negative lead screws near the protective shell passes through the fixed side plates.

[0007] As a further improvement to the above solution, two moving platforms are provided, which are symmetrically and evenly distributed around the center of the top of the lead screw, and the bottom of the top plate is fixedly installed on the top of the main body shell.

[0008] Through the above technical solution, the two moving platforms are symmetrically distributed, ensuring uniform force on the lead screw, reducing localized wear, and extending the lead screw's service life. The top plate is fixed to the top of the main body shell, ensuring its stability and providing reliable support for the oil spraying fixture, thus guaranteeing the oil spraying operation.

[0009] As a further improvement to the above solution, the bottom of the spraying fixture penetrates through the top plate, and the positioning plate is located at the center of the inside of the spraying fixture.

[0010] Through the above technical solution, the oil spraying fixture penetrates through the top plate, ensuring that the oil spraying fixture can accurately reach the oil spraying position and improve the oil spraying accuracy. The positioning plate is located in the center of the oil spraying fixture, which is conducive to the precise positioning of the sealing ring and ensures the uniformity of oil spraying.

[0011] As a further improvement to the above solution, an oil tank is installed on the front of the main body shell, an air source control console is fixedly connected to the front of the main body shell, a high-frequency pulse stage is fixedly connected to the front of the main body shell, a workpiece clamping stage is installed on the front of the main body shell, an oil-gas mixing box is fixedly connected to the front of the main body shell, and an oil pump is installed on the main body shell.

[0012] Through the above technical solution, the oil tank is installed on the front of the main body shell to provide an oil and gas source for oil spraying, which facilitates the oil spraying operation. The air source control console can control the air source and provide conditions for oil and gas propulsion, cleaning and other operations during the oil spraying process. The high-frequency pulse stage generates high-frequency pulses, which can be used for paint mixing, atomization and other functions to improve the quality and efficiency of oil spraying. The workpiece clamping stage can fix the workpiece and prevent it from moving during oil spraying, thus ensuring the accuracy of oil spraying. The paint mixing box can mix paint to meet different oil spraying needs. The oil pump can draw paint from the oil tank and deliver it to ensure that the oil spraying operation continues.

[0013] As a further improvement to the above solution, the gas source control console is located below the oil tank, the high-frequency pulse stage is located below the gas source control console, the oil-gas mixing box is located below the high-frequency pulse stage, and the oil pump is located to the right of the paint mixing box.

[0014] With the above technical solution, the air source control console is located below the oil tank, which facilitates the coordination of the two functions, such as the air source assisting in oil and gas extraction. The high-frequency pulse station is located below the air source control console, which is conducive to the coordination of the two functions, such as the air source providing power for pulse generation. The oil and gas mixing box is located below the high-frequency pulse station, which is convenient for receiving the processed paint or mixing the paint with the help of pulse energy. The oil pump is located on the right side of the paint mixing box, which is convenient for extracting the mixed paint for spraying operations.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a positioning frame to place the workpiece onto the positioning plate. A servo motor is then started, and its output drives the positive and negative lead screws to rotate. This rotation causes two moving platforms to move in opposite directions on the surfaces of the lead screws, simultaneously moving the positioning frame in the opposite direction until the surface of the positioning frame contacts the surface of the workpiece. This positions and fixes the workpiece inside the positioning plate, preventing the workpiece from being unable to be positioned and fixed during the oil spraying process, which would otherwise result in a poor oil spraying effect.

[0017] This invention uses a slider to limit the position of the positioning frame during its movement, ensuring stable movement and preventing the positioning frame from shifting. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

A fixed side plate 2 is fixedly connected to the rear end of the main body shell 1. A protective shell 3 is fixedly connected to the right end of the fixed side plate 2. A servo motor 4 is installed inside the protective shell 3. A positive and negative lead screw 5 is fixedly connected to the output end of the servo motor 4. A moving platform 6 is drivenly connected to the surface of the positive and negative lead screw 5. A positioning frame 61 is fixedly connected to the top of the moving platform 6. A slider 7 is fixedly installed at the bottom of the positioning frame 61. A slide rail 8 is slidably connected to the surface of the slider 7. A top plate 9 is fixedly connected to the bottom of the slide rail 8. An oil spraying fixture 10 is installed on the top of the top plate 9. A positioning plate 11 is provided inside the oil spraying fixture 10.

[0027] There are two fixed side plates 2. The two fixed side plates 2 are evenly distributed symmetrically around the center of the rear surface of the main body shell 1. The end of the protective shell 3 near the positive and negative screws 5 passes through the fixed side plate 2.

[0028] There are two moving platforms 6, which are symmetrically and evenly distributed around the top center of the positive and negative lead screws 5. The bottom of the top plate 9 is fixedly installed on the top of the main body shell 1.

[0029] The bottom of the spraying fixture 10 penetrates the top plate 9, and the positioning plate 11 is located at the center of the inside of the spraying fixture 10.

[0030] An oil tank 12 is installed on the front of the main body shell 1. An air source control console 13 is fixedly connected to the front of the main body shell 1. A high-frequency pulse stage 14 is fixedly connected to the front of the main body shell 1. A workpiece clamping stage 15 is installed on the front of the main body shell 1. An oil-gas mixing box 16 is fixedly connected to the front of the main body shell 1. An oil pump 17 is installed on the main body shell 1.

[0031] The gas source control console 13 is located below the oil tank 12, the high-frequency pulse stage 14 is located below the gas source control console 13, the oil-gas mixing box 16 is located below the high-frequency pulse stage 14, and the oil pump 17 is located to the right of the oil mixing box 16.

[0032] The implementation principle of the oil spraying device for a filter sealing ring with a positioning structure in this embodiment is as follows: When spraying oil onto the filter sealing ring, the workpiece is placed inside the positioning disk 11 for positioning. Then, the servo motor 4 is started. The output end of the servo motor 4 drives the positive and negative lead screws 5 to rotate. The rotation of the positive and negative lead screws 5 drives the two moving tables 6 to move in opposite directions on the surface of the positive and negative lead screws 5, and synchronously drives the positioning frame 61 to move in opposite directions until the surface of the positioning frame 61 contacts the surface of the workpiece, thereby positioning and fixing the workpiece inside the positioning disk 11. This avoids the workpiece from being unable to be positioned and fixed during the oil spraying process, which would result in a poor oil spraying effect.

[0033] The slider 7 limits the position of the positioning frame 61 during its movement, ensuring stable movement and preventing the positioning frame 61 from shifting.
