[0019] As Figures 1-4 shown, a through hole fine milling device for oil pump end cover processing, including device table 1, milling machine table 2, frame 3, cylinder 4, hanging table 5, motor 6 and through hole milling cutter 7, the milling machine table 2 is arranged on the device table 1, the frame 3 is welded on the device table 1, the cylinder 4 is fixed below the top of the frame 3, the hanging table 5 is fixed on the extension end of the cylinder 4, the motor 6 is fixed on the bottom of the hanging table 5, the through hole milling cutter 7 is installed on the output shaft of the motor 6, the milling cutter automatic cleaning mechanism is further arranged on the frame 3, the milling cutter automatic cleaning mechanism includes electric push rod 8, shielding frame 9, collection box 10, steel wire brush 11, crossbeam 12 and photoelectric switch 13, the electric push rod 8 and the crossbeam 12 are fixed on the inner wall of the frame 3, the shielding frame 9 is fixed on the extension end of the electric push rod 8, the collection box 10 is fixed on the bottom of the shielding frame 9, and a plurality of steel wire brushes 11 are further arranged in the shielding frame 9, and the photoelectric switch 13 is fixed below the inner end of the crossbeam 12, the iron filings on the through hole milling cutter are automatically cleaned by using mechanization instead of manual work, the cleaning speed is fast, time and labor are saved, and the efficiency is convenient, thereby solving the defects of the existing through hole fine milling device and improving the practicability.

[0020] In the embodiment, two sleeve rods are arranged on the inner walls of the two sides of the shielding frame 9, and the steel wire brush 11 is sleeved on the sleeve rod, which is used for fixing the steel wire brush 11 and also facilitates dismounting and replacing.

[0021] In the embodiment, the shielding frame 9 directly faces the through hole milling cutter 7, so that the steel wire brush 11 can accurately stick to the through hole milling cutter 7 to wipe off the iron filings.

[0022] In the embodiment, the photoelectric switch 13 is located directly above one side of the hanging table 5, and the hanging table 5 is used as a shielding object to ensure that the photoelectric switch 13 can open and close the electric push rod 8 according to the position of the through hole milling cutter 7.

[0023] In the embodiment, the relay 14 is further arranged on the crossbeam 12, and the photoelectric switch 13 is electrically connected with the relay 14 and the electric push rod 8 to form an automatic control circuit and realize automatic cleaning.

[0024] The photoelectric switch used in the application is an existing product, for example: a diffuse reflection photoelectric switch of a forest bird brand, E3F-DS10C4 model, a working voltage of 6-36V, a detection distance of 5-25cm adjustable, and a relay as a matching equipment, both of which are existing mature technologies, and the specific internal structure and principle thereof belong to the technical scope that can be understood by those skilled in the art, and will not be described here.

[0025] The principle and advantages of this utility model: The photoelectric switch 13 is connected to a power source. The detection distance of the photoelectric switch 13 is set. For example, when the platform 5 is raised to its highest point, the distance between the photoelectric switch 13 and the platform 5 is 15cm, so the sensing distance of the photoelectric switch is set to 16cm. Then, the photoelectric switch 13 is set to the normally open state. When there is no obstruction within the detection distance of the photoelectric switch 13, the circuit it controls is open, that is, the electric push rod 8 is not energized. When there is an obstruction within the detection distance of the photoelectric switch 13, the circuit it controls is closed, that is, the electric push rod 8 is energized. Then, if... Figure 2 As shown, place the end cap on the milling machine worktable 2, turn on the cylinder 4 and motor 6. The motor 6 slowly rotates the through-hole cutter 7, and the cylinder 4 lowers the through-hole cutter 7, pressing it against the oil pump end cap to create a through hole. After completing the through hole, as shown... Figure 3 As shown, the cylinder 4 retracts, the platform 5 rises, and the distance between the platform 5 and the photoelectric switch 13 is less than 16cm. At this time, the photoelectric switch 13 closes the circuit of the electric push rod 8, the electric push rod 8 extends, and pushes the shielding frame 9 towards the through-hole milling cutter 7. After the through-hole milling cutter 7 contacts the wire brush 11, as the through-hole milling cutter 7 slowly rotates, the wire brush 11 can wipe off the iron filings adhering to its surface. The iron filings fall into the collection box 10 and are collected. After cleaning is completed, as shown... Figure 1 As shown, cylinder 4 is turned on and motor 6 is turned off. Cylinder 4 is turned on again and slowly extended by 2-5cm, so that the distance between the platform 5 and photoelectric switch 13 is greater than 15cm. At this time, the circuit controlled by photoelectric switch 13 is disconnected, that is, the electric push rod 8 is not energized and automatically retracts, thereby pulling back the shielding frame 9. The through-hole milling device with this structural design for pump end cover processing uses mechanization to automatically clean the iron filings on the through-hole milling cutter instead of manual labor. The cleaning speed is fast, saving time and effort, and is efficient and convenient, thereby solving the defects of the existing through-hole milling device and improving its practicality.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
