Detailed implementation manner
[0024] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] As Figures 6 to 10 shown, the present utility model provides an iron filings cleaning device for the oil passage hole of a phase shifter rotor, including a bottom plate 1. A product mounting seat 2 is connected to the top surface of the bottom plate 1. An axially penetrating stepped hole 21 that is larger at the top and smaller at the bottom is provided on the top surface of the product mounting seat 2. An iron filings blanking hole 101 is vertically penetrated through the bottom plate 1 at a position below the stepped hole 21. A positioning pin 22 is provided on the top surface of the stepped hole 21. The phase shifter rotor 3 is placed in the stepped hole 21 of the product mounting seat 2 and is limited against rotation and movement by inserting the positioning pin 22 into the positioning hole 31 at its bottom surface. An operation hole 23 is provided on the side surface of the product mounting seat 2. The number and position of the operation hole 23 correspond one by one to those of the oil passage hole 32 of the phase shifter rotor. A cylinder 4 is provided on the bottom plate 1 outside each operation hole 23. The front end of the piston rod of the cylinder 4 is connected with an ejector pin 5. The front end of the ejector pin 5 passes through the operation hole 23 and then inserts into the oil passage hole 32 of the phase shifter rotor. The outer diameter of the ejector pin 5 and the inner diameter of the oil passage hole 32 are dimensionally adapted, and the ejector pin 5 penetrates out of the oil passage hole 32 from the outside to the inside under the action of the cylinder 4 to clean the iron filings. A confluence exhaust source assembly 6 and a control valve 7 are provided on the bottom plate 1. The intake pipes and exhaust pipes of all the cylinders 4 are integrally controlled and switched through the confluence exhaust source assembly 6 and the control valve 7 respectively.
[0026] In the above solution, handle frames 8 are connected to the left and right sides of the top surface of the bottom plate 1.
[0027] In addition, cushion blocks 9 are connected to the left and right sides of the bottom surface of the bottom plate 1.
[0028] Furthermore, a collection box 10 for receiving iron filings is provided below the iron filings blanking hole 101 of the bottom plate 1.
[0029] Specifically, the cylinder 4 is connected to the connecting frame 11 by screws, and the connecting frame 11 is connected to the bottom plate 1 by bolts.
[0030] Specifically, the size of the iron filings blanking hole 101 is larger than the size of the lower small hole of the stepped hole 21 and smaller than the size of the upper large hole of the stepped hole 21.
[0031] Furthermore, the inner diameter of the operation hole 23 is larger than the inner diameter of the oil passage hole 32 of the phase shifter rotor.
[0032] The working principle of the utility model is as follows:
[0033] The phase shifter rotor 3 is placed in the stepped hole 21 of the product mounting seat 2, and anti-rotation and anti-movement limits are achieved by inserting the positioning pin 22 into the positioning hole 31 on its bottom surface. All cylinders 4 are controlled by the control valve 7 to push the ejector pins 5 forward. The ejector pins 5 pass through the operation hole 23 and the oil passage hole 32 to eject the iron filings remaining in the oil passage hole 32. Since the outer diameter of the ejector pin 5 and the inner diameter of the oil passage hole 32 are matched, it is ensured that no iron filings remain. The ejected iron filings fall into the collection box 10 below after passing through the stepped hole 21 and the iron filing dropping hole 101, realizing the complete ejection of the iron filings. Then, the control valve 7 is used to control the cylinder rod to retract, the ejector pin 5 retracts and leaves the oil passage hole 32, and the phase shifter rotor 3 is taken out upward. The next phase shifter rotor to be cleaned is replaced, and the above operations are repeated.
[0034] The above is only the preferred embodiment of the utility model, and does not impose any formal restrictions on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
