Description
Technical Field
The utility model relates to an oil blanket device's field especially relates to a device for pressure equipment oil blanket.
Background
Nowadays, oil seals are applied more and more widely in various mechanical equipment, and the oil seals have the advantages of low cost, good sealing performance, simple structure and the like. The quality of an oil seal directly determines the quality of an oil seal device, the oil seal with good sealing performance can be used in a machine for a long time, the quality of the oil seal is not problematic most of the time, but the oil seal is possibly damaged due to improper operation or incomplete press-fitting devices in the press-fitting process, so that the oil seal device is not willing to be seen, and therefore the device which can be used for conveniently press-fitting the oil seal is urgently needed.
At present, two methods are mostly adopted for installing the oil seal:
1. artifical manual installation oil blanket, artifical installation oil blanket are applicable to the oil blanket of small in quantity, have with low costs, convenient characteristics, but owing to need artifically adjust oil blanket and oil seal seat well in the installation to still damage the oil blanket lip easily and pressing the jumping out of in-process oil blanket spring.
2. The special press-fitting oil seal is characterized in that a pressure head and a press-fitting base of the oil seal which is pressed by the special press are customized, the special press-fitting oil seal is only suitable for fixed oil seals and oil seal seats, and the special press-fitting oil seal is suitable for large-batch oil seal press-fitting, but has high cost and large investment, and can not be installed for oil seals without special pressure heads and press-fitting bases.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem of current oil blanket pressure equipment, the utility model aims at providing a device for pressure equipment oil blanket, this device simple structure, convenient to use, adjustment are nimble, extensive applicability, consequently can be used to the pressure equipment that is used for of oil blanket, have improved the sealing performance of device, have reduced the leakage.
In order to achieve the purpose, the utility model adopts the following scheme: the utility model provides a device for pressure equipment oil blanket, mainly by the pressure head, the sleeve, the positioning core axle, the locating piece, the pressure equipment base, the oil seal ring is constituteed, the positioning core axle is installed on the pressure equipment base, the locating piece passes through the bolt and is connected in the recess in the pressure equipment base with the nut, the locating piece can slide wantonly on the pressure equipment base, the last length scale that has of pressure equipment base, conveniently adjust the position of locating piece, so that fix a position the oil seal seat of equidimension not, the oil seal ring cover is on the positioning core axle, the sleeve is connected with the pressure head with bolt, do the up-and-down motion on the positioning core axle together, when moving screw thread department, need rotate the pressure head and drive.
The sleeve, the positioning core shaft, the oil seal ring, the oil seal and the oil seal seat are coaxially arranged.
When the positioning blocks slide on the press-fitting base, the same distance of 4 positioning blocks is ensured.
The maximum diameter of the thread above the positioning mandrel must not exceed its diameter.
The sleeve is free to slide when moving over the locating mandrel without reaching the threads.
The utility model has the advantages that: the most convenient method is adopted for press mounting the oil seal, the lip of the oil seal is protected, the positioning blocks on the press mounting base can be adjusted to position the oil seal seats with different sizes, the applicability is wide, when the oil seal needs to be slowly press mounted, the oil seal can be realized by rotating the pressure head, and the problem that the collision speed of the oil seal and the oil seal seat is too high due to too large force during press mounting can be solved.
