At present, the pressure equipment distance that interior oil blanket up end corresponds the terminal surface to the seal receptacle leans on, the die control down, need change the mould adjustment when the deviation appears in the pressure equipment distance, there is certain error because of the oil blanket product height of many oil blanket suppliers, and the oil blanket of the same model that a producer used a plurality of moulds to produce also has the difference in height, so, when the oil blanket height changes, the pressure equipment of seal receptacle and oil blanket often needs dozens of moulds to change processing, wastes time and energy.
Disclosure of Invention
The utility model aims at providing a railway bearing seal receptacle oil blanket pressure equipment degree of depth stop device, through setting up this device between upper and lower moulding-die, can adjust the pressure equipment distance of upper and lower moulding-die spacing to the realization uses one set of mould to carry out the pressure equipment to the seal receptacle and the oil blanket of same model.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a railway bearing seal holder oil seal press-fitting depth limiting device comprises a fixing ring, limiting rods and a base, wherein the fixing ring is installed on an upper pressing die pressing ring through bolts, the fixing ring is integrally annular, positioning blocks are uniformly distributed on the outer cylindrical surface of the fixing ring, the limiting rods are arranged below the positioning blocks, the upper end of each limiting rod is in contact with the lower end surface of the corresponding positioning block, the base in threaded connection is arranged at the lower part of each limiting rod, the base is arranged on an installation seat of a lower pressing die, and the press-fitting distance between the upper pressing die and the lower pressing die is adjusted and limited through the lifting of the limiting rods on the base; the middle part of the lower end face of the base is provided with an axial hole, the middle part of the upper end face of the base is provided with a threaded hole communicated with the axial hole, and the threaded hole is in threaded connection with the lower end of the limiting rod.
The limiting rod is composed of a screw and a limiting block which are fixed into a whole, the limiting block is arranged at the upper end of the screw, and the upper end face of the limiting block is parallel to the lower end face of the fixing ring positioning block.
The lower end face of the positioning block on the outer cylindrical surface of the fixing ring is coplanar with the lower end face of the upper pressing die pressing ring.
The utility model discloses a use method: the fixing ring of the device is sleeved on the pressing ring of the upper pressing die of the press-fitting machine, the limiting rod with the base is placed below each positioning block of the fixing ring, and when the distance from the upper end face of an oil seal to the corresponding end face of the sealing seat is unqualified in use, the height of the upper end face of each limiting rod is adjusted by the corresponding dial indicator, the moving distance of the upper pressing die in downward press-fitting is increased or reduced, and the assembly of a product meets the requirements.
The utility model has the advantages that: through this stop device, can realize using one set of mould to carry out the pressure equipment to the seal receptacle and the oil blanket of same model, and the change of the upper and lower swager that need not carry out when great difference in height appears in the oil blanket product has both improved work efficiency, has certain economic benefits again.
