The axle box bearing press-fitting machine is not suitable for trial production of products or small-batch production.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a pressure equipment frock that is used for pressure equipment rail vehicle's journal box bearing that structural design is reasonable, low in production cost, be fit for being used for product trial-manufacturing or small batch production.
In order to solve the technical problem, the utility model discloses a uide bushing, pressure equipment cover, screw rod, fender ring and hollow cylinder, the right-hand member and the uide bushing of screw rod are connected, are equipped with fastening nut at the left end of screw rod, pressure equipment cover, hollow cylinder and fender ring overlap on the screw rod from the right side to a left side in proper order, and pressure equipment cover, hollow cylinder and fender ring are in between fastening nut and the uide bushing, the left end department of uide bushing is in the pressure equipment cover.
As a further improvement, the press-fitting sleeve, the hollow oil cylinder and the baffle ring are in clearance fit with the screw rod, and the guide sleeve is in clearance fit with the press-fitting sleeve.
As the utility model discloses a further improvement, hollow hydro-cylinder includes hollow hydro-cylinder and hollow hydro-cylinder piston rod, and wherein hollow hydro-cylinder piston rod cover is on the screw rod, and the right-hand member of hollow hydro-cylinder contacts with the left end of pressure equipment cover.
The utility model has the advantages that: the utility model discloses a process to with axle box bearing pressure equipment to axletree journal designs, at first, fixes the uide bushing in axletree department, overlaps the axle box bearing on the uide bushing, uide bushing and axle box bearing inner race clearance fit, then with the right-hand member and the uide bushing fixed connection of screw rod, overlaps pressure equipment cover, hollow hydro-cylinder and fender ring on the screw rod from a right side to a left side in proper order, is equipped with fastening nut again at the left end of screw rod. The specific press fitting process comprises the following steps: and introducing high-pressure hydraulic oil into the hollow oil cylinder, enabling the hollow oil cylinder to prop against the retaining ring and extrude the press-fitting sleeve, enabling the press-fitting sleeve to extrude the inner ring of the bearing, gradually pressing the bearing onto the axle under the guiding action of the guide sleeve, enabling the rear end of the bearing of the axle box to prop against the axle shoulder of the axle, and enabling the pressure of the oil cylinder to increase rapidly and keep for 3-5 seconds to complete bearing press-fitting. The utility model has the advantages of simple structure, simple to operate, convenient operation are swift, compare in axle box bearing pressure equipment machine, and are with low costs, are fit for being used for product trial-manufacturing or small batch production.
