Description
Technical field
The utility model relates to three roller centring machine repair apparatus, relates in particular to a kind of three roller centring machine steel bushing repairing auxiliary devices.
Background technology
Along with steel and iron industry production equipment high strength day by day, the requirement that equipment is installed improves day by day at present, and this overhauls industry to us and how to improve overhaul efficiency, strengthens work capacity and has higher requirement.As the three roller centring machines that in pipe production line, often use, frequent in order to cooperate it to use, the characteristics that working strength is high, its rotary part has all been installed steel bushing, and the installation of steel bushing all uses special binders to carry out fixing, and these equipment difficulty in the process of changing is increased greatly.If use common hand disassembly method, incompatibility operating position all concerning dismounting precision and ability to dismantle.
Summary of the invention
The utility model is intended to solve that existing three roller centring machine steel bushing dismounting precision can't guarantee, traditional maintenance technology falls behind, the technical problem of inefficiency of production, and a kind of three roller centring machine steel bushing attaching/detaching apparatus are provided.The utility model can guarantee steel bushing dismounting precision, and is swift to operate, increases work efficiency.
The utility model is achieved in that
A kind of steel bushing attaching/detaching apparatus of three roller centring machines, it comprises the hydraulic jack that has oil supply system, described hydraulic jack tail end is fixedly connected with back-up block, and its push rod end is fixedly connected with the gland piece.
Described three roller centring machine steel bushing attaching/detaching apparatus, described gland piece is the cylinder that has ladder, the end face of its enlarged diameter section connects hydraulic jack push rod end.
Described three roller centring machine steel bushing attaching/detaching apparatus, the diameter of described gland piece enlarged diameter section is greater than three roller centring machine steel bushing external diameters, and the steel bushing internal diameter of its reduced diameter section diameter and three roller centring machines is a matched in clearance.
The utility model can be realized the dismounting to three roller centring machine steel bushings, because stressed uniform and stable, unloading process is reduced to 0% to the spoilage of steel bushing and body by original 40%, guarantees the dismounting precision; Simple and efficient to handle, efficient has improved more than 5 times.
Description of drawings
Below, in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the utility model working state schematic representation;
The specific embodiment
As shown in Figure 1, a kind of steel bushing attaching/detaching apparatus of three roller centring machines, it comprises the hydraulic jack 3 that has oil supply system 4, described hydraulic jack tail end is fixedly connected with back-up block 2, and its push rod end is fixedly connected with gland piece 1.
Described three roller centring machine steel bushing attaching/detaching apparatus, described gland piece 1 is for having the cylinder of ladder, and the end face of its enlarged diameter section connects hydraulic jack 3 push rod ends.
Described three roller centring machine steel bushing attaching/detaching apparatus, the diameter of described gland piece 1 enlarged diameter section is greater than three roller centring machine steel bushings, 6 external diameters, and steel bushing 6 internal diameters of its reduced diameter section diameter and three roller centring machines are matched in clearance.
