Abstract
The utility model discloses a hydraulic bolting device, which comprises an oil cylinder and a piston arranged in the oil cylinder. The utility model is characterized in that the lower end of the oil cylinder is provided with a press plate, the lower end surface of the press plate is provided with a connecting structure for connecting workpieces, a pull rod is arranged in the piston, the lower end of the pull rod passes out from the press plate, the pull rod is a double-head screw rod, one end of the pull rod is connected with the piston through screw threads, and a screw bolt hole used for connecting the workpieces is arranged on the press plate. Compared with the prior art, the utility model has the advantages that the utility model is provided with the press plate at the lower end of the oil cylinder, the pull rod is arranged in the piston, shaft type workpieces to be installed are connected on the pull rod, disc type workpieces to be installed are connected on the press plate, and the pull rod is driven to move upwards and downwards when the piston moves, so the shaft type workpieces can be installed in the disc type workpieces, the installation is simple, and the operation is easy.
Description
Technical field:
The utility model relates to a kind of hydraulic bolting device, specifically is a kind of erecting tools that is used for connecting axle and flange or toothed disc.
Technical background
At present for the bolt of diameter greater than 1 inch, use the common manual torque wrench and be and be difficult to its pretension, must be by the pre-clamping tool of a kind of special bolt with its pretension, that is exactly the bolt hydraulic elongator.As the patent No. is CN97234407.1 described by name " bolt hydraulic bolting device ", and it is mainly used in the bigger bolt of installation, equals the installation of axle for ring flange or chain sprocket, because be interference fit, so installation difficulty is bigger, adopt hand assembled, inefficiency more.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and the dedicated hydraulic fastening device that provides a kind of class to connect in the interference of dish class.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hydraulic bolting device, comprise oil cylinder and be arranged on in-oil cylinder piston, it is characterized in that: be provided with a pressing plate in the lower end of described oil cylinder, be provided with the syndeton that is used to connect workpiece in the lower surface of pressing plate, be provided with a pull bar in described piston, the lower end of this pull bar passes from described pressing plate.
Described pull bar is a double threaded screw, and the one end is connected with piston thread.
Described pressing plate is provided with the bolt hole that is used to connect workpiece.
Compared with prior art, the utility model has the advantages that: the utility model is provided with pressing plate in the lower end of oil cylinder, pull bar is set in piston, the shaft-like workpiece that needs are installed is connected on the pull bar, connects the disc type work that needs installation on pressing plate, and piston is when motion, the drive pull bar moves up and down, thereby shaft-like workpiece is installed in the disc type work, easy operating is installed simply.
