Background technology
With the development of science and technology, the application of torque multiplier and hydraulic spanner is more and more extensive, it is mainly used in the fields such as Aero-Space, wind-powered electricity generation, oil, chemical industry, chemical machinery, Large-Scale Equipment manufacturing industry, these industries can all use a large amount of large-sized bolt nut connections, the moment of torsion tightened needs to reach thousands of to up to ten thousand Nm, this is that common manual or electro-pneumatic torque wrench is not reached, therefore can only carry out installation operation by the torque multiplier of bigger screw-down torque and hydraulic spanner.Torque multiplier and hydraulic spanner common feature are that the torque ratio of output is larger, generally thousands of to tens of thousands of Nm.It is not both torque multiplier and obtains larger output torque by smaller input torque, and hydraulic spanner is then manually or electric hydraulic station provides power, exports larger moment of torsion.At present, the calibrating installation for being now able to be detected to torque multiplier and hydraulic spanner is not yet gone out.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of simple structure, the detection means of the hydraulic spanner that easy to use, detection range is wide, detection efficiency is high.
In order to solve the above-mentioned technical problem, the detection means of hydraulic spanner of the invention, cabinet including base and above base, guide rail is provided with base, the bottom of cabinet is provided with the guide rail slide block for making cabinet be moved horizontally on guide rail, the side of base is provided with a motor, and a leading screw is connected with an output shaft for motor, and a leading screw setting supporting with guide rail simultaneously can drive guide rail to move in the horizontal direction；Cabinet has the splined shaft being vertically arranged, there is horizontally disposed reduction box the side of cabinet, the rear end of reduction box extend into casing and is connected with splined shaft, the front end of reduction box is provided with input torque sensor, enclosure top is provided with and No. two motors that reduction box is lifted is connected and can made with splined shaft, the output torque sensor in front of cabinet is additionally provided with cabinet, the both sides of output torque sensor are provided with reaction stop.
There are No. two leading screws being vertically arranged in the cabinet, No. two leading screws are driven by No. three motors positioned at enclosure top.
Output torque sensor installation seat corresponding with input torque sensing station is provided with below the base, output torque sensor is arranged on output torque sensor installation seat.
After above-mentioned structure, because the front end of reduction box is provided with input torque sensor, the corresponding output torque sensor of input torque sensor is additionally provided with base, the cabinet for setting simultaneously can be moved horizontally by guide rail on base, reduction box can be moved up and down, thus enough spaces are made it have to detect large-scale torque multiplier and hydraulic spanner, during detection, torque multiplier to be measured or hydraulic spanner are placed between input torque sensor and/or output torque sensor, No. two motors drive splined shaft to rotate, slowed down by gear reduction box again and moment of torsion is transferred to load, its structure setting is simple, it is easy to use, concentric torque multiplier can be realized, the detection of eccentric torque multiplier and hydraulic spanner, solve wide range hydraulic spanner, the calibration problem of torque multiplier.
