Abstract
The invention discloses a bolt load and torque indicator, which comprises a base, a load sensor, a connecting part, a bracket and a bolt, wherein one end part of the load sensor is fixedly connected with the base; the connecting part is fixedly connected with the other end part of the load sensor; the bracket is fixedly connected with the base; the bolt is arranged on the bracket; one end part of the bolt is threaded connection with a first fastening nut; different types of torque wrenches can be use to fasten and unfasten the nut and the bolt on the first fastening nut; and the other end part of the bolt is fixedly connected with the connecting part. The bolt load and torque indicator can display the bolt load and the bolt torque in real time through the load sensor and the torque wrench, and thus, the bolt torque can correspond to the bolt load one by one and the bolt load is quickly and exactly obtained when the bolt torque is set, or the bolt torque is quickly and exactly obtained when the bolt load is set.
Description
Technical field
The present invention relates to that a kind of to be used to test bolt be to reach the mutual indicator of setting the required torque value of load.
Background technology
In the prior art, when utilizing seal that high-pressure bottle or pipeline etc. is sealed, need load according to the rated load of seal.Common hermetically-sealed construction all adopts flange to connect, by the tight bolt of lock knob flange and seal are loaded, the required magnitude of load that provides of bolt is according to factor decisions such as pad pattern, design conditions, concrete syndetons, bolt torque Mn when the workmen calculates actual installation according to needed bolt load F can correctly reinforce.Usually the moment of torsion of bolt all is to calculate by the empirical equation of bolt load and moment of torsion, and the error that the bolt torque that often calculates exists is all bigger.
Summary of the invention
The invention provides a kind of bolt load and torque indicator that can measure the moment of torsion of bolt under corresponding load of all size quickly and easily.
For achieving the above object, the technical solution used in the present invention is: a kind of bolt load and torque indicator, it comprise base, an end be fixedly connected on load transducer on the described base, be fixedly connected on the other end of described load transducer attaching parts, be fixedly connected on support on the described base, be arranged on the bolt on the described support, one end thread of described bolt is connected with first clamp nut, being equipped with torque wrench on described first clamp nut, fixedlys connected with described attaching parts in the other end of described bolt.
Preferably, also removably be provided with positioning sleeve on the described support, described bolt is slidably disposed in the described positioning sleeve.
Preferably, described bolt thread on described attaching parts, and described bolt with end that attaching parts are connected on also threaded engagement second clamp nut is arranged.
Preferably, described base is provided with fastening bolt, and an end of described load transducer is fixedly connected on the described base by described fastening bolt.
Because technique scheme utilization, the present invention compared with prior art has following advantage: the present invention shows real-time bolt load and bolt torque by load transducer and torque wrench, thereby can realize bolt torque and bolt load corresponding one by one, and the bolt load under the bolt torque of acquisition setting fast and accurately, perhaps set the bolt torque under the bolt load.
