Abstract
The invention relates to a pre-tightening force loading device which comprises a pressing rod, a power device, a locking device and a support. The power device is arranged above the support, one end of the pressing rod serves as a connecting end, and the other end of the pressing rod penetrates through the power device and is movably fixed inside the support through the locking device. The problem of axial pre-tightening force loading between two connecting parts is solved, and the pre-tightening force loading device is simple in structure and good in applicability. The weight of the whole device is not greater than 10 kg, and the pre-tightening force loading device is small in size, light in weight and good in machinability. The loading demand of 0.1-100 kN pre-tightening force can be met, and a loading range is wide.
Description
Technical field
The present invention relates to a kind of external force bringing device, particularly relate to a kind of pretightning force charger, be applicable to load certain axial pre tightening force to some product.
Background technology
When connecting separation Fire load, need be connected the two portions together by connecting screw rod, for ensureing connection reliability between two attaching parts, certain axial force need be applied to connecting rod, but the current unspecial device to applying axial pre tightening force between two attaching parts.
