Accompanying drawing explanation
Fig. 1 is the structural representation of portable torque spanner calibrating and measuring device of the present invention；
In figure: 1-measurement apparatus, 2-reinforcing joint, 3-rotating shaft support plate, 4-fluid bearing, 5-hydraulic power source, 6-power list
Unit, 7-levelling device, 8-casing, 9-rotating shaft.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
As it is shown in figure 1, the present invention includes square box 8, in casing 8, it is provided with power supply unit 6, hydraulic power source 5, fluid bearing
4 and vertically-mounted rotating shaft 9, the outer end face of casing 8 is provided with afterburning joint 2 and measurement apparatus 1, and the upper end of rotating shaft 9 passes case
Body 8 also fixing with afterburning joint 2 is connected, is detachable fixed structure between reinforcing joint 2 and rotating shaft 9, the torsion of measurement apparatus 1
Power is measured end and is connected to the upper end of rotating shaft 9, and the lower end of rotating shaft 9 is arranged in fluid bearing 4, with hydraulic power source 5 while of power supply unit 6
Electrically connecting with measurement apparatus 1, the flow stream pressure end of hydraulic power source 5 is connected with the flow stream pressure end of fluid bearing 4.
So that rotating shaft 9 in rotation process without departing from position, be provided with rotating shaft 9 gripper shoe 3, rotating shaft 9 in casing 8
Fagging 3 is provided with axis hole, and rotating shaft 9 is enclosed within the axis hole of rotating shaft 9 gripper shoe 3, deposits between the axis hole of rotating shaft 9 and rotating shaft 9 gripper shoe 3
In gap.The top of casing 8 is provided with axis hole, and the upper end of rotating shaft 9 passes in the axis hole of casing 8, rotating shaft 9 and the axle of casing 8
Gap is there is between hole.
In order to mate the torque spanner of quantitatively record connection tightness, afterburning joint 2 is regular hexagon structure.
In order to eliminate deviation of directivity when the uneven of Mass Distribution and calibrating moment applying, the bottom of casing 8 is provided with
Some levelling devices 7, can be adjusted to level by casing 8, are designed with three levelling devices 7 in figure.
The work process of portable torque spanner calibrating and measuring device of the present invention is as follows:
