Fig. 2 is vertical view of the present invention.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below with reference to this specification attached drawing to this hair
It is bright to be described in further detail.
Embodiment 1：As shown in attached drawing 1~2, a kind of stretching force detecting apparatus, it includes pedestal 1, cylinder 4 and tensiometer 2,
One end of pedestal 1 is fixedly arranged above tensiometer 2, and the other end of pedestal 1 is fixedly arranged above cylinder 4, and there is connection in one end of tensiometer 2
First 13, one end of cylinder 4 is connected with connector 2 14, is also fixedly connected with sliding rail 8 on the pedestal 6, on the both ends of sliding rail 8
Symmetrical two fixtures 3 are respectively equipped with, the fixture 3 is connect with connector 1 and connector 2 14 respectively.
Further, fixture 3 includes sliding block 10, lower clamp plate 9 and upper clamp plate 6, and sliding block 10 is slidably connected on sliding rail 8, under
Clamping plate 9 is connect by bolt with sliding block 10, and the top of lower clamp plate 9 is fixedly connected with upper clamp plate 6, is equipped in the both sides of upper clamp plate 6
Symmetrical two trip bolts 7 are equipped with cushion block 11 in the lower section of upper clamp plate 6, spring 12 are equipped between cushion block 11 and lower clamp plate 9.
Further, lower clamp plate 9 is L-type structure, has been respectively fixedly connected with connector 1 in the side of lower clamp plate 9 and has connected
Connector 2 14.
Further, spring 12 is located at the underface of trip bolt 7.
Further, sliding rail 8 is located in overlook direction on same axis with connector 1 and connector 2 14.
Pedestal 1 is the installation carrier of the component in stretching force detecting apparatus of the present invention；Tensiometer 2 is pulling force and thrust measurement
Display instrument is fastened on by four bolts on pedestal 1, while the connector 1 on tensiometer 2 is fixed on fixture 3, is made
It becomes rigid connection body；Fixture 3 is the holding carrier for detecting object, is bolted on the sliding rail 8 of pedestal 1, is
Central axial direction is connected, and four trip bolts 7 of top are to tighten unit, can be well by detection object and fixture
3 fix, and will not in test cause loosening, shift phenomenon；Cylinder 4 is fixed on by clamping screw on pedestal 1, can be into
Row pulling force drives, and can also carry out thrust driving.
On the inner opening wall of heretofore described fixture 3（On notch between cushion block 11 and lower clamp plate 9）For salient point
