Fig. 2 is a part assembled sectional view of the present utility model.

Fig. 3 is the top view of measured object mode of operation of the present utility model.

Fig. 4 is that torque sensor of the present utility model detects local enlarged diagram.

Fig. 5 is the three-dimensional exploded view of existing propeller assembly.

As Figure 1-3, the pick-up unit of destructive test of the present utility model comprises: the electronic type torque sensor of board 10, power source 12, a stationary state 20, electronic type torque sensor 20, locking are at the fixator 30 of interlock dish 25;

Board 10 includes a platform 11, and platform 11 is locked a disk 15 is housed;

Power source 12 is installed in platform 11 bottom surfaces of board 10, power source 12 is motor 13, its axle is hinged with the reductor 14 of a tool decelerating effect, make the axle 141 of reductor 14 run through disk 15 outsides above the platform 11, be equipped with a track slot 151 above the disk 15, board 10 downsides are equipped with the controller 17 of control power source 12 open and close and setting;

One end of the electronic type torque sensor 20 of stationary state is fixed on above the disk 15, and connect with controller 17, one end of torque sensor 20 is provided with a perforation that laterally runs through 21, to insert interlock dish 25, be hubbed on the interlock dish 25 on the disk 15, it is a disk, the one side is offered a fork pockets 26, to allow loose the entering of an end of torque sensor 20, aim at perforation 21 axial madial walls at fork pockets 26 and respectively be embedded with a shake-up body 27 that nearly semicircle is spherical, and the bottom surface of interlock dish 25 ring is embedded with the ball 28 of several energy elastic telescopics, utilize ball 28 to slide along rail groove 151, the central point of interlock dish 25 is penetrated with a mesopore 251, make axle 141 be positioned at this space, an intrinsic hollow form is overlapped in the outside of axle 141, the connection shaft 23 of polygonal column, the external diameter of connection shaft 23 are less than the internal diameter of mesopore 251, and connection shaft 23 passes outside the interlock dish 25.

Fixator 30 lockings are on interlock dish 25, fixator 30 is used for fixing measured object 40, its shape changes according to the shape of measured object 40, such as the embodiment that shows in the drawings, as measured object 40 is spanner, fixator 30 is provided with a matrix 31, its end face is provided with one and has the corresponding groove 32 that measured object 40 contour shapes are installed, the end face of matrix 31 is pivoted with two to three depression bars 33, depression bar 33 differs from the other end that is pivoted and is provided with locking bolt 35, with control depression bar 33 unclamp or fixing, configuration is as shown in Figure 1, 2.

When the utility model operation is implemented, measured object 40 is placed in the groove 32, as shown in Figure 3, is the fulcrum rotation by depression bar 33 with centring point 34, and across pushing down measured object 40, lock in the screw of matrix 31 correspondences by locking bolt 35 again, measured object 40 is in stationary state when detecting, as measured object 40 is spanner, and its groove 42 of pulling in order to application of force object degree of tightness is the outsides that are fixed in connection shaft 23;

Secondly, set the limiting figure (for example being the detection numerical value that measured object should reach) that torque sensor 20 detects via controller 17, restart power source 12, make reductor 14 rotations of its driving motor 13, make axle 141 turn connection shafts 23, to drive measured object 40 turns on the connection shaft 23, because measured object 40 is fixed on the fixator 30, fixator 30 is locked on the fixed torque sensor 20 by interlock dish 25 again, therefore, measured object 40 is as Fig. 3, shown in 4, the stiff end of measured object 40 just is subjected to torque sensor 20 and is fixing resistance, but give connection shaft 23 1 resistances of turn, make the ball 28 of interlock dish 25 few along the displacement that rail groove 151 slides, because interlock dish 25 and measured object 40 displacement repeatedly, touch the peritreme of the perforation 21 of torque sensor 20 when the shake-up body 27 of interlock dish 25, making torque sensor 20 detect this touches stressed, touch stressed load and reached originally and to set when detecting numerical value when predicting this, promptly pass to controller 17 so that it issues power source 12 1 signals, make power source 12 stop action, promptly finish detection; Then, measured object 40 is changed another measured object again by being disassembled on the fixator 30.

As shown in Figure 5, the bond strength that the internals 512 of adaptor 51, external member are 511 can be provided the result of detection by the utility model.As Fig. 2, shown in 4, the bore of internals 512 is sleeved on the outside of connection shaft 23, the external member 511 that is positioned at internals 512 outsides is that the device 30 that is fixed (can cooperate the adaptor profile again and changes, the non-emphasis of the present utility model of change of shape place) fixing, fixator 30 is fixed on the interlock dish 25, interlock dish 25 is subjected to the fixedly restriction of shape torque sensor 20 again, therefore power source 12 drives connection shaft 23 to drive internals 512 motions, the position of external member 511 is restricted, in making, external member 512,511 are relative motion, and (one is moving, one is quiet) state, just can predict external member 511, bond strength between the internals 512, therefore, the detection of bond strength needs between the applicable different materials of the utility model.
