Embodiment
Below in conjunction with drawings and Examples the utility model is further specified: the use dynamics pick-up unit that as shown in Fig. 1,2,3, is used for the UT (Ultrasonic Testing) angle probe, comprise the main casing 15 that is placed in outside the angle probe 14 and be erected at main casing 15 outer field mobiles 16, described main casing 15 comprises the main casing riser 13 outside the angle probe 14, and the main casing top board 12 above the angle probe 14.Main casing directly contacts with the UT (Ultrasonic Testing) angle probe, but and be loose fit between the angle probe, be that main casing top board 12 by the angle probe top passes over perpendicular to the power of measured workpiece surface direction.
As shown in Figure 2, described mobile 16 is provided with mobile's riser 1 of mobile's top board 6, main casing both sides, and the middle part of described mobile top board 6 is provided with top board through hole 8, and the cavity between main casing top board 12 and mobile's top board 6 is provided with:
1. with the fixing main casing Roofing slab 11 in main casing top board 12 middle parts,
2. pass the zeroing bolt 7 of top board through hole 8,
3. be around in the outer spring 9 of screw rod of zeroing bolt 7,
4. with the fixing tooth bar 4 of main casing 15,
5. with tooth bar 4 meshed gears 3,
The diameter of top board through hole 8 makes mobile's top board 6 to have along the degree of freedom of bolt axis direction with respect to zeroing bolt 7 greater than the screw diameter of zeroing bolt 7.Therefore when mobile's top board 6 relative main casings had relative motion, the gear 3 in the mobile had relative rolling with the tooth bar 4 that is connected with main casing 15.
The two end axles of described gear 3 is rotating respectively be embedded in mobile's riser 1 and with mobile 16 relatively-stationary supporting plates 5 in, the gear end axle that is embedded in mobile's riser 1 passes outside mobile's riser 1, and a dynamometry pointer 2 is fixed in this end axle outer end.The amount of exercise of mobile's top board 6 relative main casings can be observed from the amount of spin of dynamometry pointer 2.
Described main casing Roofing slab 11 middle parts are provided with screw 10, and described zeroing bolt 7 is threaded with the screw 10 of main casing Roofing slab 11.Zeroing bolt 7 plays the effect of regulating the pointer initial position, to prevent pointer existing reading when the dynamometry not.
Leave the gap between described main casing Roofing slab 11 and the main casing top board 12, leave the space for the adjustment of zeroing bolt.As a kind of embodiment, also can make main casing Roofing slab 11 and main casing top board 12 become the integral body that adequate thickness is arranged, leave enough surpluses for the adjusting of zeroing bolt.
Earlier probe is inserted in device inside during use, the notch part of main casing is facing to wiring place of angle probe.In the Non-Destructive Testing training, the operation in the time of should as far as possible keeping auxiliary to no device is similar, just can play the effect that helps to cultivate feel.So thumb acts on a side during operation when training, and forefinger and middle finger act on opposite side, thumb and forefinger, middle finger act on respectively on the main casing external activity body riser.And in the actual detected process, can select above mode, more recommend with following mode, that is: during operation, forefinger acts on mobile's top board 6 of main casing outside, and thumb and middle finger act on respectively on the both sides mobile riser, thumb acts on a side, and middle finger is at opposite side.Use the size of dynamics afterwards according to the reading standard of dynamometry pointer.
