Accompanying drawing explanation
Fig. 1 is the structural representation of the percussion mechanism according to the utility model first embodiment;
Fig. 2 is the structural representation according to ram hammer in the utility model first embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each embodiment of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
First embodiment of the present utility model relates to a kind of percussion mechanism, specifically as shown in Fig. 1 ~ 2, comprises: support 1, clip arm 2, transparent hollow cylinder 3, stationary fixture 4, cross bar 5, hook 6 and ram hammer 7.
Wherein, clip arm 2 is flexibly connected with support 1, and this clip arm is used for clamping transparent hollow cylinder 3.Specifically, clip arm 2 is Movable clamp arm, can move up and down along support 1.The height of clip arm 2 can determine according to the length of transparent hollow cylinder 3 and target to be tested.
Transparent hollow cylinder 3 adopts plastic material, and the center of stationary fixture 4 is aimed at center.The position of the tup of ram hammer can be observed, so that according to the position of target adjustment tup to be tested through transparent hollow cylinder 3.Meanwhile, the transparent hollow cylinder 3 of plastic material is not easy fragmentation in test process, and material is easy to get, cheap, can reduce the cost of test, is the ideal chose of transparent hollow cylinder 3.
Cross bar 5 is fixedly connected with support 1, can move up and down along support 1, and is positioned on clip arm 2; This cross bar 5 is provided with hook 6, and hook 6 is fixedly connected with cross bar, for hanging ram hammer 7.
The target to be tested (depending on going out) that ram hammer 7 is fixed to stationary fixture 4 for freely falling body from transparent hollow cylinder 3, to test the impact strength of target to be tested.Specifically, ram hammer 7 comprises: tup 73 and hammer handle 72; Tup 73 is fixedly connected with by screw thread with hammer handle 72, can dismantle; Tup 73 overlaps with the perpendicular bisector of hammer handle 72; Tup 73 is spherical socket cap, and hammer handle 72 is right cylinder; The afterbody of hammer handle 72 is provided with link 71; Link 71 is fixedly connected with by screw thread with hammer handle 72; Hammer handle 72 can be hung on hook 6 by link 71.
By screw thread, tup is fixedly connected with hammer handle, connects reliable, difficult drop-off in test process, and simple, be easy to promote.The hammer handle of cylindrical shape, rotational symmetry degree is high, selects the hammer handle of cylindrical shape, when treating test target and testing, can improve ram hammer stability in the process of freely falling body, and then improves the reliability of test.
Above-mentioned percussion mechanism is used to test the process of target to be tested as follows:
