Description
Technical field
This utility model relates to Machine Design, particularly relates to a kind of little magnitude high flex point impact test apparatus.
Background technology
Impact refers to that object occurs the biggest velocity variations in a short period of time or carries out unexpected energy conversion, impact
The feature of excitation is that the time is short, and acceleration is big, and product is typically stored, transported, cargo handling process can be caused dress by different impulsive forces
Standby destruction.In order to examine product therefore laboratory simulation impact test to be the important means that equipment is examined.Existing impact rings
Answer the response spectra that frequency domain experimental condition important parameter spectrum shape flex point is 800Hz～1600Hz that testing equipment can be carried out, now
Certain important type product requires the amount of carrying out extremely 500g, flex point 2000Hz～the Shock Environmental Condition of 3000Hz, laboratory equipment
This experimental condition cannot be completed.
Utility model content
In view of this, the purpose of this utility model is to propose a kind of little magnitude high flex point impact test apparatus, it is achieved should
Experiment condition, it is ensured that type product impact test is smoothed out.
The little magnitude high flex point impact test apparatus provided based on above-mentioned purpose this utility model, including impact part, its
Being characterised by, impact part includes impact head, transition piece, connecting rod and bullet torr, and wherein impact head is first threadeded with transition piece,
Being connected with the threaded one end of connecting rod, the other end of connecting rod is embedded in bullet torr again.
Further, one end of impact head is shock surface, and its sidewall is uniformly distributed multiple groove, between adjacent two grooves
Sidewall is multiple equally distributed planes.
Further, the impact head other end is metal tube, and its metal tube outer wall is provided with screw thread.
Further, transition piece radially has circular groove, and the upper side of circular groove is acclivitous plane, and downside is downward
The inclined-plane tilted.
Further, connecting rod is designed with different length.
Further, the groove of impact head sidewall is 6-24, the sidewall between adjacent two grooves be 3 equally distributed
Plane.
It is from the above it can be seen that the little magnitude high flex point impact test apparatus that this utility model provides, simple and practical,
Easy for installation, and meet special experiment condition, improve the test capability of impact test equipment simultaneously.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and
Referring to the drawings, this utility model is further described.
It should be noted that the statement of all uses " first " and " second " is for district in this utility model embodiment
The entity of point two same names non-equal or the parameter of non-equal, it is seen that " first " " second " only for the convenience of statement,
Should not be construed as the restriction to this utility model embodiment, this is illustrated by subsequent embodiment the most one by one.
With reference to shown in Fig. 1, it is shown that the impact portion of the little magnitude high flex point impact test apparatus of this utility model embodiment
Part structure chart.Impact part includes impact head 1, transition piece 2, connecting rod 3 and bullet torr 4, wherein impact head 1 elder generation and transition piece 2 spiral shell
Stricture of vagina connects, then is connected with the threaded one end of connecting rod 3, and the other end of connecting rod 3 is embedded in bullet torr 4.
With reference to shown in Fig. 2 a and Fig. 2 b, it is shown that the profile of the impact head of this utility model embodiment and top view.Punching
Tap the head 1 one end be shock surface, its sidewall is uniformly distributed 6-24 groove, the sidewall between adjacent two grooves be 3 uniformly
The plane of distribution.Impact head 1 other end is metal tube, and its metal tube outer wall is provided with screw thread, and wherein Major Diam is 24mm, pitch
For 2mm, can install easily with transition piece 2 and connecting rod 3 and dismantle.In the present embodiment, impact head 1 total length is
83mm, wherein metal tube length is 58mm.This utility model, by being adjusted impact head 1 structure, alleviates impact part
Weight.
With reference to shown in Fig. 3, it is shown that the profile of the transition piece of this utility model embodiment and top view.Transition piece 2 edge
Radially having circular groove, the upper side of circular groove is acclivitous plane, and downside is downward-sloping inclined-plane.Transition piece 2 inwall
Being provided with screw thread, in the present embodiment, Major Diam is 24mm, and pitch is 2mm, and transition piece 2 height is 33mm.This utility model passes through
Transition piece 2 structure is improved, further mitigates the weight of impact part.
With reference to shown in Fig. 4, for the profile of the connecting rod of this utility model embodiment.Connecting rod 3 designs different length,
Reduce the impact stroke of impact head.The inwall of connecting rod 3 is provided with Major Diam 24mm, the screw thread of pitch 2mm.In the present embodiment,
