Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figures 1 to 3, Multifunction test animal impact machine, including stand, it is arranged at the spring on stand top and has an effect device, what device of having an effect with spring was connected rams, and is positioned at the backing plate 15 of lower section of raming, and is provided with pressure transducer 1 bottom described backing plate.
Using method is as follows: be exposed on backing plate by required impact object, it is fixed, both hands upwards slowly pull and ram, compression spring is had an effect device, and then moment loosens and rams, and has an effect the restorable process of device at spring, produce strong impetus and promote the object of study ramed on rapid strike backing plate, after shock, pressure transducer sensing impact force, thus measuring the pressure size of reality.
Specifically, described spring is had an effect the hollow circular cylinder that device includes being connected with stand, is arranged at the spring 2 in hollow circuit cylinder body；Described hollow circular cylinder both sides have strip through hole at axial direction, and are provided with scale at strip through hole edge；Be provided with mean for raming in the middle of bottom described hollow circular cylinder through cylindrical hole；Described one end of raming is positioned at hollow circuit cylinder body and is positioned at below spring, and the other end is positioned at hollow circuit cylinder external body.
By above-mentioned setting, spring is positioned at hollow circular cylinder inner top, and the top ramed and spring contact, when operator will ram and move up, spring then can be compressed, after loosing one's grip, elastic force due to spring, ram then can sharp downward movement, thus the thing to be hit clashed on backing plate, easy to operate.It addition, adopt above-mentioned setting, it is possible to change spring, selecting suitable spring according to different experiments demand, thus meeting demand, improve the suitability of the present invention.Owing to being provided with scale on hollow circular cylinder, this makes it possible to measure the length that spring is compressed, thus calculating the elastic force of spring；Scale also can ensure that to ram whether be in level simultaneously, thus improving shock accuracy and stability, reduces deviation.
In order to better realize the present invention, there is bottom described hollow circular cylinder certain thickness, when so raming through cylindrical hole, the track ramed can be defined by cylindrical hole, it can be ensured that the movement locus ramed, because bottom has certain thickness, so cylindrical hole necessarily has certain length, this makes it possible to make to ram is move straight down along cylindrical hole, it is possible to reduce the deviation of knockout process, improves the accurate and stable of shock.
Specifically, described raming includes being arranged in hollow circuit cylinder body and being positioned at the pedestal 5 below spring, it is connected with pedestal and two ends extend through the handlebar 6 of strip through hole, it is arranged at the trip rod 7 being connected below pedestal and with pedestal, and is arranged at trip rod bottom and is positioned at the impact head 8 of hollow circuit cylinder external body；Described trip rod runs through cylindrical hole.
By arranging pedestal, it is possible to well spring is compressed, the specifically upper surface of pedestal and spring contact, ram when moving upward, pedestal will by spring-compressed so that spring possesses elastic force；Handlebar is to facilitate operator to grip, and moves up thus pulling to ram, and handlebar matches with scale, it is possible to know whether pedestal exists inclination accurately, specifically whether is stored in same scale according to handlebar two ends and judges.Above-mentioned trip rod coordinates with cylindrical hole, it is possible to limit the movement locus ramed, and reduces the deviation of knockout process.
What deserves to be explained is, described impact head can be arranged to pie according to practical situation, spherical etc..
