Description
Technical field
The utility model relates to automobile making checkout equipment field, and in particular, the utility model is a kind of rating test ram hammer device that falls about the human body crash tests.
Background technology
Comprise that in the human body crash tests dummy's rib falls the rating test project, need make dummy's chest rib be subjected to the ram hammer bump of certain speed at vertical direction, dummy's rib produces distortion under the effect of power, inner a plurality of acceleration of chest and torque sensor will detect signal, be transferred to data acquisition system (DAS) then and change into data, fall rating test thereby finish dummy's rib.So, a kind of dropping shock hammer need be installed on the calibrating table vertical direction; In order to improve measuring accuracy, must guarantee that ram hammer vertically falls in the precalculated position by setting speed.
Patent Office of the People's Republic of China has announced a CN 2757119Y document on February 8th, 2006, name is called a kind of falling test stand, this testing table comprises column, pedestal, bears platform, is positioned at the lifting component that bears the platform top and be connected with column, and Control Component, lifting component is pneumatic-finger, vacuum cup or their combination, column is provided with lifting guideway, and lifting component and being connected of column are and being slidingly connected of lifting guideway.Pneumatic-finger by driving clamping or sticking test specimen, vacuum cup are controlled pneumatic-finger, vacuum cup abrupt release test specimen freely falls again to the height of setting, testing its crash resistance then can be impact-resistant degree.The shortcoming of this testing table is the requirement on machining accuracy height to the lifting guide rail, the processing cost height; Have stuck phenomenon after repeatedly using and take place when the lifting guide rail has wearing and tearing, the speed when causing falling changes, and influences measuring accuracy.
Summary of the invention
The utility model is for solving the lifting guide rail requirement on machining accuracy height that exists in the prior art, the shortcoming that the lifting guide rail blocks easily in fall-down test, provide a kind of accuracy requirement to the lifting guide rail almost not require, what also do not have stuck phenomenon falls rating test ram hammer device.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model comprises hammer body, frame, guide rail, frame comprises horizontal beam and newel, one end of newel links to each other with hammer body, and the other end of newel links to each other with the central point of horizontal beam and be vertical mutually; Two ends at horizontal beam are provided with through hole, and the center line of through hole is parallel with newel, and guide rail has two, pass through hole and vertical with surface level respectively; Guide rail is formed by stretching wire rope.The surface of contact of lifting device and guide rail must be greatly to guarantee that lifting device can not tilt when guide rail has only one, and the machining precision of the sliding contact surface of therefore necessary assurance guide rail and lifting device is enough high, and when guide rail was longer, its processing charges can significantly improve; When using two guide rails, slide downwards along two guide rails at the two ends of hammer body and frame (promptly being equivalent to lifting device), frame can run-off the straight, can not block yet, as long as can be competent at as guide rail with two stretching wire rope, it falls speed also can set by the free-fall velocity accurate Calculation, and rope capacity is restricted hardly, reduce the manufacturing cost of test unit, improved accuracy of detection.
As preferably, newel also is arranged with two ailerons, one end of aileron is fixedlyed connected with described newel, and the other end of described aileron is provided with second through hole, the center line of second through hole of two ailerons respectively with the central lines of the through hole at horizontal beam two ends.Aileron has the effect of fixing hammer, and makes frame and guide rail become four point locations by two point locations, has improved the stability when frame is fallen, and has improved accuracy of detection.
As preferably, newel is divided into newel, newel down, and last newel is threaded with following newel, and horizontal beam links to each other with last newel, and hammer body, aileron link to each other with following newel.When frame and guide rail become four point locations by two point locations, stability in the time of can increasing frame and fall, but be easy to generate stuck phenomenon, newel is divided into newel, following newel, last newel is threaded with following newel, and go up newel and can rotate mutually with following newel, the through hole that also promptly is installed on the horizontal beam of newel can rotate mutually with second through hole that is installed in down the aileron of newel, make four point locations that level of freedom can be arranged, thereby certain adaptive ability is arranged, avoid stuck phenomenon to produce.
As preferably, the horizontal beam center, with connect the fixedly connected suspension ring of the relative side of newel.Suspension ring can make things convenient for the lifting of frame.
As preferably, hammer body is made by steel plate, is the cylinder pie.Steel plate has higher quality and antidetonation physical strength, and processing easily.
As preferably, horizontal beam is made by steel plate.Steel plate has higher quality and antidetonation physical strength, and processing easily.
As preferably, newel is made by round steel.Steel have higher quality and antidetonation physical strength, and processing easily.
As preferably, last newel, newel is made by round steel down.Steel have higher quality and antidetonation physical strength, and processing easily.
The beneficial effects of the utility model are: adopt two wire rope to replace guide rail, significantly reduced the device fabrication cost, eliminated the stuck phenomenon when hammer body falls, the speed of landing of hammer body can accurately be set, and has improved accuracy of detection.
