Accompanying drawing 4 is the schematic diagram of embodiment 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As shown in Figure 1 to Figure 3, a kind of weight freely falling body clashes into the stationary installation of chair testing machine, comprise base 1, seat 2 to be tested is located on base, weight block 6 is provided with above seat, conveniently seat is fixed on base, the horizontal slide rail 12 that described base is provided with 2 longitudinal directions and establishes, slide in horizontal slide rail and have two fixed mounts 7, after two front chair legs of described seat and two, chair pin is separately fixed on two fixed mounts, article two, fixed mount can move forward and backward, can regulate according to different chair foot spacing, fixed form between chair pin and fixed mount can be welded and fixed, also can be detachable fixing, after adopting the technical program, seat is first fixed on fixed mount by this programme, then fixed mount is fixed on base, utilize the adjustability of horizontal slide rail, the fixed mount of different spacing can be installed on base, thus expand the scope of application of this test machine, namely dissimilar seat can be installed, as long as the longitudinal separation of chair pin is in the adjustable extent of base horizontal slide rail, all Fast Installation can be realized, and can under fast dismantling after testing.
As preferably, scheme in Fig. 3 is detachable fixing, described fixed mount there is the fixed jack 71 of more than 2, fixed jack sidewall is provided with trip bolt 711, chair pin to insert in fixed jack and fixes with trip bolt, because different seats, the diameter of steel tube of its chair pin is also different, so in this programme, fixed jack on every root fixed mount is 8, every side is 4, the diameter of fixed jack is respectively 6mm, 8mm, 10mm, 12mm, different jacks can plug in the chair pin of different sizes, fixed mount two side ends is provided with longitudinal direction and the mounting hole 72 established in addition, the screw be fixed to by fixed mount on base is provided with in mounting hole.
In addition, base divides laying to be provided with 2 root posts 11 in the both sides of seat, column is provided with the slide rail of Vertical dimension, slide in slide rail and have draw runner, rack and rinion adjustment is provided with between column and draw runner, the stroke that rack and rinion adjustment regulates is larger, crossbeam 3 is fixed with between described two draw runners, flexible gas bar 4 is provided with in the middle of crossbeam, sucker 5 is connected with below flexible gas bar, sucker comprises sucker 51 and lower sucker 52, upper sucker energising produces strong magnetic, after power-off, magnetic disappears, on, a rope is had to connect between lower sucker, wherein go up sucker to be connected with flexible gas bar, upper sucker is with the oscilaltion of flexible gas bar, weight block 6 described in lower sucker connects, when upper sucker produces magnetic, hold with sucker under general who has surrendered under flexible lower beam, then rise together, when upper sucker magnetic disappears, lower sucker declines with weight freely falling body, strike on seat, described cross rail top is provided with upper bracket 31, described flexible gas masthead portion is connected with upper bracket, the micromatic setting for regulating flexible gas bar to be elevated is provided with in upper bracket, the stroke that micromatic setting regulates is less, precision is high, after adopting the technical program, the device that two kinds regulate weight falling head is provided in this programme, be respectively rack and rinion adjustment and micromatic setting, when practical adjustments, can rack and rinion adjustment be first adopted tentatively to regulate on a large scale, the stroke regulated is larger, etc. when being transferred to close to intended target height, micromatic setting can be adopted slowly to be adjusted to intended target height, the speed regulated can be ensured, the precision regulated can be ensured again.
As preferably, described micromatic setting is ball screw framework, upper bracket is provided with trimming hand wheel 311, described flexible gas bar is connected with the screw rod in ball-screw, ball screw framework is the mechanical mechanism of comparative maturity, when rotating trimming hand wheel, drive screw turns, slide block during bolt rotary on drive screw slides up and down, slide block is connected with flexible gas bar, indirect driving is stretched the oscilaltion of gas bar, flexible gas bar self possesses Telescopic, what micromatic setting regulated is the initial position height of flexible gas bar, as preferably, described rack and rinion adjustment is gear & rack structure, described draw runner is provided with tooth bar, described column is provided with coarse adjustment handwheel 111, coarse adjustment handwheel is connected with gear, the stroke that gear & rack structure regulates is larger, structure is also comparatively simple, column sidewall described is in addition provided with pin-and-hole 112, pin-and-hole interpolation has the latch for draw runner and column being fixed, and after utilizing rack and rinion adjustment to complete preliminary adjustment, draw runner and column is fixed with latch, thus fixing horizontal depth of beam, the number of pin-and-hole has multiple.
In addition, the target of this programme test is the impulsive force durable test that weight clashes into seat, and the disposable impact test of non-test, therefore the weight block surface of clashing into can not too rigidity, not so easy seat surface to be smashed, preferably, described weight block is double-decker, internal layer is derby, and skin is rubber covering, or described weight block is sand bag.
As shown in Figure 4, for another kind of embodiment, be that described rack and rinion adjustment is hydraulic pump with the difference of embodiment 1, described column is provided with hydraulic pump control panel 113, regulating with hydraulic pump regulates more laborsaving compared to rack-and-pinion, utilize hydraulic pump to regulate simultaneously and also eliminate the mechanism fixing draw runner with latch, directly with the height of the pressure locking draw runner of hydraulic pump, and in the present embodiment, increased horizontal depth of beam display screen 32, when utilizing hydraulic pump to regulate, horizontal depth of beam can be presented on height display screen intuitively.
Below only just the present invention preferably example be described, but can not be interpreted as it is limitations on claims.The present invention not only limits to and above example, and its concrete structure allows to change, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
