Description

Device of spring stiffness coefficient device for fast detecting
Technical field
The utility model relates to a kind of spring pick-up unit, particularly relates to a kind of device of spring stiffness coefficient device for fast detecting.
Background technology
Stiffness factor is the size of the elastic force that produces while describing unit form variable, if the stiffness factor value of certain spring is larger, the power needing while this spring deformation unit head being described is large.For the spring of different purposes, its stiffness factor requires different, and what have needs stiffness factor large, and what have needs stiffness factor little.
Detection springs stiffness factor is many is at present completed by tight instrument, and sense cycle is long, and for the relatively low middle quality product of accuracy requirement, this instrument not only cost is high, but also has wasted the time, cannot meet Production requirement.
Utility model content
It is low that the technical problems to be solved in the utility model is to provide a kind of cost, and easy to detect, device of spring stiffness coefficient device for fast detecting efficiently.
For addressing the above problem, the utility model provides a kind of device of spring stiffness coefficient device for fast detecting, described device of spring stiffness coefficient device for fast detecting comprises worktable, dynamometer, stretching device and contiguous block, described dynamometer and stretching device are all fixed on described worktable, and described dynamometer is positioned at one end of worktable, described stretching device is positioned at the other end of described worktable, and described contiguous block is connected with described stretching device, and the slip of described contiguous block is located on described worktable.
Further, described worktable comprises the back up pad of horizontal positioned and is arranged on four feets of four jiaos of this back up pads, and described back up pad is provided with gathering sill, and described gathering sill both sides are equipped with scale.
Further, the minimum scale value of back up pad high scale is 1mm.
Further, described contiguous block is T-shape, and described contiguous block is provided with hook, and the both sides of described contiguous block are provided with tuning drive gear.
Further, described stretching device is hydraulic jack.
The utility model device of spring stiffness coefficient device for fast detecting is simple in structure, in use, first read the scale numerical value of contiguous block high scale pointer indication, and then stretching or Compress Spring are to predeterminated position, now read again the value of thrust on scale numerical value and the dynamometer of tuning drive gear indication, can calculate the stiffness factor of detection springs, it is convenient, fast that the utility model device of spring stiffness coefficient device for fast detecting detects stiffness factor, and cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model device of spring stiffness coefficient device for fast detecting preferred embodiments.
Fig. 2 is the structural representation of worktable.
Fig. 3 is the structural representation of contiguous block.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model device of spring stiffness coefficient device for fast detecting preferred embodiments comprises worktable 1, dynamometer 2, stretching device 3 and contiguous block 4.Described dynamometer 2 and stretching device 3 are all fixed on described worktable 1, and described dynamometer 2 is positioned at one end of worktable 1, described stretching device 3 is positioned at the other end of described worktable 1, described contiguous block 4 is connected with described stretching device 3, and described contiguous block 4 slides and is located on described worktable 1, and described contiguous block 4 can slide by relatively described worktable 1.
Described worktable 1 comprises the back up pad 11 of horizontal positioned and is arranged on four feets 12 of 11 4 jiaos of this back up pads, and described back up pad 11 is provided with gathering sill 111, and is equipped with scale in these gathering sill 111 both sides.The minimum scale value of this scale is 1mm, and the numerical value that it is read is more accurate, and final measurement is more accurate.The slip of described contiguous block 4 is located in this gathering sill 111.
Described stretching device 3 is hydraulic jack.In other embodiments, stretching device 3 can also adopt cylinder etc.
As shown in Figure 3, described contiguous block 4 is T-shape, and described contiguous block 4 is provided with hook, and the both sides of described contiguous block 4 are provided with tuning drive gear 41, is convenient to read the numeral on scale.
Particularly, described dynamometer 2 and described stretching device 3 are all fixed in described back up pad 11, and described dynamometer 2 and described stretching device 3 lay respectively at the two ends of described back up pad 11, described contiguous block 4 is fixing with described stretching device 3, be that contiguous block 4 is fixed with the piston on hydraulic jack, and contiguous block 4 slips are arranged in the gathering sill 111 in back up pad 11.
When use, the two ends of spring 5 to be measured are separately fixed to the hook on hook and the dynamometer 2 on contiguous block 4, after fixing, record the numerical value of tuning drive gear 41 indications on contiguous block 4, after to be recorded getting well, make stretching device 3 drive contiguous block 4 to move, its spring 5 to be measured is stretched, contiguous block 4 stops moving after moving predeterminable range, record the now numerical value of tuning drive gear 41 indications, so can calculate the displacement of contiguous block 4, the displacement of contiguous block 4 is the deflection of this spring 5 to be measured, read dynamometer 2 upper pulling force numerical value simultaneously, just can calculate the stiffness factor of spring, thereby judge that whether this spring is qualified.In this process, needing to keep this spring 5 to be measured is the non-state that is forced to.It is convenient, fast that the utility model device of spring stiffness coefficient device for fast detecting detects stiffness factor, and cost is low.
These are only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure that utilizes the utility model instructions and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner within scope of patent protection of the present utility model.
