Summary of the invention
The utility model provides a kind of vibration test fixture, can solve because vibration test fixture applicable performance difference causes vibration test efficiency low and the problem that cost is high.
In order to achieve the above object, embodiment of the present utility model adopts following technical scheme:
A kind of vibration test fixture, arrange on a vibration table, described vibration test fixture comprises:
Circular bottom plate, level is fixedly installed on described shake table upper surface, and the plate face of described circular bottom plate vertically offers multiple first through hole;
Portable plate, plate face vertically offers multiple second through hole, by the moving screw matched with described first through hole and described second hole size, described portable plate level is fixedly installed on the top with described circular bottom plate, between described portable plate and described circular bottom plate, there is a headspace for clamp assay part.
Alternatively, the plate face of described circular bottom plate vertically offers multiple third through-hole, pass described third through-hole by bolt thus described circular bottom plate is fixedly installed on described shake table upper surface.
Alternatively, multiple described third through-hole is uniformly distributed formation two donuts in described circular bottom plate, and the center of described circular bottom plate is the center of circle of described annulus.
Alternatively, each described annulus is distributed with 8 described third through-holes.
Alternatively, described portable plate comprises two pieces, and portable plate described in every block connects two described moving screws.
Alternatively, two of described moving screw has screw thread, and described moving screw is fixed respectively by the nut matched through after described first through hole and described second through hole.
The beneficial effects of the utility model: in vibration test fixture of the present utility model, circular bottom plate and portable plate all offer multiple through hole, to be matched with corresponding through hole by moving screw again thus portable plate be fixed on the position that circular bottom plate is applicable to, the through hole of formula of gathering makes the washability of fixed position between portable plate and circular bottom plate large, be applicable to the testpieces of different volumes, applicability is strong, reusable, cost-saving.

Detailed description of the invention
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.
As shown in Figures 1 to 4, vibration test fixture of the present utility model, is arranged on a vibration table, for clamp assay part.Vibration test fixture at least comprises circular bottom plate 1 and portable plate 2.
Particularly, circular bottom plate 1 level is fixedly installed on shake table upper surface; The plate face of circular bottom plate 1 vertically offers multiple first through hole 11.Suitable selection can be carried out as required in the quantity of the first through hole 11 and position, such as, radially can be evenly arranged centered by the center of circle of circular bottom plate 1, to ensure the intensity of circular bottom plate 1.
It is top that portable plate 2 is arranged on circular bottom plate 1, and has a headspace between circular bottom plate 1 for clamp assay part.Particularly, be on the plate face of portable plate 2, vertically offer multiple second through hole 21, then by the moving screw 3 matched with the first through hole 11 and the second through hole 21 size, portable plate 2 level be fixedly installed on the top with circular bottom plate 1.
Vibration test fixture of the present utility model can also vertically offer multiple third through-hole 12 on the plate face of circular bottom plate 1, and, usually be all offer bar hole or through hole on a vibration table, by bolt through the through hole on third through-hole 12 and shake table, thus circular bottom plate 1 is fixedly installed on shake table upper surface.Further, as shown in dotted portion circular in Fig. 3, multiple third through-hole 12 is uniformly distributed formation two donuts in circular bottom plate 1, the center of circular bottom plate 1 is the center of circle of described annulus, and each described annulus is distributed with 8 described third through-holes 12, the stability that circular bottom plate 1 is connected with shake table can be strengthened.
In vibration test fixture of the present utility model, portable plate 2 can comprise two pieces, and every block portable plate 2 connects two moving screws 3.It should be noted that, moving screw 3 can be multiple applicable screw rod, and such as one has screw thread or two to be all screw threads.In the present embodiment, two of moving screw 3 has screw thread, and moving screw 3 is fixed respectively by the nut matched through after the first through hole 11 and the second through hole 21, and dismounting can be made lighter, improves test efficiency.
When vibration test fixture of the present utility model uses, first that circular bottom plate 1 is fixing on a vibration table by middle two circles 16 the second through holes with bolt; Then block the both sides of a testpieces termination with two moving screws 3, be fixed in circular bottom plate 1; Pass two moving screws 3 by portable plate 2 from upper end again, and be fixed on above testpieces with nut, packing ring; Finally use the other end of same method fixation test part, thus testpieces is fixed.
Vibration test fixture of the present utility model, circular bottom plate 1 and portable plate 2 offer multiple through hole, the through hole (comprising the through hole of circular bottom plate 1 and portable plate 2) that moving screw 3 can be spirally connected close with testpieces, can carry out fastening to testpieces fast, saves man-hour.In addition, the through hole of formula that circular bottom plate 1 and portable plate 2 gather makes the washability of fixed position between portable plate 2 and circular bottom plate 1 large, and be applicable to the testpieces of different volumes, applicability is strong, reusable, cost-saving.Further, the through hole that circular bottom plate 1 is gathered effectively alleviates the weight of circular base plate, make test faster light, raise the efficiency.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
