Abstract
The invention discloses a vibration test clamp with the characteristic of free positioning. The vibration test clamp comprises a test body, three groups of telescoping rods and three groups of fixed pedestals. The whole clamp body is in an L shape; and telescopic rod mounting holes are respectively formed in the back of the connection part where the end surfaces of the two sides and the middle part are connected. The telescoping rods include rotation rods, top closing covers and bottom support segments, wherein the top closing covers and bottom support segments are in a screw joint with the two ends of the rotation rod; ball cavities are formed in the top closing covers and rotating balls are arranged in the ball cavities; and fixed terminals protruding outwardly are arranged on the rotating balls. The tops of the three groups of telescoping rods are respectively inserted into the three telescopic rod mounting holes and are locked; and the bottoms are fixedly connected with the fixed pedestals by the bottom support segments and then are fixed on a vibration bench surface by the fixed pedestals. Compared with the prior art, with the telescopic rods, a problem that the traditional clamp body can not be localized freely can be solved. Meanwhile, the telescopic rods with small sizes can be dismounted conveniently. On the one hand, the heavy manual labor is avoided; and on the other hand, the energy losses of the vibration bench are reduced.

Embodiment
Show for ease of technical characteristic of the present invention, below in conjunction with drawings and Examples, elaboration is done to the present invention.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Vibration table in the present invention and Fig. 1 with the use of, the component that this vibration test fixture can be opposite on shaking table is fixed, thus meets the vibration-testing requirement of component.As shown in Figure 1, vibration table is distributed with the screw that quantity is extremely many, the fixed installation demand of different component can be met.
With reference to Fig. 2 to Fig. 6, vibration test fixture of the present invention comprises chuck body 1, three groups of expansion links 2 and three groups of firm bankings 3.Firm banking, expansion link machine by aluminum material, and carry out shot blast.
Chuck body 1 entirety is L-type, and the back side of its both sides end face and junction, middle part is respectively equipped with expansion link mounting hole 4.Expansion link 2 comprises swing arm 5 and is bolted in top closing lid 6 and the bottom support section 7 at swing arm 5 two ends.By rotating swing arm 5, top closing lid 6 and bottom support section 7 indentation can be made or stretch out, thus realizing length adjustment.For the ease of operation, swing arm 5 can be provided with handle 15 outwardly for human users.Top closing lid 6 is provided with ball chamber, is provided with and turns ball 8 in ball chamber, turns ball 8 and is provided with fixed terminal 9 outwardly.The top of three groups of expansion links 2 is inserted respectively by fixed terminal 9 and is locked in three expansion link mounting holes 4, is fixed on vibration table after bottom is affixed by bottom support section 7 and firm banking 3 by firm banking 3 again.What turn ball 8 is arranged so that fixed terminal 9 can carry out the rotation of wide-angle by relative telescopic bar body, thus guarantees that expansion link 2 and chuck body 1 are formed and also can be inserted in expansion link mounting hole 4 in situation at any angle.In order to make the connection of fixed terminal 9 and expansion link mounting hole 4 more convenient, fixed terminal 9 adopts the mode be spirally connected to be fixed in expansion link mounting hole 4.
In order to make the connection between expansion link 2 and firm banking 3 more flexible, the end of bottom support section 7 is provided with bottom bolts fixed orifice 10, firm banking 3 comprises the matrix 11 for fixing with vibration table and is positioned at the clamping plate 12 that matrix 11 is oppositely arranged, the end of bottom support section 7 by through bottom bolts fixed orifice 10 and the bolt be fixed on clamping plate 12 and firm banking 3 be coupling.
In order to the request for utilization making fixture of the present invention can meet plate shell test specimen, the both sides end face of chuck body 1 and the back side of junction, middle part are respectively equipped with plate shell test specimen and laterally install seam 13 in the top of expansion link mounting hole 4, meanwhile, the upper side of chuck body 1 is provided with and extends to the horizontal fixed orifice 14 of plate shell test specimen that seam 13 laterally installed by plate shell test specimen.
Below using method of the present invention is described in detail.
After jig main body approximate location is determined, expansion link and firm banking thereof are placed vibration table, and adjustable telescopic rod length, search fixing threaded hole on vibration table nearby, firm banking and vibration table surface are bolted.By the fixed terminal of expansion link insert be locked in flexible mounting hole, adjustable telescopic rod swing arm subsequently, to its carry out fastening after swing arm is fixed.Should make overall planning with fixing in the location of three expansion links and firm banking thereof.So far single clamp main body is fixed complete, x, y and z of chuck body totally three direction displacements by restrained.The installation of multiple jig main body repeats above-mentioned steps; Until sample is firmly installed, thus install.
For plate shell class test specimen, after aforementioned jig main body position is determined, test specimen edge is placed main body biside plate shell test specimen and laterally install in seam, and fixed with screw in the horizontal fixed orifice of plate shell test specimen.
After sample installation, if find, overall or installation site, local needs adjustment, expansion link and firm banking can be unloaded, and adjusts expansion link length of rotary rod to control jig main body location simultaneously, thus realizes freely locating of jig main body.
For ensureing that jig main body is at the metastable state of vibration test process, the center line of three expansion links on the vibration table angle between two that projects should be made in expansion link floor installation process to be as far as possible 120
°, three expansion link center lines and vibration table surface should be made as far as possible to be 45
°angle; And length of telescopic bar is consistent as far as possible; The pretightning force of expansion link swing arm should keep identical as far as possible.
After vibration test completes, reference fixture installation steps backward carries out realization dismounting.Namely first unclamp expansion link swing arm gib screw, then unclamp swing arm, then unload expansion link base set bolt; For plate shell class test specimen, first clamper for disassembling body top gib screw, after take off test specimen, then dismantle expansion link base set bolt.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
