Abstract
The utility model discloses a kind of aximal deformation value clamping extensometer device, the utility model comprises Connection Block for connecting extensometer signals collecting end, for clamping the clamping part of sample, described Connection Block is connected by cantilever with clamping part, described clamping part comprise holding piece, with holding piece supporting rod connected vertically, described supporting rod is connected on cantilever by the through hole be vertically set on cantilever, is provided with the spring of compression between described supporting rod and cantilever.After the utility model adopts this structure, utilize the spring of the compression arranged between supporting rod and cantilever to realize the clamping of sample and to unclamp, simultaneously supporting rod can carry out 360 degree rotate carry out dress sample with, structure is simple, easy to operate, and the demand that spring carrys out satisfied different holding force in fact can be changed as required, good clamping effect, not easily slippage sample.
Description
Technical field
The utility model relates to a kind of clamping device, particularly a kind of aximal deformation value clamping extensometer device.
Background technology
Material tensile test is bearing the test method measuring material under axial tensile loads.And the deflection test of the large deformation such as rubber, plastics material, then need special large deformation extensometer, but the clamping device complex structure of current large deformation extensometer, complex operation during clamping sample, and clamping acting force is not strong, easily occurs the phenomenon of slippage sample.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and fill the aximal deformation value clamping extensometer device that sample is convenient, holding force is strong.
In order to solve the problems of the technologies described above, the utility model aximal deformation value clamping extensometer device comprises Connection Block for connecting extensometer signals collecting end, for clamping the clamping part of sample, described Connection Block is connected by cantilever with clamping part, it is characterized in that: described clamping part comprise holding piece, with holding piece supporting rod connected vertically, described supporting rod is connected on cantilever by the through hole be vertically set on cantilever, is provided with the spring of compression between described supporting rod and cantilever.
As further improvement, described cantilever is provided with grip slipper with holding piece correspondence position.
As further improvement, described spring is positioned at through hole.
As further improvement, described cantilever is made up of ABS material.This strength of materials is high, lightweight, and cost is low.
As further improvement, one end of described supporting rod is provided with the pressure cap being convenient to press, rotate.
The beneficial effects of the utility model: after the utility model adopts this structure, utilize the spring of the compression arranged between supporting rod and cantilever to realize the clamping of sample and to unclamp, supporting rod can carry out 360 degree of rotations and carry out dress sample and dismounting sample simultaneously, structure is simple, easy to operate, and the demand that spring carrys out satisfied different holding force can be changed as required, good clamping effect, not easily slippage sample.

Fig. 1 is semisectional view of the present utility model;
In figure: 1, Connection Block, 2, cantilever, 3, grip slipper, 4, holding piece, 5, supporting rod, 6, through hole, 7, groove, 8, spring, 9, protruding, 10, pressure cap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of aximal deformation value clamping extensometer device, comprise for connecting the Connection Block 1 of extensometer signals collecting end and the clamping part for clamping sample, described Connection Block 1 is connected by cantilever 2 with clamping part.As shown in Figure 1, clamping part comprises holding piece 4 and supporting rod 5, and the right-hand member of described cantilever 2 is vertically installed with through hole 6, and through hole 6 one end is provided with the groove 7 of annular, be set with spring 8 in groove 7, described supporting rod 5 outside surface is provided with the projection 9 identical with described groove 7 width.As shown in Figure 1, together with described supporting rod 5 to be vertically connected on holding piece 4 by the spring 8 in through hole 6 from the bottom up, now spring 8 is in compressive state under the effect of protruding 9.After the utility model adopts this structure, simple to operate when dress sample, only need to press supporting rod 5 during dress sample to make to produce gap between holding piece 4 and cantilever 2, sample is put into gap, holding piece 4 can under the elastic force of spring 8 self-return by sample holder on cantilever 2, simultaneously remove sample time only need rotate supporting rod 5 make holding piece 4 depart from sample.
More firm in order to by sample holder, as shown in Figure 1, cantilever 2 is provided with grip slipper 3 with holding piece 4 correspondence position.Grip slipper 3 matches by sample holder in centre with holding piece 4, and holding force is stronger; And clip position is more accurate, ensure that the accuracy of test figure.
As further improvement, as shown in Figure 1, spring 8 is positioned at through hole 6.
In order to weight reduction improves intensity simultaneously, cantilever 2 is made up of ABS material.
In order to more convenient to operate, as shown in Figure 1, on supporting rod 5, one end relative with holding piece 4 is provided with the pressure cap 10 being convenient to press, rotate.
The present embodiment is optimum embodiment of the present utility model, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
