Abstract

The utility model discloses a gripper for impact testing samples, which relates to an auxiliary device matched with an impact testing machine for use. The utility model solves the problems that no special sample placing device is provided for the impact test and the fatal safety hazard exists in the testing samples due to the placement operated by hand. The gripper for impact testing samples comprises a supporting table, a supporting rod is fixed on the table top of the supporting table, and the upper end of the supporting rod is provided with grippers capable of rotating around the supporting rod. The jaw of one gripper leaf of the grippers is provided with a V-shaped knife edge matched with the V-shaped slot on the testing samples. The gripper for impact testing samples of the utility model fills the blank that no special sample placing device is provided for the impact test; the utility model can effectively eliminate the risk factors existing in placing the samples by hand during the test and avoid the safety hazard. The utility model simplifies the process of placing the samples, namely that every time for manual aligning in the past is changed into one time for precise aligning; consequently the utility model shortens the operation time and enhances the test efficiency.

Description

The impulse test sample folds up device

Technical field

The utility model relates to and the matching used servicing unit of impact experiment machine, is specially the impulse test sample and folds up device.

Background technology

To semi-automatic impact testing machine, the placement of sample is entirely by manual operations in the test operation from the mechanical type impact testing machine, and when sample was placed, a hand-held sample was placed on punching groove, and another hand is then used the V-shaped groove on the aligner registration coupon.At this moment, ballistic pendulum is high to be hung, and the both hands of setting-out just in time are positioned at impact place of pendulum, careless slightly, or because mechanical fault very easily causes security incident.The pendulum of having uphang on the other hand also causes very big psychological pressure to operating personnel.

Summary of the invention

The utility model solves impulse test does not have special laying out apparatus, and sample is placed entirely by manual operations, has the problem of very big potential safety hazard, provides a kind of impulse test sample to fold up device.

The utility model is to adopt following technical scheme to realize: the impulse test sample folds up device, comprises brace table, is fixed with pole on the table top of brace table, and the upper end of pole is provided with can be around the clamp of pole rotation; Have the V-arrangement edge of a knife that cooperates with V-shaped groove on the sample on the jaw of one of clamp pincers leaf.During use, place the punching groove outside of impact testing machine with folding up device, clamp clamps sample, and the V-arrangement edge of a knife on the grip finger is matched with V-shaped groove on the sample.Adjustment folds up the mutual alignment of device and impact testing machine, maybe will fold up the device brace table and determine the fixed position of pole on the brace table table top, make the punching groove of just in time sample being put into exactly impact testing machine after the clamp rotation near the punching groove of the impact testing machine outside.After adjust the fixed position that folds up the position of device or pole, can guarantee that sample can both put into punching groove at every turn exactly.

The upper end of pole directly is articulated in the pin joint place of clamp two pincers leaves.Like this, can realize the folding of two pincers leaves of clamp, can realize that again clamp rotates around pole.Realize the rotation of clamp around pole with this structure, structure is simple relatively.

The connecting link of the hinged downward extension in pin joint place of clamp two pincers leaves, the pole upper end is provided with spill spin block, and connecting link connects with spill spin block.Like this, spill spin block can rotate on pole.Realize the rotation of clamp around pole with this structure, rotation, the folding of clamp are more flexible.

Impulse test sample described in the utility model folds up device, has filled up the blank that impulse test does not have special laying out apparatus, can effectively eliminate the hazards that manual lofting exists in the test, avoids potential safety hazard.Simplified the setting-out program, made setting-out, be reduced to once and aim at by original craft time time " aligning ", inferior accurate, shortened the running time, improved test efficiency.

Embodiment

The impulse test sample folds up device, comprises brace table 1, is fixed with pole 7 on the table top of brace table, and the upper end of pole is provided with can be around the clamp 3 of pole rotation; Have the V-arrangement edge of a knife 8 that cooperates with V-shaped groove on the sample on the jaw of one of clamp pincers leaf.

The upper end of pole 7 directly is articulated in the pin joint place of clamp two pincers leaves.

The connecting link 9 of the hinged downward extension in pin joint place of clamp two pincers leaves, the pole upper end is provided with spill spin block 2, and connecting link 9 connects with spill spin block 2.

Be fixed with clamping plate 11 on the jaw of another pincers leaf of clamp, to increase the stability of sample holder.

Be provided with pole fine position mechanism on the brace table table top, micro-adjusting mechanism is made of the voussoir 10 in slide block 5 that has dovetail groove on it and the slide block dovetail groove; Slider bottom be provided with bolt and by bolt on vertical adjustment hole 6 of being opened on the brace table table top, pole 7 is fixed on the voussoir 10.The lengthwise position of slide block 5 mobile scalable pole in vertical adjustment hole 6, the lateral attitude of voussoir mobile scalable pole in the dovetail groove of slide block.Pole fine position mechanism can accurately finely tune the position of pole on the brace table table top, thereby further guarantees the degree of accuracy of sample placement location, the adjustment of the pole position of also being more convenient for (avoiding moving too much folding up device integral body).Also make applicator more be common to the sample of different size.

On the brace table table top, also be fixed with material platform 4, so that depositing with clamp of sample clamps sample.
