Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1 ~ Fig. 3, the utility model embodiment comprises clamp body 1 and horizontal stand 2.
The bottom of clamp body 1 is fixed on horizontal stand 2.Clamp body 1 and horizontal stand 2 one-body molded.Clamp body 1 is cuboid, and it is long is 68mm, and wide is 65mm, and height is 10mm, the size of suitable staff, conveniently takes and uses.Horizontal stand 2 is cuboid, and length is 100mm, and width is 80mm, is highly 5mm, and horizontal stand 2 machining precision must ensure, polishing need be carried out in surface.Fixing horizontal platform 2 is put in order to ensure that sample is placed in same level in the bottom of clamp body 1.
Clamp body 1 has successively a groove 3, No. two grooves 4 and No. three grooves 5, groove 3, No. two grooves 4 and No. three grooves 5 to be arranged side by side, a groove 3, No. two grooves 4 and No. three grooves 5 run through clamp body 1 in the height direction.A groove 3, No. two grooves 4 and No. three grooves 5 are the positions of placing impact specimen.A groove 3, No. two grooves 4 and No. three groove 5 identical length are together, highly also all identical.
Groove 3 one end open, conveniently puts into sample.A groove 31 is cuboid, and length is 55mm, is highly 10mm, and width is 10mm.
No. two groove 4 one end open, conveniently put into sample.No. two grooves 41 are cuboid, and length is 55mm, are highly 10mm, and width is 7.5mm.
No. three groove 5 one end open, conveniently put into sample.No. three grooves 51 are cuboid, and length is 55mm, are highly 10mm, and width is 5mm.
Be fixedly installed salient angle 6 in the middle of the sidewall of a groove 3, its end face flushes with the end face of clamp body 1, and bottom surface flushes with the bottom surface of clamp body 1.Salient angle 6 is towards No. two grooves 4.The xsect of salient angle 6 is isosceles triangle, and its base is fixed in the middle of the sidewall of a groove 3, and base is 2mm, and the height on base is 2mm, and the angle of drift angle is 45 degree.Salient angle 6 is to check Charpy key hole specimen break, is placed on by impact sample in a groove 3, can detects the length of sample, width, height and breach.
Groove 3 can detect that length is 55mm, width is 10mm, be highly the bulk sample of 10mm.Sample is put into a groove 3, if length all meets, then show that sample is qualified.
A groove 3 and No. two grooves 4 being combined, can detection width be the impact sample of 7.5mm.First can detect the length of sample, height and breach by a groove 3, then be detected the width of sample by No. two grooves 4; Also first can detect the length of sample, height and width by No. two grooves 4, a more logical groove 3 detects the breach of sample.
A groove 3 and No. three grooves 5 being combined, can detection width be the impact sample of 5mm.First can detect the length of sample, height and breach by a groove 3, then be detected the width of sample by No. three grooves 5; Also first can detect the length of sample, height and width by No. three grooves 5, a more logical groove 3 detects the breach of sample.
The utility model is inspection size, therefore higher to size tolerance requirements.
Clamp body 1 and horizontal stand 2 adopt 304 stainless steels to make, because the mould of straight carbon steel easily corrodes after contacting with water.
In addition, it should be noted that, the specific embodiment described in this instructions, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this instructions is only to the explanation of the utility model structure example.
