Abstract
The utility model is related to field of machining, disclose a kind of Z-direction tensile sample clamp, the thin endoporus being adapted to outer diameter in the middle part of tensile sample is arranged in the clamp bare terminal end；The length of the thin endoporus is 1/4 1/3 of total length in the middle part of tensile sample；The thick endoporus being adapted to tensile sample bare terminal end outer diameter is arranged in thin endoporus one end in the clamp, and the length of the thick endoporus is more than tensile sample bare terminal end length, and the clamp is put together by two half clamps.The utility model solves Z-direction tensile sample and is not easy to be clamped, and the axis of external thread of two bare terminal end of sample processing is misaligned, the problem of sample bias, and the utility model is simple in structure, adaptable.
Description
Technical field
The utility model is specifically related to field of machining, relates more specifically to a kind of Z-direction tensile sample clamp.
Background technology
As external inspection field is more and more wider, the tensile sample of the machine-shaping of inspection is smaller and smaller, even reaches sometimes
To entire tensile sample ＜ 50mm, sample holder span access location length cannot be clamped in Material Testing Machine and carry out less than 15mm at all
Experiment.
It is by tensile sample retaining part both ends center jewel hole so as to solid for the traditional processing method of these tensile samples
After determining tensile sample, uses lathe in sample holder position vehicle external threads again, reprocess the inner thread sleeve to match therewith
It is used cooperatively to lengthen retaining part length.But in machined molding Z-direction tensile sample bare terminal end center jewel hole, it is difficult to ensure that
For the eye of brill at bare terminal end center, the axis of external thread that this results in two bare terminal end of sample to process is misaligned, and sample is eccentric, specimen holder
Axis in Material Testing Machine is not overlapped with testing machine axial force, causes inspection data less than normal, inaccurate.
Utility model content
It is not easy to be clamped to solve Z-direction tensile sample in the prior art, the axis of external thread of two bare terminal end of sample processing is not
It overlaps, the problem of sample bias, the utility model provides a kind of Z-direction tensile sample clamp.
The utility model adopts the following technical solution：A kind of Z-direction tensile sample clamp, in the clamp bare terminal end setting with
The thin endoporus of outer diameter adaptation in the middle part of tensile sample；The length of the thin endoporus is the 1/4-1/3 of total length in the middle part of tensile sample；Institute
It states thin endoporus one end in clamp and the thick endoporus being adapted to tensile sample bare terminal end outer diameter is set, the length of the thick endoporus, which is more than, draws
Sample holder end length is stretched, the clamp is put together by two half clamps.
The utility model is by being arranged groove compatible with tested tensile sample outer diameter respectively inside clamp, to tested
Sample carries out after centainly wrapping up, and is well fixed on testing machine convenient for Z-direction tensile sample and carries out tensile testing, in practical operation
It is convenient and efficient in journey, there is very strong practicability.
Description of the drawings
Fig. 1 is the utility model and schematic diagram；
Symbol description
1, clamp, 2, in the middle part of tensile sample, 3, thin endoporus, 4, thick endoporus, 5, half clamp, 6, tensile sample bare terminal end.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
With reference to attached drawing, the utility model provides a kind of Z-direction tensile sample clamp, is arranged and stretches in the clamp bare terminal end
The thin endoporus of outer diameter adaptation in the middle part of sample；The length of the thin endoporus is the 1/4-1/3 of total length in the middle part of tensile sample；The folder
The thick endoporus being adapted to tensile sample bare terminal end outer diameter is arranged in thin endoporus one end in pipe, and the length of the thick endoporus, which is more than to stretch, to be tried
Sample bare terminal end length, the clamp are put together by two half clamps.The production method of the clamp is as follows：
1, the steel plate of 1 suitable length, thickness is taken（Length determines that thickness is according to experiment according to testing machine jaw leaf length
Distance between machine jaw piece）The pole for needing size is made.
2, thin endoporus will be drilled out among pole, thin diameter of bore is adapted with outer diameter in the middle part of tensile sample, the thin endoporus
Length be tensile sample in the middle part of total length 1/4-1/3 when clamping effect most
3, thick endoporus will be drilled out among pole rest part, thick diameter of bore is adapted to tensile sample bare terminal end outer diameter, institute
The length for stating thick endoporus is more than tensile sample bare terminal end length
4, pole is cutd open into two halves from centre one, obtains two half clamps.
When in use, 4 clamps clamp tensile sample, and Z-direction tensile sample is fixed, and will not be shaken in draw direction
It is dynamic, achieve the purpose that carry out tension test, when measuring, clamp end is fixed on testing machine and carries out tensile testing, this reality
With convenient and efficient in novel actual mechanical process, there is very strong practicability, it is too short to solve tested sample, two bare terminal end of sample
The axis of external thread of processing is misaligned, the problem of sample bias.
