Description
Technical field
The utility model relates to a kind of mechanics properties testing equipment, specifically refers to a kind of band locking fixture of device for testing tensile force.
Background technology
The bands such as existing plastic baling band are when needs carry out pulling force characteristic detection, general is all be fixed by the two ends of fixture by band, and is placed on measurer for pulling force, increases pulling force gradually to band, until band is pulled off, and the pulling force maximal value breaking moment is the maximum pull of band.Existing measurer for pulling force includes the jaw half of a pair mutual clamping engagement for the structure of the fixture of band locking, and it is fastening to carry out clamping by screw bolt and nut between this pair jaw half.This structure its to the clamping pressure fixedly placed one's entire reliance upon between a pair jaw half of band, due to the strip surface comparatively ring of light, clamping pressure then between jaw half must be very large, band could be locked, and the end of band is under so large clamping pressure, the easy compressive deformation in end of band or fracture, thus have impact on the accuracy of detection of band pulling force.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of reasonable in design, the band locking fixture of a kind of device for testing tensile force relying on band self self-tightening to fix.
For achieving the above object, the technical solution of the utility model includes clamping fixture seat, first half module and the second half module, the sidewall of this first half module is arranged the first band clamping surface and the first arc transiting surface, the sidewall of this second half module is arranged the second band clamping surface and the second arc transiting surface, described clamping fixture seat is provided with half mold mounting plate at the interval that is parallel to each other for a pair, the two ends, left and right of the first half module are fixedly installed between two-half die installing plate, described two and half mold mounting plates are respectively provided with the bar hole of about two parallel interval relative to the avris of the first half module, on the second described half module left and right end face each projection be provided with two respectively slippage to lead the guide finger be arranged in described bar hole, first band clamping surface of the first half module and the second band clamping surface of the second half module are arranged in opposite directions.
By this setting, when carrying out being fixedly clamped of band, the end of band is inserted between the first band clamping surface of the first half module and the second band clamping surface of the second half module, then by strip winding the first arc transiting surface and the second arc transiting surface on, under the effect of the coiling acting force of self of band, second half module moves and is close to the first half module in bar hole, makes to press from both sides tighter and tighter between the first half module and the second half module, thus band very stably can be fixed.
Further setting is the corrugated surface the first described band clamping surface and the second band clamping surface being provided with mutual concavo-convex adaptation.By this setting, improve the stability that band is fixing.
Further setting is that the first described half module and the second half module are semicircle column type, and the first arc transiting surface and the second arc transiting surface are provided with friction line.By this setting, improve the stability that band is fixing.
Further setting also includes clamping fixture seat mounting disc, and this clamping fixture seat mounting disc is fixedly installed pressure transducer, and this pressure transducer is fixedly connected with the top of clamping fixture seat.By this setting, pull sensing can be directly used in and detect.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
