The utility model content
The purpose of this utility model is to provide a kind of plastic baling band stretching mechanical property testing fixture, utilize water-drop-shaped self-tightening parts to form larger clamping surface of contact, and the characteristics of energy load self-locking, reduce the jaw damage of sample, avoid sample to skid in fixture, solve the problem of band sample in jaw place easy glide or damage.
The utility model is realized by following technical proposal: a kind of plastic baling band stretching mechanical property testing fixture, comprise connecting rod, main element, the self-tightening parts, auxiliary clamping device and baffle plate, the upper end of described main element arranges connecting rod for being connected with the testing machine chuck, water-drop-shaped self-tightening parts are offered in the front of main element, the self-tightening parts are that two bulk portions are spliced, and form clamping claw between main element and self-tightening parts and between two bulk portions, the back side of main element is equipped with baffle plate, the lower side of main element is provided with auxiliary clamping device.
Described main element is the cuboid structure.
The surface of the clamping claw formed between described main element and self-tightening parts is provided with serrated slot, for further strengthening, clamps effect.
Described baffle plate is the rectangle baffle plate, and fixes by screw and main element, for block the self-tightening parts from the back side.
Described auxiliary clamping device is comprised of inside and outside clamping plate and housing screw, and inner splint and external splint are fixed by screws on main element.
Mosaic face between described two bulk portions is S shape.
During test, sample is put into to the clamping claw between main element and self-tightening parts 3-1, then put into the clamping claw between self-tightening parts 3-1 and 3-2, and tighten baffle plate, the sample other end is also in like manner clamping, then connecting rod is clamped on the chuck of testing machine.At this moment, the two ends of sample are clamped by two parts of self-tightening parts, and along with the increase of pulling force, main element and self-tightening parts will be fully close, finally form self-tightening, and at the clamping claw place, well pincers are tight, avoided the sample slippage.Characteristic according to sample, also sample can be stepped up again through auxiliary clamping device, in clamping claw, by the face of opposed flattened, extruding clamps sample like this, can reduce preferably the jaw damage of sample, has overcome in the past terrace with edge shape or rectangle jaw and has clamped the damage that causes sample.
The utility model is usingd on main element water-drop-shaped clamping claw and water-drop-shaped self-tightening parts as the core texture of fixture, form the sample clamping claw, utilize the self-tightening effect of water-drop-shaped self-tightening parts, step up effect with the serrated slot on clamping claw in addition, thereby can firmly clamp the band sample.The auxiliary clamping device of setting up on main element and baffle plate, can further strengthen the degree of reliability that the band sample is clamped.By the connecting rod of main element upper end, can this fixture be clamped on the testing machine chuck easily, carry out the detection test of sample.
With the existing fixture used, compare, the utility model volume is little, lightweight, and simple in structure, convenient mounting and clamping, can the load self-tightening, can test and there is certain rigidity and flexible stripping tensile mechanical properties, overcome sample and clamped impaired or stressed phenomenon of skidding.Utilize water-drop-shaped self-tightening parts to form larger clamping surface of contact, and the characteristics of energy load self-locking, reduce the jaw damage of sample, avoid sample to skid in fixture, solve the problem of band sample in jaw place easy glide or damage.Be applicable to plastic strip, the steel such as plastic baling band and mould the Mechanics Performance Testing of composite strip sample and compound substance that can the flexing clamping, there is higher application and popularization value.
