(2) background technology
Testing machine can be to spring steel, stainless steel, foundry goods, copper pipe, non-ferrous metal, auto parts and components, rubber, plastics, expanded material, plastic cement, film, flexible packaging, tubing, yarn fabric, fiber, nano material, macromolecular material, compound substance, synthetic material, strap, paper, electric wire, optical fiber cable, securing band, safety belt, the leather belt, footwear, adhesive tape, alloy material and other nonmetallic materials and metal material stretch, compression, crooked, tear, peel off for 90 °, peel off for 180 °, shear, bounding force, withdrawal force, extend tests such as length growth rate.During test, sample article must be clamped on the testing machine chuck.At present, testing machine loading and unloading sample be hand-manipulated, and the weight of sample is generally greater than 10 kilograms, has not only been increased the labour, loses time but also operated not convenient by manually-operated, clamping, and security incident takes place easily.
(3) summary of the invention
The objective of the invention is to provide a kind of sample holder device of specimen test machine of suitable robotization, and reach the weight of clamping and the requirement that size can satisfy testing machine clamping sample article.
The objective of the invention is to be achieved through the following technical solutions.
A kind of sample clamping mechanism of testing machine is characterized in that:
The fixing cylinder in the center of grip slipper, the piston rod end that cylinder stretches out is provided with a centrepin;
The left and right sides of piston rod disposes two slide blocks triangular in shape respectively, and an angle of slide block is connected on the grip slipper with the pin-and-hole form by fixed pin; Slide block is offered slotted hole near an angle of piston rod, is placed on the centrepin; Another angle of slide block by removable pin with about respectively the configuration parallel calvus connect with the pin-and-hole form;
Parallel calvus is elongated, left and right two parallel calvus overlap each other and insert the other side, two waist shape slip slotted holes are offered in position, the left and right sides on parallel calvus, about two moving pins penetrate respectively in two slip slotted holes of two parallel calvus, the slotted hole direction of slip slotted hole is vertical with the piston rod moving direction of cylinder, and left and right two parallel calvus stretch out the jaw that gripping objects is used respectively perpendicular to the slotted hole direction of slip slotted hole;
About two parallel calvus in the activity of this mechanism, have two extreme positions, when moving pin is in end points of a parallel calvus slip slotted hole, be in another end points of the parallel calvus slip of another piece slotted hole just, vice versa.
Further, the forward surface of two jaws is the clamping face with asperities about described.
Further, the cylinder diameter of described cylinder is 60 to 65 millimeters.
Further, the length of two slip slotted holes is 20 to 30 millimeters about described.
Further, on the described slide block on the length direction of slotted hole and the slide block line of fixed pin holes and kingpin hole consistent, on the slide block slotted hole to the bee-line of fixed pin holes smaller or equal to the vertical range of centrepin to piston rod.
Adopt the technical program, when control cylinder work, piston stretches out, the centrepin that promotes the termination advances, be nested with two slide blocks about on the centrepin because the effect of fixed pin, can not advance, can only rotate around fixed pin, to open by the outside both sides of parallel calvus that removable pin connects, because the slotted hole that horizontally slips on the parallel calvus in the left and right sides is retrained by the moving pin in the hole, about two parallel calvus can only be abreast outwards both sides open, the jaw on the parallel calvus of interlock also opens to both sides, can prepare gripping objects.When object after between parallel calvus two jaws, cylinder oppositely shrinks piston rod, by above-mentioned relevant action transmission, two parallel calvus inwardly close up, and object is clamped.
Superiority of the present invention and beneficial effect be, adopts the technical program, needn't by manually-operated the clamping of test specimen object be transported again, only needs to start a cylinder and be convenient to work and can carry out the clamping sample article easily, correctly and accurately, transports then, in place.Operation is convenient, reliable in action, the accurate and difficult security incident that produces.
