Abstract
The utility model discloses a tester clamping body which comprises a support; the middle part of the support is provided with a groove; an oil cylinder is respectively arranged on both sides of the groove in the support; the piston rods of the two oil cylinders are dead against each other; and a jaw is respectively arranged on the piston rods of the two oil cylinders. According to the tester clamping body, the two jaws are respectively driven by the oil cylinder, so that the motion of the jaws is easy to control, the accuracy is high, sliding movement is uneasy, and the accuracy of the tester is high.
Description
Technical field
The utility model relates to a kind of grip of testing machine body.
Background technology
The grip of testing machine body is also claimed the jaw seat; It is the main mechanical composition part of Material Testing Machine; Clamping piston in jaw and the clamp body is connected, and the to-and-fro movement through clamping piston realizes the clamping of sample and unclamps, accomplishes the tension test of metal and nonmetallic materials thus.Main jaw form is a wedge shape in the hydraulic dynamometer at present, and this structure is easy to use, but jaw can produce opposite force to sample, the mechanical property of destructible sample itself, and test power accuracy is little.
Summary of the invention
The technical matters that the utility model will solve is: provide a kind of power of test accuracy high grip of testing machine body.
In order to solve the problems of the technologies described above, the utility model comprises bearing, and the middle part of bearing is provided with groove, and the both sides that are positioned at groove in the bearing respectively are provided with an oil cylinder, the piston rod of two oil cylinders over against, respectively be fixed with a jaw on the piston rod of two oil cylinders.
In order to make one-piece construction simple; The both sides that are positioned at groove on the said bearing respectively are provided with a secondary ladder hole, two secondary ladder hole axis point-blank, each secondary ladder hole respectively disposes a cylinder cap, a piston and a described piston rod; A secondary ladder hole, a cylinder cap, a piston and a described piston rod are formed a described oil cylinder; The aperture of two secondary ladder holes over against, cylinder cap is fixed on the outside of secondary ladder hole, piston is located in the macropore of secondary ladder hole; Piston rod is inserted in the aperture of secondary ladder hole; One end and the piston of piston rod fixed, the fixing described jaw of the other end, and cylinder cap is provided with the oil-in that communicates with the macropore of secondary ladder hole, and bearing is provided with the oil return opening that communicates away from an end of cylinder cap with the macropore of secondary ladder hole.
For the open and close movement accuracy that makes two jaws is higher, the bottom of described groove is provided with the guide plate in the piston motion direction guiding of two oil cylinders, and two jaws all place on the spigot surface of guide plate.
Damage jaw and piston rod for the oxide skin after preventing to test, described jaw is provided with protective cover.
The beneficial effect of the utility model: two jaws of the utility model are respectively by a hydraulic oil cylinder driving, and the motion of jaw is easy to control, and accuracy is high, and easy glide does not make that the accuracy of test power is high.
