The left cylinder and the right cylinder are fixed at the two ends of the lower beam, the cylinder levers of the left cylinder and the right cylinder are fixed at the two ends of the upper beam, the upper beam is provided with an upper jaw, the lower beam is provided with a lower jaw, and the upper jaw and the lower jaw are arranged in an opposite way. The utility model has the advantages of simple and practical structure, convenient use, high positioning precision and accurate sample testing.
Description
Technical field
The utility model relates to testing machine parts technical field, especially a kind of universal hydraulic testing machine stretching crossbeam.
Background technology
Present employed universal hydraulic testing machine stretching header portion physical construction mainly comprises: entablature, and sill, column, the lead screw transmission part, and stretching attaches.It is the first that mainly there is following shortcoming in this mechanism, at the bottom of crossbeam jaw place intensity, the rigidity factor of assurance, uses jaw yielding for a long time, influences the testing machine precision, and texture ratio is heavy, and it is not very convenient using; The second, the lead screw transmission part is linked with the gap with leading screw, influences the horizontal accuracy of crossbeam location, has strengthened test error.
Summary of the invention
The purpose of this utility model provides a kind of universal hydraulic testing machine stretching crossbeam, and it has convenient the use, and the locating accuracy height is tested advantages such as accurate, can solve the shortcoming in the above-mentioned technology.
The technical scheme that realizes the utility model purpose is as follows:
Universal hydraulic testing machine stretching crossbeam, it mainly comprises entablature, sill, left oil cylinder, right oil cylinder, left side oil cylinder and right oil cylinder are fixed on the two ends of sill, the cylinder bar of left side oil cylinder and right oil cylinder is fixed on the two ends of entablature, entablature is provided with upper jaw, sill is provided with lower jaw, and upper jaw and lower jaw are oppositely arranged.
The cylinder bar of described left oil cylinder and right oil cylinder is fixed on the entablature by set nut.
Described left oil cylinder and right oil cylinder are synchronous fuel tank.
Adopted such scheme, when left oil cylinder and right oil cylinder are worked simultaneously, the cylinder bar is regained, entablature is along with the cylinder bar moves downward, when to correct position, the upper jaw of entablature and the lower jaw of sill are clamped sample, at the driving oil cylinder entablature is risen then, tensile sample, until sample fracture, test is finished.
Benefit of the present utility model is simple and practical, and is easy to use, the bearing accuracy height, and sample is accurate.
