Extensometer base and tensile testing machine with same

Abstract

The invention discloses an extensometer base and a tensile testing machine with the same. The extensometer base comprises a base and supporting plates connected to the two sides of the base through sliding rails. The base can slide back and forth between the supporting plates on the two sides through the sliding rails. A threaded rod is vertically arranged on the bottom face of the base in a penetrating mode, and the top of the threaded rod is connected with a full-automatic extensometer. The part, between the base and the full-automatic extensometer, of the threaded rod is sleeved with an adjusting knob, the adjusting knob can drive the threaded rod to ascend and descend in the vertical direction so as to drive the full-automatic extensometer connected to the upper portion of the threaded rod to ascend and descend, and the lower portions of the supporting plates are supported on a tensile testing machine. Operating rods used for driving the base to slide are arranged on the two sides of the bottom face of the base, locking clamping grooves are formed in the side faces of the supporting plates, and the operating rods can be clamped to the locking clamping grooves to limit the position of the full-automatic extensometer. Therefore, multi-directional adjustment of the position of the extensometer is realized, the influence of space limitation on the test precision is avoided, and the extensometer is convenient to move.

Description

technical field [0001] The invention relates to the field of performance detection of metal materials, in particular to an extensometer base and a tensile testing machine with the extensometer base. Background technique [0002] With the advancement of science and technology, the development of tensile testing machine technology is changing with each passing day, and the use of fully automatic extensometers on tensile testing machines is becoming more and more common. Compared with ordinary extensometers, fully automatic extensometers have the characteristics of high test accuracy, adjustable gauge length, and little influence from external interference factors, so they are more and more favored by test operators. [0003] However, in daily use, the extensometer base of the automatic extensometer still has the following disadvantages; the upper and lower sides of the extensometer are affected by its own working space. The test accuracy deteriorates; it is inconvenient to op...

[0003] However, in daily use, the extensometer base of the automatic extensometer still has the following disadvantages; the upper and lower sides of the extensometer are affected by its own working space. Poor test accuracy; inconvenient operation when the extensometer needs to be moved out of the working space of the tensile testing machine
