Problems solved by technology

Furthermore, since one of the positioning of the distance between the grippers and the attachment of the test piece to the gripper is visually confirmed by the operator, there is a problem that the setting varies depending on the operator.

Embodiment Construction

[0050] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a schematic diagram of the material testing machine of the present invention.

[0051] This material testing machine has: a table 16, a pair of pillars 19 installed upright on the ground, and a pair of screws 11 vertically installed on the table 16 inside each pillar 19 so as to be rotatable in a vertical direction. , a crosshead 13 movable along these screws 11 , and a loading mechanism 30 for moving the crosshead 13 and applying a test force to the test piece 10 .figure 1 3 shows a state in which the support 19 on the left side of the drawing is removed among the pair of support supports 19 .

[0052] The crosshead 13 is connected to a pair of screw rods 11 through nuts omitted in the figure. The lower end portion of each screw 11 is connected to the load mechanism 30 , and the power from the power source of the load mechanism 30 is transmitted to the pair of s...

Abstract

Provided is a material testing system provided with: an upper gripper 21 and a lower gripper 22 that grip a test piece 10; a video camera 18 that photographs the upper gripper 21 and the lower gripper 22 and the test piece 10; a first display part 25; a second display part 26; and a setting support section 61 that, in order to do test preparation where the test piece 10 is made to be gripped by the upper gripper 21 and the lower gripper 22, on the second display part 26, together with an image around the upper gripper 21 and the lower gripper 22, displays setting position indicators that support at least any one of positioning of the grippers, attachment of the test piece, and placement of gage marks to be marked on the test piece that is in a state of being gripped by the grippers.

Description

technical field [0001] The present invention relates to a material testing machine for performing a material test by applying a test force to a test piece. Background technique [0002] Such a material testing machine has, for example, a structure in which a pair of screws are rotatably supported on a table in synchronization with each other, and both ends of a crosshead are supported by these screws via nuts. Then, by rotating the pair of screws synchronously with each other by the rotation of the motor, the crosshead is moved along the pair of screws. Fixtures are respectively connected to the crosshead and the workbench. Furthermore, the test force is applied to the test piece by moving the crosshead in a state where both ends of the test piece are clamped by the pair of jigs. [0003] In such a material testing machine, a load cell or the like is used to detect a test force acting on a test piece. In addition, the displacement amount of the distance between the dots o...
