The invention discloses a standard block fixing frame used for calibrating the sample measuring mechanism of a tensile testing machine, that is, the fixing frame includes a support plate, a standard block clamp, fixing bolts and fastening bolts, and steps are respectively arranged at both ends of the support plate And a groove is provided in the center, a through hole is provided in the center of the groove of the support plate, a protrusion is provided at one end of the standard block clamp and a screw hole is provided in the center of the protrusion, and the protrusion at one end of the standard block clamp is located in the groove of the support plate. The fixing bolt penetrates the through hole of the support plate groove and is screwed into the screw hole of the protrusion at one end of the standard clamp to fix the standard clamp. The other end of the standard clamp is provided with a notch and a long groove is provided through the notch along the length direction of the standard clamp. The two sides of the standard block clamp are respectively provided with through holes and screw holes on both sides of the long groove, and the fastening bolts penetrate the through holes on one side of the long groove of the standard block clamp and are screwed on the screw holes on the other side of the long groove. The fixing frame can facilitate the calibration of the sample measuring mechanism, and the standard block used for calibration is conveniently fixed, improves the measurement accuracy of the sample measuring mechanism, and ensures the accuracy of the test result of the sample of the tensile testing machine.
Description
technical field [0001] The invention relates to a standard block fixing frame used for calibrating a sample measuring mechanism of a tensile testing machine. Background technique [0002] The tensile testing machine is mainly suitable for various tests such as tension, compression, bending, shearing, peeling, tearing, and two-point extension of metal and non-metallic materials. Its original cross-sectional dimensions, such as width, thickness, and circular specimen diameter, are critical to specimen results. In the fully automatic tensile testing machine, the sample measuring mechanism measures the cross-sectional size of the sample to provide subsequent test data calculations and obtain accurate test results. However, the calibration of the measurement accuracy of the sample measurement mechanism is related to the accuracy of the sample size measurement, which further determines the accuracy of the test results. The sample measurement mechanism moves and touches the sampl...
