Abstract

The invention discloses a durometer rack for improving accuracy of a hardness test result. The durometer rack comprises a base, an upright and an external inserting unit fixedly connected with the base, wherein a fixing hole provided with a clamping block is formed in the side wall of the base; a clamping component containing a first body and a clamping tool used for clamping a durometer stretches out of one side of the upright in a protruding manner; the first body and the clamping tool are arranged and matched in a sleeving manner; the external inserting unit comprises a base body, a fixing part and an inserting component; the fixing part comprises a column body and an arc-shaped fixing block used for fixing a columnar workpiece; the column body comprises a second body fixed on the base body and a lifting body rising and falling relative to the second body; the inserting component comprises an inserting rod, a push rod and a connecting rod respectively hinged to the inserting rod and the push rod; the inserting rod is inserted into the base; an accommodation groove is formed in the end part of the inserting rod; one end of an elastic projecting bar is fixedly connected with the accommodation groove, and the other end of the elastic projecting bar is propped against the clamping block; the push rod is vertical to the inserting rod, and can slide relative to the base body. The durometer rack is applicable to the hardness measurement of the columnar workpiece.

Description

technical field [0001] The invention relates to the field of hardness detection, in particular to a hardness tester stand for improving the accuracy of hardness test results. Background technique [0002] The Shore hardness test method was proposed by American Shore in 1907. It has the characteristics of rapid testing, shallow and small indentation, and simple operation. It is widely used in metallurgy, heavy machinery, and metal test pieces of large size and weight. hardness test. [0003] The Shore hardness tester can be measured by hand, but because the manual force control is not very stable, it is usually possible to use a stand to improve the measurement accuracy. The hardness tester stand usually mainly includes a base and a column for clamping the hardness tester. The base surface of the hardness tester stand is a plane. parts, more accurate results can be obtained. But when using it to test those columnar workpieces with a large aspect ratio, because it cannot be...
