Abstract

The invention discloses a blade hardness detection auxiliary clamp. The clamp is fixed on a hardness machine rotary table through a supporting plate; a fixing block is fixed at the upper end of the supporting plate; a sliding groove is formed in the supporting plate; a sliding block is arranged in the sliding groove of the supporting plate; positioning grooves are formed in the fixing block and the sliding block; the center lines of the positioning grooves in the fixing block and the sliding block and the center line of the sliding groove in the supporting plate are located on the same straight line; the fixing block is fixed to the supporting plate according to the specification of a blade to be machined; the blade to be detected is placed in the positioning grooves of the fixing block and the sliding block by adjusting the position of the sliding block, and installation and positioning of the blade to be detected are achieved, so that hardness detection can be started; except that the distance between the fixing block and the sliding block of the clamp needs to be adjusted for a first piece, only precisely-forged blades need to be replaced for continuous measurement for multiple times, so that the operation content is simplified, the detection time is shortened, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of blade detection, and in particular relates to an auxiliary jig for blade hardness detection. Background technique [0002] Blade hardness testing is a form of material testing that is relatively easy to perform compared to other types of material verification equipment, and is usually completely or to a small extent non-destructive, and can often be performed directly on components without major alterations, currently mainly using The hardness testing device detects the hardness of the blade. The main body is the hardness testing instrument. The hardness testing instrument is divided into two types: desktop hardness testing instrument and portable hardness testing instrument. The desktop hardness testing instrument has the advantage of high precision. Mechanical or permanently assembled parts for easy portability. The desktop hardness tester adopts a unique and precise design in terms of machinery, optic...
