Abstract
The utility model belongs to a physical and chemical test fixture and relates to a microhardness test clamping device. The clamping device comprises a clamp body, a positioning pin, a clamping nut andan inclined positioning block, wherein the clamp body is L-shaped; a positioning pin is installed on the vertical plane of the clamp body; one end of the positioning pin is provided with screws; theclamping nut is screwed with the positioning pin and the inclined positioning block is mounted on a base of the clamp body. The utility model adopts the structure which mounts the inclined positioningblock on the base, arranges local area of the pre-test surface on the level position, thus solving the problem of not easy to position for the part curved surface and meeting the requirement of the hardness test by adjusting the inclined positioning block when parts have errors and a few wearing. The utility model flexibly and reasonably positions based on the part shape, performs the microhardness test after slightly polishing the part surface and saves the part cutting expenditure and the sample preparing expenditure under the premise of meeting the requirement of the microhardness test.
Description
Technical field
The utility model belongs to the physical and chemical testing anchor clamps, relates to a kind of micro-hardness testing clamping device.
Background technology
At present, when hardness test is carried out on the arc part surface, because of the part shape complexity, the test mode of Cai Yonging is that pretest with part partly cuts down a part and is placed on the microhardness testers objective table and tests all the time, because test specimen is complex-shaped, do not cut to be placed in and determine the test plane on the microhardness testers objective table, as: the curved surfaces of parts such as minicar engine valve rocker.
Summary of the invention
The purpose of this utility model provides a kind of micro-hardness testing clamping device that just can carry out piece surface hardness without cutting parts.Technical solution of the present utility model is, clamping device comprises clamp body, register pin, grip nut and oblique locating piece, clamp body is " L " shape, installing and locating pin on the clamp body vertical plane, and an end of register pin is provided with screw thread, grip nut is threaded with register pin, and tiltedly locating piece is installed on the base of clamp body.Advantage that the utlity model has and beneficial effect, the utility model adopts the structure that oblique locating piece is installed on base, pretest surface local zone is horizontal, overcome the deficiency of the difficult location of part curved surface, when part has the sum of errors small amount of wear, can satisfy the hardness test requirement by oblique locating piece adjustment.The utility model according to the part profile flexibly, location reasonably, piece surface can carry out micro-hardness testing after through slight polishing.Guaranteeing to satisfy under the prerequisite of micro-hardness testing saving part cutting expense and specimen preparation expense.
