Embodiment Construction

[0023] Embodiment one of the hardness tester tester of the present invention: as Figure 1-7 As shown, including a base 1, the base 1 is provided with a vertically arranged screw nut mechanism 2, wherein the screw is fixed in the vertical direction, and the nut threaded on the screw can move up and down when the screw rotates. The upper end of the leading screw nut mechanism 2 is provided with a rotating handle 20 for rotating the leading screw.

[0024] A durometer holder 3 is fixedly connected to the nut, and the durometer holder 3 can guide and move with the nut in the up and down direction. The hardness tester holder 3 includes an L-shaped plate with horizontal and vertical sides. The horizontal edge of the L-shaped plate, that is, the horizontal fixed plate 30, is detachably equipped with a spacer 33. The spacer 33 is provided with an upper support for the hardness tester 9 In this way, when testing different types or shapes of hardness testers, it is enough to separatel...

Abstract

The invention provides a hardness tester, comprising a base, the base is guided and moved upwardly and vertically and equipped with a hardness tester fixing seat, and the hardness tester fixing seat is provided with a lower end surface for upwardly supporting the lower shell of the hardness tester And a supporting part for the thimble of the lower casing of the hardness tester to protrude downward, and a pressing mechanism for vertically pressing the hardness tester on the supporting part is provided on the fixing seat of the hardness tester. When the hardness tester of the present invention is in use, the hardness tester is supported upward by the support part and the pressing mechanism presses the hardness tester downward to realize the fixation of the hardness tester, so that it will not be hard during the verification process of the hardness tester The problem of displacement in the longitudinal direction of the hardness tester occurs, which ensures the accuracy of the verification result.

Description

technical field [0001] The invention relates to a hardness tester. Background technique [0002] At present, most of the hardness tester verification devices commonly used in metrology departments are dynamometers. For example, the Chinese invention patent whose authorized announcement number is CN203643286U and whose authorized announcement date is 2014.6.11 discloses a Shore hardness tester. The gauge is fixedly installed on the movement mechanism of the hardness tester. The movement mechanism of the hardness tester can realize the vertical displacement of the hardness tester and act on the pressure sensor by the force of the thimble at the lower end of the hardness tester, and compare the detection value of the pressure sensor with the display value of the hardness tester. Calibrate the hardness tester. Among them, the hardness tester includes a display panel. The lower end of the display panel is provided with a lower case for protecting the thimble, and the middle par...
