Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 1 and figure 2 , a spherical cover part hardness testing device includes a hardness testing machine 8, a tooling main body 1, a base 4 and a long compression rod 6, the long compression rod 6 is a telescopic rod, and the operator can adjust the position of the long compression rod 6 as required during the detection process. The length plays the role of adjusting the distance between the indenter and the spherical cover. The lower end of the tooling body 1 is provided with a chute 3, which is set on the central axis of the front and rear direction of the lower end of the tooling body 1, and runs through the entire bottom of the tooling body 1. , the main body 1 of the tooling is a stepped structure, the first step is a rectangular platform, the second step is a right-angled trapezoidal platform, the first step is a rec...

Abstract

The invention discloses a device and method for detecting the hardness of a spherical cover part. The device comprises a hardness testing machine and a long pressure rod, the test table of the hardness testing machine is fixedly provided with a tool main body, the long pressure rod is arranged between the hardness testing machine and a pressure head and is used for prolonging a distance between the testing machine pressure head and the hardness testing machine, the tool main body is provided with an oblique plane, the oblique plane is fixedly provided with a positioning boss, the positioning boss is in clearance fit with a hole in the bottom of the spherical cover part to be detected, and when the spherical cover part to be detected is fixed on the oblique plane, the relative plane part ofthe spherical cover part to be detected is positioned in the horizontal position. The device for detecting the hardness of the spherical cover part solves a problem that the surface Rockwell hardnessof the internal surface of the spherical cover is difficult to detect, and ensures the accuracy and the reliability of a detection result.

Description

technical field [0001] The invention relates to a surface Rockwell hardness detection device and method for the inner surface of a part, in particular to a spherical cover part hardness detection device and method. Background technique [0002] The technical specification of a certain type of engine spherical cover requires surface Rockwell hardness testing on the inner surface of the spherical cover, but currently there is no test device for testing the surface Rockwell hardness of the inner surface of the engine spherical cover in the field of physical and chemical mechanical testing. Because the inner surface of the spherical cover is an arc surface, the conventional hardness testing device cannot be applied to this situation. Moreover, in the process of performing Rockwell surface hardness testing on the inner surface of the spherical cover, it is difficult to place the parts and the position is not easy to fix. Contents of the invention [0003] In order to solve the...
