Description

Technical Field

[0001] The utility model belongs to the technical field of Shore hardness testers, in particular to a Shore hardness tester with a three-point support frame. Background Art

[0002] The patent document with application number 202410206418.1 discloses an improved Shore hardness tester, comprising: a double-layer frame, the double-layer frame comprises an upper platform and a lower platform, an n-shaped frame and a height measuring assembly are arranged above the upper platform, which correspond to four working surfaces: a test bench mounting surface, a punch lifting assembly mounting surface, a punch guide assembly mounting surface and a height measuring assembly mounting surface.

[0003] It is very important whether each working surface of the Shore hardness tester is in a horizontal state. Whether the mounting surface of the height measurement component is horizontal is related to the accuracy of the height measurement. The level of the mounting surface of the punch guide component and the punch lifting component will affect whether the punch falls freely. The level of the test table mounting surface directly affects the rebound height, thereby affecting the final Shore hardness value. However, each mounting surface in the patent document is provided with four supporting points, and it is difficult to adjust the horizontal state of the platform with four supporting points. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a Shore hardness tester with a three-point support frame, which can quickly and accurately adjust the horizontal state of each working surface.

[0005] The utility model is achieved in this way:

[0006] A Shore hardness tester with a three-point support frame comprises: a height measuring component installed on the frame, a punch grabbing and releasing component, a punch guiding component, a punch lifting component, a hardness block, and a test bench;

[0007] The frame includes four mounting surfaces from top to bottom: a height measurement component mounting surface, a punch guide component mounting surface, a test table mounting surface, and a punch lifting component mounting surface;

[0008] Each of the installation surfaces comprises: a working surface platform and three supporting members below the working surface platform; the three supporting members of the installation surface located above are arranged on the working surface platform of the installation surface located below.

[0009] Furthermore, the working surface platforms of the test bench mounting surface and the punch lifting assembly mounting surface are both triangular platforms; the three supporting members of the punch lifting assembly mounting surface are arranged on the working platform of the Shore hardness tester; and the three supporting members of the test bench mounting surface are arranged on the working surface platform of the punch lifting assembly mounting surface.

[0010] Furthermore, the working surface platforms of the height measuring component mounting surface and the punch guide component mounting surface each include a circular platform located in the center and three extension members equidistantly distributed on the periphery of the circular platform, and a support member is arranged under each extension member; the three support members of the punch guide component mounting surface are arranged on the working surface platform of the test bench mounting surface; and the three support members of the height measuring component mounting surface are respectively arranged on the three extension members of the punch guide component mounting surface.

[0011] The utility model has the advantages that each installation surface of the frame is supported by three points, the three points can determine a plane, and the level of each working surface can be adjusted quickly and accurately. BRIEF DESCRIPTION OF THE DRAWINGS
