Embodiment Construction

[0021] A sample automatic centering size measurement device, including a base plate 1, on which a sample clamping displacement mechanism, a sample centering displacement mechanism, a sample centering mechanism and a sample measuring mechanism are fixed, wherein:

[0022] The sample clamping and displacement mechanism includes an X-axis guide rail 2 arranged transversely on the base plate 1. There is a moving connecting plate 3 on the guiding rail 2. The moving connecting plate 3 is pushed by a ball screw 4 connected to a servo motor 5. Horizontal sample clamping air claws 6 are installed on both sides of the connecting plate 3, and one side of the air claws is connected with a horizontal rotating cylinder 18;

[0023] The sample centering displacement mechanism includes two left and right Y-axis guide rail bridges 7 fixed on the base plate 1 perpendicular to the X-axis guide rail 2 and set across the X-axis guide rail 2. The two guide rail bridges 7 are equal in height and high...

Description

technical field [0001] The invention relates to an automatic size measuring device, in particular to a device for measuring the size after automatic centering of a sample to be tested. Background technique [0002] In the tensile test of metal parts, before and after the tensile test, the size of the sample is generally still measured manually (for example: the tool is a vernier caliper), and the inspector will give the sample due to different techniques and visual errors. The size measurement results bring large errors. For example, in the mechanical tensile test of steel samples, in order to obtain a series of data such as the ductility of steel samples, it is generally necessary to test the relevant dimensions of the sample at multiple points before and during the test, as shown in the attached figure 1 For a standard steel sample, it is necessary to test the width and height of multiple points on the sample. The current manual test not only produces an error in the meas...
