Problems solved by technology

[0004] In the prior art, when one or more samples are processed, they are generally pressed and positioned horizontally from the side, and the cutter cuts from the top; the up and down positioning of the samples is completely done by hand, and the left and right fixing and manufacturing processes In the process, the spline will shift due to the position of the force, resulting in an increase in the error of the notch, and it is difficult to ensure the parallelism of the spline notch, thus affecting the accuracy and precision of the test data

Abstract

The invention discloses a positioning clamp assembly for a notching machine. The positioning clamp assembly comprises a base, a horizontal compression assembly and a vertical compression assembly, wherein the vertical compression assembly comprises a compression assembly which can move vertically in a reciprocating way and a vertical driving device for driving the compression assembly to move vertically in the reciprocating way; and the compression assembly comprises a horizontally-arranged substrate and a vertical compression plate spherically articulated on the substrate. A simultaneous horizontal and vertical fixed clamping structure is adopted, and a self-adaptive pressure plate structure is adopted in the vertical direction, so that the positioning clamp assembly is suitable for processing a plurality of samples simultaneously and has uniform flatness; during notch processing, the samples can be fastened and positioned comprehensively and are fixed firmly, and each sample has a uniform standard; and the positioning clamp assembly has higher adaptability to sample height errors, i.e., a plurality of samples are positioned in a standard way, so that deviation in a processing process is avoided, the gap manufacturing parallelism of the samples is ensured, gap errors are reduced and even eliminated, and the accuracy and precision of test data are ensured.

Description

technical field [0001] The invention relates to a testing processing machine, in particular to a notch machine sample positioning structure. Background technique [0002] The notch machine is a device for notch sample preparation when testing the impact strength of materials; the existing notch machine is composed of a motor, a cutter, a sample table, a control panel and a cooling gas. [0003] When in use, fix the spline on the sample stage, start the instrument after setting the parameters on the control panel, and drive the cutter to rotate at the corresponding speed through the rotation of the motor at the set speed, and at the same time the sample stage translates at a certain speed to cut Sample, implements notch handling for splines. Spline notches of different heights can be obtained by adjusting the different heights of the notch, multiple samples can be processed simultaneously by extrusion positioning, and the interchange between standard splines of different siz...
