Problems solved by technology

[0003] The clamping action, release action, and clamp reset of the traditional semi-automatic punctuation extensometer are all manually operated by the staff. In practical applications, the amount of sample testing is large, and it is cumbersome to load and unload the sample back and forth and adjust the equipment. operation reduces work efficiency

Abstract

A semi-automatic punctuation extensometer includes: a frame, a clip device, a motor, a transmission device, an extension sensing device, a control device, and a return device. The frame is provided with a guide rod, and the guide rod is fixed between the extension induction device and the transmission device. The clip device is worn on the guide rod and can slide along the guide rod. The transmission is provided with an eccentric rod connected to the motor. The motor is fixed to the transmission. The extension sensing device is connected with the clip device. The control device is electrically connected with the motor and the extension induction device, and is also electrically connected with the tensile testing machine to obtain working data of the tensile testing machine. The above-mentioned semi-automatic punctuation extensometer realizes manual starting and automatic reset of the equipment, achieves the purpose of semi-automation, and improves the working efficiency of the equipment.

Description

technical field [0001] The invention relates to a rubber stretch detection device, in particular to a semi-automatic punctuation extensometer. Background technique [0002] Rubber has the property of being stretchable. In order to measure the tensile force that rubber can withstand and the elongation when it is stretched and broken, it is necessary to cooperate with a tensile testing machine and an extensometer. The sample is cut into a dumbbell shape, and the upper and lower clamps of the tensile machine are respectively clamped at both ends of the sample, wherein the lower clamp remains stationary, and the upper clamp is driven by the motor to stretch the sample upward until the test The sample was broken, and the tensile value of the sample was recorded at the same time. The extensometer is equipped with two clamps, which are respectively clamped in the middle of the sample, and the clamping positions of the two clamps form a certain clamping distance. As the sample is s...
