Tension testing machine applied to testing welding strength of glasses tobacco pipe

Abstract

The utility model discloses a tension testing machine applied to testing the welding strength of a glasses pipe, which is used for detecting the welding strength of the glasses pipe and improving the detection efficiency and the detection reliability. The tension testing machine comprises a first clamping mechanism, a second clamping mechanism, a detection device, a driving device and a base; the first clamping mechanism is used for fixing one end of the glasses tobacco pipe; the second clamping mechanism is used for fixing the other end of the glasses tobacco pipe; two guide sliding rods are arranged on the base, the driving device is arranged on the guide sliding rods in a sliding mode, limiting blocks are arranged at the top ends of the guide sliding rods, the driving device is connected with the first clamping mechanism, and the driving device is used for driving the first clamping mechanism to move in the direction away from the second clamping mechanism; and the detection device is connected with the first clamping mechanism, an S-shaped tension and pressure sensor is connected to the detection device, and the detection device is matched with the S-shaped tension and pressure sensor to be used for detecting the tension value of the glasses tobacco pipe.

Description

technical field [0001] The present application relates to the technical field of tensile testing, in particular to a tensile testing machine applied to testing the welding strength of spectacle pipes. Background technique [0002] Glasses are a tool for correcting vision or assisting vision, such as glasses for nearsightedness, glasses for farsightedness, sunglasses, etc. Based on the needs of vision correction or aesthetics, glasses have gradually become an indispensable necessity in people's daily life. Glasses are mainly composed of frames, temples, hinges, nose pads and lenses. For people who wear glasses, the frequency of use of glasses is very high. Therefore, people will consider whether the glasses are durable and have a certain degree of firmness. The mechanical properties have certain requirements. [0003] In the prior art, the testing of the mechanical properties of glasses generally focuses on testing the tensile properties of the glasses, and the testing is g...
