Tension testing machine applied to testing welding strength of tooth nail of middle beam of glasses

Abstract

The utility model discloses a tension testing machine applied to testing the welding strength of a tooth nail of a middle beam of glasses, which is used for detecting the welding strength of the tooth nail of the middle beam of the glasses 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 comprises a first clamping main body and a first bolt, and the first bolt penetrates through the through hole and is used for fixing a middle beam tooth nail at one end of a glasses middle beam; the second clamping mechanism comprises a second clamping main body and a second bolt, and the second bolt penetrates through the through hole and is used for fixing a middle beam tooth nail at the other end of the glasses middle beam; the driving device is arranged on the guide sliding rod in a sliding mode, connected with the first clamping mechanism and used for driving the first clamping mechanism to move in the direction away from the second clamping mechanism; and the detection device is matched with the S-shaped tension and pressure sensor to detect the tension value of the middle beam tooth nail.

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 tooth nails in the middle beam of spectacles. 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 ...
