Technical Field

[0002] It is used for testing the mechanical properties of metals, non-metals, and composite materials. It can also be used as a testing device for technical training, software testing, and product function demonstration. The servo slide rail is fixed to the bidirectional testing frame by screws through upper and lower brackets. The slide rail is equipped with force sensors and displacement sensors. At one end of the force sensor, there is a mechanical clamp for holding the sample during tensile testing and a pressure plate for compressive testing.

Currently, the structure of a servo motor-driven bidirectional tensile and compressive testing device is basically a double-screw gantry type. The double-screw gantry type structure uses an electric motor to drive two screws to move the upper crossbeam, thereby applying axial force to the specimen between the upper and lower crossbeams.

However, the mechanical structure of a servo motor driven bidirectional tensile and compressive testing device is relatively complex, bulky, and expensive.

The inner diameter of the protective cover 105 is adapted to the outer diameter of the bidirectional test frame 1.
[0027] Working principle: Rotating the adjusting disc 92 causes the worm gear 90 to rotate, which in turn drives the turbine 93 to rotate, which in turn drives the threaded rod 91 to rotate, which in turn drives the sliding frame 95 to move, which in turn drives the support 94 to move, which in turn drives the pulley 97 to contact the ground, thus supporting and lifting the bidirectional testing frame 1, making the equipment easy to carry and move. The vibration generated during the movement of the pulley 97 is transmitted to the support 94, which compresses the spring damper 96 to buffer and reduce vibration, thereby reducing the risk of loosening and damage to the components on the bidirectional testing frame 1. After the movement is completed, the L-shaped clamping plate 103 is moved to compress the spring 104, and at the same time, the L-shaped clamping plate 103 moves and separates from the positioning groove 101, which then separates the protective cover 105 from the top of the bidirectional testing frame 1, allowing the internal testing device components to be unfolded or reversed for protection and dust prevention.
