What are the limit protection and synchronous belt of electronic universal testing machine?

The electronic universal testing machine has many performance advantages. The limit rod and moving seat belong to the limit protection parts of the electronic universal testing machine. Electronic universal testing machine is an experimental instrument for researchers to test the mechanical properties of some materials. It has very advanced testing technology, which provides a lot of convenience for researchers' research work.

What are the limit protection and synchronous belt of electronic universal testing machine

Working principle of the machine: the computer system of the electronic universal testing machine controls the rotation of the servo motor through the controller and the speed regulation system. After deceleration by the deceleration system, the moving beam is driven to rise and fall through the precision lead screw pair to complete the tensile, compression, bending, shear and other mechanical property tests of the sample.

Machine characteristics: no pollution, low noise, high efficiency, with a very wide speed regulation range and beam moving distance. In addition, it is equipped with a wide variety of test accessories, which has a very broad application prospect in the mechanical property test of metal, non-metal, composite materials and products.

Usage and parameters: This machine can test rubber, plastic, leather, metal, nylon thread, fabric, paper, aviation, packaging, construction, vehicle and other materials, and can carry out tensile test, pressure test, peel test, tear test and shear bending test.

Limit protection function: on the left side of the main engine of the electronic universal testing machine, there is a sliding rod, which is the limit rod. The important function of limit rod is limit protection. In order to prevent the moving seat from exceeding the upper and lower limit positions and causing mechanical accidents, a safety protection mechanism is set. When the movable seat is at its upper / lower limit position, touch the contact of the upper / lower limit switch, so as to cut off the power supply of the machine and stop the testing machine.

Adjustment of synchronous belt: if the circular arc tooth synchronous belt for transmission is too loose or too tight, it will produce tooth climbing phenomenon, resulting in the fluctuation of test force and reducing the service life of synchronous belt. Therefore, the tension of synchronous belt should be appropriate When adjusting, loosen the screw on the motor carriage, move the carriage back and forth, and adjust the tightness of the synchronous belt until the finger pressure has obvious elasticity. When the adjustment is appropriate, tighten the four screws on the carriage.
