Nut locking performance testing machine

Shandong Huayan nut locking performance testing machine is mainly used to detect the maximum torque (or moment) of the self-locking nut when it is screwed in for the first time, and the minimum torque when it is screwed out for the last time after 5 (or 15 or other) screwing-in and screwing-out cycles.It is automatically controlled by the computer, the motor is loaded, the maximum torque and the minimum torque are automatically detected, the number of screwing-in and screwing-out cycles can be set freely, and there are test curves, etc.It is widely used in factories and mines, aviation, aerospace, scientific research institutes, quality supervision and other departments that manufacture and use self-locking nuts to test the locking performance of self-locking nuts.

Applicable standards:

JB/T9370-2007 "Technical Conditions for Torsion Testing Machine"

GB1339 "Small hexagonal self-locking nut"

GB943 "Technical Conditions for Self-locking Nuts"

HB5643 "Self-locking Nut Test Requirements and Methods"

Product features:

1. Torsional torque and angle are displayed digitally;

2. The machine has a torque holding function;

3. The machine has overload protection function;

4. The machine has a torque-rotation angle curve diagram, in which the curve of each cycle can be selectively displayed. In order to facilitate observation, each curve can be selected in a different color as needed;

5. With result printing function;

6. The screwing in and out can be freely selected, the operation is simple, the detection speed is fast, and the clamping is convenient.
