1. Application and applicable standards of microcomputer controlled self-locking nut performance testing machine
1. Purpose
This machine is mainly used for the locking performance test of hexagonal self-locking nuts, small hexagonal self-locking nuts, nylon hexagonal self-locking nuts, etc., to detect the maximum torque value of the first screw in and the minimum torque value of the last twist, the number of tests Set freely and automatically print data reports.The machine is automatically controlled by a microcomputer, the test speed is continuously adjustable, and there is a torque-torsion angle test curve. It is widely used in industries such as factories and mining enterprises, aerospace, scientific research institutes, automobile transportation, and quality supervision.
2. Applicable standards:
1) JB/T9370 "Technical Conditions of Torsion Testing Machine"
2) GB/T1337 "Hexagon self-locking nuts"
3) GB/T1339-88 "Small Hexagon Self-locking Nuts"
4) GB943 "Technical conditions for self-locking nuts"
5) HB8031 "Nylon Hexagon Self-locking Nut"
6) HB5643-87 "Self-locking Nut Test Requirements and Methods",
7) It can be customized according to other standards or special requirements provided by users .
