Abstract
The utility model discloses a fastener logic weighing auxiliary instrument, which comprises a base, indicator lamp assemblies and a controller, wherein the indicator lamp assemblies are arranged on the base, the number of the indicator lamp assemblies is the same as that of bolts of a fastener to be weighed, and the positions of the indicator lamp assemblies are in one-to-one correspondence; each indicating lamp assembly comprises an indicating lamp and a control switch. Each power supply output end of the controller, the control switch of the corresponding indicator light assembly and the indicator light form a power supply loop, and each signal detection end of the controller receives a detection signal of the on-off state of the corresponding power supply loop; the controller outputs the power supply signal to the power supply output end corresponding to the indicating lamp assembly in the current sequence according to a preset logic sequence, and switches the power supply signal to the power supply output end corresponding to the indicating lamp assembly in the next sequence after receiving the detection signal of the signal detection end corresponding to the indicating lamp assembly in the current sequence. And the detection signal of the signal detection end corresponding to the indicating lamp assembly in the last sequence is received. According to the scheme, guidance assistance can be provided for the complex and tedious fastening process, and the accuracy and reliability of the weighing work process are improved.
