Description

A five-degree-of-freedom socket welding support base

technical field

The invention belongs to the technical field of electrical assembly of a solid rocket motor ignition system, in particular to a five-degree-of-freedom socket welding support base.

Background technique

DZ series safety mechanism socket electrical assembly refers to the welding of the internal wire of the mechanism and the socket contact. In the traditional socket and wire soldering process, since the socket lacks a reliable support position, the following steps are required during soldering:

1) Hold the socket with the middle finger, ring finger and little finger of the left hand. It is required that the socket cannot be loosened to prevent the socket and the wire from being pulled down. Secondly, the socket must be within an appropriate distance;

2) Due to the large number of welding wires, it is necessary to take out the wires one by one with the right hand;

3) Hold the tweezers with the index finger and thumb of the left hand, use the tweezers to hold the wire pulled out by the right hand, and send the end of the wire to the welding position;

4) Apply the flux with the right hand and hold the soldering iron for soldering.

This welding method has complicated process and strict quality requirements, which puts forward higher requirements on the welding skill level of operators. In addition, the welding process mainly has the following difficulties:

1) During the welding process, the left hand must always maintain a posture, each of the five fingers has its own purpose, and the posture is difficult, which requires higher requirements for the operator and increases the burden on the left hand;

2) There are many wires that need to be welded. The DZ series safety mechanism generally has 19 wires, and the right hand picks out 19 wires in turn with one hand, which is not easy to operate;

3) The quality of wire welding is very high, and the welding time is long. Due to the complicated posture of the left hand, it is easy to cause fatigue and soreness of the left hand over time.

To sum up, in the current socket welding process, the operator's technique is required to be high, and the welding process is difficult, which causes the operator's hands to be fatigued.
