Description

Automatic locking equipment of circuit breaker connection terminal screw
Technical Field
The invention relates to the technical field of automation equipment, in particular to automatic locking equipment for a circuit breaker wire holder screw.
Background
With the development of intelligent manufacturing, the customization requirements of customers and the labor cost are improved, the production efficiency is improved, and the introduction of automation equipment into a production line of intelligent manufacturing is a development trend. The existing locking screw technology cannot meet the requirements of customers for specificity, diversification and customization, even if the types of wire holders at the inlet and outlet ends of the circuit breaker for the same type of aviation airport are various, the existing equipment cannot be automatically produced, for example, in order to install different inlet and outlet electric cables, the installation gap between the wire holder of the circuit breaker and the base of the circuit breaker cannot be unified, the design gap has to be larger than more than 3mm, so that the screw locking offset between the wire holder and the plastic shell base is large, the screw locking screws of the wire holder have to be manually assembled and manually rotated to fix the cable, and the manual locking screw technology has low efficiency and high labor intensity and is difficult to adapt to the production requirements; the torque force cannot be correctly controlled by manually locking the screws on the auxiliary wire holders, so that the screws cannot be loosened when a user needs to loosen the screws during wiring; the complaints of users are many.
The 2 poles, the 3 poles and the 4 poles of the common circuit breaker for the airport electric power system are configured according to a certain proportion system, the length and the width of the common circuit breaker have large size difference (the length of the 2 poles is 25mm different from that of the 3 poles, and the width of the common circuit breaker is one pole groove width, and the length of the 3 poles is 30mm different from that of the 4 poles, and the width of the common circuit breaker is one pole groove width).
The existing screw locking mechanism corresponds to a fixed variety of screws and a fixed distance locking pair, any one of the screw and screw distances cannot be locked after being changed, the distance cannot be adjusted, and the screw locking mechanism which is automatically adjustable and applicable to screws with different specifications and adjustable different gaps is not provided, for example, a screw at an inlet end is M7x20, a screw at an outlet end is M6x18, the screw distance is 30mm and 25mm, and screws at an upper cover M5x50 are 90mm and 85mm, so that the screw locking mechanism cannot be assembled and locked on the same equipment and can only be locked on six different pieces of equipment;
the existing automatic special machine cannot be compatible with 2-pole, 3-pole and 4-pole products, and the length-width ratio of a breaker product is greater than 2: 1, 2 poles, 3 poles and 4 poles of the circuit breaker are positioned in a conveying track, material clamping faults often occur in the length direction, and the conventional conveying belt cannot convey normally; the existing conveyer belt can not finish the operation requiring the positioning precision and quality due to the position deviation and the positioning deviation caused by the shake generated by the movement, the abrasion to the workpiece, the process switching, the inertia overshoot generated by the movement and the like.
Except that there is not compatible 2 utmost point, 3 utmost point, 4 utmost point location and conveying mechanism, prior art does not have automatic identification, applicable 2 utmost point, 3 utmost point, 4 utmost point bases, and the mechanism of different interval and different specification screws, and current electric wholesale is with fixed solid fixed ring of fixed electric wholesale easily to produce wearing and tearing in addition, makes the electric wholesale take the wholesale head slope, easily produces the locking and pays badly, leads to the leading cause that can't automatic production.
For the safety of wiring, 2-pole, 3-pole and 4-pole wiring screws of the common circuit breaker for the airport adopt combined screws of elastic pads and flat pads which are not less than M6, particularly for the safety of wiring, the inclination of the elastic pads and the flat pads is far greater than the conventional inclination, and the locking and anti-loosening force of locking screws is increased; however, the combination screw automatic feeding, sequencing and locking of the deep-hole screw are greatly unstable, and the overlapping and material clamping of the adjacent screw elastic pad and the flat pad often occur in the processes of feeding, feeding and locking; the machine lock attaches the screw and holds back to death, once locks and attaches the success rate low.
