Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] refer to figure 1 , the welding main body of the present invention is a contact knife 230, and the upper surface of the front section of the contact knife 230 is a trapezoidal upper boss 233; Boss 235 and rear groove 234, rear groove 234 and upper boss 233 positions are opposite up and down, the rear section of contact knife 230 is bent downward, and in the rear part of contact knife 230, there is support hole 231 transversely. The upper boss 233 is a trapezoidal boss with a bottom edge of the lower step of the assembly contact 232 with a depth of less than 1.5mm, and square grooves for soldering pieces and flux (the addition of square grooves to the contact blade 230 is an innovation).

[0040] The purpose of the present invention is to adopt automatic welding and automatic assembly, automatically drop soldering flux from top to bott...

Abstract

The invention discloses a full-automatic welding system for a contact knife of a frame circuit breaker. The system is structured such that a rotary disc is arranged on a table-board, the rotary disc is in control connection to a multi-station slicer, eight opened slots are uniformly formed in the upper surface of the rotary disc along the circumference, and a locking clamp is fixedly mounted in each opened slot; a contact knife loading mechanism, a flux loading mechanism, a contact loading mechanism, a welding mechanism and a product discharging mechanism are arranged on the table-board aroundthe rotary disc; the eight locking clamps correspond to eight stations; in an initial state, the first station corresponds to the contact knife loading mechanism, the second station corresponds to the flux loading mechanism, the third station corresponds to two detection sensors, the fourth station corresponds to the contact loading mechanism, the fifth station corresponds to an inductor I, the sixth station corresponds to the welding mechanism, the seventh station corresponds to an inductor II, and the eighth station corresponds to the product discharging mechanism. The device improves the efficiency and the primary penetration rate, and the service life of an electrode is prolonged greatly.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a fully automatic welding system for contact blades of a frame circuit breaker. Background technique [0002] The arc-shaped contact is widely used in the conductive system of low-voltage electrical appliances due to its large breaking capacity and large current carrying capacity. The large-scale contact knife system is a thick arc-shaped contact with a thick middle and two sides. It adopts the existing welding vertical pressure high current and high pressure. In the multiple welding method, the current carried by the electrode cannot be distributed to the relatively thick middle contact surface of the arc-shaped contact. Before the product is penetrated, the electrode has softened, deformed and cracked, and cannot be formed. [0003] The welding process of small-sized contact blades is fixed by simple fixtures, and then manually add solder pieces, flux, contacts, manuall...
