In order to achieve the above purpose, the utility model adopts the technical scheme that: the transfer mechanism of the circuit breaker welding equipment comprises a conveying rail and mechanical arms arranged at two ends of the conveying rail, wherein a conveying belt is arranged on the conveying rail, a plurality of fixing seats are arranged on the conveying belt, and positioning assemblies matched with the fixing seats are arranged at the pausing positions of the fixing seats at two ends of the conveying rail; the positioning assembly comprises a butting plate arranged on the side surface of the conveyor belt, a push plate positioned on one side of the fixed seat is arranged on the conveying track in a sliding manner, and after the fixed seat reaches a specified position, the push plate is stopped, and the fixed seat is abutted with the butting plate on one side through the driving mechanism; the push plate is also provided with a positioning block, and the fixing seat is provided with a positioning groove matched with the positioning block in a clamping way.

The utility model is further characterized in that two abutting plates are symmetrically arranged on two sides of the conveyor belt, guide plates are formed by extending the two abutting plates towards the direction of the fixing seat, and guide grooves in abutting fit with the guide plates are formed on two sides of the fixing seat.

The utility model is further provided with the positioning groove and the positioning block which are in matched conical structures.

The utility model is further provided that a channel for the fixed seat to pass through is formed between the pair of guide plates, and openings at two ends of the channel are outwards unfolded to form a splayed structure.

The utility model is further provided that the driving mechanism is a cylinder.

In summary, the utility model has the following beneficial effects:

compared with the prior art, this application is through setting up of locating component, can finely tune the position of fixing base after the fixing base stops to guarantee that the position after the fixing base stopped at every turn is unanimous all the time, and then guarantee that the relative position between fixing base and the manipulator remains unchanged all the time, thereby let the manipulator can be accurate place the work piece on the fixing base or take out the work piece holder on the fixing base.

The guide plates and the guide grooves on the two sides can play an upward supporting role on the fixed seat, so that the phenomenon that the relative positions of the workpiece and the manipulator are changed due to downward deformation of the conveyor belt caused by downward acting force generated on the fixed seat when the manipulator clamps and places the workpiece is avoided; the fixed seat can be propped against one side of the propping plate by the arrangement of the pushing plate, so that the position of the fixed seat in the left and right directions on the conveyor belt is unchanged after the fixed seat is stopped; and the conical positioning blocks are matched with the positioning grooves, so that the positions of the fixing seats in the front-back direction on the conveyor belt can be finely adjusted and limited, and the influence of the inertia of the conveyor belt after the conveyor belt stops on the positions of the fixing seats is reduced.
