Description

Puppet welding auxiliary extension welding mechanism

Technical Field

The utility model relates to a puppet welds supplementary extension welding mechanism belongs to the machine and adds the welding field.

Background

The welding gun utilizes the heat generated by the high current and high voltage of the welding machine to gather at the welding gun terminal, melts the welding wire, the melted welding wire permeates to the part needing to be welded, and the welded objects are firmly connected into a whole after being cooled.

In the puppet welding process, aiming at a part (such as an automobile front windshield) with a similar U-shaped structure, the problem that a welding gun cannot extend into the part due to limited space of a lower welding point of the U-shaped structure often exists. At this moment, the welding gun is often manually used for welding, so that the welding efficiency is low, the welding precision is not high, and the welding quality of the product cannot be ensured.

SUMMERY OF THE UTILITY MODEL

This in order to solve above-mentioned technical problem, the utility model provides a puppet welds supplementary extension welding mechanism welds the solder joint that has similar U-shaped structure below welder can not reach in the part specially, improves work efficiency, guarantees the welding precision.

In order to realize the above object of the utility model, the utility model provides a puppet welds supplementary welding mechanism that extends, including the supporting seat, its characterized in that: the upper end of supporting seat is provided with extends welding set, should extend welding set and include two and extend the welding arm, and these two are extended the welding arm and are cut the fork articulated through the axis of rotation that passes their middle part, and these two front end inboards that extend the welding arm are provided with the electrode cap relatively, are provided with insulating gasket between these two tails that extend the welding arm, are provided with the return spring who connects two extension welding arms on this insulating gasket.

By adopting the scheme, the puppet auxiliary extending welding mechanism is specially installed on the welding tool for parts with similar U-shaped structures, and the support seat can be slidably connected on the welding tool through a slide rail, so that the position of the auxiliary extending welding mechanism can be conveniently adjusted to a welding point. Two extension welding arms are stretched to the welding point that welder can not reach, and two electrodes of welder are drawn close with the afterbody extrusion of two extension welding arms with the afterbody contact of two extension welding arms to let two electrode caps of front end draw close and accomplish welding action (the electric current transmits the electrode cap through extending the welding arm). When the welding is finished, the welding gun leaves, and the two electrode caps are automatically separated under the action of the return spring.

In the scheme, the method comprises the following steps: the supporting seat is an L-shaped supporting frame formed by connecting a vertical supporting plate and a horizontal supporting plate.

In the scheme, the method comprises the following steps: the both sides at the upper portion back of vertical support plate are provided with the axis of rotation installing support respectively, axis of rotation installing support upper end extends to vertical support plate's top, the upper end at the axis of rotation installing support of both sides is installed at the both ends of axis of rotation.

In the scheme, the method comprises the following steps: two extend the welding arm and distribute from top to bottom, the upper portion from the top down of vertical support plate is provided with a row of bolt holes, and the front portion is located the below of the extension welding arm of downside and is provided with the piece that stops, and this stops the piece and passes through bolted connection in this row of bolt holes. This controls the downward movement of the extension welding arm. Thereby controlling the opening degree of the two extended weld arms.

In the scheme, the method comprises the following steps: and a proximity switch is arranged on the side wall of the extension welding arm.

In the scheme, the method comprises the following steps: and the opposite sides of the tail parts of the two extending welding arms are respectively provided with a backing plate.

Has the advantages that: the utility model discloses a puppet welds supplementary extension welding mechanism and for welder's extension, uses to the solder joint that welder can not reach, improves welding efficiency, guarantees the welding precision.
