Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The profiled electrode assembly 2 and the projection welder provided according to the embodiment of the present invention are described below with reference to fig. 1 and 2.
As shown in fig. 1 and 2, an embodiment of the first aspect of the present invention provides a special-shaped electrode assembly 2 for a projection welding machine, the projection welding machine includes an upper electrode driving member (not shown in the figure), a lower electrode assembly 3 and an upper electrode assembly, the upper electrode assembly is the special-shaped electrode assembly 2, and the special-shaped electrode assembly 2 includes: a first upper electrode holder 20 transversely mounted on the projection welder, the first electrode holder being provided with an upper electrode head 24; and a second upper electrode mount 22 mounted above the first upper electrode mount 20. The second upper electrode mount 22 may be mounted on the top mount 4 of a projection welder, as shown in fig. 1. The second upper electrode holder 22 is vertically disposed opposite to the first upper electrode holder 20, and is configured to be connected to an upper electrode driving component, and is capable of pushing the first upper electrode holder 20 to move under the action of the upper electrode driving component, and the first upper electrode holder 20 and the second upper electrode holder 22 are split structures.
According to the special-shaped electrode assembly 2 provided by the present application, the base body of the special-shaped electrode assembly 2 is a split structure formed by the first upper electrode base 20 and the second upper electrode base 22. In use, the upper electrode drive directly drives the second upper electrode mount 22 into motion, which then acts on the first upper electrode mount 20, and the force on the first upper electrode mount 20 is then transferred to the upper electrode head 24. This components of an electrode assembly on components of a whole that can function independently sets up can improve the power that last electrode head 24 acted on work pieces such as nut, also play a cushioning effect to the power when the last electrode holder descends, avoid whole last electrode holder direct action on work pieces such as nut to just so reduce the possibility that leads to the nut surface by last electrode problem to be crushed during the welding, guarantee promptly that work pieces such as nut can not be welded the deformation by welding after the projection welding, with this guarantee work pieces such as nut complete shape after the welding, thereby be favorable to the follow-up operation of parts such as nut. For example, for a nut, when the existing scheme adopts the L-shaped special-shaped electrode assembly 2 designed in an integrated manner for welding, the end face of the nut is easily pressed and deformed, after welding, the nut is frequently screwed with smooth teeth, the nut is difficult to thread back, one nut needs to be screwed back for 2-3 times to pass through, a bolt can be screwed in, the thread can be damaged after thread back, and the bolt can be tightened to cause problems. And adopt the split type electrode that this application provided, guaranteed that the nut projection welding back can not welded the deformation to this has reduced the screw tap loss, and experiments show that the part can cancel the hard waste, and other parts hard waste once can.
Further, the second upper electrode holder 22 can be lifted up and down relative to the first upper electrode holder 20 by the upper electrode driving member. That is, the upper electrode driver drives only the second upper electrode holder 22 and not the first electrode holder. During welding, the second upper electrode holder 22 can move downwards under the action of the upper electrode driving member to drive the first upper electrode holder 20 to move the upper electrode head 24 to a proper position, so as to ensure the normal operation of welding. After welding, the second upper electrode holder 22 can be moved upward by the upper electrode driving member to provide a space for the first upper electrode holder 20 to return to the initial state, so as to facilitate the subsequent re-installation of the nut or other workpiece. According to the arrangement, the L-shaped electrode is arranged into two parts which are separated, and only one part (namely the second upper motor base) needs to be driven to move during movement, so that the energy consumption can be reduced.
Further, as shown in fig. 1 and 2, an upper electrode head 24 is disposed on one end of the first upper electrode holder 20, and the second upper electrode holder 22 is disposed corresponding to the other end of the second upper electrode holder 22.

This arrangement enables the end of the first upper electrode holder 20, to which the upper electrode head 24 is attached, to rotate about the rotating shaft 28, thereby achieving the distance adjustment between the first upper electrode holder 20 and the lower electrode.
In the above embodiment, as shown in fig. 1 and 2, the electrode assembly 2 further includes an elastic support 29 supported and mounted on the lower side of the first upper electrode holder 20 between the fixed base 26 and the lower electrode holder 32 for restoring the first upper electrode holder 20 after movement.
In this embodiment, the elastic support 29 can be deformed downward when the first upper electrode holder 20 is subjected to a downward force. Thus, after the external force of the first upper electrode holder 20 is removed, the first upper electrode holder 20 is reset by the upward reset force by the inertial restoring force of the elastic supporting member 29. With this arrangement, the first upper electrode holder 20 can be automatically reset after being rotated downward, and a user does not need to manually reset the first upper electrode holder, thereby simplifying the user operation. Of course, in another embodiment, the elastic support 29 may not be provided, and may be manually reset by the user after the first upper electrode holder 20 is moved.
Further, as shown in fig. 2, the elastic support 29 includes: an upper guide holder 292 installed on the first upper electrode holder 20, the upper guide holder 292 having a first installation hole therein; a lower guide base 294 fixedly installed below the upper guide base 292, the upper guide base 292 being provided with a second installation hole; and one end of the return spring 296 is fixedly arranged in the first mounting hole, and the other end of the return spring 296 is fixedly arranged in the second mounting hole. This structure can be restored by the restoring spring 296. The upper guide seat 292 and the lower guide seat 294 are arranged to facilitate the fixed installation of the return spring 296 on one hand, and protect the spring on the other hand, so as to provide a guiding function for the compression and rebound of the spring and ensure that the spring is not bent and deformed when stressed.
