Further, multiple ejection cylinders are additionally provided with below the bottom plate, are connected on the piston rod of the ejection cylinder
There is mandril, the bottom plate is equipped with through hole, and the mandril extends to the lower section of connected components to be welded through through hole.Eject cylinder
Setting first up to eject one end distance after the completion of Product jointing under mandril effect, more convenient product component is from frock
On remove.
Further, the top of the supporting block is equipped with jack, limited post is plugged with the jack, when to be welded
When component is positioned in supporting block, the spacing round tube hole default in the support plate of connected components to be welded of the limited post grafting
It is interior.Due to being preset with round tube hole in the support plate of connected components to be welded, so increasing spacing rod structure in corresponding supporting block, limit
Position column insertion round tube hole is spacing so that the spacing of whole connected components to be welded more stablizes, is accurate.
As an improvement, the detent mechanism for positioning connected components to be welded is additionally provided with the bottom plate, the localization machine
Structure includes cylinder, positioning pluging rod, connecting plate and support base, and the support base is connected on bottom plate, and the cylinder passes through company
Fishplate bar is located on support base, and the support base is equipped with through hole, and the positioning pluging rod is slidably located in through hole, and described
Positioning pluging rod one end and cylinder piston rod connect, the other end be used for default casing grafting on connected components to be welded it is spacing.
Further, first position-limit mechanism further includes guide pad, and the guide pad is located at support base close to set
On the side wall of pipe one end and it is socketed on the outer wall of positioning pluging rod.The setting of the guide pad causes the first of the first position-limit mechanism to determine
Position inserted link concentricity when spacing with casing grafting is more accurate, prevents the first positioning pluging rod from deflecting during stretching out, from
And cause to produce interference in grafting.
