Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides the pipe fitting clamping apparatus that on a kind of multiple tube spinning machine, structure is improved, and which increases bite, increases clamping dynamics, thus prevents the composite water pipe clamped from rotating.
Technology solution of the present utility model is as follows:
The pipe fitting clamping apparatus that on a kind of multiple tube spinning machine, structure is improved, comprise head tree, the two opposite side walls of head tree is fixed with the secondary column of L-type, the upper end of head tree forms the gathering sill running through head tree top end face, the top end face of head tree has been bolted top cover, leading screw is plugged with in the gathering sill of head tree, the lower end of leading screw is plugged in the bottom surface of head tree gathering sill, upper end is fixedly connected with handwheel through top cover, described leading screw forms the shaft shoulder, and the upper surface of the shaft shoulder is resisted against on top cover; Leading screw is plugged with support bar, the gathering sill that head tree is stretched out at the two ends of support bar is fixed on clamping plate, clamping plate are plugged on head tree, the two side at clamping plate two ends is fixed with the first voussoir, first voussoir forms downward opening first V-type groove, described secondary column is fixed with the second voussoir, and the second voussoir forms the second opening up V-type groove, the second V-type slot is in the downside of the first V-type groove.
First V-type groove of described first voussoir and the second voussoir and the inclined-plane of the second V-type groove are pasted and is fixed with leather packing.
Described support bar is positioned at the downside of clamping plate, and the upper surface of clamping plate is fixed with bracing piece, is screwed onto on screw mandrel in the gathering sill that bracing piece is plugged on head tree.
The width of described clamping plate is greater than the thickness of the second voussoir on secondary column.
The beneficial effects of the utility model are:
It is by increasing bite, and utilizes mechanical clamping structure to replace cylinder clamping, and clamping dynamics is all improved with stable, thus can prevent the composite water pipe clamped from rotating at spinning process, ensures the spinning quality of composite water pipe.
