Embodiment Construction

[0013] refer to figure 1 . The universal closing device for spinning the spherical surface of the catheter proposed by the present invention includes a positioning component connected to the main shaft of the lathe through a Morse taper and a spinning component fixed on the tool holder of the lathe. The positioning component is connected to the main shaft of the lathe through the Morse taper mandrel 11 for rotational movement, and the spinning component is fixed on the lathe tool rest and moves in the X and Y directions, so that the pressure of the rollers of the spinning component fixed on the lathe tool rest, Perform rapid spinning and closing forming on spherical conduit closing sleeve parts.

[0014] The positioning assembly includes a Morse taper mandrel 11 connected to the main shaft of the lathe for rotational movement and a mandrel 14 integrally connected with the end face of the front cylindrical step 13. The cone 15 of the taper hole is shaped on its free end to co...

Abstract

The invention discloses a universal closing-up device for a spherical surface of a spinning conduit, which comprises a locating component connected with a spindle of a machine tool through Morse taper, and a spinning component fixed on a knife rest of the machine tool; an expansion bushing (1) sheathed on a spindle cylinder is arranged on a front-end spindle (14) of the locating component; inner conical holes (16) oppositely symmetrical are arranged on the two end tube openings of the expansion bushing (1); moreover, two spherical conduit joint sleeves (12) sheathed on the spindle (14) are expanded, located and clamped into a closing-up nut 3 respectively through a cone (15) on the step end surface of the spindle and a taper plug (2) screwed on the free end of the spindle (14); a spinning roller component (4) is arranged on the free end of a spinning stick (10) of the spinning component; the spinning roller component (4) implements feed motions with the knife rest of the machine tool along X and Y directions; and the rollers implement spinning and closing-up forming on the spherical conduit joint closing-up sleeves (12). The universal closing-up device for the spherical surface of the spinning conduit has the advantages of high efficiency, low cost as well as simple and convenient manufacture and operation.

Description

technical field [0001] The invention relates to a pipe spinning and closing device, in particular to a spinning and closing device for pipe-like spherical parts to be closed on a lathe. Background technique [0002] In the prior art, in order to ensure the universal rotation requirements of the connecting parts of the two conduits, usually some pipe ends at the connecting parts of the conduits are required to be spun into a spherical shape to close. In the prior art, the processing of the spherical shape of the connecting part of the two conduits is generally realized by using a decomposable manual special spinning die. The disadvantages of the decomposable manual special spinning die are that the production efficiency is low, the labor load is large, and the operation is inconvenient. The structure is complicated, the cost is high, and the production preparation period is long. Contents of the invention [0003] The object of the present invention is to provide a univer...
