Abstract
The invention discloses a lathe fixture for machining a conduit coaxially. The fixture comprises a clamping plate ejector pin and a nail end ejector pin. The clamping plat ejector pin comprises a bush and a mandrel. A step internal hole with small diameter at the front end and large diameter at the rear end is formed in the bush. An embedding part is arranged at the front end of the bush. The front end face of the embedding part is a tooth face meshing with the end face of a conduit. The mandrel is arranged in the step internal hole. The head end of the mandrel is conical, and the tail end of the mandrel is a cut-off segment. The head end of the mandrel extends out from the end face of the embedding part. Jump concentricity with the internal hole is guaranteed when the excircle of the head of the conduit is machined, clamping speed of parts is increased, and machining efficiency is improved.
Description
Technical field
The present invention relates to a kind of turning attachment for cylindrical processing, particularly relate to the turning attachment of the coaxial processing of a kind of conduit.
Background technology
The working method of tradition lathe is by the lathe chuck holding workpiece, and the other end to workpiece machines then, and adopts the catheter product of powder metallurgical technique sintering, is adding man-hour, needs to guarantee that the jumping axiality of its head cylindrical and endoporus is less than 0.03mm.Lathe chuck is difficult to guarantee the axiality of lathe spindle and conduit endoporus to the clamping of conduit, the cylindrical that processing obtains and the axiality of endoporus also can't guarantee, on the other hand, the surface damage that clamps and can cause the conduit bare terminal end of chuck, therefore when the catheter fabrication of routine, all be to adopt peripheral milling to guarantee this dimensional requirement.But adopt the peripheral milling working (machining) efficiency lower, processing cost is also big than machined into.
Summary of the invention
The turning attachment that the purpose of this invention is to provide the coaxial processing of a kind of conduit guarantees that the catheter head cylindrical adds the jumping axiality of man-hour and endoporus, improves working (machining) efficiency, reduces cost.
Technical scheme of the present invention is such: the turning attachment of the coaxial processing of a kind of conduit, it is characterized in that, these anchor clamps comprise chuck thimble and tail end thimble, described chuck thimble comprises sleeve and plug, it is little to be provided with point diameter in the described sleeve, the inner bore of step that the rear end diameter is big, the front end of described sleeve is provided with the portion of inlaying, the described front end face of inlaying portion is the flank of tooth that is meshed with the conduit end face, described plug is arranged in the inner bore of step, the plug head end is conical head, and the plug tail end is for ending section, and described plug head end stretches out the end face of the portion of inlaying.
In a specific embodiment of the present invention, described plug tail end is provided with thrust spring.
In another specific embodiment of the present invention, described material of inlaying portion and plug is the WC carbide alloy.
The advantage of technical scheme provided by the present invention is, behind the lathe chuck clamping chuck thimble, drives conduit rotation to be processed by the barrel forward end flank of tooth, has guaranteed the jumping axiality between conduit cylindrical turning processing back and endoporus; These anchor clamps compress conduit by the tail end thimble, unclamp the afterbody thimble after the processing, and the plug of chuck thimble ejects, and conduit namely drops from the chuck thimble, have accelerated clamping and taking off of processing parts when guaranteeing axiality, improve working (machining) efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is chuck thimble structure schematic diagram;
Fig. 3 is for inlaying portion's front end face schematic diagram.
The specific embodiment
The invention will be further described below in conjunction with embodiment, but not as a limitation of the invention.
See also Fig. 1, Fig. 2 and Fig. 3, the turning attachment of the coaxial processing of conduit comprises chuck thimble 1 and tail end thimble 2, tail end thimble 2 is fixed on the lathe tailstock 6, the diameter of tail end thimble 2 is greater than the diameter of bore of conduit 7 to be processed, in order to accelerate the translational speed of tailstock 6, raising clamps efficient, and originally the tailstock move mode that rotates for handwheel was transformed into handle push-and-pull locking structure.Chuck thimble 1 comprises sleeve 3 and plug 4, lathe chuck 8 clamping chuck tailstock barrel tubes 3, it is little to be provided with point diameter in the sleeve 3, the inner bore of step 31 that the rear end diameter is big, the front end of sleeve 3 is provided with the portion of inlaying 32, the front end face of inlaying portion 32 is the flank of tooth that is meshed with conduit 7 end faces, plug 4 is arranged in the inner bore of step 31, plug head end 41 is conical head, plug tail end 42 is for ending section, the leading portion diameter of plug 4 diameters and sleeve 3 inner bore of step 31 is quite and greater than the diameter of bore of conduit 7 to be processed, plug is suitable by the back segment diameter of section 42 diameters and inner bore of step 31, plug head end 41 stretches out the end face of the portion of inlaying 32, the tail end 42 of plug also is provided with thrust spring 5, when conduit 7 clamps, adjust lathe spindle, the position of chuck thimble 1 and tail end thimble 2 is to reach the axiality requirement, promoting lathe tailstock 6 withstands conduit 7 endoporus to be processed and compresses locking, conduit 7 front ends are pressed into inner bore of step 31 with plug 4, power is held in thrust spring 5 compressions of plug tail end 42, after the portion's of inlaying 32 drive conduits, 7 rotation turning processing, unclamp lathe tailstock 6, thrust spring 5 ejects plug 4, and conduit 7 natures drop from anchor clamps.In order to guarantee the durability of anchor clamps, the portion of inlaying 32 of sleeve 3 is the WC carbide alloy with the material of plug 4.
