Abstract

The utility model relates to a copying lathe spherical surface device which comprises a copying body and a guiding strut rod, wherein, one side of the copying body is provided with a crown face the semidiameter of which is equal to the spherical surface semidiameter of a workpiece, the corresponding other side is provided with a taper shank, and one end of the guiding strut rod is provided with an idler wheel. The copying lathe spherical surface device has simple structure and is used for copy turning of a spherical surface workpiece, when in processing, the copying body is inserted into a lathe tailstock, the guiding strut rod and a turning tool are together clamped on a compound rest, a slide carriage is operated by both hands, the idler wheel and the crown face keep clinging and feeding, thereby processing the spherical surface. When the device is used, the operation is easy, the machining precision and the production efficiency of the spherical surface can be improved, and the investment is little and the cost is low, the copying lathe spherical surface device is particularly suitable for the mass production of small and medium-sized enterprises.

Description

Profile lathing sphere device

Technical field

The utility model relates to a kind of turning processing profiling jig, particularly profile lathing sphere device.

Background technology

In the man-hour that adds of small lot sphere workpiece, generally be on engine lathe, with the hands to operate slide carriage, carry out the horizontal and vertical feeding of lathe tool simultaneously, operation easier height not only, labour intensity is big, and the sphere machining accuracy is difficult to guarantee, production efficiency is also low, as adopt special equipments such as Digit Control Machine Tool, then then exist to have high input the problem that cost is high for the small lot batch manufacture of medium-sized and small enterprises.

The utility model content

The purpose of this utility model is to provide a kind of both had been convenient to operation, can improve machining accuracy and production efficiency, the profile lathing sphere device that can reduce input again, reduces cost.

The technical solution of the utility model is: this device is made of imitation body and guide stanchion, one side of described imitation body is provided with arc surface, its arc radius R equals workpiece spherical radius R1, a side relative with arc surface of imitation body is provided with taper shank, the center line of this taper shank is by the center of arc surface, taper shank inserts the tail stock pilot hole, one end of described guide stanchion is provided with roller, guide stanchion and lathe tool are clamped on the lathe slide carriage jointly, and described roller and lathe tool cutter head line are parallel to the lathe spindle center line.

The arc surface of described imitation body can be spill arc surface or convex shaped arc face.

During work, imitation body is contained on the tailstock, and the Center Symmetry Plane of described arc surface is by the lathe spindle center line, and perpendicular to the lathe guide level, adjustment tailstock position make the roller on the guide stanchion be adjacent to arc surface, and point of a knife is in the initial Working position of workpiece; After the driving, still with the hands operate slide carriage, as long as the control roller is adjacent to arc surface and moves, then point of a knife track and roller track are in full accord, be the circular arc of radius R, workpiece just is processed into the sphere of radius R 1=R in rotation, the concave, convex arc surface of imitation body is respectively applied for processing spherical outside surface and Internal Spherical Surface.The utility model is simple in structure, and processing ease can improve the sphere machining accuracy, enhance productivity, in especially being fit to, the small lot batch manufacture of small enterprise, and less investment, cost is low.
