Circumferential Feed Cone Friction Mechanical Clutch

Abstract

The invention provides a friction mechanical clutch with a circular feeding conical surface and belongs to the field of manufacturing of mechanical parts. An inclined plane of a wedged block is contacted with a movable steel ball; a small shaft is arranged at the lower part of the movable steel ball; a dynamic clutch is provided with an external conical surface of the dynamic clutch; a static fixed clutch is provided with an internal conical surface of the static fixed clutch; the external conical surface of the dynamic clutch is tightly attached to the internal conical surface of the static fixed clutch; a worm is connected with the dynamic clutch through a worm wheel; the dynamic clutch is connected with a pin shaft and the pin shaft is connected with a main shaft; and a spring is arranged at the bottom of the dynamic clutch. The friction mechanical clutch with the circular feeding conical surface has the beneficial effects that the service life of a cutter is prolonged for more than 80%, the interval time of clamping a work piece is shortened and the working efficiency is improved by 3.5 times; feeding motions in radial and axial directions are realized; particularly, arc-shaped feeding in the axial direction can be realized; a circular track is formed so that technical indexes of turning a circular work piece are realized; when the friction mechanical clutch works, a contact area is large, the transmission strength is great and the needed operation strength is small under the condition that the transmission strengths are the same.

Description

technical field [0001] The invention relates to the field of mechanical parts manufacturing, and specifically refers to the invention of a conical surface friction mechanical clutch for realizing tool spherical trajectory feed processing. Background technique [0002] Ball valve processing and spherical parts processing in the existing spherical valves are generally processed by ball mills and lathe forming knives. The existing problems are long processing cycle and low efficiency. Especially turning into a spherical workpiece, there are more problems. The characteristic of spherical parts is that the outer surface is round and has no positioning surface, so it is very difficult to shape the inner and outer surfaces. In the field of ball valve processing, the best innovation is to improve the fixture, which has not completely solved the fundamental problem of ball valve processing. How to solve the problem of convenient and fast processing of spherical parts is a core tech...
