Embodiment Construction
[0034] This embodiment is a kind of inner support tooling used for machine trimming of cylindrical parts whose wall thickness is less than or equal to 3mm. There are two inner support toolings, which are used in pairs.
[0035] This embodiment includes a push rod 1 , a sleeve 2 and a shaft 3 . The outer tapered section of the push rod 1 is loaded into the elastic section of the sleeve 2, and the outer tapered surface of the push rod is attached to the inner tapered surface of the elastic section of the sleeve 2. One end of the shaft 3 is loaded into the push rod and the sleeve.
[0036] The sleeve is made of elastic steel, 65Mn is used in this embodiment; the push rod 1 and sleeve 2 are made of 45# steel.
[0037] The sleeve 2 is a cylindrical part and is divided into an elastic section and a rigid section. The center of the end plate of the rigid section has a shaft hole for installing the shaft 3, and the shaft hole and the shaft are screwed together; the inner end surface...

The invention relates to an inner support tool for machining and trimming of a cylindrical part. The tool is characterized in that an outer conical section of a push rod is arranged in an elastic section of the sleeve, the outer conical surface of the push rod is attached to an inner conical surface of the elastic section of the sleeve, one end of a shaft is arranged in the push rod and the sleeve, the sleeve is a cylindrical part and is divided into the elastic section and a rigid section, the elastic section consists of a plurality of elastic laths, a distance between side surfaces of adjacent elastic laths is b, an elastic lath expansion hole with the diameter of d is formed at a root of each cutting seam, the elastic laths are close to a conical surface contracted in an inner surface of an end opening of the sleeve, the conical degree of the conical surface is theta, and the length of the conical surface is one half of the axial length of the elastic laths. During use, the cylindrical part is supported through expansion and contraction of the elastic laths, machining precision is improved, cutting operation is simple and rapid, efficiency is improved, and labor intensity is reduced.
Description
technical field [0001] The invention relates to the machinery manufacturing industry, in particular to design and manufacture a machine-trimmed inner support tooling for cylindrical parts with a wall thickness not greater than 3.0mm that can be installed on a numerically controlled lathe. Background technique [0002] At present, the most commonly used domestic thin-walled spinning cylindrical parts with a wall thickness of no more than 3.0mm adopt the following two structures: the multi-top automatic centering adjustable structure and the circumferential split-type adjustable structure. structure. [0003] The application number is 201610749071.0, and the announcement number is CN106271354B "A Self-Centering Internal Support", which is a self-centering adjustable structure support with multiple top blocks, and the telescopic screw structure is installed on the circumferential surface of the guide ring. In the guide chute, when working, the movement of the screw realizes th...
