Abstract
A thin-walled cylinder machining fixture comprises a clamp cover and a cushion cover. The clamp cover and the cushion cover are of an annular structure, and the cushion cover is arranged in the clamp cover. A mounting gap used for mounting a thin-walled cylinder is arranged between the clamp cover and the cushion cover, and an opening through groove is formed in the clamp cover along the axis. The thin-walled cylinder machining fixture has the advantages of being simple in structure, high in precision, convenient to manufacture, capable of effectively guaranteeing the machining precision of the thin-walled cylinder and capable of effectively preventing the thin-walled cylinder from being flattened.
Description
Technical field
The present invention relates to machining auxiliary mould technical field, particularly a kind of in thin cylinder process, for the fixture by thin cylinder Set and Positioning.
Background technology
Thin cylinder part has lightweight, compact conformation, take up room the advantage such as little, thus be widely used in Machine Design, but there is a no small difficult problem in thin-wall circular tube kind part in process, the general processing technology of this kind of part is with lathe process, often occur after turning the coaxiality deviation of cylindrical and endoporus greatly, the problem such as the circularity over tolerance of endoporus and cylindrical.The shape of thin-wall circular tube kind part is very responsive for the external force of clamping and cutting, even if adopt the measures such as little clamping force, many clamping points fixture, fine feed, many feeds number of times and little feed, the general axiality of part after processing still can be greater than 0.05mm, cannot meet the requirement of processing precision of products.
Summary of the invention
It is simple that the technical problem to be solved in the present invention is to provide a kind of structure, and clamping is reliable and stable, effectively can ensure the thin cylinder clamp for machining of machining accuracy.
For solving the problems of the technologies described above, present invention employs a kind of thin cylinder clamp for machining, comprise chuck and cushion cover, described chuck and cushion cover are loop configuration, described cushion cover is arranged in chuck, be provided with the assemblage gap for installing thin cylinder between described cushion cover and chuck, described chuck is provided with opening groove along axis.
Structure of the present invention is simple, precision is high, easy to make; Inner hole of workpiece is supported by cushion cover, and workpiece outer wall is protected by having flexible chuck, effectively can ensure the machining accuracy of thin cylinder, and it is flat effectively to prevent thin cylinder from being pressed from both sides.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is chuck right view of the present invention.
In figure: 1, chuck; 2, cushion cover; 3, workpiece; 4, opening groove.
Detailed description of the invention
With reference to Fig. 1 and 2, be a kind of thin cylinder clamp for machining, comprise chuck 1 and cushion cover 2, chuck 1 and cushion cover 2 are loop configuration, cushion cover 2 is arranged in chuck 1, is provided with the assemblage gap for installing thin cylinder, chuck 1 is provided with opening groove 4 along axis between cushion cover 2 and chuck 1.External diameter and workpiece 3 internal diameter of cushion cover 2 match, and support workpiece 3, workpiece 3 outer wall puts chuck 1, then by chuck 1 clamping on the claw of lathe, when clamp chuck 1 time, due to chuck 1 being provided with opening groove 4, chuck 1 produces elastic deformation, and workpiece 3 is fixed clamping.
