Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model is used for feeling relieved to disc type work and clamping, to guarantee that workpiece reliably can carry out following process.Described disc type work comprises one to be had the body 100 of flat end face and is arranged at the body central through hole vertical with its flat end face 200.
With reference to Fig. 1, Self-centering device comprises connection seat 1, positioning seat 2, pull bar 3, Compress Spring 4 and sliding sleeve 5 etc.
The bottom surface of connection seat 1 is the conjunction plane for being connected with lathe ring flange, as shown in Figure 1, during use connection seat 1 by some screw lock on lathe ring flange 6.This connection seat 1 plays the overall effect fixed and locate.Connection seat 1 is provided with boss 7, is provided with sliding sleeve chamber 8 in boss 7.Positioning seat 2 is located on boss 7, and the end face of positioning seat 2 is the plane of orientation for fitting with the flat end face of disc type work, is provided with the perforation 9 that shape is mated with sliding sleeve chamber 8 in positioning seat 2.Pull bar 3 is threaded onto on connection seat 1, and pull bar 3 overlaps with the central shaft in sliding sleeve chamber 8, and pull bar 3 is provided with quick change pressing plate 10 from one end that sliding sleeve chamber 8 is stretched out.Compress Spring 4 to be located in sliding sleeve chamber 8 and to be placed on pull bar 3, and its one end abuts with at the bottom of the chamber in sliding sleeve chamber 8, and the other end is set to movable end.In order to avoid Compress Spring 4 ejects, be provided with clip slot 11 at the bottom of the chamber in sliding sleeve chamber 8, one end of Compress Spring is clamped in clip slot 11.The shape of sliding sleeve 5 is mated with sliding sleeve chamber 8, and sliding sleeve 5 to be located in sliding sleeve chamber 8 and to be placed on Compress Spring 4, and the inner side of sliding sleeve 5 abuts with the movable end of Compress Spring 4.
