Embodiment Construction

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Without loss of generality, this embodiment takes the thin-walled elastic support shown in the figure as the main body of description, and describes the tooling for processing and disassembly proposed in this application in detail. As shown in the figure, the inner wall of the thin-walled elastic support 10 is provided with a radially extending limiting portion 11, and one side of the limiting portion 11 has a first thin-walled section 12 extending axially, and the other side has a A second thin-walled section 13 extending axially, the outer end of the second thin-walled section 13 has an end flange 14; in addition, a plurality of circumferentially uniform radial through-holes 15 are opened on the second thin-walled...

Abstract

The invention discloses a thin-wall elastic support, a tooling of the thin-wall elastic support and a processing method of the thin-wall elastic support. The tooling comprises a processing mandrel, abushing and a fastener, wherein a large diameter section and a small diameter section are sequentially arranged in the middle of the processing mandrel, and a first positioning portion is formed between the large diameter section and the small diameter section, so that one side of a limit portion extending radially from the inner wall of a blank to be machined is axially abutted and positioned against the first positioning portion; the outer diameter dimension of the large diameter section of the processing mandrel is adapted to the inner diameter dimension of a first thin wall section of a finished product located on one side of the limit portion; the bushing is used for sleeving on the small diameter section of the processing mandrel, and the inner shaft end of the bushing is provided with a second positioning part so as to be axially abutted and positioned against the other side of the limit portion; the fastener is removably and fixedly connected with the processing mandrel to restrict the axial relative position of the bushing relative to the processing mandrel. The application of the scheme can effectively improve the precision of the finished product of the thin-wall elasticsupport, so as to further ensure the yield of the product.

Description

technical field [0001] The invention relates to the technical field of thin-walled elastic support structure processing, in particular to a thin-walled elastic support, tooling and a processing method thereof. Background technique [0002] The elastic support belongs to the shock absorbing device. Based on the characteristics of no friction and wear of the elastic support, it is widely used in the shock absorbing device in the form of small displacement support. [0003] As we all know, the processing of thin-walled elastic structures requires high precision, such as but not limited to verticality, and its variability during processing. Therefore, in the actual processing process, the above precision requirements cannot be achieved by directly cutting the bar. [0004] In view of this, it is urgent to optimize the processing of the thin-walled elastic support and the tooling of the disassembly process to ensure its accuracy requirements and effectively improve the yield. ...
