Embodiment Construction
[0027] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0028] The clamping and processing method of a large thin-walled tapered sleeve includes the following steps:
[0029] (1) First, clamp and turn the outer conical surface:
[0030] Such as figure 1 As shown, prepare the thin-walled conical sleeve blank to be processed. The blank is a hollow truncated cone. According to the inner diameter of the large end and the small end of the thin-walled conical sleeve to be processed, select the large-end stuffy cover with seam design 2 and the small-end stuffy cover 4, the two ends of the thin-walled tapered sleeve 3 to be processed are processed in advance to match the steps of the big-end stuffy cover and the small-end st...

Abstract
The invention discloses a clamping and machining method for large thin-wall taper sleeves. Large thin-wall taper sleeves are cut repeatedly step by step on the basis of accurate locating to taper sleeves to be machined, and eventually, the accuracy requirements are achieved, and the problems that of difficulty in clamping and machining accuracy control and proneness to deformation of thin-wall taper sleeves are solved. The machining method comprises clamping and turning of outer taper faces, large end clamping and turning of small end internal taper faces of thin-wall taper sleeves, and small end clamping and large end internal taper face turning of thin-wall taper sleeves. The clamping and machining method is particularly applicable to clamping and turning of thin-wall taper sleeves of a great number of imported cone crushers applied in domestic mines at present.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a clamping and processing method of a thin-walled conical sleeve of an imported cone crusher. Background technique [0002] Cone crusher is a kind of equipment mainly used for metal ore crushing. At present, domestic mines use a large number of imported cone crushers. Generally, two such crushers are equipped on the mining-separation production line, which are the key equipment of large mining companies. If these two devices fail at the same time, it will cause the mining company to stop production in the whole mine. For the mining company, it will be an inevitable Estimated major equipment accidents. The thin-walled tin-bronze cone sleeve is installed between the moving cone and the frame of the crusher. It is a sliding bearing that fixes and supports the rotation of the moving cone and is a key component of this crusher. The part has a thin wall,...
