Abstract

The invention discloses a thin-wall tube body fastening device which relates to a tool for processing a thin-wall tubular work piece on a lathe, and comprises a mandrel; a spacer is arranged in the center of the mandrel; a left baffle, a left conical sleeve, a left pressure block and a retaining ring are sequentially arranged on the mandrel on the left side of the spacer; a right baffle, a right conical sleeve and a right pressure block are sequentially arranged on the mandrel on the right side of the spacer; the spacer, the left baffle, the left conical sleeve, the left pressure block, the right baffle, the right conical sleeve and the right pressure block can slide on the mandrel; axial gaps are respectively arranged between the left baffle and the left conical sleeve and between the right baffle and the right conical sleeve; the retaining ring is fixedly arranged on the mandrel; a fastening nut is arranged on the mandrel on the right side of the right pressure block; and circular Half blocks which are provided with conical inner holes, and comprise a plurality of semi-rings are respectively arranged on the outer peripheral conical surfaces of the left conical sleeve and the right conical sleeve in a matching way. First, a thin-wall tube body is fastened on the thin-wall tube body fastening device, the thin-wall tube body can be fixed only after the mandrel is fixed on the lathe, the fixation to the thin-wall tube body is simple, the axiality of both ports of the tube body is high, the tube body does not deform when in processing, and the processing precision is high.

Description

technical field [0001] The invention relates to a lathe tool for machining thin-walled cylindrical workpieces, in particular a fastening device for a thin-walled cylindrical body. Background technique [0002] We know that when lathes are used to process thin-walled cylindrical workpieces, it is difficult for the lathe to fix the thin-walled cylinder due to the thin wall and long cylinder, the coaxiality of the two ports of the cylinder is low, and the cylinder is deformed during processing. Large, low machining accuracy. Contents of the invention [0003] The technical problem solved by the present invention is to solve the problems that it is difficult to fix the thin-walled cylinder with a lathe, the coaxiality of the two ports of the cylinder is low, the deformation of the cylinder is large during processing, and the processing accuracy is low. The body is fixed easily, the coaxiality of the two ports of the cylinder is high, the cylinder is not deformed during proces...
