Embodiment Construction

[0010] As shown in Figures 1 and 2, the present invention inserts a pull rod 2 inside the expansion cover 1, one end of the insertion hole inside the expansion cover 1 is tapered, and an inclined boss 3 is provided on the outer wall of the expansion cover 1, The outer wall of the extension sleeve 1 with one end tapered is equally divided into four parts, one end of the tie rod 2 is tapered, and the taper at one end of the pull rod 2 matches the tapered insertion hole inside the expansion sleeve 1 . Through the above settings, the present invention is used for the lathe to support and clamp the inner hole of the workpiece. The workpiece to be processed is inserted on the inclined boss 3, and the pull rod 2 is tightened so that the inclined boss 3 on the expansion sleeve 1 is aligned. Outer expansion, the outer diameter of the inclined boss 3 fully contacts the inner wall of the inner hole of the workpiece, and the workpiece can be supported and clamped to be processed.

Abstract

The invention discloses a novel inner diameter expanding clamping tool. The novel inner diameter expanding clamping tool is characterized in that a drawbar is inserted into an expanding sleeve in a penetration manner, wherein one end of a penetrating hole inside the expanding sleeve is tapered; an inclined boss is arranged on the outer wall of the expanding sleeve; the outer wall of the expanding sleeve with a tapered end is equally divided into four parts; one end of the drawbar is tapered; the tapered end of the drawbar is matched with the tapered penetrating hole inside the expanding sleeve. The novel inner diameter expanding and clamping tool is used for supporting an inner hole of a lathe processing workpiece, convenient to clamp, time-saving and labor-saving in clamping, firm in clamping and convenient for processing production of the workpiece, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical processing tool, in particular to a novel internal diameter expansion clamping tool. Background technique [0002] The inner hole support processing in the prior art is mostly directly clamped by the lathe chuck, which sometimes damages the outer diameter of the workpiece, and the fixation is not firm, which affects the processing quality, and the clamping is troublesome, which reduces the productivity. Contents of the invention [0003] The purpose of the present invention is to provide a new inner diameter expansion clamping tool that is convenient for fastening and clamping. [0004] In order to achieve the above object, the present invention interpenetrates a pull rod inside the expansion sleeve. One end of the insertion hole inside the expansion sleeve is tapered, and an inclined boss is provided on the outer wall of the expansion sleeve. One end is a tapered outer wall of the expansion sleeve. It is equall...
