Abstract

The invention discloses a hollow axis pneumatic mouth-tightening / waist-suppressing machine, comprising an outer barrel (6), a hollow piston shaft (7), an upper flange (9), a lower flange (5), an air-controlled valve (17), a clamp head (12), a tapered sleeve (11), a fixing seat (2) and a position controlling contact piece (18), wherein the clamp head (12) is used for clamping a wokpiece; and the tapered sleeve (11) is used for matching with the clamp head (12). The hollow axis pneumatic mouth-tightening / waist-suppressing machine provided by the invention has the advantages of simple structure, small volume, big mouth-tightening force, high precision and low failure rate, and is convenient for maintenance.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a mouth-tightening / waist-tightening device in the production process of detonators. Background technique [0002] At present, in the field of detonator production, the mouth tightening / waist tightening equipment used are all desktop or vertical pneumatic mouth tightening machines, and their working principles are: a solid shaft cylinder drives one or a group of linkages to drive the chuck. The outer tapered sleeve reciprocates, and through the relative movement of the conical part on the chuck and the conical part on the tapered sleeve, the local radial compression of the detonator shell is realized to complete the processing process. However, the mouth-tightening / waist-tightening devices in the prior art all have disadvantages such as large volume, high failure rate, small mouth-tightening force, and low precision of mouth-tightening of the detonator.
