Expanding sleeve quick-change type general internal tooth inserting fixture

Abstract

The invention discloses an expansion sleeve quick-change universal inserting tooth clamp, which comprises an expansion sleeve, a clamp body, a stretch sleeve and an adapter plate; the adapter plate is supported and fixed on the work table; the lower end of the clamp body and the adapter plate Cooperate; there is a pull plate in the inner cavity of the lower end of the fixture body, a guide sleeve passes through the inner hole on the outer edge of the pull plate, the upper end of the guide sleeve passes through the fixture body and contacts the stretch sleeve, and a tension pulley is set in the center hole of the fixture body above the pull plate. Bolt, the tension bolt is provided with a stopper; the inner cavity of the upper end of the fixture body is provided with a support pad, and the upper end surface of the support pad is supported by a quick-change flat pad; Cooperate with the inner tapered surface of the upper end of the fixture body; the lower end of the expansion sleeve is inserted and connected with the tension sleeve; the tension sleeve is connected with the pull plate through the guide sleeve, and the lower end of the tension bolt on the pull plate passes through the center hole of the pull plate and the inside of the work table The cylinder assembly connection. The present invention does not need to re-align the fixture when changing production, which saves a lot of time for changing production.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an expanding sleeve quick-change universal internal tooth clamp. Background technique [0002] There is a rigid connection between the expansion sleeve and the oil cylinder of the existing internal tooth jig. This structure has the following disadvantages: it cannot be quickly changed and produced, and the original jig must be disassembled and replaced with another set of jigs; it cannot be used on different types of machine tools. It is universal, a set of fixtures can only be used on one type of machine tool; it cannot meet the diameter machining of all ring gears. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides an expanding sleeve quick-change universal internal tooth clamp. The fixture locates and clamps the outer circle of the workpiece quickly and stably. When changing production, there is no...
