Abstract

The invention discloses a fast fixture for a two-sided flat shaft. The two-sided flat shaft is used for positioning and bearing torque in machining or assembling, a bench vice is usually adopted to manually fix the two-sided flat shaft by an enterprise and is difficult to be matched with industrial automation equipment, and therefore the production efficiency of the enterprise is limited. According to the fixture, a fixture body comprises a fixture fixing plate, a fixture cover plate and a fast clamp; the fixture fixing plate is hinged to the side portion of the fixture cover plate; a push rod is arranged on a piston rod of a driving air cylinder in a sleeving mode; an outer locking nut and an inner locking nut lock the push rod from the outer side and the inner side respectively; a first limit rod and a second limit rod form moving pairs with a first limit rod guide hole of the fixture fixing plate and a second limit rod guide hole of the fixture cover plate respectively; the fixing end of the fast clamp is fixed with the fixture fixing plate, and the movable end of the fast clamp is fixed with the fixture cover plate. The fast fixture is provided with a U-shaped plug pin type clamping jaw which can effectively limit the rotation of the two-sided flat shaft; the U-shaped plug pin type clamping jaw is driven by the driving air cylinder, and the automation level of the fixture is improved.

Description

Technical field [0001] The invention belongs to the technical field of clamps, and particularly relates to a clamp for clamping mechanical parts with double-sided flat shaft planes. Background technique [0002] The double-sided flat shaft feature is widely used in all kinds of mechanical parts, especially the basic mechanical parts with couplings on it, which is convenient for subsequent processing and assembly; the double-sided flat shaft is used for positioning and to withstand the torsion during processing or assembly Moment. Due to the large individual differences of conventional parts with double-sided flat shafts, the fixing method often adopted by enterprises is manual fixing with a general bench vise, which is difficult to match with industrial automation equipment, thus limiting the production efficiency of enterprises. Summary of the invention [0003] The purpose of the present invention is to provide a clamp that can quickly clamp the characteristic parts of the doub...
