Utility model content

The technical problem to be solved by the utility model is to provide a gear shaft hobbing fixture with simple structure and capable of firmly clamping workpieces.

In order to solve the above technical problems, the technical solution of the present utility model is: a gear shaft hobbing fixture, including a clamp body, a top, a clamping sleeve and a stopper; the clamp body includes a cylinder with a central taper hole , There is a ring of bosses around the bottom of the cylinder, and a plurality of through holes for bolt installation are arranged on the bosses, a downward longitudinal groove is arranged on the upper end of the cylinder, and a fastening ring is installed on the groove walls on both sides. Bolt; the top includes a top head, a top body and a threaded end, the size and Morse taper of the top body match the central taper hole of the clamp body, and the threaded end of the top passes through the taper hole of the clamp body and passes through the nut and The gasket is fixed on the bottom of the clamping body; the clamping sleeve is an open annular sleeve, and the two ends of the ring are provided with screw holes on the upper part of the annular sleeve, and one end of the sleeve wall is also provided with There is a bolt installation step, which is convenient for screwing the bolt into the screw hole from here, so as to connect the two ends of the annular sleeve. There are two longitudinal process grooves at intervals on the outer side of the sleeve wall. There is a screw hole on the mounting surface, and a downwardly protruding block is installed in the screw hole; the clamping sleeve is located on the upper end surface of the clamp body, and the stopper is inserted into the groove on the upper end surface of the clamp body, and Fastening is carried out by means of bolts on the sides of the channel.

When in use, first install and fix the clamp body on the working turntable of the gear hobbing machine through multiple installation through holes on the lower boss of the clamp body with bolts, and then insert one end of the gear shaft of the workpiece to be processed into the clamping sleeve, so that the end surface of the gear shaft Align the center hole with the center head, and then tighten the bolts on the upper part of the clamping sleeve, so that the clamping sleeve hugs the outer surface of the gear shaft, so that the gear shaft is firmly fixed on the fixture, which is convenient for processing the gear shaft, both The quality of the workpiece is guaranteed, and the work efficiency can be improved.
