Keyway processing device

Abstract

The invention discloses a keyway processing device, which includes a processing tool and a workpiece fixture. The processing tool includes a housing and a motor. The housing is provided with a driving gear connected to the motor. The driving gear is connected with a pair of driven gears, and the driven gear is set on the There is an output shaft, the other end of the output shaft is provided with a milling cutter, the lower end of the housing is provided with a lower cover plate, the output shaft is supported on the lower cover plate, the workpiece fixture includes a mounting plate and a pair of fixture seats, and there are no less than 2 fixture seats on the fixture seat. There are three trapezoidal grooves, a fixed platen is provided between adjacent trapezoidal grooves, two rows of oppositely arranged threaded holes are arranged on the mounting plate, and bolts connected with the threaded holes are arranged at both ends of the fixture seat; There are side-by-side milling cutters and tooling fixtures that can install 2 or more keys at the same time. The motor can synchronize the rotation of 2 milling cutters. With the cooperation of tooling fixtures, two keys can be processed at the same time, reducing the fixture assembly time. , Improve processing efficiency and equipment utilization.

Description

technical field [0001] The invention belongs to the technical field of parts, components or accessories; auxiliary operation, and in particular relates to a keyway processing device. Background technique [0002] In modern production, machine tool fixtures have become an indispensable process equipment in machining as a part of machine tools. When the production batch of the workpiece is large, in addition to considering the machining accuracy of the workpiece, we also need to consider the productivity and economical issues. Therefore, a special fixture specially designed for a certain process of a certain part is often used to clamp the workpiece. In the existing keyway processing, most of the keyways are still single-piece clamping and milling keyways, which has low production efficiency and low precision. Contents of the invention [0003] In view of this, the object of the present invention is to provide a keyway processing device, the keyway processing device is prov...

When the production batch of workpieces is large, in addition to considering the machining accuracy of workpieces, we also need to consider productivity and economic issues, so we often use special fixtures specially designed for a certain process of a certain part to clamp the workpiece. In the existing keyway processing, most of the keyways are still single-piece clamping and milling keyways, which has low production efficiency and low precision.
