Key processing mechanism with double milling cutter

Abstract

The invention discloses a key machining device with double milling cutters. The key machining device comprises a machining cutter rest and a workpiece clamp. The machining cutter rest comprises a box and a motor. A driving bevel gear is arranged inside the box and connected with a pair of transition bevel gears and a pair of driven bevel gears. The driven bevel gears are sleeved with output shafts. The milling cutters are arranged on the output shafts. A lower cover plate is arranged at the lower end of the box. The output shafts are supported on the lower cover plate. The tool clamp comprises an installation board and a pair of clamp bases with two or more trapezoidal grooves. Fixing pressing boards are arranged between the adjacent trapezoidal grooves. Two rows of opposite threaded holes are formed in the installation board. Bolts connected with the threaded holes are arranged at the two ends of the clamp bases. Through arrangement of the parallel milling cutters and the tool clamp capable of installing two or more keys at the same time, the motor can synchronize the two milling cutters to rotate, two keys can be machined simultaneously under cooperation of the tool clamp, the clamp assembling time is shortened, and the machining benefits and equipment utilization rate are improved.

Description

technical field [0001] The invention belongs to the technical field of parts, components or accessories; auxiliary operation, and in particular relates to a key processing mechanism equipped with double milling cutters. 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 key processing, most of the keys are still single-piece clamping and milling keys, 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 key machining mechanism with doubl...
