Abstract

The present invention discloses method and device for machining key slot in gear inner hole. The method includes fixing one support on the press bench, setting the workpiece on the support, inserting the conical guide part of the combined tool into the inner hole of the workpiece, pressing the combined tool to pass through the inner hole with pressure mandrel, cutting the key slot with the pushing broach in the combined tool, and loosening the mandrel to unload the workpiece and the combined tool to complete the machining. The device specially for machining key slot in gear inner hole includes a pressure mandrel on a press, a support on the bench of the press, and a combined tool. The combined tool consists of a pushing broach, a broach pouch and a locking screw for connection. The present invention is used in cutting single key slot in inner hole of gear of non-ferrous metal and plastic.

Description

Technical field:

[0001] The invention relates to a method and a device for processing a gear inner hole keyway. Background technique:

[0002] The gear is the basic part of the machine, and most of the gears are connected to the shaft through a key connection, so the processing quality of the keyway is very important. The traditional processing techniques include: using a broach to pull the keyway, using a slotting machine to insert the keyway, and wire cutting, electric spark, laser, etc. Among these traditional processing techniques, broaching with broaching machine is characterized by high productivity, but if the number of workpieces to be broached is small, the utilization rate of broaching machine is low, which is easy to cause equipment waste; second, the processing range is wide, and the machine tool The structure is simple and the operation is convenient; the third is that the structure of the broach is complex, and a special broach is required for broaching each s...
