Turning device for chamfer at gear tooth end

Abstract

The invention discloses a turning device for a chamfer at a gear tooth end. The device comprises a motor, a three-jaw chuck, a chamfering tool, tool rests and a base, wherein a cooling unit is arranged at the front end of the three-jaw chuck and can spray a coolant to a cutting area; the three-jaw chuck rotates around its axis under the driving of the motor; a workpiece is clamped in the three-jaw chuck; and according to a pair of tool rests capable of adjusting the relative position of the tool and the workpiece axis, the angle and position of the tool can be adjusted conveniently, the tool can be controlled to rotate for operation stably, flying chips can be washed away when the coolant is sprayed, and cleanness of a working environment is guaranteed. Therefore, the device has the advantages of being high in efficiency, convenient to use, high in processing quality, good in safety and the like.

Description

technical field [0001] The invention relates to the technical field of turning devices, in particular to an efficient device for gear tooth end chamfering and turning. Background technique [0002] For safety and other considerations, mechanical parts often form chamfers on their edges to make their edges smoother or at least not sharp, so as to prevent users from accidentally scratching and bumping and causing safety concerns. The sharp corners of gears It is also easy to cause scratches on the surfaces of the gears that mesh with each other. At present, the common tooth end chamfering method is that the tool rotates continuously, the workpiece is indexed intermittently, and the workpiece is fixed during the cutting process. After cutting a tooth, the indexing device is used to turn a tooth, and then the next tooth is processed, which is discontinuous. Cutting, this processing method involves factors such as indexing accuracy, intermittent transmission, and indexing toolin...

Problems solved by technology

At present, the common tooth end chamfering method is that the tool rotates continuously, the workpiece is indexed intermittently, and the workpiece is fixed during the cutting process. After cutting a tooth, the indexing device is used to turn a tooth, and then the next tooth is processed, which is discontinuous. Cutting, this processing method involves factors such as indexing accuracy, intermittent transmission, and indexing tooling adjustment, resulting in defects such as low processing efficiency and low precision

There is also a method of chamfering with a grinding wheel. If it is manually hand-held grinding, the work intensity is high, the precision is low, and the quality is poor.
