A hobbing-chamfering-deburring compound machine tool

Abstract

The invention discloses a hobbing-chamfering-burring compound machine tool which comprises a work table and a stand column. A sliding plate is arranged in the stand column, and the side, facing towards the work table, of the sliding plate is provided with a hob knife rest. The hobbing-chamfering-burring compound machine tool further comprises a sliding block and a mounting bracket, wherein the sliding block is arranged in the stand column and is fixedly connected with the sliding plate, and the mounting bracket is installed on the sliding block in a sliding fit mode. A chamfering and burring tool is arranged at the end, facing towards the work table, of the mounting bracket, and a drive mechanism used for driving the mounting bracket to slide along the sliding block is arranged at the other end of the mounting bracket. The chamfering and burring tool comprises a knife rest fixedly installed on the mounting bracket, the knife rest is provided with a knife shaft which is in rotary fit with the knife rest and is located in the vertical direction, the knife shaft is sleeved with a spacer bush synchronously rotating with the knife shaft, and the two ends of the spacer bush are each sleeved with a chamfering and burring cutter assembly synchronously rotating with the spacer bush. Each chamfering and burring cutter assembly comprises a chamfering cutter and a burring cutter, and the two chamfering cutters in the two chamfering and burring cutter assemblies are located between the two burring cutters.

Description

technical field [0001] The invention belongs to the technical field of machine tool equipment, and in particular relates to a hobbing-chamfering-deburring compound machine tool. Background technique [0002] The gear hobbing process generally includes multiple processes such as rough rolling → chamfering → deburring → fine rolling. Since the existing gear hobbing machine cannot complete the chamfering and deburring process, the existing gear hobbing production line needs to include at least two gear hobbing machines and one chamfering and deburring machine. The chamfering and deburring machine is located between the two gear hobbing machines. One of the gear hobbing machines is used for rough hobbing of gear workpieces, and the other gear hobbing machine is used for finish hobbing of gear workpieces. Although such a gear hobbing production line can meet the use requirements to a certain extent, it will not only increase equipment investment, but also the workpiece needs to ...

Problems solved by technology

Since the existing gear hobbing machine cannot complete the chamfering and deburring process, the existing gear hobbing production line needs to include at least two gear hobbing machines and one chamfering and deburring machine. The chamfering and deburring machine is located between the two gear hobbing machines. One of the gear hobbing machines is used for rough hobbing of gear workpieces, and the other gear hobbing machine is used for finish hobbing of gear workpieces

Although such a gear hobbing production line can meet the use requirements to a certain extent, it will not only increase equipment investment, but also the workpiece needs to be clamped many times, and the machining accuracy cannot be guaranteed.
