Description

Technical Field

[0001] The utility model relates to the technical field of gear shaping machines, and in particular to an automatic tool position adjustment structure of a gear shaping machine for reducing machine production. Background Art

[0002] During the production process of reducers, the gears inside them need to be processed by a gear shaping machine. A gear shaping machine is a metal cutting machine that uses a gear shaping cutter to process internal and external spur and helical cylindrical gears and other toothed parts according to the spreading method. When the gear shaping machine is processing gears, due to the wear of the gear shaping cutter tip, the tool needs to be sharpened after processing a certain number of workpieces. The tool thickness will gradually become thinner, so it is necessary to constantly adjust the tool position. At the same time, due to the change of different workpieces or fixtures, the tooth position of the workpiece will change, and the tool position adjustment also needs to be performed. The tool position adjustment method of gear shaping machines at home and abroad mostly adopts manual adjustment, which is very troublesome to operate.

[0003] In this regard, Chinese patent announcement number CN219324840U discloses "a structure for automatically adjusting the tool position of a gear shaping machine, in which a clutch is arranged on the ball head of the ball tie rod of a conventional gear shaping machine, and the clutch is pushed by hydraulic oil entering the ball head to engage the clutch with the ball head seat, and then the motor for the tooth movement of the tool shaft drives the tool shaft to rotate, driving the ball head seat to rotate, and the ball tie rod shaft to rotate through the clutch, and finally the tool shaft is moved up and down, thereby realizing automatic adjustment of the tool position."

[0004] The above patent ensures that the ball head and the ball head seat are locked or disengaged through the clutch assembly by installing an integrated clutch assembly inside the ball head. When the two are locked, the motor that drives the cutter shaft to rotate with the help of the cutter shaft tooth movement drives the ball head seat to rotate. Among them, there are many components inside the clutch assembly and the entire structure is complex. Once a component fails, the maintenance process is very troublesome. In view of this, the utility model proposes an automatic tool position adjustment structure for a gear shaping machine for reducer production. Utility Model Content

The gear shaping cutter 5 includes a telescopic shaft 51, which passes through the movable seat 3 and is rotatably connected to the movable seat 3.
