Problems solved by technology

[0002] The main processing methods of gears are hobbing, milling, and slotting. The traditional processing method of internal teeth is gear shaping. The gears processed by the slotting processing method have high precision, which can reach 6-7 grades. , the efficiency of slotting processing is low; while the processing efficiency of milling processing method is 4-5 times higher than that of slotting processing method, but the precision of gears processed by milling processing method is low, generally lower than level 9 precision
In addition, the general gear milling machine uses one kind of milling head when milling internal teeth, and another kind of milling head when milling external teeth. When converting internal and external teeth, the milling head must be replaced. Head needs to consume a certain amount of working time, reducing work efficiency

Embodiment

[0011] Example: Place the workpiece on the worktable 6, open the driving device and corresponding control system of the equipment, and drive the shaft 14

[0012] Drive the transmission gear system 15 in the rotary milling head 11 to make the milling cutter 8 work. After reaching the preset processing value, the workpiece is moved to the gear shaper tool holder 7 side through the worktable 6, and the gear shape is performed by the inserting tool 9. So as to complete the gear processing.

[0013] If it is necessary to mill the external teeth, loosen the bolt 12 connecting the ram 16 and the rotary milling head 11, rotate the rotary milling head 11 by 180 degrees, and then fix the bolt 12. At this time, the gear milling machine is in the state of milling the external teeth, so that The gear milling machine does not need to replace the milling head when milling internal and external teeth.

Abstract

The invention discloses a digital control milling and interposing compound machine tool and gear processing method that belongs to gear processing device. It includes column that has crossbeam, and bed on which has workbench base. Workbench is set on the workbench base, and milling teeth blade adapter, on front of which is milling cutter, and interposing teeth blade adapter, on the front of which is slotting tool, are set on the crossbeam. The invention achieves the request of high efficiency and high accuracy to machine gear.

Description

Technical field [0001] The invention relates to a machine tool inserted for processing gears, in particular to a numerical control compound processing machine tool with both pin milling and slotting functions. Background technique [0002] Gear processing methods are mainly hobbing, milling, and inserting. The traditional processing method of internal teeth is gear shaping. The gears processed by the slotting method have high precision, reaching 6-7 levels, but the gears larger than 10 mm are processed in the slotting process. At the same time, the slotting processing efficiency is low; and the processing efficiency of the milling processing method is 4-5 times higher than that of the slotting processing method, but the precision of the gears processed by the milling processing method is lower, generally lower than the level 9 accuracy. In addition, general gear milling machines use one type of milling head when milling internal teeth, and another type of milling head when millin...
