Mandrel automatic gear hobbing device

Abstract

The invention relates to the field of machining, and provides a mandrel automatic hobbing device. The mandrel automatic hobbing device comprises a loading device and a hobbing device; the hobbing device includes a hobbing base, and an oil pressure chuck, a thimble and a hobbing tool connected to the hobbing base; the oil pressure chuck and the thimble are coaxially arranged for clamping the mandrel; the axles of the oil pressure chuck and the thimble are clamping axles; the loading device includes a loading device body detachably connected to the hobbing device, and a discharge mechanism, a material preparation mechanism and a loading mechanism arranged on the loading device body; the discharge mechanism includes a storage bin, a discharge bin, a discharge cylinder and a discharge movable plate; the material preparation mechanism includes a first material preparation area, a second material preparation area, a material preparation cylinder and a material preparation baffle plate; and the loading mechanism includes a transverse loading mechanism, a longitudinal loading mechanism and a material clamping part. The mandrel automatic hobbing device can efficiently load materials, and is high in precision, excellent in stability and high in generality.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an automatic gear hobbing device. Background technique [0002] In the prior art, some mandrel gear hobbing devices are manually loaded, and the degree of automation is not high, which affects the efficiency of the mandrel hobbing process. In addition, in the prior art, there is also a device that can realize automatic feeding, but because the gear hobbing cutter exerts a large force on the mandrel during the gear hobbing operation, the gear hobbing device must perform reliable and efficient feeding on the mandrel. Clamping, and the automatic feeding mechanism in the prior art, due to the insufficient control accuracy of the feeding position, it is easy to cause the hobbing device to clamp the mandrel not firmly, or to use a more complicated structure to clamp firmly Hold the mandrel. In addition, the automatic feeding device for the mandrel in the prior art adopts rigid fe...

[0002] In the prior art, some mandrel gear hobbing devices are manually loaded, and the degree of automation is not high, which affects the efficiency of the mandrel hobbing process

In addition, in the prior art, there is also a device that can realize automatic feeding, but because the gear hobbing cutter exerts a large force on the mandrel during the gear hobbing operation, the gear hobbing device must perform reliable and efficient feeding on the mandrel. Clamping, and the automatic feeding mechanism in the prior art, due to the insufficient control accuracy of the feeding position, it is easy to cause the hobbing device to clamp the mandrel not firmly, or to use a more complicated structure to clamp firmly Holding mandrel

In addition, the automatic mandrel feeding device in the prior art adopts rigid feeding. If the accuracy is not enough, it is easy to cause wear of the material and chuck, and may even lead to feeding failure.

Furthermore, the feeding efficiency of the automatic mandrel feeding device in the prior art is also low, which cannot meet the needs of efficient feeding in automated production
