Embodiment Construction

[0024] see figure 1 , figure 2 , a 180° two-way differential milling head, comprising a milling cutter housing, an outer housing, and a connecting housing arranged between the milling cutter housing and the outer housing, the milling cutter housing is connected to the connecting housing through the housing end cover The body and the outer shell are fixed by bolts. The milling cutter housing is in the shape of a straight cylinder, and the milling cutter housing is provided with a C-axis drive spindle in the axial direction. The input end of the C-axis drive spindle extends outward from the milling cutter housing and connects to the handle. The handle is 2BT40 handle. The output end of the C-axis transmission main shaft is supported on the connection housing through bearings. One side of the milling cutter housing is fixed with a positioning pin housing, and a positioning pin is slid in the axial direction of the positioning pin housing, and an organic rice screw is threaded...

Abstract

The invention discloses a 180-degree bidirectional differential milling head. The milling head improves the machining efficiency and can complete differential machining according to different machining requirements. The milling head comprises a milling cutter shell, an outer shell and a connecting shell arranged between the milling cutter shell and the outer shell, a C-axis transmission main shaftis arranged in the milling cutter shell, an A-axis driving bevel gear shaft and a B-axis driving bevel gear shaft are fixed to the output end of the C-axis transmission main shaft in the axial direction, and the gear modulus of the B-axis driving bevel gear shaft is smaller than that of the A-axis driving bevel gear shaft. An A-axis driven bevel gear shaft and a B-axis driven bevel gear shaft arecoaxially installed in the outer shell through bearings respectively, the tooth portion of the A-axis driven bevel gear shaft is meshed with the tooth portion of the A-axis driving bevel gear shaft,the tooth portion of the B-axis driven bevel gear shaft is meshed with the tooth portion of the B-axis driving bevel gear shaft, and the shaft portions of the A-axis driven bevel gear shaft and the B-axis driven bevel gear shaft are oppositely arranged, and provided with milling cutter mounting structures respectively.

Description

technical field [0001] The invention relates to the technical field of milling, in particular to a 180° bidirectional differential speed milling head. Background technique [0002] In response to the high-speed and high-precision requirements in the machining process, many milling heads with different structures have appeared, which can not only expand the processing range of the machine tool, but also ensure the processing quality. Among them, the bidirectional output milling head can complete the simultaneous processing of two planes with high requirements for coaxiality or parallelism, but at present, the bidirectional output speed of this kind of milling head is the same, and it cannot achieve efficient processing when processing workpieces with inconsistent surface requirements . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a 180° two-way differential milling head. The present inv...
