Indexing positioning right-angle milling head

Abstract

The invention relates to the technical field of metal milling devices, and discloses an indexing positioning right-angle milling head. The milling head comprises a shell, a vertical shaft, a bevel gear unit connected with the vertical shaft, a horizontal shaft which is connected with the bevel gear unit and is vertical to the vertical shaft, a vertical shaft lifting device and a vertical shaft bearing seat tightening device, wherein a vertical shaft bearing seat can rotate in a vertical shaft shell; and by the vertical shaft bearing seat tightening device, the horizontal shaft in the shell, a shaft element of the horizontal shaft and the vertical shaft bearing seat are driven to rotate through a horizontal shaft shell by taking the vertical shaft as an axis. The milling head has the advantages of high indexing accuracy of a right-angle milling head, accurate indexing accuracy, time saving and labor saving in the indexing process, high equipment rigidity and the like.

Description

technical field [0001] The invention relates to the technical field of metal milling devices, in particular to an indexing and positioning right-angle milling head. Background technique [0002] The right-angle milling head in the prior art is an accessory that uses a pair of bevel gear sets that mesh with each other to convert the vertical axis perpendicular to the table into a horizontal axis parallel to the table; the housing of the old-fashioned right-angle milling head structure is a The monolithic structure has the advantages of simple manufacture, low cost and good rigidity. However, its disadvantage is that the indexing angle efficiency is extremely low, which greatly reduces the processing efficiency of the machine tool. Chinese patent literature (publication number CN 101100035A) discloses a "bevel gear right-angle milling head", which converts the vertical rotation of the CNC machine tool spindle into the horizontal rotation of the milling head through a pair of...

Problems solved by technology

At present, there is a method to directly rely on the key block to transmit the torque, but the poor alignment of the key block will also generate radial force, which will cause the key block to wear out sharply, and lose the pulling force of the main shaft broach, and the actual use effect is not good.

[0003] Therefore, the right-angle milling head in the prior art has the disadvantages of low indexing efficiency, low indexing accuracy, poor shell rigidity, and large manpower required for turning corners.

In addition, there are problems such as poor working environment of the bearing, unstable transmission, short service life, and low processing efficiency due to the coaxiality error between the rotating shaft and the machine tool spindle.
