Connecting device of milling cutter

Abstract

The invention discloses a connecting device of a milling cutter. The connecting device is characterized by comprising a main shaft, a driven shaft and a box; the main shaft is horizontally coupled into the box; the driven shaft is vertically coupled into the box; the front end of the main shaft is coaxially fixed with a driving bevel gear; the driven shaft is coaxially fixed with a driven bevel gear; the driven bevel gear is engaged with the driving bevel gear; the milling cutter is fixedly mounted at the lower end of the driven shaft; and the back end of the main shaft is coaxially and fixedly connected with an output shaft of a motor or a main shaft of a machine tool through a coupling. The connecting device of the milling cutter has the following advantages: as the milling cutter is fixed on the connecting device, the vertical machining in large-travel and small-diameter workpieces can be realized, such as inner-diameter oil groove machining of workpieces and inner-diameter key slot finishing; the connecting device is high in machining precision, relatively small in size and light in weight; and the back end of the main shaft can be coaxially and fixedly connected with the output shaft of the motor or the main shaft of the machine tool through the coupling, so that the multi-stand common use can be realized, and the application range is wide.

Description

technical field [0001] The invention relates to a connection structure between a milling cutter and a machine tool, in particular to a connection device for a milling cutter. Background technique [0002] At present, for the internal processing of small-diameter workpieces (including keyways, inner holes, etc.), many slotting machines are used for processing. Although they can reach the required size, the processing efficiency is low, the finish is poor, and the processing is difficult; some are processed by universal small milling machines. , but due to the limitation of the milling method, it cannot be processed to the required size; some of them use manual grinding, which is extremely inefficient and uneven. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a connection device for milling cutters that can be used for internal processing of workpieces with small diameters and has high processing accuracy.
