Stepped shaft outer circle surface milling keyway apparatus

Abstract

The invention discloses a stepped shaft outer circle surface milling keyway apparatus, which comprises a base, wherein the base is provided with a moving seat capable of horizontally moving left and right, the moving seat is oppositely provided with a left ejection tip support seat and a right ejection tip support seat, the left ejection tip support seat is provided with a left ejection tip, the right ejection tip support seat is provided with a right ejection tip, the center axis of the left ejection tip coincides with the center axis of the right ejection tip, a stepped shaft is arranged between the left ejection tip and the right ejection tip, hydraulic moving claws are uniformly distributed on the right ejection tip support seat along the radial direction of the right ejection tip, thehydraulic moving claw at least has two out surfaces capable of simultaneously grasping the end portion of the stepped shaft, the base is provided with a cutter support seat, the cutter support seat is provided with a cutter installing seat, the cutter installing seat can vertically move up and down, and is vertically provided with a milling cutter, and the milling cutter rotatablely move down, and is matched with the moving seat to mill to form a keyway. According to the present invention, the positioning clamping mode of the stepped shaft outer circle surface milling keyway apparatus is simple, and the keyway milling precision is high.

Description

technical field [0001] The invention relates to an improvement of a processing device for key grooves on the outer circular surface of shaft parts, in particular to a device with simple positioning and clamping, high milling precision of key grooves, and detection of whether the size of key grooves meets the requirements and the center lines of multiple key grooves. Whether it is overlapped or not, the stepped shaft outer circle milling keyway device with fast detection speed. Background technique [0002] In the prior art, when milling the keyway on the outer surface of the shaft part, the shaft part is generally fixed by combining the three-jaw chuck with the top, and then the required keyway is milled out with a milling cutter; however, the three-jaw chuck is used to fix the shaft For such parts, once the surface of the shaft part is rough and uneven, the axis of the three-jaw chuck cannot coincide with the central axis of the shaft part, thus affecting the accuracy of ke...
