Machining Aids for Turning Slender Shafts

Abstract

The invention discloses a machining auxiliary device for turning of an elongated shaft. The device comprises a connection flange fixed with a spindle chuck through a connection bolt. One end of a limiting pipe is assembled into an assembly inner hole of the connection bolt and fastened through a locking jackscrew. The other end of the limiting pipe is sequentially provided with an adjusting bolt, a locking nut and a gasket. An outer circle of the limiting pipe is sleeved with an auxiliary support body. The machining auxiliary device for turning of the elongated shaft has following beneficial effects: the machining auxiliary device is simple in structure and used conveniently and suitable for turning of elongated shaft-like parts in the machinery field; the limiting pipe controls the whipping amount of an elongated shaft workpiece; the auxiliary support body is used for supporting the limiting pipe while reducing the whipping amount of the limiting pipe and the elongated shaft workpiece during high-speed rotation, thereby avoiding vibration of the front end of the elongated shaft workpiece such that machining precision of a three-jaw clamping part at the front end is ensured; the adjusting bolt is capable of adjusting axial positioning of the elongated shaft workpiece and controlling the length after the elongated shaft workpiece is machined; the locking nut is capable of locking the adjusting nut so that length uniformity of the elongated shaft workpiece after machining is ensured.

Description

technical field [0001] The invention belongs to an auxiliary processing device, in particular to a processing auxiliary device for turning a slender shaft. Background technique [0002] In the machining industry, when one end of the slender shaft is machined during high-speed rotation, since the part of the slender shaft placed in the hollow hole of the main shaft of the lathe has no auxiliary support, it will cause a large amount of swing, resulting in vibration of the clamping part of the front end, affecting Its machining accuracy. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings in the prior art, and its purpose is to provide a processing aid for turning slender shafts. [0004] Technical scheme of the present invention is: [0005] A processing aid for turning a slender shaft, including a connecting flange fixed to a spindle chuck through connecting bolts; one end of a limit tube is fitted into the assembly i...
