Abstract

The utility model discloses a cutting cutterhead for machining an ultra-slender shaft. The cutting cutterhead for machining the ultra-slender shaft comprises a bearing pedestal, a cutterhead shell, cutters, a tensioning sleeve and a guide sleeve, wherein the cutterhead shell is arranged on a bearing of the bearing pedestal; the cutters are fixed on a tool apron on the end surface of one side of the cutterhead shell, and the end surface of the other side of the cutterhead shell is connected with a spindle of a lathe through a bolt and a flange; the tensioning sleeve is fixed on the bearing pedestal through a fixing pin, and is radially provided with pressure springs, and heads of the pressure springs are connected with steel balls and point to the axle center of the tensioning sleeve; and the guide sleeve is fixed on the end surface of one side, which is far away from the cutters, of the tensioning sleeve through bolts. The utility model has the advantages that 1) the cutting cutterhead has a simple structure, is convenient to manufacture, and is low in equipment cost; 2) the double cutters are used for cutting, the cutting forces are mutually offset, and the cutters are stable during cutting, so the machining quality of workpieces is ensured; and 3) the cutters do rotary motion, the workpices do feed movement, and the cutting is similar to thread whirling, so that the machining efficiency is high.

Description

The Cutting tool of processing superfine major axis

Technical field

The utility model relates to a kind of Cutting tool of processing superfine major axis.

Background technology

In turning processing, processing slim axle and superfine shaft be a technical barrier often, generally all adopts workpiece rotates, cutter is done feed motion method to finish the processing of slender axles; Processing request according to slender axles, do not surpassing in the machine tool guideway travel range, normal follow-rest or the centre frame of adopting supports, with the rigidity of raising slender axles, but in process, because the one-side cutting force of cutter, can force that slender axles shake owing to sending out appears in the reasons such as effect, thermal deformation and deadweight of cutting force, crooked, distortion, the slender axles long for length, that required precision is high also difficulty reach requirement, even if reach requirement, working (machining) efficiency is also lower; If surpass the slender axles of machine tool guideway travel range, then generally be that replacing or the lathe that adds long guideway customized are processed, this certainly will increase cost again.

Summary of the invention

The utility model for shake owing to sending out appears in the reasons such as effect, thermal deformation and deadweight of cutting force in present slender axles and the superfine shaft process, the problem of crooked, distortion, the Cutting tool of the processing superfine major axis that a kind of working (machining) efficiency is high, machining accuracy is high has been proposed.

The Cutting tool of processing superfine major axis described in the utility model is characterized in that: comprise bearing block, cutterhead shell, cutter, tensioning sleeve, fairlead, described cutterhead shell is installed on the bearing of described bearing block; Fixed cutting tool on the tool rest of one side end face of described cutterhead shell, the opposite side end face is connected with the main shaft of lathe by ring flange by bolt; Described tensioning sleeve is fixed on the described bearing block by steady pin, and described tensioning sleeve radially arranges stage clip, and the head of described stage clip connects steel ball, points to the axle center of described tensioning sleeve; Described fairlead is bolted on the end face away from cutter one side of described tensioning sleeve.

Described cutterhead shell is assemblied on the described bearing block by two single-row radial ball bearings.

Described fairlead is coaxial with described tensioning sleeve.

Four groups of stage clips are set in the described tensioning sleeve, and described stage clip is symmetrical in twos, realizes the self-centering of workpiece.

Described cutterhead shell is installed two width of cloth cutters.

The Cutting tool of described processing superfine major axis can be applicable on the lathe, is preferably applied to the C6140 lathe.

During work, after the end to be cut of workpiece inserted from fairlead, self-centering was realized on the surface of the steel ball contact workpiece of stage clip head, the position of then adjusting cutter, and cutter rotatablely moves, and workpiece realizes that by fairlead and tensioning sleeve feed motion realizes turning.

The beneficial effects of the utility model are: 1) simple in structure, easily manufactured, equipment cost is low; 2) because double-pole cuts, the cutting force of just in time cancelling out each other is stablized during cutting, is conducive to guarantee the crudy of workpiece; 3) cutter rotates, and workpiece is done feed motion, similar whirling, and working (machining) efficiency is high.
