Description
Technical field
The invention belongs to process tool technical fields, are related to a kind of hobboing cutter, in particular to a kind of spling hob.
Background technique
Rectangle splined spindle is a kind of machine components that application is very wide, is mainly used in aircraft, automobile, tractor, lathe system
It makes in the mechanical driving devices such as industry, agricultural machinery, plays a part of to transmit mechanical torque, rectangle splined spindle generallys use milling cutter to mill
(forming process) and (method of development) two kinds of processing methods are rolled with hobboing cutter.Gear Milling production efficiency is low, at high cost, is suitable for single-piece
Processing, gear hobbing process high production efficiency, single products are at low cost, are suitable for batch production.For processing rectangle on existing market
The hobbing method for processing of splined shaft can form easement curve in workpiece tooth root, sometimes also very big.And certain occasions, splined shaft tooth root
It is not allow for easement curve, is also not allow for sinking cutting, conventional Rectangular Spline Hob is often difficult to meet this requirement.
Summary of the invention
The purpose of the present invention is being directed to the above-mentioned problems in the prior art, easement curve can be reduced by providing one kind
And spling hob high-efficient, that precision is good.
Object of the invention can be realized by the following technical scheme: spling hob, including cutter hub, the center of the cutter hub
Position is provided with axis hole, and multiple cutting tooths are evenly arranged on the periphery wall of the cutter hub, which is characterized in that described adjacent two
It is provided with chip removal tooth socket between a cutting tooth, the cutting tooth includes several hob teeths and two circle-arc teeth, and described two
It is provided with top sword at the top of circle-arc tooth, and two circle-arc teeth are along the center that cutter hub is axially set in cutter hub periphery wall, Ruo Gansuo
The hob teeth stated is set to the outside of circle-arc tooth, and divides equally to arrange along axis and extend to cutter hub outer end face, the chip removal tooth socket
Width is 3 millimeters, and is provided with chamfering at the top of chip removal tooth socket with the cutting tooth tail portion place of connecting, and chamfering angle with horizontal plane is in 30
Degree.
Technical effect of the invention: it before processing workpiece with spling hob, accurately to carry out guaranteeing spline rolling to knife
Knife and workpiece strictly keep correct relative position, keep circular arc tooth top sword circular arc and workpiece concentric, when processing, the two sides tooth of workpiece
Face be transformed by hob profile, and the tooth root of workpiece be milled out by circle-arc tooth on hobboing cutter Lai.Not only keep gear hobbing working efficiency
Advantage high, with high accuracy, this splined shaft of no easement curve can not be processed by also solving the problems, such as its a little producer at all.
In above-mentioned spling hob, the top sword circular arc of described two circle-arc teeth is symmetrical arranged.
In above-mentioned spling hob, the radian of two circle-arc teeth be on the basis of two circle-arc tooth center lines, away from
Circle-arc tooth inside pitch line length is that the center of circle is determined at 18.6 millimeters, is 16 millimeters with radius and carries out cutting resulting radian i.e. to circle-arc tooth
For the radian value of circular arc tooth top sword.
In above-mentioned spling hob, the circular arc of the top sword is annular in shape.
In above-mentioned spling hob, the facewidth of the cutting tooth is 5.7 millimeters.
Compared with prior art, this Rectangular Spline Hob solves spline using by method of the hob teeth in conjunction with circle-arc tooth
There is transition wire in axis tooth root, while having the advantages that work efficiency is high, with high accuracy.
Detailed description of the invention
Fig. 1 is the general structure schematic diagram of this spling hob.
Fig. 2 is the local structural graph of the cutting tooth tooth form of this spling hob.
In figure, 1, cutter hub；2, axis hole；3, cutting tooth；4, chip removal tooth socket；5, hob teeth；6, circle-arc tooth；7, sword is pushed up.
Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figure 1, 2, this spling hob, including cutter hub 1, the centre of cutter hub 1 are provided with axis hole 2, the periphery of cutter hub 1
It is evenly arranged with multiple cutting tooths 3 on wall, chip removal tooth socket 4 is provided between two neighboring cutting tooth 3, cutting tooth 3 includes several
Hob teeth 5 and two circle-arc teeth 6, are provided with top sword 7 at the top of two circle-arc teeth 6, and two circle-arc teeth 6 are set along cutter hub 1 is axial
It is placed at the center of 1 periphery wall of cutter hub, several hob teeths 5 are set to the outside of circle-arc tooth 6, and divide equally to arrange along axis and extend to
The height of 1 outer end face of cutter hub, each hob teeth 5 is unequal, and the cutter tooth of two sides wants higher, so as to by the straight line tooth form one of splined shaft
Vertical cut is round to root, and the cutter tooth at intermediate position wants shorter, makes not cut in the root circle of workpiece, and the hob teeth 5 of right end processes work
The left side of part, i.e., on the right side of the upper tooth socket of root circle, the right side of the 5 workpieces processing tooth form of hob teeth of left end, i.e. root knuckle-tooth slot
