Preferably, described drive shaft one end is provided with detent mechanism, and this detent mechanism is adjacent to blade side；Drive shaft The other end forms screw thread, and nut by blade positioning on the driving shaft, and is provided with pad between nut and blade.

This utility model highlights and useful having the technical effect that compared to existing technology

1, cutter head width of the present utility model is more than the thickness of blade, and it can be made can to avoid in actual use Gap occurs, it is ensured that handled impurity can uniformly be dispelled.

2, staggered on the driving shaft with 45 ° or 60 ° or 90 ° of angles between adjacent two blades of this utility model, different In unidirectional array of the prior art, can directly form channel of chip removal, improve chip removal ability.And staggered mode can So that plane wall telephone each moment only one of which insert contacts metope in actual use, each cutter head cuts wall successively Wall, it is not necessary to simultaneously cut so that cutter head incision strength can concentrate on each cutter head, it is easy to incision wall, is difficult to card Live.

3, the edge of a knife line of cutter head of the present utility model and the axis of drive shaft have one 5 °～the inclination angle of 20 °, so Design can allow plane wall telephone in use, single cutter head is first to contact metope with an angle, and strength all concentrates on one On individual point, it is easy to incision wall, increase service efficiency.

4, blade both sides of the present utility model outwardly convex respectively, makes directly to be formed between each two blade chip area, no Need separately to interspace, increase chip removal ability, it is also possible to make structure more stable.

5, blade of the present utility model is connected in the way of flat key is connected with drive shaft, it is possible to be securely fixed in by blade In drive shaft, make plane wall telephone in use will not loosen, preferably power is acted on metope, strengthen plane wall effect.

6, blade of the present utility model is each independent, and during use, cutter head blunt or damage can single disassemble, It is conveniently replaceable.

Detailed description of the invention

With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings:

As shown in Figures 1 to 3, the rotor of this utility model plane wall telephone includes hobboing cutter assembly 1 and drive shaft 2, and hobboing cutter assembly 1 wraps Including several blades 3, blade 3 includes matrix 4 and cutter head 5, and the width of cutter head 5 is more than the width of matrix 4；Blade 3 is the most axial Staggered on driving shaft 2；Axial chip area 6a is formed between the cutter head 5 of adjacent two blades 3；45 °≤adjacent two cuttves Corner≤90 ° between sheet 3.In the present embodiment, the corner between adjacent two blades 3 is 90 ° so that plane wall telephone is using During, the chip scaled off can directly be dropped in chip area 6a, will not stop the motion of cutter head 5.

As in figure 2 it is shown, be provided with two cutter heads 5 on the matrix 4 of blade 3, two cutter heads 5 are separately positioned on the phase of matrix 4 Offside；The edge of a knife line of cutter head 5 and the axis of drive shaft have an inclination angle, and this inclination angle typically takes 5 °～20 °, during use, Can make cutter head 5 corner a little first contact metope, all impose on this some incision wall, by straight line locally by strong for institute Contact changes point cantact into, reduces the contact area of unit interval, it is easy to cutting；In the present embodiment, cutter head 5 is fixing with matrix 4 Connected mode is welding, i.e. cutter head 5 is welded on matrix 4, makes cutter head 5 be securely attached on the matrix 4 of blade 3, it is to avoid make During with, cutter head 5 drops, and increases the service life.

The both sides of blade 3 outwardly convex respectively, defines radially chip area between two blades 3 adjacent in the present embodiment 6b, expands the scope of chip area, thus strengthens chip removal ability.

In the present embodiment, as a kind of scheme, matrix 4 center forms a circular hole 7 and more than one keyway One 8a, the keyway one 8a position of each blade 3 is depending on blade 3 position on driving shaft 2；Drive shaft 2 forms one along axle Individual above keyway two 8b, each blade 3 passes sequentially through key 9 and connects on driving shaft 2；Alternatively, with drive shaft 2 For key, by direct for blade 3 clamping on driving shaft 2.Such connected mode can facilitate independent disassembling blade 3, it is simple to blade 3 Change.

Drive shaft 2 one end is provided with detent mechanism 10, and this detent mechanism is adjacent to blade side；Drive shaft 2 other end becomes Type has screw thread, nut 11 to be positioned on the driving shaft by blade 3, and is provided with pad 12 between nut 11 and blade 3.

This utility model simple in construction, forms multiple chip area, is greatly enhanced the chip removal ability of plane wall telephone, extends and uses the longevity Life, digging wall during use does not has gap, effective, and being connected firmly of blade and drive shaft is simple, it is possible to increase transmission efficiency and Rotor stress balance operationally, improves operation comfort, it is easy to dismounting, easy to use.
