Description
Technical field
The utility model relates to pencil sharper pointed collar domains, the in particular to removable pencil sharper sharp knife of toothholder.
Background technique
Pencil sharper sharp knife is the tool for cutting pencil, and effect is for the head that sharpens the point of a pencil, and existing pencil sharper sharp knife is logical
There are two types of often, one is abrasive band is mounted on disk, rotating circular disc, by the abrasive band sharpening tip of the brushstyle of a writing or painting, the big noise of gray tip in production
It rings and processing quality is poor, the color of lead stamen can adhere on abrasive band and penholder, and second is to be provided with alloy blade on disk, still
Blade is easy to happen damage to this sharpening knife during the work time, once and breaks down will affect and cut effect, need whole
The problem of body replacement, the processing service life is shorter, and the above problem is this field urgent need to resolve.
Utility model content
The technical issues of the utility model solves is to provide a kind of removable pencil sharper sharp knife of the toothholder that toothholder is replaceable.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the removable pencil sharper sharp knife of toothholder, including
Cutter hub and toothholder are connected with cutter tooth on the toothholder, and the cutter hub is circular drum, are provided on the cutter hub several in multiple rows of
The positioning groove of helical alignment is provided with mounting hole in the positioning groove, and the toothholder includes that mounting portion is connected with cutter tooth
The shape in portion, the mounting portion is consistent with positioning groove shape, and fixation hole corresponding with mounting hole is provided on the mounting portion.
The application is detachably arranged in fixing groove by the way that locating slot and mounting hole, toothholder are arranged on cutter hub, thus
Toothholder in the application is replaced, the processing service life is improved.
Further, the mounting portion is screwed in positioning groove.
Further, the cutter hub material is aluminium.
Further, the cutter tooth is diamond sheet body, cutter tooth is set to cutter tooth interconnecting piece end by welding.
Further, the angle of tip to the circle center line connecting of the cutter tooth front and cutter tooth is -25 ° to 50 °.
Further, the back side is inclined-plane behind the end of the cutter tooth, the rear back side and cutter tooth tip to circle center line connecting
The angle of vertical line be 5 ° to 60 °.
Further, the angle of the positive horizontal plane of cutter tooth and cutter hub axial direction horizontal center line is 0 ° to 70 °.
Further, the width range of the cutter tooth is 5mm to 80mm.
The beneficial effects of the utility model are: improving the processing service life, cutter hub is aluminium by being provided with dismountable toothholder
Cutter hub processed, so that the application weight is lighter, generated noise is smaller in process, and cutter tooth is that diamond sheet body makes this Shen
It is please more durable.
Detailed description of the invention
Fig. 1 is the overall schematic of the application.
Fig. 2 is cutter hub schematic diagram.
Fig. 3 is toothholder schematic diagram.
Fig. 4 is cutter tooth side view.
Fig. 5 is cutter tooth top view.
In the figure, it is marked as cutter hub 1, positioning groove 11, threaded hole 12, toothholder 2, cutter tooth interconnecting piece 22, mounting portion 23, cutter tooth
3, screw 4.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1 to Figure 3, the removable pencil sharper sharp knife of toothholder, including cutter hub 1 and toothholder 2, wherein toothholder 2 includes peace
Dress portion 23 and cutter tooth interconnecting piece 22, cutter tooth 3 are set to 22 end of cutter tooth interconnecting piece by welding, and the cutter tooth 3 is preferably Buddha's warrior attendant
Flag body may be alternatively provided as metal sheet, and the cutter hub 1 is the circular drum of aluminum, be provided on the cutter hub 1 several in more
The positioning groove 11 of helical alignment, the positioning groove 11 generally rectangle are arranged, groove quadrangle is provided in round, the toothholder
The shape of mounting portion 23 on 2 is consistent with 11 shape of positioning groove, and threaded hole 12, institute are provided in the middle part of the positioning groove 11
It states and is provided with counterbore corresponding with threaded hole 12 or through-hole on mounting portion 23, spiral shell is inserted into the counterbore or through-hole of the mounting portion 23
Silk 4, screw 4 is threadedly coupled with threaded hole 12, so that toothholder 2 is fixed in positioning groove 11.
As shown in Figure 1 to Figure 3, since the application is provided with positioning groove 11 on cutter hub 1, by positioning groove 11 by tooth
Seat 2 is fixed on cutter hub 1, and the positioning groove 11 is used to position toothholder 2, so that toothholder 2 will not shake at work,
Positioning groove 11 is arranged using multi-detector formula, so that it is more smooth when closely cutting, simultaneously because positioning groove 11 and tooth
Seat 2 is connected by screw 4, when occurring when there is the damage of cutter tooth 3 the case where, it is only necessary to single toothholder 2 is dismantled and replaces,
Without integral replacing cutter hub 1, use cost greatly reduces, improves the processing service life, while cutter tooth 3 is made of stones using Buddha's warrior attendant
At further increasing the processing service life, and cutter hub 1 is adopted and is formed from aluminium so that the application weight is lighter, is issued in process
Noise is smaller.
As shown in Figure 4 and Figure 5, on the basis of the above, cutter tooth 3 is preferably configured by following parameter, the front of cutter tooth 3 with
