Abstract
The utility model provides a facer, and belongs to the technical field of machining tools. The problem that a conventional facer is low in machining efficiency and poor in structural stability is solved. The facer comprises a cutter body, wherein a plurality of blade fixing parts which are uniformly distributed are arranged at the front end of the cutter body; blade installation grooves used for installing blades are formed in the blade fixing parts; shapes of the blade installation grooves are matched with those of the blades; each blade installation groove comprises two crossed side walls and one bottom surface; one side wall is attached to one side surface of the blade, and the other side wall is attached to the other side surface of the blade; fixing bolts which are used for fixing the blades on the blade installation grooves are also arranged on the blade installation grooves; and each bolt is arranged obliquely towards a joint of the two side walls. The facer has the advantages as follows: the machining efficiency is high, the cutting is performed nimbly, the machining accuracy is high, and the like.
Description
Technical field
The utility model belongs to the cutting-tool engineering field, relates to a kind of facing cutter, particularly a kind of positive angle blade facing cutter.
Background technology
Traditional facing cutter, mainly comprise cutter hub and be located at the blade installation slot that the cutter hub periphery evenly arranges, and in this blade installation slot, has been bolted blade.When blade is installed, need manually the blade of installation is proofreaded one by one, the tool setting time is long, and error is large, and when lathe power is little, rigidity is when poor, stock-removing efficiency is low, and blade can not be brought into play maximum cutting advantage.Blade well can not be fixed in mounting groove by single bolt, add man-hour, the position of blade changes slightly, affects machining accuracy.
The positive angle blade is a kind of of blade, its shape is quadrangle, and while being installed on facing cutter by the positive angle blade, the positive angle blade all is perpendicular to surface to be machined, needs enough large cutting force, difficult workpiece is carried out to smear metal, and stock-removing efficiency is low, and cutting precision is low.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, proposed a kind of structural stability high, the cutting great efforts facing cutter.
The purpose of this utility model can realize by following technical proposal:
A kind of facing cutter, comprise cutter hub, the front end of described cutter hub has some equally distributed blade fixed parts, it is characterized in that, on described blade fixed part, have for the blade installation slot of blade is installed, the shape of described blade installation slot and the shape of blade are complementary, described blade installation slot consists of two crossing sidewalls and a bottom surface, a side of one of them described sidewall and blade fits, another side of another described sidewall and blade fits, on described blade installation slot, also be provided with for blade being fixed on to the set bolt on this blade installation slot, described bolt is obliquely installed to the intersection of two side.
After installing, two crossing sidewalls and bottom surface blade are carried out spacing, and then by a bolt, blade are fixed in blade installation slot, make the stability of blade higher, add the man-hour position and can not be offset, and have improved machining accuracy.By the tilt bolt setting, but blade pushed, the side of blade and sidewall are fitted tightly, increase friction, improve stability.
In above-mentioned a kind of facing cutter, described blade is obliquely installed, and the angle that the axis of described blade and cutter hub is is 10 ° to 30 °.Blade with by the angle of smear metal workpiece, be acute angle, facilitate the processing of blade, and need very little cutting force just workpiece to be cut, cut briskly, improved stock-removing efficiency.
In above-mentioned a kind of facing cutter, the angle that the axis of described blade and cutter hub is is 20 °.
In above-mentioned a kind of facing cutter, described blade fixed part is 4-6.
In above-mentioned a kind of facing cutter, described blade fixed part is 5.
Compared with prior art, this facing cutter has the following advantages:
Two sidewall blade by blade installation slot are carried out spacing, apply extruding force by the bolt blade be obliquely installed, two sides of blade are fitted respectively, increasing friction force with two sidewalls of blade installation slot, improve the stability of blade, thereby improve machining accuracy; And by the setting in a certain angle of the axis of blade and cutter hub, facilitate the cutting of blade, cut brisk, stock-removing efficiency is high.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
In figure, 1, cutter hub; 2, blade fixed part; 31, sidewall; 32, bottom surface; 4, bolt; 5, blade.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Facing cutter as shown in Figure 1, comprise cutter hub 1, and the front end of cutter hub 1 has some equally distributed blade fixed parts 2, and in actual use, quantity that can blade fixed part 2 is set to 4-6, and in the present embodiment, the quantity of blade fixed part 2 is 5.
As shown in Figure 1, on blade fixed part 2, have for the blade installation slot of blade 5 is installed, the shape of the shape of blade installation slot and blade 5 is complementary, as shown in Figure 1, blade installation slot consists of two crossing sidewalls 31 and a bottom surface 32, one of them described sidewall 31 fits with a side of blade 5, another sidewall 31 fits with another side of blade 5, on blade installation slot, also be provided with for blade 5 being fixed on to the set bolt 4 on this blade installation slot, bolt 4 is obliquely installed to 31 intersection, two side.
After installing, two crossing sidewalls 31 and bottom surface 32 blade 5 are carried out spacing, and then by a bolt 4, blade 5 are fixed in blade installation slot, make the stability of blade 5 higher, add the man-hour position and can not be offset, and have improved machining accuracy.Bolt 4 is obliquely installed, but blade 5 pushed, the side of blade 5 and sidewall 31 are fitted tightly, increase friction, improve stability.
In order to increase the cutting dynamics, the angle that the axis of blade 5 and cutter hub 1 is is 10 ° to 30 °, blade 5 with by the angle of smear metal workpiece, be acute angle, facilitate the processing of blade 5, and need very little cutting force just workpiece to be cut, and cut briskly, improved stock-removing efficiency.
In the present embodiment, as shown in Figure 1, the angle that the axis of blade 5 and cutter hub 1 is is 20 °.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
