Abstract
The utility model discloses a multi-blade heavy boring cutter. A cutter body comprises a cutter head portion and a cutter handle portion, the cutter handle portion is integrally formed with the cutter head portion, the cutter head portion is in a multi-cutting-section type, two blade installation tables are symmetrically distributed on the head portion of each section of the cutting sections, the blades are conveniently installed, and an angle are conveniently positioned. The multi-blade heavy boring cutter overcomes the shortages that the installation angle of the blades is not accurate when the cutter conducts chamfering process, the connection of the blades and grooves is not stable when the blade cuts, and the blades are easy to move in the prior art. The utility model provides the improved boring cutter. The multi-blade heavy boring cutter enables the blades not to move when cuts, guarantees processing speed and processing accuracy, can rapidly position the angle while a chamfering blade is installed, guarantees accuracy of the processed chamfering, improves processing accuracy and saves processing time.
Description
Technical field
The utility model belongs to the cutter of machining, particularly a kind of multiple-cutting-edge heavy boring cutter.
Background technology
Existing boring cutter is processed the boring cutter of multistage multi-tool edge, but every grade of cutting edge is still only installed a slice blade, causes working ability still not too strong, and in working angles, in a single day the cutting edge of boring cutter is subjected to force unbalance, just causes the displacement of blade easily, even fracture; And the hole of processing is when needing different chamfering, and common way is the tool changing tool, and the concave station with boring cutter changed rotary type into afterwards, but the angle adjustment process is loaded down with trivial details, and not necessarily inaccurate, waste process time.
The utility model content
Technical problem to be solved in the utility model provides a kind of multiple-cutting-edge heavy boring cutter, can make boring cutter add the man-hour cutting blade and be fixed well, and can accurately adjust the machining angle of chamfered cutting edge simultaneously.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of multiple-cutting-edge heavy boring cutter, cutter hub comprises one-body molded cutter head portion and handle of a knife portion, described cutter head portion is made of first segment of cutting, second segment of cutting, the 3rd segment of cutting, the 4th segment of cutting and the 5th segment of cutting, described every section segment of cutting head all is symmetrically distributed with two blade erecting beds, described blade erecting bed comprises groove and blade fixed block, blade and blade fixed block are installed on the described groove, are offered the angle marked area between described blade and the blade fixed block.
Further, 3 angles are carved with in described angle marked area, are respectively 30 °, 45 °, 60 °.
Before the processing, earlier successively as required, install cutting blade and chamfered cutting edge and install the blade fixed block, then handle of a knife is connected by bolt with lathe, can process.
Advantage: 1, the blade fixed block is installed on the groove, is made the fixing more stable of blade, can prevent better that blade from may produce the problem of displacement when the chance cutting output is big.2, as the different chamfering of need processing, only need to adjust according to the scale of angle marked area sign the setting angle of blade, improved process velocity and precision.

The specific embodiment
Example one
As Fig. 1, Fig. 2, shown in Fig. 3, the utility model is a kind of multiple-cutting-edge heavy boring cutter, cutter hub comprises one-body molded cutter head portion 1 and handle of a knife portion 2, described cutter head portion 1 is by first segment of cutting 3, second segment of cutting 4, the 3rd segment of cutting 5, the 4th segment of cutting 6 and the 5th segment of cutting 7 constitute, described every section processing sections head all is symmetrically distributed with two blade erecting beds, and (wherein Fig. 1 is simplified painting, though first, second, the 3rd, the 4th, the 5th segment of cutting has all only been drawn a blade, but in every section actual enforcement of segment of cutting two blades can be installed all), described blade erecting bed 8 comprises groove 9 and blade fixed block 10, blade and blade fixed block 10 are installed on the described groove, are offered angle marked area 11 between described blade and the blade fixed block 10.
3 angles are carved with in described angle marked area 11, are respectively 30 °, 45 °, 60 °.
What described angle marked area 11 was represented is the angle of blade and cutter hub outer end side angle.
Before the processing, with first segment of cutting 3, the 3rd segment of cutting 5, the 5th segment of cutting 7, cutting blade is installed, second segment of cutting 4, the 4th segment of cutting 6 are installed chamfered cutting edge, the chamfered cutting edge setting angle of second segment of cutting 4 is 30 °, the setting angle of the 4th segment of cutting 6 chamfered cutting edges is 45 °, and blade fixed block 10 is installed again, then handle of a knife is connected by bolt with lathe;
What show now is the process of the machining hole of cutter, and the shoulder hole that processes is configured to the first ladder hole depth 9mm, diameter 7mm, the second ladder hole depth 10mm, diameter 8mm, the 3rd ladder hole depth 10mm, diameter 9mm.Described second shoulder hole need be processed 30 ° of chamferings, the 3rd shoulder hole need be processed 45 ° of chamferings.
Add man-hour, first segment of cutting 5 touches object to be processed earlier, locatees, and begins to expand first shoulder hole of dark 9mm, diameter 7mm then;
Continue feeding, second segment of cutting 6 begins to expand second shoulder hole that dark 10mm, diameter 8mm;
Continue feeding, the 3rd segment of cutting 7 is poured out 30 ° of angles of second shoulder hole;
Continue feeding, the 4th segment of cutting 8 expands the 3rd shoulder hole that dark 10mm, diameter 9mm;
Continue feeding, the 5th segment of cutting 9 is finished 45 ° of chamferings of the 3rd shoulder hole;
Expand diameter, the degree of depth and the chamfering of portalling and settle at one go, machine.
Expand the hole depth, the chamfering that and settle at one go, machine.
Example two
Shown in Fig. 2, Fig. 3, Fig. 4, how present embodiment explanation blade erecting bed is installed blade and is adjusted knife edge angular.
This example is only at square blade, and before the processing, the chamfered cutting edge of setting second segment of cutting 4 is installed as 30 °, and its installation steps are as follows:
At first, blade is put into groove 9 places on the blade erecting bed 8;
Next step, with the screwed hole of the tapped through hole alignment indentation 9 of blade, with screw rotate several down, blade can be rotated around screw;
Next step, is with some blade heads of square blade, 30 ° of the angle marked area 11 on the alignment indentation 9;
Next step continues to screw the screw on the blade, fixing getting final product;
Next step is installed on second through hole of groove 9 with blade fixed block 10, connects by screw.
The installation blade finishes.
Chamfering need be replaced by 45 when spending,
At first, unclamp the screw on the blade fixed block, unload blade fixed block 10;
Next step unclamps the screw on the blade, then the blade head is chosen 45 ° of scales of the angle marked area 11 on the groove 9;
Next step, screw on the blade and blade fixed block 10 on screw get final product.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
