Abstract
The utility model relates to a replaceable carbide blade hob, which is characterized by comprising a plurality of cutter bodies (1) with the same structure, wherein each cutter body (1) is provided with a plurality of indexable and replaceable carbide blades (2) at equal intervals along the direction of a circumference helical line; the cutter bodies (1) are connected in series one by one through plane positioning keys (3); both ends of each cutter body (1) are provided with a gland (4); and the cutter bodies (1) are connected with the glands (4) into a whole through connecting bolts (5). The advantages (the generating principle and generality of an involute line) of hob cutting are kept, and the defects that the common hob has short service life and low efficiency and needs regrinding are overcome. The replaceable carbide blade hob is matched with a high-efficiency gear hobbing machine, and production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of machining tool, and especially a kind of gear adds cutter, specifically a kind ofly adds the interchangeable carbide chip hobboing cutter that work gear is used.
Background technology
Domestic in recent years Gear Processing industry has had many high efficiency gear hobbing machines, but lacks the High-efficient Hobbing Cutter that is complementary with it.Conventional hobboing cutter is owing to be subjected to the restriction of material, and cutting speed, the degree of depth, feed all do not increase, and the efficient of efficiently rolling can not get performance.Usually everybody uses the dish milling cutter to slot, though the dish milling cutter can improve working (machining) efficiency, the gear of opening groove also will carry out the profile of tooth that gear hobbing could produce involute with hobboing cutter, and the efficient of efficiently rolling does not still find full expression.
Summary of the invention
The purpose of this utility model is the problem that causes working (machining) efficiency to improve at for want of corresponding cutter of existing high efficiency gear hobbing machine, designs a kind of working (machining) efficiency that can improve, and prolongs the interchangeable carbide chip hobboing cutter in processing life-span.
The technical solution of the utility model is:
A kind of interchangeable carbide chip hobboing cutter, it is characterized in that it comprises the identical cutter hub of some block structures 1, each cutter hub 1 has indexable, removable some carbide chips 2 along circumference hand of helix equidistant placement, described cutter hub 1 is together in series one by one by plane positioning key 3, the two ends of cutter hub 1 respectively are provided with a gland 4, and cutter hub 1 connects into an integral body by connecting bolt 5 and gland 4.
The quantity of described cutter hub 1 is six, and 16 indexable, removable carbide chips 2 are installed on each cutter hub 1.
Four seamed edges of described carbide chip 2 form the cutting edge that rolling cut is used separately, there is circular arc to be connected to form the head circular arc of hobboing cutter between the adjacent seamed edge, cut the root easement curve of formative gear in the process in exhibition, the seamed edge of each carbide chip 2 drops on the involute helicoid of hobboing cutter.
Between the described cutter hub 1 positioning key 3 is installed, positioning key 3 is distributed between the faying face of adjacent cutter hub 1.
The thickness of described cutter hub is that axial length equals: processed module * π ÷ cos (λ), λ is the lead angle of hobboing cutter.
The beneficial effects of the utility model:
The stock-removing efficiency of a interchangeable carbide chip hobboing cutter of the present utility model is 7～8 times of common hobboing cutter.Be more than 10 times of common high-speed steel the service life of blade.
B has saved the sharpening time.
The c cutter hub never cancels, once investment, permanent being benefited.
The d blade has versatility, and kind is few, be convenient to management.
E the utility model had both kept the generating principle and the versatility of the superiority involute of hobboing cutter cutting, overcome again hobboing cutter life-span commonly used short, efficient is low, the shortcoming that will reface.It and the supporting use of high efficiency gear hobbing machine are enhanced productivity greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of interchangeable carbide chip hobboing cutter, it comprises the identical cutter hub of 6 block structures 1, the thickness of cutter hub 1 is that axial length equals: processed module * π ÷ cos (λ), λ is the lead angle of hobboing cutter.Each cutter hub 1 has indexable, removable 16 carbide chips 2 along circumference hand of helix equidistant placement, four seamed edges of carbide chip 2 all may be separately formed the cutting edge that rolling cut is used, there is circular arc to be connected to form the head circular arc of hobboing cutter between the adjacent seamed edge, cut the root easement curve of formative gear in the process in exhibition, the seamed edge of each carbide chip 2 drops on the involute helicoid of hobboing cutter.Described cutter hub 1 is together in series one by one by plane positioning key 3, and the two ends of cutter hub 1 respectively are provided with a gland 4, and cutter hub 1 connects into an integral body by connecting bolt 5 and gland 4.As shown in Figure 1.Plane positioning key 3 is distributed on 4 equal portions on the composition surface of cutter hub, and it promptly plays the role of positioning, bears the cutting moment of torque again, as shown in Figure 2.
Details are as follows:
1. hobboing cutter of the present utility model is nested together by 6 spiral cutter hubs edge, and 16 carbide chips are arranged on each cutter hub, and blade can dismantle, can transposition.The seamed edge of each blade can use as cutting edge.Cutter hub never cancels.Hobboing cutter need not refaced, only need to change blade and just can use.
2. the blade of hobboing cutter is made by carbide alloy, has hardness height, advantage such as wear-resisting, high temperature resistant, is the key point that improves hobboing cutter efficient.The blade external form is a cuboid, and two adjacent edges have circular arc to connect, form the head circular arc of hobboing cutter, cuts the root easement curve of formative gear in the process in exhibition.The seamed edge of each blade must fall on the involute helicoid of hobboing cutter.
3. the linear velocity of hobboing cutter can be up to 150m/min, be to realize high-speed cutting, and hobboing cutter will carry out dynamic balance running after all having assembled, according to G0.4 or be higher than this standard-required and carry out.
4. hobboing cutter of the present utility model need not refaced, cutter hub never cancels.Only needing to change blade just can use.Can on plain grinding, carry out reconditioning after the blade of changing completes a set, allow about wear down 0.5mm.The lip surface of hobboing cutter grinds off 0.5mm, to the use of hobboing cutter and precision without any influence.Can transposition use 4 times again after the blade reconditioning.
5. hobboing cutter of the present utility model has versatility, same modulus, and the gear of same pressure angle can be processed hobboing cutter with same.Needing only outfit uses one every kind on the specification hobboing cutter of modulus 10,12,14,16,18,20,22,25,28,30 always, can cover all substantially.Blade can be general, and great majority all are standards, can directly purchase.This hobboing cutter is used for high efficiency gear hobbing machine, can realize that a gear hobbing of workpiece is shaped.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
