Abstract
The utility model announces a kind of grade two sided of opening for the processing of planetary wheel carrier internal arm side and processes a dedicated tool, belongs to engineering machinery processing equipment field.Cutter hub including knife bar and installed in knife bar end；The cutter hub is arranged vertically with knife bar, and installation through-hole is provided with the middle part of cutter hub, and knife bar end is fixed through cutter hub installation through-hole and by trip bolt；The " V " shape inclined-plane being engaged is had in the side of cutter hub with knife bar joint；Described cutter hub one end is respectively fixed with one group of cutting tip close to knife bar side and away from knife bar side.The utility model is cut when opening grade upper side and processing with the cutting tip of upper end two, cut when opening the processing of grade downside with the cutting tip of lower end two, it is small using revolution turning mode, cutting resistance during cutting, high-speed cutting, surface smoothness height and efficiency high can be used.
Description
Technical field
Engineering machinery processing equipment field is the utility model is related to, is particularly used for the processing of planetary wheel carrier internal arm side
One kind opens a grade two sided processing dedicated tool.
Background technology
As shown in figure 3, the uniform planet wheel spindle mounting hole a of planetary wheel carrier, planetary gear are fixed on out shelves two by planet wheel spindle
Between the round boss b of side, it need to ensure open a grade size for two sides round boss in assembling, and two boss differ in size,
It is smaller that shelves are opened in the side of planetary wheel carrier, is restricted by planetary gear pore size, influences travel of spindle, directly using main shaft gyration cutting
It is difficult to all cutting round boss.
A traditional grade side processing method of opening is：
1）Boring bar is stretched into planetary gear axis hole, front end fills white steel bar cutter and carries out scraping to side, with white steel bar cutting edge
Length ensures side form diameter as effective radius of machining；
2）Between stretching into out shelves using slotting cutter on milling machine, scraping is carried out to side.
Using conventional methods the shortcomings that carrying out out the processing of grade side is：
1. being linear contact lay between white steel bar knife scraping cutting edge and workpiece, resistance is big, and scraping rotating speed is low, is also easy to produce during tool sharpening
Shake, influence side finish and open a grade dimensional accuracy；
It is linear contact lay between scraping cutting edge and workpiece, scraping resistance is big, chi 2. slotting cutter side is not real cutting edge
Very little precision is low, and component shaping is poor；
3. shaving cutting resistance is big, there is a shake, efficiency is low.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of high speed, the machining of high dimensional accuracy opens shelves pair
The dedicated tool of side, improve processing efficiency.
The utility model is achieved through the following technical solutions：One kind opens a grade two sided processing dedicated tool, including knife bar and
Cutter hub installed in knife bar end；The cutter hub is arranged vertically with knife bar, is provided with installation through-hole in the middle part of cutter hub, knife bar end passes through
Cutter hub installation through-hole is simultaneously fixed by trip bolt；The " V " shape being engaged is had in the side of cutter hub with knife bar joint
Inclined-plane；Described cutter hub one end is respectively fixed with one group of cutting tip close to knife bar side and away from knife bar side.
It is further：Cutting tip described in every group sets two, the left and right mounting distance phase of the cutting tip of upper and lower side
Alignment, or the 5-6mm that staggers.
The one end of the cutter hub away from cutting tip is provided with locating shoulder.
The cutting tip is fastened on cutter hub by blade screw.
Compared with prior art, the beneficial effects of the utility model：Open when grade upper side is processed with the bite of upper end two
Piece is cut, and is cut when opening the processing of grade downside with the cutting tip of lower end two, using revolution turning mode, cutting resistance during cutting
It is small, high-speed cutting, surface smoothness height and efficiency high can be used.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment one；
Fig. 2 is the left view of the utility model embodiment one；
Fig. 3 is planetary wheel carrier structural representation.
In figure：1st, knife bar, 2, cutter hub, 21, " V " shape inclined-plane, 22, locating shoulder；3rd, trip bolt, 4, cutting tip, 5,
Blade screw；A, planet wheel spindle mounting hole, b, round boss.
Embodiment
It is a specific embodiment of the present utility model below, the utility model is described further in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, one kind opens a grade two sided processing dedicated tool, and cutter hub 2 is arranged vertically with knife bar 1, cutter hub 2
Middle part is provided with installation through-hole, and the end of knife bar 1 is fixed through the installation through-hole of cutter hub 2 and by trip bolt 3.In cutter hub 2 and knife bar 1
The side of joint has the " V " shape inclined-plane 21 being engaged, and ensures the installation accuracy of cutter hub 2；Cutter hub 2 is away from cutting tip 4
Left end be provided with locating shoulder 22, ensure cutter hub 2 assemble after cutting tip 4 operating radius.The upper and lower side difference of the right-hand member of cutter hub 2
One group of cutting tip 4 is fixed with, cutting tip 4 is fastened on cutter hub 2 by blade screw 5；Every group of cutting tip 4 sets two
The distance of two cutting tips 4 is determined by the round boss b diameters that need to be processed, and can also slightly be adjusted；Upper and lower side
The left and right mounting distance of cutting tip 4 align, or the 5-6mm that staggers, to above and below machining two sides it is identical big
Small and different size of round boss b.
