Abstract
The utility model discloses a transposable stepped railhead planer tool, comprising a tool body (1), multiple blades (2) and multiple blade installation tables (3), wherein the blade installation tables (3) are located on the tool body (1) and arranged in a stepped shape; the blade installation tables (3) is obliquely arranged; the blades (2) are arranged on the blade installation tables (3) and are contacted with a positioning surface I and a positioning surface II which are vertical to each other and vertical to the blade installation tables (3); the adjacent blades (2) are staggered and overlapped with each other; and the edges of the blades (2) form an integrated continuous cutting edge in the cutting direction. The transposable stepped railhead planer tool has the advantages of impact and rational structure, easiness in operation, firm and rational positioning, long service life and high production efficiency.
Description
Technical field
The utility model relates to a kind of machine tool, but is specifically related to a kind of transposition staged rail head planing tool.
Background technology
The rail head planing tool that has had various ways in the market presss from both sides whole glaive chip such as welded type, machine.Original rail head planing tool is in process; Owing to be that whole cutting edge is participated in cut simultaneously; Iron filings are too wide, and the cutting resistance that cutting edge roundness receives is very big, and the some positions of blade or several position are damaged; Make the product surface quality that processes poor, so just must be with whole cutting edge regrinding again.The regrinding precision of cutting edge is high, and this requires operating personnel that higher specialized capability is arranged, and operation is not only wasted time and energy, and the regrinding number of times is limited, is not suitable for very much producing in enormous quantities processing.Therefore manufacturing enterprise to hope to obtain a kind of compact conformation reasonable, simple to operate, firm position is reliable, the life-span is long, can satisfy requirement on machining accuracy, the novel rail head planing tool that can enhance productivity again.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, provides a kind of compact conformation reasonable, simple to operate, and firm position is reliable, and the life-span is long, but the high transposition staged rail head planing tool of production efficiency.
The purpose of the utility model realizes through following technical scheme:
But transposition staged rail head planing tool; It comprises cutter hub, a plurality of blade and a plurality of blade erecting bed, and the blade erecting bed is positioned on the cutter hub and stepped arrangement, and the blade erecting bed is obliquely installed; The inclination alpha of blade erecting bed is 2 ° ~ 10 °; The angle of inclination beta of blade erecting bed is 2 ° ~ 10 °, and blade is arranged on the blade erecting bed, blade with contact with locating surface two perpendicular to blade erecting bed and mutually perpendicular locating surface one; The interlaced overlap joint of adjacent blade, the blade on the blade are formed the cutting edge of continuous whole on machining direction.
Blade is circular arc tooth shape or straight line tooth shape.
Blade passes through bolt.
Blade is an indexable insert tip, throw away tip.
The advantage of the utility model is:
1. blade is installed on the stepped blade erecting bed, compact conformation, and the blade when work on each blade is participated in cut separately, presss from both sides whole glaive sheet than welded type, machine, has disperseed cutting resistance, has improved service life;
2. after the blade wearing and tearing, blade inserts to new blade and can reuse, and compares the regrinding cutter and has saved the operating time greatly, and lathe still less effectively raises production efficiency downtime in the whole working angles;
3. adopt blade erecting bed and two locating surfaces to carry out spacing and the location, firm position is reliable;
4. when design, blade can be overlapped to form multiple geomery different cutting, can be used for processing difform rail head.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, the protection domain of the utility model is not limited to the following stated.
Like Fig. 1, Fig. 6 and shown in Figure 9, but transposition staged rail head planing tool, and it comprises cutter hub 1, a plurality of blade 2 and a plurality of blade erecting bed 3; Blade erecting bed 3 is positioned on the cutter hub 1 and stepped arrangement; Blade erecting bed 3 is obliquely installed, and blade 2 is arranged on the blade erecting bed 3, blade 2 with contact with locating surface 25 perpendicular to blade erecting bed 3 and mutually perpendicular locating surface 1; Adjacent blade 2 interlaced overlap joints, the blade 6 on the blade 2 is formed the cutting edge 7 of continuous whole on machining direction.Blade 2 is fixing through bolt 8.
Like Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, blade 2 is an indexable insert tip, throw away tip, and blade 2 is provided with a plurality of blades 6, and blade 6 both can also can be the straight line tooth shape for the circular arc tooth shape.
As shown in Figure 8, in left view, blade erecting bed 3 is tilted to the right; Inclination alpha is 2 ° ~ 10 °, and is as shown in Figure 7, in front view; Blade erecting bed 3 is tilted to the left simultaneously; Angle of inclination beta is 2 ° ~ 10 °, and this makes blade 2 when work, always blade 6 aimed at object to be processed, guarantees carrying out smoothly of cutting.
As shown in Figure 8; Adjacent blade 2 interlaced overlap joints, continuous, as shown in Figure 9 to guarantee the cutting edge of forming; Combination through circular arc tooth shape and straight line tooth shape; Blade 6 has been formed the cutting edge 7 of continuous whole, and blade 2 is participated in cutting operation from top to bottom successively when work, finally obtains complete machined surface.
The utility model is processed on numerical control machining center through CAD and manufacturing, can guarantee blade 2 overlap joints accurately, obtains high-precision cutting edge 7.Can during fabrication blade 2 be overlapped to form various difform cutting edges 7 according to practical condition.
