Description
technical field:
The utility model relate to be applied to high, the tooth pitch of required precision in the processing of large scale pulley groove comparatively large, cut the precision complicated shaping high-rate cutting process tool comparatively dark, tooth form structure comparison is special, cutting force is larger.
background technology:
The pulley groove precision required in large scale pulley groove machining Practice is high, and the profile of tooth of pulley groove is wide and highly dark.Therefore in the formed machining mode that large scale pulley groove machining Practice middle belt pulley slot machining all adopts half full tooth to cover.Its feed distance is large; Dark by the depth of cut; Thus cause cutting load weight; Resistance to cutting is large.Therefore, require strict especially to the reliable positioning and clamping of cutter.Iron filings chip removal difficulty in side entry machining process, not easily chip breaking.
In existing tooling system, location employing 180 ° of double end profile of tooth contact surface list navigation systems, clamping also just adopts the single clamping system of screw or pressing plate etc.Therefore, the reliability and stability of cutter positioning are lower.
utility model content:
The purpose of this utility model is to provide the large scale complicated race shaping full back cutter that a kind of positioning precision is higher, more reliable, the disconnected chip removal effect of clamping is more excellent.
The utility model is achieved in that
By size wheel slot blade 1, blade pressing screw 2, pressing plate 3, pressing plate housing screw 4, cutter hub 5 forms, the angle of adjacent two walls of the locating slot of cutter hub 5 is 90 °, size wheel slot blade 1 has cuboid to coordinate with the locating slot of cutter hub 5, the angle that adjacent two side-locating faces of cuboid are in 90 °, the another both sides of cuboid respectively have the 1st, 2 teeth, the tooth root of two teeth respectively has upper respectively with cuboid of dust lead face 14, connect below, locating surface is at an angle of 90 positioned in the locating slot of cutter hub 5, size wheel slot blade 1 is pressed in the insert groove of cutter hub by the blade pressing screw 2 be positioned on its centre bore, size wheel slot blade 1, the upper end coplanar of cutter hub 5, the wide 10mm in dust lead face 14 of size wheel slot blade 1, 10 ° of angles are become with the cuboid upper and lower end face of size wheel slot blade, pressing plate 3 is positioned on the hole of size wheel slot blade 1, be fastened on cutter hub 5 by pressing plate housing screw 4.The front end of cutter hub 5 has and the profiling of blade tooth, the cutter hub tooth of size small blade tooth 0.5mm.
The difference that the utility model requires for high accuracy, high reliability positioning and clamping in large scale pulley groove system of processing, carries out the innovative design of the location of tooling system, clamping, disconnected chip removal system respectively.For navigation system, the existing 180 ° of double end profile of tooth contact surface list navigation systems of analysis optimization, turn to the contact surface navigation system of blade and cutter hub by the turn-over that location gets 90 °.For clamping system, adopt blade center's hole screw eccentric clamping, above blade, give pressing plate thrust vertically downward afterwards, under the downward active force of housing screw, realize the firm grip of blade on cutter hub.For disconnected chip removal system, process in blade teeth portion upper end width be slightly wider than wheel groove depth become the dust lead face of 10 ° of angles to carry out disconnected chip removal with blade upper surface.
The relatively original cutter structure system of the utility model from location, designing and developing of innovate of clamping, disconnected chip removal system, positioning precision is higher, clamping is more reliable, chip removal effect of breaking is more excellent.Prove to increase substantially with this new-type cutter converted products precision stability and stability through test, the transposition that cutter produces because of high-rate cutting and the blade clamping unreliable generation because of system collapse and lack basic elimination, the iron filings produced become bulk to get rid of, and show good disconnected chip removal performance.Workman's no longer hook scrap iron removing in process, and the surface quality of workpiece has lifting by a relatively large margin.
The utility model tool has the following advantages:
1,90 ° of L-type locating surface designs: for the existing location structure of existing market, this design increase effectively the contact area between blade and cutter hub locating surface, make location more reliable, ensure that the requirement of large scale pulley groove machining high-precision better.Avoid original cutter to adopt in the unreliable and application process in 180 ° of double end profile of tooth contact surfaces location easily to cause and do not use the blade profile of tooth of one side to collapse the adverse effects such as scarce simultaneously.
2, trip bolt adds platen clamp structure: the relatively original 180 ° of double end blades of this structure adopt single top board to clamp, provide larger blade clamping rigidity, avoid the micrometric displacement of blade in process, make cutter can bear larger cutting force, thus effectively improve machining accuracy and the working (machining) efficiency of workpiece, the raising of blade durability is also had very great help simultaneously.
3, inserts groove structural design: for iron filings chip removal difficulty in side entry machining process, the not easily feature of chip breaking, have employed on blade and open chipbreaker structures, more effectively ensure that the chip breaking effect in working angles and iron filings traffic organising, decrease the iron filings scratch machined surface and phenomenon of forging a knife that cause because chip removal is not smooth.
