Abstract

The invention relates to the machining field and provides a combination knife row which aims at solving the problem that machining coaxiality and accuracy are difficult to ensure, and machining cost and maintaining cost are high due to the fact that a numerical control vertical lathe is often adopted when some rotary multi-step products are machined, and multiple position change and knife change are required. The combination knife row is characterized in that a plurality knife rows are installed on a knife rest, a knife shaft and a knife clamp are installed on each knife row, various cutters of different types are installed on the knife clamps, and the installation angle and the stretching length of the cutters can be selected according to requirements. The knife row has the advantages of adapting to various different machining requirements, remarkably improving machining accuracy and efficiency and reducing production cost, maintaining cost and the like.

Description

A kind of combined blade row of high-efficient cutting
Technical field
The present invention relates to field of machining, especially tool for cutting machining.
Background technology
Wheel hub is a kind of rotary type, the machinofacture of many steps, after wheel hub and drive axle, wheel shaft, tire assembling, the driving, the walking mechanism that form engineering machinery, both undertaken the propagation function of exporting huge moment of torsion from drive axle, carrying again simultaneously engineering machinery under disliking labourer's condition during operation from the impulsive torque of tire.This part except self requirement of strength height, its accurate to dimension, bearings at both ends installation position axiality requires all higher.
Existing processing technology is to utilize numerical control vertical lathe processing, and a minute two procedures completes.
(1) clamp little cylindrical, head is thick, and the large end end face of finish turning, cylindrical and endoporus reach drawing requirement;
(2) with axle location, hook pressing plate is pressed the large end face back side, and thick, each step cylindrical of finish turning microcephaly and endoporus reach drawing requirement.
There is following defect in this processing method:
(1) adopt the processing of axle locate mode, be subject to the joint effect of machine spindle center and chuck centre of gyration coaxiality deviation and apotting spindle and workpiece hole fit clearance, after processing, the coaxial accuracy of workpiece is difficult to guarantee.
(2) for meeting the requirement on machining accuracy of this type of part, 5 station cutter racks of the former apolegamy of equipment, the number of cutters that process need to be used is many, and needs multiple rotary tool changing, easily causes knife rest to damage, and the purchase cost of knife rest and maintenance cost are all very high.
(3) tactical diameter of knife rest is large, and during transposition tool changing, knife rest need be removed enough safety travels, then return, and required non-cutting time is longer, and comprehensive stock-removing efficiency is low.
Summary of the invention
Object of the present invention can adapt to multiple cutting requirement, the combined blade row of high-efficient cutting that machining accuracy and working (machining) efficiency are high for providing a kind of.
The technical solution used in the present invention is as follows:
A kind of combined blade row of high-efficient cutting, there is knife rest 7, cutter shaft 4 is housed on knife rest 7, in cutter shaft 4 ends, cutter holder 5 is housed, a plurality of blade rows 1,2,3 are housed on knife rest 7, between adjacent blade row, be separated by 45 °-250 °, cutter shaft 4 and cutter holder 5 are housed on blade row, several dissimilar cutters 6 are housed on cutter holder 5.The cutter fixing threaded hole on cutter holder 5 with a plurality of diverse locations, selects fixing threaded hole according to the required setting angle of cutter 6 and extension elongation.The length of cutter shaft 4 is different, selects as required assembling.
In wheel hub processing, select to have the combined blade row of three blade rows, the corresponding different cutting cutter holders of configuration, control by numerical control program respectively, and clamped one time blade row, just can complete the Roughing and fine machining technique at each position.Whole manufacture simplification is: (1) folder microcephaly, rough turn big end surface and cylindrical; (2) folder major part, thick, the little end surface of finish turning and cylindrical.
The present invention has following beneficial effect:
First reached the requirement that adapts to multiple cutting, the requirement that crudy and efficiency are high, and have:
(1) use knife rest quantity to reduce to 32 by former 52;
(2) when knife rest uses, also alleviated the load weight of whole knife rest, the frequency of maintenance of numerically-controlled slide is reduced to 1 times/year by 6 times/year, reduces every year approximately 30,000 yuan of equipment item maintenance costs;
(3) transposition tool changing is reduced to only 3 times by original 6 times, has greatly reduced cutterhead transposition non-cutting time, makes this operation single-piece by 20 minutes/part, be reduced to 10 minutes/part process time, and production efficiency doubles;
(4) clamped one time complete the Roughing and fine machining of porose system, 100% guarantees axiality requirement, the up-to-standard rate of synthetic obstetric obviously promotes.
Accompanying drawing explanation
For content of the present invention is more likely to be clearly understood, below according to a particular embodiment of the invention and by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is the combined blade row structural representation of a kind of high-efficient cutting of the present invention.
Fig. 2 is the combined blade row machining sketch chart of the present invention.
A figure is combination blade row 3 machining sketch charts
B figure is combination blade row 2 machining sketch charts
C figure is combination blade row 1 machining sketch chart
In figure, be labeled as: 1-blade row 1,2-blade row 2,3-blade row 3,4-cutter shaft, 5-cutter holder, 6-cutter, 7-knife rest.
The specific embodiment
Now by following examples, also by reference to the accompanying drawings technical solution of the present invention is further illustrated.
Embodiment 1
As shown in Figure 1 and Figure 2, knife rest is a regular pentagon body, blade row 1, blade row 2 and blade row 3. blade rows 1 are housed respectively by cutter shaft on three adjacent successively limits, left and right inclined to one side billmpse tool forms, blade row 2 is by cutter shaft, left and right inclined to one side billmpse tool forms, and blade row 3 is comprised of cutter shaft, end face grooving insert and billmpse tool.When processing wheel hub, a clamped one time just can complete three work steps in operation:
Tooling step A, is undertaken by combination blade row 3, completes successively the roughing in end face groove and upper bearing (metal) hole;
Tooling step B, is undertaken by combination blade row 2, completes successively roughing and the fine finishining in lower bearing hole;
Tooling step C, is undertaken by combination blade row 1, completes successively the fine finishining of upper bearing (metal) hole, upper surface and cylindrical.
