Description
Technical field
This technology relates to method for processing crankshaft and the processing unit (plant) being processed the rotor journal of bent axle.
Background technology
Bent axle is parts common, broad-spectrum.Bent axle has a rotor journal, and the axis of rotor journal is off relative to crankshaft center line.In order to rotor journal is processed, there is a lot of crankshaft processing device at present.But these processing unit (plant) structures are complicated, use inconvenience, and working (machining) efficiency is low, and it is difficult to ensure that machining accuracy.
Summary of the invention
The purpose of this technology is to provide a kind of simple in construction, easy to use, machining accuracy is high, the crankshaft processing device that quickly can be processed the rotor journal of bent axle.
The crankshaft processing device of this technology, described bent axle has rotor journal, and the axis of rotor journal is eccentric relative to crankshaft center line；This processing unit (plant) includes frame, rotary table, cutterhead, cutter；Cutterhead can being arranged on rotary table around own axis；The axis of cutterhead overlaps with crankshaft center line, and the cutter for cutting rotor journal is arranged on the inner circumferential of cutterhead；Rotary table can being arranged in frame around own axis, the axis of rotary table and the dead in line of rotor journal；Rotary table is connected with the rotary table driving means driving rotary table to rotate being arranged in frame；The cutterhead driving device that cutterhead rotates with the band movable knife disc being arranged on rotary table is connected.
The beneficial effect of this technology: when cutterhead own rotation, certain point on periphery on rotor journal can be processed under the drive of cutterhead by cutter；When cutterhead revolves round the sun along with rotary table, the axis that cutter just rotates around rotor journal along with rotary table rotates, and so, cutter can complete processing to the periphery of rotor journal.Cutter is on cutterhead, the structure that is arranged on rotary table of cutterhead, and rigidity is strong, and machining accuracy is high.
Above-mentioned crankshaft processing device, described cutter is milling cutter.
Above-mentioned crankshaft processing device, rotary table driving means includes the motor being arranged in frame, passes through belt transmission between motor output shaft and rotary table.
Above-mentioned crankshaft processing device, cutterhead driving device includes the motor stator being fixed on rotary table, rotates the rotor being arranged on motor stator inner circumferential；Cutterhead is fixed in the inner circumferential of rotor.
This technology provides a kind of quickly can being processed the rotor journal of bent axle and method for processing crankshaft that machining accuracy is high simultaneously.
This method for processing crankshaft, described bent axle has rotor journal, and the axis of rotor journal is eccentric relative to crankshaft center line；This processing method is, cutterhead rotates and is arranged on rotary table, by the cutterhead coaxial with crankshaft center line around own axes relative to the rotation of rotary table, simultaneously with the rotary table of rotor journal axis coaxle around own axis, with the cutter in cutterhead inner circumferential, rotor journal is cut.
The beneficial effect of this processing method: due to rotary table and rotor journal axis coaxle, cutterhead is coaxial with crankshaft center line, so along with cutterhead and the rotation of rotary table, rotor journal can be processed by the cutter on cutterhead.Due to the axis of cutterhead relative to the eccentric throw of rotary table equal to the rotor journal of bent axle relative to the eccentric throw of crankshaft center line, so high to the machining accuracy of rotor journal.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of crankshaft processing device.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the schematic diagram after one angle of own axis of the rotary table in Fig. 2.
Detailed description of the invention
With detailed description of the invention, this technology is described further below in conjunction with the accompanying drawings.
Seeing the crankshaft processing device shown in Fig. 1-3, including rack 1 fixes motor 2, and rotary table 3 can being arranged in frame around own axis by bearing 4.The periphery fixed pulley 5 of rotary table.Belt wheel 5 is connected with the belt pulley 6 on the output shaft of motor 2 by belt (not shown).
Motor stator 7 is fixed on rotary table, and rotor 8 is rotated by bearing 9 and is arranged on motor stator inner circumferential；Gland 16 is fixed on motor stator, positions bearing 9.Cutterhead 10 is fixed in the inner circumferential of rotor.4 milling cutters 11 are evenly arranged in the inner circumferential of cutterhead.
Motor stator 7, rotor 8, cutterhead 10 are coaxial, but they are off setting with rotary table 3.
The axis of cutterhead (motor stator, rotor) overlaps with the axis 151 of processed bent axle 15, and the axis of rotary table overlaps with the axis 152 of the rotor journal 153 of processed bent axle 15.It is to say, the axis of cutterhead (motor stator, rotor) is equal with the offset of processed crankshaft eccentric axle journal relative to the offset of rotary table 3.
Motor stator 7, rotor 8 belong to prior art, and motor stator is mainly made up of stator core, stator winding, and rotor is mainly made up of rotor core, rotor windings etc..In this patent, the stator core being embedded with stator winding is fixed on rotary table, and the rotor core periphery being embedded with rotor windings is arranged in stator core by bearing rotation, the inner circumferential fixation cutter head of rotor core.
When rotor journal is carried out milling, after motor stator energising, rotor rotates, and band movable knife disc rotates around the axis 151 of processed bent axle；Meanwhile, motor 2 is rotated around the axis of the rotor journal of processed bent axle by belt drive rotary table (with motor stator, rotor, cutterhead etc.).So, rotary table rotates one week, and the cutter in cutterhead inner circumferential completes the milling of a week to rotor journal.
