Description
Technical field
This technology relates to method for processing crankshaft and the processing unit (plant) that the rotor journal of bent axle is processed.
Background technology
Bent axle is common, broad-spectrum parts.Bent axle has a rotor journal, and the axis of rotor journal is eccentric with respect to crankshaft center line.For rotor journal is processed, there are at present a lot of crankshaft processing devices.But these processing unit (plant) complex structures, are used inconvenience, and working (machining) efficiency is low, and is difficult to guarantee machining accuracy.
Technology contents
The object of this technology be to provide a kind of simple in structure, easy to use, machining accuracy is high, the crankshaft processing device that can process the rotor journal of bent axle fast.
The crankshaft processing device of this technology, described bent axle has rotor journal, and the axis of rotor journal is eccentric with respect to crankshaft center line; This processing unit (plant) comprises frame, rotary table, cutterhead, cutter; What cutterhead can rotate around self axis is arranged on rotary table; The axis of cutterhead overlaps with crankshaft center line, is arranged on the interior week of cutterhead for the cutter that rotor journal is cut; What rotary table can rotate around self axis is arranged in frame, the axis of rotary table and the dead in line of rotor journal; The rotary table drive unit that rotary table rotates at the drive rotary table being arranged in frame is connected; Cutterhead is connected with the cutterhead driving device rotating with movable knife disc being arranged on rotary table.
The beneficial effect of this technology: when cutterhead self rotates, cutter can be to rotor journal under the drive of cutterhead on certain point in periphery process; When cutterhead revolves round the sun along with rotary table, cutter just rotates along with the axis that rotary table rotates around rotor journal, and like this, cutter can complete processing to the periphery of rotor journal.Cutter on cutterhead, cutterhead is arranged on the structure on rotary table, rigidity is strong, machining accuracy is high.
Above-mentioned crankshaft processing device, described cutter is milling cutter.
Above-mentioned crankshaft processing device, rotary table drive unit comprises the motor being arranged in frame, between motor output shaft and rotary table, passes through belt transmission.
Above-mentioned crankshaft processing device, cutterhead driving device bag is fixed on the motor stator on rotary table, the rotor that rotation is arranged on week in motor stator; Cutterhead is fixedly on the interior week of rotor.
This technology provide simultaneously a kind of can be fast to the rotor journal of bent axle is processed and machining accuracy is high method for processing crankshaft.
This method for processing crankshaft, described bent axle has rotor journal, and the axis of rotor journal is eccentric with respect to crankshaft center line; This processing method is, cutterhead rotates and arranges on rotary table, by the rotation with respect to rotary table around self axis with the coaxial cutterhead of crankshaft center line, rotate around self axis with the rotary table of rotor journal axis coaxle simultaneously, with the cutter on week in cutterhead, 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 the rotation of cutterhead and rotary table, the cutter on cutterhead can be processed rotor journal.Because the axis of cutterhead equals the rotor journal of bent axle with respect to the eccentric throw of crankshaft center line with respect to the eccentric throw of rotary table, 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.
To be rotary table in Fig. 2 rotate the schematic diagram after an angle around self axis to Fig. 3.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this technology is described further.
Referring to the crankshaft processing device shown in Fig. 1-3, including rack 1 fixed electrical machinery 2, what rotary table 3 can rotate around self axis by bearing 4 is arranged in frame.The periphery fixed pulley 5 of rotary table.Belt wheel 5 is connected by the belt pulley 6 on the output shaft of belt (not shown) and motor 2.
Motor stator 7 is fixed on rotary table, and rotor 8 is rotated and is arranged on week in motor stator by bearing 9; Gland 16, being fixed on motor stator, positions bearing 9.Cutterhead 10 is fixedly on the interior week of rotor.4 milling cutters 11 were evenly arranged on the interior week of cutterhead.
Motor stator 7, rotor 8, cutterhead 10 are coaxial, but they and rotary table 3 are eccentric settings.
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.That is to say, the axis of cutterhead (motor stator, rotor) equates with the offset of processed crankshaft eccentric axle journal with respect to the offset of rotary table 3.
Motor stator 7, rotor 8 belong to prior art, and motor stator mainly contains stator core, stator winding forms, and rotor is mainly comprised of rotor core, rotor winding etc.In this patent, the stator core that is embedded with stator winding is fixed on rotary table, and the rotor core periphery that is embedded with rotor winding is rotated and is arranged in stator core by bearing, interior all fixation cutter heads of rotor core.
When rotor journal is carried out to milling, after motor stator energising, rotor rotates, and the axis 151 with movable knife disc around processed bent axle rotates; Meanwhile, motor 2 drives rotary table (with motor stator, rotor, cutterhead etc.) to rotate around the axis of the rotor journal of processed bent axle by belt.Like this, rotary table rotates one week, and the cutter in cutterhead on week completes the milling of a week to rotor journal.
