Description
Technical field
The utility model relates to a kind of fine finishining special combination fixture, is a kind of precise processing device for various planet carriers, planetary gear, realizes the Precision Machining of planet carrier, planetary gear in common machining center equipment situation.Various dissimilar planet carriers, the planetary gear fine finishining such as round, square are had to directive significance.
Background technology
Planetary Gear Transmission has can be realized the different multichannel transmission of gearratio, commutation and obtain the functions such as very big reduction of speed compares by measures such as few teeth differences, because being widely used in the fields such as lathe, automobile and wind-powered electricity generation.Planet carrier is one of primary structure of planetary transmission, in Gear Planet Transmission, in Ta Shi mechanism, bear the part of moment of face maximum, axle and bearing are just contained on planet carrier, for guaranteeing the correct engagement of centre wheel and planetary gear, between the hole system of axle, must there be strict centre-to-centre spacing and position degree requirement, the form tolerance in each hole self also requires quite high simultaneously, if the tolerance between the system of hole surpasses or each hole self overproof of aperture, all can directly affect installation accuracy and the transmission accuracy between planetary gear pair.Planet carrier difficult processing, required precision is high, in reality processing, how to adopt rational processing method and supporting special combination fixture to process high-precision planet carrier and just seems very important like this.Its processing features of planet carrier is that required precision is high, in order to reach technical requirement on design, Precision Machining all adopts precision jig boring machine to carry out fine finishining, and precision is mainly leaned on the accuracy guarantee of jig borer, but this method requires higher to operator's level of skill, and jig boring machine belongs to rare equipment, lathe inadequate resource, working ability is limited, during processing single products, can adopt in this way, but it is very inadaptable in batch machining, just to seem.Because jig boring machine is the relation of two vertical coordinates the location resolution in each hole when machining hole is, then by operation lathe, realize the accurate movement of coordinate position, based on this principle, if process planet carrier part on general-purpose machining center lathe, design and produce this fine finishining built-up jig and carry out Precision Machining planet carrier, planetary gear, allowing machine tool chief axis only move up and down a position (is X coordinate, Y coordinate does not move, only carry out the movement of Z coordinate), X-axis and Y-axis no longer move, eliminated the accumulated error in moving process, can guarantee the required precision of planet carrier.
Utility model content
Its object of the utility model is just to provide a kind of planet carrier fine finishining special combination fixture, there is the feature simple, practical, convenient, precision is high, the in the situation that of general-purpose machining center lathe, realize planet carrier Precision Machining, can be used for various dissimilar planet carriers processing such as various round, squares.
The technical scheme that the utility model is taked to achieve these goals, comprise T-shaped bolt, clamp base, isometry block, briquetting, planet carrier, positioning core axle, locking nut, positioning sleeve, alignment pin, positioning seat, numerical control rotating platform, the numerical control rotating platform of described built-up jig is fixed on machining center workbench, clamp base lies on numerical control rotating platform, by T-shaped nut, be connected with numerical control rotating platform, high accuracy isometry block is lain in the boss face of clamp base upper end, positioning core axle is arranged in clamp base, planet carrier is placed on isometry block, by positioning core axle, be contained on built-up jig, and be provided with locking nut and briquetting and compress, by alignment pin, planet carrier is carried out the locking positioning of circumferencial direction simultaneously.
Concrete making step is as follows:
1) repair and grind high accuracy isometry block, flatness reaches 0.005;
2) clamping fixture for correcting locating surface is contour, and the centre of gyration and rotation of rotary table center conllinear
3) planet carrier is arranged on fixture positioning core axle, packs positioning sleeve into, with nut, compress planet carrier, insert alignment pin location, adjustment programme, sets up machining coordinate system;
4) rotation numerical control rotating platform, allowing machine tool chief axis only move up and down a position (is X coordinate, Y coordinate does not move, only carry out the movement of Z coordinate), X-axis and Y-axis no longer move, and have eliminated the accumulated error in moving process, three holes or four holes or more planet hole, as long as guarantee the precision between the system of hole by rotation numerical control rotating platform, carry out successively bore hole.
Compared with prior art, the utility model has the advantage of:
1) simply, conveniently, precision is high; Provide a kind of, the in the situation that of general-purpose machining center lathe, planet carrier is carried out to precise processing device, simple to operate, accuracy is high.
2) adopt built-up jig to coordinate processing center machine tool various dissimilar planet carriers, planetary gear can be carried out to Precision Machining.
3) the utility model can realize that shape is similar, the Precision Machining of the different planet carriers of size, planetary gear.What adopt is positioning core axle location and face clamping, part for different radial dimensions or different axial dimensions, only need to change positioning core axle and can realize the clamping to workpiece, thereby effectively reduce the design and manufacture cost of fixture and produce the preparatory period, the labour intensity that has reduced workman, has improved production efficiency.
