Description
Technical field
The present invention relates to a kind of numerical control vertical lathe suspension type tool changer station positioning accurate control method, belong to numerical control vertical lathe attachment technique field.
Background technology
Structure is simple because having for numerical control vertical lathe novel suspended type tool magazine, low cost of manufacture, dependable performance, the advantage such as easy to maintenance, at home and abroad machine tool field obtains scale application gradually at present, its core driving mechanism is two helical pitch cylindrical cam indexing, car as vertical in: SVT125 ~ 160 High-speed Computer number control series and DVT250 series numerical control double-column found car, the core driving mechanism of suspension type 8 station supporting with it and 12 station tool magazines just have employed " two helical pitch cylindrical cam indexing ", and this tool magazine has plurality of advantages compared with other type tool magazine; But the requirement on machining accuracy of its key components and parts is higher, general process equipment is difficult to ensure.Now found the suspension type 12 station tool magazine of car for DVT250 series numerical control double-column: this tool magazine is that twelve-station rotates tool magazine, cutterhead is circumferentially uniformly distributed 12 cutter holders, each cutter holder is positioned by the cutter holder locating shaft of cutterhead station breach both sides, and therefore the integrated location precision of the cutter holder locating shaft of cutterhead station breach both sides is direct embodiments of the Rotational accuracy of this tool magazine; The crudy of two helical pitch cylindrical cam to the indexing of tool magazine whether steadily, service life and cutterhead location time repetitive positioning accuracy height all have a direct impact; Wherein, bearing mounting hole (the 24-φ 10mm) angular error that index dial distributes at circumferencial direction and centre-to-centre spacing error are the most critical machining accuracies of index dial, the integrated location precision that the height tool setting folder locating shaft of this precision is final has a direct impact, and also determines the whether smooth and easy of the bearing engagement process on cam and index dial; The cutter holder locating shaft installing hole (2-φ 6mm) of each cutter holder dish station breach both sides is relative to the angular error of cutter head center, and be one of crucial machining accuracy of tool magazine dish, this precision directly affects the final integrated location precision of tool magazine dish upper slitter chuck locating shaft; On cutterhead, 12 places' cutter holder dish station breach (12-139mm is uniform) are relative to the angular error of cutter head center; Due to structure restriction, cutter holder locating shaft φ 6 installing hole and station gap edge distance only have 2.5mm; And cutter holder side and station gap edge and cutter holder supporting plate Edge Distance also only have 1.5mm, if it exceedes allowed band relative to the angular error of cutter head center in 12 place's cutter holder station breach processes in machining cutter head; Occur when then often there will be processing cutter holder locating shaft φ 6 installing hole that open-minded hole phenomenon and tool magazine cutter holder in exchanging knives process cannot fall into station breach, cause colliding with cutterhead phenomenon; once there is above-mentioned reason, occur that the possibility of percent defective just can strengthen, be difficult to remedy.The precision controlling of general above-mentioned Novel hung tool magazine critical component, key position is all ensure by high-accuracy process equipment, and its manufacturing cost is higher, if equipment precision is not enough, there will be higher percent defective; And produced tool magazine unstable properties, has a strong impact on the quality of product.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the invention provides a kind of numerical control vertical lathe suspension type tool changer station positioning accurate control method, this a kind of numerical control vertical lathe suspension type tool changer station positioning accurate control method can not only ensure that cam engages smooth and easy with the cam driven bearing on index dial, index dial transposition is steady, precision is more accurate, can also make the cutter holder locating shaft of each cutter holder dish station breach both sides relative to the angular error of cutter head center ± 10 " within.
The present invention solves the technical scheme that its technical barrier adopts: the structure of numerical control vertical lathe suspension type tool magazine inside is: tool magazine support one end connects tool magazine shell, the termination of the other end is provided with reductor, its lower end is provided with two helical pitch cylindrical cam indexing, reductor connects the twin columns worm screw on cam indexing mechanism, twin columns worm screw engages with the cam driven bearing on index dial, index dial lower end connects cutterhead, cutterhead is provided with several cutter holder dish, the two ends of each cutter holder dish are respectively equipped with cutter holder supporting plate, cutter holder supporting plate is equipped with cutter holder locating shaft, the hole at cutter holder two ends is placed on the cutter holder locating shaft on cutter holder dish,
The installation method of described index dial and cam driven bearing is: uniformly inside index plate housing inner rim be drilled with several connecting hole, uniformly in index plate housing outer rim be drilled with several through hole being greater than cam driven bearing axle, index plate housing outer rim side is provided with screwed hole perpendicular to through hole stage casing, centering mold is laid inside index plate housing, cam driven bearing is positioned in through hole and leans against centering mold outer rim, decile gauge block is laid between each cam driven bearing, closed India rubber bar is used to be enclosed within outside cam driven bearing and fastening, cam driven bearing periphery is made to be adjacent to the periphery of centering mold, in each through hole and between cam driven bearing axle, guide rail glue is injected at the screwed hole of index plate housing side, then threaded is screwed into, till when cam driven bearing and index dial faying face place guide rail glue slightly overflow, finally index dial is placed and within 18 hours, make guide rail gelling solid, then mold of feeling relieved is removed,
Cutter holder supporting plate on described cutter holder dish and the installation method of cutter holder locating shaft are: one end of frock truss is fixedly connected on tool magazine support, the vertical connecting tooling stand of the frock truss other end, frock stand bottom vertically connects template, nib in template aligns the cutter holder dish two ends boring on cutterhead, after boring, alignd in the hole that cutter holder supporting plate gets out in advance and locate with shop bolt, then, by the installing hole boring on cutter holder supporting plate, cutter holder supporting plate is fixed on cutter holder dish two ends, shop bolt is removed, installs cutter holder locating shaft; Repeat above-mentioned procedure of processing, can make the two ends of each cutter holder dish that cutter holder supporting plate and cutter holder locating shaft are installed.
The invention has the beneficial effects as follows: effectively solve the difficult problem that bearing mounting hole Working position precision uniform on index dial is difficult to ensure, the index dial accuracy of manufacture of two helical pitch cylindrical cam mechanism the has been had raising of leap, angular error by manufacturing process state best level ± 45 " reach innovation improve after ± 10 " within.Realize the location of cutter holder on cutterhead, play the weight supporting cutter holder, the wearing and tearing preventing cutterhead simultaneously and then improve service life of cutterhead, greatly reduce processing, manufacture difficulty, its obtain every accuracy of manufacture be that usual machining process hardly matches, not only reduce the manufacture risk of finished product; Also increase substantially the service life of product, reduced a large amount of manufacture and maintenance cost, also improve the core competitiveness of enterprise simultaneously.
