Abstract
The invention discloses an X-axis ball screw assembly fixture of a numerically controlled lathe and a method for using the X-axis ball screw assembly fixture of the numerically controlled lathe. The X-axis ball screw assembly fixture comprises a positioning core rod, a front guide sleeve and a rear guide sleeve. The front guide sleeve and the rear guide sleeve are respectively matched with two holes in a large carriage of the numerically controlled lathe for assembling an X-axis ball screw bearing, the diameter of the positioning core rod is matched with a bore of an X-axis nut seat, and the X-axis nut seat penetrates through the positioning core rod to be in directly matched grinding with a plane on an upper carriage, which is linked with the X-axis nut seat. When the X-axis ball screw assembly fixture is used, complicated measuring and match grinding processes can be reduced when operation workers assemble, the assembly reliability of an X-axis ball screw can be ensured, the assembly quality is improved, the influence of the assembling experience of a worker on the production efficiency is reduced, new workers can also quickly master the operation skill, so that the assembly efficiency is effectively improved, the assembly quality of the X-axis ball screw of the numerically controlled lathe can be ensured, and the lathing quality of the numerically controlled lathe can also be greatly improved.
Description
Technical field
The present invention relates to the assembly tooling of a kind of numerically controlled lathe X-axis ball screw and using method thereof.
Background technology
The X-axis assembly is one of vitals of numerically controlled lathe, is mainly used in the in-movement that realizes lathe.The X-axis drive motors drives X-axis ball screw through shaft coupling and rotates, by ball screw nut gyration is changed into rectilinear motion, link by feed screw nut's seat and the ball screw nut that is assemblied in upper planker again, planker carries out horizontal movement in the drive, thereby has realized being installed in the infeed motion of electric driving tool post on the planker.Its processing, assembling directly have influence on the quality of machine cut processing, impact on whole machine tool capability is very large, such as processing, install badly, all faults such as have that shake is sent out in cutting, screw mandrel is easily broken, backlass is overproof, X-axis bumpy motion, turning end lines be unintelligible, and roughness is low.
In the prior art, the assembling of X-axis ball screw is to increase a cushion block between X-axis nut seat and upper planker, method by measurement, match grinding cushion block guarantees X-axis ball screw axis and saddle plane parallel, and such one is to have increased spare and accessory parts, again so that cooperate intensity to be not so good as directly combination by force; The 2nd, because the rigidity of screw mandrel is inadequate, the numerical value of measurement can not guarantee precision; The 3rd, very high to operator's qualification requirement, need simultaneously repeatedly to measure and match grinding, efficient is not high.It is as Main Basis take experience that the workman assembles X-axis ball screw, the qualification of workman's operation is very large on the impact of assembly quality, such as Rig up error, the axis of screw mandrel can produce bending, forward and backward two ends at stroke can produce very large radial load, all faults such as have that shake is sent out in cutting, screw mandrel is easily broken, backlass is overproof, bumpy motion, turning end lines be unintelligible, and roughness is low can make the X-axis ball screw early fatigue excessively fracture when serious.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the assembly tooling of a kind of numerically controlled lathe X-axis ball screw and using method thereof are provided.
The assembly tooling of a kind of numerically controlled lathe X-axis ball screw, it comprises location mandril and forward and backward fairlead.Forward and backward fairlead matches with two holes of assembling X-axis ball screw bearing on the numerically controlled lathe saddle respectively, the location mandril diameter matches with X-axis nut seat endoporus, directly with on the upper planker carries out facing-up with the joining plane of X-axis nut seat after the X-axis nut seat is through on the location mandril.
The assembly method of a kind of numerically controlled lathe X-axis ball screw assembly tooling may further comprise the steps:
1) the forward and backward fairlead of packing into successively in the two ball screw dead eyes on saddle penetrates location mandril again, pierces into the X-axis nut seat at location mandril;
2) greatly to the value that exceeds of measuring on the X-axis nut seat on the plane and upper planker and between the faying face of X-axis nut seat, match grinding X-axis nut seat stays 0.2mm left and right sides surplus to carry out facing-up;
3) use on the planker with face that the X-axis nut seat is combined and come plane on the facing-up X-axis nut seat, scrape some 12-16 point in every 25mm * 25mm scope;
4) take out location mandril and two fairleads, the X-axis ball screw of packing into, feed screw nut on the X-axis ball screw is inserted in the X-axis nut seat, ball screw bearing before and after reinstalling, join and beat two installation screws that connect with upper planker on the X-axis nut seat, evenly be screwed into two hold-down screws, join at last and beat X-axis nut seat two taper pin bottom outlets, two taper pins of packing into after finish reaming are by hand finished the X-axis ball screw installment work.
The present invention is simple in structure, easy to operate, use the present invention, employing comes the method for facing-up X-axis nut seat that the X-axis ball screw of numerically controlled lathe is installed by location mandril and fairlead, it is parallel with dovetail face with the plane of saddle to guarantee that rear X-axis ball screw is installed so that upper planker when seesawing the X-axis screw mandrel only bear axial force, motion is steadily, precision is high, and the life-span of screw mandrel also increases greatly simultaneously; Also reduced workman's assembling experience to the impact of production efficiency, allowed the new worker also can grasp rapidly operation skill, Effective Raise efficiency of assembling, guaranteed that numerically controlled lathe X-axis ball screw assembly precision meets the demands.
