Description
Technical field
The present invention relates to a kind of parts of numerically controlled lathe, especially a kind of skateboard of numerically controlled lathe.
Background technology
The skateboard (being also referred to as saddle or longitudinal slide) of existing numerically controlled lathe mainly is made up of the guide rail of bearing both sides before and after bearing, screw mandrel rear support, feed screw nut's seat, the screw mandrel before slide plate main body, motor cabinet, the screw mandrel; Bearing, screw mandrel rear support, feed screw nut's seat are normally through the difference casting before slide plate main body, motor cabinet, the screw mandrel; The back is carried out machining respectively to the datum level of each casting foundry goods and mating surface etc.; Afterwards through connection fixtures such as bolt and nut with motor cabinet, screw mandrel before bearing, screw mandrel rear support, feed screw nut's seat be connected on the slide plate main body, assembling forms skateboard.Adopt that several technical parameters are difficult to guarantee below the skateboard that this mode makes: 1, the axiality of the bearing endoporus of the bearing endoporus of bearing and screw mandrel rear support before the screw mandrel; 2, the depth of parallelism of bearing endoporus axial line and screw mandrel front and back bearing two side rails before and after the screw mandrel; 3, the perpendicularity of the interior axially bored line of bearing endoporus axial line and feed screw nut's seat before and after the screw mandrel.Even each part meets the requirements after machining, but owing to adopt the split-type structural parts more, and each parts mechanical processing and positioning benchmark disunity, also be prone to after the assembling because tolerance build-up influences above-mentioned three important technological parameters.Adopt each parts to assemble the formation skateboard respectively simultaneously, the quality of skateboard also has substantial connection with assembly crewman's mounting technology level, very easily influences the precision of assembling tail skid structure because of human factor.
Summary of the invention
The purpose of this invention is to provide that a kind of precision height, good rigidly, vibration are little, bearing, feed screw nut's seat integral type skateboard before and after the motor cabinet of long service life, screw mandrel.
The present invention for realizing the technical scheme that above-mentioned purpose adopts is: bearing, feed screw nut's seat integral type skateboard before and after a kind of motor cabinet, the screw mandrel; Comprise slide plate main body, motor cabinet, the preceding bearing of screw mandrel, screw mandrel rear support, feed screw nut's seat; Bearing, screw mandrel rear support, feed screw nut's seat are the integral type overall structure before the slide plate main body of this skateboard, motor cabinet, the screw mandrel; Bearing and screw mandrel rear support are extended upward by slide plate body front end and rear end respectively and form before the screw mandrel; The bearing middle part is provided with the preceding bearing endoporus that runs through the preceding bearing of screw mandrel before the screw mandrel, and screw mandrel rear support middle part is provided with the rear support endoporus that runs through the screw mandrel rear support, and preceding bearing endoporus is coaxial with the rear support endoporus; The motor cabinet integral type is connected the outside of the preceding bearing of screw mandrel; Bearing and screw mandrel rear support both sides are respectively equipped with the guide rail that is directly extended to form by the slide plate main body before screw mandrel, and two guide rails are parallel to each other, and two guide rails also respectively with front and back bearing endoporus axis parallel; Feed screw nut's seat is extended to form downwards by the middle part of slide plate main body, and the axis of feed screw nut's seat endoporus is vertical each other with front and back bearing endoporus axial line.
The present invention for realizing the further technical scheme that above-mentioned purpose adopts is: said motor cabinet is provided with the motor cabinet endoporus that runs through motor cabinet, and the motor cabinet endoporus is coaxial with preceding bearing endoporus.
Bearing, feed screw nut's seat integral type skateboard are owing to slide plate main body, motor cabinet, the preceding bearing of screw mandrel, screw mandrel rear support, feed screw nut's seat are the integral type overall structure before and after the present invention's motor cabinet, the screw mandrel; Bearing, screw mandrel rear support, feed screw nut's seat cast out together before slide plate main body, motor cabinet, the screw mandrel; Improved integral rigidity; Make that the guide rail on the slide plate main body is not yielding; Improve the stability of guide rail, the vibration of skateboard is also littler, can effectively improve the service life of skateboard; The perpendicularity of axially bored line and front and back bearing endoporus axial line guarantees through machining respectively in the depth of parallelism of the axiality of front and back bearing endoporus, the depth of parallelism, two guide rails and the front and back bearing endoporus axial line of two guide rails, the feed screw nut's seat; Precision guarantees easily; Avoided the trouble of split type installation adjustment; Because the positioning reference of the machining of integral type skateboard is identical, the precision of the split type skateboard of integral type skateboard ratio of precision that processes is high a lot of in addition; Simultaneously; Because bearing, screw mandrel rear support, feed screw nut's seat can effectively reduce the clamping times in the mechanical processing process for the integral type overall structure before slide plate main body, motor cabinet, the screw mandrel; Can effectively reduce tired and the skateboard overall precision after the influence assembling of difference-product on business; The skateboard overall precision is not subject to assembly crewman's mounting technology level affects yet; Therefore skateboard precision of the present invention is high, and can reduce the assembling man-hours requirement and shorten life cycle of the product, also reduces the cost that is produced because of assembling.
Below in conjunction with accompanying drawing and embodiment bearing, feed screw nut's seat integral type skateboard before and after motor cabinet of the present invention, the screw mandrel are described further.
