Description
Technical field
The present invention relates to a kind of machine tool structure, especially a kind of lathe bed structure of lathe.
Background technology
The existing body of lathe bed mainly is that the assemblings such as guide rail by bearing both sides before and after bearing before main spindle box, lathe bed, base, the screw mandrel, screw mandrel rear support, the screw mandrel form; Bearing, screw mandrel rear support are normally through the difference casting before main spindle box, lathe bed, base, the screw mandrel; The back is carried out machining respectively to the datum level of each casting foundry goods and mating surface etc.; Through connection fixtures such as bolt and nuts lathe bed is connected on the base afterwards; Main spindle box is connected lathe bed one end, and bearing, screw mandrel rear support are connected the lathe bed other end before the screw mandrel, and assembling forms body of lathe bed structure.Adopt that several technical parameters are difficult to guarantee below the body of lathe bed that this mode makes: 1, the axiality of the bearing endoporus of the bearing endoporus of bearing, screw mandrel rear support before the screw mandrel; 2, the depth of parallelism of bearing axial line and screw mandrel front and back bearing two side rails before and after the screw mandrel; 3, the depth of parallelism of the spindle hole axis of bearing axial line and main spindle box before and after the screw mandrel.Even each part all meets the requirements after machining; But because the mating surface between bearing is processed respectively before and after the mating surface between mating surface, lathe bed and main spindle box between lathe bed and base, lathe bed and the screw mandrel; The positioning reference disunity also is prone to because tolerance build-up influences above-mentioned three important technological parameters after the assembling.Adopt each parts to assemble respectively to form the monoblock type body of lathe bed simultaneously, the quality of body of lathe bed structure also has substantial connection with assembly crewman's mounting technology level, very easily influences the precision of the assembling back body of lathe bed 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 integral type lathe lathe bed structure before and after the main spindle box of long service life, lathe bed, base, screw mandrel.
The present invention for realizing the technical scheme that above-mentioned purpose adopts is: bearing integral type lathe lathe bed structure before and after a kind of main spindle box, lathe bed, base, the screw mandrel; Comprise main spindle box, lathe bed, base, the preceding bearing of screw mandrel, screw mandrel rear support; Bearing, screw mandrel rear support are the integral type overall structure before the lathe bed of this body of lathe bed structure, base, the screw mandrel; Lathe bed is directly extended to form by the upside of base, and the bearing integral type is connected the upside of the forward end of lathe bed before the screw mandrel, and screw mandrel rear support integral type is connected the rear end of the preceding bearing of lathe bed upper screw rod; Bearing is provided with the preceding bearing endoporus that runs through the preceding bearing of screw mandrel before the screw mandrel; The screw mandrel rear support 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, and bearing and screw mandrel rear support both sides are respectively equipped with the guide rail that is directly extended to form by lathe bed before screw mandrel; Two guide rails are parallel to each other, and two guide rails also respectively with front and back bearing endoporus axis parallel.
The present invention for realizing the further technical scheme that above-mentioned purpose adopts is: the main spindle box integral type is connected the upside that lathe bed leans on the rear end; Bearing, screw mandrel rear support are the integral type overall structure before the main spindle box of this body of lathe bed structure, lathe bed, base, the screw mandrel; Screw mandrel rear support integral type is connected on the lathe bed position between the bearing before the main spindle box and screw mandrel; Main spindle box is provided with the spindle hole that runs through main spindle box, and front and back bearing endoporus axial line also is parallel to each other with the spindle hole axial line of main spindle box.
Bearing integral type lathe lathe bed structure is owing to main spindle box, lathe bed, base, the preceding bearing of screw mandrel, screw mandrel rear support are the integral type overall structure before and after the present invention's main spindle box, lathe bed, base, the screw mandrel; Bearing casts out together before and after the screw mandrel; Improved rigidity; The depth of parallelism of the depth of parallelism, front and back bearing endoporus axial line and the spindle hole axial line of bearing two side rails guarantees through machining respectively before and after axiality, front and back bearing endoporus axial line and the screw mandrel of front and back bearing endoporus; Avoided the trouble of split type installation adjustment; And guaranteeing that through manual work adjustment the human factor that exists influence assembly precision, the depth of parallelism, the front and back bearing endoporus axial line of bearing two side rails are all much high than split type structure precision with the depth of parallelism of spindle hole axial line before and after the axiality of front and back bearing endoporus, front and back bearing endoporus axial line and the screw mandrel; Simultaneously; Because bearing, screw mandrel rear support can effectively reduce the clamping times in the process for the integral type overall structure before main spindle box, lathe bed, base, the screw mandrel; Can effectively reduce tired and the body of lathe bed structural entity precision after the influence assembling of difference-product on business; Body of lathe bed structural entity precision is not subject to assembly crewman's mounting technology level affects yet; Therefore body of lathe bed structure 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; In addition; The formula overall structure makes body of lathe bed structural entity rigidity be enhanced because lathe bed, base are cast as one, and makes that the guide rail on the lathe bed is not yielding, improves the stability of guide rail; Body of lathe bed structural vibrations is also littler, can effectively improve the service life of body of lathe bed structure.
Below in conjunction with accompanying drawing and embodiment bearing integral type lathe lathe bed structure before and after main spindle box of the present invention, lathe bed, base, the screw mandrel is described further.
