Abstract
The utility model relates to a plate shaft on lathe sliding guide holds strutting arrangement, including the clamp plate body, its characterized in that still includes bearing, but bearing installs and is having the epaxial of rotate eccentric, and this the other end is fixed on the bearing support, the bearing support passes through mounting screws and installs on the clamp plate. The utility model discloses a device is because of having resisted because the overturning moment that gravity or cutting force caused, and the rational utilization part is rolled the motion and is replaced sliding motion, so can effectively shorten the direction length of clamp plate, has practiced thrift the space for multiaxis sliding guide numerical control lathe's general layout, and it is more reasonable that messenger's lathe is arranged, improve the movement accuracy who removes the axle simultaneously, reduced the wearing and tearing that the face was moulded in the guide rail subsides to lathe life has been increased, and increased the speed that moves the axle quick travel, and make slip and roll combine together, improved lathe reliability of operation and stability.
Description
Technical field
This utility model relates to machine tool slide guide rail, particularly relates to the pressing plate bearing support assembly on a kind of machine tool slide guide rail.
Background technology
During lathe is manufactured, the motion of each axle of lathe is all realized by rolling guide or rail plate, and wherein rail plate has used production for many years and to be applied on various lathe, such as common CA6140 lathe, numerically controlled lathes etc., its motion guide rail is all to move realization by rail plate.
Along with industrial expansion, numerically controlled lathe is also being constantly updated and is being regenerated, the operation of processing technique is constantly being concentrated, require that numerically controlled lathe complicates constantly, the mobile number of axle is continuously increased, due to numerically controlled lathe integral arrangement or the restriction of structure, the targeting part length of shifting axle is caused constantly to shorten, it is impossible to meet and use requirement.Adding guide pass is laminating, can be deformed after stress, there will be the phenomenon that hold-down plate surface contact is uneven, also affect machine tool accuracy and quick-reaction capability during motion.
Summary of the invention
The purpose of this utility model is to overcome the defect of above-mentioned prior art, a kind of length that can shorten required for guiding is provided, meet simultaneously and use requirement, save space to the general layout of multiaxis rail plate numerically controlled lathe, make lathe arrange more reasonably machine tool slide guide rail clip bearing support assembly.
The technical scheme taked for achieving the above object is:
A kind of pressing plate bearing support assembly on machine tool slide guide rail, including pressing plate body, characterized by further comprising needle bearing, described needle bearing is arranged on the axle with rotatable bias, the other end of this axle is fixed on needle bearing support, and described needle bearing support is arranged on pressing plate by installing screw.
It is also equipped with trip bolt on described needle bearing support.
The axle jackscrew of described rotatable bias is fixed.
This utility model machine tool slide guide rail clip bearing support assembly, because having resisted the tilting moment caused due to gravity and cutting force, so the guiding length of pressing plate can effectively be shortened, save space to the general layout of multiaxis rail plate numerically controlled lathe, made lathe arrange more reasonable；Improve the kinematic accuracy of shifting axle simultaneously, decrease the abrasion of laminating of guide rail, thus add lathe service life；And add the speed that shifting axle quickly moves, make slip and rolling combine, improve lathe reliability of operation and stability.Needle bearing is arranged on on eccentric axle, and the other end of this axle is fixed on needle bearing support, utilizes the bias rotating adjustment axle can adjust the distance of needle bearing and guide rail with eccentric axle, it is ensured that pressing plate and guide pass are in rational distance range.
Machine tool slide guide rail clip bearing support assembly of the present utility model is suitable for because being affected bigger slip shifting axle by the cutting force of gravity or bigger, and the quick of rail plate that simultaneously can be used with moving in parallel is moved.
Accompanying drawing explanation
Fig. 1 is the pressing plate bearing support assembly application simplified schematic diagram on this utility model machine tool slide guide rail；
Fig. 2 is the pressing plate bearing support device structure schematic diagram on this utility model machine tool slide guide rail.
Detailed description of the invention
Pressing plate bearing support assembly on this utility model machine tool slide guide rail, is the improvement for the pressing plate on existing machine tool slide guide rail.Generally the pressing plate on machine tool slide guide rail is exactly laminating common plane, as the pressing plate body in Fig. 1 is the same, needs certain length could carry cutting force and have guide function.Such as Fig. 2, pressing plate increases bearing support assembly, and it is installed screw 2 by four and is connected with pressing plate body 5.Relative sliding portions on pressing plate body 5 carries out laminating process, and as a rule, the length of pressing plate is restricted and requires, oversize, huge structure, and frictional resistance is big, the shortest, does not has guidance quality, and kinematic accuracy is poor.Particularly when being limited by factors such as lathe overall structures, guidance quality and kinematic accuracy are more difficult to be guaranteed.For this, this utility model realizes by improving pressing plate body 5, concrete improved procedure is: install needle bearing support 6 in one end of pressing plate body 5, this needle bearing support 6 is positioned by keyway, and be connected with pressing plate body 5 by four installation screws 2 so that needle bearing support 6 links into an integrated entity with pressing plate body 5.Needle bearing 1 is arranged on the axle 4 with rotatable bias, and the other end of the axle 4 of rotatable bias is fixed on needle bearing support 6, and when the axle of rotating eccentricity, needle bearing 1 moves up and down along with eccentric axle so that changing with the gap of guide rail.After gap is adjusted to need numerical value when between needle bearing 1 and guide rail, fasten trip bolt 3.
Described machine tool guideway moves, and precision all at more than 0.01mm, so the offset of the axle of bias is not too large, enough uses at 0.2-0.3mm.
During use, because rail plate typically exists with grouped aspect, therefore pressing plate bearing support assembly of the present utility model uses the most in groups.As it is shown in figure 1, be simultaneously used two groups of totally 4 these devices, in figure owing to structure limits: 11, pressing plate bearing support assembly X, 5-1, pressing plate body Y, 12, pressing plate bearing support assembly Y, 5-2, pressing plate body X, 9, rail plate X, 10, rail plate Y, 7, gliding mass X, 8, gliding mass Y.When gliding mass X7 and gliding mass Y8 moves simultaneously, 4 corresponding devices play a role.When gliding mass X7 moves on rail plate X9, the pressing plate body X being provided with pressing plate bearing support assembly X11 works；When gliding mass Y8 moves on rail plate Y6, the pressing plate body Y being provided with pressing plate bearing support assembly Y12 works.
