Abstract

The invention relates to a pressing plate bearing supporting device on a machine tool sliding guide rail. The device comprises a pressing plate and is characterized by further comprising a needle bearing which is mounted on a shaft with rotational eccentricity, the other end of the shaft is fixed to a needle bearing support, and the needle bearing support is mounted on the pressing plate through mounting screws. The device resists overturning moment caused by gravity or cutting force and makes reasonable use of part of rolling motion to replace sliding motion, thereby effectively reducing the guide length of the pressing plate, saving space for a multi-shaft sliding guide rail numerically controlled lathe and making machine tool arrangement more reasonable; meanwhile, the motion precision of the moving shaft is improved, abrasion of a guide rail plastic sticking surface is reduced, and therefore the service life of a machine tool is prolonged; the quick moving speed of the moving shaft is increased, sliding and rolling are combined, and reliability and stability of machine tool running are improved.

Description

Pressing plate bearing support assembly on machine tool slide guide rail
Technical field
The present invention relates to machine tool slide guide rail, particularly relate 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 has been applied on various lathe, as common CA6140 lathe, numerically controlled lathes etc., its motion guide rail is all move realization by rail plate.
Along with industrial expansion, numerically controlled lathe is also in continuous renewal and the replacement, the operation of processing technology is constantly being concentrated, require that numerically controlled lathe is complicated constantly, the mobile number of axle constantly increases, due to the restriction of numerically controlled lathe integral arrangement or structure, cause the targeting part length of shifting axle constantly to shorten, can not instructions for use be met.Adding guide pass is laminating, can produce distortion after stressed, there will be hold-down plate surface and contacts uneven phenomenon, also affect machine tool accuracy and quick-reaction capability during motion.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, a kind of length that can shorten required for guiding is provided, meet instructions for use simultaneously, 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.
Technical scheme taked for achieving the above object is:
Pressing plate bearing support assembly on a kind of machine tool slide guide rail, comprise 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 mounting screw.
Described needle bearing support is also provided with trip bolt.
The axle jackscrew of described rotatable bias is fixed.
Machine tool slide guide rail clip bearing support assembly of the present invention, because having resisted the tilting moment because gravity and cutting force cause, so the guiding length of pressing plate effectively can be shortened, save space to the general layout of multiaxis rail plate numerically controlled lathe, lathe has been arranged more reasonable; Improve the kinematic accuracy of shifting axle simultaneously, decrease the wearing and tearing of laminating of guide rail, thus add lathe service life; And add the speed of shifting axle movement fast, slip and rolling are combined, improves lathe reliability of operation and stability.Needle bearing is arranged on the axle with bias, and the other end of this axle is fixed on needle bearing support, and the axle with bias utilizes the bias rotating adjustment axle can adjust the distance of needle bearing and guide rail, ensures that pressing plate and guide pass are in rational distance range.
Machine tool slide guide rail clip bearing support assembly of the present invention is applicable to, because being subject to gravity or the larger slip shifting axle of larger cutting force impact, also can being used in the quick movement of the rail plate moved in parallel simultaneously.
Accompanying drawing explanation
Fig. 1 is the pressing plate bearing support assembly application simplified schematic diagram on machine tool slide guide rail of the present invention;
Fig. 2 is the pressing plate bearing support device structure schematic diagram on machine tool slide guide rail of the present invention.
Detailed description of the invention
Pressing plate bearing support assembly on machine tool slide guide rail of the present invention is the improvement for the pressing plate on existing machine tool slide guide rail.Pressing plate on usual machine tool slide guide rail is exactly laminating common plane, and the pressing plate body in Fig. 1 is the same, needs certain length could carry cutting force and have guide function.As Fig. 2, pressing plate increases bearing support assembly, and it is connected with pressing plate body 5 by four mounting screws 2.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, and huge structure, frictional resistance is large, and too short, do not have guidance quality, kinematic accuracy is poor.Particularly when being subject to the restriction of the factors such as lathe overall structure, guidance quality and kinematic accuracy are more difficult to be guaranteed.For this reason, the present invention 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 located by keyway, and be connected with pressing plate body 5 by four mounting screws 2, needle bearing support 6 and pressing plate body 5 are linked into an integrated entity.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 the axle of bias, makes changing with the gap of guide rail.After when between needle bearing 1 and guide rail, gap is adjusted to and is needed numerical value, fastening 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 generally exists with grouped aspect, therefore pressing plate bearing support assembly of the present invention also uses in groups.As shown in Figure 1, because structure restriction employs two groups of totally 4 these devices, in figure simultaneously: 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.
