Description

A kind of rigidity of toppling greatly directly turns platform
Technical field
The present invention relates to the one kind in digital control processing field is toppled greatly, rigidity directly turns platform.
Background technology
Turntable plays important effect in digital control processing.But current turntable there are problems with:1. it is common to turn It is 1/2~2/3 position of rotating disk radius that platform requires that card supports radius (usually rotary shaft radius).If less than this model Enclose, then what card was carried topple, and rigidity is bad, and when making operating, the upper and lower slight oscillatory in card edge, causes the workpiece meeting for processing There is obvious knife mark, surface smoothness is bad.2. common turntable improves the rigidity of toppling of its rotary table top with combination bearing, but The axial space that combination bearing takes is larger, needs to increase considerably turntable height, this processing limited to processing center machine tool It is unfavorable for space, because this can tie up the processing space of machine Z-axis, affects the Z axis stroke of cutter.And combination bearing Price is significantly larger than angular contact bearing, high cost.
The content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of rigidity of toppling greatly directly turns platform;Which not only can be significantly The bearing capacity and rigidity of toppling of loading floor are improved, and the stationarity of machining accuracy and turntable operating can also be improved.
In order to achieve the above object, a kind of rigidity of toppling greatly of the present invention directly turns platform, mainly includes:
Body, is equiped with motor stator, rotor in the body from outside to inside successively, bearing block, is installed in bearing Shaft bearing, rotary shaft on seat, outer ring and the bearing block of the shaft bearing make interference fit, inner ring and the rotation of shaft bearing Interference fit is made in rotating shaft;
Spring bearing, the spring bearing are installed on bearing block, and the outer ring of the spring bearing, inner ring are corresponded to and axle respectively Bearing, rotary disk make slight interference cooperation, to prevent spring bearing radial-play;
Rotary disk, the rotary disk are installed in the top of body, and the rotary disk is installed on the rotary shaft by screw, and The rotary disk is also locked on spring bearing by adjusting screw;
Encoder, the encoder are installed on body.
Preferably, the bearing gland of the outer ring for clamping shaft bearing, the bearing are equiped with above the shaft bearing Gland passes through screw lock.
Preferably, it is equiped with below the shaft bearing for locking the locking nut of the inner ring of shaft bearing.
Preferably, rotating seal ring is additionally provided with above the shaft bearing.
Preferably, bearing spacer is equiped with the shaft bearing, the shaft bearing and bearing spacer are installed in rotation On axle.
Preferably, the encoder is installed on body by encoder mounting seat.
During adjustment, beaten on the card edge of rotary disk with amesdial contact, slowly rotate rotary disk, by adjusting one by one Adjusting screw, carries out pretension, and observes amesdial pointer to spring bearing, until rotating one week, the pointer of table no longer change or Till changing in allowed limits.Then the edge of rotary disk is withstood on thrust meter, applies certain axial force, the pointer of table Still constant or variation is qualified in allowed limits, and now turntable adjustment is completed.
When placing workpiece in card, or when during processing, cutter is acted on workpiece, load is just by rotary shaft and spring bearing Shared, due to the effect of spring bearing, improves the bearing capacity and resistance to capsizing of card.Ensure card fortune during processing Row is steady, it is therefore prevented that disk tilt.Especially when workpiece center of gravity not center in rotary disk or cutter is carried out at the edge of card When axial plane is processed, the advantage of this kind of structure just becomes apparent from embodying.
This structure is applied on Digit Control Machine Tool, is used as the 4th axle of lathe, is expanded card, in processing large-scale workpiece The machining accuracy for ensureing workpiece to be machined can be used when (reaching or in rotary disk diameter certain limit), that is, expanded and added The size range of work workpiece.And, this structure also add the bearing capacity of card and rigidity of toppling, it is ensured that card operating, Stationarity when detection or processing, improves the reliability of turntable.
Description of the drawings
Fig. 1 is the cross section structure diagram of the present invention;
Fig. 2 is work pieces process schematic diagram of the present invention.
Wherein, 1 is body, and 2 is motor stator, and 3 is rotor, and 4 is shaft bearing, and 5 is bearing spacer, and 6 is bearing Seat, 7 is spring bearing, and 8 is adjusting screw, and 9 is rotary disk, and 10,14 is screw, and 11 is rotary shaft, and 12 is rotating seal ring, 13 For bearing gland, 15 is locking nut, and 16 is encoder mounting seat, and 17 is encoder, and 18 is cutter, and 19 is workpiece.
Specific embodiment
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, apparent clearly defines so as to make to protection scope of the present invention.
With reference to Fig. 1~2, a kind of rigidity of toppling greatly of the embodiment of the present invention directly turns platform, mainly includes:
It is equiped with motor stator 2, rotor 3 in body 1, the body 1 from outside to inside successively, bearing block 6, is installed in Shaft bearing 4, rotary shaft 11 on bearing block 6, outer ring and the bearing block 6 of the shaft bearing 4 make interference fit, shaft bearing 4 inner ring makees interference fit with rotary shaft 11;
Spring bearing 7, the spring bearing 7 are installed on bearing block 6, and the outer ring of the spring bearing 7, inner ring are corresponded to respectively Slight interference cooperation is made with bearing block 6, rotary disk 9 in ground, to prevent 7 radial-play of spring bearing;
