Boring machine with the aobvious device of winding number
The utility model relates to a kind of boring machine, relates in particular to a kind of boring machine with the aobvious device of winding number, belongs to boring machine technical field.
Boring machine is a kind of lathe that boring is carried out in the existing hole of workpiece with boring cutter, uses different cutters and annex also can carry out drilling, milling, screw thread and processing excircles and end face.Conventionally, boring cutter rotates to be main motion, and the movement of boring cutter or workpiece is feed motion; Be mainly used in machining high-precision hole or one-time positioning and complete the fine finishining in a plurality of holes.
Current boring machine, especially T68 boring machine, as shown in Figure 1 and Figure 2, it comprises centration axis 101, alignment bearing 102 and rotary table 103 to its structure, shown in centration axis 101 be a solid shafting.There are following problems in this T68 boring machine:
1, the revolution of workbench location, can only guarantee by range estimation scale, position error is larger;
2,, in working angles, whether workbench produces swing offset due to the effect of cutting force, cannot monitor in real time;
3, digital display rule, without redundant space, cannot be installed in workbench inside.
The deficiency of above three kinds of design defect, can not be guaranteed work table rotation precision, has had a strong impact on crudy.
Utility model content
The purpose of this utility model is: a kind of boring machine with the aobvious device of winding number is provided, solve current boring machine especially T68 boring machine due to the deficiency of inner space, digital display rule cannot be installed, cause work position error larger, and the technical problem that cannot monitor in real time, thereby can effectively solve above-mentioned problems of the prior art.
The purpose of this utility model is to realize by following technical proposals: a kind of boring machine with the aobvious device of winding number, comprise centration axis and synchronous inductor, centration axis top is rotary table, establishes a pallet with screw rod above centration axis, and the end of screw rod is placed in centration axis; On the table top of rotary table, establish the recessed groove of a circle, the datum level as synchronous inductor is installed is provided with plane pallet on datum level; Synchronous inductor comprises synchronous inductor rotor and synchronous inductor stator, described synchronous inductor stator is fixed by No. two screws and pallet, synchronous inductor rotor is fixed by screw and plane pallet, and synchronous inductor rotor rotates with rotary table; Between described synchronous inductor rotor and synchronous inductor stator, be provided with gap 0.2mm.
As a kind of optimal way, the original thread hole bottom outlet of centration axis drills formation threaded bore, and from root horizontally set one aperture of centration axis, the cable of described synchronous inductor stator is connected to the amplifier of workbench outside by threaded bore and aperture.
As a kind of optimal way, the end of screw rod is placed in the threaded bore of centration axis.
As a kind of optimal way, in the outside of pallet, add a protective cover.
As a kind of optimal way, on the non-working surface of synchronous inductor rotor inner ring, synchronous inductor stator outer ring, process respectively four M4 screws, and install respectively four additional for regulating the M4 holding screw in gap.
Further preferably, described gap is 0.2mm.
In the utility model, the effect of part is as follows:
Threaded bore and aperture: centration axis is non-rotary at work, the screw in centration axis is lathe original structure, only the bottom outlet of former screw need be drilled.The aperture of laterally processing, the screw rod of centering pallet is hollow, communicates with the hole at centration axis center.Synchronous inductor stator lead successively by the centering hole at pallet center, the hole at centration axis center and laterally aperture pass, be connected to external amplifier, avoid lead-in wire to be wound around.
Pallet: the fixing pallet band screw rod of synchronous inductor stator, on pallet, there is the fixedly hold-down screw of synchronous inductor stator, be also useful on the holding screw that regulates stator and rotor clearance.When excesssive gap between stator and rotor, unclamp hold-down screw, tighten holding screw, stator is pushed up downwards, to reduce the gap between stator and rotor, screw lock is finally tightened.
Plane pallet: fixing synchronous inductor rotor, on pallet, there are four hold-down screws outer ring, inner ring has four holding screws, when on synchronous inductor rotor, plane and work table rotation plane are not parallel, unclamp hold-down screw, by tightening holding screw, regulate the depth of parallelism, screw lock is finally tightened.
Datum level: mounting plane pallet use, adds man-hour datum level parallel with plane of rotation.
Synchronous inductor: synchronous inductor is comprised of rotor and stator two parts, the winding of its surface distributed, it is not identical that the winding of stator and rotor distributes.When stator and relative rotation of rotor, due to electromagnetic coupled effect, mechanical displacement can be transformed into the signal of telecommunication, pass to digital display meter and demonstrate corner displacement amount.
Compared with prior art, the beneficial effects of the utility model: the utility model boring machine structure, can overcome the narrow and small shortcoming in workbench inner space, successfully digital display device is attached in lathe, improve the accuracy of work table rotation positioning precision and calibration, improve the machining accuracy of lathe, enhance productivity, be particularly useful on T68 horizontal boring machine.
