To moving up and down, actually moving direction is identical with the second slide rail 22, only because the 3rd slide rail is shorter than the second slide rail 22, because
This, mobile scope and distance is shorter than second slide rail 22, but synthesis realizes the position of the emery wheel in the vertical direction
Adjustment, that is, Z-direction, furthermore, the present invention realizes the emery wheel 33 can in the horizontal direction, and perpendicular to the first slide rail
5th, the direction of the second slide rail 22 and the 3rd slide rail, according to rectangular coordinate system in space, then can be defined as Y direction.Cumulated volume
From the point of view of the mechanism of invention, pass through the cooperation of the work system 2 and the column and grinding head system, when processing workpiece, base
It can realize and process at any angle on this.
A kind of processing method of the tip tap-grinding machine provided with reference to Fig. 1-9, the present invention, including:
Workpiece 40 is placed in fixture 41 by original state, origin position, the remote cylinder 42 specifically fixed
In fixture 41, now, the proximity transducer 39 can sense the workpiece 40, and the proximity transducer 39 is fed back signal to
The cylinder 42, the cylinder 42 promotes the movable part of fixture 41, the fixture 41 is clamped the workpiece 40.
First servomotor 11 drives the first ball-screw 13, drives first sliding block 6, workbench supporting plate 7 and described
Workbench 9 is moved so that the workpiece reaches the first specified location, and first specified location refers in X to specified location.
According to the angle of grinding workpiece 40, then indexing headstock 8 is adjusted, fixed because indexing headstock 8 and the bolt of workbench 9, from
And reach the angle of adjustment workbench.
Then the second servomotor 17 directly drives the second ball screw 20, causes whole bistrique part descending, according to work
The height of part 40, sets the rotating cycle of the 3rd servomotor 24, is the descending distance of the 2nd 28 amendment supporting plate, reaches Z-direction workpiece
During 40 grinding height, the 3rd servomotor 24 drives the 3rd ball screw 26, and the second amendment supporting plate 28, which is gone downwards to up to second, specifies
Position.Trickle adjustment emery wheel 33 arrives the height of workpiece 40.Synchronous motor 46 drives active synchronization belt wheel 43 to rotate, and passes through timing belt
44, drive driven synchronous pulley 45 to rotate, so that the 4th ball screw 30, emery wheel 33 is along the 4th line slide rail 31 to forerunner
It is dynamic, reach the 3rd specified location that grinding workpiece is specified, i.e. Y-direction a specified location.Emery wheel 33 starts to be ground workpiece, processing
After the completion of, each part returns to origin position.Cylinder 42 bounces back, and unclamps workpiece 40, takes out workpiece.
Conventional start-up circuit is also replaced by variable-frequency control technique by the present invention, and with frequency converter stepless speed regulation, soft start, perseverance turns
Square output greatly meets machining equipment to constant speedpump, permanent torque requirement.
Compared with prior art, technical scheme has advantages below;
Tip tap-grinding machine described in the technical program is laid out using turntable type, and Rotary cloumn can rotate, and workbench is realized
Indexing, expands the grinding machine range of work, improves processing efficiency;Also, using emery wheel rotation, workpiece translation, using dove-tail form bottom
Seat and workbench coordinate, and workbench is compact using stacked structure, can bear the larger grinding force produced during corase grind, again can
Ensure high accuracy during finishing, rigidity increase, while thermal deformation is small, efficiency is improved, qualification rate increase.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, are not departing from this
In the spirit and scope of invention, it can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
The scope of restriction is defined.
