Description

Vibration Mechanism for Numerical Control Multiprocessing Machines {Vibration isolation device for Numerical Control composition processing machine}

The present invention relates to an anti-vibration mechanism for a numerically controlled multi-task machine, and more particularly, to an anti-vibration mechanism for a numerically controlled multi-task machine which is installed to prevent sagging or vibration of the workpiece when the workpiece rotates.

In general, the numerically controlled multi-task machine precisely controls the movement of the cutting tool and the workpiece by a program to precisely cut the workpiece.

As described above, the numerically controlled multi-task machine is capable of cutting larger workpieces while improving its function by increasing the size and precision.

When the workpiece was relatively short, it was fixed alone to the chuck. When the workpiece was longer or heavier, the workpiece was fixed to the chuck and the workpiece was supported by a tailstock on the opposite side of the chuck.

In addition, when the workpiece becomes larger and heavier, a dustproof mechanism is installed in the middle of the workpiece to support the workpiece.

As an example of the above-mentioned dustproof mechanism, a hydraulic dustproof opening in which a pair of guide rollers are retracted or opened by a hydraulic action is widely used.

The above-mentioned conventional dustproof mechanism will be described in more detail with reference to FIG. 1.

1 is an exemplary view for explaining a conventional dustproof mechanism.

Although not specifically shown, NC lathes or turning machines, among numerically controlled multi-task machines, have a workpiece set on the chuck of the main shaft and a tailstock arranged on the side facing the chuck, and a tool stand mounted on the outside of the workpiece. The workpiece is supported by and the chuck rotates at high speed to rotate the workpiece and the workpiece is cut by a cutting tool such as a bite mounted on a tool post.

In this case, the longer the workpiece, the more vibration may be generated, and the vibration may be difficult to precisely process the workpiece, thereby damping the vibration by using a dustproof mechanism.

Numerical control multi-task machine, etc. T groove 11 is formed on the upper side of the bed 10, and the saddle 20 is installed on the upper side of the bed (10).

The above-mentioned T-groove 11 is provided with a transfer table 30. A guide 31 is formed at the lower side of the transfer table 30, and the guide 31 is fitted into the above-described T-groove 11 to transfer the transfer table ( 30 is linearly moved in bed 10.

In addition, one side of the transfer table 30 is provided with a traction bar 32 which is extended / contracted by hydraulic pressure, and the traction bar 32 is pressurized to the side of the saddle 20 described above. 30 may be tied to the saddle 20.

In addition, the hydraulic dustproof opening 40 is provided above the transfer table 30, and the hydraulic dustproof opening 40 has a plurality of first guide rollers 41 and a second guide roller 42 disposed at the center thereof. ), And the plurality of first guide rollers 41 are opened or closed by a hydraulic action.

The workpiece 100 is supported at three points by the plurality of first guide rollers 41 and the second guide rollers 42, and when the workpiece 100 rotates, the plurality of first guide rollers 41 and the second guides are rotated. The rollers 42 rotate together to prevent the workpiece 100 from vibrating randomly.

The conventional dustproof mechanism configured as described above has the following problems.

In order to move the dustproof mechanism, the traction bar 20 is advanced by hydraulic action to bind to the saddle 20, and the saddle 20 drives the Z-axis feed system so that the saddle 20 pulls the carriage 30. Move it.

In addition, as the workpiece 100 is processed, the shape of the workpiece 100 gradually changes, and a position where vibration occurs in the workpiece 100 is changed, and in this case, it is necessary to move the dustproof mechanism.

However, the conventional antivibration mechanism has a problem in that the position of the antivibration mechanism cannot be moved while the workpiece 100 is being processed.

That is, to move the vibration isolator necessarily stops the cutting process for a while and by moving the saddle 20 indirectly moves the vibration isolator to a desired position, thereby causing a problem that the machining cycle time is delayed.

In addition, the above-mentioned conventional dustproof mechanism is always limited depending on the movement of the saddle 20, so that there is a problem that the dustproof mechanism cannot be moved to an independent position, and especially when the workpiece is a long and thin material, about halfway or vibration is There is a problem that the vibration isolator can not be moved arbitrarily to a position where there is a lot of possibility to occur.

In addition, in the case of the manual dustproof mechanism, since the effort to loosen the clamp bolt when moving the position, and then tighten the clamp bolt again, there is a problem of increasing the fatigue of the operator.

Therefore, the technical problem to be achieved by the present invention is to automatically transfer the dust-proof mechanism that can prevent vibration when processing a long length of material, and in particular to enable an independent position to increase the processing time and operation convenience The present invention aims to provide a dustproof mechanism for a numerically controlled multi-task machine that can reduce worker fatigue.

The technical problem to be achieved by the present invention is not limited to the technical problem mentioned above, another technical problem that is not mentioned can be clearly understood by those skilled in the art from the following description. There will be.

In addition, a dog; is further disposed on one side of the main block, a switch for detecting the dog on one side of the tailstock; may be arranged to stop the driving of the servomotor when the switch is closed.

Specific details of other embodiments are included in the detailed description and the drawings.

The dustproof mechanism for the numerically controlled multi-task machine according to the embodiment of the present invention made as described above can automatically transfer the dustproof mechanism, and in particular, can be independently transferred during cutting, and is independent of a specific position designated by a user. Position is possible.

In addition, the free movement of the vibration isolator improves the processing time and convenience of operation of the workpiece, thereby reducing the fatigue of the operator.
