In addition, the tap breakage detecting means 400 is installed at each position where the tab T is provided.

Referring to the operation relationship between the tap breakage detection device according to the present invention configured as described above and the tapping processing device using the same in detail as follows.

11 is a view showing the working relationship of the tapping processing apparatus according to the present invention.

First, in order to perform tapping on the workpiece W produced by other work processes such as a press, a separate workpiece W is supplied to the upper seating groove 216 of the guide plate 214 using a supply means (not shown). The workpieces W are supplied to be seated one by one. In this case, the workpieces W are supplied by installing a supply unit in a direction in which the horizontal cylinder 232 is provided.

In this way, after being seated in the seating groove 216 of the guide plate 214 is moved in the opposite direction to which the workpiece (W) is supplied.

That is, when the workpiece (W) is seated in the seating groove 216 of the guide plate (2) 1 when the vertical cylinder 204 is operated, the vertical slide body 222 is raised to the top, When the vertical slide 222 rises upward, the workpiece W is seated in the seating groove 229 formed in the auxiliary plate 228 of the horizontal slide body 225. Lifted from the top.

As described above, when the workpiece W seated in the seating groove 216 of the guide plate 214 is fitted into the seating groove 229 of the horizontal slide body 225 and then the horizontal cylinder 232 is operated, The horizontal slide body 225 reaches the position of the neighboring seating groove 216 of the seating groove 216 of the guide plate 214, and then operates the vertical cylinder 204 to operate the vertical slide body 222 again. When lowered, the workpiece W seated on the upper side of the horizontal slide body 225 is seated in the seating groove 216 of the guide plate 214 again.

As such, the workpiece W seated in the seating groove 229 of the horizontal slide body 225 is seated in the seating groove 216 of the guide plate 214, and then the horizontal cylinder 232 is operated to operate the horizontal slide body. When the 225 is returned to its original position, the workpiece W is completed to move to the seating groove 216 of the neighboring guide plate 214.

As such, the workpiece W is sequentially moved in a manner of being seated in the neighboring seating grooves 216 by the upward and downward movement of the vertical slide body 222 and the horizontal reciprocating motion of the horizontal slide body 225. do.

At this time, according to the installed number of the tapping means 300 and the number of the workpiece (W) is supplied at the same time a plurality of, the movement of the workpiece (W) is also supplied to the workpiece (W) As much as the seating groove 216 is skipped to move to the seating groove 216 of the next compartment.

When the workpiece (W) moved in one direction by the above operation is located in the tapping means 300 is a tapping operation is performed on the workpiece (W).

That is, when the motor 336 is operated, the tab T rotates in one direction, and in this state, the workpiece W is supplied and the tapping means 364 operates the lifting and lowering cylinder 364. 300) the whole is raised and lowered, and the tap T causes the tapping of the workpiece W by the lifting and lowering operation.

At this time, the tapping operation is performed while passing through the through-hole formed in the workpiece (W), in this process the tab (T) is lowered, the magnetic properties of the tab (T) when positioned inside the hole (212) The magnet 416 of the tap breakage detecting means 400 is pulled out of the tube tube 412 by the force and is attached to the tab T.

As such, when the magnet 416 is attached to the tab T, the guide shaft 414 in contact with the proximity sensor 424 falls and attaches to the tab T in the form of pressing the elastic member S. Will be.

On the contrary, when the tab T rises, the guide shaft 414 contacts the proximity sensor 424 by the elastic force of the elastic member S while the magnet 416 falls from the tab T. .

In addition, when the tab T is broken during the operation, the guide shaft 414 of the tap breakage detecting means 400 does not operate.

Therefore, while performing the tapping operation using the tap T, the detachable operation of the proximity sensor 424 is detected by the repeated operation of the guide shaft 414 to determine whether the tap T is broken. .

That is, when the tab T is not broken, the guide shaft 414 is detachably attached and detached from the proximity sensor 424 in order to repeatedly move up and down the tab T. When the tab T is broken, the tab Regardless of whether the T rises or falls, the guide shaft 414 is always attached to the proximity sensor 424.

Therefore, when the tap (T) is broken, this information is sent to the control unit 500, and the control unit 500 receives the information, the tapping processing device so as to prevent any further failure of the workpiece (W) anymore. All operation of (10) is stopped.

As such, when the tapping moving device 10 is stopped and the tap T is replaced with another to process the tapping processing device 10, the tapping operation is performed.

As described above, the workpiece W having a tapping operation is moved in the opposite direction to which the workpiece W is supplied by the organic operation of the vertical slide body 222 and the horizontal slide body 225 of the moving means 200 and discharged. Will be.

12 is an enlarged perspective view of a main portion showing another embodiment of the tap breakage detecting means according to the present invention, and FIG. 13 is an enlarged cross-sectional view of the main portion of FIG.

As shown in the figure, the tap breakage detecting means 600 is provided with a contact portion 610 which contacts the tab T when the tab T is lowered and positioned in the hole 212.

Here, the contact portion 610 is provided with a bush 612 fastened and fixed to the lower portion of the guide plate 214 provided in the front, rear of the hole 212, the hole (outer) on the outer peripheral surface of the upper end of the bush 612 The elastic plate 614 is fixed by the fixing means so as to be positioned at 212.

Furthermore, the sensing unit 620 is installed on the same line of the contact unit 610 to detect breakage of the tab T by the operation of the contact unit 610.

In addition, the sensing unit 620 is provided with a proximity sensor 622 that is fitted to the bush 612 to be fixed to face the outer direction of the hole 212.

The operation relationship with respect to the tap processing apparatus of the present invention configured as described above is made by the same method as in the former, and will be omitted here.

However, when the tab T descends into the hole 212, the tab T descends while pressing the upper portion of the elastic plate 614, and the proximity sensor is pressed by the pressing force of the tab T of the elastic plate 614. Contact 622.

On the contrary, when the tab T rises, the pressing force to press is released and the elastic plate 414 returns to its original shape, thereby being separated from the proximity sensor 622.

In this case, when the tab T is lowered in a damaged state, the upper portion of the elastic plate 414 may not be pressed, so that the elastic plate 614 contacts the proximity sensor 622 even when the tab T is lowered. This information makes it possible to know the damaged state of the tab T.

In the above, a preferred embodiment of a tap breakage detecting device and a tap processing device using the same according to the present invention have been described. It is possible to carry out various modifications and this also belongs to this invention.

The present invention relates to a tap breakage detection device and a tap processing device using the same, and more particularly, to detect the breakage of the tap when the tap operation on the workpiece and to stop the tap processing device at the same time to prevent mass production of defective products It relates to a tap breakage detection device and a tap processing device using the same.
