Tapping machine tapping device

This creation is a tapping machine tapping device, especially a tapping machine tapping device suitable for tapping non-hex nuts.

According to the general tapping machine, when the hex nut tapping process is performed, the workpiece to be tapped is usually arranged through the whole material mechanism, and then falls to the front end of a feeding mechanism, and then pushed by the feeding mechanism to make the hexagon The nut is embedded in the groove with a V-shaped cross section on both sides. When the hex nut is locked by the card, the arc can be rotated in the axial direction of the clamp and the arc end is formed at the end. And the driven tooth tapping is performed on the hexagonal nut in the V-shaped cross section of the two sides, and the hex nut that completes the tapping is set in the groove of the V-shaped cross section on both sides by the tooth tapping rod. Gradually pushed by the hex nut that later completed the tapping until the end of the arc-shaped tooth tapping rod is collected.

It is only applicable to the hex nut or the tapping of the workpiece which can be embedded by the groove which is V-shaped on both sides, and the work such as the circumferential appearance is difficult to apply. Rotating the workpiece by a rotating clamp, and changing a tooth tapping in the axial center of the clamp and forming a tooth tapping rod at the tail end is only pushed forward to tap the workpiece to be tapped; The utility model mainly uses a resetting pressure cylinder to first push a pressing block to displace the tapping rod of the tooth tapping forward and abut against the workpiece to be tapped, so that the workpiece is flatly fitted to the top surface of the top material rotating shaft of the feeding mechanism. Above, then the pneumatic cylinder of the feeding mechanism is actuated, the pressure is greater than the pressure of the resetting cylinder, and the piston rod pushes the ejector rod to clamp the workpiece between the ejector shaft and the tapping rod The direction of the tapping spindle moves, and the workpiece and the tapping rod are pushed back by the ejector rod to prepare for the tapping position. When the workpiece is pushed to the position of the air collet, the pressing chamber is actuated. The rotating clamp clamps the workpiece, because the top shaft is freely rotatable The moving state, so the workpiece has no friction state, and then the resetting cylinder pushes the pressing block to push the tapping rod, so that the tapping of the tapping rod attacks the workpiece, and the rotation is completed after the tapping operation is completed. The clamp is released, and the reset cylinder will be displaced first, so that the workpiece completed by the tapping is pushed one by one to the end of the tapping rod, and is dropped by the bent end of the tapping rod and collected.

The prior art uses the method of resetting the cylinder to actuate the pressing block to drive the tooth tapping and the tooth tapping rod, which cannot take into account the fact that the workpiece is in the process of tapping, and the tooth tapping is initiated at the beginning of the workpiece, and it is necessary to provide a Larger force to overcome the resistance of the tapping, until the tooth tapping into the workpiece and forming a basic tooth shape in the workpiece, the resistance of the tapping will be lower than the initial one; due to the prior art, the resetting cylinder is used. It is impossible to provide different force of the tooth attack and the tooth tapping rod, so the smoothness of the tapping operation is affected, and the quality of the tapping is hard to be improved.

When the seat 322 is engaged, the seat 322 is moved back to the positioning position shown in the figure, so that the first elastic member 34 and the second elastic member 35 are compressed to accumulate the recovery energy.

Referring to the eighth figure, after the workpiece 12 to be tapped into the clamp 26 is clamped by the clamp 26, the push rod 145 will be operated back, and the new workpiece to be tapped 121 will fall to the load holder 13 again. in.

Referring to the ninth figure, the tooth tapping lever 27 is tapped by the tooth tapping 271. At this time, the action of the tooth tapping lever 27 in the grip groove 323 is gradually released, because the first elastic member 34 has The thicker wire diameter, so that the accumulated restoring force is larger and preferentially released, so that the first elastic member 34 pushes against the seat frame 321 and the front abutment 322 interlocks with the tooth tapping rod 27 in the grip groove 323. In the initial infeed, the first elastic element 34 can release a relatively large force to perform tapping; however, the displacement stroke and the tapping stroke of the first elastic element 34 will be the first guide. The long slot 3313 of the pivot portion 3311 of the lever 331 is restricted. In the pin body 3328, the pivot portion 3311 of the first guide rod 331 is moved out of the second guide rod 332 by the mount 321 to abut the long slot. At the rear end edge of the hole 3313, the displacement of the first elastic member 34 will be temporarily stopped.

Referring to the tenth figure, as described above, when the displacement of the first elastic member 34 is stopped, the second elastic member 35 having a smaller diameter behind the first elastic member 34 is released to release the restoring force, so that the second elastic member is replaced. 35, in the case that the rear end is locked by the inner hole 362 of the adjusting member 36, the head 3322 of the second guiding rod 332 is pushed forward by the front end thereof, and the seat frame 321 can be pushed forward to the movable seat 322. The tapping lever 27 is configured to enable the tooth tapping 271 to release a relatively small and appropriate biasing force to release a relatively smooth tapping after the tapping of the threaded portion 271, at which time the second elastic member 35 is The displacement stroke and the tapping stroke are limited by the position at which the positioning member 3326 is disposed on the positioning rod 3325 behind the rod portion 3324 of the second guide rod 332. When the positioning member 3326 is pressed against the adjusting member 36, the displacement of the second elastic member 35 Will terminate, at this time the tooth tapping 271 will be set to complete the tapping and reach the next workpiece to be tapped 121 falling in the loading base 13, while the workpiece 122 that has completed the tapping will be pushed and self-toothed The end portion of the tappet 27 is bent and collected.

In summary, the tapping device of the present embodiment not only adopts the push mechanism 3 which can be used for the two-stage tooth attack 271 and the tooth tapping rod 27, but also the first elastic member 34 and the second elastic force of the pushback mechanism 3. The displacement stroke and the tapping stroke of the member 35 are respectively limited by the positions of the long slot 313 of the pivot portion 3311 of the first guide rod 331 and the positioning member 326, and the adjusting member 36 is screwed at the position of the adjusting hole 318. It also determines that the entire push-back mechanism can fine-tune the tooth tapping 271 and the tapping stroke of the teeth. Therefore, the entire tapping device can effectively provide the different feeding force required for the initial tapping and further tapping stroke, so that the tapping process can be performed. Smoother, better tapping quality.

However, the above is only a preferred and feasible embodiment of the present invention. When it is not possible to limit the scope of the present invention, that is, the equivalent structural changes and modifications made by the applicant in accordance with the scope of the patent application and the contents of the new manual, All should remain within the scope of this new patent.
