Guide mechanism of screw boring machine

The invention relates to a guiding mechanism of a screw boring machine, in particular to a guiding mechanism of a screw boring machine which can strengthen the positioning of the pressure plate to maintain the smooth conveying of the screw material.

In general, the screw is mainly manufactured by using a boring machine to cut a screw material into a predetermined length to form a screw. The boring machine generally has a feeding device, a guiding mechanism and a dent device, that is, a screw material. The feeding device is placed into the feeding device and then introduced into the tooth device through the guiding mechanism to perform the tooth decay, and the movement of the screw material on the guiding mechanism is caused by the vibration of the machine table, but the guiding mechanism is susceptible to the vibration and causes the screw material. The stacking process causes the tooth decay process to be unsmooth. For example, in the mechanism disclosed in the new patent publication No. 509213, the structure such as the guide bar, the fixing piece and the cover strip is the above-mentioned guide mechanism, and the guide bar is used for guiding the screw material and the cover strip. That is, it is blocked above the screw material to avoid the guide of the screw material from the guide bar due to vibration. However, the cover strip is connected to the guide bar by the two fixing pieces, and the screw is only firmly positioned by the screw between the cover piece and the fixed piece. When the machine is vibrated, the cover strip is easily displaced relative to the fixed piece, resulting in an error in the parallelism between the cover strip and the guide bar, causing the screw material to be stacked, causing the tooth decay machine to malfunction. , And when the screw is not the same material specifications, must cover strip relative to the guide bar height adjustment, adjustment of the fixed structure between the cover sheet and strip hardly maintain the parallelism between the cover strip and the guide bar, in It is inconvenient to adjust.

Accordingly, it is an object of the present invention to provide a guide mechanism for a screw boring machine that allows the screw material to move more smoothly.

Therefore, the guiding mechanism of the screw boring machine of the present invention is disposed between one of the feeding device of the screw boring machine and a dent detecting device for guiding the screw material outputted by the feeding device to the dent device, the guiding The mechanism has two guiding plates, two positioning members and a pressing plate. The two guiding plates are arranged in parallel with each other, and one of the guiding plates is correspondingly formed with two limiting slots, and the two positioning members are respectively disposed corresponding to the two limiting positions. The groove protrudes upwardly from above the guide plate, and the pressure plate is connected to the positioning member and located above the guide plate, and the pressure plate and the two guide plates jointly define a conveying passage for guiding the screw material; The positioning members are limited to the limiting slots to position the pressing plate so that the screw material can smoothly move in the conveying passage.

Referring to the first, second and third figures, a preferred embodiment of the present invention The guiding mechanism 1 of the screw boring machine is disposed between one of the feeding device (not shown) of the screw boring machine and a dent device (not shown) for outputting the majority of the screw material of the feeding device 2 The guiding device and the toothing device are not characterized by the present invention, and therefore, the screw material 2 is a metal material that has not been tooth decayed, and has a screw head 21 and a screw body 22; The guiding mechanism 1 has two guiding plates 3, two positioning members 4 and a pressing plate 5, and the two guiding plates 3 are arranged in parallel with each other, and one of the guiding plates 3 is correspondingly formed with two limiting slots 31, each limit The slot 31 has two straight and spaced slot walls 311 and a slot bottom wall 312 connecting the slot walls 311. The slot walls 311 and the slot bottom wall 312 together define an upper and lower open channel 313. The positioning members 4 are respectively disposed in the channels 313 of the two limiting slots 31 and protrude upwardly above the guiding plate 3, and both sides thereof abut against the slot wall 311, and each positioning member 4 is formed with an opening facing downward. The elongated through groove 41 can be locked on the guide plate 3 through the elongated through groove 41 by a locking member 6 and can be moved up and down with respect to the channel 313 The positioning plate 4 is connected to the positioning member 4 and located above the guiding plate 3, and the positioning member 4 is formed to form two lateral adjusting slots 51, and is locked by a nut 71. The retaining member 7 can be locked by the corresponding positioning member 4 and the adjusting slot 51, and the pressing plate 5 and the positioning member 4 can be locked. At this time, the pressing plate 5 and the two guiding plates 3 are formed with a space and a common A conveying passage 8 for guiding the screw material 2 is defined.

In the process of guiding the screw material 2, the screw material 2 is in The conveying passage 8 is gradually moved, and the screw body 22 extends between the two guide plates 3, and the screw head 21 is located between the two guide plates 3 and the pressure plate 5, and the limit of the pressure plate 5 and the two guide plates 3 is limited. , the screw material 2 can be sequentially moved in the conveying channel 8; in addition, different specifications The size of the conveying passage 8 of the screw material 2 also needs to be adjusted accordingly. Firstly, the distance between the pressing plate 5 and the two guiding plates 3 is adjusted. First, the locking members 6 are loosened, and the positioning members 4 are simultaneously transferred. At this time, the positioning members 4 are limited by the corresponding limiting slots 31, so that they can only move up or down at the same time, that is, the two ends of the pressing plate 5 move synchronously, so as to ensure the levelness of the pressing plate after moving.
