The present gang drill assembly comprises a first drive 1, a drill bit 22 and an adjustment member.

The drill 22 portion comprises a drill 22 base 21 and 24 drills 22, the 24 drills 22 are installed on the drill 22 base 21, the 24 drills 22 protrude out of the surface of the drill 22 base 21, the drill 22 base 21 and the first driving piece 1 are arranged at intervals, and the center of the drill 22 base 21 and the center of the first driving piece 1 are located on the same straight line.

The adjusting part comprises a universal mechanism 31 and a drill 22 adjusting part, the drill 22 adjusting part comprises swing arms 321, the number of the swing arms 321 is the same as that of the drill 22, namely, 24 swing arms 321 are arranged uniformly in the radial direction of a base 21 of the drill 22, and each drill 22 in the 24 drills 22 is mounted on the base 21 of the drill 22 through the corresponding swing arm 321.

In a preferred embodiment, the driving source 124 is preferably a motor, the number of the motors is 4, the 4 motors drive 24 drills 22 to drill, and 1 motor correspondingly drives 6 drills 22 according to the principle of uniform distribution and stable transmission.

In specific implementation, due to the position arrangement relationship of the 6 driven gears 122, only 2 driven gears 122 of the 6 driven gears 122 may directly engage with the driving gear 121, and the remaining 4 driven gears 122 may not directly engage with the driving gear 121. The power mechanism thus further includes an auxiliary transmission portion including an auxiliary gear 126, and the other driven gears 122 except the driven gear 122 directly engaging the driving gear 121 engage the driving gear 121 through the auxiliary gear 126.

Each drill bit 22 comprises a drill jig shaft 221, a thrust bearing 222, a needle bearing 223 and a drill bit 22 body, wherein the drill jig shaft 221 is rotatably arranged on the swing arm 321 through the thrust bearing 222 and the needle bearing 223, the drill jig shaft 221 is connected with the drill bit 22 body, and the drill bit 22 body is driven to rotate through the drill jig shaft 221 so as to realize the drilling operation of the drill bit 22 body. In order to reduce the phenomenon that the drill jig shaft 221 is locked, an oil cup 225 is arranged on the drill jig shaft 221, and the running stability of the drill bit 22 is improved through lubricating oil.

The body of the drill bit 22 may be directly connected to the drill shaft 221. Of course, the drill bit 22 may further include a reducing sleeve, the body of the drill bit 22 is connected to the drill mold shaft 221 through the reducing sleeve, and the bodies of the drill bits 22 with different sizes are installed by selecting the reducing sleeves with different sizes, so as to meet the drilling requirements of different bore diameters. For example, the diameter of the drill hole can be adjusted between 6cm and 20 cm.

The universal mechanism 31 comprises a universal coupling, one end of the universal coupling is connected with the gear transmission shaft 123, and the other end of the universal coupling is connected with the drill jig shaft 221. Namely, the gear transmission shaft 123 of the first driving member 1 is connected with the drill shaft 221 through a universal joint, and the drill shaft 221 is connected with the drill 22 body.

Preferably, the first adjusting hole 322 and the second adjusting hole 323 are both slotted holes, and the slotted hole of the base 21 and the slotted hole of the swing arm 321 of the drill 22 are locked by a fastener 324. For example, the fastener 324 may be a bolt and a nut, and the bolt passes through the first and second adjustment holes 322 and 323 in turn and is fastened by the nut.

In summary, the single swing arm 321 and the single universal mechanism 31 constitute a structure for adjusting the position of the single drill 22, and the swing arm 321 drives the universal mechanism 31 to adjust the position of the drill 22, so that the drilling operation of parts with different sizes can be adapted. In practical implementation, when the size of a component (here, a flange) is large, the nut is unscrewed at this time, the swing arm 321 is moved along the radial direction of the base 21 of the drill 22 and in a direction away from the center of the base 21 of the drill 22, at this time, the drill 22 is also moved along with the swing arm 321 in a direction away from the center of the base 21 of the drill 22, after the swing arm 321 is moved to the position, the bolt is tightened to lock the swing arm 321, that is, the position of the drill 22 is fixed, then the positions of 24 drills 22 are sequentially adjusted, at this time, the 24 universal couplings are in an expanded state, and a state that the position is adjusted to the maximum range is schematically shown in fig. 2. Similarly, when the size of the component (here, the flange) is smaller, at this time, the nut is unscrewed, the swing arm 321 is moved along the radial direction of the base 21 of the drill 22 and toward the direction close to the center of the base 21 of the drill 22, at this time, the drill 22 is also moved toward the direction close to the center of the base 21 of the drill 22 along with the swing arm 321, after the swing arm 321 is moved to the position, the bolt is tightened to lock the swing arm 321, that is, the position of the drill 22 is fixed, and then the positions of the 24 drills 22 are adjusted in sequence, at this time, the 24 universal couplings are in a closed state, wherein the state of adjusting to the minimum range is schematically shown in fig. 3.

In addition, the prior art needs about 20-30 seconds for drilling one hole, and about 720 seconds for drilling 24 holes, while the invention needs only about 60 seconds for drilling 24 holes, and can drill all the holes on the flange at one time, thereby greatly improving the working efficiency.

When 24 holes are not needed to be drilled, only the drill bit 22 body at the position where the holes are not needed to be drilled is detached, and the number of the drilled holes can be randomly adjusted from 1 to 24.

The group drilling machine comprises the group drilling assembly. Since the gang drill includes the above-described blade, all the advantageous effects of the above-described gang drill assembly are exhibited, and thus, they will not be described herein.
