The gearbox 103 has a lower drive column 203 movably mounted on the upper end of the mounting hole 202, a lower connecting seat 204 fixedly mounted on the bottom of the lower drive column 203, a secondary gear 205 movably mounted on the outer end of the lower drive column 203, a main gear 206 meshing with the center of the secondary gear 205, a rotating shaft 207 fixedly mounted on one side of the bottom of the gearbox 103, and a positioning shaft 208 fixedly mounted on one side of the top of the bottom mounting plate 201. A rotating hole 209 is also provided through one side of the bottom mounting plate 201. The rotating hole 209 is located at the outer end of the rotating shaft 207. A lower adjusting nut 210 is movably installed on the lower part of the rotating shaft 207. A positioning hole 211 is also provided through one side of the gearbox 103, and the positioning hole 211 matches the positioning shaft 208. An upper fixing nut 212 is movably installed on the upper end of the positioning shaft 208. Both the rotating shaft 207 and the positioning shaft 208 are threaded rods. A secondary drive hole 213 and a main drive hole are respectively provided in the secondary gear 205 and the main gear 206. 214. A main drive shaft 215 is movably installed in the center of the gearbox 103, and the top of the main drive shaft 215 is fixedly connected to the motor 104. The auxiliary drive hole 213 is matched with the lower drive column 203, and the main drive shaft 215 is matched with the main drive hole 214. Drill bits 217 are movably installed at the bottom of the lower connecting seat 204. Pins 216 are installed between the lower connecting seat 204 and the drill bit 217. The lower connecting seat 204 has a T-shaped column structure.

[0028] Specifically, the modular multi-head drill is a high-efficiency drilling device, typically used for large-scale, multi-hole machining tasks. When the auxiliary gear 205 or main gear 206 in the gearbox 103 of the multi-head drill body 100 is worn or damaged, the lower adjusting nut 210 at the bottom of the rotating shaft 207 and the upper fixing nut 212 at the upper end of the positioning shaft 208 can be directly unscrewed to move the bottom mounting plate 201 down and rotate it out. The damaged auxiliary gear 205 or main gear 206 can then be directly removed from the upper end of the rotated bottom mounting plate 201 and replaced in the same position. This completes the replacement of the auxiliary gear 205 or main gear 206 in the gearbox 103, avoiding the need to disassemble the entire gearbox 103, remove internal connecting parts, and disassemble the bottom drill bit 217.

The positioning shaft 208 fixedly installed on one side of the bottom mounting plate 201 can be used for positioning between the auxiliary gear 205 or the main gear 206 in the bottom mounting plate 201 and the gearbox 103 after replacement, and can also be used for locking and fixing with the gearbox 103. The main drive hole 214 opened in the main gear 206 can also be independently engaged with the main drive shaft 215, so as to facilitate the separate disassembly of the main gear 206 after damage.

[0029] Working principle and usage process of this utility model:

[0030] After the main gear 206 in the gearbox 103 of the multi-head drill body 100 is worn and damaged, first loosen the lower adjusting nut 210 at the bottom of the rotating shaft 207 to lower it to the bottom end of the rotating shaft 207. Then remove the upper fixing nut 212 at the upper end of the positioning shaft 208. After removing the upper fixing nut 212, move the bottom mounting plate 201 at the bottom of the gearbox 103 down. After the bottom mounting plate 201 moves along the rotating shaft 207 to the upper end of the lower adjusting nut 210, rotate the bottom mounting plate 201 180 degrees clockwise along the rotating shaft 207. After the bottom mounting plate 201 rotates, the damaged main gear 206 will be remembered. After removing the damaged main gear 206 and installing the new main gear 206 in its original position, the base mounting plate 201 can be rotated 180 degrees in the opposite direction around the rotating shaft 207 to reset it. After resetting the base mounting plate 201, it can be moved upward so that the positioning shaft 208 on one side of the base mounting plate 201 moves into the positioning hole 211 in the gearbox 103. After the base mounting plate 201 is moved upward to fit the bottom of the gearbox 103, the fixing nut 212 can be reinstalled and the lower adjusting nut 210 at the bottom of the rotating shaft 207 can be tightened, thus quickly completing the replacement of the damaged main gear 206 in the gearbox 103.
