It is the main machining mechanical facility for various workpiece processing. As a commonly used mechanical workpiece in industrial production, pipe fittings usually use lathe equipment to perform operations such as opening holes. Since pipe fittings are generally long, an auxiliary positioning mechanism is needed to support and position them to ensure the accuracy of drilling. As shown in a machining auxiliary mechanism for plug drilling of a steel bar tensioning machine disclosed on the Chinese Patent Network (publication number CN219052989U), when such a device performs auxiliary positioning on pipe fittings, through the cooperation of a mounting frame, a vertical rod, a connecting cylinder, a slider, a first limit bolt, a vertical plate, a threaded fixing rod, a screwing rod, and a fixing pressure plate, it can not only quickly, accurately, and stably position and fix the plug to be drilled, but also quickly release the fixation of the plug after the drilling is completed and quickly remove the plug, thereby improving the efficiency of drilling the plug.

[0003] However, for the above-mentioned disclosed patents and the pipe fitting auxiliary positioning mechanisms adopted in the existing market, there are still some deficiencies: the existing form of using manual control to perform auxiliary positioning on pipe fittings and then drilling has a high labor intensity of manual fixation and low efficiency, and the drilling production efficiency of pipe fittings is not high.

[0021] One side of the support of the braking seat 3 is rotatably connected with a propulsion wire sleeve 15, and a propulsion screw rod 4 connected to the clamping seat 5 is screwed through the inside of the propulsion wire sleeve 15. The other side of the support of the braking seat 3 is rotatably connected with a transmission shaft 13 perpendicular to the direction of the propulsion wire sleeve 15. A transmission worm 14 is arranged in the middle of the shaft rod of the transmission shaft 13. A transmission worm wheel 16 meshing with the transmission worm 14 is sleeved outside the sleeve of the propulsion wire sleeve 15. When the transmission shaft 13 rotates, it drives the transmission worm 14 to rotate. By using the meshing transmission of the transmission worm 14 and the transmission worm wheel 16, it drives the propulsion wire sleeve 15 to rotate, converts the rotational force into a horizontal thrust, and pushes the propulsion screw rod 4 to expand and contract and brake along the braking seat 3, and pushes the two groups of clamping seats 5 opposite horizontally to clamp and push, and uses the clamping seat 5 to mechanically clamp and position the pipe fittings to be drilled.

[0022] A clamping seat 5 is installed at the top end of the propulsion rod of the propulsion alignment assembly. Three pairs of pressure knobs 21 are screwed through the clamping seat 5 in a star-delta form along its circumferential direction. By using the knob pair clamping of the star-delta arranged pair of pressure knobs 21, the size of the pair clamping space is adjusted to adapt to the pair clamping and fixing work of pipe fittings of different sizes.

[0023] The upper end of the bracket of the tooling rack 1 is provided with a bottom support alignment assembly, and the top end of the lifting rod of the bottom support alignment assembly is installed with a bottom support seat 9 horizontally opposite to the clamping seat 5.

Subsequently, place the pipe fittings inside the clamping seat 5, and only need to turn one or two groups of pressure - opposing knobs 21 to tightly press and position the pipe fittings at the center;

[0026] Then, horizontally align the pipe fittings with the clamping seat 5, synchronously control the braking motor 20 to work, drive the combined transmission of the differential pulley B19, differential belt 18, and differential pulley A17, and then drive the transmission shaft 13 to rotate. As a power source, drive the combined transmission of the transmission worm 14 and transmission worm wheel 16, and then drive the advancing screw sleeve 15 to rotate, convert the rotational force into a horizontal thrust, push the advancing screw rod 4 to expand and contract and brake along the braking seat 3, push the two horizontally - opposite clamping seats 5 to clamp each other, and use the clamping seat 5 to mechanically clamp and position the pipe fittings to be drilled;

[0027] When subsequently drilling the pipe fittings, control the driving motor 11 to work, drive the driving gear 12 to rotate, use the meshing transmission of the driving gear 12 and the driving rack 6, convert the meshing force into a horizontal thrust, push the guiding slide 10 to slide along the track of the guiding slide rail 7, and then push the bottom support seat 9 to horizontally slide along the direction of the pipe fittings to be drilled. Horizontally displace the bottom support seat 9 to one side of the position to be drilled. Synchronously control the expansion and contraction and braking of the electric push rod 8, push the bottom support seat 9 to vertically displace, and make the bottom of the bottom support seat 9 fit and support under the pipe fittings, horizontally support the pipe fittings, reduce the load force during pipe fitting drilling, and avoid situations such as bending, deformation, and inaccurate drilling of the pipe fittings.
