Description

Technical Field

[0001] The utility model relates to the field of drilling, in particular to a rapid reversing and positioning automatic drilling device. Background Art

[0002] The switch cabinet shaft is an important component of the switch cabinet. The switch cabinet shaft not only connects the interlocking mechanism of the switch cabinet, but also is an important intermediate piece for connecting the hand crank. When connecting the hand crank, in order to prevent the hand crank from sliding, two 90-degree threaded holes need to be opened in the radial direction of the shaft. Then, screws are used to tighten the hand crank to prevent the hand crank from loosening. Traditionally, the threaded holes on the shaft are processed by manually moving the tap down to drill a threaded hole, then rotating it 90 degrees, and then drilling another threaded hole. This processing method is inefficient and has low processing accuracy.

[0003] Chinese utility model patent CN 203292627 U discloses a tap holder for drilling threaded holes in wind turbine flanges. The holder comprises a vertical cylindrical tap holder, a cylindrical blind hole whose central axis coincides with the central axis of the holder, and a threaded through hole whose central axis perpendicularly intersects the central axis of the blind hole. A tightening screw is disposed within the threaded through hole. A cylindrical lever, whose central axis perpendicularly intersects the central axis of the holder, is disposed on the upper end of the tap holder. The lever's two ends extend outwardly beyond the upper end of the tap holder. This utility model results in low threaded hole drilling efficiency, low precision, and high processing costs. Utility Model Content

The vertical rotating shaft is driven by a servo motor fixed on the support frame and driven by a servo motor A worm gear reduction motor, a gear meshing with a rack is fixed on the output shaft of the first worm gear reduction motor; the switch cabinet shaft mounting mechanism includes a first slide moving along the "Y" direction, a second slide moving along the "X" direction is installed above the first slide, the first slide is driven by a second motor installed on the support plate, and the second slide is driven by a third motor fixed on the second slide, a group of shaft mounting parts are fixed on the second slide, the shaft mounting parts include a vertical block fixed on the second slide, a rotating shaft is rotatably connected to the vertical block, a second worm gear reduction motor driving the rotating shaft is fixed on the vertical block, a first block is fixed on the outer end of the rotating shaft, a second block with a cross-section smaller than the first block is fixed on the outer end of the first block, a fan-shaped hole with an angle of 90° is opened on the rotating shaft, and a limit block matching the fan-shaped hole is fixed on the vertical block; a magnet is fixed on the outer end face of the rotating shaft, and a switch and a single-chip microcomputer controller are installed at the base. The drilling mechanism is used to drill threaded holes in the switchgear shaft. The switchgear shaft mounting mechanism is designed to accommodate multiple switchgear shafts. The microcontroller controller is a commercially available product, including products from Freescale, Renesas Electronics, Infineon, and Toshiba. The first worm gear reducer and the first worm gear reducer ensure precise displacement without offset. The rack and pinion drive the longitudinal rod, thereby moving the tap up and down, through gear rotation. The anti-rotation guide block and guide rod prevent the longitudinal rod from rotating along with the rod. The vertical retaining block and vertical retaining slot ensure that the rod rotates along with the vertical shaft, and that the rod can also rotate along with the vertical shaft when it moves up and down. The first worm gear reducer ensures precise control of the longitudinal rod's up and down movement.

The function of the first self-lubricating sleeve is to reduce friction resistance and make the longitudinal rod move more smoothly, thereby preventing jamming. The first self-lubricating sleeve is made of tin bronze.

[0007] Further improvement, the anti-rotation guide block is provided with a second self-lubricating sleeve, and the guide rod is plugged into the second self-lubricating sleeve. The function of the second self-lubricating sleeve is to reduce friction resistance when the anti-rotation guide block moves on the guide rod, making the movement smoother and preventing jamming. The second self-lubricating sleeve is made of tin bronze.

[0008] To further improve the base, support legs are fixed at the four corners of the base. The function of the support legs is to make the base more stable.

The rotation of the vertical shaft 5-1 will synchronously drive the insertion rod 5-3 to rotate. Then, the first worm gear reduction motor 5-6 drives the gear 5-7 to rotate. The rotation of gear 5-7 will drive the longitudinal rod 5-4 to move downward, thereby driving the tap 5-5 to move downward as well. The tap 5-5 moves downward to drill the first threaded hole 9-1, and then the tap 5-5 immediately moves upward to reset. Then, the second worm gear reduction motor 6-5c drives the switch cabinet shaft workpiece 9 to rotate 90° and limits the precise angle through the limit block 6a-5a. After the switch cabinet shaft workpiece 9 rotates 90°, the tap 5-5 immediately moves downward again and drills another threaded hole 9-1. Then, in the same way, the threaded holes 7-1 are drilled one by one for the remaining switch cabinet shaft workpieces 9. This method has extremely high efficiency, extremely high processing precision, high degree of automation, low labor cost, and low cost, and is worthy of promotion and application.
