[0002] Some decorative workpieces often require a large number of drills (drills refer to small-sized artificial zircons or other artificial gemstones) to enhance the overall beauty of the decoration. In order to reduce labor costs, the zircon jewelry industry often uses automatic wax setting machines. The drill needle device of the wax setting machine is used to clamp the drill on the wax setting to achieve wax setting. At present, the drill needle includes a frame, and the wax mold is placed on the frame. The cylinder drives the drill needle to move in the vertical direction, sucks the gemstones and diamonds and moves them to the wax mold, and drills the designated position of the wax mold to fix the artificial diamond on the wax mold, completing the drill work.

DETAILED DESCRIPTION

[0023] In this embodiment, if Figures 1 to 6 An automatic feeding device for a spot drilling machine is shown, which comprises a mounting platform 1, a storage bin 2, a translation sliding plate 3 and a driving device 6; a plurality of mounting grooves 11 are evenly arranged on the mounting platform 1, and a slidable translation sliding plate 3 is installed in the mounting groove 11; a feeding hole 12 is opened on one side of the mounting platform 1, and the storage bin 2 is installed on the top of the mounting platform 1 and is connected with the mounting groove 11 through the feeding hole 12; a driving device 6 is installed at one end of the mounting groove 11 away from the feeding hole 12, and the driving device 6 is used to push the translation sliding plate 3 to slide in the mounting groove 11, thereby pushing out the feeding fixture 7 in the mounting groove 11. When in use, the driving device 6 pushes the translational sliding plate 3 to slide in the mounting groove 11 of the mounting platform 1. A storage bin 2 is installed above the mounting groove 11. The storage bin 2 stores diamonds, zircons, etc. for spot drilling. When the translational sliding plate 3 moves, the loading jig 7 on the translational sliding plate 3 scrapes the gems in the storage bin 2, thereby loading the diamonds onto the loading jig 7. As the driving device 6 continues to push, the loading jig 7 is pushed out of the mounting platform 1, so that the needle of the spot drilling machine can grab the diamonds on the loading jig 7 for spot drilling. The automatic loading mechanism of the utility model has a simple structure, and loading can be completed by a reciprocating scraping action of the driving device 6, so that loading is more efficient. At the same time, when diamonds of different sizes need to be drilled, the loading fixture 7 can be pulled out from the translation sliding plate 3 to replace the new loading fixture 7, and the replacement is also faster; and the loading fixture 7 on the mounting platform 1 can be defined and configured according to the product, and can be used alone, in parallel or in series, etc., which greatly improves the convenience of taking materials. The automatic loading structure of the utility model makes the processing efficiency of the automated wax setting machine more efficient.

[0024] In this embodiment, if Figures 2 to 4 As shown, a sliding guide rail 8 is provided in the installation groove 11 , a slider 81 is slidably installed on the sliding guide rail 8 , the slider 81 is nested in the translation sliding plate 3 , and the driving device 6 drives the translation sliding plate 3 to reciprocate along the sliding guide rail 8 .

[0025] In this embodiment, the driving device 6 is a driving motor, the power output shaft of the driving motor is connected to the transmission screw 5, the translation sliding plate 3 is installed with a transmission block 4, and the transmission block 4 is in transmission connection with the transmission screw 5. When in use, the driving motor drives the transmission screw 5 to rotate, and the transmission block 4 is connected to the translation sliding plate 3. When the transmission screw 5 rotates, the transmission block 4 drives the translation sliding plate 3 to move along the axial direction of the transmission screw 5, thereby driving the translation sliding plate 3 to slide in the installation groove 11. The translation driven by the transmission screw 5 can make the moving position more accurate.

[0026] In this embodiment, the driving motor is a stepping motor.
