DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a part tapping mechanism includes a bracket 3, a cavity is set in the middle of the bracket 3, a spindle motor 10 and a motor fixing frame 11 are both located in the cavity, and a plurality of weight-reducing holes are set on both sides of the bracket 3. A motor protective cover 6 and a bracket protective cover 9 are fixed to the rear side of the bracket 3, the motor protective cover 6 is located on the upper side of the spindle motor 10, and the bracket protective cover 9 is located on the upper side of the motor protective cover 6, and the protective cover can prevent iron filings from flying into the transmission components inside the bracket 3.

[0020] The front side of the bracket 3 is slidably mounted with a sliding plate 4 through a slide rail, and a first sleeve 13 is fixedly passed through the sliding plate 4, and a first rotating shaft 12 is passed through the interior of the first sleeve 13, and the first rotating shaft 12 is rotatably connected to the first sleeve 13. A motor fixing frame 11 is fixedly mounted on the end surface of the first sleeve 13, and a spindle motor 10 is mounted on the motor fixing frame 11. The output end of the spindle motor 10 is connected to one end of the first rotating shaft 12 through a coupling, and the coupling is located in the inner cavity of the motor fixing frame 11.

[0021] A gear protection cover 8 is installed at the front side of the sliding plate 4. Two shaft holes 19 are arranged on the gear protection cover 8. The second shaft sleeves 18 are fixedly penetrated inside the two shaft holes 19. The second shaft sleeves 18 are penetrated inside the second shaft sleeves 18. The second shaft sleeves 18 are rotatably connected with the second shaft 17. A driven gear 14 is installed at the rear end of the second shaft 17. A tapping tool is installed at the front end of the second shaft 17. A main gear 16 is installed at the front end of the first shaft 12. A transmission gear 15 is meshed between the main gear 16 and the two driven gears 14. The main gear 16, the transmission gear 15, and the driven gear 14 are all located inside the gear protection cover 8. When the spindle motor 10 rotates, it drives the first shaft 12 to rotate through the coupling, thereby driving the main gear 16 to rotate. When the main gear 16 rotates, it drives the two transmission gears 15 to rotate, thereby driving the two driven gears 14 to rotate. When the two driven gears 14 rotate, they drive the two second shafts 17 to rotate, thereby driving the tapping tool to rotate.

[0022] The gear guard 8 is fixedly connected to the front side of the sliding plate 4 by bolts, and a cutter head guard 7 is fixed to the upper side of the gear guard 8.
