Embodiment Construction
[0008] The reference signs in the drawings of the description include: input gear 1, input shaft 2, transmission gear 3, motor 4, transmission shaft 5, transition gear 6, idler gear 7, support plate 8, directional ratchet 9, output shaft 10, which can be Adjustment handle 11, double-sided ratchet 12, output gear 13.
[0009] Below in conjunction with accompanying drawing and embodiment technical solution of the present invention is described in further detail:
[0010] Such as figure 1 As shown, a variable-speed two-way tapping machine according to an embodiment of the present invention includes an input shaft 2 , an output shaft 10 and a support plate 8 . One end of the input shaft 2 is key-connected with the input gear 1, and the other end is connected with the motor 4 and drives the input shaft 2 through the motor 4. The input gear 1 is a bevel gear fixedly connected with two large end faces. The support plate 8 is movably connected with a transmission shaft 5 and an outp...

The invention discloses a variable-speed bi-directional tapping machine which comprises an input shaft, an output shaft and a supporting plate. One end of the input shaft is connected with an input gear in a key connection mode, and the input gear is a bevel gear with two large end faces fixedly connected; a transmission shaft and the output shaft are movably connected to the supporting plate and located on the two sides of the input gear respectively; one end of the transmission shaft is connected with a transmission gear meshed with the input gear in an interference fit mode, and the other end of the transmission shaft is connected with a transition gear in an interference fit mode; one end of the output shaft is connected with an output gear through a bearing, the other end of the output shaft is connected with an idle gear through a bearing, and the output gear and the input gear are meshed; a double-faced ratchet wheel is arranged between the idle gear and the output gear, and the double-faced ratchet wheel is connected with the output shaft in a key connection mode and can slide in the axial direction of the output shaft; the end face of the idle gear and the end face of the output gear are fixedly connected with directional ratchet wheels capable of being connected with the double-faced ratchet wheel in a clamping mode. Tapping in and tapping out can be achieved without a double-faced motor, and rotation speed is increased in the tapping out process, so that machining time is greatly saved.
Description
technical field [0001] The invention relates to a threaded part, in particular to a variable-speed two-way tapping machine for processing threaded holes on an air-conditioning panel. Background technique [0002] In the prior art, threaded holes need to be processed on the air conditioner panel so that the air conditioner panel can be fixed on the main box body of the air conditioner through bolts. The general-purpose tapping machine has a large volume, and generally uses a double-sided motor to realize the tapping and exiting of the tapping. When the motor rotates forward, the tapping advances; when the motor reverses, the tapping exits. The method of using the forward and reverse rotation of the motor to realize the attacking and withdrawing of the tapping has low efficiency and poor reliability, and will greatly shorten the life of the motor; the speed of attacking and withdrawing during tapping is the same, which wastes processing time.
