[0002] Flange nuts are also called washer nuts, toothed nuts, hexagonal flange nuts, flange nuts, etc. They are mostly used in pipe connections or workpieces that need to increase the contact surface of the nut. One end of the nut has a wide flange that can be used as an integrated washer. This is used to distribute the pressure of the nut on the fixed part, thereby reducing the possibility of damage to the part and making it less likely to loosen due to uneven fastening surfaces. Most nuts are hexagonal, made of hardened steel, and usually zinc-plated. Flange nuts generally require a tapping device during processing.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1~Figure 2 As shown, this embodiment proposes a two-way feeding flange nut continuous tapping device, including a collecting box 1, a frame 2 is fixed on the top of the collecting box 1, two electric slide rails 3 are symmetrically fixed to the bottom wall of the crossbeam of the frame 2, matching electric sliders 4 are slidably installed on the bottom of the electric slide rails 3, connecting rods 5 are fixed to the bottom ends of the electric sliders 4, and No. 1 motors 6 are fixed to the bottom ends of the connecting rods 5. A tapping drill bit 7 is fixed on the power shaft of the No. 1 motor 6, feeding mechanisms 9 are fixed on both sides of the frame 2 through mounting frames 8, and driving gears 10 are fixed on the sides close to the feeding mechanisms 9, a supporting frame 11 is fixed to the middle of the top of the collecting box 1, and a driving mechanism 12 for driving the feeding mechanism 9 to rotate is fixed to the top wall of the supporting frame 11.

[0024] In this embodiment, the collection box 1 is used to collect metal scraps generated during the tapping process, the electric slide rail 3 is used to drive the No. 1 motor 6 at the bottom of the electric slide 4 to move, and the No. 1 motor 6 is used to drive the tapping drill bit 7 to work and perform tapping operations on the flange nuts. The feeding mechanism 9 is used to transmit unprocessed flange nuts and cooperate with the tapping drill bit 7 to perform tapping operations. There is no need to set up additional clamps to fix the flange nuts. The operation is simple and quick. The driving mechanism 12 is used to cooperate with the driving gear 10 to drive the feeding mechanism 9 to perform feeding operations.

[0025] Example 2

[0026] like Figure 2~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0027] The feeding mechanism 9 includes a mounting ring 91 fixed on the mounting frame 8, a turntable 92 is rotatably mounted in the mounting ring 91, a plurality of mounting grooves 93 are symmetrically provided on the outer edge of the turntable 92 away from the driving mechanism 12, and an annular baffle 94 is fixed on the side of the mounting ring 91 away from the driving mechanism 12. A feeding port 95 is provided on one side of the annular baffle 94, a discharge port 96 is provided on the bottom wall of the mounting ring 91, a discharge pipe 97 is fixed on the bottom wall of the mounting ring 91 corresponding to the discharge port 96, a tapping hole 98 is provided through the side wall of the turntable 92 corresponding to the mounting groove 93, and the driving gear 10 is fixed on the axial center position of the side wall of the turntable 92.

[0028] In this embodiment, a feeding mechanism 9 is provided for transmitting unprocessed flange nuts and cooperating with a tapping drill bit 7 to perform tapping operations. When the feeding mechanism 9 is working, the unprocessed flange nut is installed in the mounting groove 93 through the feed port 95. The driving mechanism 12 drives the turntable 92 to rotate through the driving gear 10. Under the action of the annular baffle 94, the flange nut stays stably in the mounting groove 93 until it moves to the top. At this time, the electric slide rail 3 is controlled to drive the electric slider 4 to move, thereby driving the No. 1 motor 6 to move. At the same time, the No. 1 motor 6 drives the tapping drill bit 7 to work. The tapping drill bit 7 passes through the tapping hole 98 and contacts the flange nut, thereby performing a tapping operation on the flange nut. After the tapping is completed, the flange nut can be discharged and collected through the discharge port 96 and the discharge pipe 97 when the turntable 92 moves to the bottom. In this embodiment, the end of the discharge pipe 97 can be set on the outside of the collection box 1 to facilitate material collection.

[0029] The driving mechanism 12 includes a No. 2 motor 121 fixed on the top wall of the support frame 11, a No. 1 bevel gear 122 is fixed on the power shaft at the top of the No. 2 motor 121, the No. 1 bevel gear 122 is meshedly connected with the No. 2 bevel gear 123, a driving shaft 124 is fixed at the axial position of the No. 2 bevel gear 123, and transmission gears 125 are fixed at both ends of the driving shaft 124, and the transmission gears 125 are meshedly connected with the corresponding driving gear 10. A protective shell is fixed on the top wall of the support frame 11 at a position corresponding to the driving mechanism 12, and the driving shaft 124 passes through the side wall of the protective shell through a bearing. The No. 2 motor 121 and the No. 1 motor 6 are servo motors or stepper motors.

[0030] In this embodiment, the driving mechanism 12 is used to cooperate with the driving gear 10 to drive the feeding mechanism 9 to perform the feeding operation. When the driving mechanism 12 is working, the second motor 121 drives the first bevel gear 122 to rotate, and the first bevel gear 122 drives the driving shaft 124 to rotate through the second bevel gear 123, thereby driving the transmission gears 125 on both sides to rotate, and the transmission gear 125 drives the turntable 92 to rotate through the driving gear 10. The protective shell is used to support and limit the driving shaft 124, and at the same time, it can prevent the operator from accidentally touching the contact position of the first bevel gear 122 and the second bevel gear 123 and causing injury.

[0031] Working principle: When the utility model is used, the unprocessed flange nut is first installed into the installation groove 93 through the feed port 95, and the No. 2 motor 121 is controlled to work intermittently, so that after each work of the No. 2 motor 121, the next installation groove 93 can just move to the position of the feed port 95, which is convenient for the next installation of the flange nut. Whenever the No. 2 motor 121 stops working, the electric slide rail 3 is controlled to drive the electric slider 4 to move, thereby driving the No. 1 motor 6 to move. At the same time, the No. 1 motor 6 drives the tapping drill bit 7 to work, and the tapping drill bit 7 passes through the tapping hole 98 and contacts the flange nut, thereby tapping the flange nut. After the tapping is completed, the electric slide rail 3 drives the electric slider 4 to drive the No. 1 motor 6 to move in the opposite direction, and at the same time, the No. 1 motor 6 rotates in the opposite direction, so that the tapping drill bit 7 can smoothly detach from the current flange nut until the No. 1 motor 6 moves to the initial position. As the turntable 92 continues to rotate, when the processed flange nut moves to the bottom, it can be discharged and collected through the discharge port 96 and the discharge pipe 97.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
