[0019] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] An automatic tapping device applied to folded parts, as Figures 1 to 2 shown, includes a workbench 1, a feeding box 2, a conveying track 3, a tapping machine 5, and a controller. The conveying track 3 is arranged on the workbench 1 and is connected to the feeding box 2 on one side of the workbench 1. The discharging end of the conveying track 3 is connected to a support seat 16. Above the support seat 16, a tapping machine 5 is arranged. The controlled end of the tapping machine 5 is connected to the output end of the controller.

[0021] The upper part of the conveying track 3 is provided with a workpiece guiding groove arranged in an L shape, which can stably convey the bent workpiece 4.

[0022] An inclined discharging groove 14 is installed on the left side of the support seat 16, and the bottom end of the discharging groove 14 is connected to a collecting box 15.

[0023] Clamping components for clamping the workpiece 4 are arranged on the left and right sides of the support seat 16, as Figure 1 shown. One side of the clamping component is connected to a double-axis cylinder 10. The double-axis cylinder 10 is installed on the workbench 1, and the controlled end of the double-axis cylinder 10 is connected to the output end of the controller.

[0024] The clamping component includes a bent pushing plate 11 arranged on one side of the support seat 16 and a bent clamping plate 13 arranged on the other side of the support seat 11, as Figure 2 shown. The horizontal part of the pushing plate 11 is slidably arranged on the top of the support seat 16 and abuts against the horizontal part of the workpiece. The horizontal part of the clamping plate 13 abuts against the vertical part of the workpiece. The pushing plate 11 and the clamping plate 13 are connected by a connecting shaft 12 passing through the support seat 16. The vertical part of the pushing plate 11 is connected to the double-axis cylinder 10.

[0025] The tapping machine 5 is arranged on a guide post 7 on one side of the workbench 1. Two taps 6 are installed at the bottom of the tapping machine 5 through a multi-spindle head, and a lifting mechanism for driving the taps 6 to lift is arranged inside the tapping machine 5. The controlled end of the lifting mechanism is connected to the output end of the controller.

[0026] The lifting mechanism can adopt a hydraulic lifting structure such as cylinder lifting or oil cylinder lifting, or an electric lifting structure such as an electric lifting rod or the cooperation of a lead screw and a nut for lifting.

[0027] A horizontal connecting rod 8 connected to the multi-spindle head is arranged below the tapping machine 5, as Figure 1 shown. A slider 9 slidably fitted with the guide post 7 is arranged at the end of the connecting rod 8, which can guide the lifting of the taps 6.
