Tapping method of gold-ingot-way explosion-proofing threading box and equipment thereof

Abstract

The invention relates to a tapping method of a gold-ingot-way explosion-proofing threading box and equipment thereof. The tapping method is operated according to the following steps that a first tapping mechanism and a second tapping mechanism are jointly operated to a place adjacent to the junction, and the place adjacent to the junction serves as a starting position of tapping time division multiplexing; the first tapping mechanism carries out tapping and exits to the corresponding starting position; the second tapping mechanism carries out tapping and exits to the corresponding starting position; the first tapping mechanism and the second tapping mechanism jointly exit a workpiece; and initially, the first tapping mechanism and the second tapping mechanism respectively enter a first screw hole and a second screw hole till the first tapping mechanism and the second tapping mechanism reach the respective places adjacent to the junction, at the moment, a sufficient distance exists between the two tapping mechanisms to enable one tapping mechanism to tap firstly, after tapping is completed, and the tapping mechanism exits to the place outside the place adjacent to the junction and waits for the other tapping mechanism to exit jointly after tapping by the other tapping mechanism is completed. In the way, the stability of the workpiece during machining is effectively guaranteed, and the two tapping mechanisms cannot be rubbed and even damaged.

Description

technical field [0001] The invention relates to a tapping method for Yuanbaotong explosion-proof threading box and a tapping device adapted to the tapping method. Background technique [0002] Such as Figure 4 As shown, the Yuanbaotong explosion-proof wiring box includes a square hole at one end, and a first screw hole A1 and a second screw hole A2 that extend symmetrically from the square hole to the other two ends and form a specific angle. If the tapping of the first screw hole A1 and the second screw hole A2 is carried out at the same time, when crossing the border point, the tapping bit of the first tapping mechanism and the tapping bit of the second tapping mechanism will be due to leaning against each other. If it is too tight, it will cause friction and even damage the tapping bit. Another tapping scheme for the tapping equipment of Yuanbaotong explosion-proof threading box is to tap the first screw hole first, exit, and then perform the tapping process on the seco...

AI Technical Summary

Problems solved by technology

The defect of this tapping scheme is that when the tapping bit of the first tapping mechanism enters the first screw hole, due to the asymmetrical azimuth of the action of the tapping bit, it is very easy to make one end of the second screw hole warp, Make the threaded hole center line deviate from the standard axis position, and tap unqualified workpieces
