Tapping device suitable for gap hole and work method thereof

Abstract

The invention discloses a tapping device suitable for a gap hole and a work method thereof. The tapping device comprises screw taps with holes, a supporting plate, a bottom plate and guide rods. The heads of the screw taps with the holes are provided with sleeving holes, the screw taps with the holes are mounted on chucks, the chucks are connected with rotating shafts, the rotating shafts are connected into a multi-shaft box, and are driven by a spindle to synchronously rotate and turn over, the supporting plate is provided with a positioning rod, pins are mounted on the top of the supportingplate, the pins are matched with the sleeving holes of the screw taps with the holes, the bottom plate is mounted on a worktable and is located below the supporting plate and is kept distance from thesupporting plate, spring sleeves are mounted on the four corners of the bottom of the bottom plate, the supporting plate can get close to the bottom plate during tapping, and the supporting plate canreturn to the initial position through reset springs after tapping is finished, the guide rods are mounted on the bottom plate, and position and lift a hole plate with a gap, the hole plate with thegap is suspended when the supporting plate descends, and motion of the supporting plate is guided. In the tapping process of the screw taps, dual-way positioning is achieved, self-center tapping is achieved, the device is suitable for machining of a bottle hole with a gap, machining precision is high, and adaptation is wide.

Description

technical field [0001] The invention belongs to the field of tension plate processing, and in particular relates to a tapping device suitable for notched holes and a working method thereof. Background technique [0002] In the process of producing tensioned plates, the company first stamps the counterbore, through hole, and strip groove, and then taps the through hole. Because the strip groove makes the through hole have a gap, the tap is prone to deflection and rotation. During the process, the force is uneven, the position is shifted, the quality of the processed thread is poor, or the tap is broken. Existing tapping devices all have this kind of situation when processing holes with notches, and there is no particularly good solution, and the taps can only be constantly replaced. Contents of the invention [0003] Aiming at the above-mentioned deficiencies existing in the prior art, the technical problem to be solved by the present invention is that when the existing ta...

Problems solved by technology

[0003] Aiming at the above-mentioned deficiencies existing in the prior art, the technical problem to be solved by the present invention is that when the existing tapping device is processing a hole with a notch, the force on the tap is not uniform, and it is easy to vibrate, resulting in irregular threads. , It is also easy to cause the tap to break and affect the work progress
