Problems solved by technology

One end of the expansion tube of the expansion screw is generally provided with four or six grooves. The existing slotting method is generally to clamp the expansion tube first, then use a cutting machine to slot, then loosen the expansion tube, and turn the expansion tube to a certain angle. Re-clamping and slotting on the cutting machine, but this slotting method is not only inefficient, but also the angle between the slots is not uniform, which affects the subsequent fastening effect

Abstract

The invention discloses an expansion tube grooving device for an expansion screw. The expansion tube grooving device comprises a sliding rail fixed on a rack, a chuck seat capable of axially moving is connected to the sliding rail in a sliding mode, a chuck for fastening an expansion tube is hinged to the chuck seat, an annular strip-shaped rack is arranged on the right side of the chuck, the annular strip-shaped rack is tensioned on two belt wheels arranged up and down, the belt wheels are hinged to the rack through belt wheel shafts, and a motor for driving one belt wheel shaft to rotate is arranged on the rack; and a handle is fixed on the chuck. The expansion tube can be quickly fastened and positioned through the chuck and a positioning block, the expansion tube can be quickly grooved by moving and rotating the chuck, and the grooving quality is stable.

Description

technical field [0001] The invention relates to the technical field of screw production, in particular to an expansion tube slotting device for expansion screws. Background technique [0002] Expansion screws generally refer to metal expansion screws. The expansion screw is fixed by using the wedge-shaped slope to promote the expansion to generate friction and grip force to achieve the fixing effect. One end of the expansion tube of the expansion screw is generally provided with four or six grooves. The existing slotting method is generally to clamp the expansion tube first, then use a cutting machine to slot, then loosen the expansion tube, and turn the expansion tube to a certain angle. Re-clamping and slotting on the cutting machine, but this slotting method is not only inefficient, but also the angle between the slots is not uniform, which affects the subsequent fastening effect. Contents of the invention [0003] The purpose of the present invention is to overcome th...
