Full-automatic tapping machine for metal manufacturing

Abstract

The invention relates to the technical field of threaded part machining, and discloses a full-automatic tapping machine for metal manufacturing, which comprises a worktable, a clamping mechanism is mounted on the upper surface of the worktable, a lifting mechanism is mounted on the left side of the upper surface of the worktable, and a main body is fixedly mounted on a moving rod of the lifting mechanism; a drill bit is movably mounted in the main body, and a threaded section of the drill bit extends out of the main body. Through the arrangement of the fixed ball and the contact ball, in the tapping process of the drill bit, when the resistance borne by the drill bit is large, the contact ball and the fixed ball can instantly slide relative to each other, so that the driving seat moves upwards, and then the magnetic attraction force between the electromagnet and the magnet overcomes the elastic force of the elastic piece; the rotating force generated by the motor is not transmitted to the drill bit through the contact ball any more, the drill bit stops rotating, and therefore the situation that when the tapping resistance is large, the drill bit continues tapping, the drill bit is broken in a workpiece, and the follow-up workpiece machining efficiency is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of screw processing, in particular to a fully automatic tapping machine for metal manufacturing. Background technique [0002] In the processing of metal parts, sometimes it is necessary to tap the internal thread of the metal parts, so that the metal parts can be fixed and installed with screws during the subsequent installation and use. Nowadays, fully automatic tapping machines are usually used to complete the above operations. . [0003] In the process of using the existing fully automatic tapping machine, first the metal piece to be tapped is placed in the clamping mechanism at the position below the drill bit through the feeding mechanism, and the clamping mechanism is made to clamp the metal piece, and then, the The power source drives the drill bit to rotate, and drives the drill bit to move downward through the lifting mechanism, so that the drill bit extends into the round hole on the metal part, ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing fully automatic tapping machine proposed in the background technology, the present invention provides a fully automatic tapping machine for metal manufacturing, which can prevent the drill bit from breaking inside the workpiece and affect the subsequent processing of the workpiece. The advantages of efficiency, solve the technical problems raised in the above background technology
