Handheld punching device for steel structure

Abstract

The invention discloses a handheld punching device for a steel structure. The handheld punching device comprises a bottom plate and further comprises a locking mechanism and a drilling mechanism, wherein the locking mechanism is specifically composed of a sliding bin, a sliding block, a connecting rod and a strong magnet; the sliding bin is fixedly connected to the surface of the bottom plate; the sliding block is in sliding connection with the surface of the sliding bin in a matched manner; the connecting rod is welded to the surface of the sliding block; a strong magnet is mounted at one side of the surface of the connecting rod; the drilling mechanism is specifically composed of a drilling bin, a motor, a rotating rod, fan blades, a contact gear, a large gear, a gear beating fixing block and a limiting groove; the drilling bin is fixedly connected to the surface of the sliding block; the motor is mounted on the inner wall of the drilling bin; the rotating rod is welded to the power output end of the motor; and fan blades are welded to one side of the surface of the rotating rod. The whole device can be operated by a single hand and a single person under the auxiliary action of the sliding mechanism, drilling is conducted step by step through a differential method, accurate drilling is achieved, and the applicability of the whole device is higher.

Description

technical field [0001] The invention relates to the technical field of punching devices, in particular to a hand-held punching device for steel structures. Background technique [0002] In the follow-up maintenance and fixing of the steel structure, the method of drilling and covering the fixed steel bars will be used for maintenance, especially for the maintenance of high-altitude steel structures. The degree of danger will be greatly increased, and the punching machine will be held by people for a long time and the punching accuracy will be greatly reduced. [0003] Patent CN107838474A discloses a hand-held punching machine capable of rapid cooling, which relates to the technical field of hardware processing tools, and discloses a hand-held punching machine capable of rapid cooling, including a handle, and the bottom of the inner wall of the handle is connected to the The bottom of the battery is fixedly connected, the left side of the handle is fixedly connected with a c...
