Metal plate drilling device

Abstract

The invention relates to the field of drilling equipment, and discloses a metal plate drilling device. The metal plate drilling device comprises a base. An end face bearing is fixedly arranged on oneside of the top of the base. A supporting column is fixedly sleeved with the middle portion of the end face bearing. The top end of the supporting column is fixedly sleeved with a rotation block. A sliding rod is fixedly connected to the side face of the rotation block. The end, away from the rotation block, of the sliding rod is fixedly connected with a limiting baffle. According to the metal plate drilling device, a positioning nut rotates on a threaded rod, and the deepest punching position is determined in cooperation with the positions of a right side marker post and a dividing ruler. During punching, only a moving pipe needs to be downwards moved, a drill bit is driven to move downwards to conduct drilling till a left side marker post makes contact with the positioning nut, then drilling is conducted to the deepest position, accordingly, the situation that the metal plate depth cannot be accurately controlled, the metal plate drilling quality cannot meet the project requirement,consequently, raw materials are wasted, and the metal plate machining efficiency is reduced is avoided.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a metal plate drilling device. Background technique [0002] Drilling device refers to the general term for equipment used to process holes on solid materials. Common drilling devices include electric drills, drilling machines, and drilling devices are widely used. In the construction industry, they are suitable for building beams, plates, columns, Wall reinforcement, decoration, wall installation, installation of brackets, railings, billboards, outdoor units of air conditioners, guide rails, satellite receiver elevators, steel structure workshops, etc. [0003] However, the common drilling device cannot accurately control the depth of the metal plate when drilling the metal plate, so that the quality of the metal plate drilling cannot meet the engineering requirements, resulting in waste of raw materials and reducing the processing efficiency of the metal plate. Moreover, when...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a metal plate drilling device, which has the advantages of being convenient to precisely control the drilling depth and fixing the thinner metal plate, and solves the problem of the common drilling device in the metal plate. When drilling, the depth of the metal plate cannot be accurately controlled, so that the quality of the metal plate drilling cannot meet the engineering requirements, resulting in waste of raw materials and reducing the processing efficiency of the metal plate, and common drilling devices are not suitable for thinner metal When the plate is fixed, the thinner metal plate is easy to bulge after being squeezed, which is inconvenient for the operator to drill holes and affects the drilling efficiency of the metal plate
