Punching positioning device

Abstract

The invention discloses a punching positioning device, and belongs to positioning devices. The punching positioning device is characterized by comprising a main body, supporting columns and sucking discs. The main body comprises an upper main body and a lower main body, one end of the upper main body is hinged to one end of the lower main body through a rotation shaft, the other end of the upper main body and the other end of the lower main body are respectively provided with a connecting plate, the connecting plates are connected through a fastening bolt, the end portions of the supporting columns are respectively provided with one sucking disc, each supporting column comprises a movable supporting column body, a fixed supporting column body and a spring, the springs are arranged in hollow inner cavities of the movable supporting column bodies, the tail ends of the fixed supporting column bodies are inserted into the positions, outside the springs, of the hollow inner cavities of the movable supporting column bodies, the sucking discs are arranged at the front ends of the fixed supporting column bodies, and the tail ends of the movable supporting column bodies are connected with a main body. The punching positioning device has the advantages of guaranteeing that a drill bit of an electric drill does not generate offset and stays at one point all the time, guaranteeing the accuracy of the punching position, being capable of generating no vibration, being capable of causing no vibration damage on adjacent equipment, being capable of causing no malfunction, being capable of causing no drill bit annealing, prolonging the service life of the electric drill and the like.

Description

technical field [0001] The invention relates to a positioning device, in particular to a punching positioning device for punching electric energy meter screens by a pistol-type electric drill. Background technique [0002] When installing the electric energy meter and junction box on the electric energy meter screen, it is necessary to use a pistol-type electric drill to drill holes on the electric energy meter screen. Because the steel plate is smooth and hard, the drill bit often slips and the drill hole deviates from the predetermined position. In order to prevent the drill bit from slipping, it is generally necessary to use a hammer or a punch to locate the hole at a predetermined position before drilling; or reduce the speed of the electric drill and proceed step by step. However, positioning on the screen with a hammer or a punch will inevitably cause vibrations, which may cause vibration damage to adjacent equipment and even cause malfunctions; and lower the speed of ...
