Drilling device of sheet material for producing machine case of computer

Abstract

The invention relates to the technical field of auxiliary devices for producing machine cases of computers and in particular relates to a drilling device of a sheet material for producing a machine case of a computer. The drilling device can be used for improving the stability of a metal sheet on a worktable; after drilling is finished, a drilling bit can be pulled out very well, a condition thatthe metal sheet is lifted upward along the drilling bit is prevented and the practicability is improved; an electric hand drill does not need to be manually held to drill, so that the manpower is alleviated; meanwhile, the utilization safety of the drilling bit is improved and the drilling effect is improved; the drilling device is convenient to operate, the potential safety hazards are reduced and the utilization safety is improved; the drilling device comprises four groups of supporting legs and a worktable, and comprises four groups of supporting columns, four groups of adjusting hand wheels, four groups of connection springs, a fixe ring, four groups of fixed rods, four groups of guide sleeves and a top plate; the drilling device further comprises four groups of supporting springs, a front toothed rail, a rear toothed rail, a left toothed rail, a right toothed rail, a front gear, a rear gear, a left gear, a right gear, a driving motor, a front reinforcing plate, a rear reinforcingplate, a left reinforcing plate, a right reinforcing plate, a pressing column, four groups of supporting sliding columns, a pressing plate, a left pull rod and a right pull rod.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for computer case production, in particular to a plate drilling device for computer case production. Background technique [0002] As we all know, the plate drilling device for computer case production is an auxiliary device used in the production process of computer cases to drill holes in metal plates so that the case can be better assembled through bolts. It is used in computer case production.

[0002] As we all know, the plate drilling device for computer case production is an auxiliary device used in the production process of computer cases to drill holes in metal plates so that the case can be better assembled through bolts. It is used in computer case production. It has been widely used in the field; the existing computer case production sheet metal drilling device includes four groups of legs, workbench and electric hand drill, the tops of the four groups of legs are connected with the left front side and the left rear side of the bottom end of the workbench respectively. , the right front side and the right rear side are connected, and the hand drill is positioned on the workbench; when the existing computer case production plate drilling device is used, first mark the punching position on the metal plate to be drilled, and then work Put the wooden board on the table, put the metal board flat on the top of the wooden board, then connect the hand electric drill to the external power supply, and manually hold the hand electric drill at the marked position to drill holes; the existing computer case production board During the use of the drilling device, it was found that the stability of the metal plate on the workbench is poor. After the drilling is completed, the drill bit cannot be pulled out well, and the metal plate is easily lifted up with the drill bit, resulting in poor practicability; In addition, manual electric drills are used to drill holes, which wastes manpower. At the same time, the support effect of manual electric drills is poor, resulting in poor stability of the drill bit, poor drilling effect, and inconvenient operation. lower
