Conveniently-adjusted drilling machine with protection function

Abstract

The invention relates to a conveniently-adjusted drilling machine with a protection function. The conveniently-adjusted drilling machine comprises a base, a top plate, a fixing mechanism and a drilling mechanism; the fixing mechanism comprises two sliding plates and two stretchable assemblies, each stretchable assembly comprises a fixing plate and two stretchable units, and each stretchable unit comprises a driving unit, a movable block, a fixing block, a stretchable support and two connecting rods; and the drilling mechanism comprises a lifting table, a drilling assembly and two adjusting assemblies, the drilling assembly comprises a drilling machine, a convex plate and four protection units, and each protection unit comprises a first motor, a bearing, a first driving shaft, a wire coil,a pull wire, a protection plate and a hinge unit. According to the conveniently-adjusted drilling machine with the protection function, the distance between the two sliding plates is flexibly controlled through the fixing mechanism, and workpieces in various body shapes can be conveniently placed for fastening; and in addition, when the drilling mechanism is used for drilling, the four protectionplates are used for shading, drilling chippings are prevented from splashing, safety of an operator is protected, and the practicability of the drilling machine is improved.

Description

technical field [0001] The invention relates to the field of hardware accessories production equipment, in particular to a drilling machine with protection function which is convenient for adjustment. Background technique [0002] Drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target to leave a cylindrical hole or hole on the target by means of rotary cutting or rotary extrusion. Also known as punching machine, drilling machine, through hole machine and so on. The desired effect is achieved by drilling precision parts. [0003] When the drilling machine is drilling the target workpiece, in order to prevent the workpiece from shaking, it is usually necessary to fix the workpiece, and the workpiece can be fastened by placing the workpiece inside the fixing device, but in this way, the drilling machine Only some workpieces smaller than the fixing device can be drilled, and for some large workpieces, because ...

Problems solved by technology

[0003] When the drilling machine is drilling the target workpiece, in order to prevent the workpiece from shaking, it is usually necessary to fix the workpiece, and the workpiece can be fastened by placing the workpiece inside the fixing device, but in this way, the drilling machine Only some workpieces smaller than the fixing device can be drilled, and for some large workpieces, because they cannot be placed in the fixing device, the equipment cannot process them. Not only that, but during the drilling process, as the When the drill bit rotates, various debris splashes near the drill bit, and the debris is easily splashed on the human face, which brings safety hazards to the operating workers, thereby reducing the practicability of the existing drilling machine
