Abstract
The invention discloses a multi-purpose center hole drilling tool. The multi-purpose center hole drilling tool comprises a lathe bed, a drilling platform is arranged on the lathe bed, a power mechanism driving a shaft workpiece to rotate is arranged on the drilling platform, a rotating sleeve is externally hung on the output end of the power mechanism, the shaft workpiece penetrates the inner ring of the rotating sleeve, an expansion sleeve used for expansion is arranged between the inner ring of the rotating sleeve and the shaft workpiece, a supporting frame is arranged on the drilling platform, and the power mechanism is vertically arranged on the supporting frame; center drill clamping bases for containing center drills are arranged on the two ends of the drilling platform, triangular chucks used for clamping the center drills are arranged on the center drill clamping bases, linear guide rails are arranged on the drilling platform, and the center drill clamping bases are arranged on the linear guide rails. Center holes are punched in the two ends while the shaft workpiece is driven to rotate, secondary clamping is not needed, and the drilling efficiency and the punching precision are greatly improved.
Description
Technical field
The present invention relates to a kind of perforating device, and in particular to a kind of multi-purpose center's hole drill hole tool.
Background technology
For axial workpiece in prior art, its two ends generally requires centering, and existing multi-purpose center's hole drill hole tool, mostly engine lathe, during punching, first by the chuck clamping of axle one end, then, installation center hole drill centralized positioning is carried out on tail stock again, start lathe after adjusting, lathe chuck drives shaft member to rotate, then tailstock is moved to appropriate position, swinging handle afterwards, centre drill is made to start punching, after punching terminates, mobile tailstock, take out workpiece, turn around to reinstall and punch, for long-axle workpieces, during centering, also need to set up bracket, prevent workpiece bows, therefore, existing drilling method and punch device, operation is various, drilling precision is low, during for batch machining shaft-like workpiece, it is less efficient, it is badly in need of a kind of equipment that can improve perforating efficiency.
The content of the invention
In view of this, it is an object of the invention to provide a kind of multi-purpose center's hole drill hole tool, it is possible to increase centre bore perforating efficiency.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
A kind of multi-purpose center's hole drill hole tool, including lathe bed, on the lathe bed, drilling platform is set, the actuating unit for driving shaft-like workpiece to rotate is provided with the drilling platform, rotary sleeve is hung with outside the actuating unit outfan, the shaft-like workpiece passes through rotary sleeve inner ring, the expansion sleeve for swelling is additionally provided between the rotary sleeve inner ring and shaft-like workpiece, bracing frame is additionally provided with the drilling platform, the actuating unit is vertically arranged on bracing frame, the two ends of the drilling platform are provided with the centre drill grip slipper for placing centre drill, the triangle chuck bored for Clamping Center is additionally provided with the centre drill grip slipper, line slideway is additionally provided with the drilling platform, the centre drill grip slipper is arranged on the line slideway.
Further, the actuating unit is air motor, and the rotary sleeve is arranged at air motor outfan.
Further, in door type structure, the actuating unit is arranged on the top of bracing frame to support frame as described above, and support frame as described above is removably arranged on drilling platform.
Further, the drilling platform two ends are additionally provided with centre drill grip slipper limited block.
Further, the support adopts cast iron materials integrally casting shaping.
The beneficial effects of the present invention is：The present invention in its two ends centering, is increased dramatically without the need for secondary clamping, drilling efficiency and drilling precision while shaft piece rotating is driven.
