Description
Technical field
The present invention relates to small-hole-distance multi-hole tapping device, relate in particular to the tapping processing that No. one time clamping tapping part is accomplished the aperture distance through the automatic switchover of two stations.
Background technology
It is the technical barrier of this area that the small-hole-distance multi-hole tapping is accomplished in a clamping.
The minimum centers-distance of its tapping axle of porous tapping machine of purchasing in the market is all greater than 25mm; Many screws of panel beating tapping part involved in the present invention; Its minimum screw centre-to-centre spacing has only 12mm; Obviously adopt ready-made porous tapping machine can not accomplish a clamping tapping of whole screws, the purpose of using the porous tapping machine is to improve working (machining) efficiency, and the tapping that clamping can be accomplished whole screws is particularly important.
Prior art needs screw centre-to-centre spacing in the tapping part is processed greater than the screw of 25mm in advance; Adjusting the centre-to-centre spacing of tapping machine tapping axle has again attacked remaining screw; Promptly; Less than the tapping that need make two bites at a cherry of the screw of 25mm centre-to-centre spacing, twice tapping needs twice clamping to accomplish or on two tapping machines, accomplish, and working (machining) efficiency is lower.
Therefore, those skilled in the art be devoted to develop a kind ofly overcome above-mentioned defective, be used for aperture apart from many screws on a porous tapping machine through automatic conversion work step, one time clamping workpiece is accomplished the small-hole-distance multi-hole tapping device that whole screw tapping are processed.
Summary of the invention
The object of the invention is exactly to provide a kind of simple in structure for the defective that overcomes above-mentioned prior art existence, and is easy to operate, the small-hole-distance multi-hole tapping device that the tapping process reliability is high.
The object of the invention can be realized through following technical scheme: a kind of small-hole-distance multi-hole tapping device; It is characterized in that; This small-hole-distance multi-hole tapping device comprises bed frame device, porous tapping-head, portable tapping clamp device and tapping axle selecting arrangement; Described porous tapping-head, portable tapping clamp device and tapping axle selecting arrangement are installed on respectively on the bed frame device, wherein:
