Abstract
The invention discloses a center hole drilling device capable of preventing axial movement. The center hole drilling device comprises a machine tool bed. A drilling platform is arranged on the machine tool bed. A power mechanism for driving a shaft workpiece to rotate is arranged on the drilling platform. A rotary sleeve is externally hung at the output end of the power mechanism. The shaft workpiece penetrates through an inner ring of the rotary sleeve. An expansion sleeve used for expanding is also arranged between the inner ring of the rotary sleeve and the shaft workpiece. A supporting frame is further arranged on the drilling platform. The power mechanism is vertically arranged on the supporting frame. The two ends of the drilling platform are each provided with a center drill clamping seat for carrying a center drill. Each center drill clamping seat is further provided with a triangular chuck for clamping the center drill. Two fixed plates for protecting the shaft workpiece against axial movement is also arranged on the drilling platform. The two fixed plates abut against shaft shoulders on the two sides of the shaft workpiece correspondingly. Through the center hole drilling device, center holes are drilled at the two ends of the shaft workpiece while the shaft workpiece is driven to rotate, and secondary clamping is not needed. The drilling efficiency and the drilling precision are both substantially improved.
Description
Technical field
The present invention relates to a kind of perforating device, and in particular to a kind of centre bore punch device for preventing axial float.
Background technology
For axial workpiece in prior art, its two ends generally requires centering, and the existing centre bore punch device for preventing axial float, 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 centre bore punch device for preventing axial float, it is possible to increase centre bore perforating efficiency.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
