Technical Field
The utility model relates to the technical field of machining, specifically a circular cutting tool for deep hole terminal surface.
Background
In some workpieces, the interior of the workpiece needs to be machined to form a deep hole, for example, in the workpiece shown in fig. 1, a high-frequency compression spring needs to be installed at the core part of an extension bracket 1, in order to improve the working stability of the spring, the outer circle of a spring positioning mandrel 3 and a supporting surface 2 need to be cold-machined to improve the precision, and because the depth is too large, the existing tool is difficult to machine, so a special tool needs to be designed for production.
SUMMERY OF THE UTILITY MODEL
The utility model provides a circular cutting tool for deep hole terminal surface can the effectual technical problem who exists in the above-mentioned background of solution.
In order to achieve the above object, the present invention provides the following technical solutions:
a circular cutting tool for the end face of a deep hole comprises a tool shank, a square tool and a tubular tool bar; one end of the cutter bar is provided with a raised welding groove I, the end part of the other end of the cutter bar is provided with an installation clamping groove, the other end of the cutter bar is also provided with a screw hole communicated with the clamping groove, the square cutter is inserted into the installation clamping groove, a screw is installed in the screw hole, and the screw props against the square cutter; one end of the cutter handle is provided with a second raised welding groove, the second welding groove is provided with an assembly mandrel which forms an integrated structure with the second welding groove, the assembly mandrel is inserted into one end of the cutter rod, and the second welding groove abuts against the second welding groove and is welded together with the second welding groove.
Preferably, the intermediate portion of the shank is cylindrical in shape.
Preferably, the other end of the knife handle is provided with a clamping handle which forms an integrated structure with the knife handle.
Preferably, the length of the square knife is greater than that of the mounting clamping groove.
Preferably, the cutter bar is a seamless steel pipe.
The beneficial effects of the utility model reside in that:
the utility model has the advantages that the cutter bar is designed into the seamless steel pipe, the hollow cutter bar design reduces the self weight of the cutter, and the installation is convenient; the installation clamping groove and the square cutter are designed independently, so that the replacement is convenient, the adjustment of the processing range is convenient, and the flexibility is increased. The utility model relates to an ingenious, the processing of the turning deep hole of being convenient for.
