Preferably, described punching press locking device comprises two hydraulic cylinders, and the leading portion of described hydraulic cylinder is provided with the locking head that pins bar; Simple punching press locking device.
Preferably, described locking head front end is provided with the circular groove suitable with bar; Increase contacts with bar.
Preferably, the angle between described two hydraulic cylinders and the horizontal plane is respectively 45 degree, 135 degree; Can clamp bar preferably.
Preferably, described tool rest is provided with at least three knife rests; Need to use minimum three in the process cutter.
Preferably, also comprise automatic feeding, described automatic feeding is arranged on the left end of lathe; Effectively increase work efficiency, realize automation processing.
A kind of spool processing method may further comprise the steps successively:
A. clamping device clamps bar, and the bar extension elongation adds allowance for spool length, and the lathe spindle rotation uses the drill bit on the tool rest to bore a circular blastopore in the bar end;
B. tool rest changes the groove cutter, has cut annular groove at the front end of bar, cuts a holddown groove at the bar tail end that stretches out again;
C. main shaft stall, the punching press locking device starts, and hydraulic cylinder orders about locking head forward, and locking head is stuck in the holddown groove, and the hydraulic pressure tailstock is washed into the hexagonal endoporus with circular blastopore;
D. the locking head of punching press locking device leaves holddown groove, and main shaft starts, and switches to screwer on the tool rest, the bar rear portion machining screw of stretching out;
E. tool rest switches the groove cutter, along holddown groove bar is downcut, and the spool that obtains processing, the main shaft stall, automatic feeding is fed forward bar.
Preferably, described allowance is the 1-2 millimeter; For holddown groove leaves surplus.
Compared with prior art, advantage of the present invention is: for once locate, improved the dimensional accuracy of spool, there is not fabrication hole in spool after the processing simultaneously, has improved the life-span of spool, is not easy to produce the problem of gas leakage yet, a workman can operate many machines simultaneously, has saved human cost.
