The invention has the beneficial effects that:
1. the workpiece clamping is quick, simple and convenient, the positioning is accurate, and all bearing holes can be machined only by one-time clamping. After the headstock box body is hoisted to the workpiece mounting seat, the headstock can be quickly positioned through the workpiece positioning block and the workpiece adjusting block, and the headstock is fixed by utilizing the foundation hole of the headstock.
2. Efficient bore hole processing. The number and the positions of the output shafts of the left/right power boxes correspond to the bearing holes to be machined on the left and right sides of the headstock body one by one. Through the length design of different output shafts and the design of detachable cutter heads, a plurality of bearing holes on the same side can be simultaneously machined.
3. All shaft holes are bored through one-time clamping, the inner circle size, the coaxiality, the position degree, the verticality, the parallelism, the center distance between the shaft holes and other sizes of the shaft holes of the headstock box body can be well guaranteed, and the precision stability of batch production of box body parts is improved.
4. The left/right power boxes are fixed on the lathe bed, and the workbench is driven by a screw rod servo motor through a numerical control system to move. The numerical control system brings visual operation for the forward and backward movement of the workbench, and the accuracy of the size in the depth direction of the hole is ensured.
5. The multi-output-shaft simultaneous processing and the single-shaft numerical control system are applied to the two sides of the power box, so that the difficulty of clamping and processing operation is greatly reduced, and the dependence on high skill requirements of workers is reduced.
