The specific embodiment
As shown in Figure 1 and Figure 2, the basic structure of S6125 type screw-thread miller comprises that roughly headstock (1), milling cutter commutation knob (2), main shaft commutate and draw (3), a main shaft (4), lathe bed (5), milling head bearing (6), bipyramid face shape milling cutter (7), slide carriage (8), milling head (9) and tailstock (10).
Technical solution of the present invention is: this device comprises that headstock (1), milling cutter commutation knob (2), main shaft commutate and draw (3), a main shaft (4), lathe bed (5), milling head bearing (6), bipyramid face shape milling cutter (7), slide carriage (8), milling head (9) and tailstock (10) several sections.On the left triangle muscle of milling head bearing (6), mill out a groove, guarantee milling head (9) switching counterclockwise, and make the β angle reach 90 °～157 °; Bipyramid face shape milling cutter (7) upset is contained on the milling head (9) for 180 °; The milling cutter knob (2) that commutates is pulled right position, make main motor counter-rotating, bipyramid face shape milling cutter (7), main shaft (4), slide carriage (8) meeting are simultaneously oppositely, advance the main shaft commutation to draw again (3), main shaft (4), slide carriage (8) will recover forward, have only bipyramid face shape milling cutter (7) counter-rotating, satisfy the cutting needs.At this moment, this device can be finished the processing of helical angle greater than 23 ° right hand helix groove.
Elaborate with regard to technical scheme below.
The position and the direction of motion of main shaft (workpiece), slide carriage and milling cutter when Fig. 3 is S6125 type screw-thread miller processing right-hand worm.As can be seen, because knife rest might be run into the P point of milling head bearing during clockwise by switching, make that milling head switching angle can not be greater than 23 °.That is to say that the maximum lead angle of this lathe workpiece when the processing right-hand worm can not be greater than 23 °.
Fig. 4 is us through the further investigation to S6125 type screw-thread miller, has finished processing greater than 23 ° of right-hand worms by following scheme method:
