Automatic multiaxis of the present utility model mills the groove of screw tap machine compared with prior art, because multiaxis is arranged, the screw tap of a plurality of grooves to be processed can be installed at every turn, but multiaxis carries out simultaneously during calibration, the indexing accuracy height, very convenient, good operation, easy to control, time saving and energy saving, improve operating efficiency, reduced labour intensity and processing cost, and can realize multitool control.
Description of drawings
Fig. 1 is the plan structure schematic diagram of the utility model specific embodiment;
Fig. 2 is that schematic diagram is looked on a left side shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2: 21 is headstock, and 9 is tailstock body, is installed on the frame, on frame.In the inboard of headstock 21, by parallel first main shaft 1, second main shaft 2 and the 3rd main shaft 3 of being equipped with of bearing, the external end head of each main shaft is equipped with anchor clamps 6, on tailstock body 9 parallel be equipped with three to six top 8, top 8 corresponding one by one with anchor clamps 6.Each top 8 connects a top cylinder 10 that joins with Pneumatic controller that is fixed on the tailstock body 9.During work, an end of screw tap 7 matches with anchor clamps 6, and the other end is by top 8 supportings.
All be fixedly connected with intermeshing travelling gear 4 on each main shaft in the headstock 21, guarantee that three main shafts rotate simultaneously or stop by key.
Termination at the 3rd main shaft 3 is fixedly connected with spacing driving gear 12 and is set with change gear 11 by key, is processed with the adjustment hole 22 and the rectilinear slotted hole 23 of arc on change gear 11.Intermediate speed pinion 25 and gear broad in the middle 26 are conjoined structure, are installed in slotted hole 23 places by jackshaft 24.Rotating shaft 29 is installed on headstock 21, spacing driven gear 27 is installed in the rotating shaft 29 and is the position-limited wheel 28 of conjoined structure with it, periphery place at position-limited wheel 28 is connected to limiting stand 18, wherein spacing driving gear 12 and intermediate speed pinion 25 engagements, gear 26 broad in the middle and spacing driven gear 27 engagements.Adjusting the 22 pairs of change gears 11 in hole, intermediate speed pinion 25 and gear broad in the middle 26 by the fastening bolt utilization positions.
