Detailed ways

As shown in Figures 1 and 2, the utility model automatic tap groove milling machine includes a bed, a column 1, a spindle box 2, a motor, an indexing head 6, a tail tip 3, an automatic feeder 4, a fixed workbench, a sliding Workbench 5; column 1 is installed on the bed, there is a vertical guide rail on column 1, a sliding body 8 is installed on the vertical guiding rail, there is a longitudinal guide rail on the sliding body 8, and the headstock 2 is installed on the longitudinal guide rail of the sliding body 8, The motor is installed on the spindle box 2; the fixed workbench is installed on the bed, and there is a horizontal guide rail on the fixed workbench, and the sliding worktable 5 is installed in the horizontal guide rail; the indexing head 6 and the tail center 3 are installed on the sliding worktable 5, Automatic feeder 4 is fixed on bed or fixed workbench.

Preferably, the vertical guide rail on the column 1 is a rectangular or dovetail guide rail, the sliding body 8 is driven by the screw nut 7 in the vertical direction, and the sliding body 8 can also be driven by a worm gear or a motor. In the longitudinal direction, the longitudinal guide rail on the sliding body 8 is a dovetail guide rail, and the headstock 2 on the sliding body 8 is driven by a screw. In order to adapt to the processing of taps of different specifications, the motor is preferably a variable frequency motor.

The sliding workbench 5 is connected to the oil cylinder, and is driven by the oil cylinder to move laterally left and right, and may also be driven by a motor.

As shown in FIG. 2 , the main shaft 14 is driven by a motor via a primary shaft and an intermediate shaft. It can also be two-axis or multi-axis transmission or direct drive by motor.

As shown in Figure 3, the indexing cam 10 of the indexing head 6 is fixed on the indexing shaft 12, the indexing shaft 12 is supported in the box by two bearings, and the slider 9 is directly connected with the piston of the indexing cylinder 13 , The eccentric pin 11 is installed on the slider 9, and the bumper 15 is installed on the eccentric pin 11. When working, the piston rod of the indexing cylinder 13 drives the slider 9 to move to the right, and the slider 9 drives the eccentric pin 11 to move to the right along the straight line of the indexing cam 10. The screw hits the bumper 15 on the eccentric pin 11, so that the eccentric pin 11 rotates into the next indexing groove of the indexing cam 10. At this time, the electrical switch controls the piston rod of the indexing cylinder 13 to move to the left, so that the eccentric pin 11 pushes The helical curved surface of indexing cam 10 is tight until the bottom of the groove, and completes indexing. The indexing head 6 has a simple structure, and can easily realize arbitrary equal division of the circumference by replacing the indexing cam 10 .

The automatic feeder 4 is equipped with a feeding oil cylinder and a stepping oil cylinder, and the two cylinders move independently without affecting each other. When working, the feeding cylinder quickly sends the workpiece to the mechanically limited position, then the stepping cylinder lifts and steps into the feeding bracket. After the top and the indexing head are pressed against the workpiece, the stepping cylinder reverses and the feeding bracket falls And return to the original position, at this time, the feeding cylinder moves in reverse to make the automatic feeder return quickly.

When milling the tap groove of the utility model, after the automatic feeder sends the tap to be processed to the position, the indexing head and the tail tip clamp the tap, the worktable advances, and the first groove is processed. After completion, the workbench retreats, and the indexing head Indexing, the worktable advances to process the second groove, and so on, until the set number of grooves is processed, the indexing head and tail center are released, and the workpiece falls into the receiving box. Then proceed to the processing of the next workpiece.
