Description

And: the invention relates to metal cutting, in particular to machining on metal-cutting machines with automatic tool change,

The purpose of the invention is to simplify the machine design due to the elimination of intermediate transnort-oriented mechanisms,

FIG. 1 shows a machine, top view; on fi1, 2 - the same, side view; in fig. 3 - a box with a box in the but; (installation on the bottom head.

The power table 2 on which the shnindel- on the headstock 3 with the mechanism for fixing the replaceable spindle boxes 4 is mounted on the machine bed 1, the power table 6 with the fixture 7, in which the workpiece 8 is fixed, is fixed on the cross-bed 5, mounted over the power table 2 with the spindle head 3, there is a rotary-mounted magazine 10 of the clutch boxes 4, including a pivoting and dividing one hundred, t 11 and fixedly fixed,: 1 relative to,: 1 suspensions cTO,: ia suspensions 12, on which pairs are installed parallel rolling pins 1 3 with spindle boxes mounted on them 4.

Shnindelnye boxes 4 have basic elements, made in the form of tongs 14 with T-shaped 1) 1 grooves, located in the plane of rotation of the magazine 10. In Nsindend, 1 pinch 11, the headstock 15 has a mechanism for fixing the boxes 4 with tubes 15, which - in accordance with the choice of clamps 15 in one, 1 box 4, Spindle box 4 is suspended in the store 10 on the suspension 12 to the pre-oriented locking, yuzhen and n on two rolling pins 13 by means of the basic screwdriver: the spindle box 4. The tailstock 3 is also equipped with a half coupling 16, and a single box 4 is driven oh half coupling 17.

The machine works as follows.

1, after mounting and securing the part 5 in the attachment: 1, 7, by turning the magazine 10, the required spindle box 4 is fed to the shift position and stopped. When the magazine is new 10, the basic elements of the box describe the arc, bending around the spindle head 3, while the bolts 15 of the locking mechanism fit into the T-grooves of the tongs 14.

The locking mechanism works, the gigs 15 interact with the tongs 14 and move the spindle box along the rolling pins 13 in longitudinal direction, and this happens at the same time, the orientation and clamping on the headstock 3 occurs, as well as the inclusion of the Hi and 17 coupling halves.

Then the spindle head 3 together with the hinge, the 1st box 4 is moved by the force cTo, ioM 2 and the transverse direction at a slower speed, then at the working feed. When you do not go to the worker.) Spindle feed box 4 nnvvods ts in rotation from the spindle,: 1 grandma 3 through the semi-clutch 16. and 17. Occurs | | In c; iy-5, the NC of the milling operations of the spindle head 3 together with the spindle box 4 (the milling head) is fed forward to the required direction, fixed and fixed, and the feed movement is carried out by the power table 6. By means of processing 5, the thread head 3 is retracted into position of the shift of the spindle boxes 4.
