Abstract

The invention relates to machine tools and can be used in aggregate milling machines. The purpose of the invention is to increase productivity and simplify the design. The milling headstock includes a quill 1, which can be moved in the hull 2. At the front end of the quill, there is a driver element 4 attached to the slider 3. The quill bounce 1 is carried out by means of a rebound hydraulic cylinder 5. Hydraulic cylinders 6 serve for clamping quill 1s. The forward position of the milling cutter 7 is determined by means of the stop 9. The stop is fixed on a rotary rod placed in the hydraulic cylinder. On the rod is installed with the possibility of rotation at a certain angle plate with bevels on the ends. At the ends of the covers at the angle of rotation, the projections are made with bevels interacting with the ends of the plates. The planes of the bevels on the covers and on the ends of the plates are parallel to each other. 1 hp f-ly, 5 ill.

Description

The invention relates to a machine tool and can be used in agate milling machines.

The purpose of the invention is to increase productivity and simplify the design, and by eliminating intermediate periods when adjusting the cutter to size, country of spring-loaded caliber and its clamping mechanism, making the angle of bevel within the self-locking angle. Figure 1 shows the milling headstock, a longitudinal section; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2; Fig. 4 shows a section B-B in Fig. 3; 15 in Fig. 3 shows a scan of the mechanism for turning the additional stop along the diameter d.

The milling headstock contains a quill 1 placed with the possibility of axial ne-20 displacement in the housing 2 and connected with the slider 3 by means of a driver element 4 fixed on the front end of the quill 1. The quill rebound 1 is carried out by the rebound clamp 25 5 is produced by hydraulic cylinders 6 clamping quill. The forward position of the milling cutter 7, mounted on the spindle 8 mounted in quill 1, is determined by the stop JQ 9 fixed on the pivot stem 10 of the mechanism for turning the additional stop 9 to the cutter 7 when it is adjusted to the size. The emphasis is placed on the swiveling rod 10 of the hydraulic cylinder with the front 11

and rear 12 covers, a sleeve 13, a housing 14 and a swivel plate 15 Front 11 and rear 12 covers in the area of rotation of the stop 9 with angle e

They are equipped with protrusions 16 with bevels having the same y in the bevel angle, made within the limits of the self-locking angle. The ends of the plate are made with bevels. The planes of the ends of the plates are parallel to the planes of the bevels of the Cruszek projections. 45

Setting the cutter to size when replacing it is carried out as follows.

A new mill 7 is attached to the spindle nose 8. By applying pressure to the rod end of the hydraulic cylinder 5, the -. from the rebound pintles 1. Then the pressure is supplied to the cavity G of the mechanism for turning the additional stop 9 to the milling cutter 7 when it is adjusted to the size made in the form of a hydraulic cylinder with a rotary rod. At the same time, simultaneous rotation and supply of the stop 9 is carried out due to the interaction of the plate 15 with skewed protrusions 16 Krschhek P and

12, By applying pressure to the rodless cavity of the hydraulic cylinder 5, quill 1 is brought in to the contact of the teeth of the milling cutter 7 with the stop 9, while the milling cutter 7 takes the nominal position.

Then, quill 1 is clamped by hydraulic cylinders 6. After this, a simultaneous reverse rotation and retraction of the stop 9 from the milling cutter 7 is carried out. when pressure is applied to the cavity D of the mechanism for turning the stop 9 to the cutter 7 when it is adjusted to the size. All of the above transitions are carried out automatically.
