Description

The invention relates to the field of machine tools, in particular to re-adjustable multi-spindle drilling heads. FROM (0). Myochosly overlaying heads with adjustable, intercenter 1M spindles distance. With the aim of automatic transfer of multiple Overlaid Goloaki, from one pitch to another three, with some holes, flush: ogee. in the case of the proposed tolO1V: K | And the spindle carriages with 1p; inols, from which the central aral base stationary and 01, the rest p.aic are bored, M | Metrically both sides of it on parallel, synchronous to the growing ones. from a single drive for moving screws , shat: And from section to section, from average to extreme, they grow in geo-metric progression with a denominator equal to two.

For the purpose of automating the installation of an intersecting floor, between the spindles, a feedback sensor with a clipping is installed on one of the movement screws. The drawing showed the kinematic scheme of the proposed tolovki. In the corpus 1 of the HEAD, there are five spindle carriages 2, the central base of which is an imp.

On the codes of the non-displacement screws. the scatteries 4 are mounted, connected through one common drive gear 5 with a box of 6 ookorgey. The other free end of one of the 1VINTAv. is displaced and the sensor is 7 ino positioned. in the head of the tank l1sta..novleny n-and supports splined shafts 8 - drive W | Pi.ndeley and 9 -

In Koipinyce of each spindle armature 2, there is a quill // with a spindle 12, a screw 13 for supplying the pinol, and a retainer M for the armature.

The drive spindle is complete with a spline connected to the mecreipHe 18 output of a conical annular container, installed by the IB carriage, this pinion gear, 19, in a BOOM line, on the spindle drive 8 shaft.

On (Screw 13, the feed, there are two cam louimufuta; Vedom.ma 20 and the leading 21, freely rotating on the drive end of the screw. The driving half coupling is also the output gear of the helical gear pair, where the driving gear 22 is connected splined shaft 9 (given

The locking mechanism 14 of the spindle carriage is spring-loaded 26 from one end, and the other end of the center.

When the heads are turned on, a mandatory automatic quick return of the pins to the initial position (as shown in the drawing) is carried out to the electrical level (not the drawing in the drawing). The movement from the motor through the speed box 6 and the gears 29 and 30 is transmitted to the splined shaft 9 of the feed.

Next, through the cog-gear gears 21 "22 and cam electric N1IT | HY1e clutches (turn on all), the movement is transmitted to screws J3 (feed and tainoles. When all the pynols are returned to their original position), the clutches and clutches are turned off - and P1inol at the end of his turn
