21 fpUB.f The invention relates to metal-rabs; namely, to spindle assemblies of multi-position diamond boring machines. The purpose of the invention is to increase labor productivity by reducing the time spent on the activation of the division mechanism. FIG. 1 shows a spindle assembly, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 - view B on .fig. five; in fig. 5 is a sectional view BB in FIG. four; in fig. 6 is a view of Fig. 3. In case 1, shaft 3 is placed on bearings 2. On flange of shaft 3, case 4 is fixed. In eccentric bore 5 of case 4, spindle 6 is mounted with the base elements of workpiece 7. A separating disk 8 is fixed on the spindle. The casing 4 has a movable clamp 9, which interacts with the spring 10 installed in the glass 11. On the spindle of the spindle 6 there is a gear 12, constantly engaged with the gear rim 13, made on the car 14, 14 on the glass 11 A collar 15 is made, which is placed in a cylindrical groove 16 tons of gi 14. A hydraulic cylinder 18 is connected to the shaft end 3 on rolling bearings 17 and connected to thrust 14 via bearings 19. Gear 20 with rounded teeth is fixed at the left end of the string 14. The housing 1 on the bracket 21 is equipped with a dividing mechanism 22, consisting of a hydraulic cylinder 23 with a rod rack 24 engaged with a gear shaft 25 A gear 26 with rounded teeth is mounted on the gear shaft 25. A bracket 27 is fixed on the housing 1, bearing a hydraulic cylinder 28, on the stem of which a cracker 29 is mounted, which is included in the groove of the pulley 30 mounted on the shaft 3. The spindle assembly works as follows. Initially, the spindle 6 is oriented in an angle, and through the hydraulic cylinder 18, the retainer 9 is inserted into the slot of the separating disk 8. The workpiece 7 is installed in the fixture placed on the spindle 6 and oriented so that one of the pre-machined holes turns along the axis of rotation of shaft 3. pressing the button Cycle shaft 3 is associated with rotation at a speed that provides the desired cutting speed. The cutter processes the entire profile of one hole of the workpiece 7 from one installation. Shaft 3 stops. By means of the hydraulic cylinder 18, the driving gear 14 is moved back together with gears 13 and 20. Gear 20 engages with gear 26. This is possible in any angular position of shaft 3, since gear 20 is located along the axis of the hole. At the same time, the shaft 3 rotates together with the thrust 14, which makes it possible to engage the gear 20 in engagement with the gear 26. With further progress, the ha ha 14 pulls the cup 15 backwards 11 back, releasing the spindle 6 in the corner. After that, the shaft 3 is braked in angle by means of the hydraulic cylinder 28 through the cracker 29, which interacts with the pulley 30 mounted on the shaft 3; Then, the dividing mechanism 22 by moving the rail 24 with the help of the hydraulic cylinder 23 through the gears 25, 26, 20, 13 and 12 rotates the spindle 6 relative to the braked shaft 3 by the required angle. After that, the hydraulic cylinder 18 moves the gy 14 together, with a glass 11 to the latch's depression, into the slot of the separating disk. At this point, the hydraulic cylinder 28 removes the cracker 29 from the pulley 30, thereby disengaging the pulley. Next, the next hole cycle is repeated. Thus, it is not necessary, after each cycle, to rotate and index the shaft to ensure engagement between the kinematic division chain mounted on the shaft, and the rotation mechanism mounted on the fixed part.
