The aim of the invention is to reduce the power of the drive for changing the multiple-spindle boxes and to improve the conditions of service for the store of the multiple-spindle boxes.

On fng. 1 but shown machine with interchangeable multi-spindle boxes, general view; in fig. 2 - top view of the machine and the position of the box, ready to change; in fig. 3 - version of the machine with two screw monorails; in fig. 4 - a variant of the machine in which the change of boxes occurs by a separate operator outside the processing area; in fig. 5 — unit for fixing the box and turning on the drive of the main movement; in fig. 6 - box stopper; in fig. 7 - operator with a box stopper; in fig. 8 is an example of a turnout; in fig. 9 shows, on an enlarged scale, the connection of the rail section with the lower branch; in fig. 10 - lever mechanism; in fig. 11 is a view A of FIG. 2; in fig. 12 is a view B in FIG. 4, an operator version for changing boxes outside the treatment area; in fig. .13 - section BB of FIG. 12.

The workpiece (Fig. 1-4) is fixed on the turntable 1. On the contrary, there is a power table 2 (Fig. 1-4) with a headstock 3 (Figs. 1-4, 9 and 10). The multi-spindle box 4 is secured to the grandma by gripping 5 (Fig. 1 and 5) by the guides 6. In the upper part of the multi-spindle box there is a suspension consisting of a pair of rollers 7 (Figs. 1, 2, 4 and 9) mounted on the cantilever pillars. The box store contains a screw monorail 8 (Figures 1-4, 8, and 1G) fixed to metal structures 9 (Figures 1-4, 8, 9, and 11). An operator 10 is installed in the upper part of the metalwork (Figures 1-3, 9 and 7) carrying a rail section 11 (Figures 1, 2, 4,

7k 9), made in the form of a section of the main monorail. The upper branch of the monorail 12 is on the same radius R (Fig. 2) with the lower branch 13 (Figs. 2, 4 and 9). Monorail 8 may have a branch 14 (Fig. 1 and 8). The monorail can also be made in the form of separate turns 15 and 16 (Fig. 3).

In this case, the box to the headstock is fastened by vertically arranged guides 17, and the next box is in position 18. In another embodiment of the machine (Fig. 4), the operator. 19 (Fig. 4, 12 and 13) with a section of the path is located offset from the treatment area. A set of boxes 20, ready for a shift, stands on a monorail and is held by constraints 21 and 22 (Fig. 1). The gripper 5 is controlled by a lever mechanism 23. Drufe

A second lever mechanism 24 (Fig. 5 and 10) is associated with a quill bearing a cam drive shaft — a spindle (not shown). Capture 5 has two rolling pins 25.

The operator 10 (Fig. 7) has a stopper 26 (Fig. 7, 9 and 12) with an electromagnetic drive. A variant of the machine with a branch 14 contains a switch assembly 27 (FIGS. 8 and 11) with rail sections 28 and 29 (FIG. 8) The switch assembly 27 has an actuator 30

10 (FIG. 2), and operators 10 and 19 are the drive 31 (FIG. 1-3).

The machine works as follows.

The workpiece is installed

on the rotary table 1. To spindle

grandma 3, mounted on the power table 2,

 Attached is a replaceable multi spindle box. For this purpose, the limiter 22 (Figs. 1 and 2) is raised on command and the front is separated from the set of boxes 20. It moves along a monorail (on a slope) to section 11 (Fig. 7) of operator 10 and stops at stopper 26. When box 4 is installed on section 11, guides 6 enter gripper 5. Operator 10 is lowered so that the profile of section 1 1 out of the same25 Lobov rollers 7 suspension box. The removable box released from contact with section 11 lies on the claw 5 and the mechanism 23 (FIG. 5) is pressed against the spindle head 3. Then, the lever device 24 rotates the quill with the cam drive shaft (not shown). The cam shaft engages with the cam shaft of the multi-spindle box. Coupled camshafts are given rotation, transmitted by the box spindle. Power table 2 moves in the direction of the part, it is processed and the table is returned to its original position. During the processing of the part, limiter 21 releases the set of boxes 20 and they move to the limit of 40.

After returning from the 1-step tailstock with the box to its original position, it is released and moved out of the treatment area.

, To release the co-driver, rotate the lever mechanism 23 and pull the clamp 5 away from the box. The box is decompressed. The operator rises until the rollers 7 are touched by the section 1 1, after which the stopper 26 is removed and a multi-spindle

50, the box (on the slope of section 11) is moved as far as it will go to a stopper (not shown). The operator then moves the multi-spindle box up and stops in one of two positions. One of the provisions is when section 11

55 is mounted uniaxially with branch 12. In this case, the multi-spindle box rolls along the monorail to a stop on the stopper 21. In this case, it is 30

The back of the store is maximized in the processing of degas. w involved a large number of many spindle boxes.

In another case, when the machine is operated with a limited number of multi-spindle boxes d. 1 of their transportation, a shorter path is used through branch 14 with the lower part of the monorail, including branch 13. In this case, using a switch 27, the monorail 29 is closed with branch 14.

When section 11 stops uniaxially opposite branch 14 along section 11 slope (with the stopper removed), the multi-spindle box rolls down into section 29 {closed monorail and branch) and DS,;: its monorail - until it stops at limiter 21. The next spent box is delivered the same in a way. With such a path (path) of multi-spindle boxes, the upper branch of the monorail 12 is free and can be used as a warehouse for storing other sets of multi-spindle boxes. For the transfer of multi-spindle boxes from the warehouse, the turnout switch closes the monorail 28 section 11. The machine's multi-spindle box can also be made in the form of several unclosed helical turns 15 and 16 (Fig. 3). In this case, only one set of multi-spindle boxes can be placed on each turn.

The boxes are fed as follows.

Operator 10 rises to align its section of path 11 with the lower branch of one of the monorails 15 or 16. Multi-spindle box 18 rolls down

the operator section 11 and the operator down.

In order to grip the box, its guides 17 are arranged vertically. The box mounted on the base is clamped.

After the end of the machining cycle, the multi-spindle box is raised by the operator to the position where the operator’s path section becomes uniaxial with the upper branch of the monorail 15 or 16. Each monorail is fitted with limiters of type 2 and 22.

A multi-spindle box shop, made with the operator moving away from the axis of the power units, is shown in FIG. four.

Multi-spindle boxes are fed as follows.

The next multi-spindle box (Fig. 4), located on branch 13 (on the limiters 21 and 22), is released 0 and rolled down onto section 11 pivotally suspended on the headstock. Section 11 is lowered by an amount sufficient to base the box on a single tailstock. The box is clamped, the table travel with the box, the machining of the part and the return of the box with the headstock. Section 1 is extended by an amount sufficient to unlock the box. The box on the slope of section 11 rolls down onto the section of the operator's path 19. When the box from section 11 goes to section 19 of the operator, the next box moves from the branch 13, which takes its place, to section 11. Simultaneously moving the two boxes reduces the change time of the spindle our boxes. From operator section 19 by operator 10, the box is sent to the upper branch of the monorail 2.
