Abstract

The invention relates to metal cutting and can be used in aggregate machines and automatic lines. The aim of the invention is to simplify the design of the rotation mechanism of the multi-spindle head. The body of the multi-spindle head consists of two parts. The rotation mechanism is made in the form of copiers 5, mounted on the outer surface of part 2 of the body, spring-loaded dogs 6 and roller 7. Dogs 6 are mounted on part 2 of the body between the copiers 5 and can be rotated around the axes 8. Their rotation is limited by stops 9. When making a working feed the spring-loaded dog 6, interacting with the roller 7, moves away from the stop 9 and rotates around the axis 8. At the end of the working stroke, the dog 7 leaves the contact with the roller 7 and returns to its original position. When the multi-spindle head reverses, the pawl 6, resting on the stop 9, interacts with the roller 7 and the body part 2 begins to turn. During the further return stroke, the copier 5 enters into contact with the roller 7, as a result of which the final part of the body 2 rotates into the next position. 2 Il.

The invention relates to metal cutting and can be used in aggregate machines and automatic lines.

The purpose of the invention is to simplify the design of the spindle head.

Figure 1 shows a multi-spindle head at the end of the working stroke, the general view; figure 2 - view And figure 1.

The multi-spindle head contains a body made of two parts 1 and 2, one of which is intended for communication with the machine tool and the other is mounted coaxially with part i of the body so as to be rotatable. Inside the case are spindles 3, kinematically connected by means of a shaft 4 to a drive (not shown). G. Mechanical rotation of part 2 of the housing with the spindle 3 is made in the form of copiers 5, mounted on the outer surface of part 2 of the housing, spring-loaded dogs 6 and roller 7. Dog 6 mounted on part 2 of the housing between the copiers 5 can be rotated around the axes 8, however, their rotation is limited by the stops 9. A roller 7 is mounted on the rack 10 with the possibility of alternately interacting with the surfaces of the pawls 6 and copiers 5. Moreover, the roller 7 is fixed with a spring-loaded latch 11 and has the ability to rotate around the axis 12 in a plane perpendicular to the axis 2 cases, prior to its removal from interaction with copier 5. A retainer 13 is placed on the part 1 of the case, with the possibility of interaction with the moving part 2 of the case. Spring-loaded conductor plate 14 is installed on rolling pins 15 fixed in part 2 of the housing. With this rolling pin 15

installed with the possibility of fixing the I slots 16 of the table 17, on which pa; 1 moves the workpiece 18.

The spindle head works as follows.

When making a working feed, the multi-head moves to the side of the workpiece 18. In this case, the spring-loaded pawl 6, interacting with the roller 7, moves away from the stop 9 and rotates around the axis 8. At the end of the machining process of the part 1B, the dog leaves the contact with the roller 7 and under the action the springs return to their original position. With the reverse (idle) course of the multi-pin head, the pawl 6, resting on the stop 9, interacts with the roller 7 and the body part 2 begins to turn. At a further idle stroke, the copier 5 enters into contact with the roller 7, as a result of which the final rotation of part 2 of the multi-spindle head body takes place in the next position.

If it is necessary to work with one or several spindles, without rotating the housing part 2, the roller 7 is rotated around the axis 12 by removing the retainer 11 from contact with the roller 7. As a result, during operation, the housing part 2 will not turn.
