Abstract

The invention relates to a machine tool industry and can be used in machine tools containing turning-dividing devices. The aim of the invention is to reduce the size and expansion of technological capabilities by eliminating the individual power drive of the workpiece clamping mechanism. When installing the workpiece in the clamping mechanism, the shaft 2 occupies the extreme right position. This is achieved by moving the gear 1 to the left as far as it goes to the end surface of the retaining ring 3. The resulting gap b is selected by the spring 13, with the protrusion 11 of the sleeve 12 located on the protrusion of the cylindrical end 9 and the shaft 2 moving to the extreme right position. After installing the workpiece, the gear wheel 1, rotating to the right, moves the shaft 2 to the left, clamping the workpiece and pressing the faceplate 6 to the body 5. To rotate the faceplate 6 together with the workpiece, the protrusion of the cylindrical skid 9 slides off the protrusion 11 of the spring-loaded sleeve 12 and between the last and the cylindrical in sk 9, a gap is formed. Holding the workpiece in a predetermined position during rotation is provided by springs 8, the force of which is less than the spring force. 13. 4 Il.

The invention relates to a machine tool industry and can be used in machine tools containing turning-dividing devices.

The aim of the invention is to reduce the size and expansion of technological capabilities by eliminating the individual power drive of the work clamp mechanism.

FIG. Figure 1 shows a separator bar 3, with the result that a gap "b." Is formed between the end of the gear and the end surface 4 of the housing 5. This gap is selected with the aid of the spring 13. The protrusion 11 of the sleeve 12 is located on the protrusion 10 of the cylindrical shaft 9, and the shaft 2 moves to the extreme right position.

After installing the workpiece must be clamped. Gear tinting at the time of installation of the workpiece; Yu co 1 begins to rotate to the right, and through FIG. 2 is a view A of FIG. one; in fig. 3-th screw connection moves the shaft 2

the dividing device at the time of clamping the workpiece; in fig. 4 is a view B in FIG. 3

The separating device comprises a gear wheel 1, coupled with the device shaft 2 by means of a threaded connection and located between the end surface of the retaining ring 3 that limits its axial movement, which is fixed on the shaft 2 to the left of the gear wheel 1 and the end face 4 of the housing 5.

On the right side, the shaft 2 is connected to the faceplate 6 by means of a movable keyed joint 7, has the possibility of limited axial movement relative to this faceplate and is spring-loaded from the side of the faceplate by a spring 8. On the side opposite to the side of the faceplate 6 on the shaft 2 there is a cylindrical juice 9, on the side surface of which there is a protrusion 10 which is in contact with the protrusion 11 of the spring-loaded sleeve 12. Between the protrusion of the housing 5 and the end of the sleeve 12 there is a cylindrical spring 13. The spring-loaded sleeve 12 has the ability to s

to the left, thereby clamping the workpiece in the chuck and clamping the faceplate 6 to the body 5.

To rotate the faceplate 6 together with the workpiece at a predetermined angle, the protrusion 10 of the cylindrical pole 9 slides off the protrusion 11 of the spring-loaded sleeve 12 and a gap is formed between the last and the cylindrical section 9, which is provided due to the limited axial movement of the spring-loaded sleeve 12 relative to the housing 5 with a finger 14 in the groove 15.

Holding the workpiece in a predetermined position during rotation is provided by springs 8, the forces of which are less than the force of the spring 13, which ensures that the workpiece is pressed out.

Claims (1)

30 Formula of Invention Separating device according to aut. St. No. 1313651, characterized in that, in order to reduce overall dimensions and expand technological capabilities, the shaft carrying the plan 25 limited axial movement relative to the washer, installed with the possibility axially about the body with a finger in the groove 15. The separating device operates as follows. When installing the workpiece in a clamping mechanism such as a collet chuck, shaft 2 occupies the extreme right position. This is achieved by the fact that the gear wheel 1 is moved to the left up to the stop on the end surface of the stop ring 3, as a result of which a gap "b." Is formed between the end face of the gear wheel and the end surface 4 of the body 5. This gap is selected with the aid of the spring 13. The protrusion 11 of the sleeve 12 is located on the protrusion 10 of the cylindrical shaft 9, and the shaft 2 moves to the extreme right position. After installing the workpiece must be clamped. Toothed wheel, thereby clamping the workpiece in the chuck and clamping the faceplate 6 to the body 5. To rotate the faceplate 6 together with the workpiece at a predetermined angle, the protrusion 10 of the cylindrical pole 9 slides off the protrusion 11 of the spring-loaded sleeve 12 and a gap is formed between the last and the cylindrical section 9, which is provided due to the limited axial movement of the spring-loaded sleeve 12 relative to the housing 5 with a finger 14 in the groove 15. Holding the workpiece in a predetermined position during rotation is provided by springs 8, the forces of which are less than the force of the spring 13, which ensures that the workpiece is pressed out. Invention Formula Separating device according to aut. St. No. 1313651, characterized in that, in order to reduce overall dimensions and expand technological capabilities, the shaft carrying the plan 40 The displacement is spring-loaded relative to the latter and is made with a cylindrical strip, the side surface of which from the side opposite to the faceplate is made with a protrusion intended to contact a similar protrusion made on the end surface of the cylindrical body which is spring-loaded relative to the body and axially movable in the axial direction. sleeve, which is located coaxially to the shaft. / / Ii. 213 1 5 ( (pic 2 didb FIG.
