Abstract

The invention relates to the processing of materials by cutting, in particular to multi-position rotary devices for machine tools. The invention makes it possible to increase productivity by reducing the orientation time of complex shaped parts. In the turntable 1, placed on the bottom plate with guides 5, an annular recess is made. in which one of the two arcuate guide protrusions 7 is located. Above the projections 7 a cassette 8 with details is placed. Each receiving cell 2 is equipped with a replaceable element - a tooth 9. A spring-loaded retainer is installed in the upper plate 12, and two stops are fixed in the lower plate. The clamping device with the clips receives movement from the power motor - the hydraulic motor 18. The tooth 9 interacts with a spring-loaded pawl placed on the rotary actuator. When parts are loaded into the cassette 8, the lower part falls on the protrusion 7 into the receiving cell 2 of the turntable 1, orienting it with the tooth 9. When the table 1 rotates, the part moves along the projections 7, passes over the stops and enters the guides 5. Spring-loaded latch moves down and, falling into the center hole of the part, precisely orients it relative to the stops and presses it to them. 1 hp f-ly, 9 ill. i (L

The invention relates to the processing of materials by cutting, in particular to multi-position rotary devices for machine tools.

The aim of the invention is to increase productivity by reducing the time of orientation of parts.

The multi-position rotary device comprises a rotary table I, which is a disk with receiving cells 2, each of which partially reverses the contour of the part. The turntable I is placed on a stationary case, the bottom plate 3 of which is made integral with the column 4, on the circular guides 5 of the lower plate 3 is placed the turntable I with an annular recess b on the side of the bottom plate 3 equipped with two arc-shaped guides 7 over which placed the cassette 8 with the details. The length of the protrusions 7 is equal to the distance from the loading position to the working position. One of the protrusions 7 is located in the annular recess 6 of the rotary table 1. The pre-orientation device of the part contains an interchangeable element 9 made in the form of a tooth commensurate with the teeth of the workpiece and mounted in the receiving cell 10 of the rotary table 1. Each cell 2 is supplied with interchangeable element 9, made in the shape of the grooves of the teeth of the product. The device of precise orientation of the part includes a spring-loaded clamp 11 placed in the top plate 12 and two stops 13, made in the form of fingers mounted on the bottom plate 3 and located at a height below the top, line of projections 7, and the axis of the spring-loaded clamp 11 is offset relative to the central hole of the part in the direction of the stops 13. The turntable 1 is provided with bushings 14 with openings for the entrance of the stopper 5 when the table 1 is rotated by a step equal to the distance between two neighboring cells 2.

The T-shaped shaft of the spring-loaded latch 11 is located in the body of the rocking chair 16. In the same body of the rocking chair 16, axes 17 are mounted on the axles, receiving movement in the same way as the spring-loaded latch 11, from the hydraulic motor 18 through the lever 19 and the slide bar 20 A reflector 2i is attached to the upper plate 12 at the working position, which prevents the part from lifting when the spring-loaded clamp 11 moves upwards.

The rotation motor 23 interacts with the interchangeable element 9. In the zone of removal of parts in the bottom plate 3 there is a rectangular recess 24, under which the tray 25 is located.

The device works as follows.

A stack of parts is stacked in the loading cassette 8. In this case, the lower part falls on the protrusion 7 into the receiving cell 2 of the turntable 1, orienting itself with a pre-replaceable element 9. When turning on the turn hydraulic motor 23, the turntable is rotated 1 step. In doing so, the stopper 15 enters the opening of the hub 14 of the table 1, and the pawl 22 returns to its original position.

Then, when the turning hydraulic motor 23 is turned on for the second time, the part is moved from the intermediate position to the working one, i.e. the part moves along the protrusions 7, passes over the stops 13 and enters the direction 5. With the hydraulic motor 18, the spring-loaded latch G1 moves downwards and, falling into the central hole of the part, precisely orients it relative to the stops 13 and presses it to them. Upon further movement of the hydraulic motor rod 18, the spring-loaded latch 11 stops moving, the clamps 17 continue to move until the part is clamped, the spring of the spring-loaded latch 11 is compressed, and the stopper 15 simultaneously releases the rotary table I. 17 and spring clamp II release the part. The cycle then repeats and, as cell 2 with part passes over cut-out 24 in the bottom plate 3, the part falls onto the inclined chute 25 into the removal zone.
