between the axes of the adjacent oasic elements 3 on the axis of the table 2, which coincides with the direction of its movement. The operator 8 is movable in the direction of the surface of the table 2 and has two positions at an angle to each other, one of which has a prism and a pusher, and the other has a prism and two swivel grips with prismatic cams and end tabs, and

 heads among themselves, and at least one of the faces of the prism is located in tray 7. The machine is made in a horizontal version. In one stroke of the auto-operator 8, the product is transferred from the tray 7 along the prism to one base element 3, while the product simultaneously extends the cams through the protrusions that cover it from the table 2 side and feed the prism of the second position of the auto-operator, 5 sludge.

The invention relates to metal cutting and can be used for machining slots on the end of crown nuts.

The aim of the invention is to improve productivity and simplify the design of the machine.

FIG. 1 shows a multi-station machine; Fig 2 is an auto operator for installing and removing parts; in FIG. 3, view A in FIG. 2; Fig. 4 is a diagram of the arrangement of nuts on the dividing table with an indication of the slot formation sequence; Fig. 5 is a schematic of the sequence of moving the nuts along the trough to the drop-off zone in the initial position of the caliper and at the moment of loading.

The machine for milling slots on the ends of the crown nuts contains a tool block 1, a vertical swiveling and dividing table (faceplate) 2 with nut holders (basic elements) 3 moved reciprocatingly and progressively with a skid 4 hydraulic cylinder 5 bunker device 6, receiving tray 7 and auto operator 8,

On mandrels 10 installed in three spindle assemblies 9, cutters 11 are positioned so that their axes are displaced relative to each other by an amount equal to the projection of the distance between the axes of adjacent base elements 3 onto the axis of the table, which coincides with the direction of its movement. On the sled 4 is installed, the hydraulic cylinders 12 clamps with clamps 13.

 The auto operator 8 consists of a body 14 with guides along which the hydraulic cylinder 15 reciprocates the support 16 with a replaceable receiving prism mounted on it

17, a pusher 18 and a device for removing and unloading nuts, made in the form of two twisted grips 21 connected by a rod 19 with a spring 20 with prismatic cams 22 fixed to their ends with end lugs 23 and a horizontally located prism 24 for moving the nuts into the zone of fallout. The installation and removal of the nuts on the dividing table 2 takes place at positions 25 and 26, the processing of the slots is at positions 27 to 29. All machine components are located on the bed 30, At least one face of the prism 17 is located inside the tray 7,

The machine works as follows. In the initial position of the caliper 16 of the auto-operation 8, the nut from the receiver of the bunker device 6 enters the receiving prism 17, orienting it through the faces and end of the pusher.

18, The installation of the nut in the nut holder 3 is preceded by the return of the slide 4 with the table 2 to the initial position, determined by the coincidence of the axis of the hole in the nut located in the receiving prism 17, with the axis of the nut holder 3,

and the positioning of the table 2, associated with the transfer of the previously installed nut to the machining position 27 and the machined nut to the unloading position 26.

End of table positioning. coincides with the beginning of the movement of the caliper 16, the pusher 18 of which, holding the side surface of the nut, located in the receiving tray 7 of the bunker device 6, pulls the nut, 5 in the receiving prism 17, onto the axis of the encoder 3 from the receiving prism.

At the same time, at the end of the slide caliper 16, the processed nut, which is in the unloading position 26, with its faces O, touching the end projections 23 of the prismatic cams 22, spreads the grippers 21, pushing the end of the cam prisms 22 into the prism 24. - 5 times the nuts in it with a pitch equal to their height.

After the protrusions 23 of the cams 22 have passed, the nut faces under the action of the springs 20, the claws 21 come down and the end protrusions 23 of the cams 22 are located behind the end of the nut, removing it from the nut of the nut holder 3 during the reverse course of the caliper 16. Releasing the caliper 16 to load the subsequent nut matches the start Trying the sled 4 and milling the slots on the nuts transferred by the dividing table in position 27 - 29, presumptively pressed with tacks 13.

Claims (1)

After the processing of the sled with table 2 is completed, the initial position is rapidly returned and the cycle is repeated. Claims. Multi-position machine for cutting holes in the crown nuts. containing a frame, a turning-dividing table with base elements evenly spaced around its circumference under the nuts to be machined, the axes of which are parallel to the axis of the table mounted for movement in the direction perpendicular to its axis, a tool block made in the form of three spindle assemblies whose axes are perpendicular are the direction of movement of the table, the loading and unloading device, which is characterized by the fact that, in order to increase the productivity of the machine and to simplify the design, the spindles The tal block is set offset from each other by an amount equal to the projection of the distance between the axes of the adjacent basic elements of the table on its axis, which coincides with the direction of its movement, while the loading device is made in the form of a tray fixed on the frame, prism and pusher, and unloading device - in the form; the second prism and two hinged grippers with prismatic cams attached to them and end projections located between the prism and the table, both prisms and the pusher are rigidly connected to each other and installed with the possibility of reciprocating movement in the direction of the table surface, and at least One of the faces of the prism boot device is located inside the tray. fj w 29 VU2.3 27 9uz. 9ig.5
