Abstract

The present invention relates to a socket alignment device for a bar loading magazine for guiding a bar of material to an automatic lathe, wherein a z-axis (z) is defined by the longitudinal axis of a bar of material (2) guided in the bar loading magazine, and wherein a first socket (1), into which the bar of material (2) is to be introduced for processing thereof in the automatic lathe along the z-axis, is arranged in the bar loading magazine, wherein the first socket (1) is mounted so as to be rotatable either coaxially about the z-axis (z) or about a rotational axis (ζ′) parallel to the z-axis (z) and wherein at least one drive means (6) is included, which can be coupled at least to the first socket (1), specifically to the rotary drive of the first socket (1) about the z-axis (z) in such a manner that the first socket (1) and the cross-sectional profile of the bar of material (2) can be aligned flush with one another for introduction of the bar of material (2).

Dependent claims

A bushing alignment device of a bar loading magazine for guiding material bars on an automatic lathe,

wherein a z-axis (z) is defined by the longitudinal axis of a material bar guided in the bar loading magazine, and
wherein a plurality of first bushings, which can be moved along the z-axis (z) and into which the material bar is to be inserted along the z-axis (z) for processing in the automatic lathe, are arranged in the bar loading magazine,
wherein a first rotational axis, which is arranged either coaxially or parallel to the z-axis (z) and about which the first bushings are rotatably mounted, extends through the first bushings,
wherein alignment between the first bushings and a cross-sectional profile of the material for inserting the material bar at a predetermined rotational position is achieved by one or more of:
(i) one or more friction wheels as drive means, which for force transmission can be selectively coupled to the first bushings or decoupled therefrom by a pivoting device, to which the drive means are attached and which can be pivoted toward the first bushings for coupling thereto, and wherein the first bushings can be coupled to the drive means in a friction-fit manner and are driven by a linear motor, by a rotatorily acting motor and/or by an actuator motor, for rotatorily driving the first bushings about the first rotational axis to the predetermined rotational position, and
(ii) one or more holding units, which are adapted to selectively retain the first bushings in the predetermined rotational position.

A bushing alignment device of a bar loading magazine for guiding material bars on an automatic lathe,

wherein a z-axis (z) is defined by the longitudinal axis of a material bar that is guided in the bar loading device, and
wherein a first bushing, into which the material bar is to be inserted along the z-axis (z) for the processing thereof in the automatic lathe, is arranged in the bar loading magazine,
wherein a first rotational axis, which is arranged either coaxially or parallel to the z-axis (z) and about which the first bushing is rotatably mounted, extends through the first bushing, and
wherein at least one drive means is included, which is coupled to the first bushing, for rotatorily driving the first bushing about the first rotational axis in such a way that the first bushing and a cross-sectional profile of the material bar can be aligned flush with each other for inserting the material bar,
wherein a second bushing is arranged movably along the z-axis (z) in the bar loading magazine, and wherein a second rotational axis, which is arranged either coaxially or parallel to the z-axis (z) and about which the second bushing is rotatably mounted, extends through the second bushing, and
wherein the material bar is to be inserted into the second bushing along the z-axis (z), wherein the first and second bushings have entrainment means designed in complementary manner to each other, in the form of friction surfaces and/or magnetically acting surfaces and/or an engaging means and a receiving portion, so that the first and second bushings are coupled to each other with friction fit and/or positive fit in such a way that a rotation of the first bushing causes the second bushing to be entrained.
