Definitions

  • the invention relates to a pivoting unit with a pivotable from a first rotational end position in a second rotational position pivoting part and with a housing provided in a drive for the pivoting part.
  • pivoting units are previously known from the prior art in many ways. They are used in particular for positioning components or as hinges of handling devices.
  • gripping or holding devices can be arranged on the pivoting part with which components can be displaced from a first position, from the first rotational end position of the pivoting part, into a second position, into the second rotational end position of the pivoting part. In the rotary end positions, the components can then either be edited or implemented.
  • the present invention is therefore based on the object to provide a pivot unit that solves this problem.
  • a pivoting unit with the features of claim 1 is proposed.
  • the pivoting unit is thus distinguished by the fact that a holding element displaceable transversely to the direction of rotation of the pivoting part is provided such that upon reaching a rotational end position, the retaining element is displaced from a release position into a holding position and thereby the pivoting part is held in the rotational position.
  • the holding element may be formed in particular pin or bolt-like and is preferably housed in the housing.
  • the holding element is preferably arranged to be displaceable parallel to the axis of rotation of the pivoting part.
  • the holding element may preferably cooperate with the pivoting part in the rotational position non-positively or positively.
  • the holding element is arranged so that it urges the pivoting part in the rotational end position.
  • the urging of the pivoting part in the rotary end position has the advantage that the pivoting part can take up play and repeat accuracy.
  • the high-precision machining of the components it is necessary that the rotational end positions are taken accurately and without play.
  • the swiveling part can have, in particular in the central region, a central passage through which, for example, cables or hoses can be guided, in which, for example, sensors, in particular cameras, can be arranged or through which smaller components can also be passed.
  • the holding element is arranged so that it is arranged resiliently biased towards the pivoting part, ie in the transverse direction with respect to the direction of rotation and in particular parallel to the axis of rotation of the pivoting part in the holding position and / or away from the pivoting part in the release position.
  • This has the advantage that the holding element is arranged in the holding position and / or in the release position urged.
  • the holding element as such preferably has a contact portion which cooperates in the rotational end position with a pivot-part-side mating contact portion.
  • the contact portion as such may be formed as a cylinder portion and the mating contact portion as a cylinder recess.
  • the cylinder portion and the cylinder recess are preferably complementary to each other and may preferably provide a circular cross-section.
  • the contact portion and / or the mating contact portion are formed as inclined or cone sections.
  • the contact portion is formed complementary to the mating contact portion, it can be achieved that when displacing the retaining element from the release position to the holding position due to the inclined or cone section, the pivoting member is urged into the respective rotational end position. This is possible because, as a result of the contact section formed as an inclined or conical section and complementary formed counter contact section during axial movement of the holding element, a force component in the direction of rotation towards the rotation end position can be generated.
  • the pivot member has stopper portions which cooperate on reaching the respective rotational end position with housing-side counterstops.
  • the contact portion and the mating contact portion are formed as inclined or conical sections, yet the pivot member can be hit against the counter sections without play.
  • the position of the abutment sections and / or opposing sections for adjusting the respective rotational end positions is adjustable.
  • the setting of the rotational end positions can also be effected by a displacement of the retaining element transversely to its longitudinal axis. Overall, however, it should be noted that the adjustment can only take place in the region in which the retaining element can urge the pivoting part in the respective rotational end position.
  • the holding element delimits at least one pressure chamber in such a way that it is displaced into the holding position or into the release position when pressure is applied or when the pressure chamber is depressurized. It can also be provided that the holding element delimits two pressure chambers, wherein a pressure chamber upon pressurization urges the holding element in the release position and the holding element is displaced into the holding position when pressure is applied to the other pressure chamber.
  • the pressurization of the pressure chamber bounded by the retaining element can be effected in such a way that the retaining element is then displaced into the release position when the drive is actuated for pivoting the pivoting part.
  • the drive as such can also be compressed air actuated.
  • a piston drive can be used, which limits réelle Kunststoffbeetzschlagbare pressure chambers.
  • the pivoting part comprises a pinion, via which the pivoting part can be driven by the drive, wherein the drive can in particular have a toothed rack cooperating with the pinion or a toothed wheel cooperating with the pinion. It is also conceivable that a corresponding gear is provided between the drive and the pinion.
  • the housing provides a receiving space for the holding element, wherein the receiving space on the side facing away from the pivoting part with an openable lid is closed.
  • the retaining element is accessible so that it can be serviced or replaced.
  • FIG. 1 shows a perspective view of a pivoting unit according to the invention
  • FIG. 2 shows the bottom view of the swiveling unit according to FIG. 1,
  • FIG. 3 shows the top view of the pivoting unit according to FIG. 1,
  • FIG. 4 shows a section through the pivoting unit along the line IV in FIG. 3,
  • FIG. 6 shows a section through the pivoting unit along the line VI in FIG. 3,
  • FIG. 1 shows a pivoting unit 10 with a pivotable between a first rotational position and a second rotational position pivot member 12 and a housing 14 is shown.
  • a drive 16 is housed, with which the pivoting part 12 can be pivoted.
  • holes 18 and recesses 20 are provided, on which clamping devices, support member or other means for clamping, carrying or handling of components can be arranged.
  • the pivoting unit 10 has a central passageway 22, which can be seen clearly in particular in FIGS. 4 and 6. For example, connecting cables or hoses can be passed through the center passage, sensor systems can be mounted in them, or components can be guided through them.
  • pivot bearings 24 in the form of ball bearings are arranged between the pivoting part 12 and the housing 14. As a result, the pivoting part 12 is rotatably mounted on the housing 14.
  • a pinion 28 is provided on the section of the pivoting part 12 located within the housing 14. As is clear from the section according to FIG. 7, this pinion 28 cooperates with the drive 16.
  • the drive 16 in this case comprises a double-sided acted upon drive piston 30, which comprises on the pinion 28 side facing a cooperating with the pinion 28 rack portion 32.
  • the drive piston 30 bounded in the longitudinal direction of two pressure chambers 34 which are mutually acted upon by compressed air access 36 with compressed air, thereby the piston 30 can be moved in the axial direction.
  • the rack portion 32, the pinion 28 and thus the pivot member 12 is pivoted about their clearly visible in Figure 4 center longitudinal axis 38.
  • the pivoting part 12 stop portions 39, 40, which are clearly visible in particular in Figure 8.
  • the stopper portions 39, 40 are provided on a circular segment portion 42 of the pivot member 12, which includes a 90 ° angle.
  • the contact sections 39, 40 cooperate in the rotary end position with housing-side counterstops 44, 46.
  • the counterstops 44, 46 are formed by screwed into the housing 14 screws 48, which is also clear from Figure 8.
  • the respective rotational end position of the pivoting part 12 can be changed.
  • a retaining element 50 which is displaceable transversely to the direction of rotation of the pivoting part 12 is provided.
  • the longitudinal axis 52 of the retaining element 50 extends parallel to the axis of rotation 38 of the pivoting part 12.
  • the retaining element 50 is accommodated in the housing 14.
  • the housing 14 provides for this purpose a holding element holder 54, which is closed on its underside with a lid 56.
  • the retaining element 50 provides a contact section 58, which is provided on the side facing the pivoting part 12 and which is cone-shaped.
  • the holding element 50 can be displaced from a retracted release position into an extended holding position shown in FIGS. 5 and 6.
  • the retaining element-side contact portion 58 engages in a swivel-part-side mating contact portion 60.
  • the contact portion 58 is formed conical or truncated cone.
  • the mating contact portion 60 is formed as a recess having a contour complementary to the contact portion.
  • the pivoting part 12 has two mating contact sections 60 designed as conical recesses, namely one in each of the two end positions. Upon reaching the respective end position of the contact portion 58 of the holding member 50 can dip into the respective mating contact portion 60.
  • the contact portion 58 and the complementary mating contact portion 60 can be achieved that, when the holding member 50 is moved to the holding position, as Figure 5 shows, the contact portion 58 acts against the mating contact portion 60 and at the same time the pivot member 12 in Direction of rotation is urged into the respective rotational end position. Due to the urging of the pivot member 12 in the rotational end position can be achieved that the pivot member 12 assumes the rotational end position backlash and repeat accuracy. Due to the inclined contact surfaces of the contact portion 58 and the mating contact portion 60, a force component in the direction of rotation is provided which urges the pivot member 12 in the respective rotational end position.
  • the holding element 50 is advantageously arranged biased towards the pivoting part 12 by means of a helical spring 62.
  • the holding element 50 also delimits a pressure chamber 64 which can be acted upon with compressed air.
  • the pressure chamber 64 is acted upon, the holding element 50 is moved against the spring force of the helical spring 62 into the release position.
  • the retaining element 50 moves into the holding position.
  • the retaining element 50 also defines a second pressure chamber 66, which can be actively acted upon by compressed air via a compressed air connection, so that the retaining element 50 can also be moved into the retaining position by pressurizing this pressure chamber 66.
  • the holding element 50 is moved from the holding position into the release position by pressurizing the pressure chamber 64.
  • the drive 16 is actuated by pressurizing the corresponding pressure chamber 34 and the resulting movement of the piston 30. Due to the actuation of the drive 16, the pivot member 12 is pivoted about the pinion 28 in the other rotational end position.
  • the contact portion 58 dips into the mating contact portion 60. Due to the conical design of contact portion 58 and mating contact portion 60, the pivoting member is then urged into the corresponding rotational end position.
  • the holding element 50 can thus be achieved that the pivot member 12 is held securely in the respective rotational end position. It is still possible to change the respective rotational end position, at least in a certain range, by adjusting the screws 48.
