DETAILED DESCRIPTION

[0025] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0026] In the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] See also Figure 1-Figure 5 The embodiment provided by the utility model: a planetary carrier processing and indexing device, comprising: a base 1, a turntable 2, a sleeve 3 and an insert 4; a plurality of limit grooves 11 are opened on the edge of the base 1, and the plurality of limit grooves 11 are evenly spaced along the circumferential direction of the base 1; the turntable 2 is rotatably mounted on the base 1; the sleeve 3 is coaxially sleeved on the base 1, and one end of the sleeve 3 is fixedly connected to the turntable 2; one end of the insert 4 slides through the sleeve 3 along the radial direction of the base 1, and one end of the insert 4 is plugged into the limit groove 11.

[0029] During specific implementation, the planetary carrier can be coaxially fixed to the turntable 2 by a clamp, or the turntable 2 can be fixed by other means, which are not limited here; when the planetary carrier is coaxially fixed to the turntable 2, the planetary carrier can be processed, and when the angle of the planetary carrier needs to be adjusted, the insert block 4 is pulled out from the limit slot 11, and then the sleeve 3 is rotated. The sleeve 3 drives the planetary carrier to rotate through the turntable 2, so that the angle of the planetary carrier can be adjusted; when the angle adjustment of the planetary carrier is completed, the insert block 4 is pushed to slide, so that the plug slides to the nearest limit slot 11, so that the rotation of the turntable 2 and the sleeve 3 can be restricted, and then the rotation of the planetary carrier can be restricted.

[0030] See also Figure 1-Figure 5In other embodiments, a reaction plate and spring 42 are further included. A slot 31 is defined on the sleeve 3, and the reaction plate and spring 42 are positioned within the slot 31. The reaction plate is vertically fixed to the insert 4. One end of the spring 42 abuts the reaction plate, while the other end abuts the inner wall of the slot 31, exerting a thrust on the insert 4 toward the limit slot 11. In practice, the spring 42, via the reaction plate, pushes the insert 4 toward the limit slot 11, thereby limiting the rotation of the planetary carrier on the turntable 2. This eliminates the need to manually push the insert 4, preventing workers from forgetting to do so. The insert can be connected by simply pulling it outward.

[0031] See also Figure 1-Figure 5 In other embodiments, the limiting groove 11 is V-shaped, with the tip of the limiting groove 11 facing the axis of the base 1. A limiting assembly 5 is also included, which can limit the sliding of the insert block 4. In specific implementation, the turntable 2 is directly rotated, and the turntable 2 drives the insert block 4 to rotate. Under the guidance of the inclined surface of the V-shaped limiting groove 11, the insert block 4 slides out of the limiting groove 11 and compresses the spring 42 to accumulate force, thereby adjusting the angle of the planetary carrier. After the angle of the planetary carrier is adjusted, the accumulated force spring 42 pushes the insert block 4 to reinsert into the limiting groove 11 at the corresponding position. Finally, the limiting assembly 5 limits the sliding of the insert block 4, thereby limiting the rotation of the turntable 2 and the sleeve 3, and thus the rotation of the planetary carrier.

[0032] See also Figure 1-Figure 5 In other embodiments, the limiting assembly 5 includes: a rotating shaft 51, an elliptical limiting plate 52 and a knob 53; the rotating shaft 51 is rotatably mounted on the insert block 4, and the elliptical limiting plate 52 and the knob 53 are respectively fixed at both ends of the insert block 4; a through groove 43 is opened on the insert block 4 along the tangential direction of the turntable 2, and the elliptical limiting plate 52 is located in the through groove 43; a card slot 32 is opened on the sleeve 3, and when the insert block 4 is plugged into the limiting groove 11, the elliptical limiting plate 52 can be rotated into the card slot 32 to limit the sliding of the insert block 4.

[0033] When the angle of the planetary carrier needs to be adjusted, the knob 53 is turned, and the knob 53 drives the elliptical limit plate 52 to move out of the slot 32 through the rotating shaft 51, so that the elliptical limit plate 52 is completely moved into the through slot 43; in this way, the turntable 2 can be rotated, and the turntable 2 drives the insert block 4 to rotate. Under the action of the inclined surface guide of the V-shaped limit slot 11, the insert block 4 slides out of the limit slot 11 and compresses the spring 42 to accumulate force, so that the angle of the planetary carrier can be adjusted. After the angle adjustment of the planetary carrier is completed, the accumulated force spring 42 will push the insert block 4 to be reinserted into the limit slot 11 at the corresponding position, and make the through slot 43 and the engaging slot 32 in the same plane, so that the elliptical limit plate 52 can be rotated again, so that the end of the elliptical limit plate 52 in the long axis direction is engaged with the engaging slot 32, thereby limiting the sliding of the insert block 4.

[0034] See also Figure 1-Figure 5 In another embodiment, an annular groove 12 is formed on the edge of the base 1 and is coaxial with the base 1. A limit ring 6 is coaxially fixedly mounted on the end of the sleeve 3 away from the turntable 2, and the inner ring of the limit ring 6 extends into the annular groove 12. In a specific embodiment, the limit ring 6 rotates within the annular groove 12, thereby limiting the axial position of the turntable 2 and the sleeve 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
