[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Please refer to Figure 1-Figure 3 The present invention discloses a positioning and clamping tool for a planetary carrier. The planetary carrier 100 includes a main body having a bottom plate 110 and a top plate 120. The bottom plate 110 has a first surface facing the top plate 120 and a second surface facing away from the top plate 120. A center plate 130 is provided on the second surface. The end of the center plate 130 away from the top plate 120 has a first positioning surface. The positioning and clamping tool 200 includes:

[0030] A positioning plate 230 having a second positioning surface, wherein the second positioning surface can be fitted with the first positioning surface;

[0031] The first positioning assembly 210 includes a plurality of first positioning units arranged along the circumference of the center disk 130. The first positioning units include positioning rods 221 that can move toward or away from the center of the center disk 130. The ends of the positioning rods 221 are provided with positioning portions that can abut against or separate from the outer peripheral wall of the center disk 130.

[0032] The second positioning assembly 220 includes a plurality of second positioning units arranged circumferentially along the center disk 130 . The second positioning unit includes a movably arranged pressing rod 211 . The pressing rod 211 is provided with a pressing portion that can abut against or separate from the first surface.

[0033] Specifically, the first positioning assembly 210 in the present application includes a plurality of first positioning units arranged circumferentially along the center disk 130, and the positioning rods 221 in the plurality of first positioning units abut against the outer peripheral wall of the center disk 130 inward in the horizontal direction, thereby positioning the center disk 130 to center the entire planetary carrier 100 and avoid radial runout during processing.

[0034] The second positioning assembly 220 in the present application includes a plurality of second positioning units arranged circumferentially along the center disk 130. The clamping rods 211 in the plurality of second positioning units press downward against the upper surface of the top plate 120, so that the first positioning surface on the center disk 130 is fitted with the second positioning surface, thereby making the entire planetary carrier 100 fit on the positioning disk 230 along a horizontal angle (or other preset angles), avoiding end jump during processing.

[0035] Furthermore, the first positioning unit further includes a mounting seat 222 , and the positioning rod 221 is threadedly connected to the mounting seat 222 .

[0036] Furthermore, a threaded hole is formed on the mounting seat 222 , and an external thread is formed on the positioning rod 221 , and the external thread is engaged with the threaded hole.

[0037] Specifically, by rotating the positioning rod 221, the positioning rod 221 moves along the axial direction of the threaded hole (i.e., the horizontal direction) until the positioning parts on all the positioning rods 221 abut against the center disk 130 at the same time; by controlling all the positioning rods 221 to move the same distance and fine-tuning the center disk 130 to a position where it can abut against all the positioning parts, the center positioning of the planetary carrier 100 is achieved.

[0038] Furthermore, the pressing rod 211 is further provided with a hinge portion, and a locking portion is further provided between the hinge portion and the pressing portion;

[0039] The second positioning unit further includes:

[0040] A fixing seat 212, which is fixed to the positioning plate 230, and the upper end of the fixing seat 212 is hinged to the hinge portion;

[0041] The locking rod 213 can be in contact with or separated from the locking portion to lock or release the rotation of the pressing rod 211 relative to the fixing seat 212 .

[0042] Furthermore, a through hole is provided on the locking portion;

[0043] One end of the locking rod 213 is connected to the positioning plate 230 , and the other end passes through the through hole and can abut against the upper surface of the pressing rod 211 .

[0044] Furthermore, a limiting head is provided at one end of the locking rod 213, and the limiting head is configured to be unable to pass through the through hole and can abut against the upper surface of the clamping rod 211, and the other end of the locking rod 213 passes through the through hole and is threadedly connected to the positioning plate 230.

[0045] Furthermore, one end of the locking rod 213 is fixed to the positioning plate 230 , and the other end passes through the through hole and is threadedly connected with a nut. The nut is configured to be unable to pass through the through hole and can abut against the upper surface of the pressing rod 211 .

[0046] Specifically, regarding the setting of the locking rod 213, a threaded section can be set at the lower end of the locking rod 213, so that the threaded section is threadedly connected to the positioning plate 230. By rotating the locking rod 213, the limit head at the upper end of the locking rod 213 is pressed against the upper surface of the clamping rod 211, so that the clamping rod 211 applies a downward force to the base plate 110, thereby making the first positioning surface and the second positioning surface fit tightly, ensuring that the planetary carrier 100 is level and avoiding end jumping.

[0047] A threaded section can also be provided at the upper end of the locking rod 213, and the lower end of the locking rod 213 is fixedly connected to the positioning plate 230. The threaded section passes through the through hole and is locked by a nut. The nut rests on the upper surface of the clamping rod 211, so that the clamping rod 211 applies a downward force to the base plate 110, thereby making the first positioning surface and the second positioning surface fit tightly, ensuring that the planetary carrier 100 is level and avoiding end jumping.

[0048] Furthermore, a plurality of threaded holes are formed on the positioning plate 230 , and the center plate 130 is connected to the positioning plate 230 by bolts.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0051] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0052] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
