Description

Tool for rapidly installing and positioning planetary shaft

Technical Field

The utility model relates to the field of motor assembly and installation, in particular to a tool for quickly installing and positioning a planetary shaft.

Background

The planet carrier is of a split structure, namely the planet shaft and the planet carrier are separated and are connected together in an interference fit and pin shaft limiting mode, the structure is adopted to ensure that the pin holes on the planet shaft are strictly aligned with the pin holes on the planet carrier after the planet shaft is inserted into the corresponding holes of the planet carrier in the installation process, and corresponding installation tools are required to be designed to facilitate strict alignment of the two pin holes and penetration of a subsequent pin shaft.

Because 3 and 4 planetary shafts can be arranged on the planetary carrier, the existing tool can only be used for arranging one planetary shaft at a time, the operation is complicated, the efficiency is low, and the reliability is poor in the installation process; the prior art scheme is provided with an independent guiding device, so that the defects of complex use and operation, higher tooling design cost and the like are overcome.

Disclosure of Invention

In order to solve the technical problems or one of the technical problems in the prior art, the utility model discloses a tool for quickly installing and positioning a planetary shaft, which comprises a contact plate, wherein an external stress end is arranged at the top of the contact plate, a limit guide groove matched with a boss at one end of the planetary shaft is arranged on the bottom surface of the contact plate, the groove wall of the limit guide groove is a circular guide surface, and a limit surface matched with the limit surface of the planetary shaft is arranged on the guide surface.

Further, the external stress end is cylindrical or square.

Further, the side surface of the bottom of the external stress end is fixedly connected with a stress guide rib, and the bottom of the stress guide rib is fixedly connected with the contact plate.

Further, the contact plate is of a triangular structure.

Further, the number of the limit guide grooves is not less than 2.

Further, the stress guide ribs are multiple.

Compared with the prior art, the utility model has the advantages that a plurality of limit guide structures are arranged at one end of the contact plate, and the limit guide structures are intersected with one another, so that the operation and the use are convenient, and the efficiency is high; the limiting guide groove is provided with a limiting surface which can be used for aligning the two pin shaft holes, and compared with other structures, the limiting guide groove has the advantages of high installation precision, good reliability and convenient use; the limiting guide grooves are mutually restrained, a guide device is not required to be additionally arranged, the operation flow is simplified, and the tooling design cost is reduced.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are included in the protection scope of the present utility model.

The technical scheme adopted by the utility model shown in fig. 1-4 is as follows: the utility model provides a frock for installing fast and location planet axle, includes contact plate 1, the top of contact plate 1 is equipped with outside atress end 2, the bottom surface of contact plate 1 be equipped with planet axle one end boss department matched with spacing guide way 4, the cell wall of spacing guide way 4 is circular guide face 6 for with the epaxial boss of planet guide smoothly in leading-in spacing guide structure, be equipped with on the guide face 6 with the spacing face 5 of planet axle spacing face cooperation, be used for the alignment of pinhole.

Preferably, the external stress end 2 is cylindrical or square, and is mainly used for bearing external force.

Preferably, the side surface of the bottom of the external stress end 2 is fixedly connected with a stress guide rib 3, and the bottom of the stress guide rib 3 is fixedly connected with the contact plate 1, and is mainly used for connecting the external stress end with the contact plate and transmitting corresponding force.

Preferably, the contact plate 1 has a triangular structure.

Preferably, the number of the limiting guide grooves 4 is 3, and the number of the limiting guide grooves can be increased or decreased according to actual requirements.

Preferably, the number of the stress guiding ribs 3 is plural.

According to the practical method, the tool is placed on the upper portion of the planetary shaft, the planetary shaft is rotated, the limiting surface on the planetary shaft corresponds to the tool limiting surface designed by the practical method, after the planetary shafts are rotated to the corresponding positions, the boss on the planetary shaft can enter the limiting guide groove, external force can be applied after entering according to the direction indicated by the arrow in the figure, and the upper and lower directions can be judged to reach the corresponding positions through experience (after the gears and the gaskets are installed in place, the positions of the pin holes in the upper and lower directions can be fixed, and different sounds are transmitted).
