Technical Field

[0001] The utility model belongs to the field of workpiece assembly devices, in particular to an assembly fixture. Background Art

[0002] Figure 1 The product shown is a reducer output planetary carrier, which includes a cylindrical platform and a triangular disk arranged on the cylindrical platform. Each vertex of the triangular disk is provided with a through hole, and a planetary gear shaft needs to be installed in each through hole. Figure 2 For the structure after the planetary gear shaft is installed.

[0003] In the prior art, it is difficult to install three planetary gear shafts into the output planetary carrier at one time, and the installation process is time-consuming and labor-intensive. Therefore, it is of great significance to provide a fixture that can install three planetary gear shafts into the output planetary carrier at one time. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies and defects mentioned in the above background technology and provide a fixture for assembling a planetary gear shaft and a reducer output planetary carrier, which can simultaneously install three planetary gear shafts into the output planetary carrier at one time.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is:

[0006] A fixture for assembling a planetary gear shaft and a reducer output planetary carrier, the reducer output planetary carrier comprising a cylindrical table and a triangular disk arranged on the cylindrical table, each vertex of the triangular disk being provided with a through hole for mounting a planetary gear shaft, the fixture comprising from bottom to top a lower die base plate, a lower die plate pad, a lower die plate, an upper die plate and an upper die base plate, an upper die insert being provided in the upper die plate, a lower die insert being provided in the lower die plate pad, three mounting seats for vertical pre-installation of planetary gear shafts being provided in the lower die plate, three mounting holes being provided on the mounting seat, the mounting seat being provided on the lower die insert, a groove being provided on the bottom surface of the upper die insert for accommodating the cylindrical table, a gap being provided between the upper die insert and the mounting seat for accommodating the triangular disk, the through holes in the triangular disk corresponding one to one to the positions of the mounting holes.

[0007] In the above-mentioned fixture for assembling the planetary gear shaft and the output planetary carrier of the reducer, preferably, the cavity opened in the lower template for accommodating the mounting seat is larger than the mounting seat, and the mounting seat is movably arranged in the lower template.

[0008] In the above-mentioned fixture for assembling the planetary gear shaft and the output planetary carrier of the reducer, preferably, the mounting seat sleeve is arranged on a positioning pin and can rotate along the positioning pin, and the lower end of the positioning pin is arranged in the lower template pad.

[0009] In the above-mentioned fixture for assembling the planetary gear shaft and the output planetary carrier of the reducer, preferably, a fixing washer for limiting the vertical position of the mounting seat is further provided between the upper template and the lower template, and the fixing washer is pressed onto the mounting seat.

[0010] In the above-mentioned fixture for assembling the planetary gear shaft and the output planetary carrier of the reducer, preferably, guide columns are provided between the lower template pad, the lower template, and the upper template.

[0011] The fixture for assembling the planetary gear shaft and the output planetary frame of the reducer of the utility model has three mounting seats for vertical pre-installation of the planetary gear shaft in the lower template, and the mounting seats are provided with three mounting holes, so that the planetary gear shaft can be pre-installed in the mounting holes. When the planetary gear shaft needs to be installed in the output planetary frame of the reducer, the planetary gear shaft is first installed in the mounting hole, and then the output planetary frame of the reducer is placed in the fixture, so that the three through holes of the output planetary frame of the reducer are aligned with the planetary gear shaft, and the upper template is pressed down to press the planetary gear shaft into the three through holes of the output planetary frame of the reducer, and the installation is completed. The three planetary gear shafts can be pressed into the three through holes of the output planetary frame of the reducer at one time, which saves time and effort.

[0012] In addition, due to the differences in the processed output planetary frames of the reducer, the positions of the three through holes will also be different. If the mounting seat is set to be fixed, when the planetary gear shaft is pressed into the three through holes of the output planetary frame of the reducer, the planetary gear shaft may be subjected to shear stress, resulting in the product being difficult to remove. The fixture for assembling the planetary gear shaft and the output planetary frame of the utility model designs the mounting seat as a movable part that can swing slightly, so that the planetary gear shaft can be placed vertically on the bottom surface and can be slightly aligned according to the product hole position during shaping. After pressing the shaft, the shear stress can be released to facilitate product removal.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] The fixture for assembling the planetary gear shaft and the output planetary frame of the reducer of the utility model has a simple structure and is easy to use. Three planetary gear shafts can be pressed into the three through holes of the output planetary frame of the reducer at one time, which saves time and labor and can greatly improve the assembly efficiency of the planetary gear shaft and the output planetary frame of the reducer.
