Abstract
Description
Technical Field
[0001] This utility model relates to the field of retarder technology, and in particular to a milling fixture for a retarder stator disk assembly. Background Technology

[0032] like Figures 1 to 2As shown, this embodiment provides a milling fixture for a retarder stator disk assembly. The milling fixture includes a support base plate 1, a positioning shaft 2, and multiple sets of support structures 3. The positioning shaft 2 is mounted on the support base plate 1 and can be connected to a bearing seat 6 to position the upper electrode assembly 7 and the lower electrode assembly 8. Multiple sets of support structures 3 are mounted on the support base plate 1 and are spaced circumferentially along the positioning shaft 2. Each support structure 3 can abut against the upper electrode assembly 7 or the lower electrode assembly 8 to support it. The retarder stator disk assembly includes a bearing seat 6, an upper electrode assembly 7, and a lower electrode assembly 8. The bearing seat 6 is installed between the upper electrode assembly 7 and the lower electrode assembly 8. The upper electrode assembly 7 and the lower electrode assembly 8 can be milled by a milling cutter.
[0033] The milling fixture for the retarder stator disk assembly of this utility model is equipped with multiple sets of support structures 3, which are distributed circumferentially along the positioning shaft 2. In this configuration, the multiple sets of support structures 3 can abut at different positions of the upper electrode assembly 7 or the lower electrode assembly 8. When the milling cutter is milling the upper electrode assembly 7 or the lower electrode assembly 8, the downward pressure generated on the upper electrode assembly 7 or the lower electrode assembly 8 provides support, thereby effectively preventing the upper electrode assembly 7 or the lower electrode assembly 8 from being thicker on the outside and thinner on the inside after milling, further improving milling efficiency and milling accuracy. At the same time, the positioning shaft 2 is provided, which can be connected to the bearing seat 6 to position the upper electrode assembly 7 or the lower electrode assembly 8.
[0034] In some embodiments, such as Figure 1 As shown, a set of support structures 3 includes a first support member 31 and a second support member 32. The first support member 31 and the second support member 32 are symmetrically arranged about the central axis of the positioning shaft 2. This arrangement provides support to both sides of the upper electrode assembly 7 or the lower electrode assembly 8, ensuring uniform support and preventing uneven support during milling, which could result in a thicker outer layer and a thinner inner layer.
[0035] In this embodiment, to adjust the position of the first support member 31, the first support member 31 includes a lifting hydraulic cylinder 311 and a support plate 312. The cylinder body of the lifting hydraulic cylinder 311 is mounted on the support base plate 1, and the extension rod of the lifting hydraulic cylinder 311 is connected to the support plate 312. In this way, the lifting hydraulic cylinder 311 can drive the support plate 312 to abut against the upper electrode assembly 7 or the lower electrode assembly 8, thereby achieving the purpose of supporting the upper electrode assembly 7 or the lower electrode assembly 8.
[0036] Specifically, the milling fixture for the retarder stator disk assembly includes a first fastener 4, wherein the support plate 312 is connected to the telescopic rod of the lifting hydraulic cylinder 311 via the first fastener 4, which facilitates installation and disassembly. In this design, the first fastener 4 is a bolt.
[0037] In this embodiment, to facilitate the control of the lifting hydraulic cylinder 311, the milling fixture for the retarder stator assembly also includes a hydraulic manual directional valve 5 mounted on the support base plate 1. The hydraulic manual directional valve 5 is connected to the lifting hydraulic cylinder 311 and can control the locking of the lifting hydraulic cylinder 311.
[0038] Furthermore, the milling fixture for the retarder stator disk assembly includes a second fastener, through which the hydraulic manual directional valve 5 is connected to the support base plate 1. This facilitates installation and disassembly. The second fastener is a bolt.
[0039] Alternatively, in an embodiment not shown in the figure, the support structure 3 includes a lifting cylinder and a support plate 312. The cylinder body of the lifting cylinder is mounted on the support base plate 1, and the extension rod of the lifting cylinder is connected to the support plate 312. The lifting cylinder drives the support plate 312 to abut against the upper electrode assembly 7 or the lower electrode assembly 8. This configuration also achieves the purpose of driving the support plate 312 to support the upper electrode assembly 7 or the lower electrode assembly 8.
[0040] Specifically, the upper electrode plate assembly 7 includes an upper electrode plate body 71 and an upper stator disk 72 connected to each other, and the lower electrode plate assembly 8 includes a lower electrode plate body 81 and a lower stator disk 82 connected to each other. The bearing seat 6 is installed between the upper stator disk 72 and the lower stator disk 82. The upper electrode plate body 71 can be milled by a milling cutter, and the support structure 3 can abut against the lower electrode plate body 81; or, the lower electrode plate body 81 can be milled by a milling cutter, and the support structure 3 can abut against the upper electrode plate body 71. This allows for milling of either the upper electrode plate body 71 or the lower electrode plate body 81.
[0041] Specifically, the retarder stator assembly also includes pole posts 9, which are installed between the upper pole plate body 71 and the lower pole plate body 81. The pole posts 9 serve to conduct magnetism.
[0042] In this embodiment, the milling fixture for the retarder stator disk assembly includes a third fastener, wherein the positioning shaft 2 is connected to the support base plate 1 via the third fastener. This facilitates installation and disassembly.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
