Description

Technical Field

[0001] The utility model relates to the technical field of remanufacturing generators, in particular to a generator stator inner diameter shaping device. Background Art

[0002] The stator of a remanufactured generator is the stationary part of the generator. The stator of the generator is mainly composed of two parts: the stator core and the stator winding. Among them, the stator core is formed by sand casting (spiral lamination). When the remanufactured generator is disassembled and transported, it is necessary to dip the stator core into insulating paint and process it after disassembly. In this series of processes, it is usually easy to collide with the stator core, causing the thinner side of the inner hole side wall on the inner wall of the stator core to deform. Therefore, before the inner and outer diameters of the stator core are polished and re-sprayed, the stator core needs to be internally shaped to ensure the precision of the stator core installation.

[0003] At present, when shaping the generator stator, the stator core is usually fixed and limited by an existing clamp, and then a cylindrical rod is used in combination with hydraulic equipment to push directly or the inner wall of the stator core is manually struck to achieve the shaping of the stator core. However, such a generator stator shaping method has low accuracy and it is difficult to ensure that the stator core is accurately installed in the subsequent assembly process. In addition, during the shaping of the stator core, due to the large vibration generated by the direct pushing of the cylindrical rod and the shaping of the stator core, the position of the stator core spiral lamination is offset, which in turn causes the stator core shaping efficiency to be too low and the remanufacturing reuse rate to be low. Utility Model Content

To achieve the above purpose, the utility model adopts the following technical solutions:

The outer surface of the cylinder is a cylindrical surface with a diameter smaller than the inner diameter of the generator stator, and the inner surface of the cylinder is a tapered groove that decreases from the top to the bottom, and the tapered groove matches the outer surface of the upper tooling mold.

[0006] The lower tooling mold is installed in the inner wall of the generator stator, and the upper tooling mold is installed in the lower tooling mold. The servo mechanism is provided with a pressure head, and the servo mechanism controls the pressure head to press down to the surface of the upper tooling mold, so that the upper tooling mold moves downward to open the lower tooling mold assembly block.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, the utility model discloses a remanufactured generator stator inner diameter shaping device, comprising: a servo mechanism 1, a tooling upper mold 3 and a tooling lower mold 5. The outer surface of the tooling upper mold 3 is a conical columnar body that decreases from the top to the bottom, such as Fig.10 shown.

[0031] The tooling lower mold 5 comprises: a plurality of tooling lower mold blocks 11 and an elastic element 12. The plurality of tooling lower mold blocks 11 are spliced ​​to form a cylinder. The cylinder has at least two tooling lower mold grooves 13 formed in the circumference. The elastic element 12 is installed in the tooling lower mold groove 13 to splice the plurality of tooling lower mold blocks 11. Figure 6and Figure 8 shown.

[0032] And, if Figure 8 As shown, the outer surface of the cylinder is a cylindrical surface with a diameter smaller than the inner diameter of the generator stator, and the inner surface of the cylinder is a tapered groove that decreases from the top to the bottom, and the tapered groove matches the outer surface of the upper mold 3 of the tooling.

[0033] like Figure 2 and Figure 3 As shown, the tooling lower mold 5 is installed in the inner wall of the generator stator, and the tooling upper mold 3 is installed in the tooling lower mold 5. The servo mechanism 1 is provided with a pressing head 2, and the servo mechanism 1 controls the pressing head 2 to press down on the surface of the tooling upper mold 3, so that the tooling upper mold 3 moves downward to open the tooling lower mold assembly 11. The outer surface of the tapered column is inclined at an angle of 20 to 60 degrees to the horizontal plane.

[0034] The elastic element 12 is usually an elastic O-ring, and in other embodiments, the elastic element 12 may also be a spring, a rubber band, an elastic band, etc. In this embodiment, the tooling lower mold 5 is composed of three tooling lower mold blocks 11 and an elastic O-ring, and each tooling lower mold block 11 is provided with at least two tooling lower mold grooves 13, and three tooling lower mold grooves 13 are provided in the figure. Three elastic O-rings are respectively installed in the three tooling lower mold grooves 13.

[0035] In addition, in this embodiment, when shaping the inner diameter of the generator stator, the servo mechanism 1 controls the pressure head 2 to press on the tooling upper mold 3. The servo mechanism 1 can be a power mechanism such as an oil hydraulic press, a motor, or a pneumatic motor. Since the outer surface of the tooling upper mold 3 is adapted to the shape of the inner surface of the tooling lower mold assembly 11, the tooling lower mold assembly 11 expands outward under the pressure of the tooling upper mold 3. At this time, the state of the tooling upper mold 3 and the tooling lower mold 5 combined shaping is as shown in FIG. Figure 3 As shown, the inner diameter shaping of the generator stator is completed. Since the lower tooling mold 5 is provided with an elastic element 12, the lower tooling mold 5 can be restored to its original shape after the inner diameter shaping is completed. At this time, the upper mold 3 and the lower tooling mold 5 are combined and shaped as shown in FIG. Figure 2 shown.

[0036] like Figure 1 and Figure 4 As shown, the generator stator inner diameter shaping device also includes a placement table 6, which is cylindrical, and the generator stator is fixed on the placement table 6.

[0037] like Figure 1 and Figure 5As shown, in other embodiments, the placing table 6 is also equipped with one or more heightening members 7, and at least two placing table grooves 8 are arranged on the top of the placing table 6. The heightening member 7 is cylindrical, and at least two heightening member grooves 9 are arranged on the top of the heightening member 7, and a heightening member protrusion 10 corresponding to the placing table groove 8 is arranged on the bottom. In addition, the heightening member groove 9 corresponds to the heightening protrusion 10, so that multiple heightening members 7 are connected. The stability of the connection between the placing table 6 and the heightening member 7 is increased, and the accuracy of the shaping of the inner diameter of the generator stator is improved. In this embodiment, the placing table 6 is provided with two placing table grooves 8, and is equipped with a heightening member 7. The heightening member 7 is also provided with two heightening member protrusions 10 corresponding to the placing table groove 8, and two heightening member grooves 9 are provided to reserve the connection of other heightening members 7.

[0038] In addition, if Fig.10 As shown, in other embodiments, a force-bearing platform 14 is further provided on the top of the tooling upper mold 3, and a rolling mesh pattern 15 is provided on the outer surface of the force-bearing platform 14. The provision of the force-bearing platform 14 can make the force on the tooling upper mold 3 more uniform, and the rolling mesh pattern 15 provided on the outer surface of the force-bearing platform 14 can increase the friction between the operator's hand and the tooling upper mold 3, so that the operator can easily recycle the tooling upper mold 3 after completing the shaping of the inner diameter of the generator stator.

[0039] The above description is only a preferred specific implementation of the present invention. Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
