Description

Technical Field

[0001] The utility model relates to a support frame for transporting medium and small-sized motor rotors, belonging to the technical field of motor production and transportation equipment. Background Art

[0002] Motors are the main power equipment that must be used in modern enterprises, so the production volume of motors is very large. During the production process of motors, a large number of stator and rotor spare parts need to be circulated and transported. At the same time, during the motor off-line maintenance work of motor users, after the motor stator and rotor are disassembled, the motor rotor often appears in situations such as grinding, overheating adhesion, rolling keys, cutting, and shaft bending in parts such as the bearing journal and shaft extension, and needs to be loaded and sent out for processing and repair. Therefore, whether it is motor production or maintenance, the motor rotor needs to be transported and circulated. Among them, especially for YZR wound rotors and DC motor rotors, the collector rings and commutators need to be precision turned and repaired. Moreover, the rotor coils, iron cores, collector rings, and commutators need to avoid bumps during transportation and circulation, prevent the coil wires from breaking, and prevent the insulation from being damaged, which may cause major repairs to the windings and increase the maintenance cost. Currently, during the transportation of various medium and small-sized motor rotors, there is no special transportation support frame. Instead, materials such as wooden blocks and wooden boards are temporarily used for support and partition to prevent the motor rotor from shaking, toppling, and bumping. This method is very backward. It not only takes time and effort, reduces the transportation and loading efficiency, but also inevitably causes the motor rotor to be not firmly fixed and suffer secondary damage during transportation, increasing the maintenance cost. Therefore, it is very necessary to improve the method of transporting the motor rotor. Content of the Utility Model

Fixing nuts are welded on the steel plate of the bottom plate frame below the positioning double convex grooves, and the fixing bolts pass through the bolt holes in the centers of the one-way positioning blocks and two-way positioning blocks and are connected to the fixing nuts.

[0006] For the above support frame for transporting medium and small-sized motor rotors, on both sides of the bottom surface of the cuboid wooden blocks of the one-way positioning blocks and two-way positioning blocks, there are vertical positioning card double grooves along the length direction of the positioning blocks. The edges of the positioning double convex grooves are inserted into the positioning card double grooves of the one-way positioning blocks and two-way positioning blocks, and the positioning double convex grooves are welded to the bottom plate frame to play a role in fixing the positioning blocks.

[0007] For the above support frame for transporting medium and small-sized motor rotors, the upper ends of the cuboids of the one-way positioning blocks and two-way positioning blocks are arc-shaped. At the lower ends of the bolt holes of the one-way positioning blocks and two-way positioning blocks, there are nut grooves for placing the fixing nuts, and at the upper ends of the bolt holes, there are nut grooves for placing the fixing bolts.
