Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a special tooling for roller wire embedding. Background Art

[0002] In the manufacturing process of permanent magnet drum, the process of fixing the coil in the stator is called wire embedding, and the position where the coil is placed is called wire slot. The wire slot is evenly distributed along the circumference of the stator. During the wire embedding process, the stator needs to be continuously rotated to facilitate the wire embedding operation. After the wire embedding is completed, the stator needs to be transferred to the next process. Large-sized stators are usually transported by cranes, and the number of cranes in the workshop is limited, which affects the efficiency of stator transportation. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to solve the problem that in the prior art, after the wire embedding is completed, the stator needs to be transferred to the next process, and large-sized stators are usually transported by cranes, and the number of cranes in the workshop is limited, which affects the stator transfer efficiency. A special tooling for roller wire embedding is now provided.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a special tool for roller wire embedding, comprising two brackets arranged opposite to each other, each bracket having a roller assembly on the top, one of which is a driving wheel assembly and the other is a driven wheel assembly, the roller assembly is used to support the stator assembly, and the stator assembly is driven to rotate by the driving wheel assembly, so as to improve the wire embedding efficiency;

[0005] A telescopic beam is provided between the two brackets for driving the two brackets to move closer or farther away, the telescopic beam comprises a screw-nut mechanism and a telescopic inner beam and a telescopic outer beam which are slidably mounted, one end of the telescopic outer beam is fixed to one of the brackets, and the other end is for the telescopic inner beam to pass through, one end of the telescopic inner beam is fixed to the other bracket and the output end of the screw-nut mechanism is connected to the telescopic inner beam, the telescopic inner beam is driven to slide in the telescopic outer beam by the screw-nut mechanism, the distance between the two brackets can be adjusted to adapt to stator assemblies of different lengths, thereby improving the versatility of the tooling, in addition, the tooling structure formed by the bracket and the telescopic beam can reduce the weight of the tooling itself, and the telescopic beam can cooperate with AGV trolleys, forklifts, etc. to realize various modes of transportation, and the stator assembly and the tooling can be transported to the workstation at the same time to improve the transportation efficiency.

[0006] The above technical solution uses the telescopic beam between the two brackets to adjust the distance between the two brackets to adapt to stator assemblies of different lengths, thereby improving the versatility of the tooling. In addition, the tooling structure composed of the bracket and the telescopic beam can reduce the weight of the tooling itself, and the telescopic beam can cooperate with AGV carts, forklifts, etc. to realize various modes of transportation, and the stator assembly and the tooling can be transported to the work station at the same time to improve the transportation efficiency.

[0007] Furthermore, the driving wheel assembly includes a brake motor, two driving rollers and a transmission chain for connecting the two driving rollers; during the wire embedding process, due to the gravity of the coil, the gravity of the stator's wire-embedded part and the unembedded part is unbalanced, causing the roller to rotate, affecting the workers' wire embedding operation. The workers also need to make adjustments constantly, reducing work efficiency. The use of a brake motor can lock the roller to avoid this situation.

[0008] Furthermore, the stator assembly includes a drum and a main shaft passing through the inside of the drum, both ends of the main shaft are mounted on the roller assembly, and the end of the main shaft with a keyway is sleeved with a stator sleeve to prevent the keyway from directly contacting the roller assembly and causing jamming; power can be transmitted to the stator sleeve through the contact between the stator sleeve and the roller assembly, thereby driving the drum to rotate.

[0009] Furthermore, a threaded hole is provided on the stator sleeve, and the threaded hole is a countersunk hole, and the threaded hole is directly opposite to the keyway on the main shaft. The bolt passes through the threaded hole and extends into the keyway to fix the stator sleeve and the stator assembly, so that the two rotate synchronously.

[0010] Furthermore, there are two telescopic beams and the two telescopic beams are arranged side by side. The two telescopic beams can bear the force evenly, thereby improving the load-bearing capacity of the bracket.

[0011] Furthermore, a rocker is connected to the input end of one of the lead screw and nut mechanisms, and a synchronous chain is connected between the two lead screw and nut mechanisms; the rocker is rotated to drive the two lead screws to rotate synchronously through the synchronous chain, thereby realizing synchronous extension and retraction of the two telescopic beams.

[0012] Furthermore, a foot support weldment is provided at the bottom of each bracket, and casters are installed at the bottom of the foot support weldment to facilitate the transportation of the tooling itself and the adjustment of the distance between the two brackets.

[0013] Furthermore, the telescopic outer beam and the telescopic inner beam are both provided with slots along their length direction, so as to facilitate the installation of the screw nut mechanism and the observation of the positions of the telescopic outer beam and the telescopic inner beam.

[0014] The beneficial effects of the utility model are as follows: the utility model utilizes the telescopic beam between the two brackets to adjust the distance between the two brackets so as to adapt to stator assemblies of different lengths, thereby improving the versatility of the tooling; in addition, the tooling structure formed by the brackets and the telescopic beam can reduce the weight of the tooling itself, and the telescopic beam can cooperate with AGV trolleys, forklifts, etc. to realize various modes of transportation, and the stator assembly and the tooling can be transported to the work station at the same time to improve the transportation efficiency.
