Description

Technical Field

[0001] The utility model relates to the technical field of remanufacturing starters, in particular to a starter rotor commutator removal device. Background Art

[0002] During the production and processing of remanufactured starter rotors, rotors with unqualified performance may be produced. It is necessary to remove the commutator that has been spot-welded with the rotor enameled wire, leaving the rotor body and then reprocessing it. The commutator and the rotor shaft are interference fit. If the commutator that has been spot-welded is disassembled by direct turning and hammering, it will not only be easy to damage the rotor enameled wire and the rotor shaft, but it will also be difficult to separate the commutator from the rotor shaft. The processing is difficult and inefficient. There is a risk of worker injury during the operation, which can easily affect production efficiency and product quality.

[0003] The patent document with announcement number CN217991573U discloses a quick disassembly device for a rotor commutator, including a base, the base is connected to a mounting plate through mounting columns at the four corners of the top, a cylinder is installed on the top of the mounting plate, a stamping mechanism is arranged at the output end of the cylinder, the top of the base is fixedly connected to a slot seat through a connecting rod, and a removal target part is installed in the U-shaped slot of the slot seat; the stamping mechanism includes a material withdrawal sleeve, a punch, a punch body and a spring, the punch is fixedly connected to the middle of one end of the punch body, and the spring is fixedly connected to the side wall of the punch body. Although this device avoids the entire complicated knocking process of removing the rotor commutator, the device does not process the connection between the rotor commutator and the rotor shaft before disassembly, and directly disassembles the rotor, which is not easy to separate the rotor commutator from the rotor shaft, and may also cause the rotor shaft to deform due to multiple impacts, affecting the subsequent reuse and reprocessing of the rotor body.

The impact hammer servo mechanism controls the impact hammer head to make the extension rod move upward, and extends out of the extension rod groove to impact the rotor shaft of the starter rotor after burning, so that the rotor commutator is separated from the rotor shaft.

[0008] Furthermore, the workbench is also provided with a striking platform, and the starter rotor whose rotor commutator is not fully removed is impacted on the striking platform, so that the rotor commutator and the starter rotor are fully separated.

[0011] Preferably, the fireproof layer is fireproof cotton or fireproof tile.

[0029] like Figure 1 Figure 2As shown, the utility model discloses a starter rotor commutator removal device, comprising: a workbench 1, a workpiece table 2, a burning box 3, and an impact hammer servo mechanism 5. The workbench 1 is provided with an extension rod slot 10 and a spray gun slot 11. The burning box 3 is arranged on the top of the spray gun slot 11, and the burning box 3 is equipped with a spray gun 4. The spray gun 4 is installed in the spray gun slot 11 to burn the starter rotor. Figure 1 , Figure 4 and Figure 5 shown.

[0030] The workpiece table 2 is arranged at the top of the extension rod groove 10, and the workpiece table 2 includes: a first V-shaped clamp block 12, a U-shaped table 13, and a second V-shaped clamp block 14. The first V-shaped clamp block 12 is fixedly arranged at the concave position of the U-shaped table 13, and the second V-shaped clamp block 14 is equipped with a workpiece table servo mechanism 16 and a connector 15. The workpiece table servo mechanism 16 is connected to the second V-shaped clamp block 14 through the connector 15. The second V-shaped clamp block 14 moves along the U-shaped table 13 toward the first V-shaped clamp block 12 under the control of the workpiece table servo mechanism 16, and fixes the burnt starter rotor just above the extension rod groove 10, as shown in FIG. Figure 3 shown.

[0031] In this embodiment, the starter rotor is placed in the burning box 3, and the spot welding connection between the rotor commutator and the rotor shaft is burned. After the burning is completed, the burned starter rotor is taken out, and the end equipped with the rotor commutator is inserted into the workpiece table 2. The second V-shaped clamp 14 moves toward the first V-shaped clamp 12 under the control of the workpiece table servo mechanism 16, and the burned starter rotor is fixed directly above the extension rod slot 10.

[0032] In addition, in the present embodiment, the first V-shaped clamp block 12 and the second V-shaped clamp block 14 are both provided with textures on the V-shaped surfaces, so as to increase the friction between the starter rotor and the first V-shaped clamp block 12 and the second V-shaped clamp block 14 .

[0033] The impact hammer servo mechanism 5 is provided with an impact hammer head 6, and an extension rod 7 is provided on the top of the impact hammer head 6.
