When the roller 99 reaches the second horizontal groove 97, the clamp mounting seat 93 and the clamp 94 rotate by 90°. The clamp 94 is in a horizontal state, and the rotor core is in a vertical state. Similarly, when the clamp mounting block 92, the clamp mounting seat 93 and the clamp 94 move forward, the clamp 94 returns to the vertical state.

[0043] With reference to Figure 1 , Figure 3 , Figure 5 to Figure 10The design principle of the present application is as follows: the clamp 94 clamps the rotor core 34, the clamp mounting block 92, the clamp mounting seat 93 and the clamp 94 move backward to send the rotor core 34 to the upper side of the core tooling 7, then the core tooling 7 rises to support the rotor core 34, and after the core tooling 7 supports the rotor core 34, it is lowered to make the rotor core 34 located in the space surrounded by the seven separation blocks 5, and at the same time, the clamp mounting block 92, the clamp mounting seat 93 and the clamp 94 are reset, then the pressing cylinder 8 is lowered to drive the seven pressing plates 6 to move inward, so that the seven pressing plates 6 simultaneously close and flatten the seven horn-shaped protrusions 39, then the pressing cylinder 8 is raised, the seven pressing plates 6 are reset, the core tooling 7 rotates by a certain angle, the pressing cylinder 8 is lowered again to continue to close and flatten the next group of seven horn-shaped protrusions 39, and the pressing cylinder 8 repeatedly rises and falls to realize the closing and flattening of all the horn-shaped protrusions 39 of the rotor core 34. In the embodiment, the seven pressing plates 6 move inward three times to complete the closing and flattening of all the horn-shaped protrusions 39 of the rotor core 34.

[0044] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application using this concept shall be regarded as an infringement of the protection scope of the present application.

The piston rod of the cylinder extends out of the bottom surface of the cylinder mounting plate and connects to the top of the flange connecting seat. The bottom of the connecting cylinder connects to the top of the pressure cylinder.

6. The motor rotor sealing machine as described in claim 5, characterized in that: The feeding device includes a clamp mounting plate, a clamp mounting block, a clamp mounting seat, and an openable clamp. The clamp mounting plate is vertically mounted above the first mounting plate. The clamp mounting block is movable back and forth along the clamp mounting plate. The clamp mounting seat is rotatably connected to the clamp mounting block. The clamp is connected to the clamp mounting seat. The side of the clamp mounting plate near the mounting plate has a first horizontal groove, an inclined groove, and a second horizontal groove that are connected sequentially from front to back. The second horizontal groove is located obliquely above the first horizontal groove. The clamp mounting seat has a mounting rod facing the clamp mounting plate. A roller is connected to the end of the mounting rod near the clamp mounting plate. The roller can slide in the first horizontal groove, the inclined groove, and the second horizontal groove. When the roller is in the first horizontal groove, the clamp is in a vertical state. When the roller is in the second horizontal groove, the clamp is in a horizontal state.

7. A motor rotor sealing machine as described in claim 6, characterized in that: The clamp mounting plate has two guide rod blocks arranged in a front-to-back configuration on the side away from the mounting plate. The two guide rod blocks are respectively for two second connecting rods to pass through. The top surface of the first mounting plate is connected to a second cylinder, and the piston rod of the second cylinder faces upward and is connected to the clamp mounting plate.

8. A motor rotor sealing machine as described in claim 6, characterized in that: A rodless cylinder is provided on the side of the clamp mounting plate near the mounting plate. The slide of the rodless cylinder is connected to the clamp mounting block. A slide rail is provided along the length direction on the side of the clamp mounting plate near the mounting plate. The slide rail is provided with a slider that slides with it. The slider is connected to the clamp mounting block. A bearing is provided inside the clamp mounting block. A shaft passes through the bearing and is connected to the clamp mounting seat.
