[0029] Combination Figure 1-4 As shown, the utility model provides a motor rotor sleeve press machine, comprising a support mechanism 100, a feeding mechanism 200 and a press mechanism 300, wherein the support mechanism 100 comprises a workbench 110, a plurality of deep grooves 120 and a plurality of shallow grooves 130 opened on the top of the workbench 110, and the plurality of shallow grooves 130 are respectively connected to the interior of the plurality of deep grooves 120;

[0030] A feeding mechanism 200, the feeding mechanism 200 comprises a material frame 210 attached to the top of the workbench 110, a threaded rod 220 movably mounted on the top of the workbench 110, and a motor 230 connected between the workbench 110 and the threaded rod 220, wherein the threaded rod 220 transversely penetrates the rear side of the material frame 210;

[0031] The press-fitting mechanism 300 includes a plate body 310 connected to the front side of the material frame 210 and a hydraulic cylinder 320 penetrating the plate body 310 .

[0032] Furthermore, the multiple deep grooves 120 are arranged in a row at equal intervals. This layout design ensures that the hydraulic cylinder 320 can accurately reach the front side of the shallow groove 130 before the material frame 210 is loaded with materials, and then perform the press-fitting operation.

[0033] Furthermore, a partition 400 is installed inside the material frame 210, and the partition 400 divides the inside of the material frame 210 into a rotor shaft cavity and a sleeve cavity. The partition 400 can be provided to separate the rotor shaft and the sleeve, so that the press-fitting operation can continue smoothly.

[0034] Furthermore, the rotor shaft cavity is located at the front side of the sleeve cavity, and the rotor shaft cavity is located at the top of the shallow groove 130. With this layout design, the movable end of the hydraulic cylinder 320 is limited to only squeeze the rotor shaft, avoiding air pressure when the hydraulic cylinder 320 contacts the sleeve. Embodiment 2

[0035] Combination Figure 1-4 As shown, on the basis of embodiment one, the motor 230 and the hydraulic cylinder 320 are electrically connected to the external PLC. The control method of the utility model is to realize automatic control through the external PLC electricity. The control circuit of the external PLC electricity can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail. The use of this structural design can improve the intelligence of the device and improve the comfort of use. Embodiment 3

[0036] Combination Figure 1 As shown, in the above embodiment, a guide rod 500 is sleeved on the top of the workbench 110, and the guide rod 500 is located on the top of the plate body 310. The guide rod 500 transversely penetrates the front side of the material frame 210. The guide rod 500 can make the material frame 210 move smoothly.

[0037] The working principle and use process of the utility model are as follows: when the device is put into actual use, the external PLC starts the motor 230 first, and then the threaded rod 220 rotates, and the material frame 210 is translated from the left side of the workbench 110 to the right side of the workbench 110, and then each deep groove 120 is filled with a sleeve, and each shallow groove 130 is filled with a stator shaft. During this process, once the hydraulic cylinder 320 is located in front of a shallow groove 130, the external PLC will shut down the motor 230 and then start the hydraulic cylinder 320. Then the hydraulic cylinder 320 presses the rotor shaft into the sleeve, thereby completing the assembly of the two, and then repeating the pressing steps. Here, the workers can safely remove the assembled workpiece to avoid the formed workpiece affecting the subsequent feeding operation. The various steps are coordinated smoothly and continuously, thereby improving the pressing efficiency.
