[0005] The bottom plate is provided with a T-shaped slot, on which two V-shaped brackets for placing the motor rotor are installed through T-shaped bolts, and the front and rear ends of the V-shaped bracket are bent upwards and oppositely, and the V-shaped bracket can slide left and right along the T-shaped slot;

[0006] The workbench is provided with two bearing placement slots, two feeding heads, two guide heads and two pressing heads, and each component is symmetrically arranged on the left and right sides of the bottom plate;

[0007] A guide tube is fixed at one end of the bearing placement groove, and an opening is provided at the other end for the piston rod of the feeding head to extend into, and the guide tube is connected to the bearing placement groove;

[0008] A bearing pressing tool is installed on the piston rod of the press-in head and the piston rod is opposite to the motor rotor on the left and right. A bearing feeding groove is opened on the bearing pressing tool along the radial direction of the piston rod of the press-in head. The piston rod of the guide head can extend into the guide tube and push the bearing into the bearing feeding groove.

[0009] Furthermore, the bearing placement groove is arranged perpendicular to the guide tube.

[0010] Furthermore, the bearing feeding groove on the pressure bearing tooling is opened obliquely upward along the radial direction of the piston rod pressed into the top.

[0011] The motor rotor bearing pressing device provided by the utility model can automatically transport the bearing from the bearing placement groove to the pressing station by utilizing the cooperation of multiple pins, the bearing placement groove and the guide tube, and then automatically press the bearing into the rotor, thereby saving most of the manual steps and improving the processing efficiency.

All similar structures and similar changes of the utility model should be included in the protection scope of the utility model. The semicolons in the utility model all represent the relationship of and.

[0017] like Figure 1-Figure 4 As shown, a motor rotor bearing pressure device provided by an embodiment of the utility model includes a workbench 13, on which a bottom plate 3 is fixed, and is characterized in that:

[0018] The bottom plate 3 is provided with a T-shaped slot, on which two V-shaped brackets 4 for placing the motor rotor are installed through T-shaped bolts 5, and the front and rear ends of the V-shaped bracket 4 are bent upwards and oppositely, and the V-shaped bracket 4 can slide left and right along the T-shaped slot;

[0019] The workbench 13 is provided with two bearing placement grooves 10, two feeding plugs 8, two guide plugs 11 and two pressing plugs 7, and each component is symmetrically arranged on the left and right sides of the bottom plate 3;

[0020] A guide tube 12 is fixed at one end of the bearing placement groove 10, and an opening is provided at the other end for the piston rod of the feeding head 8 to extend into, and the guide tube 12 is connected to the bearing placement groove 10;

[0021] A bearing pressing tool 6 is installed on the piston rod of the press-in head 7, and the piston rod is opposite to the motor rotor 1 on the left and right. A bearing feeding groove 9 is opened on the bearing pressing tool 6 along the radial direction of the piston rod of the press-in head 7.
