SUMMERY OF THE UTILITY MODEL
The utility model provides a crimping tool for a lower bearing of a motor, which aims to solve the problem that the rotor assembly is difficult to take out after pressing the bearing, and comprises a base, the base is provided with a mounting seat for placing a motor rotor component and a bracket, the support is provided with a top block for placing a bearing, the mounting seat is provided with a sliding groove in the height direction, the base is provided with a guide post, the bracket is arranged on the guide post in a sliding way, the bracket is fixed with a sleeve, a shifting sheet is arranged on the guide post in a sliding manner, a first spring is sleeved on the guide post, one end of the first spring is fixed on the base, the other end of the first spring is fixed with the shifting sheet, the shifting piece is arranged in the sliding groove in a sliding mode and abuts against the magnetic steel of the rotor assembly, and the support is further provided with a cylinder used for driving the support to move up and down.
Preferably, the top block is provided with an installation groove, and the size of the installation groove corresponds to that of the bearing. Be equipped with magnet in the mounting groove, magnet holds the bearing, prevents to push down the in-process, and the bearing drops.
Furthermore, a guide hole is formed in the support, and the support is arranged on the guide pillar in a sliding mode through the guide hole.
Preferably, a fixing hole for placing a motor shaft of the rotor assembly is formed in the mounting seat, a second spring is arranged in the fixing hole, and one end of the second spring penetrates through the fixing hole and is fixedly arranged on the base. The second spring contacts with the motor shaft when pressing the bearing, has played the cushioning effect, prevents that the motor shaft from impacting the base fast under the pressurized state, causes motor shaft and base to damage, has improved life.
Has the advantages that: the utility model discloses simple structure, the simple operation makes things convenient for the operator to take out the rotor subassembly of having pressed the bearing, can not have to press the bearing and appear blocking dead phenomenon, has improved production efficiency.

Detailed Description
Example one
As shown in the figure, the crimping tool for the lower bearing of the motor comprises a base 1, wherein a mounting seat 2 for placing a rotor assembly of the motor is arranged on the base 1, the base 1 is also provided with a bracket 5, the bracket 5 is provided with a top block 15 for placing the bearing 11, the mounting seat 2 is provided with a sliding groove 9 in the height direction, the base seat 1 is provided with a guide post 4, the bracket 5 is arranged on the guide post 4 in a sliding way, a sleeve 16 is fixed on the bracket 5, a shifting sheet 8 is arranged on the guide post 4 in a sliding way, a first spring 13 is also sleeved on the guide post 4, one end of the first spring 13 is fixed on the base 1, the other end is fixed with the shifting piece 8, the poking piece 8 is arranged in the sliding groove 9 in a sliding mode and abuts against the magnetic steel 10 of the rotor assembly, and the support 5 is further provided with an air cylinder used for driving the support 5 to move up and down.
The top block 15 is provided with an installation groove, and the size of the installation groove corresponds to that of the bearing 11. A guide hole 6 is formed in the bracket 5, and the bracket 5 is slidably arranged on the guide post 4 through the guide hole 6. A fixing hole 7 for placing a motor shaft 12 of the rotor assembly is formed in the mounting base 2, a second spring 14 is arranged in the fixing hole 7, and one end of the second spring 14 penetrates through the fixing hole 7 to be fixedly arranged on the base 1.
The working principle is as follows: the rotor assembly is partially placed in the mounting seat 2, a motor shaft 12 in the rotor assembly abuts against a second spring 14 in the fixing hole 7, and the magnetic steel 10 abuts against the poking piece 8. Put bearing 11 in mounting groove 3 of kicking block 15, owing to be equipped with magnet in the mounting groove 3, adsorb bearing 11, start the cylinder for support 5 moves down, presses bearing 11 to motor shaft 12 on gradually, presses the assigned position until bearing 11, and whole rotor subassembly is pressed completely in mount pad 2 this moment, and sleeve 16 pushes down the in-process at support 5, pushes down plectrum 8 and makes first spring 13 on the guide pillar 4 compressed. Then the piston of cylinder moves back, and first spring 13 rebounds rapidly, and first spring 13 is upwards bounced with plectrum 8, because plectrum 8 and magnet steel 10 contact, plectrum 8 supports magnet steel 10 and lifts the rotor subassembly upwards, and the operator only need will press the rotor subassembly of good bearing 11 gently one and take, continues to push down a bearing 11.
