[0059] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0060] like Figures 1 to 6 As shown, a motor press-fitting device of the utility model includes:
[0061] A base 1 is provided with a positioning seat 110, and the motor housing is placed on the positioning seat 110;
[0062] The transport member 2 is arranged above the base 1 and is used to transport the rotor of the motor;
[0063] A first pressing member 3 is provided below the transport member 2 and coaxially with the transport member 2. The first pressing member 3 is provided with a passage for accommodating the rotor. The first pressing member 3 has a first motion state, a second motion state, and a third motion state.
[0064] The first motion state is the motion state when the first clamping member 3 is located under the transport member 2 and receives the rotor, the second motion state is the motion state when the first clamping member 3 rolls, and the third motion state is the motion state when the first clamping member 3 completes the flipping and presses the rotor against the motor housing placed on the positioning seat 110.
[0065] The transporting member 2 transports the rotor to the first pressing member 3 , which clamps the rotor and rotates it 180 degrees. After the rotor is turned over, the first pressing member 3 presses the rotor against the motor housing placed on the positioning seat 110 .
[0066] The first pressing member 3 of this solution also includes:
[0067] The support base 310 is arranged above the base 1. The support base 310 is provided with a gas channel 311 and an opening 312 connected to the gas channel 311. A fixing rod 313 is provided in the opening 312. The support base 310 is used to press the rotor;
[0068] A connecting rod 320, one end of which is sleeved on the support base 310;
[0069] A clamping arm 330 is rotatably sleeved on the fixed rod 313 and is used to clamp the rotor;
[0070] A first top column 340 , which is movably inserted into the support base 310 and is used to abut against the clamping arm 330 ;
[0071] A second top column 350 , which is movably disposed in the gas passage 311 and is used to abut against the first top column 340 ;
[0072] The first driving member 360 is disposed above the base 1 and is used to drive the first pressing member 3 .
[0073] like Figure 5 As shown, the transport member 2 transports the rotor to the first pressing member 3, and the gas is input into the gas channel 311, driving the second top column 350 to abut against the first top column 340 and drive the first top column 340 to move, so that the first top column 340 abuts against the clamping arm rod 330 and drives the clamping arm rod 330 to rotate, so that the end of the clamping arm rod 330 away from the first top column 340 abuts against the rotor and fixes the rotor in the first pressing member 3, and the first driving member 360 drives the first pressing member 3 to drive the rotor to rotate. After the flipping is completed, the first pressing member 3 presses the rotor against the motor housing placed on the positioning seat 110.
[0074] The transport part 2 of this scheme also includes:
[0075] A first support frame 210, which is disposed above the base 1 and has a passage;
[0076] Support columns 220, at least three support columns 220 are provided, and at least three support columns 220 are spaced apart and arranged on the first support frame 210;
[0077] Connecting columns, which are layered and inserted into adjacent supporting columns 220;
[0078] Support plates 230, at least three of which are provided. The at least three support plates 230 are rotatably sleeved on the connecting column, and a through hole 231 is provided at the upper end of the support plate 230;
[0079] A tensile wire 240 is inserted into the through hole 231 and has a wire section 241 disposed on the tensile wire 240. The wire section 241 is located above the support plate 230.
[0080] The transport switch 250 is arranged above the base 1 , and the stretch line 240 is connected to the transport switch 250 . The transport switch 250 is used to control the tightness of the stretch line 240 .
[0081] like Figure 3 As shown, when the stretching line 240 is taut, the wire segment 241 applies a thrust to the through hole 231, causing the support plate 230 to tilt, so that the lower end of the support plate 230 abuts against the rotor, fixing the rotor in the transport member 2. After the transport switch 250 is turned, the stretching line 240 is relaxed, and the thrust applied to the through hole 231 by the wire segment 241 disappears. The support plate 230 rotates on the connecting column under the action of its own gravity, causing the lower end of the support plate 230 to rotate and separate from the rotor, presenting an open and closed state, so that the rotor can move in the transport member 2.
[0082] This solution also includes: a first gear 4, which is sleeved on the end of the connecting rod 320 away from the support seat 310; a first rack 5, which is arranged above the base 1 and movably meshed with the first gear 4.
[0083] like Figure 2 As shown, after the first driving member 360 drives the first clamping member 3 to bring the first gear 4 into contact with the first rack 5, the first gear 4 rotates and moves downward on the first rack 5, driving the first clamping member 3 to rotate and move downward. When the first gear 4 is separated from the first rack 5, the first clamping member 3 completes the flipping.
[0084] This program also includes:
[0085] Sensor 6, the sensor 6 is disposed above the base 1, and the sensor 6 is electrically connected to the first driving member 360;
[0086] A travel baffle 7 is movably abutted against the sensing end of the sensor 6;
[0087] The stopper 8 is sleeved on one end of the connecting rod 320 away from the supporting seat 310 and is located on the side of the first gear 4.
[0088] like Figure 2As shown, after the first pressing member 3 has completed press-fitting the rotor, the first driving member 360 drives the first pressing member 3 to reset, driving the first gear 4 to contact the first rack 5. Subsequently, the first gear 4 rotates and moves upward on the first rack 5, driving the block 8 to rotate and move upward. The block 8 contacts the travel baffle 6 and pushes the travel baffle 6, so that the travel baffle 6 contacts the sensor 7. The sensor 7 transmits an electrical signal to the first driving member 360, causing the first driving member 360 to drive the first pressing member 3 to move in the opposite direction, pressing the motor cover manually placed on the motor housing. After the first pressing member 3 has completed press-fitting the motor cover, the first driving member 360 drives the first pressing member 3 to reset again. By setting the travel baffle 6 and the sensor 7 to a delayed disconnection, the block 8 no longer touches the travel baffle 6 during the resetting process of the first pressing member 3, so that the first pressing member 3 can complete the resetting.
[0089] This program also includes:
[0090] The second pressing member 9 is sleeved on the positioning seat 110 and is used to press the lower end of the motor housing and the rotating shaft of the rotor. The second pressing member 9 includes:
[0091] A disc 910, wherein the disc 910 is provided with a groove 911;
[0092] The gear ring 920 is rotatably disposed on the inner wall of the groove 911;
[0093] A second rack 930, at least three of which are provided. The second rack 930 is movably inserted on the disc 910 from the side end of the disc 910;
[0094] A second gear 940 is rotatably disposed on the groove 911 , and the second gear 940 is meshed with the ring gear 920 and the second rack 930 ;
[0095] At least two third gears 950 are provided. The third gears 950 are rotatably mounted on the groove 911 . The third gears 950 correspond to the ring gear 920 and the remaining second racks 930 and mesh with each other.
[0096] The second driving member is disposed on the disc 910 and is used to drive the second gear 940 .
[0097] like Figure 6 As shown, the ring gear 920, the second gear 940 and the third gear 950 form a planetary gear. The second driving member drives the second gear 940 to rotate, which drives the ring gear 920 to rotate, and the third gear 950 to rotate. The rotation of the second gear 940 and the third gear 950 drives the second rack 930 to move, thereby pressing the motor housing and making the rotor shaft and the motor housing have an interference fit.
[0098] This program also includes:
[0099] The detection member 10 is provided on the base 1 and is used to detect the motor. The detection member 10 includes:
[0100] The power contact 1010 is movably provided on the base 1 and is used to contact the contact point on the upper cover of the motor;
[0101] A third driving member 1020 is provided above the base 1 and is used to drive the electrical contact 1010;
[0102] The detection circuit 1030 is provided on the base 1 . The detection circuit 1030 is connected to the power contact 1010 . The detection circuit 1030 is used to supply power to the power contact 1010 .
[0103] After the motor is press-assembled, the detection circuit 1030 supplies power to the power contact 1010 , and the third driving member 1020 drives the power contact 1010 to make contact with the contact point of the motor cover, thereby running the motor and detecting the motor.
[0104] This program also includes:
[0105] The second support frame 11 is set on the base 1, and the second support frame 11 is used to support the transport member 2 and the first pressing member 3; the guide column 12 is inserted into the second support frame 11, and the guide column 12 is used to guide the movement of the first pressing member 3.
[0106] The first driving member 360 drives the first pressing member 3 to move, the second supporting frame 11 supports the first pressing member 3 to ensure the stability of the movement of the first pressing member 3, and the guide column 12 guides the movement of the first pressing member 3 to ensure that the first pressing member 3 can move along the predetermined path.
[0107] By setting a transport part 2 to transport the rotor to the first pressing part 3, the first pressing part 3 moves and flips, transports the rotor to the positioning seat 110, and presses the rotor and the motor housing. The transport part 2, the first pressing part 3 and the motor housing are on the same axis. The advantage of this design is that when the first pressing part 3 presses the rotor and the motor housing, the coaxiality deviation of the rotor and the motor housing is very small, so that the motor can operate normally and have good performance.
