Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.
Referring to fig. 1-5, an embodiment of a pre-shaping device of the present invention includes a machine body 1, wherein a locking device and a shaping device are sequentially arranged on the machine body 1, a mechanical arm is used to place a wound stator and a fixture for locking the stator in the locking device, and then the locking device is driven to move to a station of the shaping device, and pre-shaping of a stator coil is achieved through cooperation of the locking device and the shaping device.
The locking device comprises a fixed mould 2 and at least two pressing plates 4, wherein the fixed mould 2 is arranged on the machine body 1, and meanwhile, a containing cavity for placing a stator and a clamp is formed in the fixed mould 2. The pressing plate 4 is embedded in the fixed mold 2 and disposed around the accommodating chamber. The pressure plate 4 is connected with a first driving member capable of pushing the pressure plate 4 to approach or depart from the accommodating cavity. When the pressing plate 4 is pushed by the first driving piece to approach the accommodating cavity and is attached to the outer side wall of the fixing clamp of the stator, the purpose of locking the stator by the pressing plate 4 can be achieved, and the pressing plate 4 is located outside the stator coil. When the pressing plate 4 is far away from the accommodating cavity under the pulling of the first driving piece, the pressing plate 4 is separated from the fixing clamp, so that the locking of the stator position is released. The platen 4 in this embodiment is arc-shaped to increase the area when the platen 4 contacts with the fixing jig, stability when the platen 4 and the stator are locked is increased. In this embodiment, the bottom of the new energy stator groove is deeper, and the outer diameter of the coil is larger, even larger than the outer diameter of the stator after the coil is inserted. Therefore, the stator after coil insertion cannot meet the working procedures of pre-shaping, subsequent intermediate shaping and the like, and the outer diameter of the coil needs to be reduced by using the pressing plate 4 during pre-shaping, so that the stator can be ensured to be separated from a stator tool, and the processing of the subsequent working procedures is ensured.
The first driving member includes a rotary disk 5, and the rotary disk 5 is rotatably provided on the stationary mold 2. The turntable 5 is provided with an arc-shaped chute 51, and the pressing plate 4 is connected with a sliding block 41 matched with the chute 51, and the sliding block 41 can be embedded in the chute 51 to move. In this embodiment, the sliding grooves 51 are all arc-shaped, and two ends of the sliding groove 51 are located in different circumferences, the end of the sliding groove 51 close to the accommodating cavity is denoted as a first end 511, and the end of the sliding groove 51 far from the accommodating cavity is denoted as a second end 512. When the slider 41 is close to the first end 511, all the pressing blocks are close to each other to lock the stator, and when the slider 41 is close to the second end 512, all the pressing blocks are far away from each other, and the stator is in an unlocked state. Thus, when the slider 41 is fitted in the slide groove 51 to move, all the pressing plates 4 can be driven to move closer to or farther away from the accommodating chamber simultaneously. In this embodiment, when the turntable 5 rotates counterclockwise, the slider 41 moves from the first end 511 to the second end 512, and all the pressing plates 4 gradually move away from the stator, so as to unlock the pressing plates 4 from the fixing clamp. Similarly, when the turntable 5 rotates clockwise, the slide block 41 moves from the second end 512 to the first end 511, and all the pressing plates 4 gradually approach and abut against the fixing clamp, so as to realize locking of the stator.
The fixed die 2 is provided with a power member 3, and the turntable 5 is connected to the power member 3 via a link 31, and the power member 3 is preferably a motor in this embodiment. The power piece 3 is used for driving the connecting rod 31 to rotate, and the torque of the motor can be transmitted to the turntable 5 through the connecting rod 31, so that the turntable 5 is driven to rotate. Further, a screw is provided on the fixed die 2, the power member 3 is connected to the butt member 32, and the butt member 32 is screw-fitted with the screw. The position of the motor can be conveniently adjusted by using the butt joint part 32 in threaded fit with the screw rod, so that the position of the connecting rod 31 and the rotary table 5 can be adjusted to improve the torque transmission efficiency.
In addition, the fixed mold 2 is provided with a first sensor 22, and the first sensor 22 is used for detecting whether the stator is placed in the accommodating cavity, and in this embodiment, the first sensor 22 may be a photoelectric sensor, or may be any other type of sensor.
In another embodiment, the first driving member may be a cylinder or a driving member of a linear motor, and the plurality of groups of driving members synchronously move, so that the pressing plate 4 can be synchronously pushed to approach or depart from the fixed clamp, so as to shape the outer diameter of the coil of the stator.
The shaping means comprises an upper die assembly, a lower die assembly and a second driving member 9, and the locking means is capable of moving in a straight line between the upper die assembly and the lower die assembly to perform a pre-shaping of the coil in cooperation with the shaping means. The upper die assembly and the lower die assembly both comprise shaping assemblies, and the shaping assemblies comprise a base 6 and a push rod 7. The two base bodies 6 are respectively arranged on the upper die assembly and the lower die assembly. One of the seats 6 is mounted on the upper die assembly, the other seat 6 can be mounted on the lower die assembly, and of course the other seat 6 can also be mounted below the fixed die 2, in this embodiment the seat 6 is mounted below the fixed die 2.

Meanwhile, the push rod 7 is arranged on the seat body 6, so that the push rod 7 can be driven by the seat body 6 to be inserted into the stator. When the locking device moves between the upper die assembly and the lower die assembly, the second driving piece 9 drives the two base bodies 6 to move in opposite directions and continuously approaches the stator until the base bodies 6 drive the push rod 7 to be inserted into the stator, and then the power piece 3 drives the second rotary table 5 to rotate through the connecting rod 31, so that the pressing plate 4 is continuously close to the fixing clamp until the pressing plate 4 is attached to the fixing clamp by utilizing the acting force of the sliding block 41 and the sliding groove 51. At this time, the pressing plate 4 is pressed on the outside of the stator coil, and the push rod 7 is arranged in the coil, so that the coil between the pressing plate 4 and the push rod 7 can be pressed by utilizing the acting force between the pressing plate 4 and the push plate, thereby realizing the pre-shaping of the coil.

When the second driving member 9 drives the seat 6 to approach the stator, the restoring member 61 located between the seat 6 and the fixed die 2 is in a compressed state, so that the restoring member 61 disposed below the fixed die 2 can assist the seat 6 and the push rod 7 to restore, and the push rod 7 can be conveniently separated from the stator after the shaping is finished.
The lower die assembly further comprises a drogue 8, and the housing 6 is mated with a second driver 9 via the drogue 8. When the fixed die 2 is carried over the lower die assembly, the drogue 8 is positioned just under the seat 6, and the drogue 8 and the second driving member 9 are screw-engaged. The second driving member 9 is thus able to drive the drogue 8 in a vertical direction and then push the seat 6 located above it close to the stator by means of the drogue 8, thereby inserting the push rod 7 inside the stator. In this embodiment, the taper sleeve 8 is used to push the seat body 6 to move along a straight line, so that the second driving member 9 can be convenient to push the seat body 6, and meanwhile, the taper sleeve 8 can be used to limit the direction of the seat body 6 during movement, so as to improve the accuracy of the position of the seat body 6 during movement.
The machine body 1 is provided with the sliding rail 11, and meanwhile, the fixed mould 2 is provided with the sliding block 21 matched with the sliding rail 11, and the direction of the fixed mould 2 during movement is conveniently limited by utilizing the matching of the sliding rail 11 and the sliding block 21, so that the accuracy of the position of the fixed mould 2 during movement between an upper mould component and a lower mould component is ensured.
The machine body 1 is provided with a second sensor 13, and the second sensor 13 is used for detecting whether the position of the locking device is accurate when the locking device moves between the upper die assembly and the lower die assembly. In this embodiment, the second sensor 13 may be a photoelectric sensor or the like.
