Description

Technical Field

[0001] The utility model relates to a stator shaping device, belonging to the field of stator shaping equipment. Background Art

[0002] Stator shaping is a processing technology, usually used for the stator part of motors and generators. The stator is a fixed part in the motor, which contains stator windings and stator cores. The purpose of stator shaping is to make the stator better cooperate with other components through processing and shape design, so as to improve the efficiency and performance of the motor.

[0003] In the prior art, the stator winding needs to be embedded in the groove of the stator core for assembly to form a stator. Since some stator windings are prone to protrusion and are not completely embedded in the groove of the stator core, a shaping device is required to shape the inside of the stator so that the stator winding and the stator core are completely embedded. During the shaping process, it is necessary to apply extrusion pressure to the protruding stator winding to squeeze the winding into the core groove. Since the size of the extrusion die is fixed, the contact area of ​​the inner ring surface of the stator of different sizes is different, which easily leads to a blind spot that cannot be contacted, resulting in the stator winding in some positions unable to be squeezed into the groove of the stator core, thereby reducing the stator shaping processing quality.

[0004] In summary, the present invention provides a stator shaping device to solve the above problems. Utility Model Content

[0024] See also Figure 2-4The inner support shaping structure 7 includes a chassis 71 and a mounting tube 72. The mounting tube 72 is rotatably connected to the top of the mounting plate 3 and is located between the two clamps 6. The chassis 71 is fixedly connected to the bottom of the mounting plate 3 and is located directly below the mounting tube 72. The top of the mounting tube 72 is rotatably connected to a cover plate 73. A motor 74 is fixedly connected to the inside of the chassis 71. The motor 74 is connected to an external power supply and is provided with a power control switch. The output end of the motor 74 is fixedly connected to a drive shaft 75. One end of the drive shaft 75 passes through the chassis 71 in sequence. , mounting plate 3 and mounting cylinder 72 and extend to the bottom of cover plate 73, the axial surface of driving shaft 75 and the interior of mounting cylinder 72 are sleeved with connecting sleeve 76, the top and bottom of one side of connecting sleeve 76 are fixedly connected with electric push rods 77, the output ends of two electric push rods 77 pass through one side of the inner wall of mounting cylinder 72 and extend to the outside of mounting cylinder 72, an arc push plate 78 is fixedly connected between the output ends of two electric push rods 77, two electric push rods 77 are connected with external power supply and are provided with the same power control switch.

[0025] See also Figure 2-4 The four sides of the axial surface of the drive shaft 75 located inside the mounting cylinder 72 are all rectangular convex strips. The drive shaft 75 is fixedly embedded with the connecting sleeve 76 through four rectangular convex strips. The top and bottom ends of the mounting cylinder 72 are both open. The inner concave arc surface of the arc push plate 78 is parallel to the outer cylinder surface of the mounting cylinder 72, and the outer convex arc surface of the arc push plate 78 is parallel to the inner concave arc surface of a clamp 6. The mounting cylinder 72 can stably support the two electric push rods 77 without affecting the rotation of the two electric push rods 77. The two electric push rods 77 are in contact with the mounting cylinder 72. The drive shaft 75 is rotatably connected to the chassis 71. The position of the arc push plate 78 can be adjusted through the two electric push rods 77, so that it can be appropriately adjusted according to the inner diameter of the stator to be shaped. The drive shaft 75 is rotatably connected to the mounting plate 3, and the drive shaft 75 One end of the cover plate 73 is rotatably connected to the bottom of the cover plate 73. When the drive shaft 75 rotates, the connecting sleeve 76 can be driven to rotate. The connecting sleeve 76 drives the two electric push rods 77 to rotate and drives the mounting tube 72 to rotate at the same time, so that the unshaped stator sleeve is arranged on the outside of the mounting tube 72 and is located on the top of the mounting plate 3, so that the arc push plate 78 is located inside the stator, and then the two electric push rods 77 are started to push the arc push plate 78 to move, so that the outer convex arc surface of the arc push plate 78 contacts the inner wall of the stator. When the electric push rod 77 rotates, it drives the arc push plate 78 to revolve in contact with the inner ring surface of the stator. When the arc push plate 78 passes through the protruding inner winding inside the stator, the inner winding can be squeezed into the groove of the inner ring surface of the stator through the extrusion force when the arc push plate 78 rotates and passes, thereby completing the stator shaping work.

[0026] Specific implementation method: The unshaped stator is sleeved on the outside of the inner support shaping structure 7 and placed on the top of the mounting plate 3. At this time, the stator is located between the two clamps 6. Then the hydraulic cylinders 5 on the opposite sides of the two fixing plates 4 are started to push the two clamps 6 to shorten the distance between them, so that the stator placed between the two clamps 6 and sleeved on the outside of the inner support shaping structure 7 can be clamped and fixed.

[0027] Start the two electric push rods 77 inside the inner support shaping structure 7 to push the arc-shaped push plate 78 to move, so that the outer convex arc surface of the arc-shaped push plate 78 contacts the inner wall of the stator, and then start the motor 74 to drive the drive shaft 75 to rotate. When the drive shaft 75 rotates, it can drive the connecting sleeve 76 to rotate. The connecting sleeve 76 drives the two electric push rods 77 to rotate and drives the installation cylinder 72 to rotate at the same time. When the electric push rod 77 rotates, it drives the arc-shaped push plate 78 to revolve around the inner ring surface of the stator. When the arc-shaped outer convex surface of the arc-shaped push plate 78 passes through the protruding inner winding inside the stator, the inner winding can be squeezed into the groove of the inner ring surface of the stator by the extrusion force of the arc-shaped push plate 78 when it rotates, thereby completing the stator shaping work. The outer arc surface of the arc-shaped push plate 78 can reduce the resistance between it and the inner winding of the stator, avoid the phenomenon of squeezing, bending and deforming the inner winding, and effectively improve the stator shaping processing quality.

[0028] The position of the arc-shaped push plate 78 can be adjusted by two electric push rods 77, so that it can be appropriately adjusted according to the inner diameter of the stator to be shaped, effectively improving the adaptability of the stator shaping device.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
