Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor processing and manufacturing technology, and more specifically to a clamping and moving mechanism for stator winding installation. Background Technology
[0002] In the existing motor stator manufacturing process, the winding (i.e., stator winding) needs to be inserted into the slot formed on the inner side wall of the stator.
[0003] The existing method involves manually placing the winding machine onto its mounting frame, which then moves it backward to the shaft of the winding machine. The winding machine then embeds the stator winding into the stator. The existing mounting frame uses limit blocks with semi-circular grooves on the top and bottom to clamp and fix the winding with bolts. This requires the bolts to be removed and installed to achieve the connection, resulting in poor performance and low efficiency.
[0004] Moreover, since it is only clamped and fixed, its stator is still prone to rotation, which can cause positional displacement and affect the installation effect. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a clamping and moving mechanism for stator winding installation. It only requires flipping down the upper arc-shaped clamping block and fixing it with a quick clamp. It is convenient to assemble and disassemble the stator, and it firmly clamps and positions the stator, making the stator less prone to loosening and rotation, thus ensuring the accuracy and effect of subsequent winding.
[0006] The solution of this utility model to the aforementioned technical problem is:
[0007] A stator winding mounting clamping and moving mechanism includes a bottom movable fixing plate. A guide rail extending forward and backward is fixed to the top surface of the middle part of the bottom movable fixing plate. A support block is fixed to the rear part of the top surface of the bottom movable fixing plate. The top surface of the support block has a downwardly extending lower semi-circular arc groove in the middle part. An upper arc-shaped clamping block is movably connected to the top surface of the right side of the support block through a hinge shaft. The stator to be processed is inserted into the lower semi-circular arc groove. The lower outer side wall of the stator is close to the inner side wall of the lower semi-circular arc groove. The upper arc-shaped clamping block presses against the upper outer side wall of the stator. The horizontal extension at the left end of the upper arc-shaped clamping block presses against the top surface of the left side of the support block and is fixedly connected by a quick clamp.
[0008] A movable slider is inserted at the front of the guide rail, and the upper part of the guide rail is inserted into a groove formed in the middle of the bottom surface of the movable slider. An annular pressure block is fixed on the top surface of the movable slider, and the rear wall of the annular pressure block presses against the front end surface of the stator.
[0009] A lower support frame is provided below the bottom movable fixed plate. Fixed plates are fixed at the front and rear of the middle part of the top surface of the lower support frame. The two ends of the front and rear moving screws are movably connected to the two fixed plates through bearings. A moving motor is fixed on the rear wall of the rear fixed plate. The moving motor drives the front and rear moving screws to rotate. The moving block is screwed on the front and rear moving screws. The top surface of the moving block is fixed to the middle of the bottom surface of the bottom movable fixed plate.
[0010] Side connecting blocks are fixed on the top surfaces of the bottom movable fixing plates on both sides of the annular pressure block. The top surfaces of the side connecting blocks are movably connected to limit blocks via hinge shafts. Limit rods are fixed on the left and right sides of the front wall of the annular pressure block. The limit blocks press against the corresponding limit rods. The rear wall of the limit blocks is close to or in close contact with the front wall of the annular pressure block.
[0011] A connecting plate is fixed on the rear wall of the side connecting block, and a proximity switch is fixed on the connecting plate. The sensing end of the proximity switch corresponds to the rear wall of the corresponding limit block.
[0012] An upper connecting block is fixed to the top surface of the middle part of the upper arc-shaped clamping block. A bending limiting piece is installed on the upper connecting block. The bending limiting piece is located behind the middle part of the upper arc-shaped clamping block. The horizontal part of the bending limiting piece is inserted into the corresponding front-to-back extending upper axial slot on the outside of the stator and cooperates with the upper axial slot.
[0013] The rear vertical bending portion of the bending limiting piece is located at the upper part of the rear wall surface of the stator.
[0014] The upper connecting block has a vertical screw hole formed in the middle of the top surface of its rear part. The bottom end of the vertical screw hole is connected to and corresponds to a rectangular insertion hole formed in the middle of the bottom surface of the upper connecting block. The upper part of the lifting block is inserted into the rectangular insertion hole, and its outer side wall is in close contact with the inner side wall of the rectangular insertion hole. A vertical screw is movably connected to the middle of the top surface of the lifting block. The vertical screw is screwed into the vertical screw hole, and its top end extends out of the top surface of the upper connecting block. The bottom surface of the lifting block extends out of the bottom surface of the upper connecting block and is fixed with a bending limiting piece.
[0015] The outstanding effect of this utility model is:
[0016] It only requires flipping down the upper arc-shaped clamping block and fixing it with a quick clamp. It is easy to assemble and disassemble the stator, and it firmly clamps and positions the stator, making the stator less prone to loosening and rotation, thus ensuring the accuracy and effect of subsequent wire embedding.

The first guide rails 35 are inserted into the lower guide groove formed in the middle of the bottom surface of the corresponding bottom guide slider 191.
[0025] Furthermore, the rear of the left and right sides of the top surface of the lower support frame 300 is fixed with rear limiting blocks 36. The opposing walls of the two rear limiting blocks 36 are formed with slots 361 extending forward and backward. The outer sleeve of the horizontal guide plate 19 is inserted into the corresponding slot 361. The middle of the top surface of the rear limiting block 36 is fixed with a second proximity switch 4. The bottom end of the second proximity switch 4 is in the insertion hole formed on the top surface of the middle part of the slot 361, and its bottom end is close to the top surface of the slot 361.
[0026] Furthermore, a rear stop block 39 is fixed to the middle of the rear part of the top surface of the lower support frame 300, and the rear wall of the bottom movable fixing plate 10 faces the front wall of the rear stop block 39.
[0027] Furthermore, side connecting blocks 15 are fixed on the top surfaces of the bottom movable fixing plates 10 on both sides of the annular pressure block 13. The top surfaces of the side connecting blocks 15 are movably connected to the limiting blocks 16 through hinge shafts. Limiting rods 131 are fixed on the left and right sides of the front wall of the annular pressure block 13. The limiting blocks 16 press against the corresponding limiting rods 131. The rear wall of the limiting blocks 16 is close to or in close contact with the front wall of the annular pressure block 13.
[0028] Furthermore, a connecting plate 2 is fixed on the rear wall of the side connecting block 15, and a proximity switch 3 is fixed on the connecting plate 2. The sensing end of the proximity switch 3 corresponds to the rear wall of the corresponding limiting block 16.
[0029] Furthermore, an upper connecting block 40 is fixed to the top surface of the middle part of the upper arc-shaped clamping block 30, and a bending limiting piece 41 is installed on the upper connecting block 40. The bending limiting piece 41 is located behind the middle part of the upper arc-shaped clamping block 30, and the horizontal part of the bending limiting piece 41 is inserted into the corresponding front-to-back extending upper axial slot 101 on the outer side of the stator 100 and cooperates with the upper axial slot 101.
[0030] Furthermore, the rear vertical bending portion of the bending limiting piece 41 is located at the upper part of the rear wall surface of the stator 100.
[0031] Furthermore, a vertical screw hole 42 is formed in the middle of the top surface of the rear part of the upper connecting block 40. The bottom end of the vertical screw hole 42 communicates with and corresponds to the rectangular insertion hole 43 formed in the middle of the bottom surface of the rear part of the upper connecting block 40. The upper part of the lifting block 44 is inserted into the rectangular insertion hole 43, and its outer side wall is in close contact with the inner side wall of the rectangular insertion hole 43. A vertical screw 45 is movably connected to the middle of the top surface of the lifting block 44.

The bottom surface of the lifting block 44 extends out of the bottom surface of the upper connecting block 40 and is fixed with a bending limiting piece 41.
[0032] In this embodiment, the device is installed at the front of the winding winding equipment. First, the stator 100 is placed in the lower semi-circular arc-shaped groove 21 of the support block 20, with its rear wall pressed against the front wall of the rear stop block 39. It is necessary to ensure that the corresponding upper axial slot 101 extending forward and backward on the outer side of the stator 100 is directly above. Then, the upper arc-shaped clamping block 30 is flipped down, and a connecting part is fixed to the left side wall of the horizontal extension 31 of the upper arc-shaped clamping block 30. The hook of the quick clamp 1 is engaged with the connecting part and tightened to achieve fixation. Then, by rotating the vertical screw 45, the lifting block 44 is lowered, thus lowering the bending limit. The horizontal part of the positioning piece 41 is inserted into the corresponding upper axial slot 101 extending forward and backward on the outer side of the stator 100 and cooperates with the upper axial slot 101, thereby fixing the stator 100 in a fixed position and preventing it from rotating. Then, the annular pressure block 13 is pushed backward, pressing the rear wall surface of the annular pressure block 13 against the front end surface of the stator 100. The two limiting blocks 16 are flipped down, pressing against the corresponding limiting rod 131. The rear wall surface of the limiting block 16 is close to or in close contact with the front wall surface of the annular pressure block 13. At this time, the rear wall surface of the limiting block 16 is close to the corresponding proximity switch 3 and is sensed by it, indicating that it is installed in place.
[0033] Then, by operating the moving motor 33, the bottom moving fixed plate 10 can be moved backward, so that the outer sleeve of the horizontal guide plate 19 moves backward in the corresponding slot 361 until it is sensed by the second proximity switch 4, indicating that it has moved into place. At this time, the rear wall of the bottom moving fixed plate 10 presses against the rear stop block 39, realizing that it has moved into place. The subsequent wire embedding operation can be performed by the wire embedding device, which is an existing known device and will not be described in detail here.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
