Technical Field

[0001] The invention relates to the technical field of motor stator processing, in particular to a stator punching lamination stacking device. Background Art

[0002] The stator lamination lamination device is a device used in the production of motor stators. Its main function is to laminate the stamped stator laminations according to a specific sequence and pressing requirements. The device ensures the lamination accuracy and consistency of the stator laminations through precise pressure control and automated operation, thereby improving production efficiency and product quality. It is commonly used in the fields of motors, generators, etc.

[0003] The Chinese patent with patent announcement number CN217824663U discloses a motor stator core rapid lamination device. In view of the problem that the existing lamination device has a small application range, the following scheme is proposed, which includes a base, a hydraulic cylinder and a pressure plate. The hydraulic cylinder is located above the base, and the pressure plate is installed at the extended end of the hydraulic cylinder. The top of the base is provided with a plurality of positioning rods distributed in a circular array, and the inside of the base is provided with an adjustment mechanism for driving the horizontal movement of the plurality of positioning rods. The adjustment mechanism includes a screw rod rotatably connected to the inner wall of the bottom of the base, a disc screwed to the outside of the screw rod, a plurality of connecting rods hinged to the outside of the disc, and a plurality of sliding rods respectively hinged to the other ends of the plurality of connecting rods. This patent can lamination and process stator cores of different sizes, can adapt to the positioning holes of different stator punchings, and further improve the application range of the lamination device.

[0004] However, the current stacking device has the following problems: the positioning rod of the stacking device is not convenient for adjusting the length adaptively according to the number of stator punchings on the placement table, and when the number of stator punchings on the placement table is small, the positioning rod is likely to interfere with the downward movement trajectory of the pressure plate, resulting in inaccurate positioning of the stator punchings during the stacking process, affecting the stacking accuracy and thus affecting the stator quality. Therefore, we propose a stator punching stacking device. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a stator punching lamination stacking device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a stator punching lamination device, including a device body, a lamination assembly is arranged on the top of the device body, a placement table is fixed inside the device body, a positioning device is passed through the top of the placement table, the positioning device includes an electric push rod, the fixed end of the electric push rod is fixed to the bottom of the device body, the telescopic end of the electric push rod is hinged with three hinged rods, the three hinged rods are hinged with slides on one side away from the electric push rod, the three slides are slidably installed on the bottom of the placement table, the tops of the three slides are passed through and slidably installed with T-shaped rods, and A spring is provided between the T-shaped rod and the bottom of the slide plate, and a strip groove for the T-shaped rod to slide is provided on the top of the placement table. The telescopic end of the electric push rod pulls the hinged rod to drive the slide plate to move toward the center of the placement table, and the slide plate drives the T-shaped rod to move accordingly, so that the T-shaped rod positions the stator punching sheet placed on the placement table, thereby ensuring that the stator punching sheet is located below the pressure plate of the stacking assembly. When the height of the number of stator punching sheets placed on the placement table is less than the height of the T-shaped rod, at this time, when the pressure plate of the stacking assembly moves downward to stack the stator punching sheets, the pressure plate of the stacking assembly first pushes the top of the T-shaped rod to drive the T-shaped rod to move downward.

[0007] The cam is secured to the upper and lower portions of the T-bar by means of an L-shaped lever, the L-shaped lever being secured to the upper and lower portions of the T-bar by means of a spring. The bottom of the pressure plate of the pressing assembly is provided with a receiving groove that is compatible with the pressure rod. When the T-shaped rod approaches the stator punching sheet, the T-shaped rod will drive the L-shaped rod to approach the stator punching sheet through the insertion rod. After the L-shaped rod is close to the stator punching sheet, the T-shaped rod will move toward the stator punching sheet. At this time, under the action of the friction force between the cross support rod of the L-shaped rod and the friction wheel, the cross support rod of the L-shaped rod drives the friction wheel to rotate, and the friction wheel drives the pressure rod to swing toward the center of the placement table until the pressure rod enters the receiving groove of the T-shaped rod, and then when the pressure plate of the stacking assembly is downward, the receiving groove of the pressure plate of the stacking assembly will overlap with the pressure rod, and the pressure plate of the stacking assembly pushes the pressure rod to apply pressure on the top of the stator punching sheet.

[0008] According to the above technical solution, a correction device is provided in the middle of the placing table, and the correction device includes a motor, which is fixed to the bottom of the placing table through a bracket, and the output end of the motor passes through the bottom of the placing table, and a turntable is fixed at the top outer wall of the output end of the motor, and three elastic telescopic rods 1 are fixed to the outside of the turntable, and an elastic telescopic rod 2 is fixed to the top of the end of the three elastic telescopic rods 1 away from the turntable, and a U-shaped plate 1 is fixed to the top of the elastic telescopic rod 2, and the top of the U-shaped plate 1 is an inclined surface that decreases from the center of the placing table toward the direction away from the center of the placing table. Under the elastic force of the elastic telescopic rod 1, the elastic telescopic rod 1 drives the U-shaped plate 1 to be close to the inner wall of the groove of the stator punching sheet through the elastic telescopic rod 2, and the turntable is driven to rotate by the motor, and the turntable drives the U-shaped plate 1 to rotate through the elastic telescopic rod 1 and the elastic telescopic rod 2.

[0009] According to the above technical scheme, the correction device also includes a triangular gear ring and three elastic retractable plates. The triangular gear ring is embedded in the lower outer wall of the turntable, and the fixed ends of the three elastic retractable plates are respectively fixed on the tops of the three slides, and the tops of the fixed ends of the elastic retractable plates are in the same plane as the top of the placing table. The retractable ends of the elastic retractable plates are arranged in the direction of the triangular gear ring, and the retractable ends of the elastic retractable plates are arranged in a triangular shape. The tooth grooves of the triangular gear ring are located on the movement trajectory of the retractable ends of the elastic retractable plates. At the same time, when the T-shaped rod approaches the stator punching sheet, the T-shaped rod drives the elastic retractable plate to move with it, and the fixed ends of the elastic retractable plates will form a support surface for the stator punching sheet at the strip grooves of the placing table, thereby providing a stable contact point to help the stator punching sheet maintain a stable position, avoiding the existence of the strip grooves of the placing table, which causes the stator punching sheet to warp or shift during the stacking process. At the same time, the triangular shape of the retractable end of the elastic retractable plate will be inserted into the tooth grooves of the triangular gear ring, and the triangular gear ring limits the position of the turntable.

[0010] According to the above technical scheme, a stabilizing device is provided at the turntable, and the stabilizing device includes a three-way box, three L-shaped plug rods, three air pipes, three arc shells, three arc plug rods, six arc rods, three U-shaped plates 2, three L-shaped connecting rods, and three slide groove plates. The three-way box is fixed to the bottom of the placement table, and the three-way box is sleeved on the outside of the output end of the motor. One ends of the three L-shaped plug rods are respectively slidably installed on the inner wall of the through-port of the three-way box, and the other ends of the three L-shaped plug rods are respectively fixed to the bottom of the fixed end of the elastic telescopic plate, and the circumference of the three arc shells is evenly fixed on the top of the turntable, and the three air pipes are respectively fixed between the three arc shells and the outer wall of the output end of the motor, one ends of the three arc plug rods are respectively slidably installed in the inside of the three arc shells, and the three slide groove plates are respectively fixed on the other ends of the three arc plug rods. The three L-shaped connecting rods are respectively slidably installed on the top of the three slide groove plates. The six arc rods are respectively fixed on the outer wall of the U-shaped plate one, and the three U-shaped plates two are respectively slidably installed between the outsides of two adjacent arc rods, and the side surfaces of the three U-shaped plates two are respectively slidably installed vertically on the outsides of the three L-shaped connecting rods. The output end of the motor is a cavity structure setting, and the interior of the three-way box is connected with the interior of the arc shell through the cavity and the air pipe at the output end of the motor. When the T-shaped rod drives the elastic telescopic plate to move, the fixed end of the elastic telescopic plate drives the L-shaped plug rod to move with it, and the L-shaped plug rod will squeeze the air in the three-way box, and the air in the three-way box is transmitted to the inside of the arc shell through the cavity and the air pipe at the output end of the motor. The air entering the arc shell will push the arc plug rod to drive the slide plate to rotate in the direction away from the arc shell, and the slide plate drives the U-shaped plate two to move along the outside of the arc rod in the direction away from the U-shaped plate one through the L-shaped connecting rod, and the U-shaped plate two contacts with the inner wall on the other side of the stator punching sheet.

[0011] The present invention provides a stator punching lamination lamination device, which has the following beneficial effects:

[0012] (1) The present invention arranges a positioning device so that the electric push rod, the articulated rod, the slide plate, the placement table, and the T-shaped rod cooperate. When the height of the number of stator punching sheets placed on the placement table is less than the height of the T-shaped rod, the T-shaped rod will not interfere with the downward movement trajectory of the pressure plate of the lamination assembly after positioning the stator punching sheets, thereby facilitating the lamination operation of the stator punching sheets when the number of stator punching sheets on the placement table is small; at the same time, the T-shaped rod, the insertion rod, the L-shaped rod, the friction wheel, and the lamination assembly cooperate to push the pressure rod to apply pressure on the top of the stator punching sheet, thereby ensuring that the stator punching sheet remains stable under the clamping and positioning action of the T-shaped rod, preventing the stator punching sheet from slight movement or deflection, and ensuring that it does not deviate from the predetermined position during the processing, thereby maintaining high-precision positioning.

[0013] (2) The present invention sets a deviation correction device so that the elastic telescopic rod 1, the elastic telescopic rod 2, the U-shaped plate 1, the motor and the turntable cooperate to adjust the contact state between the U-shaped plate 1 and the elastic telescopic rod 2 and the stator punching sheet. If the stator punching sheet deviates, the U-shaped plate 1 can timely adjust the position of the stator punching sheet to help the stator punching sheet to realign, thereby correcting the deviation and restoring the stator punching sheet to the correct position, thereby avoiding the problem of subsequent processing errors caused by the deviation of the stator punching sheet; at the same time, the T-shaped rod drives the fixed end of the elastic telescopic plate to form a support surface for the stator punching sheet at the strip groove of the placement table, thereby providing a stable connection. The contacts help the stator punching sheets to maintain a stable position, avoiding the existence of the placement table strip groove, which may cause the stator punching sheets to warp or shift during the stacking process. At the same time, the triangular end of the elastic telescopic plate will be inserted into the tooth groove of the triangular gear ring. The triangular gear ring limits the position of the turntable, so that the turntable indirectly limits the position of the stator punching sheets through the U-shaped plate one and the elastic telescopic rod two. This limiting effect ensures that the stator punching sheets always remain in the correct position during the stacking process, especially during the stacking process, the stator punching sheets will not be displaced or rotated unnecessarily due to external force or vibration.

[0014] (3) The present invention arranges a stabilizing device so that the T-shaped rod, elastic telescopic plate, L-shaped plug rod, three-way box, motor, air pipe, arc shell, arc plug rod, slide plate, and L-shaped connecting rod cooperate to drive U-shaped plate 2 to contact the inner wall of the other side of the stator punching sheet. U-shaped plate 1 and U-shaped plate 2 respectively support the two sides of the groove of the stator punching sheet, so that U-shaped plate 2 and U-shaped plate 1 form a stable supporting structure, which helps the stator punching sheet to remain flat and reduce internal stress concentration, thereby reducing the risk of deformation during the stacking process of the stator punching sheet.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1 - Fig.10 One embodiment of the present invention is: a stator punching lamination device, comprising a device body 1, a lamination assembly 3 is arranged on the top of the device body 1, a placement table 2 is fixed inside the device body 1, a positioning device 4 is passed through the placement table 2, the positioning device 4 comprises an electric push rod 41, the fixed end of the electric push rod 41 is fixed to the bottom of the device body 1, the telescopic end of the electric push rod 41 is hinged with three hinged rods 42, the three hinged rods 42 are hinged with slide plates 43 on one side away from the electric push rod 41, the three slide plates 43 are slidably installed on the bottom of the placement table 2, and the three slide plates 43 A T-shaped rod 44 is penetrated and slidably installed on the top, and a spring is provided between the T-shaped rod 44 and the bottom of the slide plate 43. A strip groove for the sliding of the T-shaped rod 44 is opened on the top of the placement table 2. Through the setting of the above structure, the telescopic end of the electric push rod 41 moves downward, and the telescopic end of the electric push rod 41 pulls the hinge rod 42 to drive the slide plate 43 to move toward the center of the placement table 2. The slide plate 43 drives the T-shaped rod 44 to move with it, so that the T-shaped rod 44 positions the stator punching placed on the placement table 2, thereby ensuring that the stator punching is located below the pressure plate of the stacking assembly 3.

[0028] A plug rod 45 is penetrated and slidably installed on the side of the T-shaped rod 44 away from the center of the placement table 2, and a spring is provided between the plug rod 45 and the outer wall of the T-shaped rod 44, an L-shaped rod 46 is fixed on the side of the plug rod 45 close to the center of the placement table 2, and the cross support rod of the L-shaped rod 46 horizontally penetrates the T-shaped rod 44, and a friction wheel 48 is rotatably installed on the top of the side of the T-shaped rod 44 away from the center of the placement table 2 through a bracket, and a pressure rod 47 is fixed to the outside of the rotating shaft of the friction wheel 48, the outer wall of the friction wheel 48 is set as a rough surface, and the top of the cross support rod of the L-shaped rod 46 is set as a rough surface. The outer portion of 8 is in contact with the top of the horizontal support rod of the L-shaped rod 46, the top of the T-shaped rod 44 is provided with a receiving groove for accommodating the pressure rod 47, and the bottom of the pressure plate of the stacking assembly 3 is provided with a receiving groove adapted to the pressure rod 47. Through the arrangement of the above-mentioned structure, the pressure plate of the stacking assembly 3 pushes the pressure rod 47 to apply pressure on the top of the stator punching sheet, thereby ensuring that the stator punching sheet remains stable under the clamping and positioning action of the T-shaped rod 44, preventing the stator punching sheet from slight movement or deflection, and ensuring that it will not deviate from the predetermined position during the processing, thereby maintaining high-precision positioning.

[0029] A deviation correction device 5 is provided in the middle of the placement table 2. The deviation correction device 5 includes a motor 51. The motor 51 is fixed to the bottom of the placement table 2 through a bracket, and the output end of the motor 51 passes through the bottom of the placement table 2. A turntable 52 is fixed to the outer wall of the top of the output end of the motor 51. Three elastic telescopic rods 1 53 are fixed to the outside of the turntable 52. An elastic telescopic rod 2 54 is fixed to the top of the end of the three elastic telescopic rods 1 53 away from the turntable 52. A U-shaped plate 1 55 is fixed to the top of the elastic telescopic rod 2 54. The top of the U-shaped plate 1 55 is from the center of the placement table 2 to away from the placement table 2. The inclined surface is set in a decreasing direction towards the center. Through the setting of the above structure, the contact state between the U-shaped plate 55 and the elastic telescopic rod 2 54 and the stator punching sheet is adjusted. If the stator punching sheet is offset, the U-shaped plate 55 can adjust the position of the stator punching sheet in time to help the stator punching sheet to be realigned, thereby correcting the deviation and restoring the stator punching sheet to the correct position, avoiding the problem of subsequent processing errors caused by the offset of the stator punching sheet. It is worth mentioning that the inclined surface of the U-shaped plate 55 will guide the stator punching sheet, thereby facilitating the stator punching sheet to be sleeved on the outside of the three U-shaped plates 55.

[0030] The deviation correction device 5 also includes a triangular gear ring 56 and three elastic telescopic plates 57. The triangular gear ring 56 is embedded in the lower outer wall of the turntable 52. The fixed ends of the three elastic telescopic plates 57 are respectively fixed to the tops of the three slide plates 43, and the tops of the fixed ends of the elastic telescopic plates 57 are in the same plane as the top of the placement table 2. The telescopic ends of the elastic telescopic plates 57 are arranged in the direction of the triangular gear ring 56. The telescopic ends of the elastic telescopic plates 57 are arranged in a triangular shape. The tooth grooves of the triangular gear ring 56 are located on the movement trajectory of the telescopic ends of the elastic telescopic plates 57. Through the arrangement of the above structure, the fixed ends of the elastic telescopic plates 57 will form a support surface for the stator punching sheets at the strip grooves of the placement table 2, thereby providing A stable contact point is formed to help the stator punching sheet maintain a stable position, avoiding the existence of the strip groove of the placement table 2, which may cause the stator punching sheet to warp or shift during the stacking process. At the same time, the triangular end of the elastic telescopic plate 57 will be inserted into the tooth groove of the triangular gear ring 56. The triangular gear ring 56 limits the position of the turntable 52, so that the turntable 52 indirectly limits the position of the stator punching sheet through the U-shaped plate 1 55 and the elastic telescopic rod 2 54. This limiting effect ensures that the stator punching sheet always remains in the correct position during the stacking process, especially in the stacking process, the stator punching sheet will not be displaced or rotated unnecessarily due to external force or vibration.

[0031] When in use, the stator punching sheets to be stacked are placed on the placement table 2, and the stator punching sheets are sleeved on the outside of the three U-shaped plates 55, and the three U-shaped plates 55 are placed in the inner grooves of the stator punching sheets. Under the elastic force of the elastic telescopic rod 1 53, the elastic telescopic rod 1 53 drives the U-shaped plate 1 55 to cling to the inner wall of the groove of the stator punching sheets through the elastic telescopic rod 2 54. The elastic telescopic rod 2 54 here also clings to the inner wall of the groove of the stator punching sheets. The turntable 52 is driven to rotate by the motor 51. The turntable 52 is driven by the elastic telescopic rod 1 53 and the elastic telescopic rod 2 54. The movable U-shaped plate 55 rotates, thereby adjusting the contact state between the U-shaped plate 55 and the elastic telescopic rod 2 54 and the stator punching sheet. If the stator punching sheet deviates, the U-shaped plate 55 can timely adjust the position of the stator punching sheet to help the stator punching sheet realign, thereby correcting the deviation and restoring the stator punching sheet to the correct position, avoiding the problem of subsequent processing errors caused by the deviation of the stator punching sheet, and then stopping the motor 51. It is worth noting that the inclined surface of the U-shaped plate 55 guides the stator punching sheet, thereby facilitating the stator punching sheet to be sleeved on the outside of the three U-shaped plates 55;

[0032] Start the electric push rod 41, the telescopic end of the electric push rod 41 moves downward, the telescopic end of the electric push rod 41 pulls the hinged rod 42 to drive the slide plate 43 to move toward the center of the placement table 2, and the slide plate 43 drives the T-shaped rod 44 to move, so that the T-shaped rod 44 positions the stator punching placed on the placement table 2, thereby ensuring that the stator punching is located below the pressure plate of the stacking assembly 3. When the T-shaped rod 44 approaches the stator punching, the T-shaped rod 44 will drive the L-shaped rod 46 to approach the stator punching through the insertion rod 45. After the L-shaped rod 46 is close to the stator punching, the T-shaped rod 44 will continue to move in the direction close to the stator punching. At this time, under the friction force between the cross support rod of the L-shaped rod 46 and the friction wheel 48, the cross support rod of the L-shaped rod 46 drives the friction wheel 48 to rotate, and the friction wheel 48 drives the pressure rod 47 to swing toward the center of the placement table 2 until the pressure rod 47 enters the accommodating groove of the T-shaped rod 44. At the same time, when the T-shaped rod 44 approaches the stator punching sheet, the T-shaped rod 44 drives the elastic telescopic plate 57 to move with it, and the fixed end of the elastic telescopic plate 57 will form a support surface for the stator punching sheet at the strip groove of the placement table 2, thereby providing a stable contact point to help the stator punching sheet maintain a stable position, avoiding the existence of the strip groove of the placement table 2, which may cause the stator punching sheet to warp or shift during the stacking process. At the same time, the triangular telescopic end of the elastic telescopic plate 57 will be inserted into the tooth groove of the triangular gear ring 56, and the triangular gear ring 56 limits the position of the turntable 52, so that the turntable 52 indirectly limits the position of the stator punching sheet through the U-shaped plate 1 55 and the elastic telescopic rod 2 54. This limiting effect ensures that the stator punching sheet always remains in the correct position during the stacking process, especially during the stacking process, the stator punching sheet will not be displaced or rotated unnecessarily due to external force or vibration.

[0033] Then, the stacking assembly 3 is started, and the pressure plate of the stacking assembly 3 moves downward to stack the stator punching sheets on the placement table 2. During this process, the receiving groove of the pressure plate of the stacking assembly 3 will overlap with the pressure rod 47, and the pressure plate of the stacking assembly 3 pushes the pressure rod 47 to apply pressure on the top of the stator punching sheets, thereby ensuring that the stator punching sheets remain stable under the clamping and positioning action of the T-bar 44, preventing the stator punching sheets from slight movement or deflection, and ensuring that they will not deviate from the predetermined position during the processing, thereby maintaining high-precision positioning.

[0034] It should also be noted that when the height of the number of stator punchings placed on the placement table 2 is less than the height of the T-bar 44, at this time, when the pressure plate of the stacking assembly 3 moves downward to stack the stator punchings, the pressure plate of the stacking assembly 3 first pushes the top of the T-bar 44 to drive the T-bar 44 to move downward, and the spring corresponding to the T-bar 44 is stretched, so that the T-bar 44 will not interfere with the downward movement trajectory of the pressure plate of the stacking assembly 3 after positioning the stator punching, thereby facilitating the stacking operation of the stator punchings when the number of stator punchings on the placement table 2 is small.

[0035] See also Figure 1 - Fig.10 On the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device 6 is provided at the turntable 52 .

[0036] The stabilizing device 6 includes a three-way box 61, three L-shaped plug rods 62, three air pipes 63, three arc shells 64, three arc plug rods 65, six arc rods 66, three U-shaped plates 67, three L-shaped connecting rods 68, and three slide groove plates 69. The three-way box 61 is fixed to the bottom of the placement table 2, and the three-way box 61 is sleeved on the outside of the output end of the motor 51. One ends of the three L-shaped plug rods 62 are respectively slidably installed on the inner wall of the through-port of the three-way box 61, and the other ends of the three L-shaped plug rods 62 are respectively fixed to the bottom of the fixed end of the elastic telescopic plate 57. The three arc shells 64 are uniformly fixed on the top of the turntable 52. The three air pipes 63 are respectively fixed between the three arc shells 64 and the outer wall of the output end of the motor 51. One ends of the three arc plug rods 65 are respectively slidably installed in the inside of the three arc shells 64. The three slide groove plates 69 are respectively fixed to the other ends of the three arc plug rods 65. 68 are respectively slidably installed on the top of the three slide plates 69, the six arc rods 66 are respectively fixed on the outer walls of the U-shaped plate 1 55, the three U-shaped plates 2 67 are respectively slidably installed between the outsides of two adjacent arc rods 66, and the sides of the three U-shaped plates 2 67 are respectively vertically slidably installed on the outsides of the three L-shaped connecting rods 68, the output end of the motor 51 is set as a cavity structure, the interior of the three-way box 61 is connected with the interior of the arc shell 64 through the cavity at the output end of the motor 51 and the air pipe 63, through the setting of the above structure, the U-shaped plate 2 67 is in contact with the inner wall of the other side of the stator punching sheet, the U-shaped plate 1 55 and the U-shaped plate 2 67 respectively support the two sides of the groove of the stator punching sheet, so that the U-shaped plate 2 67 and the U-shaped plate 1 55 form a stable support structure, which helps the stator punching sheet to remain flat and reduce internal stress concentration, thereby reducing the risk of deformation during the stacking process of the stator punching sheet.

[0037] When in use, when the T-shaped rod 44 drives the elastic expansion plate 57 to move, the fixed end of the elastic expansion plate 57 drives the L-shaped plug rod 62 to move along, and the L-shaped plug rod 62 squeezes the air in the three-way box 61. The air in the three-way box 61 is transmitted to the inside of the arc shell 64 through the cavity at the output end of the motor 51 and the air pipe 63. The air entering the arc shell 64 pushes the arc plug rod 65 to drive the slide plate 69 to rotate in the direction away from the arc shell 64. The slide plate 69 drives the U-shaped plate 2 67 to move along the outside of the arc rod 66 in the direction away from the U-shaped plate 1 55 through the L-shaped connecting rod 68. When the U-shaped plate 1 55 moves, the U-shaped plate 2 67 contacts the inner wall of the other side of the stator punching sheet, and the U-shaped plate 1 55 and the U-shaped plate 2 67 respectively support the two sides of the groove of the stator punching sheet, so that the U-shaped plate 2 67 and the U-shaped plate 1 55 form a stable supporting structure, which helps the stator punching sheet to remain flat and reduces internal stress concentration, thereby reducing the risk of deformation during the lamination process of the stator punching sheet. It is worth noting that when the U-shaped plate 1 55 moves downward, the U-shaped plate 1 55 will drive the U-shaped plate 2 67 to move downward through the arc rod 66, and the U-shaped plate 2 67 slides downward along the outside of the L-shaped connecting rod 68.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
