Description

Technical Field

[0001] The invention relates to the technical field of stator cores, in particular to a stator core lamination device for motor production. Background Art

[0002] The stator core is an important component of the motor magnetic circuit. The stator core is composed of multiple stator punchings stacked together and fixed by riveting or welding. The multiple stator punchings need to be stacked by a stacking device.

[0003] For example, a stator core lamination device for motor production with announcement number CN216959608U first turns the hand wheel to drive the screw to rotate. The screw with a threaded groove and the fixing nut can make the screw extend to the left or right. A ball bearing is installed on the other end of the screw, and the ball bearing is fixed to the slide rail. Then the screw can rotate relative to the slide rail, and drive the slide rail to move left and right at the same time, so that the two clamps can be brought close to each other to clamp the stator core. However, in actual use, multiple stator punchings need to be stacked and placed before laminating the stator core. During the process, multiple slots are usually set inside the stator punching sheets. When the stator punching sheets are stacked, it is necessary to ensure that the slots of the stator punching sheets are aligned, so as to facilitate the subsequent placement of insulating paper and threading inside the slots. When the stator punching sheets are stacked, multiple plug rods are usually placed inside the slots, so as to ensure that the slots on the stacked stator punching sheets are aligned during the subsequent stacking process. However, when stator punching sheets of different sizes are stacked, the slots on the stator punching sheets of different sizes are of different sizes, and thus plug rods of different diameters are mainly replaced, which is inconvenient when limiting the stacking of the stator punching sheets, and there are certain defects in use.

[0004] Therefore, we propose a stator core lamination device for motor production to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a stator core stacking device for motor production, so as to solve the problem proposed in the above-mentioned background technology that multiple stator punching sheets need to be stacked and placed before stacking the stator core, and multiple slots are usually arranged inside the stator punching sheets during the placement process. When the stator punching sheets are stacked, it is necessary to ensure that the slots of the stator punching sheets are aligned, so as to facilitate the subsequent placement of insulating paper and threading inside the slots. When the stator punching sheets are stacked, multiple plug rods are usually placed inside the slots, so as to ensure that the slots on the stacked stator punching sheets are aligned during the subsequent stacking process. However, when stator punching sheets of different sizes are stacked, the slots on the stator punching sheets of different sizes are of different sizes, and thus it is mainly necessary to replace plug rods of different diameters, which makes it inconvenient to limit the stacking of the stator punching sheets.

[0027] By adopting the above technical solution, it can be avoided that the X-shaped plate and the two groups of moving rods conflict with the vertical rod and the rubber sleeve when the stator core is pressed down.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: the stator core lamination equipment for motor production is provided with positioning components at the top and bottom of the placement plate, so that when a plurality of stator punching sheets are abutted, the stator punching sheets can be positioned, and the slots between the plurality of stator punching sheets can be aligned after being stacked, so as to avoid affecting the stacking quality of the stator punching sheets, and stator punching sheets of different sizes can be positioned, thereby improving the scope of application and practicality;

[0029] 1. Positioning components are set at the top and bottom of the placement plate. Before stacking the stator cores, multiple stator cores need to be stacked. First, a small number of stator cores can be stacked on the top of the placement plate so that the two groups of rubber sleeves are located in the slots of the positioning punching sheets. When in use, lubricating products can be applied to the outside of the two groups of rubber sleeves. After stacking a small number of stator punching sheets, the slots of a small number of stator punching sheets cannot be aligned. At this time, the reduction motor is started to drive the turntable to rotate. After the turntable rotates, the two groups of column rods can be pushed away from each other through the sliding connection between the through groove and the column rod. After the column rod moves, it drives the rubber sleeve to move, so that the rubber sleeve moves to the inside of the slot of the stator punching sheet to fit the slot, and the column rod drives the positioning rod to slide on the positioning block during the movement to limit the position. After the positioning rod on one side moves, it can move the cylinder body by abutting against the cylinder body, and the cylinder body slides on the outside of the piston. The air inside the cylinder can be compressed by the movement, and the air inside the cylinder can be pushed into the connecting pipe. Then the air enters the rubber sleeve through the connecting pipe, so that the rubber sleeve can expand. During the expansion of the rubber sleeve, the support bar is driven to move, so that the movable rod slides inside the movable groove, thereby avoiding the support bar from bending significantly, and avoiding the stator punching from being difficult to be sleeved on the outside of the rubber sleeve during the subsequent stacking of the stator punchings, thereby making the rubber sleeve and the slot on the stator punching fully fit, so that the stator punching can be positioned, and the inflation amount of the rubber sleeve is proportional to the size of the stator punching. The positioning component allows the stator punching to be positioned when a plurality of stator punchings are abutted, so that the slots between the plurality of stator punchings can be aligned after being stacked, so as to avoid affecting the stacking quality of the stator punchings, and stator punchings of different sizes can be positioned, thereby improving the scope of application and practicality.

[0030] 2. After the stator punching sheets are stacked, two electric cylinders can be started to drive the rubber plates to move. The rubber plates can fit the outside of the stator core through their own soft material, and the rubber plates drive the limit rods to slide on the fixed frame to limit the position during the movement, so that the stator core can be fixed. Then, the stator core is pressed down by the pressing assembly. After the stator core is stacked, the turntable can be rotated in the opposite direction, so that the positioning punching sheets are no longer positioned. The movable frame is driven to move by the electric push rod. During the movement of the movable frame, the support rods are driven to slide on the workbench to limit the position, so that the two sets of rubber plates leave the stator core. Then, a support plate can be set under the stator core, and the fixed assembly no longer fixes the stator core. The stator core can be taken out by moving the support plate, so that the positioning assembly can leave the stator core, which is convenient for removing the stator core and improves practicality.

[0031] 3. When fixing the stator core, the movement of the rubber plate contacts the ball on the moving rod, the rubber plate continues to move, and the ball rotates on the rubber plate, so that the moving rod slides inside the rectangular groove, and the L-shaped rod slides on the fixed block and stretches the telescopic spring, so that when fixing stator cores of different sizes, the moving rod can move with the movement of the rubber plate, and the overall size of the two groups of moving rods can be adjusted. When stacking the stator core, the hydraulic push rod drives the X-shaped plate to move downward, and the ball rotates on the rubber plate. The stator core can be stacked through the X-shaped plate and the two groups of moving rods, and when stacking stator cores of different sizes, there is no need to replace the pressing plate, thereby improving practicality.

The bottom of the placement plate 107 is located on both sides of the two sets of sliding grooves 201 and the positioning blocks 209 are symmetrically mounted thereon. The positioning rods 208 are slidably connected to the positioning blocks 209.

[0052] One side positioning rod 208 is in contact with the cylinder 213, and a connecting pipe 215 is connected through the lower side of the cylinder 213 close to the positioning rod 208, and one end of the connecting pipe 215 away from the cylinder 213 is connected through the rubber sleeve 204;

[0053] A reduction motor 216 is fixedly installed at the inner bottom of the movable frame 105, and a turntable 217 is fixedly installed at the output end of the reduction motor 216.

[0054] Embodiment 1: Figure 1-Figure 8 and Fig.11As shown, a positioning assembly 2 is provided at the top and bottom of the placement plate 107. Before the stator cores are stacked, a plurality of stator cores need to be stacked. First, a small number of stator cores can be stacked on the top of the placement plate 107 so that the two groups of rubber sleeves 204 are located in the slots of the positioning punching sheets. When in use, a lubricating product can be applied to the outside of the two groups of rubber sleeves 204. After a small number of stator punching sheets are stacked, the slots of a small number of stator punching sheets cannot be aligned. At this time, the reduction motor 216 is started to drive the turntable 217 to rotate. After the turntable 217 rotates, the two groups of column rods 202 can be pushed away from each other through the sliding connection between the through slot 218 and the column rod 202. After the column rod 202 moves, it drives the rubber sleeve 204 to move, so that the rubber sleeve 204 moves to the inside of the slot of the stator punching sheet to fit the slot, and the column rod 202 drives the positioning rod 208 to slide on the positioning block 209 to limit the position during the movement. After the positioning rod 208 on one side moves, it can push the cylinder 213 to move by abutting against the cylinder 213. The cylinder 213 is The outside of the piston 212 slides, so that the air inside the cylinder 213 can be compressed, and the air inside the cylinder 213 can be pushed into the connecting pipe 215.

During the expansion of the rubber sleeve 204, the support bar 207 is driven to move, so that the movable rod 206 slides inside the movable groove 205, thereby preventing the support bar 207 from bending significantly, and preventing the stator punching from being difficult to fit during the subsequent stator punching stacking process. On the outside of the rubber sleeve 204, the rubber sleeve 204 can be fully fitted with the slot on the stator punching sheet, the stator punching sheet can be positioned, and the inflation amount of the rubber sleeve 204 is proportional to the size of the stator punching sheet. The positioning component 2 allows the stator punching sheet to be positioned when a plurality of stator punching sheets are abutted, so that the slots between the plurality of stator punching sheets can be aligned after being stacked, thereby avoiding affecting the stacking quality of the stator punching sheets, and stator punching sheets of different sizes can be positioned, thereby improving the scope of application and practicality.

[0055] The fixing components 3 are symmetrically arranged on both sides of the fixing frame 102;

[0056] The fixing assembly 3 includes an electric cylinder 301 symmetrically installed above both sides of the fixing frame 102, and a rubber plate 302 is fixedly installed on the movable end of the electric cylinder 301, and a limit rod 303 is symmetrically installed on both sides of the rubber plate 302 located on the movable end of the electric cylinder 301, and the limit rod 303 is symmetrically connected to the fixing frame 102.

[0057] Embodiment 2: Figure 1 and Fig. 9As shown, after the stator punching sheets are stacked, the two electric cylinders 301 can be started to drive the rubber plate 302 to move. The rubber plate 302 can fit the outside of the stator core due to its own soft material, and the rubber plate 302 drives the limit rod 303 to slide on the fixed frame 102 for limiting during the movement, so that the stator core can be fixed. Then, the stator core is pressed down by the pressing component 4. After the stator core is stacked, the turntable 217 can be rotated in the opposite direction, so that the positioning punching sheets are no longer positioned, and the movable frame 105 is driven to move by the electric push rod 104. During the movement of the movable frame 105, the support rod 106 is driven to slide on the workbench 1 for limiting, so that the two groups of rubber plates 302 leave the stator core. Then, a support plate can be set under the stator core, and the fixed component 3 no longer fixes the stator core. The stator core can be taken out by moving the support plate, so that the positioning component 2 can leave the stator core, which is convenient for removing the stator core and improves practicality.

[0058] The pressing assembly 4 is arranged above the interior of the fixing frame 102;

[0062] Embodiment 3: Figure 1 and Figure 9-11As shown, when the stator core is fixed, the movement of the rubber plate 302 contacts the ball 404 on the moving rod 403, the rubber plate 302 continues to move, and the ball 404 rotates on the rubber plate 302, so that the moving rod 403 slides inside the rectangular groove 402, so that the L-shaped rod 405 slides on the fixing block 406 and stretches the telescopic spring 407, so that when the stator cores of different sizes are fixed, the moving rod 403 can move with the movement of the rubber plate 302, and the overall size of the two groups of moving rods 403 can be adjusted, and then when the stator core is stacked, the hydraulic push rod 103 drives the X-shaped plate 401 to move downward, and the ball 404 rotates on the rubber plate 302, and the stator core can be stacked through the X-shaped plate 401 and the two groups of moving rods 403, and then when the stator cores of different sizes are stacked, there is no need to replace the pressing plate, thereby improving practicality.

[0063] Working principle: When using the stator core lamination equipment for motor production, first, according to Figure 1-Figure 11 As shown, before laminating the stator cores, multiple stator cores need to be stacked. First, a small number of stator cores can be stacked on the top of the placement plate 107 so that the two groups of rubber sleeves 204 are located in the slots of the positioning punches. When in use, lubricating products can be applied to the outside of the two groups of rubber sleeves 204. After stacking a small number of stator punches, the slots of a small number of stator punches cannot be aligned. At this time, the reduction motor 216 is started to drive the turntable 217 to rotate. After the turntable 217 rotates, the two groups of poles 202 can be pushed away from each other through the sliding connection between the through slot 218 and the pole 202. After the pole 202 moves, it drives the rubber sleeve 204 to move, so that the rubber sleeve 204 moves to the inside of the slot of the stator punch and fits the slot. During the movement, the pole 202 drives the positioning rod 208 to slide on the positioning block 209 for limiting. After the positioning rod 208 moves, the cylinder 213 can be moved by abutting against the cylinder 213. The cylinder 213 slides on the outside of the piston 212, so that the air inside the cylinder 213 can be compressed, and the air inside the cylinder 213 can be pushed into the connecting pipe 215. Then the air enters the rubber sleeve 204 through the connecting pipe 215, so that the rubber sleeve 204 can expand. During the expansion of the rubber sleeve 204, the support bar 207 is driven to move, so that the movable rod 206 slides inside the movable groove 205, thereby avoiding the support bar 207 from bending significantly, and avoiding the stator punching from being difficult to be sleeved on the outside of the rubber sleeve 204 during the subsequent stator punching stacking process, thereby making the rubber sleeve 204 fully fit with the slot on the stator punching, so that the stator punching can be positioned, and the inflation amount of the rubber sleeve 204 is proportional to the size of the stator punching.

[0064] After the stator punching sheets are stacked, the two electric cylinders 301 can be started to drive the rubber plate 302 to move. The rubber plate 302 can fit the outside of the stator core due to its own soft material, and the rubber plate 302 drives the limit rod 303 to slide on the fixed frame 102 for limiting during the movement, so that the stator core can be fixed. Then, the stator core is pressed down by the pressing component 4. After the stator core is stacked, the turntable 217 can be rotated in the opposite direction, so that the positioning punching sheets are no longer positioned, and the movable frame 105 is driven to move by the electric push rod 104. During the movement of the movable frame 105, the support rod 106 is driven to slide on the workbench 1 for limiting, so that the two groups of rubber plates 302 leave the stator core. Then, a support plate can be set under the stator core, and the fixed component 3 no longer fixes the stator core. The stator core can be taken out by moving the support plate, thereby The positioning assembly 2 can leave the stator core, which is convenient for removing the stator core. The movement of the rubber plate 302 contacts the ball 404 on the moving rod 403. The rubber plate 302 continues to move, and the ball 404 rotates on the rubber plate 302, so that the moving rod 403 slides inside the rectangular groove 402, so that the L-shaped rod 405 slides on the fixing block 406 and stretches the telescopic spring 407, so that when fixing stator cores of different sizes, the moving rod 403 can move with the movement of the rubber plate 302, and the overall size of the two groups of moving rods 403 can be adjusted. Then, when the stator core is stacked, the hydraulic push rod 103 drives the X-shaped plate 401 to move downward, and the ball 404 rotates on the rubber plate 302. The stator core can be stacked through the X-shaped plate 401 and the two groups of moving rods 403, and then when the stator cores of different sizes are stacked, there is no need to replace the pressing plate.
