A stator core lamination device for motor production

Abstract

The present invention discloses a stator core lamination device for motor production, and the present invention relates to the field of core lamination technology. Since the core plates are stacked and then positioned, the edge of the bottom plate is close to the support table, resulting in the bottom plate being stuck in the gap position during positioning and clamping, and being unable to be adjusted, causing the bottom plate of the pressed core to be in the wrong pressed position and offset. The stator core lamination device for motor production, through the cooperation of the inner pad and the bottom pad, utilizes the rubber deformation characteristics to lift the tray when stacking the core plates, so that when the annular plates are stacked, there is a gap between the edge positions of the inner and outer sides of the plates and the support table. During positioning and clamping, the bottom plate is driven to avoid the edge of the bottom plate being close to the support table, resulting in the bottom plate being stuck in the gap position during positioning and clamping, and being unable to be adjusted, causing the bottom plate of the pressed core to be in the wrong pressed position and offset.

Description

Technical Field

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

[0002] The stator core is usually composed of hot-rolled or cold-rolled silicon steel sheets or iron-nickel soft magnetic alloy sheets, which are punched and stacked. It is made of materials with high magnetic permeability, which can provide a good magnetic path for the motor's magnetic field, guide the magnetic lines of force to concentrate on a specific path to form an effective magnetic field, enhance the magnetic field strength, and realize the conversion of electrical energy into mechanical energy. The slot structure of the stator core provides a precise installation position for the stator winding. The winding is embedded in the core slot and isolated by insulating material to ensure that the winding remains stable during motor operation. It also protects the winding from damage due to external mechanical and thermal stress. Stator core lamination refers to the process of stacking the punched silicon steel sheets according to design requirements and forming an integral core through processes such as applying pressure and tightening.

[0003] In existing lamination equipment, since the core plates are stacked and then positioned, the edge of the bottom plate is close to the support table, resulting in the bottom plate being stuck in the gap during positioning and clamping and unable to be adjusted, causing the bottom plate of the pressed core to be in the wrong pressing position and offset. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A pressing mechanism, the top of which is fixedly connected to the output end of the first cylinder, and the pressing mechanism is located inside the frame and directly above the support platform;

[0009] The top of the support table is provided with a groove, and a tray is slidably installed in the groove of the support table, the top of the pallet is evenly provided with grooves, and the grooves of the pallet are all clamped with rubber strips, and the bottom of the pallet is fixedly installed with a bottom pad, and the center position of the top of the support table is provided with a circular groove, and the circular groove of the support table is fixedly installed with an inner pad. The inner pad cooperates with the bottom pad and utilizes the rubber deformation characteristics. When stacking the core plates, the pallet is lifted up so that when the annular plates are stacked, there is a gap between the edge positions of the inner and outer sides of the plates and the support table, which is convenient for stacking. The worker adjusts the position of the bottom plate, and at the same time, the clamping adjustment of the auxiliary positioning mechanism and the restriction of the plate by the slot rod drive the bottom plate during positioning and clamping to avoid the bottom plate from being The top of the rotating slot disk is fixedly mounted with an inner top plate, and the bottom pad and the inner pad are both made of rubber.

[0011] The top roller is located between the side pressure rollers and the top of the support platform, and the distance between the inner top roller and the support platform is greater than the distance between the side pressure rollers and the support platform.

[0012] Preferably, the pressing mechanism includes a pressure plate, the center position of the top of the pressure plate is fixedly connected to the output end of the first cylinder, the bottom of the pressure plate is provided with a bottom ring groove, and the bottom ring groove of the pressure plate is slidably installed with an inner pressure ring, and the inner pressure ring cooperates with the pressure plate. During the pressing process, the inner pressure ring first contacts the top plate to pre-press the plate, and then in the process of continuous downward pressure, the pressure plate begins to contact the plate to avoid the plate from warping during pressing.

[0013] The present invention provides a stator core lamination device for motor production. It has the following beneficial effects:

[0014] 1. The stator core lamination equipment for motor production cooperates with the inner pad and the bottom pad, and utilizes its rubber deformation characteristics. When stacking the core plates, the tray is lifted up so that when the annular plates are stacked, there is a gap between the edges of the plates on both sides and the support platform, which is convenient for stacking. The worker adjusts the position of the bottom plate. At the same time, the clamping adjustment of the auxiliary positioning mechanism and the restriction of the plate by the slot rod drive the bottom plate during positioning and clamping to prevent the edge of the bottom plate from being close to the support platform. As a result, the bottom plate is stuck in the gap position during positioning and clamping, and cannot be adjusted. As a result, the pressing position of the bottom plate of the pressed core is incorrect and offset.

[0015] 2. The stator core stacking equipment used in motor production cooperates with the inner top plate through the slot rod. During the positioning, clamping and pressing process, the slot rod is supported by the inner top plate so that the slot rod and the groove position of the stacked core are clamped and corresponded, avoiding the slot rod tilting under pressure during the clamping, positioning and pressing process, making it impossible to position the stacked core, resulting in an offset in the stacking position.

[0016] 3. The stator core stacking equipment used in the production of the motor first contacts the side of the stacked core through the inner top roller to clamp the stacked core, and cooperates with the subsequent side pressure roller to clamp the core plate so that the center position of the stacked core corresponds to the center position of the support platform. At the same time, the arc surface of the inner top roller and the side pressure roller is used to contact the core to reduce the contact area with the core, avoiding damage to the side of the core due to the large contact area during the positioning and clamping process.

[0017] 4. The stator core lamination equipment used in the production of this motor cooperates with the inner pressure ring and the pressure plate. During the pressing process, the inner pressure ring first contacts the top plate to pre-press the plate. Then, during the continuous downward pressure, the pressure plate begins to contact the plate to avoid the plate from warping during pressing. Direct pressing in the warped state will cause misalignment between the plates after the core is pressed.

[0018] 5. The stator core lamination equipment used in the production of this motor first contacts the plate at the top of the stacking position during the pressing process through the side arc plate, adjusts the position of the plate, and cooperates with the clamping of the positioning mechanism to avoid the top plate from shifting.

[0030] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution:

By adjusting the position of the slot rod 7 according to the groove on the inner side of the core plate, the slot rod 7 slides in the annular groove of the rotating groove disk 10, so that the slot rod 7 corresponds to the groove of the core, and at the same time, the slot rod 7 is evenly distributed inside the stacked core to position the stacked core. At the same time, after the stacking is completed, the stacked core is squeezed together with the positioning mechanisms 2 on both sides to adjust the position between the stacked core plates so that the pressing position between the core plates is aligned. A circular groove is provided at the center position of the top of the support platform 5, and an inner pad 11 is fixedly installed at the circular groove of the support platform 5, and a rotating slot disk 10 is fixedly installed on the top of the inner pad 11. An annular groove is provided on the outer side of the rotating slot disk 10, and a slot rod 7 is rotatably installed at the annular groove of the rotating slot disk 10. During the pressing process, the deformation characteristics of the rubber material of the bottom pad 12 and the inner pad 11 are coordinated so that the stacked iron cores can move down a certain distance through deformation during pressing, providing a buffer for the pressing contact. At the same time, during the pressing process, the slot rod 7 is supported by the inner top plate 9, and the inner top plate 9 is fixedly installed on the top of the rotating slot disk 10. The bottom pad 12 and the inner pad 11 are both made of rubber material.

[0036] The second embodiment, based on the first embodiment, see Figures 5 to 7As shown, the positioning mechanism 2 includes a fixed plate 201, a side plate 202 is fixedly installed on the top of the fixed plate 201, the side plate 202 is symmetrically installed along the center position of the axis of the fixed plate 201, and a sliding groove is symmetrically opened on the outer side of the side plate 202, a second cylinder 203 is fixedly installed on the outer side of the side plate 202, the second cylinder 203 corresponds to the sliding groove of the side plate 202 one by one, and a connecting block 204 is fixedly installed on the output end of the second cylinder 203, and the connecting block 204 is slidably adapted to the sliding groove of the side plate 202. When the core plates are stacked, the fixed plates on both sides are The second cylinder 203 in the positioning mechanism 2 drives the connecting plate 207 to approach the stacked iron cores through the connecting block 204. During the approaching process, the supporting plate 208 and the orifice plate 211 are driven by the connecting plate 207, and the stacked iron cores are first contacted through the inner top roller 206. The connecting plate 207 is fixedly installed on the end of the connecting block 204 away from the second cylinder 203, and the support plate 208 is fixedly installed at the center position of the opposite surface of the connecting plate 207. The orifice plate 211 is fixedly installed between the support plates 208, and the outer side of the orifice plate 211 is symmetrically provided with sliding holes.

[0037] The side of the support plate 208 close to the support platform 5 is fixedly installed with a side pressure roller 205, and the sliding hole of the orifice plate 211 is slidably installed with a connecting rod 209. The end of the connecting rod 209 close to the support platform 5 is fixedly installed with an inner top roller 206. The bottom of the inner top roller 206 and the side pressure roller 205 are flush with the top of the support platform 5. The end of the connecting rod 209 away from the inner top roller 206 is fixedly installed with a limiting disk 210. After contacting the stacked iron core, the contact pressure between the inner top roller 206 and the iron core is transmitted to the connecting rod 209, so that the connecting rod 209 is in the orifice plate. The spring 212 is driven to stretch and deform through the limit plate 210 while sliding, so that the spring 212 generates elastic force, and then the side pressure roller 205 contacts the two sides of the iron core, so that the side pressure rollers 205 on both sides cooperate with each other to adjust the pressing position between the stacked iron core plates under the clamping pressure. The spring 212 is fixedly installed between the limit plate 210 and the hole plate 211, and the inner top roller 206 is located between the side pressure rollers 205, and the distance between the inner top roller 206 and the support platform 5 is greater than the distance between the side pressure roller 205 and the support platform 5.

[0038] The third embodiment, based on the first and second embodiments, see Figures 8 and 9As shown, the pressing mechanism 3 includes a pressure plate 31, the center position of the top of the pressure plate 31 is fixedly connected to the output end of the first cylinder 4, the bottom of the pressure plate 31 is provided with a bottom ring groove, and an inner pressure ring 36 is slidably installed at the bottom ring groove of the pressure plate 31, and the outer side of the inner pressure ring 36 is evenly provided with notches, and the pressure plate 31 is driven downward by the first cylinder 4. During the downward movement, the side arc plates 37 on both sides of the bottom of the outer sliding cover 32 first contact the top plate of the stacked iron core, and cooperate with the positioning mechanism 2 to position the position of the iron core plate. At the same time, during the pressing process, the contact pressure is transmitted to the inner gasket 34 through the outer sliding cover 32, causing the inner gasket 34 to deform, and the outer sliding cover 32 moves up, causing the inner pressure ring 36 to start contacting the top plate to pre-press the plate. An annular convex The top of the inner pressure ring 36 is fixedly installed with a fixed shaft 35, and the top of the fixed shaft 35 passes through the pressure plate 31 and extends to its top, and the top of the fixed shaft 35 is fixedly installed with a limit block 33.

[0039] During use, workers stack the required stacked stator cores on top of the support platform 5 and support the cores through the support platform 5. Then the workers start the positioning mechanisms 2 on both sides, and squeeze and adjust the stacked cores through the positioning mechanisms 2 so that the pressing positions between the core plates correspond. Finally, the workers start the first cylinder 4, so that the first cylinder 4 drives the pressing mechanism 3 to move downward, contact the top of the stacked cores, and press the cores.

[0040] When workers stack the iron cores, they adjust the position of the slot rod 7 according to the groove on the inner side of the iron core plate, so that the slot rod 7 slides in the annular groove of the rotating slot plate 10, so that the slot rod 7 corresponds to the groove of the iron core, and at the same time, the slot rod 7 is evenly distributed inside the stacked iron core to position the stacked iron core. At the same time, after the stacking is completed, the stacked iron core is squeezed together with the positioning mechanisms 2 on both sides to adjust and position the positions between the stacked iron core plates so that the pressing positions between the iron core plates correspond. During the pressing process, the deformation characteristics of the rubber materials of the bottom pad 12 and the inner pad 11 are cooperated so that during pressing, the stacked iron cores can be moved down a certain distance through deformation, providing a buffer for the pressing contact. At the same time, during the pressing process, the slot rod 7 is supported by the inner top plate 9.

[0041] In the positioning mechanism 2, when the iron core plates are stacked, the second cylinder 203 in the positioning mechanisms 2 on both sides drives the connecting plate 207 to approach the stacked iron cores through the connecting block 204. In the process of approaching, the support plate 208 and the orifice plate 211 are driven by the connecting plate 207, and the stacked iron cores are first contacted by the inner top roller 206. After contacting the stacked iron cores, the contact pressure between the inner top roller 206 and the iron cores is transmitted to the connecting rod 209, causing the connecting rod 209 to slide in the sliding hole of the orifice plate 211. While sliding, the spring 212 is driven to stretch and deform through the limit plate 210, causing the spring 212 to generate elastic force, and then the side pressure roller 205 contacts both sides of the iron core, so that the side pressure rollers 205 on both sides cooperate with each other to adjust the pressing position between the stacked iron core plates under clamping pressure.

[0042] In the pressing mechanism 3, the pressure plate 31 is driven downward by the first cylinder 4. During the downward movement, the side arc plates 37 on both sides of the bottom of the outer sliding cover 32 first contact the top plate of the stacked iron core, and cooperate with the positioning mechanism 2 to position the position of the iron core plate. At the same time, during the pressing process, the contact pressure is transmitted to the inner gasket 34 through the outer sliding cover 32, causing the inner gasket 34 to deform, and the outer sliding cover 32 moves upward, so that the inner pressure ring 36 begins to contact the top plate to pre-press the plate. In the process of continuous downward movement and pressure application, the inner pressure ring 36 slides upward in the annular groove of the pressure plate 31, so that the pressure plate 31 gradually contacts the plate, and under the drive of the first cylinder 4, the stacked iron core plates are pressed together to form the iron core as a whole.
