Description

Technical Field

[0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a stator punching sheet overlapping alignment device. Background Art

[0002] The stator is the stationary part of the motor. Its main function is to generate a rotating magnetic field. The stator is made of several stator punchings that are stacked and limited. The stator core is an important part of the motor magnetic circuit. It is made of silicon steel sheets (also called electrical steel) punched into fan-shaped sheets or individual steel laminations stacked. These individual steel laminations or fan-shaped sheets are stacked together to form the overall structure of the stator core.

[0003] The existing stator punching overlap alignment device has the following problems:

[0004] The existing stator punching overlapping alignment device does not have the ability to clean the stator core before stacking, resulting in gaps in the stator core after stacking, affecting the welding quality of the stator laminations, thereby reducing the use efficiency of the stator lamination welding tooling, and the traditional stator punching overlapping alignment device does not have the ability to detect the gaps between the stator cores, therefore, it cannot meet the existing use requirements for the stator punching overlapping alignment device. Summary of the invention

[0006] The technical scheme adopted in this scheme is as follows: A stator punching overlapping alignment device proposed in this scheme includes a base, a slide, a driving frame, a fixed frame, a pressing type positioning mechanism and a magnetic pull type gap elimination mechanism.

[0008] When in use, rotate the compression bolt, the compression bolt is screwed out from the compression threaded hole, and the compression plate is taken down from the upper wall of the fixing frame, and then the stator core is sleeved on the outer side of the slide cylinder through the core slider, and the stator core slides down along the core slider to the upper wall of the rotating plate. Multiple groups of stator cores are stacked to form stator laminations and placed on the upper wall of the rotating plate. When the stator core is completely installed on the outer side of the slide cylinder, the compression plate is placed on the upper wall of the fixing frame, and the compression bolt is rotated. The compression bolt is screwed into the compression threaded hole, and the compression plate is fixed to the upper wall of the fixing frame. The compression plate drives the top plate column to squeeze the stacked stator cores through the compression seat, and the stator core is fixed between the rotating plate and the top plate column under the elastic action of the extension of the supporting spring, so as to facilitate the welding operation of the stacked stator cores.

[0009] Preferably, the magnetic push mechanism includes a magnetic push cavity, a push-down electromagnet, an push-up electromagnet, a magnetic push frame, a soft iron ring plate and a magnetic conductive port, the magnetic push cavity is arranged inside the slide, the push-down electromagnet is arranged on the bottom wall of the fixed frame, the push-up electromagnet is arranged on the upper wall of the driving frame, the push-down electromagnet and the push-up electromagnet are arranged opposite to each other, the magnetic push frame is arranged on the inner wall of the magnetic push cavity, the soft iron ring plate is arranged between the magnetic push frames, and multiple groups of the magnetic conductive ports are arranged on the side wall of the slide; the centrifugal mechanism includes a driving motor and a driving shaft, the driving motor is arranged on the bottom wall of the base, the driving shaft passes through the base and is arranged between the power end of the driving motor and the driving frame; the seam inspection mechanism includes a lighting seat and a lighting lamp, multiple groups of the lighting seats are arranged on the side wall of the soft iron ring plate, and the lighting lamp is arranged on the side of the lighting seat away from the soft iron ring plate.

[0010] During use, iron filings and impurities will be absorbed on the surface of the stator core, resulting in gaps between the stacked stator cores, affecting the welding effect of the stator cores. The push-down electromagnet is energized to generate magnetism, and the push-down electromagnet magnetizes the soft iron ring plate through magnetic force. The soft iron ring plate magnetizes the stator core sleeved on the outside of the slide cylinder through the magnetic guide port. The magnetic poles between the stator cores are the same. As the input current inside the push-down electromagnet increases, the magnetization force of the soft iron ring plate on the stator core is enhanced. Since the magnetic poles between the stator cores are the same, the stator cores repel each other through repulsion, and the elastic deformation of the supporting spring causes the stator cores to repel each other. Under the action, the distance between the stator cores increases. In the electromagnetic field of the soft iron ring plate, the magnetic field strength of the soft iron ring plate gradually weakens with the increase of distance. The magnetic field strength of the soft iron ring plate close to the push-down electromagnet is larger, and the magnetic field strength of the soft iron ring plate away from the push-down electromagnet is the smallest, so that the magnetization force of the stator core from top to bottom gradually decreases, and the magnetic field strength of the upper stator core is greater than that of the lower stator core. The upper stator core absorbs the metal impurities on the upper wall of the lower stator core through magnetic force, and the contact area between the metal impurities on the upper wall of the lower stator core and the metal impurities is reduced, and the metal impurities When the adsorption force on the upper wall of the lower stator core is reduced, the driving motor drives the driving frame to rotate through the driving shaft, and the driving frame drives the core slider to rotate through the slide cylinder, and the core slider drives the stator core sleeved on the outer side of the slide cylinder to rotate. The metal impurities on the upper wall of the lower stator core are weakened due to the adsorption force. Under the action of the centrifugal motion of the stator core, the metal impurities adsorbed on its upper wall are thrown off. Subsequently, the downward electromagnet is powered off to demagnetize, and the upward electromagnet is powered on to generate magnetism. At this time, the magnetic field strength at both ends of the soft iron ring plate is reversed, and the magnetic field strength of the lower stator core is greater than that of the upper stator core, which makes the lower stator core The stator core absorbs the metal impurities on the bottom wall of the upper stator core, weakening the force of the metal impurities adsorbed on the bottom wall of the upper stator core, making it easier to remove the metal impurities adsorbed on the upper and bottom walls of the stator core during centrifugal motion. The upward electromagnet is powered off and demagnetized, and the stator cores are stacked together under the elastic rebound of the supporting spring. The lighting lamp illuminates the inside of the magnetic push cavity, and the magnetic push cavity guides the light out through the magnetic guide port. When the light is not emitted from between the stator cores, it indicates that there are no impurities between the stator cores to prevent them from fitting together, so that the stator cores without gaps after fitting together can be welded.

[0011] Specifically, a controller is provided on the bottom wall of the base.

[0012] Wherein, the controller is electrically connected to the push-down electromagnet, the push-up electromagnet, the drive motor and the lighting lamp respectively.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the prior art, this solution adopts the method of magnetic conduction and centrifugal impurity removal. Through the set pressing type positioning mechanism and magnetic pull type gap elimination mechanism, under the coordinated use of the supporting mechanism, the top plate mechanism, the magnetic push mechanism, the centrifugal mechanism and the seam detection mechanism, the stator core is sleeved on the outer side of the slide cylinder through the core slider, and the stator core slides along the core slider and falls to the upper wall of the rotating plate, which can prevent the stator core from being dislocated and deflected. The magnetic field strength of the end of the soft iron ring plate close to the push-down electromagnet is larger, and the magnetic field strength of the end of the soft iron ring plate away from the push-down electromagnet is smaller. The magnetization force of the stator core is minimized, so that the magnetization force of the stator core gradually decreases from top to bottom. The magnetic field strength of the upper stator core is greater than that of the lower stator core. The upper stator core absorbs the metal impurities on the upper wall of the lower stator core through magnetic force. The contact area between the metal impurities on the upper wall of the lower stator core and the metal impurities is reduced. The adsorption force of the metal impurities on the upper wall of the lower stator core is reduced. Under the rotational force of the drive motor driving the slide, the metal impurities adsorbed on the surface of the stator core can be separated, thereby ensuring the processing efficiency of the stator core during welding operations to a certain extent.

[0031] The magnetic push mechanism 19 includes a magnetic push cavity 20, a push-down electromagnet 21, an push-up electromagnet 22, a magnetic push frame 23, a soft iron ring plate 24 and a magnetic guide port 25. The magnetic push cavity 20 is arranged inside the slide 2, the push-down electromagnet 21 is arranged on the bottom wall of the fixed frame 4, the push-up electromagnet 22 is arranged on the upper wall of the driving frame 3, the push-down electromagnet 21 and the push-up electromagnet 22 are arranged opposite to each other, the magnetic push frame 23 is arranged on the inner wall of the magnetic push cavity 20, and the soft iron ring plate 24 is arranged on the magnetic push frame 23.

[0032] A controller 32 is disposed on the bottom wall of the base 1 .

[0033] The controller 32 is electrically connected to the push-down electromagnet 21 , the push-up electromagnet 22 , the drive motor 27 and the lighting lamp 31 , respectively.

[0034] When in use, the compression bolt 15 is manually rotated, and the compression bolt 15 is unscrewed from the compression threaded hole 14, and the compression plate 13 is removed from the upper wall of the fixing frame 4. Then, the stator core is sleeved on the outer side of the slide cylinder 2 through the core slider 11. The stator core slides along the core slider 11 and falls to the upper wall of the rotating plate 10. Multiple groups of stator cores are stacked to form stator laminations and placed on the upper wall of the rotating plate 10. When all the stator cores are installed on the outer side of the slide cylinder 2, The pressing plate 13 is put into the upper wall of the fixing frame 4, and the pressing bolt 15 is rotated. The pressing bolt 15 is screwed into the inside of the pressing threaded hole 14, and the pressing plate 13 is fixed to the upper wall of the fixing frame 4. The pressing plate 13 drives the top plate column 17 to squeeze the stacked stator cores through the pressing seat 16. Under the elastic effect of the extension of the supporting spring 8, the stator core is fixed between the rotating plate 10 and the top plate column 17, which is convenient for welding the stacked stator cores.

[0035] During the production process of the stator core, iron filings and impurities will be adsorbed on the surface of the stator core, resulting in gaps between the stacked stator cores, which will affect the welding effect of the stator core. The controller 32 controls the push-down electromagnet 21 to start, and the push-down electromagnet 21 is energized to generate magnetism. The push-down electromagnet 21 magnetizes the soft iron ring plate 24 through magnetic force, and the soft iron ring plate 24 magnetizes the stator core sleeved on the outside of the slide cylinder 2 through the magnetic guide port 25. The magnetic poles between the stator cores are the same. As the input current inside the push-down electromagnet 21 increases, the magnetization force of the soft iron ring plate 24 on the stator core is enhanced. Since the magnetic poles between the stator cores are the same, the stator cores repel each other through repulsion, and the support spring 8 Under the action of elastic deformation, the spacing between the stator cores increases. In the electromagnetic field of the soft iron ring plate 24, the magnetic field strength of the soft iron ring plate 24 gradually weakens as the distance increases. The magnetic field strength of the end of the soft iron ring plate 24 close to the push-down electromagnet 21 is relatively large, and the magnetic field strength of the end of the soft iron ring plate 24 far from the push-down electromagnet 21 is the smallest, so that the strength of the magnetization of the stator core from top to bottom gradually decreases, and the magnetic field strength of the upper stator core is greater than that of the lower stator core. The upper stator core absorbs the metal impurities on the upper wall of the lower stator core through magnetic force, and the contact area between the metal impurities on the upper wall of the lower stator core and the metal impurities is reduced, and the adsorption strength of the metal impurities on the upper wall of the lower stator core is reduced;

[0036] The controller 32 controls the drive motor 27 to start, and the drive motor 27 drives the drive frame 3 to rotate through the drive shaft 28. The drive frame 3 drives the core slider 11 to rotate through the slide cylinder 2, and the core slider 11 drives the stator core sleeved on the outer side of the slide cylinder 2 to rotate. The metal impurities on the upper wall of the lower stator core are weakened due to the adsorption force. Under the action of the centrifugal motion of the stator core, the metal impurities adsorbed on the upper wall are thrown off. Subsequently, the controller 32 controls the push-down electromagnet 21 to power off and demagnetize. The controller 32 controls the push-up electromagnet 22 to start, and the push-up electromagnet 22 is energized to generate magnetism. At this time, the magnetic field strength at both ends of the soft iron ring plate 24 is reversed, and the magnetic field strength of the lower stator core is greater than that of the upper stator core, so that the lower stator core adsorbs the metal impurities on the bottom wall of the upper stator core, and the strength of the metal impurities adsorbed on the bottom wall of the upper stator core is weakened, so that the metal impurities adsorbed on the upper wall and bottom wall of the stator core are removed during the centrifugal motion.

[0037] The controller 32 controls the upward electromagnet 22 to cut off the power and demagnetize, and the stator cores are stacked together under the elastic rebound of the supporting spring 8. The controller 32 controls the lighting lamp 31 to start, and the lighting lamp 31 illuminates the inside of the magnetic push cavity 20. The magnetic push cavity 20 guides the light out through the magnetic guide port 25. When the light is not emitted from between the stator cores, it means that there are no impurities between the stator cores to prevent them from fitting together, so that the stator cores with no gaps after fitting together can be welded; the above operation can be repeated when used next time.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
