In the field of industrial automation, motors are widely used. The existing motor basically needs to be laminated with silicon steel sheets in the production and assembly process, but a universal device which is convenient to laminate the silicon steel sheets is not provided at present, so that the silicon steel sheets are not conveniently laminated, the laminating process needs to be replaced by welding when necessary, and the motor is not easy to operate and has poor laminating precision.
In view of this, the present invention provides a silicon steel sheet laminating apparatus, and fig. 1 to 3 illustrate an embodiment of the silicon steel sheet laminating apparatus according to the present invention.
Referring to fig. 1 to 3, a silicon steel sheet laminating apparatus 100 according to the present invention includes a base plate 1 and a limiting structure 2, wherein the base plate 1 has a laminating area (not marked) for placing a plurality of silicon steel sheets 300; the limiting structure 2 is arranged on the bottom plate 1 and located on the periphery of the overlapping area, and is used for limiting the plurality of silicon steel sheets 300 in the circumferential direction of the plurality of silicon steel sheets 300.
In the technical scheme provided by the invention, the arrangement of the bottom plate 1 is that the silicon steel sheet 300 provides a stable bearing surface; the arrangement of the overlapping area indicates the accurate placement position of the silicon steel sheet 300; the arrangement of the limiting structure 2 can limit the circumferential directions of the silicon steel sheets 300, so that the overlapping operation of the silicon steel sheets 300 is facilitated, the position deviation of the silicon steel sheets 300 in the overlapping process can be avoided, and the overlapping precision is reduced.
It should be noted that the silicon steel sheet laminating device 100 of the present design can cooperate with other devices such as a manipulator and the like to form a laminating device together, and the laminating device is applied to the laminating process of the silicon steel sheets 300, and at this time, the process of installing the limiting structure 2 to the bottom plate 1 and the laminating processes of the plurality of silicon steel sheets 300 can be automatically completed by the manipulator, which is more beneficial to improving the laminating efficiency and the laminating precision; of course, the silicon steel sheet laminating device 100 of the present design can also be independently applied to the laminating process of the silicon steel sheet 300, and at this time, the process of installing the limiting structure 2 to the bottom plate 1 and the laminating process of the plurality of silicon steel sheets 300 can be manually completed by the operator, which is more beneficial to saving the economic cost.
In view of the above, the base plate 1 may be a plate-like structure formed on the main body of the laminating apparatus, or may be a separate plate member; the bottom plate 1 has a bearing surface forming a stacking area, and the bearing surface can be oriented at any direction, for example, can be optionally arranged upwards, which is more favorable for the stability of the silicon steel sheet 300 when being placed; the shape and size of the overlapping area are matched with the silicon steel sheet 300 to be overlapped, and the size of the overlapping area is selected to be slightly larger than the size of the silicon steel sheet 300, so that the alignment and the correction of the limiting structure 2 in the installation process are facilitated.
In addition, there are various technical solutions of the limiting structure 2 that can achieve the above functions, wherein, for example, the limiting structure 2 includes a frame-shaped enclosure member, and the shape of the frame inside the frame-shaped enclosure member is matched with the contour of the silicon steel sheet 300. In this embodiment, the limiting structure 2 includes a plurality of limiting blocks 21, and the plurality of limiting blocks 21 are arranged along the circumferential interval of the overlapping region. The arrangement of the plurality of limiting blocks 21 ensures that the installation and the disassembly of each limiting block 21 can be independent without influencing other limiting blocks 21; moreover, the installation positions of at least some of the limiting blocks 21 are changed, so that the silicon steel sheet laminating device 100 can be adapted to silicon steel sheets 300 with various shapes and sizes, and is more universal.
Further, in this embodiment, the plurality of limiting blocks 21 include first limiting blocks 211 disposed corresponding to the corners of the silicon steel sheets 300, and the first limiting blocks 211 define corner slots 212 for the corners of the silicon steel sheets 300 to be clamped. The in-groove shape of the corner groove 212 is adapted to the corner shape of the silicon steel sheet 300 at the position, for example, when the corner of the silicon steel sheet 300 is right-angled, the in-groove shape of the corner groove 212 is right-angled; when the corners of the silicon steel sheet 300 are rounded, the inner shape of the corner groove 212 is rounded. The setting of angle groove 212 for the butt face between first stopper 211 and the silicon steel sheet 300 presents for the form of bending, also can carry on spacingly to silicon steel sheet 300 in two directions at least, helps reducing the quantity that sets up of stopper 21, makes the structure simpler.
Furthermore, the number of the first limiting blocks 211 can be one, and the first limiting blocks 211 are used in cooperation with other limiting blocks 21 to limit the circumferential direction of the silicon steel sheet 300; of course, as in this embodiment, at least two first limit blocks 211 may be provided, and the two first limit blocks 211 are correspondingly disposed at diagonal positions of the overlapping region. Because the shape of the overlapped area is matched with the shape of the silicon steel sheet 300, the two first limiting blocks 211 are arranged at the diagonal positions of the overlapped area, namely, at the diagonal positions corresponding to the silicon steel sheet 300. For example, when the overall shape of the silicon steel sheet 300 is rectangular, the silicon steel sheet has four corners, and the four corners are distributed at two diagonal positions of the rectangle, the two first limiting blocks 211 are at least arranged at one diagonal position, and two acting forces facing each other along the diagonal are formed on the silicon steel sheet 300, which is helpful for the limiting structure 2 to limit the silicon steel sheet 300 more stably.
In addition, in this embodiment, if the overlapping region extends along the first dimension direction and the second dimension direction; the limiting block 21 is movably and adjustably mounted on the bottom plate 1 in the first dimension direction and/or the second dimension direction. With such an arrangement, the limiting block 21 is applicable to the silicon steel sheets 300 with various sizes, and can provide different abutting forces for the silicon steel sheets 300, so that the silicon steel sheet laminating device 100 has higher practicability. It should be noted that the stopper 21 includes the first stopper 211, and therefore, the first stopper 211 can also be movably installed on the bottom plate 1 along the first dimension direction and/or the second dimension direction.
Certainly, the technical scheme who realizes stopper 21 activity regulation in first dimension direction and/or second dimension direction has the multiple, for example, can set up one side that stopper 21 back to silicon steel sheet 300 and pass through an elastic component elastic mounting on bottom plate 1, and when the elastic component is in the state of relaxing, the region that a plurality of stoppers 21 enclosed and establish the constitution is less than silicon steel sheet 300's size, so, when silicon steel sheet 300 puts to stack and establishes the region in, promote stopper 21 and make elastic component compression deformation, form the reaction force of suppression in silicon steel sheet 300 corresponding position department, thereby realize the good spacing to silicon steel sheet 300.
However, considering that the elastic deformation capability of the elastic member is limited, and the plurality of position-limiting blocks 21 arranged in multiple directions are not convenient for simultaneous operation, in this embodiment, one of the position-limiting blocks 21 and the bottom plate 1 is provided with a long hole 31 extending along the movable adjusting direction of the position-limiting block 21, and the other corresponding long hole 31 is provided with a matching hole 32; the limiting structure 2 further comprises a fastening member (not shown in the figures), wherein the fastening member is provided with an extending section extending into the elongated hole 31 and a limiting section exposed out of the elongated hole 31, and the size of the limiting section is larger than the aperture of the elongated hole 31 at the position of the limiting section, so that the fastening member is prevented from completely immersing into the elongated hole 31; the protruding section passes through the elongated hole 31 and the fitting hole 32 to fixedly connect the stopper 21 and the base plate 1. Specifically, for example, the limiting block 21 is provided with an elongated hole 31, the bottom plate 1 is provided with a matching hole 32, an external thread may be provided at an end of the extending section of the fastening member, an internal thread may be provided in the hole of the matching hole 32, and when the limiting block 21 is adjusted to a proper position, the extending section of the fastening member is operated to pass through the elongated hole 31 and then be in threaded connection with the matching hole 32.
After the silicon steel sheets 300 are stacked, they need to be fixed, so as to prevent the silicon steel sheets 300 from loosening, for example, when each silicon steel sheet 300 has a plurality of connecting holes 301 at intervals, the silicon steel sheets 300 can be stably connected by the connection between the connecting member (not shown in the drawings) and the mating member (not shown in the drawings). Based on the above, in this embodiment, the silicon steel sheet laminating apparatus 100 further includes the positioning structure 4, and the positioning structure 4 is used for positioning and installing the connecting member, so as to fixedly connect the plurality of silicon steel sheets 300 to the connecting member.
The technical solution of the positioning structure 4 for realizing the above functions can be various, for example, the positioning structure 4 can be a mounting bracket for positioning and mounting the connecting piece. However, in the embodiment, when the connecting member is a nut and the mating member is a screw, the nut and the screw are screwed to fixedly connect the plurality of silicon steel sheets 300. In this regard, the positioning structure 4 comprises a counter bore 41 arranged in the overlap region, which counter bore 41 serves to capture the nut. The number of the counter bores 41 may be set to one or more to match the number of the coupling holes 301 of the silicon steel sheet 300. The counter bore 41 may be provided as a through hole through the base plate 1, and the diameter of at least a section of the counter bore 41 near the overlapping area is adapted to the size of the location of the nut. The shape of the counter bore 41 can be a waist-shaped hole, and the waist-shaped hole can limit the rotation of the nut, so that when the multiple silicon steel sheets 300 are completely stacked, the screw rod is operated to penetrate through the connecting holes 301 of the multiple silicon steel sheets 300 and extend into the threaded hole of the nut, and the screw rod can be directly rotated to realize the screw connection with the nut. It should be noted that the depth of the counter bore 41 is at least not less than the thickness of the connecting member, so as to avoid the connecting member protruding out of the plane of the stacking area when being clamped in the counter bore 41, which may cause unstable placement of the silicon steel sheet 300 in the stacking area.
