Description

Technical Field

[0001] The utility model relates to the technical field of motor stator core installation, in particular to a detachable slot-like shaping device. Background Art

[0002] The slot-shaped shaping device for the conventional motor stator core stacking installation is a round or slot-shaped rod. The disadvantage of this type of slot-shaped shaping device is that when the core punching sheets are stacked, the punching sheet slot shape needs to be correspondingly inserted into several slot-shaped shaping devices, which will increase the axial friction damping caused by the stacking of the core punching sheets. The friction force can easily cause damage to the punching sheet slot flange.

[0003] After the stator core is stacked and installed, the slot shaping device needs to be removed from the stator core. Since this type of slot shaping device is in close contact with the stator core slot shape, the withdrawal movement when withdrawing the slot shaping device will wear the core slot shape and even cause the slot-shaped pieces in local positions of the core to be misaligned, bringing technical problems that seriously affect product quality. Utility Model Content

The specific implementation method of the utility model is given in detail by the following embodiments and their drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of the present application. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0022] See also Figures 1 to 3The utility model provides a detachable slot-shaped shaping device. The detachable slot-shaped shaping device can be applied to the stacking and installation of motor stator core punching sheets 500, and is used to shape and position the punching sheets 500 when the punching sheets 500 are stacked.

[0023] The detachable groove-like shaping device comprises a first module 1 and a fixing member 2. The first module 1 has a first fitting surface 11 and a first shaping surface 12. The fitting surface 11 is formed with a plurality of first grooves extending vertically. The plurality of first modules 1 are arranged in an interlaced manner and the fitting surfaces 11 are interlaced and fitted in an interlaced manner.

[0024] Those skilled in the art can easily understand that the first bonding surfaces 11 of the two first modules 1 are relatively staggered and bonded, that is, part of the first bonding surfaces 11 are bonded together, part of the first bonding surfaces 11 extend from both ends, and then the part of the first bonding surfaces 11 extending from both ends are used to bond with the first bonding surfaces 11 of other first modules 1. The first modules 1 are continuously combined together according to this method until the required length is reached.

[0025] The shape of the first shaping surface 12 is the same as the shape of the groove of the punching sheet 500. The first module 1 is spliced ​​and connected with the grooves of each punching sheet 500 to shape and position each punching sheet 500. And each first groove is connected in sequence and enclosed together to form a plurality of positioning holes. The fixing parts 2 are inserted into the positioning holes one by one to fix the first module 1.

[0026] In actual use, first, the first modules 1 are assembled together in the above-mentioned manner, the punching sheets 500 are stacked and sequentially sleeved on the modules 1, and then the fixing member 2 is inserted into the positioning hole for positioning to form a shaping device, and the punching sheets 500 are shaped and positioned by cooperating with the groove of the punching sheets 500. When dismantling the shaping device, the fixing member 2 is first pulled out, and the punching sheets 500 are separated from the first module 1 before the first module 1 is taken out. Obviously, in the entire disassembly and assembly process, the sliding friction mainly occurs between the fixing member 2 and the first module 1, and the first module 1 is separated from the punching sheets 500, and no friction is generated. The friction between the traditional shaping device and the punching sheets 500 is converted into the friction between the fixing member 2 and the first module 1, protecting the punching sheets 500 from damage and deformation.

[0027] The use of the first module 1 for assembly may lead to unevenness at both ends of the shaping device. Therefore, in some embodiments, a second module 3 is also included. The second module 3 has a second fitting surface and a second shaping surface. The second fitting surfaces of the two second modules 3 are respectively arranged to fit with the first fitting surfaces of the two first modules 1 located at both ends, and the first shaping surface and the second shaping surface are flush.

[0028] Correspondingly, a plurality of second grooves penetrating vertically are formed on the second fitting surface. The second grooves can be connected to the first grooves correspondingly to form positioning holes together, so that the fixing member 2 can pass through.

[0029] In some embodiments, the area of ​​the first bonding surfaces 11 of two first modules 1 that are bonded is half of the total area of ​​the first bonding surfaces 11 .

[0030] Correspondingly, in the embodiment with the second module 3, the area of ​​the second bonding surface is half of the area of ​​the first bonding surface 11, so as to fill the redundant first bonding surface 11 at both ends.

[0031] In a preferred embodiment, the first module 1 and the second module 3 are both columnar structures and have the same cross-section, but the height of the second module 3 is only half of that of the first module 1, so that two second modules 3 can be spliced ​​into one first module 1. That is, when the first modules 1 are staggered and laminated, only half of the first laminating surface 11 is laminated, and the two ends are laminated with the second modules 3 to form a complete shaping device.

[0032] In some embodiments, the first shaping surface 12 is formed with a first positioning groove that passes through from top to bottom. The second shaping surface is formed with a second positioning groove that passes through from top to bottom, and the second positioning groove can be connected to the first positioning groove. Both the first positioning groove and the second positioning groove are adapted to the shape of the punching sheet 500.

[0033] In some embodiments, the first groove and the second groove are both semicircular grooves with the same inner diameter. The fixing member 2 is a cylindrical structure, and its outer diameter is larger than the inner diameter of the first groove. When the fixing member 2 is inserted into the positioning hole, the first module 1 and the second module 3 can be spread apart, so that the first module 1 and the second module 3 are pressed against the punching sheet 500 to achieve positioning shaping.

[0034] Compared with the prior art, the detachable groove-like shaping device provided by the utility model adopts a splicing structure, and uses fixing parts to fix each first module to form the entire shaping device. The fixing parts are used to realize the disassembly and assembly of the punching sheet, and the friction between the traditional shaping device and the punching sheet is converted into the friction between the fixing parts and the first module, thereby protecting the punching sheet from damage and deformation.

[0035] 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 changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
