Description

Technical Field

[0001] The present disclosure relates to the technical field of electric motors, and in particular to a linear stator shaping device. Background Art

[0002] The motor comprises a fixed stator, which comprises a stator core, a stator winding and an insulating frame. The stator winding is wound on the stator core, and the insulating frame is wrapped around the outer periphery of the stator core.

[0003] The known stator cores include full-circle type and straight-chain type. The full-circle stator core is round during the manufacturing process; the straight-chain stator core is straight-chain during the manufacturing process, and after winding the stator winding, it is rolled into a round shape from the straight-chain type. Compared with the full-circle stator core, the straight-chain stator core can not only improve the winding efficiency by three-needle parallel winding during the winding process, but also improve the slot fill rate.

[0004] However, in the prior art, the linear stator core has a problem of large ovality after being rolled. Utility Model Content

[0005] The purpose of the present disclosure is to provide a straight-chain stator shaping device, so that the stator of a straight-chain motor has good roundness after being rolled.

[0006] To achieve the above objectives, the present disclosure provides a linear motor stator shaping device, comprising:

[0007] Internal rounded surface; and

[0008] A plurality of outer circle shaping components are arranged in a circumferential direction around the inner circle shaping surface, and the outer circle shaping components include:

[0009] Fixed seat;

[0010] an outer circle shaping block, the outer circle shaping block having an outer circle shaping surface, the outer circle shaping block being movably arranged between the fixing seat and the outer circle shaping surface; and

[0011] A driving member is connected between the fixing seat and the outer circle shaping block, and the driving member drives the outer circle shaping block to move between the fixing seat and the outer circle shaping surface.

[0012] According to the straight-chain motor stator shaping device disclosed in the present invention, when the straight-chain motor stator that has been roughly rolled in advance is installed on the straight-chain motor stator shaping device, the driving member can drive the outer circle shaping block to move toward the inner circle shaping surface, so that the outer circle shaping block abuts against the outer circle of the straight-chain motor stator, and the inner circle of the straight-chain motor stator abuts against the inner circle shaping surface, thereby ensuring that the inner circle and outer circle of the straight-chain motor stator are shaped at the same time, thereby ensuring the roundness of the straight-chain motor stator.

[0025] Figure 1 FIG. 1 shows a perspective view of a linear motor stator 1 after rolling. Figure 1 As shown, the linear chain motor stator 1 includes a plurality of chain links 11. Figure 1 The number of the middle chain links 11 is 6, however, in an embodiment not shown, the number of the chain links 11 may also be 12, 18, etc.

[0026] Before rolling, the plurality of chain links 11 are arranged along a straight line. Figure 1 As shown, a plurality of chain links 11 are arranged around the circumferential direction and connected end to end. The chain links 11 at both ends of the rolled chain can be welded and fixed by welding, so that the linear chain motor stator 1 is kept in a rolled state.

[0027] like Figure 1 As shown, the stator 1 of the linear motor after rolling is roughly in the shape of a ring, having an inner circle and an outer circle, and the inner circle and the outer circle are concentrically arranged.

[0028] Figure 2 Shown according to Figure 1 The perspective view of a chain link 11 of the linear chain motor stator 1 is shown in FIG. 1 , wherein the left side is an assembly view and the right side is an exploded view. Figure 2As shown, the chain link 11 includes a stator core 12, a stator winding (not shown) and an insulating frame. The stator core 12 includes a tooth portion 121 and a yoke portion 122. The tooth portion 121 is connected to the inner circumference of the yoke portion 122. The stator winding is wound on the tooth portion 121. The insulating frame includes an upper insulating frame 13 and an upper insulating frame 14. The upper insulating frame 13 is sleeved on the upper part of the stator core 12, and the lower insulating frame 14 is sleeved on the lower part of the stator core 12.

[0029] This embodiment provides a linear motor stator shaping device 2 for shaping a pre-rolled linear motor stator 1 into a circle, thereby ensuring the roundness of the pre-rolled linear motor stator 1.

[0030] Figure 3 FIG. 2 shows a perspective view of a linear motor stator shaping device 2. Figure 3 As shown, the linear chain motor stator shaping device 2 includes a base 21, on which an inner circle shaping column 22 and a plurality of outer circle shaping components 23 are arranged. The inner circle shaping column 22 is roughly cylindrical, and the side surface of the inner circle shaping column 22 is an inner circle shaping surface 221, which is adapted to the inner circle of the chain link 11. The plurality of outer circle shaping components 23 are arranged around the circumferential direction of the inner circle shaping surface 221, and can be evenly arranged in particular. The outer circle shaping assembly 23 includes a fixed seat 231, an outer circle shaping block 232 and a driving member 233. The fixed seat 231 is fixedly installed on the base 21. The outer circle shaping block 232 has an outer circle shaping surface 2321 adapted to the outer circle of the chain link 11. The outer circle shaping block 232 is movably arranged between the fixed seat 231 and the inner circle shaping surface 221. The driving member 233 is connected between the fixed seat 231 and the outer circle shaping block 232 so as to drive the outer circle shaping block 232 to move between the fixed seat 231 and the inner circle shaping surface 221.

[0031] When the straight-chain motor stator shaping device 2 is used, the straight-chain motor stator 1 is roughly rolled in advance, and then the inner circle of the chain link 11 is abutted against the inner circle shaping surface 221, and the outer circle of the chain link 11 is abutted against the outer circle shaping surface 2321, and then the outer circle shaping block 232 is driven toward the inner circle shaping column 22 by the driving member 233, so that the chain link 11 is positioned between the inner circle shaping surface 221 and the outer circle shaping surface 2321, ensuring that the straight-chain motor stator 1 is rolled, and then the chain links 11 at the head and tail ends can be welded and fixed to achieve the shaping of the straight-chain motor stator 1.

[0032] It can be seen that according to the straight-chain motor stator shaping device 2 disclosed in the present invention, when the straight-chain motor stator 1 that has been roughly rolled in advance is installed on the straight-chain motor stator shaping device 2, the driving member 233 can drive the outer circle shaping block 232 to move toward the inner circle shaping surface 221, so that the outer circle shaping block 232 abuts against the outer circle of the straight-chain motor stator 1, and the inner circle of the straight-chain motor stator 1 abuts against the inner circle shaping surface 221, thereby ensuring that the inner circle and outer circle of the straight-chain motor stator 1 are shaped at the same time, thereby ensuring the roundness of the straight-chain motor stator 1.

[0033] Figure 3 A schematic diagram of a linear motor stator shaping device 2 having six outer circle shaping components 23 is shown in the figure. However, in an embodiment not shown, the number of the outer circle shaping components 23 can be 12, 18, etc. Usually, the number of the outer circle shaping components 23 can be adapted to the number of the chain links 11 so as to shape each chain link 11.

[0034] In addition, if Figure 3 As shown, in this embodiment, there is a spacing area between two adjacent outer circle shaping components 23, through which the tools required for welding, such as a welding gun, can be inserted into the straight-chain motor stator shaping device 2, so as to perform welding operations on the straight-chain motor stator 1.

[0035] However, in an embodiment not shown, only one spacing region is required, that is, among the plurality of outer circle shaping components 23 , only two adjacent outer circle shaping components 23 need to have a spacing region between them.

[0036] Figure 4 Shown according to Figure 3 The schematic diagram of a part of the straight chain motor stator shaping device 2 is shown. Figure 4 As shown, the outer circle shaping block 232 has a threaded hole 2311, the axial direction of the threaded hole 2311 points to the inner circle shaping surface 221, and the driving member 233 has a threaded portion, which is threadedly connected in the threaded hole 2311, so that when the driving member 233 rotates, the driving member 233 can move axially in the threaded hole 2311, that is, the driving member 233 can move toward or away from the inner circle shaping surface 221. When the driving member 233 moves toward the inner circle shaping surface 221, the driving member 233 pushes the outer circle shaping block 232 to move toward the inner circle shaping surface 221, so that the stator 1 of the linear chain motor can be shaped.

[0037] In addition, since the driving member 233 is fixed to the fixing seat 231 by means of a threaded connection, when the driving member 233 is not rotating, the axial position of the driving member 233 in the threaded hole 2311 is fixed. Therefore, during the shaping process, the linear motor stator 1 can be kept at a desired position to facilitate the rolling process and welding.

[0038] like Figure 4 As shown, the outer circle shaping block 232 has a connecting hole 2324 facing the fixing seat 231, the connecting hole 2324 is a blind hole, and the diameter of the connecting hole 2324 is slightly larger than the diameter of the driving member 233, and the radial inner end of the driving member 233 abuts against the bottom of the connecting hole 2324, so that when the driving member 233 rotates and moves toward the inner circle shaping surface 221, the outer circle shaping block 232 can be pushed to move toward the inner circle shaping surface 221 without driving the outer circle shaping block 232 to rotate. When the driving member 233 rotates and moves away from the inner circle shaping surface 221, the driving member 233 separates from the outer circle shaping block 232, and also does not drive the outer circle shaping block 232 to rotate.

[0039] As an example of the driving member 233 , the driving member 233 is a screw fastener, such as a screw.

[0040] In addition, a plurality of driving members 233 may be installed on a fixing seat 231, and the plurality of driving members 233 are arranged along the axial direction of the outer circular shaping surface 2321. Thus, when the axial length of the linear motor stator 1 is large, a force may be applied to a plurality of positions of the linear motor stator 1 to ensure that the linear motor stator 1 is closely attached to the inner circular shaping surface 221 and the outer circular shaping surface 2321.

[0041] like Figure 4 As shown, the outer circle shaping assembly 23 also includes a guide member 234, which extends along a preset trajectory between the fixed seat 231 and the inner circle shaping surface 221, and the outer circle shaping block 232 is movably mounted on the guide member 234, whereby the moving trajectory of the outer circle shaping block 232 is limited by the guide member 234.

[0042] As an example, the guide member 234 may be a fixed rail fixedly mounted on the base 21 , or a guide rod passing through the fixed seat 231 .

[0043] As an example, the preset trajectory may be a trajectory extending radially along the inner circle shaping surface 221 .

[0044] like Figure 4 As shown, a support platform 2322 is provided on the outer circle shaping surface 2321 of the outer circle shaping block 232. The support platform 2322 is configured to support the linear motor stator 1 when the linear motor stator 1 is mounted on the outer circle shaping block 232 so that the lower insulating frame 14 is suspended, that is, there is no contact between the lower insulating frame 14 and the base 21, thereby avoiding friction between the lower insulating frame 14 and the base 21 during the movement of the outer circle shaping block 232.

[0045] like Figure 4As shown, the outer circle shaping surface 2321 of the outer circle shaping block 232 is also provided with a limit platform 2323, and the limit platform 2323 is located above the support platform 2322. The limit platform 2323 is configured to abut against the upper part of the straight-chain motor stator 1 when the straight-chain motor stator 1 is installed on the outer circle shaping block 232, so that the straight-chain motor stator 1 is limited between the support platform 2322 and the limit platform 2323.

[0046] Figure 5 Shown according to Figure 1 The linear motor stator 1 shown is installed according to Figure 3 The schematic diagram of the straight chain motor stator shaping device 2 is shown. Figure 5 As shown, when the straight-chain motor stator shaping device 2 is used, the straight-chain motor stator 1 is first roughly rolled in advance so that the straight-chain motor stator 1 can be placed in the straight-chain motor stator shaping device 2. During the placement process, the lower part of the straight-chain motor stator 1 is abutted against the support platform 2322 of the outer circle shaping block 232, and the upper part of the straight-chain motor stator 1 is abutted against the limit platform 2323 of the outer circle shaping block 232, and then the outer circle shaping components 23 are adjusted one by one. The driving member 233 drives the corresponding outer circle shaping block 232 to move toward the inner circle shaping surface 221, so that the outer circle shaping surface 2321 abuts against the outer circle of the linear chain motor stator 1 and the inner circle of the linear chain motor stator 1 abuts against the inner circle shaping surface 221, and finally the outer circles of all the chain links 11 abut against the outer circle shaping surface 2321, and the inner circles of all the chain links 11 abut against the inner circle shaping surface 221, and then the chain links 11 at both ends are welded and fixed.
