Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a linear integrated socket frame structure. Background Technology

[0002] To improve motor production efficiency and automation, existing motors often use a chain-like stator design. This means that a stator is divided into a number of equal parts equal to the number of slots, with each iron core continuously connected, unfolding like a chain. During production, the cores can be wound together and then assembled into a complete circle to form a stator.

[0003] However, in the production of chain motors, the frame is basically installed on the iron core one by one by hand, which is time-consuming and labor-intensive, greatly increases the burden on manual labor in the production process, and the production efficiency is very low. At the same time, the overall appearance is not standardized.

[0004] Therefore, it is necessary to improve the existing linear integrated socket frame structure. Utility Model Content

[0005] To address the problems in related technologies, this utility model provides a straight-chain integrated power strip frame structure, which solves the problems of low production efficiency and non-standard appearance.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] The present invention relates to a linear integrated socket frame structure, comprising chain-connected toothed units, each toothed unit being T-shaped, and a frame unit mounted on the toothed unit. The frame unit has a first part and a second part, both of which can be simultaneously fixedly connected to the entire chain-connected toothed unit.

[0008] The above scheme uses a chain-connected toothed unit with a T-shaped structure. The toothed unit is connected to a skeleton, which has a split structure with a first part and a second part. The first part can be connected to the entire toothed unit at the same time, and the second part can also be connected to the entire toothed unit at the same time. That is, only the time required to install one skeleton can be spent to complete the installation of all skeleton units on the toothed unit, which improves the installation efficiency, thereby increasing the slot fill factor of the motor, increasing the power density of the motor, and reducing resistance and loss.

[0009] The first part includes several upper skeletons, and two adjacent upper skeletons are connected as one unit through a first connecting part. The second part includes several lower skeletons, and two adjacent lower skeletons are connected as one unit through a second connecting part. One upper skeleton and one lower skeleton are connected to the same toothed unit at the same time.

[0010] In the above scheme, several upper skeletons are connected as one unit through the first connecting part, and several lower skeletons are connected as one unit through the second connecting part. In this way, the first and second parts can be installed on the toothed unit at one time, thereby enabling the overall installation of the skeleton unit to be completed quickly. At the same time, if the skeleton is installed individually, the position of the skeleton is directly related to the individual toothed unit, which may lead to deformation. In addition, it wastes manpower and resources during the installation process. By connecting the upper and lower skeletons in series through the first and second connecting parts, the relative positions of the first and second parts after being connected to the toothed unit can be more accurate.

[0011] The upper and lower skeletons, which are inserted into the same toothed unit, are welded together.

[0012] Both the upper frame and the upper skeleton of the above scheme are made of insulating materials and can be welded.

[0013] The first connecting part is an upper bent piece, and two adjacent upper skeletons are fixedly connected to the upper bent piece. The second connecting part is a lower bent piece, and two adjacent lower skeletons are fixedly connected to the lower bent piece.

[0014] The upper and lower bending pieces of the above scheme can ensure that multiple upper skeletons are integrated and multiple lower skeletons are integrated. When the upper and lower skeletons are wound into a circle with the toothed unit, the bending parts on the upper and lower bending pieces have a guiding function, which can better form a closed ring and further improve the slot fill factor.

[0015] The toothed unit has an outer limiting part, an inner limiting part, and a winding part. An installation groove is formed between the outer limiting part, the inner limiting part, and the winding part. After the upper frame and the lower frame are installed, they are both in contact with the inner wall of the installation groove.

[0016] The toothed unit in the above scheme is provided with a mounting slot, and the upper and lower skeletons are respectively connected to the mounting slot. Installing the enameled wire through the upper and lower skeletons helps to improve the insulation performance between the enameled wire and the toothed unit.

[0017] The toothed unit adopts a T-shaped iron chip, and the outer limiting parts of two adjacent iron chips are connected as one unit by a connecting part. The inner side of the connecting part is provided with a folding groove, and the outer side of the connecting part is provided with a transition groove to facilitate the bending of the iron chip.

[0018] In the above scheme, the toothed unit can be made of iron chips made of silicon steel sheets. The connecting part of the iron chips is integrally formed, that is, the outer limiting part, the inner limiting part and the winding part are cut out at one time by overlapping silicon steel sheets. The folding groove can be a V-shaped groove, which makes the connection between two connected iron chips tighter and the gap smaller. The transition groove can make the outer surface of the iron chip smoother after it is round, avoiding sharp connection gaps and reducing connection stress.

[0019] The above solution has the following advantages:

[0020] A straight-chain integrated power strip frame structure includes chain-connected toothed units, each toothed unit being T-shaped, and a frame unit mounted on the toothed unit. The frame unit has a first part and a second part, both of which can be fixedly connected to the entire chain-connected toothed unit simultaneously.

[0021] 1. The linear integrated socket frame structure of the present invention includes chain-connected toothed units, each toothed unit being T-shaped, and a frame unit mounted on the toothed unit. The frame unit has a first part and a second part, both of which can be simultaneously fixedly connected to the entire chain-connected toothed unit. Since the toothed unit is a T-shaped structure, and the frame is connected to the toothed unit, the frame adopts a split structure, having a first part and a second part. The first part can be simultaneously connected to the entire toothed unit, and the second part can also be simultaneously connected to the entire toothed unit. That is, only the time previously spent installing one frame is required to complete the installation of all frame units on the toothed unit, improving installation efficiency, thereby increasing the slot fill factor of the motor, increasing the power density of the motor, and reducing resistance and losses.

[0022] 2. The first section includes several upper skeletons, with adjacent upper skeletons connected together by a first connecting part. The second section includes several lower skeletons, with adjacent lower skeletons connected together by a second connecting part. One upper skeleton and one lower skeleton are connected to the same toothed unit simultaneously. Several upper skeletons are connected together by the first connecting part, and several lower skeletons are connected together by the second connecting part. In this way, the first and second sections can be installed on the toothed unit at one time, thus enabling the overall installation of the skeleton unit to be completed quickly. At the same time, if the skeleton is installed individually, the position of the skeleton is directly related to the individual toothed unit, which may lead to deformation. It also wastes manpower and resources during the installation process. By connecting the upper and lower skeletons in series by the first and second connecting parts, the relative positions of the first and second sections after being connected to the toothed unit can be more accurate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 As shown, the first embodiment of the linear integrated socket frame structure includes chain-connected toothed units 1, each toothed unit 1 being T-shaped, and a frame unit 2 mounted on the toothed unit 1. Each frame unit 2 has a first part and a second part, both of which can be simultaneously fixedly connected to the entire chain-connected toothed unit 1. The chain-connected toothed unit 1 is T-shaped, and a frame is connected to the toothed unit 1. The frame unit 2 adopts a split structure, having a first part and a second part. The first part can be simultaneously connected to the entire toothed unit 1, and the second part can also be simultaneously connected to the entire toothed unit 1. That is, only the time previously spent installing one frame is needed to complete the installation of all frame units 2 on the toothed unit 1, improving installation efficiency and thus increasing the slot fill factor of the motor, increasing the power density of the motor, and reducing resistance and losses.

[0032] Furthermore, the toothed unit 1 adopts a T-shaped iron chip structure. The outer limiting portions 101 of two adjacent iron chips are connected as one piece by a connecting portion. The inner side of the connecting portion is provided with a fold-back groove 3, and the outer side of the connecting portion is provided with a transition groove 4 to facilitate the bending of the iron chip. Based on this, the toothed unit 1 of this embodiment can adopt iron chips made of stacked silicon steel sheets. The connecting portion of the iron chip is integrally formed, that is, the outer limiting portion 101, the inner limiting portion 103, and the winding portion 102 are cut out at one time from the stacked silicon steel sheets. The fold-back groove 3 can be a V-shaped groove, which makes the connection between the two connected iron chips tighter and the gap smaller. The transition groove 4 can make the outer surface of the iron chip smoother after it is rounded, avoiding sharp connection gaps and reducing connection stress.

[0033] like Figure 3 As shown, the toothed unit 1 of this embodiment has an outer limiting part 101, an inner limiting part 103, and a winding part 102. A mounting groove is formed between the outer limiting part 101, the inner limiting part 103, and the winding part 102. After installation, the upper skeleton 201 and the lower skeleton 202 are both in contact with the inner wall of the mounting groove. The toothed unit 1 is provided with a mounting groove, and the upper skeleton 201 and the lower skeleton 202 are respectively connected to the mounting groove. The installation of the enameled wire through the upper and lower skeletons 202 increases the creepage distance between the enameled wire and the iron core, which is beneficial to improving the insulation performance between the enameled wire and the toothed unit 1.

[0034] Specifically, the first part of the skeleton unit 2 includes several upper skeletons 201, with adjacent upper skeletons 201 connected together by a first connecting part; the second part includes several lower skeletons 202, with adjacent lower skeletons 202 connected together by a second connecting part, such as... Figure 1 or Figure 2 or Figure 5 As shown, the first connecting part in this embodiment is an upper bent piece 203, and two adjacent upper skeletons 201 are fixedly connected to the upper bent piece 203. The second connecting part is a lower bent piece 204, and two adjacent lower skeletons 202 are fixedly connected to the lower bent piece 204. In addition, one upper skeleton 201 and one lower skeleton 202 are connected to the same toothed unit 1 at the same time. It can be seen that several upper skeletons 201 are connected into one body through the first connecting part, and several lower skeletons 202 are connected into one body through the second connecting part. The number of upper skeletons 201 and lower skeletons 202 is the same as the number of toothed units 1. When installing an upper skeleton 201 or a lower skeleton 202, it is necessary to install all upper skeletons 201 or lower skeletons 202 on the toothed unit 1 at the same time. In this way, the first part and the second part can be installed on the toothed unit 1 at one time, so that the overall installation of the skeleton unit 2 can be completed quickly. After the skeleton unit 2 is installed, the skeleton unit 2 and the toothed unit 1 are fixedly connected by installing the wound enameled wire.

[0035] It should be noted that if the skeleton is installed manually one by one, the position of the skeleton is directly related to the individual toothed unit 1, which may result in deformation or uneven appearance. Moreover, the installation process often wastes manpower and resources. By connecting the upper skeleton 201 and the lower skeleton 202 in series through the first connecting part and the second connecting part, the relative position of the first part and the second part after connecting with the toothed unit 1 can be more accurate.

[0036] like Figure 4 As shown, in the second embodiment of the straight-chain integrated socket frame structure, compared with the first embodiment, the upper frame 201 and the lower frame 202, which are inserted on the same toothed unit 1, are welded together. In this embodiment, both the upper frame 201 and the lower frame 202 are made of insulating material and can be welded.

[0037] The upper bending piece 203 and lower bending piece 204 of the first and second embodiments described above can ensure that multiple upper skeletons 201 are integrated and multiple lower skeletons 202 are integrated. When the upper and lower skeletons 202 are wound into a circle with the toothed unit 1, the bending parts on the upper bending piece 203 and lower bending piece 204 have a guiding function, which can better form a closed ring and further improve the slot fill factor.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
