Description

Technical Field

[0001] This utility model belongs to the field of permanent magnet synchronous motor technology, and in particular relates to a quick-assembly permanent magnet synchronous motor housing structure. Background Technology

[0002] Traditional permanent magnet synchronous motor housings mostly adopt an integral casting or welding structure, and are usually designed into multiple modules, such as: upper cover, lower cover and end cover. This design makes it convenient for staff to install, maintain and repair permanent magnet synchronous motors.

[0003] Currently, when installing the end cover of a permanent magnet synchronous motor, multiple workers are often required to align the mounting holes on the end cover flange ring with the mounting holes on the housing flange ring before bolts can be used for fixing. This method is time-consuming and requires multiple workers, which leads to reduced production efficiency. To address this, we propose a rapid assembly permanent magnet synchronous motor housing structure. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly permanent magnet synchronous motor housing structure. By setting a locking assembly, specifically by moving the end cover to the right, allowing the three L-shaped locking rods on its right side to enter the three slots within flange one, and then rotating the end cover clockwise to move the L-shaped locking rods into slot two, the end cover and flange one are initially fixed. Bolts are then inserted into the mounting holes of flange one and flange two and tightened. For disassembly, the bolts on both flanges are unscrewed, and the end cover is rotated counterclockwise to disengage the L-shaped locking rods from slot two, allowing the end cover to be removed. This method allows for single-person installation, eliminating the need for multiple workers, significantly improving production efficiency. It solves the problem that existing methods for disassembling and assembling the end cover of permanent magnet synchronous motors require multiple workers, leading to a significant reduction in production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a quick-assembly permanent magnet synchronous motor housing structure, comprising a permanent magnet synchronous motor, the permanent magnet synchronous motor including an upper cover and a lower cover, the rotor being installed inside the lower cover, an end cover being provided on the left side of the permanent magnet synchronous motor, and further comprising:

[0007] A locking assembly, mounted on the right side of the end cap, for securing the end cap to the upper and lower caps; and

[0008] A positioning component is installed at the bottom and left side of the upper cover, and the positioning component is used to quickly position the upper cover and the lower cover.

[0009] Furthermore, the locking assembly includes a first flange, which is fixedly connected to the left side of the lower cover, and a second flange, which is fixedly connected to the right side of the end cover. Three L-shaped locking rods are fixedly connected to the right side of the second flange.

[0010] Furthermore, the flange has three slots inside, and each slot has a second slot. The end cap is rotatably connected to the three slots inside the flange via three L-shaped locking rods on its right side.

[0011] Furthermore, both flange one and flange two have several mounting holes inside, and the mounting holes inside flange one and flange two correspond one-to-one.

[0012] Furthermore, the positioning component includes four positioning blocks, all of which are fixedly connected to the bottom of the upper cover. The lower cover has two positioning slots inside, and the positioning blocks are inserted into the positioning slots.

[0013] Furthermore, a plug block is fixedly connected to the left side of the upper cover, and a slot is provided inside the flange, with the plug block being inserted into the slot.

[0014] Furthermore, both the upper and lower covers have several mounting holes on their sides, and the mounting holes on both sides of the upper and lower covers correspond one-to-one.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a locking assembly. Specifically, the end cover is moved to the right, causing the three L-shaped locking rods on its right side to enter the three slots within the flange. The end cover is then rotated clockwise to allow the L-shaped locking rods to enter the slots, thus initially fixing the end cover to the flange. Bolts are then inserted into the mounting holes of flanges one and two and tightened. For disassembly, the bolts on both flanges are unscrewed, and the end cover is rotated counterclockwise to allow the L-shaped locking rods to leave the slots, allowing the end cover to be removed. This method allows for installation by a single worker, eliminating the need for multiple workers and significantly improving production efficiency.

[0017] 2. This utility model uses a positioning component. Specifically, the rotor is placed in the cavity of the lower cover, and then the four positioning blocks at the bottom of the upper cover are simultaneously inserted into the two positioning slots inside the lower cover. When the upper cover is moved, the insert block on its left side will be inserted into the slot. The upper and lower covers are quickly positioned by the cooperation of the positioning blocks, positioning slots, and insert block with the slot. Then, the bolts are placed into several mounting holes on both sides of the upper and lower covers and tightened. This method enables the upper and lower covers to be quickly positioned, which facilitates the subsequent bolt installation work.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 As shown, this utility model is a quick-assembly permanent magnet synchronous motor housing structure, including a permanent magnet synchronous motor 1. The permanent magnet synchronous motor 1 includes an upper cover 11 and a lower cover 12. A rotor 13 is installed inside the lower cover 12. An end cover 14 is provided on the left side of the permanent magnet synchronous motor 1. It also includes:

[0028] Locking component 2, mounted on the right side of end cover 14, is used to secure end cover 14 to upper cover 11 and lower cover 12; and

[0029] Positioning component 3 is installed at the bottom and left side of the upper cover 11. Positioning component 3 is used to quickly position the upper cover 11 and the lower cover 12.

[0030] The locking assembly 2 includes a first flange 21, which is fixedly connected to the left side of the lower cover 12. A second flange 22 is fixedly connected to the right side of the end cover 14, and three L-shaped locking rods 23 are fixedly connected to the right side of the second flange 22.

[0031] The flange 11 has three slots 24 inside, and slots 25 are formed inside slots 24. The end cover 14 is rotatably connected to the three slots 25 inside the flange 11 via three L-shaped locking rods 23 on its right side.

[0032] Both flange 1 (21) and flange 2 (22) have several mounting holes inside, which correspond one-to-one. The end cover 14 is moved to the right, causing the three L-shaped locking rods 23 on its right side to enter the three slots 24 inside flange 1 (21). The end cover 14 is then rotated clockwise to allow the L-shaped locking rods 23 to enter slots 25, completing the initial fixation of the end cover 14 to flange 1 (21). Bolts are then inserted into the mounting holes of flange 1 (21) and flange 2 (22) and tightened. For disassembly, the bolts on both flanges are unscrewed, and the end cover 14 is rotated counterclockwise to disengage the L-shaped locking rods 23 from slots 25, allowing the end cover 14 to be removed. This method allows for single-person installation, eliminating the need for multiple workers and significantly improving production efficiency.

[0033] The positioning component 3 includes four positioning blocks 31, all of which are fixedly connected to the bottom of the upper cover 11. The lower cover 12 has two positioning grooves 32 inside, and the positioning blocks 31 are inserted into the positioning grooves 32.

[0034] The left side of the top cover 11 is fixedly connected to the insert block 33, and the flange 21 has a slot 34 inside, and the insert block 33 is inserted into the slot 34.

[0035] Both the upper cover 11 and the lower cover 12 have several mounting holes on their sides, and the mounting holes on the upper cover 11 and the lower cover 12 correspond one-to-one. The rotor 13 is placed in the cavity of the lower cover 12. Then, the four positioning blocks 31 at the bottom of the upper cover 11 are simultaneously inserted into the two positioning grooves 32 inside the lower cover 12. When the upper cover 11 is moved, the first insertion block 33 on its left side will be inserted into the slot 34. The upper cover 11 and the lower cover 12 are quickly positioned by the cooperation of the positioning blocks 31, the positioning grooves 32, and the first insertion block 33 with the slot 34. Then, the bolts are put into the several mounting holes on both sides of the upper cover 11 and the lower cover 12 and tightened. This method can quickly position the upper cover 11 and the lower cover 12, which is convenient for the subsequent bolt installation work.

[0036] A specific application of this embodiment is as follows: When in use, the rotor 13 is first placed in the cavity of the lower cover 12, and then the four positioning blocks 31 at the bottom of the upper cover 11 are simultaneously inserted into the two positioning slots 32 inside the lower cover 12. When the upper cover 11 is moved, the first insertion block 33 on its left side will also be inserted into the slot 34. The cooperation of the positioning blocks 31, positioning slots 32, and the first insertion block 33 with the slot 34 enables the upper cover 11 and the lower cover 12 to be quickly positioned, which facilitates the subsequent installation work. Then, the bolts are inserted one by one into the several mounting holes on both sides of the upper cover 11 and the lower cover 12, and tightened one by one with a wrench.

[0037] Then move the end cap 14 to the right so that the three L-shaped locking rods 23 on its right side simultaneously enter the three slots 24 in the flange 21. Then rotate the end cap 14 clockwise so that the L-shaped locking rods 23 enter the slots 25. At this time, the end cap 14 is fixed to the flange 21. Then insert the bolts into the mounting holes in the flange 21 and flange 22 respectively, and tighten them one by one with a wrench.

[0038] When it is necessary to disassemble the permanent magnet synchronous motor 1 for maintenance and repair, use a wrench to unscrew the bolts on flange 1 21 and flange 2 22 one by one. Then, rotate the end cover 14 counterclockwise to make the L-shaped locking rod 23 disengage from the slot 2 25. After that, remove the end cover 14. Then, use a wrench to unscrew several bolts on both sides of the upper cover 11 and the lower cover 12. Finally, pull out the upper cover 11.
