Description

Technical Field

[0001] This utility model relates to the field of electric motors, and in particular to an electric motor with a modular installation structure. Background Technology

[0002] Compared to the traditional rotary motor + mechanical conversion mechanism drive method, the linear motor direct drive system can directly convert electrical energy into linear motion mechanical energy without the need for an intermediate mechanical conversion mechanism. This improves the efficiency, reliability, and control precision of the drive system, making it suitable for linear motion applications.

[0003] Existing technology (patent document with publication number "CN223007470U") discloses a modular motor, comprising multiple mover modules and stator modules sequentially assembled along the mover's direction of motion. Each mover module includes a mover base plate and multiple permanent magnets. Multiple mover protrusions are arranged around one set of adjacent sidewalls of the mover base plate, and multiple mover grooves are arranged around another set of adjacent sidewalls to allow adjacent mover modules to engage and be fixed. Each stator module includes a stator base plate, multiple stator cores, and multiple armature coils. Each stator core is spaced apart at the top of the stator base plate along the mover's direction of motion. Each armature coil is wound around a stator core. Multiple stator protrusions are arranged around one set of adjacent sidewalls of the stator base plate, and multiple stator grooves are arranged around another set of adjacent sidewalls to allow adjacent stator modules to engage and be fixed. This modular motor allows for flexible assembly of the mover and stator modules, and flexible adjustment of the motor's maximum load capacity.

[0004] Based on the above search and combined with existing technology, it was found that although existing modular motors (electric motors) have the function of modular splicing, their vertical reverse limiting effect during splicing is poor. The motor may be vertically displaced during operation, causing multiple moving sub-modules or multiple stator modules that are spliced ​​to form the motor to disintegrate, resulting in poor reliability. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The core of this invention lies in solving the problem of poor vertical reverse limiting effect and potential vertical displacement of the motor during operation in existing technologies by using the insertion and engagement of slots and plugs, and by using limiting wedges to lock and limit the plugs. Simultaneously, the detachable design allows for easy disassembly of multiple moving sub-modules or multiple stator modules for flexible adjustment.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An electric motor with a modular installation structure includes multiple mover modules and multiple stator modules that are sequentially spliced ​​along a preset mover movement direction or along a direction perpendicular to the mover movement direction, and each of the multiple mover modules and multiple stator modules includes a splicing plate;

[0010] The splicing panel has slots on both sides of the adjacent sidewalls. The splicing panel and the slots have inserts on the other two sides of the sidewalls. The inserts are fitted into the slots. The slots are trapezoidal grooves that are narrow on the inside and wide on the outside. The inserts are trapezoidal blocks.

[0011] The splicing plate has a vertically extending groove that connects the slot to the outside of the splicing plate, and the extension direction of the groove is perpendicular to the opening of the slot.

[0012] A connecting rod is detachably fixed on the splicing plate. The bottom of the connecting rod is elastically connected to a limit wedge through a compression spring. The limit wedge is slidably embedded in the groove and its lower end extends into the slot. The side of the limit wedge facing the slot opening forms an arc-shaped inclined sidewall. A groove for the limit wedge to be inserted is provided on the insert block.

[0013] A limiting structure is also formed on the connecting rod and the limiting wedge. The limiting structure is used to limit the travel of the limiting wedge to the side away from the connecting rod, so that the upper end of the limiting wedge will not fall off the slide groove.

[0014] By modifying the existing dovetail groove and dovetail block engagement into a slot and plug engagement, and using a limiting wedge to engage and limit the plug, the plug cannot be separated after being inserted into the slot. This makes the splicing of adjacent splicing plates stable and reliable, and achieves the goal of making it difficult for multiple moving sub-modules and multiple stator modules to detach in both the horizontal and vertical directions after splicing, thereby improving the overall structural stability and reliability of the modular motor.

[0015] When disassembly is required, simply remove the connecting rod to separate it from the splicing plate, and then pull out the limiting wedge. This will cause the limiting wedge to lose its limiting effect on the insert, making it convenient to disassemble multiple moving sub-modules or multiple stator modules for flexible adjustment.

[0016] Furthermore, the top of the splicing panel is provided with a long groove, which is connected to the sliding groove. The connecting rod is movably embedded in the long groove, and the top of the connecting rod is on the same plane as the top of the splicing panel.

[0017] Furthermore, the limiting structure includes a limiting guide rod, which is fixed to the top of the limiting wedge block. The upper end of the limiting guide rod slides through the connecting rod and is integrally formed with a guide rod limiting plate. The guide rod limiting plate is movably embedded in the connecting rod and its lower end is connected to the top of the connecting rod. A compression spring is movably sleeved on the limiting guide rod.

[0018] Furthermore, the top of the splicing plate is also provided with a limiting groove that is connected to the long embedded groove at the top. The limiting groove and the slot are staggered. The limiting groove is a fan-shaped groove in plan view. A countersunk screw is rotatably embedded on the connecting rod. The top of the countersunk screw and the top of the connecting rod are on the same plane. A fixing block is fixed at the lower end of the countersunk screw through a short shaft. The diameter of the short shaft is smaller than the diameter of the countersunk screw. The fixing block is located below the connecting rod and is rotatably embedded in the limiting groove.

[0019] The countersunk bolt has a socket at the top.

[0020] Optionally, the limiting structure includes a wedge limiting plate, which is fixed to the top of the limiting wedge. The length of the wedge limiting plate is greater than the length of the limiting wedge. The length of the slide groove is the same as the length of the wedge limiting plate. A shrinkage hole with the same length as the limiting wedge is formed at the opening where the slide groove connects to the slot.

[0021] Furthermore, the connecting rod cross-section is a trapezoid with a wider top and a narrower bottom. The long groove is adapted to the shape of the connecting rod. A notch is opened at the top of the long groove, and a limiting frame is fitted on the notch. The limiting frame is fixed to the splicing plate by countersunk hexagonal bolts. An annular notch is opened on the splicing plate, which communicates with the opening of the long groove and allows the limiting frame to be inserted. The tops of the limiting frame and the countersunk hexagonal bolts are both located in the same plane as the top of the splicing plate.

[0022] 3. Beneficial Effects

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] (1) This solution improves the existing dovetail groove and dovetail block matching by using slot and plug matching, and uses limit wedge to lock and limit the plug, so that the plug cannot be separated after being inserted into the slot, thereby making the splicing of adjacent splicing plates stable and reliable, achieving the purpose of making it difficult for multiple moving sub-modules and multiple stator modules to separate in both horizontal and vertical directions after splicing, thus improving the overall structural stability and reliability of the modular motor.

[0025] (2) This solution is designed to be detachable. When multiple moving sub-modules or multiple stator modules need to be disassembled, the connecting rod can be disassembled to separate it from the splicing plate, and the limiting wedge can be pulled out, so that the limiting wedge loses its limiting function on the insert block, making it convenient to disassemble multiple moving sub-modules or multiple stator modules for flexible adjustment.

Detailed Implementation

[0037] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0038] Example 1: Please refer to Figures 1-5 An electric motor with a modular installation structure includes multiple mover modules 100 and multiple stator modules 200 sequentially spliced ​​along a preset mover movement direction or along a direction perpendicular to the mover movement direction, and each of the multiple mover modules 100 and multiple stator modules 200 includes a splicing plate 1.

[0039] The splicing panel 1 has slots 11 on both sides of its adjacent sidewalls. The splicing panel 1 and the slots 11 have inserts 12 integrally formed on the other two sidewalls. The inserts 12 are inserted into and matched with the slots 11. The slots 11 are trapezoidal slots that are narrow on the inside and wide on the outside, and the inserts 12 are trapezoidal blocks.

[0040] A vertically extending groove 15 is provided on the splicing plate 1. The groove 15 connects the slot 11 and the outside of the splicing plate 1, and the extending direction of the groove 15 is perpendicular to the opening direction of the slot 11.

[0041] A connecting rod 3 is detachably fixed on the splicing plate 1. The bottom of the connecting rod 3 is elastically connected to the limiting wedge 2 through the compression spring 4. The limiting wedge 2 is slidably embedded in the slide groove 15 and its lower end extends into the slot 11. The side of the limiting wedge 2 facing the opening of the slot 11 forms an arc-shaped inclined sidewall. The insert 12 has a groove for the limiting wedge 2 to be inserted.

[0042] A limiting structure is also formed on the connecting rod 3 and the limiting wedge 2. The limiting structure is used to limit the travel of the limiting wedge 2 to the side away from the connecting rod 3, so that the upper end of the limiting wedge 2 will not disengage downward from the slide groove 15.

[0043] Based on the above structure, when multiple moving sub-modules 100 or multiple stator modules 200 need to be spliced, only the corresponding splicing plates 1 need to be spliced. During the splicing of two splicing plates 1, when the insert block 12 is inserted into the slot 11, it abuts against the arc-shaped inclined side wall of the limiting wedge block 2, so that the limiting wedge block 2 overcomes the elastic force of the compression spring 4 and moves upward. When the insert block 12 is fully inserted into the slot 11, the limiting wedge block 2 descends under the elastic force of the compression spring 4 and inserts into the groove on the insert block 12, thereby limiting the insert block 12, so that the insert block 12 cannot be separated after being inserted into the slot 11 (under the limiting wedge block 2), thus making the splicing of adjacent splicing plates 1 stable and reliable, achieving the purpose that multiple moving sub-modules 100 and multiple stator modules 200 are not easy to separate in the horizontal and vertical directions after splicing, improving the overall structural stability and reliability of the modular motor;

[0044] When disassembly is required, simply disassemble the connecting rod 3 to separate it from the splicing plate 1, and then pull out the limiting wedge 2. This will cause the limiting wedge 2 to lose its limiting effect on the insert block 12, making it convenient to disassemble multiple moving sub-modules 100 or multiple stator modules 200 for flexible adjustment.

[0045] It should be noted that a single moving module 100 and a single stator module 200 should also include other structures besides the splicing plate 1, such as the permanent magnet that makes up the moving module 100, the stator core (including the main core teeth, isolation core teeth, and end core teeth) that makes up the stator module 200, the armature coil, etc. Their specific structures, connections, and working principles are all existing technologies and will not be described in detail here.

[0046] Furthermore, the top of the splicing plate 1 is provided with a long groove 13, which is connected to the sliding groove 15. The connecting rod 3 is movably embedded in the long groove 13, and the top of the connecting rod 3 is on the same plane as the top of the splicing plate 1. This can prevent the connecting rod 3 from being directly exposed outside the splicing plate 1, reduce the probability of the connecting rod 3 being deviated by external forces, and ensure the stability of the installation of the connecting rod 3.

[0047] Furthermore, the limiting structure includes a limiting guide rod 5, which is fixed to the top of the limiting wedge 2. The upper end of the limiting guide rod 5 slides through the connecting rod 3 and is integrally formed with a guide rod limiting plate 51. The guide rod limiting plate 51 is movably embedded on the connecting rod 3 and its lower end is connected to the top of the connecting rod 3. The compression spring 4 is movably sleeved on the limiting guide rod 5. The guide rod limiting plate 51 can limit the limiting wedge 2, so that when it is affected by the elastic force of the compression spring 4, its upper end stays in the slide groove 15, thereby avoiding the disadvantage of the limiting wedge 2 entering the slot 11 and becoming difficult to remove.

[0048] Furthermore, the top of the splicing plate 1 is also provided with a limiting groove 14 that is connected to the long embedded groove 13 at the top. The limiting groove 14 and the slot 11 are staggered. The limiting groove 14 is a groove with a fan-shaped top section. A countersunk bolt 7 is rotatably embedded on the connecting rod 3. The top of the countersunk bolt 7 is on the same plane as the top of the connecting rod 3. A fixing block 6 is fixed at the lower end of the countersunk bolt 7 through a short shaft. The diameter of the short shaft is smaller than the diameter of the countersunk bolt 7. The fixing block 6 is located below the connecting rod 3 and is rotatably embedded in the limiting groove 14.

[0049] The countersunk bolt 7 has a socket 71 at its top.

[0050] When installing the connecting rod 3, first insert the connecting rod 3 into the long groove 13, and insert the limiting wedge 2 into the sliding groove 15. At the same time, rotate the fixing block 6 so that its length is opposite to the length direction of the connecting rod 3, so that the fixing block 6 retracts below the connecting rod 3, making it easier for the fixing block 6 to be inserted into the limiting groove 14. Then, insert the tool (a plug plate or plug-in knob, etc. that is compatible with the socket 71) into the socket 71, and rotate the countersunk screw 7 to drive the fixing block 6 to rotate, so that the fixing block 6 rotates to the vertical position of the connecting rod 3 and is inserted into the limiting groove 14 to fix the connecting rod 3.

[0051] When it is necessary to remove the connecting rod 3, simply rotate the countersunk bolt 7 in the opposite direction so that the fixing block 6 rotates again to be in the same direction as the connecting rod 3. The operation is convenient.

[0052] Example 2: Please refer to Figure 1 , Figures 6-8 An electric motor with a modular mounting structure, which differs from Embodiment 1 in that:

[0053] The limiting structure includes a wedge limiting plate 21, which is fixed to the top of the limiting wedge 2. The length of the wedge limiting plate 21 is greater than the length of the limiting wedge 2. The length of the slide groove 15 is the same as the length of the wedge limiting plate 21. The opening of the slide groove 15, which connects to the slot 11, forms a constriction hole with the same length as the limiting wedge 2. By setting the wedge limiting plate 21, when the limiting wedge 2 slides down, the wedge limiting plate 21 abuts against the top of the constriction hole at the lower end of the slide groove 15, thereby limiting the limiting wedge 2 and keeping the upper end of the limiting wedge 2 in the slide groove 15, thus preventing the limiting wedge 2 from being completely inserted into the slot 11 and difficult to remove.

[0054] Furthermore, the cross-section of the connecting rod 3 is a trapezoid with a wider top and a narrower bottom. The long groove 13 is adapted to the shape of the connecting rod 3. A notch 31 is opened at the top of the long groove 13. A limiting frame 8 is fitted on the notch 31. The limiting frame 8 is fixed to the splicing plate 1 by countersunk hexagonal bolts 9. An annular notch is opened on the splicing plate 1, which communicates with the opening of the long groove 13 and allows the limiting frame 8 to be inserted. The tops of the limiting frame 8 and the countersunk hexagonal bolts 9 are both located in the same plane as the top of the splicing plate 1.

[0055] With the setting of the limiting frame 8 and the countersunk hexagon socket bolt 9, after the connecting rod 3 is embedded in the long groove 13, the user only needs to insert the limiting frame 8 into the notch 31 and the annular notch on the splicing plate 1, and then fix the limiting frame 8 with the countersunk hexagon socket bolt 9 to limit the connecting rod 3. The operation is equally convenient and will not damage the structure of the connecting rod 3, thus ensuring the strength of the connecting rod 3.

[0056] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
