Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to driving micro motors. Background Technology

[0002] Micro motors, also known as micro-motors or micro electric motors, include asynchronous micro motors and synchronous micro motors. Currently, various types of actuators use micro motors as power sources. Examples include pneumatic actuators and hydraulic actuators. These actuators have different characteristics and advantages depending on the application scenario.

[0003] Utility model patent CN213072260U discloses an improved micro motor. This improved micro motor includes a base, an outer shell, an inner shell, a rear cover, and a front cover. The outer shell is located at the upper end of the base, and the inner shell is located inside the outer shell. The front cover is fixedly installed at one end of the outer shell, and the rear cover is fixedly installed at the end of the outer shell away from the front cover. Magnets are fixedly installed on both sides of the inner shell. A fixing seat is provided at one end of the inner wall of the outer shell, and an upper clamping washer and a lower clamping washer are provided on the inner wall of the outer shell away from the fixing seat. One end of the magnet is inserted into the fixing seat, and the other end is inserted between the upper and lower clamping washer for fixed installation. The outer shell and inner shell protect the iron core. By installing the iron core inside the inner shell and then sealing the inner shell with the outer shell, the iron core is safely preserved. Simultaneously, the use of fixing bolts, the front cover, the rear cover, the front fixing plate, and the rear fixing plate allows for quick disassembly and installation of the front and rear covers, facilitating the disassembly and maintenance of the micro motor. By providing a fixing seat, an upper clamping pad, and a lower clamping pad at each end of the magnetic tile, the magnetic tile is fixedly installed inside the outer casing, solving the problem of the traditional method of bonding the magnetic tile and the outer casing with glue. This design is more secure, easier to use, and improves the stability of the magnetic tile.

[0004] Although the improved micro motor has the advantage of reliable installation, the device still has the following problems in actual use: When installing the outer shell, the device achieves quick disassembly and installation of the front and rear covers through the cooperation of the fixed bolts and the front and rear fixed plates. However, this design requires the use of a screwdriver to remove and install multiple fixed bolts when disassembling and installing the front and rear covers. Since the micro motor is small, removing and installing multiple bolts is time-consuming and laborious, which increases the difficulty of disassembling and installing the front and rear covers. In view of this, we propose a drive micro motor. Utility Model Content

[0005] To solve the above problems, this utility model provides a driving micro motor.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A micro motor is driven, including a housing. The left and right side walls of the housing are fixed with housings at the front and rear ends. A connecting groove is opened at the two opposite ends of two adjacent housings. A strip groove is opened on one side of the connecting groove.

[0008] The groove has two movable blocks that can move horizontally installed on both sides. Two limit plates are fixed on the two opposite ends of the two movable blocks. The ends of the movable blocks are inserted into the groove. A double-ended screw is rotatably installed in the groove, and the two movable blocks are threaded to the threaded grooves at both ends of the double-ended screw.

[0009] The front and rear ends of the casing are respectively equipped with a front cover and a rear cover. A connecting bracket is fixed on each of the two opposite ends of the front cover and the rear cover. The connecting bracket is inserted into the connecting groove. A groove is opened at the connecting bracket. The movable block is inserted into the groove and abuts against the inner wall of the groove. Two limiting grooves are opened on the upper and lower walls of the groove. The limiting plate is inserted into the corresponding limiting groove.

[0010] Furthermore, the overall shape of the connecting frame is U-shaped, and the connecting frame is fixedly connected to the front cover and the rear cover by bolts.

[0011] Furthermore, the overall shape of the movable block is rectangular, and the size of the movable block is adapted to the size of the connecting groove.

[0012] Furthermore, the movable block and the limiting plate are integrally formed, with the limiting plate perpendicular to the movable block.

[0013] Furthermore, a sealing sleeve is fixed to each of the two opposing end faces of the front cover and the rear cover. The sealing sleeve has a U-shaped cross-section and its size is matched with the opening of the housing.

[0014] Furthermore, two inclined support plates are fixed to the bottom of the housing, and a mounting plate is fixed between the bottom ends of the two support plates. Two mounting holes are opened at both ends of the mounting plate.

[0015] Furthermore, the threaded grooves at both ends of the double-ended lead screw have opposite threading directions, and the top end of the double-ended lead screw passes through the housing and is coaxially keyed to an adjusting head.

[0016] Furthermore, a partition is fixed at the center of the connecting groove, and a double-ended lead screw passes through the partition and is rotatably connected to the partition via a bearing.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The design incorporates a housing, movable blocks, and limiting plates. Connecting brackets are installed at both the front and rear covers. These brackets are inserted into the housing, and the limiting plates, in conjunction with their corresponding grooves, connect and secure the front and rear covers to the housing. To remove the front and rear covers, rotating the double-ended screw disengages the limiting plate from the groove, allowing the covers to be removed. This design eliminates the need to disassemble bolts or other connecting parts, increasing the ease of installation and removal, and consequently improving the maintenance convenience of the micro motor.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] This embodiment provides a technical solution:

[0031] Please see Figures 1-4As shown, the driving micro motor includes a housing 1. Housings 12 are fixed to the left and right side walls at the front and rear ends of the housing 1. Connecting grooves 120 are formed at the two opposite ends of two adjacent housings 12. A strip groove 121 is formed on one side of each connecting groove 120. Horizontally movable blocks 15 are installed on both sides of the strip groove 121. Two limiting plates 16 are fixed to the two opposite ends of each movable block 15. The ends of the movable blocks 15 pass through the strip groove 121. A rotating part is rotatably mounted within the strip groove 121. A double-ended lead screw 13 is provided, and two movable blocks 15 are threadedly connected to the threaded grooves at both ends of the double-ended lead screw 13. A front end cover 2 and a rear end cover 3 are respectively installed at the front and rear ends of the housing 1. A connecting bracket 4 is fixed on one of the two opposing end faces of the front end cover 2 and the rear end cover 3. The connecting bracket 4 is inserted into the connecting groove 120. A groove 40 is provided at the connecting bracket 4. The movable block 15 is inserted into the groove 40 and abuts against the inner wall of the groove 40. Two limiting grooves 41 are provided on the upper and lower walls of the groove 40. The limiting plate 16 is inserted into the corresponding limiting groove 41.

[0032] In this embodiment, the connecting frame 4 has an overall U-shaped shape and is fixedly connected to the front cover 2 and the rear cover 3 by bolts. The U-shaped connecting frame 4 has better structural strength and facilitates its insertion into the connecting groove 120. The bolt fixing method ensures the reliable connection between the connecting frame 4 and the front cover 2 and the rear cover 3.

[0033] In this embodiment, the movable block 15 has a rectangular shape, and its dimensions are adapted to the dimensions of the connecting groove 120. This design facilitates the stable horizontal movement of the movable block 15 within the connecting groove 120, preventing the movable block 15 from wobbling.

[0034] In this embodiment, the movable block 15 and the limiting plate 16 are integrally formed, with the limiting plate 16 perpendicular to the movable block 15. The integrally formed movable block 15 and limiting plate 16 have better connection strength, ensuring the reliable connection and service life of the movable block 15 and the limiting plate 16.

[0035] In this embodiment, sealing sleeves 5 are fixed to the two opposing end faces of the front cover 2 and the rear cover 3. The cross-sectional shape of the sealing sleeves 5 is U-shaped, and the size of the sealing sleeves 5 is inserted and fitted into the opening of the housing 1. The sealing sleeves 5 increase the sealing performance between the front cover 2 and the rear cover 3 and the housing 1.

[0036] In this embodiment, two inclined support plates 10 are fixed to the bottom of the housing 1, and a mounting plate 11 is fixed between the bottom ends of the two support plates 10. Two mounting holes are provided at both ends of the mounting plate 11. This design facilitates the mounting of the housing 1 to a fixed platform using bolts.

[0037] In this embodiment, the threaded grooves at both ends of the double-ended lead screw 13 have opposite threading directions. The top end of the double-ended lead screw 13 passes through the housing 12 and is coaxially keyed to an adjusting head 14. Rotating the adjusting head 14 facilitates the rotation of the double-ended lead screw 13, improving the convenience and smoothness of operation. Because the threaded grooves at both ends of the double-ended lead screw 13 have opposite threading directions, the movable blocks 15 on both sides can move synchronously relative to each other when the double-ended lead screw 13 rotates, thereby facilitating the insertion or disengagement of the limiting plate 16 from the limiting groove 41.

[0038] In this embodiment, a partition plate 122 is fixed at the center of the connecting groove 120, and the double-ended lead screw 13 passes through the partition plate 122 and is rotatably connected to the partition plate 122 via a bearing. The partition plate 122 supports the double-ended lead screw 13 and also limits the movement of the movable block 15.

[0039] It should be added that, in this embodiment, the housing 12 is fixedly connected to the outer wall of the housing 1 by bolts. The bolt fixing method has the advantages of reliable connection and easy assembly. This design improves the connection stability between the housing 12 and the housing 1, and at the same time improves the assembly convenience between the housing 12 and the housing 1.

[0040] In practical use, the user first rotates the adjusting head 14, which drives the double-ended lead screw 13 to rotate. Since the movable block 15 is threadedly connected to the double-ended lead screw 13, the movable blocks 15 on both sides move synchronously toward the center. The movable blocks 15 then drive the limiting plate 16 to move. At the same time, the limiting plate 16 disengages from the limiting groove 41, and the limitation of the limiting plate 16 on the connecting frame 4 is released. Then, the user repeats the above steps, and the limitation of multiple connecting frames 4 is released. Finally, the user pulls the front cover 2 and the rear cover 3 to the front and rear sides respectively, and the connecting frame 4 disengages from the connecting groove 120. The sealing sleeve 5 disengages from the housing 1, and the front cover 2 and the rear cover 3 can be disassembled.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
