Description

Technical Field

[0001] This utility model relates to the field of end-cover-less motor trial operation technology, specifically, to a tooling that facilitates the trial operation of end-cover-less motors. Background Technology

[0002] Plastic-encapsulated motors use plastic encapsulation technology to encapsulate the stator core, windings, and other components of the motor entirely with engineering plastics. This eliminates the need for traditional motor stator insulation processes and the metal casing of ordinary motors, and is widely used in household appliances such as integrated stoves and range hoods.

[0003] However, existing fixing methods mostly use dedicated fixtures, which can only be adapted to motors without end caps of a single size. When dealing with motors of different models and sizes, it is necessary to frequently change the fixtures, which is cumbersome and inefficient, increases production and debugging costs, and cannot meet diverse trial operation needs. Therefore, those skilled in the art provide a tooling that facilitates the trial operation of motors without end caps to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for easy trial operation of end-cover-less motors, thereby solving the problems in the prior art.

[0005] This utility model provides the following technical solution: a tooling for easy trial operation of a motor without an end cap, including a base plate for supporting the upper part, a fixing mechanism for fixing motors without end caps of different sizes is provided at the upper center of the base plate, and a positioning component for positioning the motor without end caps is provided on the upper side of the base plate.

[0006] As a preferred embodiment of the above technical solution, the fixing mechanism includes a first fixing column, which is fixedly connected to the upper end of the base plate near both sides. The inner cavity of the first fixing column is hinged with a first hinge, and a cylinder is fixedly connected to the end of the first hinge away from the first fixing column.

[0007] As a preferred embodiment of the above technical solution, a telescopic rod is slidably connected to the inner cavity of the cylinder at the end away from the first hinge, and a second hinge is fixedly connected to the end of the telescopic rod away from the cylinder.

[0008] As a preferred embodiment of the above technical solution, the upper end of the base plate is fixedly connected to the two sides of the base plate, the outer side of the movable shaft is slidably connected to the movable column, and the movable column is hinged to the second hinge. The upper end of the movable column is fixedly connected to the fixed plate, and the end of the fixed plate away from the movable column is fixedly connected to the soft pad.

[0009] As a preferred embodiment of the above technical solution, a second fixed column is fixedly connected to the upper center of the base plate, a first connecting plate is rotatably connected to the upper end of the second fixed column, the two ends of the first connecting plate are hinged to the second connecting plate, and a rotating shaft is rotatably connected to the end of the second connecting plate away from the first connecting plate, and the rotating shaft is fixedly connected to the upper end of the movable column.

[0010] As a preferred embodiment of the above technical solution, the positioning component includes a third fixing post, which is fixedly connected to the upper end of the base plate near both sides. An annular fixture is fixedly connected to the top of the third fixing post, and a bearing is rotatably connected to the inner cavity of the annular fixture. The bearing is rotatably positioned on the outer side of the soft pads symmetrically arranged on both sides.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a fixing mechanism. The first fixing columns on both sides of the base plate serve as a stable mounting foundation. A first hinge allows for flexible adjustment of the cylinder angle, accommodating the fixing angle requirements of end-cap-less motors of different sizes. The cylinder drives the telescopic rod to extend and retract, which in turn drives the movable column to slide along the moving axis via the second hinge. Combined with the upper fixing plate and soft pad on the movable column, the elasticity of the soft pad prevents damage to the motor housing from hard contact, while the sliding of the movable column adjusts the clamping position to meet the fixing requirements of motors of different sizes. Simultaneously, the linkage structure formed by the second fixing column in the center of the base plate, the first connecting plate, and the second connecting plate ensures synchronous sliding of the movable columns on both sides, effectively preventing motor misalignment due to asynchronous sliding on one side. This significantly improves the stability, adaptability, and reliability of fixing end-cap-less motors of different sizes.

[0012] Based on the above-mentioned beneficial effects, this utility model is equipped with a positioning component. The third fixed columns on both sides of the upper end of the base plate serve as a stable support foundation, and the annular fixture at the top provides a reliable mounting carrier for the bearing. The bearing, which is rotatably connected to the inner cavity of the annular fixture, cooperates with the outer sides of the symmetrical soft pads on both sides. After the fixing mechanism completes the motor fixing, during the motor test run, the bearing can not only provide stable radial support for the rotating parts of the motor, effectively limiting the sway amplitude during the motor rotation process and avoiding abnormal motor operation or damage due to positioning deviation, but also reduce the frictional resistance of the motor during operation through its own flexible rotation, ensuring that the motor is always in a precise operating position.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: a tooling for easy trial operation of a motor without an end cap, including a base plate 1 for supporting the upper part, a fixing mechanism 2 for fixing motors without end caps of different sizes is provided at the upper center of the base plate 1, and a positioning component 3 for positioning the motor without end caps is provided on the upper side of the base plate 1.

[0017] The base plate 1 serves as a basic support structure, providing a stable installation platform for the upper fixing mechanism 2 and positioning assembly 3. After the fixing mechanism 2 is activated, the operation of the cylinder 23 on the first fixing column 21 drives the telescopic rod 24 to extend and retract. With the help of the second hinge 25, the movable column 27 slides along the moving shaft 26 on both sides of the base plate 1. At the same time, under the linkage of the second fixing column 210, the first connecting plate 211 and the second connecting plate 212, the movable columns 27 on both sides move synchronously, so that the soft pad 29 on the upper fixing plate 28 of the movable column 27 fits into the end cap of the motor housing of different sizes for stable fixation. The positioning assembly 3 supports and guides the rotating parts of the motor through the bearing 33 in the annular tooling 32 at the top of the third fixing column 31 on both sides of the base plate 1, reducing the shaking during the test run of the motor.

[0018] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, the fixing mechanism 2 includes a first fixing post 21, which is fixedly connected to the upper end of the base plate 1 near both sides. The inner cavity of the first fixing post 21 is hinged with a first hinge 22, and the end of the first hinge 22 away from the first fixing post 21 is fixedly connected to a cylinder 23.

[0019] The first fixed posts 21 on both sides of the upper end of the base plate 1 serve as basic installation support components. The inner cavity of the first fixed post 21 is connected to the first hinge 22 by a hinge. The hinge characteristic allows the first hinge 22 to be flexibly adjusted in angle. The end of the first hinge 22 away from the first fixed post 21 is fixedly connected to the cylinder 23. This structural design allows the cylinder 23 to use the angle adjustment function of the first hinge 22 to adapt to the motor fixing requirements when fixing motors of different sizes without end caps in the subsequent work. This provides a stable and adjustable installation and power output foundation for the cylinder 23 to subsequently drive related components to fix the motor.

[0020] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, a telescopic rod 24 is slidably connected to the inner cavity of the cylinder 23 at the end away from the first hinge 22, and a second hinge 25 is fixedly connected to the end of the telescopic rod 24 away from the cylinder 23.

[0021] When cylinder 23 is started, its inner cavity at the end away from the first hinge 22 will drive the telescopic rod 24 that is slidably connected to it to perform telescopic movement according to the actual size requirements of the end capless motor to be fixed; since the end of telescopic rod 24 away from cylinder 23 is fixedly connected to the second hinge 25, the telescopic movement of telescopic rod 24 will synchronously drive the second hinge 25 to move.

[0022] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, a movable shaft 26 is fixedly connected to the upper end of the base plate 1 on both sides. A movable column 27 is slidably connected to the outer side of the movable shaft 26. The movable column 27 is hinged to the second hinge 25. A fixed plate 28 is fixedly connected to the upper end of the movable column 27. A soft pad 29 is fixedly connected to the end of the fixed plate 28 away from the movable column 27.

[0023] The movable shafts 26 fixed on both sides of the upper end of the base plate 1 provide a stable sliding track for the movable column 27, which can slide flexibly along the outer side of the movable shafts 26. Since the movable column 27 is hinged to the second hinge 25, when the second hinge 25 is displaced under the drive of the telescopic rod 24, it will synchronously drive the movable column 27 to adjust its position along the movable shaft 26. At the same time, the fixing plate 28 fixed at the upper end of the movable column 27 moves synchronously with the movable column 27, and the soft pad 29 at the end of the fixing plate 28 away from the movable column 27 also approaches the end capless motor. Finally, through the contact between the soft pad 29 and the motor housing, the motor is clamped and fixed while avoiding damage to the motor housing. The sliding of the movable column 27 along the movable shaft 26 can adapt to motors of different sizes.

[0024] As one implementation method in this embodiment, please refer to Figures 3-4As shown, a second fixed column 210 is fixedly connected to the center of the upper end of the base plate 1. A first connecting plate 211 is rotatably connected to the upper end of the second fixed column 210. A second connecting plate 212 is hinged to both ends of the first connecting plate 211. A rotating shaft 213 is rotatably connected to the end of the second connecting plate 212 away from the first connecting plate 211, and the rotating shaft 213 is fixedly connected to the upper end of the movable column 27.

[0025] The second fixed column 210 at the center of the upper end of the base plate 1 serves as the core support point. Its upper end is rotatably connected to the first connecting plate 211, providing a stable rotational foundation for the first connecting plate 211. The two ends of the first connecting plate 211 are connected to the second connecting plate 212 by hinges, allowing the second connecting plate 212 to rotate flexibly around the end of the first connecting plate 211. The end of the second connecting plate 212 away from the first connecting plate 211 is fixedly connected to the upper end of the movable column 27 through the rotating shaft 213. When the movable column 27 slides along the moving shaft 26 under the drive of the telescopic rod 24 and the second hinge 25, it will drive the second connecting plate 212 to move synchronously through the rotating shaft 213. The second connecting plate 212 then pushes the first connecting plate 211 to rotate around the second fixed column 210. Through this series of rotation and hinge linkages, it is ensured that the movable columns 27 on both sides always maintain synchronous sliding.

[0026] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the positioning component 3 includes a third fixing post 31, which is fixedly connected to the upper end of the base plate 1 near both sides. The top end of the third fixing post 31 is fixedly connected to an annular fixture 32, and the inner cavity of the annular fixture 32 is rotatably connected to a bearing 33. The bearing 33 is rotatably disposed on the outer side of the soft pads 29 symmetrically arranged on both sides.

[0027] The third fixed column 31, which is fixedly connected to both sides of the upper end of the base plate 1, serves as the basic support. The annular tooling 32 fixed at the top provides the installation carrier for the positioning core component. The bearing 33, which is rotatably connected to the inner cavity of the annular tooling 32, cooperates with the outer side of the soft pads 29 symmetrically arranged on both sides. After the fixing mechanism 2 completes the fixing of the end coverless motor through the soft pads 29, the bearing 33 can rotate flexibly around its own axis during the motor trial operation. This not only forms a stable radial support for the rotating parts of the motor and limits the sway amplitude when the motor rotates, but also reduces the frictional resistance of the motor during operation through its own rotation, ensuring that the motor always maintains a precise operating position during the trial operation.

[0028] Working principle: During overall operation, the fixing mechanism 2 first securely fixes the end capless motors of different sizes: the first fixing posts 21 on both sides of the base plate 1 provide the mounting base for the cylinder 23. After the cylinder 23 adjusts its angle with the help of the first hinge 22, it starts to drive the telescopic rod 24 to extend and retract. Then, through the second hinge 25, it drives the movable post 27, which is slidably sleeved on the moving shaft 26, to slide synchronously. The soft pad 29 on the upper fixing plate 28 of the movable post 27 then fits against the motor housing, avoiding damage while achieving stable clamping. At the same time, the positioning component 3 works in conjunction. The bearing 33 in the annular tooling 32 at the top of the third fixing posts 31 on both sides of the base plate 1 is sleeved on the outside of the soft pad 29. When the motor rotates during trial operation, it provides radial support for the rotating parts of the motor to reduce shaking, and also reduces frictional resistance through its own rotation. Finally, it achieves the synergistic effect of stable fixation and precise positioning during the trial operation of the end capless motor.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
