Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor assembly technology, specifically to a permanent magnet motor assembly device. Background Technology
[0002] In the assembly process of permanent magnet motors, especially large permanent magnet motors, the large size and heavy weight place high demands on the stability and flexibility of the assembly equipment. Existing assembly equipment for large permanent magnet motors typically possesses basic support, positioning, and lifting functions to facilitate assembly operations at different heights. For example, some existing assembly equipment uses a turntable to allow for angle adjustment during assembly, facilitating the installation of components from different parts of the motor. However, in practical applications, these assembly equipment face several unresolved issues regarding angle adjustment, impacting assembly efficiency and operational safety.
[0003] In the prior art, such as the large permanent magnet motor assembly device disclosed in the Chinese authorized patent (publication number: CN202322793973.2), the positioning and lifting of the motor are achieved through the cooperation of the turntable and the support components. However, large motors are heavy, and the rotation adjustment of the turntable lacks an effective self-locking mechanism. During the assembly process, the motor may rotate unexpectedly due to external forces or vibrations of the device itself, thereby affecting the assembly accuracy. Utility Model Content
[0004] The purpose of this invention is to provide a permanent magnet motor assembly device that solves the problem of accidental motor rotation by using a locking mechanism to self-lock the turntable.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model is a permanent magnet motor assembly device, including a support platform and a locking mechanism. A rotating groove is provided on the support platform, and a rotating platform is fitted inside the groove. A rotating shaft is vertically fitted at the bottom end of the groove. A circular hole is provided on the rotating platform to fit the rotating shaft. The locking mechanism has a worm and a worm wheel, with the worm meshing with the worm wheel. A through hole is provided in the support platform, which is connected to the rotating groove. The worm passes through the through hole and extends outside the through hole. The worm wheel is sleeved at the bottom end of the rotating shaft.
[0007] Furthermore, mounting holes are provided at the four corners of the support platform, and each mounting hole is fitted with a column.
[0008] Furthermore, through holes are provided at the four corners of the support platform, each through hole is connected to the corresponding mounting hole, and a locking rod is slidably fitted in each through hole. A positioning hole for the corresponding locking rod is provided at the bottom of each column.
[0009] Furthermore, the ends of the levers are chamfered, and gantry rods are installed on the tops of two adjacent levers. Springs connect the two ends of the gantry rods to the support platform.
[0010] Furthermore, C-shaped rods are installed on both sides of the support platform, and two adjacent clamps contact the C-shaped rods.
[0011] Furthermore, mounting platforms are installed at the top of the four columns, and hydraulic cylinders are installed on the mounting platforms.
[0012] This utility model has the following beneficial effects:
[0013] This utility model uses a locking mechanism to self-lock the turntable. Since the worm gear mechanism has a reverse self-locking function, when the worm stops rotating, the turntable cannot rotate unexpectedly due to the motor's own weight or assembly vibration. Compared with friction braking or manual locking structures, mechanical interlocking is more reliable and effectively ensures the stability of the assembly process. In addition, the worm passes through the support table through a hole and is exposed, so the operator can apply force directly from the side of the device without taking up extra space.
[0014] This utility model features a quick-release column. By pulling the gantry rod, two adjacent levers can be pulled out simultaneously. A spring provides automatic rebound force, enabling tool-free disassembly and assembly of the column. This greatly simplifies the maintenance process and facilitates cleaning, inspection, or replacement of the support platform or column. The disassembled column and support platform can be stored separately, significantly reducing the overall volume and minimizing the space occupied by large equipment in narrow workshops or long-distance transportation, thus adapting to the needs of multiple usage scenarios.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a permanent magnet motor assembly device, including a support platform 1 and a locking mechanism. The support platform 1 has a rotating groove 101, within which a turntable 3 is fitted. A rotating shaft 2 is vertically fitted at the bottom end of the rotating groove 101. The turntable 3 has a circular hole for fitting the rotating shaft 2. The locking mechanism has a worm gear 5 and a worm wheel 4. When the motor load is ≤500kg, the worm gear 4 and worm 5 do not rotate spontaneously at a vibration frequency ≤50Hz. The worm gear 4 and worm 5 are standard parts, selected according to load requirements. The worm gear 5 meshes with the worm wheel 4. A through hole 102 is provided inside the rotating shaft 2, which is connected to the rotating groove 101. The worm 5 passes through the through hole 102 and extends to the outside of the through hole 102. The worm wheel 4 is sleeved at the bottom end of the rotating shaft 2. The rotating table 3 is rotated and supported by the rotating shaft 2. The operator can drive the worm wheel 4 by rotating the worm 5, which in turn drives the rotating shaft 2 to rotate, so that the rotating table 3 rotates. Since the worm wheel and worm gear mechanism has a self-locking characteristic, when the worm 5 stops rotating, the worm wheel 4 cannot drive the worm 5 in the opposite direction, thereby preventing the rotating table 3 from being accidentally deflected due to the weight of the motor or vibration, and ensuring the stability during the assembly process.
[0023] Mounting holes 103 are provided at each of the four corners of the support platform 1. Each mounting hole 103 is fitted with a column 6. A mounting platform 601 is installed on the top of each of the four columns 6. A hydraulic cylinder 602 is installed on the mounting platform 601. The output end of the hydraulic cylinder 602 is connected to a support plate. The support plate is equipped with a positioning component (not shown in the figure) for fixing the permanent magnet motor. The support plate and positioning component are existing technologies and will not be described in detail here. Through holes 104 are provided at each of the four corners of the support platform 1. Each through hole 104 is connected to the corresponding mounting hole 103. A locking rod 7 is slidably fitted in each through hole 104. The locking rod 7 is made of steel and can withstand the strong static load of a single column. A positioning hole 603 is provided at the bottom of each column 6 to fit the corresponding locking rod 7. The end of the locking rod 7 is chamfered 701. A gantry rod 8 is installed on the top of two adjacent locking rods 7. The two ends of the gantry rod 8 are connected to the... A spring 9 connects the support platform 1. C-shaped rods 10 are installed on both sides of the support platform 1. Two adjacent locking rods 7 contact the C-shaped rods 10. The mounting holes 103 at the four corners of the support platform 1 allow the column 6 to be inserted into the mounting holes 103 and locked by the locking rods 7. The chamfer 701 at the end of the locking rod 7 facilitates insertion into the positioning hole 603 at the bottom of the column 6. When the column 6 needs to be disassembled, simply pull the gantry rod 8 on one side to move the two adjacent locking rods 7 out of the positioning hole 603. The spring 9 is stretched, and the column 6 is released from its limit and can be removed freely. During installation, the gantry rod 8 is released, and the spring 9 rebounds to push the locking rod 7 back into the positioning hole 603, completing the locking. To prevent the locking rod 7 from moving too far, C-shaped rods 10 are provided on both sides of the support platform 1. When the locking rod 7 is pulled out to its limit position, it will contact the inner surface of the C-shaped rod 10 to avoid excessive movement that could damage the structure.
