Description

Technical Field

[0001] This utility model relates to the field of motor auxiliary tooling technology, specifically to a tooling for mounting magnets and pins on a motor housing. Background Technology

[0002] In the field of motor manufacturing, magnets are an important component of the motor rotor or stator, and their installation quality directly affects the motor's performance, efficiency, and service life. Magnets are typically installed on the inner surface of the motor housing (casing) and interact with internal components such as coils to generate a magnetic field, driving the motor's operation. However, traditional magnet installation methods have many problems, especially during motor operation. Due to factors such as motor heat and vibration, magnets are prone to detachment or displacement, severely impacting the motor's stability and reliability.

[0003] Currently, most motor internal magnets are installed using an adhesive patch method. Specifically, a layer of adhesive is first applied to the inner surface of the motor housing, then the magnet is attached to the adhesive. After the adhesive cures, the magnet is fixed to the motor housing. However, this installation method has significant limitations. Firstly, the adhesive's curing process can be affected by factors such as ambient temperature and humidity, leading to uneven curing or insufficient strength, thus affecting the magnet's fixation. Secondly, during motor operation, factors such as motor heat and vibration can cause the adhesive to gradually age and fail, leading to the magnet detaching or shifting.

[0004] To effectively prevent magnetic tiles from detaching or shifting, a magnetic tile fixing structure has been proposed in the prior art. This structure has two magnetic tile pins on the inner surface of the motor housing. One side of each pin abuts against one end of a magnetic tile, and the other side abuts against one end of the other magnetic tile, fitting snugly against the inner surface of the motor housing. This structure mechanically fixes the magnetic tiles using the pins, improving the fixing effect. However, existing installation methods mainly rely on manual operation, and the following problems still exist.

[0005] First, existing manual installation methods struggle to ensure precise alignment between the magnetic tile and its pin. During installation, the magnetic tile and pin are prone to slippage, making accurate positioning difficult and affecting motor performance. Furthermore, manual operation is susceptible to variations in operator skill level and fatigue, further reducing installation precision.

[0006] Secondly, manual installation requires operators to install the magnets and their pins onto the motor housing one by one, a tedious and time-consuming process. Especially in mass production, manual installation is inefficient and cannot meet the demands of large-scale production.

[0007] Because manual installation makes it difficult to ensure a precise fit between the magnetic tile and its pin, there is still a risk that the magnetic tile may fall off or shift during motor operation. Furthermore, the magnetic tile pin may be deformed or damaged by external forces during installation, further affecting the secure hold of the magnetic tile.

[0008] Existing manual installation methods lack standardization and automation, making it difficult to guarantee installation quality. Differences in operating habits and skill levels among operators can lead to inconsistent installation quality even within the same batch of products. Furthermore, manual installation methods make real-time monitoring and traceability of the production process difficult, hindering product quality control and improvement.

[0009] Therefore, it is particularly important to develop a tooling specifically for mounting magnets and pins on motor housings to address these problems in the existing technology. Utility Model Content

[0010] The purpose of this utility model is to provide a tooling for mounting magnets and pins on a motor housing, thereby solving the technical problem of inaccurate magnet installation.

[0011] The objective of this utility model can be achieved through the following technical solutions:

[0012] A fixture for mounting magnets and pins on a motor housing includes a fixture base and a fixture pressure head. A threaded sleeve is fixedly mounted on the upper end of the fixture base, and a positioning sleeve is fixedly mounted on the upper end of the threaded sleeve. The outer diameter of the positioning sleeve matches the inner diameter of the motor housing. The outer wall of the positioning sleeve is symmetrically provided with slider grooves, and a magnet positioning post for positioning and mounting the motor magnets is adjustablely mounted in the slider groove. The fixture pressure head cooperates with the motor housing to install the magnet pins between two sets of motor magnets.

[0013] Preferably, both sides of the tooling base are provided with base mounting grooves for fixing and installing the tooling base.

[0014] Preferably, the tooling base has a mounting hole at its center for mounting a threaded sleeve, and a bolt threadedly connected to the threaded sleeve is installed at the mounting hole.

[0015] Preferably, the outer periphery of the threaded sleeve is movably connected to a positioning bracket washer for supporting the motor housing.

[0016] Preferably, the positioning frame washer is threaded onto the outer periphery of the threaded sleeve, and the positioning frame washer is provided with a washer locking hole for installing bolts.

[0017] Preferably, the bottom of the slider groove is provided with a locking screw hole for installing the magnetic tile positioning post, and the magnetic tile positioning post is provided with an adjustment waist hole that cooperates with the locking screw hole.

[0018] Preferably, the tooling pressure head includes a pressure handle, and a positioning pressure plate for pressing the magnetic tile pin is fixedly provided at the lower end of the pressure handle. The outer diameter of the tooling pressure head is equal to the outer diameter of the motor housing, and the length of the positioning pressure plate is equal to the inner diameter of the motor housing.

[0019] Preferably, the upper end of the pressure handle is fixedly mounted with a pressure cap for pressing and lifting the tooling pressure head by bolts.

[0020] Preferably, a pin positioning plate is fixedly provided at the end of the positioning plate away from the pressure handle, and the pin positioning plate cooperates with the groove on the magnetic tile pin.

[0022] The beneficial effects of this utility model are:

[0023] (1) The positioning sleeve is used to fix the motor housing in place, ensuring the stability of the motor housing on the tooling. Through the precise design of the positioning sleeve, it can be ensured that the motor housing will not shift or shake during the installation process, thereby improving the installation accuracy.

[0024] (2) The positioning bracket washer is used to adjust the installation height of the motor housing and limit the axial installation of the magnet. By adjusting the height of the positioning bracket washer, the installation position of the magnet inside the motor housing can be precisely controlled, ensuring that the gap between the magnet and the coils and other components inside the motor is uniform, thereby improving the performance of the motor.

[0025] (3) Two sets of symmetrically distributed magnetic tile positioning posts are used to limit the radial installation of the two sets of magnetic tiles. Through the precise design of the magnetic tile positioning posts, it can be ensured that the magnetic tiles will not shift or tilt during installation, thereby improving the installation accuracy and stability of the magnetic tiles.

[0026] (4) The tooling head is used to press the magnetic tile pins stably into the space between the two sets of magnetic tiles, thereby achieving precise installation of the magnetic tile pins. Through the precise control of the tooling head, it can be ensured that the magnetic tile pins will not be deformed or damaged during the installation process, while ensuring a tight fit between the magnetic tile pins and the magnetic tiles, thus improving the fixing effect of the magnetic tiles.
