Description
Technical Field
[0001] The utility model relates to the technical field of fan installation, in particular to a tooling fixture for a fan motor. Background Art
[0002] The brushless fan motor is an advanced type of motor, which is widely used in various fan products, including household fans, industrial fans, and computer cooling systems. The design of this motor is very different from that of traditional brushed motors. It uses electronic commutation instead of physical carbon brushes and commutators, so it has higher efficiency, lower noise, and longer service life.
[0003] In the existing technology, when assembling the motor using conventional methods, since multiple magnets are installed in the stator iron shell and the magnet suction force is too large, when closing the upper cover and the lower cover of the motor, the iron core is directly attracted by the magnetic force, which easily causes hand injuries or damage to the upper and lower cover parts during the installation process. At the same time, the concentricity deviation of the assembled motor is likely to cause abnormal problems of the motor. Therefore, in order to solve the above technical problems, the utility model proposes a tooling fixture for a fan motor. Summary of the Utility Model
[0004] The purpose of the utility model is achieved in the following way: A tooling fixture for a fan motor includes a mounting base, an upper clamping assembly, and a lower positioning assembly. The lower positioning assembly is fixedly installed with the mounting base. The upper clamping assembly is arranged above the lower positioning assembly. The lower positioning assembly includes a placement seat and a limiting ring. The placement seat is arranged on the top surface of the mounting base. The limiting ring is detachably arranged on the top surface of the placement seat. A positioning ring is arranged on the top surface of the placement seat. A clamping protrusion matching the outer diameter of the positioning ring is arranged at a position on the bottom surface of the limiting ring close to the positioning ring. Limiting protrusions are distributed in the middle of the positioning ring. An installation groove matching the inner diameter of the positioning ring is arranged at a position on the top surface of the placement seat close to the limiting protrusions. The upper clamping assembly includes a control cylinder, a converging seat, and a clamping disc. The converging seat is arranged above the placement seat and is concentric with the placement seat.

The control cylinder is arranged on the top surface of the converging seat, and the push rod of the control cylinder passes through the converging seat and is connected to the clamping disc. The clamping disc is made of a silicone material combination.
[0005] In the above description, as a further solution, a lifting assembly is arranged above the converging seat. The lifting assembly includes support columns, a limiting plate, and a lifting cylinder. The support columns are fixed at the four corners of the top surface of the mounting base. The ends of the support columns away from the mounting base extend in a direction away from the mounting base. The limiting plate is fixedly installed on the top surface of the support columns. The lifting cylinder is fixed in the middle of the top surface of the limiting plate, and the push rod of the lifting cylinder passes through the limiting plate and is connected to the converging seat. The lifting cylinder is used to drive the converging seat and the clamping disc to lift to achieve the installation function.
[0006] In the above description, as a further solution, a connection disk and connection columns are provided between the lifting air cylinder and the converging seat. The connection disk is fixedly connected to the push rod of the lifting air cylinder. The connection columns are evenly distributed along the edge of the bottom surface of the connection disk, and the control air cylinder is arranged between the connection columns. The connection disk and the connection columns are used to provide the connection effect between the lifting air cylinder and the converging seat.

[0008] In the above description, as a further solution, a placement groove is formed in the middle of the bottom surface of the installation groove, and the placement groove extends towards the direction of the installation seat. The placement groove is used to adapt to the placement of the product.
[0009] In the above description, as a further solution, a connection hole is formed in the top surface of the limiting ring near the limiting protrusion, and the connection hole penetrates and extends towards the direction of the placement seat. A threaded hole matching the connection hole is provided at the position of the top surface of the placement seat near the connection hole. The connection hole and the threaded hole can be used to provide the functions of replacing and installing the limiting ring.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the setting of the upper clamping assembly and the lower positioning assembly, when assembling the upper cover body and the lower cover body of the motor, it is only necessary to fit the upper cover body of the motor with the clamping disk.
