Description

Technical Field

[0001] This invention relates to the field of direct drive motor assembly technology, and more specifically to a direct drive motor tooling. Background Technology

[0002] A direct-drive motor is a type of motor that directly drives a load. Typically, the stator and rotor of the motor are directly connected to the load, eliminating the intermediate transmission devices such as gears, belts, and chains used in traditional motors to transmit power. It operates based on the principle of electromagnetic induction, where the magnetic field generated by the stator windings interacts with the rotor, causing the rotor to directly drive the load. Direct-drive motors usually have a larger diameter and a shorter axial length. This structural design helps increase the motor's torque output, enabling it to directly drive large loads. Because direct-drive motors eliminate intermediate transmission devices, they reduce energy loss during transmission, thus achieving higher energy conversion efficiency and energy savings.

[0003] Because direct-drive motors directly drive the position and movement of the rotor, their precision is far higher than that of ordinary motors. The air gap between the stator and rotor of a direct-drive motor is typically small, requiring extremely high assembly precision. Furthermore, due to the relatively complex structure of direct-drive motors, the lack of specialized assembly tooling during assembly leads to variations that can result in uneven air gaps between the stator and rotor, uneven magnetic field distribution, vibration, and noise. This reduces the motor's performance and lifespan. Therefore, providing a tooling and assembly process for direct-drive motors that improves precision and extends service life is an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art and provide a tooling for a direct drive motor, which enables the assembly of the direct drive motor to achieve a significant improvement in assembly accuracy through dedicated assembly work and assembly process, thereby further improving the working performance of the direct drive motor.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A direct-drive motor fixture includes a pressing fixture, which comprises a pressing support frame and a pressing platform. Both the pressing support frame and the pressing platform have pressing support columns at their bottoms for supporting the pressing fixture. The pressing platform is mounted on the pressing support frame. The pressing support frame has several pressing guide columns, each with an upper plate at its top. A pressing platform is movably mounted on each pressing guide column, and a base support frame is fixedly mounted at its bottom. The pressing platform's movement within the pressing guide columns can cause the base support frame to move accordingly.

[0007] Preferably, the lower pressing platform is provided with a plurality of guide holes corresponding to the lower pressing guide column, a pressure handle is provided at the top of the lower pressing platform and extends out of the upper platform plate, a circular hole is opened in the center of the upper platform plate for the pressure handle to extend out, and a support frame locking part is also provided at the bottom of the lower pressing platform for locking and installing the machine base support frame; the guide hole design on the lower pressing platform allows the lower pressing platform to move up and down along the lower pressing guide column, and the pressure handle provided on the lower pressing platform can be driven to press down together under the pressure of an external press, and at the same time drive the machine base support frame below the lower pressing platform to perform a downward pressing movement.

[0008] Preferably, the machine base support frame includes a support frame mounting part and a downward pressure application part, which are perpendicularly and fixedly connected to each other. A downward pressure support rib is also fixedly provided between them to increase the strength of the machine base support frame. The support frame mounting part and the support frame locking part are locked together. The machine base support frame is mounted on the support frame locking part of the lower press platform through the support frame mounting part. The support frame mounting part and the downward pressure application part are designed perpendicularly, and a downward pressure support rib is provided between them to increase the strength, so that the machine base support frame can provide greater downward pressure during the pressing process of the external press.

[0009] Preferably, the surface of the pressing force application part is symmetrically arranged with a plurality of locking threaded holes at the center and both sides. The tooling installed on the pressing force application part can be adjusted in height through the locking threaded holes. Limiting blocks are also symmetrically arranged at the edges on both sides of the surface of the pressing force application part. The width between the limiting blocks is consistent with the width of the motor housing base. The pressing force application part is provided with locking threaded holes at the center and both sides. The triangular press-fit tooling or the motor housing can be locked and fixed to the pressing force application part with screws. The locking threaded holes are designed in a symmetrical array, so the installation height of the triangular press-fit tooling or the motor housing can be adjusted by locking position. The pressing force application part is also provided with limiting blocks. The width between the limiting blocks is consistent with the width of the motor housing base. When the housing is locked and installed on the pressing force application part, the limiting blocks can keep the motor housing in the center position of the pressing force application part.

[0010] Preferably, a triangular press-fit fixture can also be installed on the pressing force application part. The triangular press-fit fixture includes a triangular reinforcing rib, and the two straight sides of the triangular reinforcing rib are provided with triangular rib thickening parts. The triangular rib thickening part on one of the straight sides is also provided with a triangular rib mounting hole corresponding to the locking thread hole at the center position of the pressing force application part.

The outer diameter of the rotor sleeve support fixture is consistent with the outer diameter of the rotor sleeve of the direct drive motor. A stop is provided on one end face of the rotor sleeve support fixture, which cooperates with the stop on the end face of the rotor sleeve of the direct drive motor. The bearing pressing fixture is used to press the front and rear bearings into the bearing chambers on the front and rear end covers of the motor. Therefore, the outer diameter of the bearing pressing fixture is consistent with the inner ring size of the motor bearing. The stop is provided on the end face of the rotor sleeve support fixture, which cooperates with the stop of the motor rotor sleeve. When assembling the rotor sleeve and the spindle using the rotor sleeve support fixture, the concentricity between the rotor sleeve support fixture and the rotor sleeve can be ensured, thus improving the assembly accuracy.

[0012] Preferably, the pressing fixture further includes a housing center positioning fixture and a rotor sleeve center positioning fixture. The outer diameter of the housing center positioning fixture is consistent with the housing size of the direct drive motor. One end of the housing center positioning fixture has a protruding stop that mates with the end stop of the housing, and the other end has a concave stop that mates with the stop on the rotor sleeve center positioning fixture. The rotor sleeve center positioning fixture includes a positioning base and a spindle fixing block. The spindle fixing block is composed of two symmetrical fixing blocks connected by a fixing connection, and a spindle fixing hole is provided between the spindle fixing blocks. The stop at the end of the housing center positioning fixture that mates with the housing mates with the stop on the housing, and the stop at the end of the housing center positioning fixture that mates with the stop on the rotor sleeve center positioning fixture, can ensure the concentricity of the assembly of the housing, the housing center positioning fixture, and the rotor sleeve center positioning fixture.

[0013] Preferably, the rotor sleeve center positioning fixture is also provided with a spindle positioning support fixture. The spindle positioning support fixture has a U-shaped hole on its side wall for observing the installation of the internal spindle.
