[0002] In mechanical transmission systems, the motor adjusting bracket, as a key component connecting the motor and the transmission mechanism, directly affects the performance and reliability of the entire transmission system through its assembly accuracy and stability. Traditional motor adjusting bracket assembly processes often suffer from problems such as inaccurate positioning and low assembly efficiency.

[0003] Specifically, traditional assembly methods typically rely on manual positioning. Due to human error, it's difficult to ensure that each drive shaft mounting bracket and gear is precisely in place, leading to accumulated assembly errors and affecting overall assembly accuracy. Furthermore, during assembly, the gear position is often changed by turning screws. This requires continuous screw turning for adjustment, making the gear drive shaft installation process cumbersome and time-consuming, thus reducing production efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an assembly and positioning fixture for a motor adjustment bracket. The main body of the fixture provides a precise positioning reference for the drive shaft fixing seat and the drive gear, ensuring accuracy and consistency in the assembly process. The fixing plate enables the rapid and stable installation of the gear drive shaft, greatly improving assembly efficiency.

The upper end face of the assembly and positioning fixture body is provided with multiple fixed seat mounting slots. A drive shaft fixed seat is detachably connected in the fixed seat mounting slot.

[0007] The drive shaft mounting base is detachably connected to a gear drive shaft via an installation assembly, and a drive gear is fixedly mounted on one end of the gear drive shaft.

[0008] The upper surface of the assembly positioning fixture body is provided with multiple transmission gear mounting slots that are adapted to the transmission gears, and the transmission gears are located in the transmission gear mounting slots.

[0009] Preferably, the mounting assembly includes a snap-fit ​​member disposed on the upper end face of the drive shaft mounting base, wherein a fixing plate for pressing the gear drive shaft is snapped onto the snap-fit ​​member, and two fixing protrusions for limiting the fixing plate are fixedly installed on both sides of the snap-fit ​​member.

[0010] Preferably, the pressing plate fixing protrusion has a triangular structure, and the inclined surface is inclined from top to bottom in the direction away from the snap-fit ​​component.

[0011] Preferably, the snap-fit ​​component, the drive shaft fixing seat, and the pressure plate fixing protrusion are integrally formed.

[0012] Preferably, the end of the gear drive shaft that contacts the snap-fit ​​component has an oval shape, and the plane of the oval shape is horizontal.

[0013] Preferably, the fixing plate is made of an elastic material, the middle part of the fixing plate has an arc structure, and the left and right ends of the arc structure are raised.

[0024] Reference Figures 1-3 The motor adjustment bracket assembly and positioning fixture includes an assembly and positioning fixture body 1. The upper end face of the assembly and positioning fixture body 1 is provided with multiple fixed seat mounting slots 2. A drive shaft fixed seat 3 is detachably connected in the fixed seat mounting slot 2.

[0025] The drive shaft mounting base 3 is detachably connected to the gear drive shaft 5 via the mounting assembly. The end of the gear drive shaft 5 that contacts the snap-fit ​​7 has an oval structure with the plane of the oval structure in a horizontal state. This design facilitates precise docking with the snap-fit ​​7 and ensures the stability of the drive shaft in the horizontal direction. A drive gear 6 is fixedly installed at one end of the gear drive shaft 5. The front and rear sections of the gear drive shaft 5 are rotatably connected. The rear section is used for stable support and fixation, and the front section is used for gear connection.

[0026] The mounting assembly includes a snap-fit ​​component 7 on the upper surface of the drive shaft mounting base 3. A fixing plate 9 for pressing the gear drive shaft 5 is snapped onto the snap-fit ​​component 7. Two fixing protrusions 8 for limiting the fixing plate 9 are fixedly installed on both sides of the snap-fit ​​component 7. The fixing protrusions 8 are triangular in structure, and the inclined surface is inclined from top to bottom in the direction away from the snap-fit ​​component 7.
