Description
Technical Field
The utility model relates to a motor or electromechanical technical field, concretely relates to motor drive base plate riveted structure.
Background
At present, a drive substrate and a bearing support of an existing direct current brushless motor are generally fixed by screws in a circumferential and axial constraint mode, the structure can meet the requirements under the conditions that the requirement on rotation precision is not high or the vibration of a mounting and connecting structure used by the motor is small, but under the conditions that the requirement on rotation precision is high and the vibration of the structure used by the motor is frequent, the drive substrate and the bearing support are easily combined insecurely to cause the loosening of an iron core, so that the conditions of poor rotation precision and rotation failure of the motor are caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome above problem, the utility model provides a motor drive base plate riveted structure for circumference and axial bonding strength and circumference positioning accuracy of improvement drive base plate and bearing bracket make the work that the motor can be stable for a long time on the frequent fixed knot of vibration constructs, and rotation accuracy is higher, optimizes the cooperation structure, simplifies motor assemblage technology, reduces manufacturing cost.
The technical scheme of the utility model is that:
the utility model provides a motor drive base plate riveted structure, motor drive base plate riveted structure is based on bearing bracket and drive base plate, wherein, is provided with the mounting hole on the drive base plate, bearing bracket includes a shaft section of thick bamboo and distributes at the outlying installation department of shaft section of thick bamboo one end, shaft section of thick bamboo fixed mounting is in the mounting hole, its characterized in that: the shaft cylinder and the driving substrate are fixed by riveting the fan-shaped part structure and the rib plates on the fan-shaped part structure and the fan-shaped part structure with the driving substrate.
Furthermore, the fan-shaped part structures adopt fan-shaped arc-shaped plates, and a spacing groove is formed between every two fan-shaped part structures.
Further, each rib is identical in structure, shape and size.
Further, the distance between every two ribs is the same.
Furthermore, the rib plates are of a rectangular long plate-shaped structure or a long strip-shaped structure with an arc-shaped curve on the periphery.
The utility model has the advantages that: the utility model discloses a fan-shaped portion structure and the structural floor of fan-shaped portion on the circumference of the lower part of axle section of thick bamboo, with the card hole cooperation back of the inner circle of mounting hole on the drive base plate, again with fan-shaped portion structure and floor to the direction flanging of base plate, the riveting has realized bearing bracket and drive base plate's good fixed.

Detailed Description
As shown in fig. 1-4, a riveting structure for a motor driving substrate is based on a bearing support 1 and a driving substrate 2, wherein a mounting hole 21 is formed on the driving substrate 2, the bearing support 1 comprises a shaft 11 and a mounting portion 12 distributed at the periphery of one end of the shaft, a plurality of fan-shaped structures 13 are arranged on the circumference of the lower portion of the shaft 11, wherein a rib plate 111 is arranged on each fan-shaped structure, the shaft 11 is arranged in the mounting hole 21, and after the rib plate 111 is matched with a fixing hole 211 on the driving substrate 2, the fan-shaped structures 13 and the rib plate are flanged towards the direction of the plane of the substrate, the riveted part of the fan-shaped structures 13 is extruded into the hole wall of the mounting hole 21 of the driving substrate made of softer material due to the ductility of the material, and a spacing groove 112 is formed between each fan-shaped structure 13 and the adjacent fan-shaped structures, after riveting, part of the material of the driving substrate 2 is reserved in the spacing groove 112, so that the driving substrate at the spacing groove 112 forms a convex part, and forms a staggered and spaced fit with a concave part formed at the riveted fan-shaped part structure, thereby strengthening the fixation of the driving substrate, eliminating the fit clearance and improving the fit precision and the fit strength of the motor.
In addition, the fan-shaped portion structure 13 of this embodiment adopts a fan-shaped arc plate, and the two ends of the fan-shaped arc plate are close to each other to form a surrounding plate on the lower periphery of the shaft barrel 1. The rib plates 111 are arranged on the fan-shaped arc-shaped plates, but rib plates are not arranged on each fan-shaped arc-shaped plate, 3-5 rib plates can be arranged on the whole enclosing plate at intervals, and the intervals of the rib plates 111 can be the same or different, so that the rib plates can be arranged on the fan-shaped arc-shaped plates according to actual conditions, and the structure, the shape and the size of each rib plate are the same in the embodiment.
In the present embodiment, the rib plate 111 has a rectangular long plate-like structure or a long structure having an arc-shaped curve on the outer periphery. The strip-shaped structure is just one embodiment of the application, and the curved structure or the irregular structure can meet the matching requirement under certain conditions.
The above embodiments only represent some embodiments of the present invention, and the description is specific and detailed, but not understood as the limitation of the scope of the invention, it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and all of them belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
