Description

Technical Field

[0001] This utility model relates to the field of shaft reinforcement processing technology, and in particular to a motor shaft reinforcement device. Background Technology

[0002] In the assembly process of motors, the shaft plays a connecting role, and a good and stable connection of motor components is particularly important. Currently, the commonly used shaft punching method can generally process a single rib at a time. When multiple ribs need to be processed, multiple clamping is required, which is inefficient. Moreover, the punching devices currently used are generally asymmetrical designs, and it is necessary to strictly distinguish between the positive and negative directions when using them. In view of the above defects, this application is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a motor shaft reinforcement device that solves the problems of low efficiency in motor shaft reinforcement and inconvenience in using the reinforcement device by distinguishing between the positive and negative directions.

[0004] To solve the above problems, this utility model provides a motor shaft rib-forming device, including a mold sleeve, a release module, and rib-forming knives. Two sets of mold sleeves are arranged symmetrically. Each mold sleeve has a knife mounting position, and several sets of these positions are provided, the specific number depending on the required number of ribs to be formed on the motor shaft. The rib-forming knives are installed in the knife mounting positions. The release module is disposed within the mold sleeve, forming a processing position between the release module and the mold sleeve. The motor shaft to be processed is placed at the processing position, and several rib-forming knives are arranged around the processing position. The release module is connected to an elastic column, which is connected to the mold sleeve. During stamping and mold closing, the elastic column deforms under pressure, ensuring that the rib-forming knives are pressed into the motor shaft to form ribs.

[0005] According to one embodiment of the present invention, the mold sleeve is provided with mounting holes for inserting elastic columns, and three sets of elastic columns are provided, with three sets of mounting holes corresponding to each elastic column.

[0006] According to one embodiment of the present invention, the tool mounting position is a through groove provided on the mold sleeve. The through groove is arranged along the axial direction of the machining position, and the punching tool can be installed at any end of the through groove or at a position therein.

[0007] According to one embodiment of the present invention, the motor shaft filling device further includes an adjustment and limiting component for adjusting the position of the filling cutter.

[0008] According to one embodiment of the present invention, the adjusting limiting component includes a limiting bolt, which is mounted on the mold sleeve.

[0009] According to one embodiment of the present invention, each of the tool mounting positions is provided with a number of sets of limiting bolts.

[0010] According to one embodiment of the present invention, the motor shaft filling device further includes positioning pins. Generally, at least two sets of positioning pins are provided. The positioning pins are installed on the mold sleeve and are used to realize the positioning and fixing of the mold sleeve and the mold frame.

[0011] According to one embodiment of the present invention, the mold sleeve is provided with a mold sleeve positioning structure, which is used to realize the positioning of the mold sleeve and the external equipment. The mold sleeve positioning structure is preferably provided with screw holes on the mold sleeve, and four sets are provided, which are respectively provided at the four corner positions. The positioning and installation of the mold sleeve can be realized by installing bolt assemblies.

[0012] According to one embodiment of the present invention, the tool mounting position is provided in four sets, which can process four ribs at one time.

[0013] According to one embodiment of the present invention, the elastic column is made of rubber or other elastic polymer materials.

[0014] The beneficial effects of this utility model are that, through the symmetrical design of the mold sleeve, this device does not have a distinction between front and back or front and rear, and can realize the front and rear switching of punching, which facilitates the installation and position adjustment of the punching knife, and facilitates the installation of the device and the mold frame. It can improve processing efficiency, practicality and convenience and stability. Moreover, by setting multiple punching knives, the required number of ribs can be processed on the motor shaft at one time, which further improves processing efficiency. Attached Figure Description
