Description

A mold for eliminating uneven thickness of motor iron core

technical field

The utility model relates to the stamping field, in particular to a mold for eliminating the uneven thickness of the iron core of a motor.

Background technique

The motor iron core in the existing market is stamped by a die into laminations and superimposed. Since each lamination often has a certain thickness difference during stamping, it is easy to cause uneven thickness of the superimposed motor core, thereby affecting the accuracy of the motor.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a mold that eliminates the uneven thickness of the motor iron core. The stamping rotates at a certain angle each time, thus eliminating the problem of uneven thickness of the motor core.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a mold for eliminating the uneven thickness of the iron core of the motor, including a workbench; the workbench is provided with a vertically placed and rotatable rotating shaft sleeve, and the The workbench is also provided with a motor connected to the rotating shaft sleeve through a synchronous belt drive; the upper end of the rotating shaft sleeve is provided with a fixedly connected blanking lower die.

Preferably, the motor is a servo motor.

Preferably, the workbench is also provided with a tensioning pulley for tensioning the synchronous belt drive.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The mold for eliminating the uneven thickness of the motor iron core described in the utility model will drop the punched iron core laminations into the blanking lower mold in turn, and the blanking lower mold will rotate at a certain angle with the stamping each time, thereby eliminating the need for motors. The problem of uneven core thickness.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Accompanying drawing 1 is the structural representation of the mold for eliminating uneven thickness of motor iron core described in the utility model.

Among them: 1. Motor; 2. Workbench; 3. Tensioner wheel; 4. Synchronous belt drive; 5. Blanking lower die; 6. Rotating sleeve; 7. Bearing.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1 is the mold that eliminates the uneven thickness of motor iron core described in the utility model, comprises the workbench 2 that places horizontally; Described workbench 2 is provided with vertically placed and rotatable rotating shaft sleeve 6, wherein rotates The shaft sleeve 6 is connected to the workbench 2 through a bearing 7, and one side of the workbench 2 is also provided with a motor 1 connected with the rotating shaft sleeve 6 through a synchronous belt transmission 4, and the workbench 2 is also provided with a tensioning synchronous The tensioning wheel of the belt transmission 4 prevents the synchronous belt from loosening after long-term use and affects the transmission accuracy; the motor 1 is a servo motor, which can ensure the rotation angle and speed of the rotating shaft sleeve 6; the upper end of the rotating shaft sleeve 6 is set There is a blanking lower die 5 which is fixedly connected and can automatically superimpose laminations after stamping.

When in use: After each stamping is completed, the servo motor drives the rotating sleeve 6 to rotate at a certain angle through the synchronous belt drive 4. Since the blanking lower die 5 is fixed on the rotating sleeve 6, it will rotate with the rotating sleeve 6, and each The laminations of the sheet iron core are placed in different positions, thus eliminating the problem of uneven thickness of the motor iron core.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The mold for eliminating the uneven thickness of the motor iron core described in the utility model will drop the punched iron core laminations into the blanking lower mold in turn, and the blanking lower mold will rotate at a certain angle with the stamping each time, thereby eliminating the need for motors. The problem of uneven core thickness.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
