Description

Technical Field

[0001] The utility model relates to a device for motor production, in particular to an eccentric wheel installation device for a motor. Background Art

[0002] A motor is a commonly used energy conversion device. The motor generates mechanical energy by rotating the output shaft. By controlling the rotation mode of the motor, various working actions can be achieved. Installing an eccentric wheel on the output shaft of the motor and swinging the eccentric wheel can achieve working requirements such as vibration and intermittent driving. Therefore, an efficient way to install the eccentric wheel needs to be realized. Due to the eccentric characteristics of the eccentric wheel, its centroid and axis are not collinear. Conventional installation equipment mostly installs through coaxial stamping equipment, and the pressure applied to the installation of the eccentric wheel is skewed and uneven. Therefore, improvements are needed to meet the requirements of eccentric wheel installation. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies existing in the prior art, and to provide an eccentric wheel installation device for a motor.

[0004] The technical solution adopted by the utility model to solve the above problems is: The installation device includes a stamping machine, the stamping machine includes an upper punch and a lower base. An elastic punch is installed on the upper punch, and a positioning backrest and an eccentric wheel positioning seat are arranged on the lower base. The elastic punch is arranged corresponding to the rear end face of the motor. The positioning backrest forms the outer shape of the side of the motor. The eccentric wheel positioning seat is arranged opposite to the elastic punch. An eccentric wheel placement hole is arranged at the upper part of the eccentric positioning seat. The side of the motor is positioned by the positioning backrest and its shaft end corresponds to the eccentric wheel on the eccentric positioning seat, and is installed and fixed with the eccentric wheel under the pressure of the elastic punch. The elastic punch presses the rear end face of the motor and generates an installation impact force. The eccentric wheel is stably positioned at the position where it needs to be installed, ensuring the concentricity of the installation, effectively avoiding skew, and improving the installation quality.

[0005] Further, the elastic punch includes a fixed column, a socket joint and a spring. The fixed column is fixedly arranged on the upper punch. The lower end of the fixed column is formed into an axial center top. The socket joint is sleeved on the axial center top. The lower bottom edge of the socket joint corresponds to the rear end face of the motor. A spring is elastically pressed between the fixed column and the socket joint, and the spring presses the socket joint downward. The fixed column is a relatively fixed part, and the axial center top formed at its lower end can tightly press the shaft end of the motor, and has better installation punching force during stamping. The socket joint can apply pressure to the end face of the motor, ensuring uniform pressure on the motor in the end face direction and ensuring the installation accuracy.

[0006] Furthermore, the positioning backrest includes a backrest body. A profiling surface that imitates the outer shape of the side of the motor is formed on the side of the backrest body. The motor is restricted from lateral swing within the profiling surface. An installation hole is formed on the positioning backrest, and a fixing nail is connected to the installation hole and connected to the lower base. The profiling surface formed by the positioning backrest can quickly and conveniently perform positioning, improving the installation efficiency. The positioning backrest can be adapted and replaced according to the outer shape of the motor, improving the working adaptability of the structure.

[0007] Furthermore, the eccentric wheel positioning seat includes a positioning body. The upper part of the positioning body is formed with the eccentric wheel placement hole. A receiving cavity is formed in the lower part of the eccentric wheel placement hole. The edge of the main body part of the eccentric wheel is aligned with the eccentric wheel installation hole, and the offset part of the eccentric wheel is arranged in alignment with the receiving cavity. The docking installation hole of the eccentric wheel is coaxially aligned with the axis of the motor. The receiving cavity is provided in the lower part of the positioning body, which can align the offset part of the eccentric wheel, achieving the effect of aligning the axis of the eccentric wheel and effectively improving the positioning and installation accuracy.

[0008] Furthermore, a balance plate is provided on the upper punch of the stamping machine. A guide sleeve is provided on the balance plate. The guide sleeve is cooperatively provided with a guide post. The bottom of the guide post is fixed on the lower base. The balance plate moves up and down horizontally along the guide post, and the elastic punch head is fixed on the balance plate. The balance plate can maintain the linear accuracy during the stamping process. During the stamping operation, it can effectively improve the installation accuracy of the eccentric wheel and improve the product quality.

[0009] Compared with the prior art, the present utility model has the following advantages and effects: This design is an installation device for the eccentric wheel structure of a motor, which can respectively position the motor body and the eccentric wheel, and cooperate with the operation of the stamping machine to quickly perform stamping and alignment installation, effectively improving the product installation accuracy and the installation efficiency.
