Eccentric block device with built-in outer rotor servo motor

Abstract

The invention provides an eccentric block device with a built-in outer rotor servo motor, relates to the technical field of mechanical tools, and aims to solve the problems that a convenient counterweight structure and a buffer adjustment balance structure are not mounted in an original eccentric block, so that the eccentric block reduces the rotating vibration force of the built-in outer rotor servo motor; meanwhile, the functions of freely adjusting the eccentric block to increase and decrease the gravity are reduced, the eccentric block can not utilize an external structure to buffer the inertia of rotation, the buffering function of the eccentric block for freely balancing rotation or stopping is reduced, and meanwhile the practicability of the eccentric block is reduced. The eccentric block device comprises a fixing structure, and adjusting structures are installed at the inner ends of the outer sides of the fixing structures in a penetrating manner. Due to the fact that a fixing groove is of the irregular annular structure, the protruding cylindrical outer stand columns are fixedly installed on the outer side faces of the lower end of the fixing groove respectively, and the eccentric block can be conveniently used when rotating through the special shape of the fixing groove.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, and more specifically relates to an eccentric block device with a built-in outer rotor servo motor. Background technique [0002] Install a set of adjustable eccentric blocks at both ends of the rotor shaft, and use the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks to obtain the exciting force. One of the eccentric block devices with a built-in outer rotor servo motor can increase the vibration frequency range of the servo motor. The mechanical noise can only be reduced if the excitation force and power are properly matched, and an eccentric block device with a built-in outer rotor servo motor can also perform proper buffering and balance the inertia generated by the rotation when stopping, thereby increasing the practicability of the servo motor. [0003] For example, the patent No. CN111509900A, the invention belongs to the technical field of ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides an eccentric block device with a built-in outer rotor servo motor to solve the problem that the original eccentric block does not have a convenient counterweight structure and a buffer adjustment balance structure, resulting in a reduction in the built-in eccentric block. The rotation and vibration of the outer rotor servo motor also reduces the free adjustment of the eccentric mass to increase or decrease the gravity function, and the eccentric mass cannot use the external structure to buffer the inertia of the rotation, which reduces the free balance rotation or rotation of the eccentric mass. The buffer function of the stop, while reducing the practicality of the eccentric block
