Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.

In the related art, when a motion shaft moves at a high speed on a machine table, the inertia is large, the shaking condition of the whole machine is easy to occur, if shaking or vibration of the motion shaft is directly absorbed through strengthening the structural strength of the whole machine, the weight of equipment is heavy, and the installation and the debugging are not facilitated.

In order to solve the above technical problems. Referring to fig. 1-3, the present embodiment provides an inertia canceling mechanism disposed on a machine 100 for canceling motion inertia of a motion axis 101 disposed on the machine 100. The inertia counteracting mechanism of this embodiment includes a linear motor 1 and a counterweight 2, the linear motor 1 is detachably disposed on the machine 100, the proceeding direction of the linear motor 1 is opposite to the moving direction of the moving axis 101 (the moving direction during operation, the actually configured linear motor is a reciprocating motion, and the reciprocating motion direction and the moving axis are coaxially disposed), and the counterweight 2 is detachably disposed on the linear motor 1.

It can be understood that by adding the linear motor 1 to the machine 100, the linear motor 1 synchronously performs the linear motion opposite to the motion direction of the motion axis 101 while the motion axis 101 performs the linear motion, so as to effectively offset the inertia generated by the motion axis 101 under the high-speed motion. The balancing weight 2 is additionally arranged on the linear motor 1, so that the shaking of the machine 100 is reduced, and the equipment can be ensured to run safely and at a high speed. Wherein, the linear motor 1 is detachably mounted on the machine 100, the balancing weight 2 is detachably mounted on the linear motor 1, and the mounting position of the linear motor 1 on the machine 100 or the weight of the balancing weight 2 mounted to the linear motor 1 is adjusted to facilitate the mounting or debugging operations of the equipment.

Of course, in actual production, the travelling speed of the mover 13 of the linear motor 1 and the weight of the balancing weight 2 need to be determined according to the specific arrangement of the moving shaft 101 on the machine 100, and are not limited to the above-mentioned preferable adaptation relation, and the linear motor is easy to implement and has good practicability.
