AI Technical Summary

Technical Problem

The existing linear motor devices used in FANUC machine tools have poor heat dissipation capabilities, resulting in a reduced service life and a lack of an effective limit buffer structure, resulting in poor safety of the workbench.

Method used

A linear motor device including a heat dissipation assembly and a limit buffer structure is designed. The heat dissipation assembly forms an airflow channel through supporting plates, heat sinks and fans, so as to dissipate heat from below. The limit block and cushion pad are used to prevent the workbench from breaking away from the bed and to cushion the force when impacted.

Benefits of technology

It effectively improves the heat dissipation effect of linear motors, extends service life, and improves the safety of the workbench through the limit buffer structure, avoiding the risk of leaving the bed.

Abstract

The utility model relates to the technical field of linear motors, and discloses a linear motor device for a FANUC machine tool, which comprises a machine tool body, linear guide rails are fixedly arranged on two sides of the upper end surface of the machine tool body, a mounting groove is arranged on the upper end surface of the machine tool body and located between the two linear guide rails, and a heat dissipation assembly is arranged on the machine tool body through the mounting groove. A stator is arranged at the upper end of the heat dissipation assembly, a rotor is arranged above the stator, and a workbench is arranged on the surface of the upper end of the rotor. According to the linear motor device for the FANUC machine tool, the heat dissipation assembly is arranged, the draught fan works, external air is sucked into the airflow channel, air can take away internal heat through the airflow channel, then enters the first side frame and is finally exhausted to the outside through the draught fan, heat dissipation is conducted on the linear motor from the lower portion, the heat dissipation effect is guaranteed, and the service life of the linear motor is prolonged. The service life of the linear motor is prolonged.
