A protective frame for the frequency converter of a grinder

Abstract

The invention discloses a protective outer frame for a frequency converter of a grinding machine, including an outer frame, the front side of the outer frame is provided with an opening, first fixed springs are uniformly distributed and fixedly connected on the bottom surface of the inner cavity of the outer frame, the tops of the first fixed springs are fixedly connected with a first support plate, the top surface of the first support plate is provided with a first fixing clamping groove, second fixing springs are uniformly distributed and fixedly connected on the top surface of the inner cavity of the outer frame, and the bottom surfaces of the second fixing springs are fixedly connected with a second support plate. The invention relates to the technical field of frequency converter protection equipment. The invention relates to the protective outer frame for the frequency converter of the grinding machine, achieves the purpose of prolonging the service life of the frequency converter, which can effectively cushion and damp the vibration of the frequency converter and play an effective dust-proof role, and the frequency converter can be clamped and fixed on the surface of the grinding machine by using the outer frame, so that the frequency converter is convenient to dismounted from and mount on the surface of the grinding machine, and the frequency converter is not easy to damage and convenient to use.

Description

technical field [0001] The invention relates to the technical field of frequency converter protection equipment, in particular to a protective outer frame for a grinding machine frequency converter. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking Unit, drive unit, detection unit, micro-processing unit, etc. The inverter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, the inverter also has many protection functions, such as overcurrent, overvoltage, overload protection, etc...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a protective outer frame for the frequency converter of the grinding machine, which solves the problem that the existing frequency converter for the grinding machine is generally directly installed on the grinding machine, which is inconvenient to disassemble, and due to the The machine is constantly vibrating during use and a lot of dust is likely to accumulate in the inverter during the grinding process. Long-term use is likely to cause damage to the inverter and its internal parts, which is not conducive to prolonging its service life.
