Power swing arm mechanism of cutting machine and cutting machine

Abstract

The invention provides a power swing arm mechanism of a cutting machine and the cutting machine, and relates to the technical field of cutting machines. The power swing arm mechanism of the cutting machine comprises a motor, a handle, a swing arm, a driving wheel, a driven wheel and a transmission belt. The motor is arranged in the dry cabin; a rotating shaft of the motor provides power for rotation of the cutting blade through the driving wheel, the driven wheel and the transmission belt; the motor is rotationally connected with the cutting machine, the motor can be pushed to rotate through the handle fixed to the motor, the swing arm fixed to the motor is driven to rotate, the set angle of the swing arm is changed, meanwhile, the driven wheel is rotationally arranged on the swing arm, and when the angle of the swing arm is changed, the position of the driven wheel is directly driven to change; the position of the cutting blade fixed on the driven wheel is changed, the cutting function of the cutting machine is achieved, meanwhile, the problem of dynamic sealing of holes in the prior art is avoided, the blocking effect on corrosive water mist is achieved, and the overall service life of the cutting machine is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting machines, in particular to a power swing arm mechanism of the cutting machine and the cutting machine. Background technique [0002] The cutting of metallographic samples is grinding of cutting discs, and the temperature of the slit is high. In order to ensure the original metallographic structure of the sample, cooling liquid is usually used to cool down. The introduction of cooling liquid will put forward higher requirements for the corrosion resistance of the equipment. [0003] Generally speaking, metallographic cutting machines are divided into dry and wet positions. The wet cabin is used to spray coolant and perform cutting tasks; the dry cabin is used to install electronic control components. The cutting motor is the main power source, the power is relatively large and the volume is relatively large. The installation position of the motor determines the technical direction of the cutting m...

AI Technical Summary

Problems solved by technology

This design can transfer the motor from the wet cabin with high humidity to the dry cabin, which improves the reliability of the motor, but the problem is that the deflection track of the power end is a circular arc, so the dry and wet separation plate should be left in a circular arc shape. Hole, the dynamic sealing of the hole is difficult, there will always be corrosive water mist escaping into the dry compartment, and in the long run, causing damage to the motor and electrical components
