AI Technical Summary
The protective shell of existing portable workpiece grinding devices is difficult to disassemble and has a limited range of motion, which can easily obstruct the operator's view when grinding workpieces of different shapes, reduce grinding accuracy and affect work efficiency. At the same time, the fixed protective shell cannot be adjusted according to the grinding angle, which increases the risk of operation.
A portable workpiece surface grinding device was designed, which adopts an adjustable protective shell structure and a folding mechanism. Through the combination of pins, ring rails and buckles, the protective shell can be flexibly adjusted and quickly stored. Combined with adjustable connecting rings and clamps, the operation line of sight is not obstructed, and the folding mechanism enables the device to be portable and stored.
It improves grinding accuracy and work efficiency, reduces operational risks, enhances the flexibility and safety of the equipment, and simplifies the process of maintaining and replacing grinding discs.
