Grinding machine

Abstract

The invention relates to a grinding machine which comprises a base and a grinding machine body installed on the base. A motor is arranged in the grinding machine body. An output shaft of the motor stretches out of the grinding machine body, and a grinding wheel is fixed to the output shaft of the motor. A support is fixed to the base and comprises a vertical rod and a horizontal rod. The horizontal rod is in threaded connection with a stand rod. The bottom end of the stand rod is detachably connected with a clamp assembly. The clamp assembly comprises a support seat and a clamp seat connected with the support seat. The clamp seat comprises a circular truncated cone shaped seat and a barrel-shaped seat which are integrally formed and arranged up and down. At least two adjusting bolts are arranged on the circumference of the barrel-shaped seat. According to the grinding machine, a workpiece is installed in the barrel-shaped seat, and the height of the stand rod can be adjusted by rotating the stand rod, so that pressure between the workpiece and the grinding wheel is adjusted to guarantee the smooth proceeding of grinding. The outer diameter of a first cylindrical seat is greater than that of a second cylindrical seat; when the workpiece in the barrel-shaped seat needs to be replaced, the first cylindrical seat is supported by a replacement platform by rotating the barrel-shaped seat, supporting is stable and firm, and shaking is avoided.

Description

technical field [0001] The invention relates to an electric tool, in particular to a grinding machine. Background technique [0002] Grinding machines are widely used in the finishing and surface polishing of workpieces. The existing grinding machines include fixed grinding machines and mobile grinding machines. The fixed grinding machine is fixed on the base, and then the workpiece is placed on the grinding wheel for grinding. However, the existing The fixed grinding machine cannot adjust the distance between the workpiece and the grinding wheel, and cannot adjust the pressure, so that the grinding quality is poor, the application range is narrow, and the cost is high. The mobile grinding machine is manually held in the hand to grind the workpiece. As time goes on, the hand will be sore and fatigued, which will reduce the grinding efficiency. At the same time, there may be accidents, which is very unsafe. Contents of the invention [0003] The invention overcomes the sho...

[0002] Grinding machines are widely used in the finishing and surface polishing of workpieces. The existing grinding machines include fixed grinding machines and mobile grinding machines. The fixed grinding machine is fixed on the base, and then the workpiece is placed on the grinding wheel for grinding. However, the existing The fixed grinding machine cannot adjust the distance between the workpiece and the grinding wheel, and cannot adjust the pressure, resulting in poor grinding quality, narrow application range, and high cost

The mobile grinding machine is manually held in the hand to grind the workpiece. As time goes on, the hand will be sore and fatigued, which will reduce the grinding efficiency. At the same time, there may be accidents, which is very unsafe.
