Grinding device

Abstract

The invention relates to a grinding device. The grinding device comprises a base and a grinding body mounted on the base, wherein a motor is arranged inside the grinding body; an output shaft of the motor stretches out of the grinding body; a grinding wheel is fixed to the output shaft; a vertical rod is fixed to the base; the vertical rod is connected with a transverse rod through a first hinge pin; a spring and a pull rope are connected between the vertical rod and the transverse rod; the spring is positioned above the pull rope; the transverse rod is connected with a clamping assembly through a second hinge pin; the clamping assembly comprises a support and a clamping seat connected with the support; the clamping seat comprises a truncated cone-shaped seat and a cylinder-shaped seat which are arranged up and down and are integrally formed; and at least two adjusting bolts are arranged on the circumferential surface of the cylinder-shaped seat. According to the grinding device, the transverse rod is pressed or lifted upwards according to workpieces of different thicknesses, the pressure between the workpieces and the grinding wheel is adjusted to the required value, and the smooth implementation of grinding is guaranteed; and the outer diameter of a first cylindrical seat is larger than the outer diameter of a second cylindrical seat, the first cylindrical seat can be supported on a changing platform, supporting is stable, and shaking is avoided.

Description

technical field [0001] The invention relates to an electric tool, in particular to a grinding device. Background technique [0002] Grinding devices are widely used in finishing and surface polishing of workpieces. Existing grinding devices include fixed grinding devices and mobile grinding devices. The fixed grinding device is fixed on the base, and then the workpiece is placed on the grinding wheel for grinding. However, the existing The fixed grinding device cannot adjust the distance between the workpiece and the grinding wheel, and cannot adjust the pressure, so that the grinding quality is poor, the scope of application is narrow, and the cost is high. The mobile grinding device is manually held in the hand to grind the workpiece. As time goes on, the hand will be very 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 shortcoming...

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

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