Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Figures 1 to 9, a grinding machine with a detachable sanding head includes a main body 1 and a sanding head for grinding the surface of a workpiece. The main body 1 includes a casing and is used to drive the sanding head The drive motor, the drive motor is located in the casing, the grinding machine also includes a quick disassembly structure, the quick disassembly structure includes a button 3 for quick disassembly of the sanding head, the button 3 includes a first pressing piece and a second pressing piece, the first pressing piece is arranged opposite to the second pressing piece, and the casing is provided with a first fulcrum 10 and a second pressing piece on the side facing the sanding head. Two fulcrums 11;

The middle and rear part of the first pressing piece is hinged on the first fulcrum 10, the middle and rear part of the second pressing piece is hinged on the second fulcrum 11, and the compression spring 4 used to reset the button 3 is arranged on the first fulcrum. Between the front of a pressing piece and the front of the second pressing piece, the left end of the compression spring 4 touches on the first pressing piece, and the right end of the compression spring 4 touches on the second pressing piece. on the pressing sheet;

The rear end of the first pressing piece is provided with a first hook, the rear end of the second pressing piece is provided with a second hook, and the first hook is arranged opposite to the second hook. The sanding head is respectively provided with a first slot matching with the first hook and a second slot matching with the second hook on a side facing the casing.

Further, the sanding head is a sanding disc, and the sanding disc is a circular sanding disc 30 or a triangular sanding disc 20. Of course, the sanding head can also be a sanding rod or a sanding ball, and the shape of the sanding disc can also be other shapes.

Still further, the grinder also includes a dust suction system for dust suction, the dust suction system includes a dust suction cover 2, a fan, a dust separator and an air duct, and the fan is connected to the fan power drive device, so Both the dust separator and the fan are located in the dust suction hood 2, and the dust suction hood 2 is installed on the casing.

Furthermore, the dust suction hood 2 is located between the casing and the sanding head, and the dust suction hood 2 is provided with the first fulcrum 10 and the sanding head on the side facing the sanding head. The second fulcrum 11, the sanding head is respectively provided with a first slot matching with the first hook and a second slot matching with the second hook on the side facing the dust suction cover 2. Two card slots.

In this embodiment, the dust suction system also includes a dust suction port 6 and a dust discharge port 7. At least one of the dust suction hood, the dust separator and the fan is connected through an air duct, and the dust is removed from the dust suction hood by the fan. The dust suction port 6 is transported to the dust separator for air and dust separation. The fan power drive device includes a drive motor. The drive motor and the fan are driven by a pair of gears. The dust suction fan blade is installed on the driven shaft of the gear to absorb dust.
