Description

A kind of corner sand polishing machine

technical field

The utility model relates to a polishing, in particular to a corner sand polishing machine.

Background technique

The corner sand used by the existing corner sand polishing machine adopts emery cloth rolls to make 12.7CM octagonal sand, which is divided into eight sand corners on the round sand block as shown in Figure 5, and is divided vertically along the middle of each sand corner. Fold the line in half, so that the desired corner sand is made. There is a through hole in the middle of the round sand block, and a circular iron pressure plate with a diameter less than 10CM is installed at both ends of the transmission shaft, and the middle part of the two circular iron pressure plates on the transmission shaft is installed with a diameter greater than or equal to 12.7CM. Round octagonal sand, one end of the circular iron pressure plate is screwed on the axis with a hexagonal nut to fix and compress the circular octagonal sand in the middle of the two circular iron pressure plates. When the motor rotates, the circular belt on the drive shaft Star anise sand to polish the object. When such a corner sand is polished, it is folded in half along the other vertical line of the sand corner, and another corner sand is obtained. Therefore, each round sand block can only be used twice, and the main usage rate is not high. The 12.7CM round sand block must first be cut out from the square emery cloth, and a 25MM round hole must be cut in the middle.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figures 1 to 4 and 7, the utility model includes a frame and its shell, on which a sand polishing assembly is arranged, and the sand polishing assembly includes a sand wheel and its sand fixing seat, power components. A polished tabletop height-adjusting assembly is arranged in the frame, and the polished tabletop assembly is connected with the polished tabletop height-adjusting assembly. The sand piece fixing seat in the sand piece polishing assembly comprises a cylinder and is formed, and the cylinder is formed and is fixed on the frame through the connecting block bearing 2. One end of the cylinder composition is provided with a transmission wheel 3, and the other end of the cylinder composition is provided with an emery wheel. Transmission wheel 3 links to each other with polishing motor 4 through a belt.
