Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic structural view of a reversible belt sander used in a belt grinder according to the present invention.
Fig. 2 is a schematic structural view of a belt sander.
FIG. 1 shows a reduction motor; 2. a main motor; 3. a driving pulley; 4. an abrasive belt; 5. a polishing device; 6. a cylinder; 7. a driven pulley; 8. a frame; 9. a reversible belt sander for a belt sander.
Detailed Description
Referring to fig. 1, a gear motor 1 is connected to a frame 8, and when the gear motor 1 is energized, the gear motor 1 starts to rotate, and the gear motor 1 drives the frame 8 to rotate together. The main motor 2 is arranged on the frame 8, the driving belt wheel 3 is connected with the main motor 2, when the main motor 2 is electrified, the main motor 2 starts to rotate, and the main motor 2 can drive the driving belt wheel 3 to rotate together.
The cylinder body of the cylinder 6 is fixed on the frame 8, the end plate of the cylinder 6 is connected with the driven belt wheel 7, one end of the abrasive belt 4 is arranged on the driving belt wheel 3, and the other end is arranged on the driven belt wheel 7. When a certain pressure of gas is supplied to the cylinder 6, the piston rod of the cylinder 6 extends, that is, the end plate of the cylinder 6 extends, and at this time, the end plate of the cylinder 6 drives the driven pulley 7 to move rightward, so that the distance between the driving pulley 3 and the driven pulley 7 is increased, and the abrasive belt 4 is tensioned. When the gas of the cylinder 6 is cut off, the piston rod of the cylinder 6 retracts, that is, the end plate of the cylinder 6 retracts, and at this time, the end plate of the cylinder 6 drives the driven pulley 7 to move leftward, so that the distance between the driving pulley 3 and the driven pulley 7 is reduced, and the abrasive belt 4 is loosened, and the current abrasive belt can be conveniently taken out from the pulley. The degree of tensioning of sanding belt 4 depends on the pressure of the gas supplied to cylinder 6, the greater the pressure the greater the degree of tensioning and vice versa the smaller the degree of tensioning.
The polishing device 5 is arranged on a slide rail of the frame 8 and can move left and right on the slide rail of the frame 8, so that the polishing part of the workpiece can be conveniently and quickly positioned. Because the slide rail of the frame 8 is longer, the stroke of the grinding device 5 moving on the slide rail of the frame 8 is large, and longer workpieces can be ground.
The frame 8 can realize reciprocating rotation within a certain angle range under the driving of the speed reducing motor 1, and meanwhile, the abrasive belt 4 is turned over together, so that the purpose of continuously polishing a plurality of surfaces of a workpiece can be realized. When the speed reducing motor 1 drives the frame 8 to rotate, so that the abrasive belt 4 is in a horizontal state, the top surface of the workpiece right below the abrasive belt 4 is parallel to the abrasive belt 4, namely the grinding device 5 can grind the top surface of the workpiece; when the speed reducing motor 1 drives the frame 8 to rotate, the abrasive belt 4 is in a vertical state, the main motor 2 faces upwards, the back of a workpiece positioned right below the abrasive belt 4 is parallel to the abrasive belt 4, and the grinding device 5 can grind the back of the workpiece; when the speed reducing motor 1 drives the frame 8 to rotate, so that the abrasive belt 4 is in a vertical state and the main motor 2 faces downwards, the front face of the workpiece right below the abrasive belt 4 is parallel to the abrasive belt 4, namely the grinding device 5 can grind the front face of the workpiece.
