With a fixing bolt 237 f locked to the fixing block 231, the screw hole 231 of the sleeve hole 2312 is 5 M415780. When the surface of the workpiece 3 is polished by the composition of the above components (such as the eleventh As shown in the figure, 'the height of the plurality of adjustment mechanisms supporting the platform 15 is adjusted according to the diameter of the workpiece 3 (as shown in FIG. 14), and the adjustment mechanism 17 is fixed to the body 1 The fixing base 171 is composed of a supporting column 172 connected to the bottom of the platform 15. One side edge of the fixing seat 171 is fastened by a quick release handle 173' having a locking thread 174. And the structure of the release (the structure of the quick release handle 173 is a conventional technique, so it will not be described again), and the platform 15 can be provided according to the height required for the workpiece 3 • rapid adjustment to adjust its position, and at the same time cooperate a lateral displacement of the limiting seat 151 on the platform 15 to limit the forward direction of the workpiece 3, and adjust the position of the adjusting wheel 23 on the third mounting hole 2〇4 (as shown in FIG. ) to make the belt gap between the two belts B w can be ground to the peripheral edge of the workpiece 3. When the grinding operation is started, the motor U is started, and the rotating disk 20 is driven by the transmission of the belt p. Since the inner surface 24 does not rotate, the gear portion 2 (5) of the driving wheel is combined with the inner teeth 24133 to make the active The wheel 21 rotates along the inner toothed disc on the one hand, and the other & _ difference is driven by the elastic belt 22 and the adjusting wheel 23 by the cymbal belt 4 (as shown in the tenth and tenth drawings), the H bump 20 and the abrasive belt The relationship between the rotations of the planets is generated between the wheel sets B, so that the addition of the members 3 to the straight line advances in the raft, and the abrasive belt 4 can be used as the surface polishing of the entire circumference, so that the operator is time-saving and labor-saving, and the workpiece 3 The surface grinding is more evenly smooth, so it can effectively solve the lack of the formula. The eleventh figure is a schematic diagram of the replacement of the abrasive belt 4 for the creation. When the abrasive belt 4 needs to be replaced when it is purified or worn, the fixed block 220 of the elastic wheel 22 is pushed forward with the finger* The abrasive belt 4 is in a relaxed state, P removes the abrasive belt 4, and then replaces the new abrasive belt 4 around the 6 driving wheel 21, the elastic wheel 22, the adjusting wheel 23, and then opens the auger 7 to the hair, at this time the spring 22δ will push back the elastic wheel 22 against the abrasive belt 4 with its returning elastic force, and the J-added abrasive belt 4 will be installed. The bottom of the grinding device 本 of the above-mentioned creation is the sputum and the dander to 13, and the swarf chamber collects the grinding debris, which is further transmitted through the pumping tube 14 on the side of the machine 10 for 7 π, and can discharge the debris. Externally. In summary, the 'this solution is mixed with the difficulty wheel and the driving wheel _ planetary revolving motion' to drive the belt on the two belt pulleys, and the surface of the workpiece is polished to achieve rapid processing and Obtain the average sentence of the throwing surface to solve the missing of the formula.
