Description of the new model: [Technical field to which the new model belongs] The present invention relates to a polishing machine, especially a polishing machine with a centrifugal quick-stop rotation structure, which has a braking effect and achieves a quick stop of the sanding disc. [Previous technology] For the existing polishing machine, please refer to the new patent case No. 529515 "Improved Structure of Pneumatic Sanding Polishing Machine". Its overall structure is shown in the case. It uses a pressure gas to drive a pneumatic motor inside the polishing machine. The motor drives the eccentric shaft set at its axial position to rotate, and the bottom of the eccentric shaft is eccentrically pivoted with a rotatable sanding disc shaft center, and a sanding disc for polishing is combined with the bottom of the sanding disc shaft center. When the polishing machine is used, the eccentric shaft is driven by a pneumatic motor to rotate, so that the eccentric sanding disc axis oscillates and rotates, thereby the sanding disc combined with the sanding disc axis will reciprocate horizontally and can be used for friction polishing The surface of the object. However, when the polishing machine wants to stop, the air motor stops rotating and has a certain braking effect, which makes the eccentric shaft directly linked to the air motor stop quickly. However, the axis of the rotating sanding disc will continue to rotate for a while, making the sand It takes a period of time for the grinding disc to settle, and waiting for the sanding disc to stop is inconvenient, or someone puts the bottom of the sanding disc to the ground and stops the sanding disc quickly by friction, but this kind of However, this method will cause the wear of the sanding disc, which is not economical and needs to be improved. [New content] 4 M279441 * Because the existing polishing machine has the disadvantage that f is not enough to wait for the sanding disc to stop after use, this creation is a polishing machine with a centrifugal rapid stop rotation structure ± it must be achieved by the design of a brake The function of the sanding disc to stop quickly. To achieve the above purpose, the creative department includes: a polishing machine body; a power motor. The power motor is installed in the body of the polishing machine and extends downward at the bottom axis-an eccentric shaft. The bottom of the eccentric shaft is _counterweight 2 :::, the stomach weight crankshaft is eccentrically pivoted at the bottom-a self-rotating sanding brake state, the brake is combined with the center of the sanding disk shaft bottom: ::: 器It is disc-shaped and has a ring with an outer end edge extending obliquely upwards. The -4 material wing is made of elastic material and has a Moab portion on the top. The friction portion abuts the counterweight crankshaft portion; and "-沙Grinding disc 'A top end of the sanding disc is provided with a stud passing through the center of the brake pad and resting on the core of the sanding disc. ^ Bottom 较佳 The best implementation of this creation, like, # 中 沙 磨盘 轴 轴 成 ， 角 角 板 片 的 联 部 '。 And the brake is provided at the center-a joint portion' the joint portion is on the top surface The corresponding joint part is provided with a fitting groove of ― :, and the fitting groove is fitted to the bottom of the shaft center of the sanding disc :: The wing blades are circular and extend obliquely upward. Moreover, the brake is arranged relatively, and the friction part is concentrically divided into three circles and is dispersed in the brakes: the BH master of the member and cooperates with the diagonally extending brake fins to make the pillars of the inner ring higher and outward. Short circles. M279441 Another preferred setting, the friction part is a rough surface, and the rough surface abuts against the weight crankshaft part. When this creation is used, the power motor is rotated to drive the eccentric shaft to rotate, so that the center of the sanding disc eccentrically set with the eccentric shaft swings back and forth and rotates, so that the sanding disc combined with the center of the sanding disc will be horizontal. Reciprocating movement, and at this time, the brake will generate centrifugal force with the rotation and swing, so that the surrounding and elastic brake fins will be extended outward to become horizontal, and the friction part will leave the counterweight crankshaft part without braking effect. . When the power motor stops operating, the brake fins of the brake will lose centrifugal force at this time, so the brake fins will return to the original position on the outer periphery. 'The friction part is pressed against the counterweight crankshaft of the centrifugal shaft, so that the disc shaft is sanded. The center and the eccentricity are linked to the relative braking of the shaft. The braking effect of the power motor is used to make the sanding disc not to be static due to rotation, but to stop at the same time as the eccentric shaft. Spinning brake effect.
