[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a polishing machine deceleration structure, which further enhances the deceleration effect at the time of rotation of a polishing part and lowers the manufacturing cost. It also reduces the overall weight and the assembly process.

[0002]

[Prior art]

 A general polishing machine is composed of a fuselage, a flat plate, a polishing part, and a plurality of friction parts. Among them, a motor is installed inside the body, and an output shaft is connected to a drive shaft of the motor. Then, this output shaft extends to the outside of the machine, and the output shaft rotates with the rotation of the drive shaft in the motor. A ring-shaped flat plate is fixedly mounted on the body around the output shaft. The back of the polished part is fixed to the fixed base with screws, and the front has a cutting blade. A plurality of slots are formed around the fixing table, and holes are formed in the bottom of the slots. The friction part is made of a material having a low coefficient of friction (eg, Teflon, plastic, etc.), and the friction part has an elongated curved shape, and the width is a width in which the above-mentioned slot enters. is there. At one end of this friction part, a through hole is opened. The method of assembling the friction part and the fixing base is to insert one end of the friction part into the groove hole.After aligning the two parts, insert them into the two holes at the same time with a screw, tighten the screw with a nut, and insert It is to be fixed in the hole. When the abrasive part is connected to the output shaft extending to the outside of the fuselage, the curved protruding part of the friction part comes into contact with the flat plate with an appropriate pressing force. At this time, when the polishing part is rotationally driven, the friction part also rotates with the rotation, and a frictional force is generated between the friction part and the flat plate, thereby reducing the rotation speed of the polishing part.

[0003]

[Problems to be solved by the invention]

 However, in this type of polishing machine, since the curved projections of the friction parts have an elastic structure, if the elasticity is weakened, the friction parts are easily tilted and cannot be controlled at the height of the projections. However, the frictional force generated between the plate and the flat plate is limited, and the rotational speed of the polished part cannot be reduced. For this reason, the present invention is to improve the above-mentioned drawbacks of the polishing machine deceleration structure.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the polishing machine speed reduction structure of the present invention has the following features. The friction component has a stable structure, and the flat plate contact surface becomes wider. When the abrasive part rotates, a more favorable frictional force is generated between the flat plates due to the structure of the friction part, and the deceleration effect of the abrasive part can be achieved. In addition, the friction parts of the present invention are designed without using elastic pieces and are made of corrugated protrusions, so that the manufacturing cost is reduced and more economical. The friction parts are made of corrugated protrusions and are integrally formed with the fixed base. Therefore, the assembly process is simplified. In the present invention, a body and a polishing part are included, and a ring-shaped flat plate having an output shaft as a center is fixed to the body, and a fixing base is fixed to the back of the polishing part. In addition, there are frictional parts in the shape of corrugated protrusions around the fixed base, making this frictional part structure more robust and durable. Since the friction part is in contact with the flat plate more widely, when the polishing part rotates, the friction part exerts a better frictional force together with the flat plate, and the deceleration effect of the polishing part can be achieved.

[Embodiment]

 Hereinafter, embodiments of the polishing machine deceleration structure of the present invention will be described with reference to the drawings. First, as shown in FIGS. 1 to 3, the present invention includes a fuselage 1, a flat plate 2, an abrasive part 3, and a plurality of frictional parts 32. Among them, a motor is built in the fuselage 1, and the driving of the motor is performed. An output shaft 11 is connected to the shaft, and the output shaft 11 extends out of the body 1. The output shaft 11 is rotated by driving a drive shaft of a motor. A ring-shaped flat plate 2 is fixedly installed on the fuselage 1 around the output shaft 11, and the flat plate 2 has a flat surface. A fixed base 31 is installed on the back side of the polished part by a screw method, and a cutting blade 34 is installed on the front side. The cutting blade 34 is preferably a sandpaper blade. A plurality of screw holes 312 are provided around the ring of the fixed base 31. The friction parts should be made of a material with a low coefficient of friction (for example, Teflon, plastic, etc.). The friction component 32 has a corrugated projection around the ring, surrounds the outside of the fixed base 31, and is connected to the fixed base 31 to be integral therewith. A plurality of screws 311 are fixed to the back surface of the polishing part 3, and a plurality of screw holes 312 are formed around the ring of the fixing base 31. Then, the fixing table 31 is fixed to the back surface of the polishing component 3.

When the polishing part 3 is installed on the output shaft 11 extending from the outside of the machine body 1 by the above-described structure, the corrugated projection part of the friction part 32 and a wide area around the friction part 32 come into contact with the flat plate 2. At this time, when the polishing part 3 rotates, the friction part 32 also rotates accordingly. A frictional force is generated between the frictional component 32 and the flat plate 2 to reduce the transmission speed of the polishing component 3. With the friction component structure of the present invention, it is more robust, has a higher friction effect, and the assembly process is reduced.

[0007]

[Effect of the invention]

 As described above, the polishing machine deceleration structure of the present invention includes a body and a polishing part, on which a ring-shaped flat plate centering on the output shaft is fixed, and on the back surface of the polishing part. The table is fixed. Around the fixed base there are corrugated projection-shaped friction parts, which make this friction part structure more robust and durable. Since the friction component is in contact with the flat plate even more widely, when the polishing component rotates, the friction component exerts a better frictional force together with the flat plate, so that the deceleration effect of the polishing component can be achieved. Thereby, the deceleration effect at the time of rotation of the polishing part is further increased, and the manufacturing cost is reduced. It is also effective in reducing the overall weight and the assembly process.
