New description: 【New technical field】 ^ This department is about the improvement of the transmission mechanism of the grinding machine. It is designed to let the user change the grinding form according to the force of the force, such as coarse grinding or fine grinding. It is not necessary to replace different grinders to increase the versatility of the grinder. I [Prior Art] - As shown in the first figure, it is a kind of grinding machine commonly used for surface grinding processing. A similar conventional grinding machine mainly provides grinding disc 20 rotation by a motor 10 driven by electric power or pressure gas. The kinetic energy of the grinding disc 20 is mounted on the bottom of a counterweight eccentric shaft 30, and is coupled to the transmission shaft (not shown) of the motor 10 through the counterweight eccentric shaft 30, so that the grinding disc 20 can be subjected to the counterweight eccentric shaft. The transmission of 30 and then any track eccentrically rotates to achieve the effect of grinding the surface of the sanding workpiece. φ In addition, during the actual surface sanding process of the workpiece, it may be combined with different grinding forms, such as coarse grinding or fine grinding, depending on the material of the workpiece, the abrasive used or the material of the grinding disc itself. Grinding form; however, since the transmission mechanism used in the above-mentioned grinding machine is directly mounted on the counterweight eccentric shaft, the grinding disc can only be made in a single form under the transmission of the counterweight-mandrel. Rotation, if you want to change the grinding form, you must replace another grinding machine for grinding, which will greatly reduce the practicability and applicability of the overall grinding machine. 5 M339612 [New content] In view of this, this creation is to improve the transmission mechanism of the above-mentioned conventional grinding machine, so that the user can change the grinding shape according to the magnitude of the force, such as grinding or fine grinding. The versatile use of the mill. In order to achieve the above, the transmission mechanism of the present invention includes a counterweight eccentric shaft, a mandrel, a brake pad, a pressure plate and a grinding disc, and the main transmission of the counterweight eccentric shaft motor, the mandrel system A grinding disc is arranged below the counterweight eccentric shaft, and the brake disc and the pressure plate are sequentially arranged on the mandrel, and the pressure plate and the brake pad can float up and down relative to the counterweight eccentric shaft. When the motor is actuated to make the counterweight eccentric shaft reach the predetermined rotation speed, the pressure plate and the brake pad are pressurized to a position close to the bottom surface of the weight of the counterweight eccentric shaft due to the centrifugal force, so that the grinding disc and the counterweight eccentric shaft Concentric high-speed rotation, at this time the grinder can grind the workpiece in a rough grinding form. Right to change the grinding form of the rough grinding, the grinding disc is pressed toward the side of the workpiece, so that the grinding shaft is added to the pressure of the slave to resist the rotation, so that the rotation speed is reduced, and the pressure plate is returned to the unbiased shaft with the counterweight. The close-position abrasive is connected to Wei heavy eccentricity. (4) The transmission peak is intended to be eccentric, and the second can be used to finely grind the processed material to achieve the effect of improving the ' 顾 使用者 使用者 使用者 顾 顾 顾 顾 顾 顾 顾With the Γ :: the equal Γ grinding form 'not only (four) the practicality of the grinding machine' to shorten the processing time. [Embodiment] 6 M339612 The characteristics of the present invention can be clearly understood by referring to the detailed description of the drawings and the embodiments. As shown in the second to fourth figures, the transmission mechanism of the present invention includes: a counterweight eccentric shaft 30, a spindle 4〇, a brake pad 5〇 < a pressure plate 60 and a grinding disc 20; wherein: The counterweight eccentric shaft 30 is a transmission shaft of the main motor ι〇 (not shown). In implementation, the horse 10 system can be operated by electric power or dust gas, thereby driving the counterweight eccentric shaft 30 to rotate at a predetermined rotation speed. The counterweight eccentric shaft 3〇 includes a weight 31. The mandrel 40 is relatively disposed below the counterweight eccentric shaft 3 , for the grinding disc 20. And a brake pad 50 is disposed on the mandrel 40 and disposed between the counterweight eccentric shaft 3〇 and the grinding disc 20, and the brake pad 5〇 is coupled with the weight 31 and has a gap 71′ and the matching The area of the weight 31 is greater than or equal to the area of the brake pad 5〇. The Lili board 60 is disposed on the mandrel 4' and is disposed between the brake pad 5 and the honing disc 20. The pressure plate 6 is provided with a plurality of fins 61, and the web 50 and the pressure plate 60 are second. a gap 72, and the mandrel sleeve is provided with two spacers 80, and the two spacers 80 are respectively disposed between the brake pad 5 and the pressure plate 6G, and between the pressure plate (10) and the grinding disk 2 (), and the second plate 60 Different abrasive forms can be formed with the brake pad 50 relative to the counterweight eccentric shaft 3 =1. Please use the same as shown in the fifth and sixth figures. After the whole motor is started by pressing the trigger motor, the motor's transmission shaft will transmit power = 7 M339612 = counterweight eccentric shaft 3G, and The brake pad 5Q, the pressure plate 6g and the grinding disc 20 are simultaneously rotated. When the counterweight is eccentrically rotated, the flaps 61p of the pressure plate 60 will be turned upwards, and Pushing the brake pad 5 (f) in close contact with the bottom surface of the weight 31 of the counterweight eccentric shaft 30 (for example, at this time, the grinding disc 20 and the counterweight eccentric shaft 3 〇 concentric high speed, the grinder can add 1 9G Grinding form of rough grinding; in the concrete =, the surface of the shai pressure plate 60 is 兮 $ right#; also contact effect. Surface praise " also has a right dry bump 62 to increase friction at this time due to processing The material material change 'must be changed to the fine grinding method'. At this time, the user only needs to press the grinding disc 20 toward the workpiece 90 side, so that the grinding disc 20 and the garb (10) are in contact with the frictional pressure of the employee. At this time, the pressure plate 6〇 and the brake pad 5G are returned to the position where the bottom surface of the weight 31 which is not eccentric = the weight is closed, as shown in the fourth figure and the The figure is not 'the grinding disc 20, that is, the transmission of the counterweight eccentric shaft 3G is rotated by any rail eccentricity', and the grinding can be performed by the fine grinding of the 9G. The effect of changing the grinding form is achieved. Yu Xia grinder has the following advantages: ... The single grinder can have different grinding forms such as rough grinding and grinding, which not only increases the practicability of the grinder, but also shortens the processing time. The different grinding forms formed by this creation do not require any switching to save the user's troublesome movements. 3. The user can operate M339612 (pressure on the workpiece) by simple force application as required. The coarse or fine grinding form of the grinding machine can be changed.
