Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 2, a novel polishing machine 10 includes: housing 11, brushless motor, switch 23, motor shaft 24, output shaft 13, transmission 14, mounting plate 15 and polishing plate 16.
The housing 11 is formed with a grip portion 12. When a worker polishes a surface to be polished by using the novel polishing machine 10, the novel polishing machine 10 is lifted by the handheld holding portion 12, and thus polishing operation is performed.
The brushless motor is disposed in the housing 11. The brushless motor provides power for the novel polishing machine 10 to achieve polishing action.
The switch 23 is disposed on the outer surface of the housing 11 for a user to operate to turn on or off the brushless motor, so as to turn on the novel polishing machine 10 to perform a polishing action and turn off the novel polishing machine 10 to finish the polishing action.
The motor shaft 24 is driven by a brushless motor. Specifically, the brushless motor realizes power transmission through the motor shaft 24 to realize polishing action.
The output shaft 13 is rotatably supported on the housing 11. The brushless motor drives the output shaft 13 through the motor shaft 24.
The transmission 14 is disposed within the housing 11 and between the motor shaft 24 and the output shaft 13 to connect the motor shaft 24 and the output shaft 13. The transmission device 14 can change the rotating speed of the motor shaft 24, so that the rotating speed transmitted to the output shaft 13 is moderate, and the polishing requirement of the novel polishing machine 10 is met.
The mounting plate 15 is circular and is fixedly connected to one end of the output shaft 13. A polishing pad 16 for contacting a surface to be polished to perform polishing is attached to the mounting plate 15. The output shaft 13 drives the mounting plate 15 to rotate so as to drive the polishing plate 16 to rotate at a high speed for polishing. The sanding sheet 16 in this embodiment is circular.
As a further embodiment of the above scheme, the novel polishing machine 10 further comprises: a shield 17 and a sponge member 18. A shield 17 is connected to the housing 11 and surrounds the mounting plate 15. The sponge member 18 is connected to the shield 17. When the polishing sheet 16 on the mounting plate 15 performs a polishing action, the protective cover 17 confines dust generated by polishing in the protective cover 17. After the polishing of the polishing sheet 16, the sponge member 18 is pressed against the surface to be polished by the gravity of the novel polishing machine 10 and the pressure applied by the worker, and the dust is swept into the protective cover 17 while moving. And because the sponge piece 18 is made of soft material, the surface to be polished can be secondarily polished during moving, so that slight scratches of the polished polishing piece 16 can be repaired. By the arrangement, after the novel polishing machine 10 performs polishing action, the polished surface is clear and visible, and a worker can immediately judge whether the polishing is needed to be continued, so that the working efficiency is improved.
As a preferred embodiment, the protective cover 17 is provided in a cylindrical shape. One end of the shield 17 is open and the other end is provided with a circular hole 171. The circular hole 171 is penetrated by the output shaft 13 to connect with the mounting plate 15.
Specifically, the shield 17 is removably attached to the housing 11 to facilitate removal of the shield 17 for cleaning. The sponge member 18 is cylindrical with both ends open. One end of the sponge member 18 is connected to the open end of the hood 17. While the other end of the sponge member 18 contacts the surface to be polished.
In a specific embodiment, the plane of the end of the sponge member 18 remote from the housing 11 is spaced further from the mounting plate 15 than the plane of the end of the polishing sheet 16 remote from the housing 11. The sponge member 18 is made of elastic material, so that when the novel polishing machine 10 is pressed to enable the polishing sheet 16 to contact with the surface to be polished for polishing, the sponge member 18 deforms under the action of pressure to compress the surface to be polished, and therefore the friction force between the sponge member 18 and the surface to be polished is increased, and cleaning and secondary polishing are achieved.
As a further aspect of the above aspect, a length of a portion of the sponge member 18, which is distal from the case 11 and exceeds the polishing blade 16, is 3mm or more and 8mm or less. Such a data range setting can not only ensure that the friction force between the sponge member 18 and the surface to be polished is sufficiently large, but also avoid the phenomenon that the polishing sheet 16 cannot contact the surface to be polished for polishing due to the thicker sponge member 18. In this embodiment, the portion of the sponge member 18 remote from the housing 11 beyond the sanding sheet 16 is 5mm in length.
As a further alternative, the ratio of the length of the portion of the end of the sponge member 18 remote from the housing 11 beyond the polishing pad 16 to the thickness of the sponge member 18 in the direction of the output shaft 13 ranges from 0.15 or more to 0.3 or less. In the present aspect, the ratio of the length of the portion of the end of the sponge member 18 remote from the housing 11 beyond the polishing pad 16 to the thickness of the sponge member 18 in the direction of the output shaft 13 is 0.2.
As a specific embodiment, the ratio of the area of the end surface of the sponge member 18 at the end away from the housing 11 to the area of the polishing sheet 16 ranges from 0.5 or more to 1 or less. This arrangement makes the area of the polishing sheet 16 sufficiently large, thereby ensuring the polishing efficiency. Meanwhile, the contact area between the sponge piece 18 and the surface to be polished is properly large, and the cleaning force of the surface to be polished is ensured. In this embodiment, the ratio of the area of the end surface of the sponge member 18 remote from the housing 11 to the area of the polishing sheet 16 is 0.8.
As a preferred embodiment, the novel polishing machine 10 further comprises a connecting ring 19. The connection ring 19 has one end fixedly connected to the sponge member 18 and the other end connected to the shield 17. In particular, the sponge member 18 is connected to the protective cover 17 by a connection ring 19.
Further, the novel polishing machine 10 further includes a magnetic ring 20. The end of the shield 17 remote from the housing 11 is provided with an annular groove 172 which receives the magnetic ring 20. The shield 17 and the connection ring 19 are made of iron. At least a portion of the connecting ring 19 is located within the annular groove 172.
Specifically, the magnet ring 20 is positioned within the annular groove 172. Since the shield 17 and the connection ring 19 are made of iron, the magnetic ring 20 is firmly attracted in the annular groove 172, and the portion of the connection ring 19 located in the annular groove 172 is tightly attracted to the magnetic ring 20. This achieves a detachable mounting of the attachment ring 19 to the protective hood 17, facilitating the detachment of the attachment ring 19 and the sponge member 18 for replacing or cleaning the sponge member 18.
In a preferred embodiment, a gap 21 is provided between the sponge member 18 and the sanding sheet 16. The hood 17 is provided with a suction portion 173. The suction portion 173 is provided with a suction hole 174 communicating the inside and the outside of the shield cap 17. The new polisher 10 also includes a vacuum pump and connecting hose 22. The connection hose 22 is connected at one end to the suction hole 174 and at the other end to the suction end of the vacuum pump. The vacuum pump draws out the dust particles in the protective hood 17 through the connecting hose 22. The dust particles are sucked into the connecting hose 22 through the gap 21 into the suction opening 174 by the vacuum pump.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
