Grinding device

The present invention relates to a machining apparatus, and more particularly to a grinding apparatus that can be used for a cylinder.

At present, the grinding technology commonly used for cylinders is usually manually grinded by the operator using the sandpaper to the rotating joint portion of the cylinder. Since the manual control is used, the rotating joint portion of the cylinder is often not uniformly ground, or In the case where the surface roughness is still too high, the above conditions often cause the cylinder (such as the rotor axis) to be applied or assembled to a specific object (such as a motor), and the rotating joint portion is in close contact with the peripheral components due to uneven roughness. In addition, it will generate noisy noise, and even shorten the service life of the object to be applied, which will cause great trouble to the user in terms of usability. In combination with the above problems, the conventional grinding technique still has inconvenience and needs to be improved.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a polishing apparatus which can provide a relatively uniform surface roughness of the polished cylinder, increase the grinding quality, and save labor costs.

In order to achieve the above object, the present invention provides a polishing apparatus for grinding a cylinder having a rotating shaft, the grinding apparatus comprising a fixing component, a displacement component and an grinding component; the fixing component has a positioning a unit, the cylindrical system is rotatably disposed on the positioning unit with the rotating shaft as an axis; the displacement assembly has a bearing portion, and the displacement assembly is disposed on the fixing component in a manner movable along an axial direction of the rotating shaft a position of the bearing portion corresponding to the cylinder; the grinding assembly is disposed at the bearing portion and located at a position corresponding to a surface of the rotating shaft; thereby, when the cylindrical body is rotated about the rotating shaft The grinding assembly can grind the surface of the rotating shaft in a circumferential direction, and when the displacement assembly moves along the axial direction of the rotating shaft, the grinding assembly also moves along the axial direction of the rotating shaft of the cylinder and is linear Grinding the surface of the rotating shaft to achieve uniform polishing of the surface of the rotating shaft.

The detailed construction and features of the present invention will be described in the following detailed description of the embodiments. However, it should be understood by those of ordinary skill in the art that the present invention is not limited by the scope of the invention.

As shown in FIG. 1 to FIG. 5, the grinding apparatus 10 provided by the present invention is mainly used for grinding a cylinder 20. The cylinder 20 provided in the preferred embodiment is exemplified by a motor rotor, and the cylinder 20 has A rotating shaft 22 includes a fixing assembly 30, a displacement assembly 40 and two grinding assemblies 50.

The fixing component 30 includes a bearing surface 32, a positioning unit 34, a driving unit 36 and an urging unit 38.

The cylinder 343 and a positioning space 344, one end of the two cylinders 343 is vertically disposed on the bearing surface 32, and the two fixed shafts 342 are respectively disposed at the other ends of the two cylinders 343. The axes of the two fixed shafts 342 are located on the same axis, and the positioning space is Between the two fixed shafts 342, the cylindrical body 20 is rotatably disposed on the positioning space 344 with the rotating shaft 22 as an axis, and the two fixed shafts 342 respectively abut against the two ends of the rotating shaft 22, thereby making the cylindrical body 20 rotate. 22 is the axis rotation.

The driving unit 36 includes a first power source 362 and a driving member 364. The driving member 364 can be between a first position P1 (as shown in FIG. 2) and a second position P2 (as shown in FIG. 5). For deflection, the first power source 362 can be a motor or the like to provide power to drive the drive member 364 to act. The drive member 364 can be a belt set or the like. When the driving member 364 is located at the first position P1, the first power source 362 drives the driving member 364 to actuate. Since the driving member 364 is pressed against the cylinder 20, the cylinder 20 can also be driven to rotate the shaft 22 as an axis. The core rotates, and when the driving member 364 is at the second position P2, the driving member 364 is separated from the cylinder 20, and the cylinder 20 can be stopped. The urging unit 38 includes a second power source 382 and a cam 384 that provides power to rotate the cam 384.

The displacement assembly 40 is disposed on the bearing surface 32. The displacement assembly 40 includes a bearing portion 42, a rail unit 44, and a card slot 48. The displacement assembly 40 is movably disposed above the bearing surface 32 by the rail unit 44. 42 positions of the corresponding cylindrical body 20, the bearing portion 42 has two symmetrical grooves 422, the two ends of the rotating shaft 22 of the cylindrical body 20 can be respectively placed in the two grooves 422, the bearing portion 42 adjacent to the two grooves 422 The position of the other is separately provided with a clamping slot 46. The card slot 48 is disposed on the side of the displacement assembly 40, and the cam 384 and the card slot 48 are pressed against each other. When the second power source 382 drives the cam 384 to rotate, the cam 384 is pressed against the card slot 48, so the cam 384 also drives the displacement. The assembly 40 reciprocates in a straight line at the load bearing surface 32.

The grinding assembly 50 is a sandpaper, an abrasive cloth or the like which has the same abrasive action. The grinding assembly 50 can be in the form of a sheet or a self-retracting winding. The grinding assembly 50 is respectively placed on each of the clamping slots 46 for grinding. The components 50 are respectively located at the two end surfaces of the rotating shaft 22 of the cylinder 20. When the two ends of the rotating shaft 22 of the cylinder 20 are respectively disposed on the two grooves 422, the surfaces of the rotating shafts 22 of the cylindrical body 20 can respectively abut. The assembly 50 is milled.

In combination with the above technical features, please refer to FIG. 1 and FIG. 2, and further, the cylinder 20 is disposed on the carrying portion 42, and the surfaces of the rotating shafts 22 of the cylindrical body 20 are respectively in contact with the grinding assembly 50, and The two fixed shafts 342 abut against the two ends of the rotating shaft 22, and when the driving member 364 is at the first position P1, the driving member 364 can press against the cylindrical body 20 to make the two ends of the rotating shaft 22 more closely abut against the grinding assembly. 50, please refer to FIG. 3 and FIG. 4 again. When the first power source 362 drives the driving member 364, the driving member 364 also drives the cylinder 20 to rotate the cylinder 20 about the rotating shaft 22, and the grinding assembly 50 The surface of both ends of the rotating shaft 22 can be ground in the circumferential direction, and the second power source 382 simultaneously provides a power to rotate the cam 384, since the two ends of the rotating shaft 22 of the cylinder 20 are respectively abutted by the two fixed shafts 342, the cam 384 will drive the card slot 48 to reciprocate the entire bearing portion 42 in the axial direction of the parallel rotating shaft 22, so that the grinding assembly 50 will reciprocate along the rotating shaft 22 of the cylinder 20 and grind the two ends of the rotating shaft 22 in a linear direction. Surface, which produces the effect of reciprocating grinding.

It is worth mentioning that, due to the cylindrical grinding technology of the prior art, the operator usually uses sandpaper to manually grind the axis of the cylinder, and because of the manual control, it is easy to cause uneven grinding, which leads to the When a cylinder (such as a rotor shaft) is applied to an electric appliance (such as a motor), the cylinder and its peripheral components are poorly sealed to generate noisy noise, and may reduce the service life of the electrical appliance. The grinding device 10 provided by the present invention cooperates with the positioning unit 34, the driving unit 36 and the pressing unit 38 by the displacement assembly 40, and simultaneously reciprocates the rotating shaft 22 of the cylinder 20 in a circular and linear direction, which not only saves manpower The cost, in turn, allows the surface of the rotating shaft 22 to be ground to have a fine and uniform surface roughness.
