Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.
Example 1
As shown in fig. 1, embodiment 1 provides a sandpaper-replaceable ball sanding head including a body 1, a stem 2, a fixing piece 3, and sandpaper 4. The body 1 is a metal body similar to a semi-cylinder. A connecting handle 2 used for being connected with a grinding device is arranged on the rear side surface of the body 1. The connecting handle 2 is made of metal materials so as to improve the reliability of connection with the grinding equipment. The connecting handle 2 and the body 1 can be selectively welded or screwed. The front side surface of the body 1 is provided with an inwards concave arc surface (not shown in the figure), the arc surface is in a semi-cylindrical shape or a less semi-cylindrical shape, namely, the geometric central angle of the arc surface is less than or equal to 180 degrees. The geometric axis of the arc surface is vertically arranged, namely the width direction of the arc surface is vertically arranged, and the width of the optimized arc surface is equal to the height of the body 1. The left end and the right end of the arc surface are provided with arc chamfers 11, and the radius of the arc chamfers 11 is more than or equal to 2 mm. The upper end and the lower end of the arc surface are respectively detachably fixed with a fixing piece 3 in the shape of an arc, the geometric central angle of the fixing piece 3 is the same as that corresponding to the arc surface, and the outer side surface of the fixing piece 3 is attached to the arc surface. The fixing piece 3 is made of a metal material, preferably an elastic metal material. In an optional scheme, be equipped with the screw hole at the upper and lower both ends of arc surface, it has the round hole 31 with screw hole matched with to open on stationary blade 3, close soon through screw 32 and screw hole and fix stationary blade 3 detachably at the arc surface, every stationary blade 3 all is fixed through two screws 32, and is fixed more firmly. Abrasive paper 4 sets up in the middle part of arc surface, and the upper and lower both ends of abrasive paper 4 compress tightly through stationary blade 3 and fix at the arc surface, and the outside and the arc surface laminating of abrasive paper 4, and about 1-2mm width is reserved to the left and right sides of abrasive paper 4 for laminating covers circular arc chamfer 11. Wherein, the radius of arc surface is the thickness sum of the spheroid radius of waiting to polish and abrasive paper 4, and the width of arc surface is the spheroid diameter of waiting to polish and the width sum of two stationary blades 3, guarantees when polishing, waits to polish spheroid 6 and body 1 relative rotation in-process, spheroid 6 not with stationary blade 3 contact. The width direction of the arc surface and the width direction of the fixing piece 3 are the vertical direction in the figure (the height direction of the main body 1).
When using, unscrew or take off screw 32 earlier, paste abrasive paper 4 and put on the arc surface, both ends are located the gap between two stationary blades 3 and the arc surface about abrasive paper 4, then screw up screw 32, press from both sides connecting handle 2 on grinding device's rotary tool 5 again, as shown in fig. 2, fix the relative position who waits to polish spheroid 6 and the polishing head that this embodiment provided, make spheroid 6 surface and abrasive paper 4 laminating, later process, should make spheroid 6 rotatory an angle after polishing spheroid 6 surface part at every turn, polish the polishing operation again. Another method for using the polishing head provided in this embodiment is to use the polishing head as a tool, as shown in fig. 3, clamp the ball 6 to be polished on a rotary tool 5 of a rotary machine, such as a machine tool, clamp the polishing head of the ball of this embodiment on the machine tool fixture, attach the sand paper 4 to the surface of the ball 6, and rotate the rotary tool 5 to complete the processing and polishing of the ball 6. When the precision requirement of the sphere 6 is not high, the sphere polishing head of the embodiment can be directly held by hand to polish and process the sphere 6, and the sphere is not required to be arranged on a machine tool clamp. The angle between the width direction of the arc surface and the rotating shaft can be adjusted in the polishing process, and the polishing area is the largest when the included angle between the axis of the arc surface of the body 1 and the rotating shaft of the sphere 6 is 0 degrees and is close to half of the surface area of the sphere 6; the minimum grinding area is close to zero when the included angle is 90 degrees, but the scratch to the surface of the sphere 6 caused by the use of a smaller grinding area at the same position of the sphere for a long time is avoided.
According to the sphere polishing head with the replaceable abrasive paper, the abrasive paper 4 is detachably fixed on the arc surface of the body 1 through the fixing piece 3, the sphere 6 is polished by the abrasive paper 4, the abrasive paper 4 with different thicknesses (meshes) can be selected according to the requirements of the smoothness and the roughness of the sphere 6, and the purchase cost and the storage cost of the abrasive paper 4 are lower than those of the polishing head and the cutter in the background technology; when the abrasive paper 4 is replaced, the waste abrasive paper 4 or the abrasive paper 4 with different finish requirements can be replaced only by loosening the fixing sheet 3, pressing the abrasive paper 4 under the fixing sheet 3 and then fastening the fixing sheet 3, so that the use is convenient; the ball body 6 is polished by the sand paper 4 with different thicknesses, so that the surface smoothness and roughness of the ball body 6 are higher, and the polishing effect is good.
In this embodiment, the sandpaper 4 is cut by a user to form a shape, and the length of the sandpaper should just ensure that the outer side of the sandpaper closely fits the arc surface and does not tilt up and the arc chamfers 11 on the two sides, and the width of the sandpaper is not smaller than the minimum distance between the two fixed blocks and not larger than the width of the arc surface so as to prevent the arc surface from being exposed. Optionally, the width of the sand paper 4 is not more than the distance between the threaded holes at the upper end and the lower end, or the position of the corresponding threaded hole on the sand paper 4 is punched in advance, and at the moment, the length of the sand paper 4 can be equal to the width of the arc surface. The width direction of the sandpaper 4 means the up-down direction in the figure. In addition, the sand paper 4 should be made of the same series of products of the same manufacturer, and the consistency of the thickness of the paper base is ensured as much as possible.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
