Polishing equipment for spheres

The present invention relates to a polishing apparatus for spheres.

On many spherical products, in order to obtain a smooth surface and true roundness of the sphere, it is usually necessary to grind and polish the surface of the spherical product. In order to effectively stabilize the spherical product and perform complete grinding and polishing of the spherical surface, the conventional grinding and polishing device includes at least three grinding units and at least one toggle unit, and the at least three grinding units are respectively located at one of the corners of the spherical product , for grinding different areas of the spherical surface, the at least one toggle unit is used to deflect the spherical product, so that the at least three grinding units can actually grind all areas of the spherical surface, such as that disclosed in TW201436935.

However, the structure of such a conventional grinding and polishing device is extremely complex, and the manufacturing cost is high. In addition, the coordination between the plurality of grinding units and the toggle unit is not easy to be precisely controlled, and errors are easily generated, resulting in poor polishing efficiency, polishing stability and poor performance. Problems such as poor polishing and smoothness, and spherical products can not obtain better roundness.

Therefore, it is necessary to provide a novel and progressive polishing apparatus for spheres to solve the above problems.

The main purpose of the present invention is to provide a polishing apparatus for spheres, which has a simple structure and has good polishing efficiency, polishing stability and polishing effect.

In order to achieve the above object, the present invention provides a polishing equipment for spheres, comprising: a base, including a cylindrical member for supporting a sphere to be polished; a fluid pressurizing unit connected to the cylinder member Inside, the fluid is fed into the cylinder to push and support the sphere; a grinding member, which is relatively movable with the cylinder, grinds the surface of the sphere and drives the sphere to rotate at the same time.

The following examples are only used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

Please refer to FIGS. 1 to 6 , which show a preferred embodiment of the present invention. The polishing apparatus 1 for spheres of the present invention includes a base 10 , a fluid pressurizing unit 20 and a grinding member 30 .

Therefore, the polishing apparatus 1 for spheres has a simple structure and low cost, and utilizes fluid to push the spheres 60 uniformly and omnidirectionally. The polishing efficiency, polishing stability and polishing effect (eg smoothness, roundness, etc.) of the sphere 60 are excellent.

The base 10 further includes a moving rail 12 and a bearing member 13 movably disposed on the moving rail 12 , the cylindrical member 11 is disposed on the bearing member 13 , preferably, the cylindrical member 11 and the bearing member 13 At least one of the pieces 13 has better shock absorption effect (the one with lower rigidity), which is helpful for grinding stability. The base 10 further includes a driving device 14 connected to the carrier 13 . The driving device 14 drives the carrier 13 to move relative to the grinding piece 30 , so that the ball 60 can be quickly moved to the position to be ground, or after grinding is completed. Back quickly. The cylinder member 11 is preferably installed on the carrier member 13 replaceably, and a cylinder member 11 of an appropriate size can be selected according to different sizes of spheres. In this embodiment, the driving device 14 is a telescopic cylinder device (air pressure, oil pressure, etc.), but it can also be driven by a transmission mechanism such as a screw, a chain or a belt.

Preferably, the cylindrical member 11 can move along a first direction D1, and the grinding member 30 can move along a second direction D2, and the second direction D2 is not parallel to the first direction D1. In this embodiment, The second direction D2 is perpendicular to the first direction D1. For example, the cylindrical member 11 can move forward and backward (the first direction D1), and the abrasive member 30 can move left and right (the second direction D2) or/and up and down. According to the movement, the optimal relative grinding position and angle can be adjusted according to the size of the sphere 60 . Preferably, the abrasive element 30 can be configured to swing relative to the first direction D1 (along the third direction D3 ). By changing the contact position and angle between the abrasive element 30 and the ball 60 , different polishing efficiencies can be obtained. , polishing stability and polishing smoothness.

In this embodiment, the barrel 11 has a single opening 111 for receiving a part of the sphere 60 . When the fluid passes into the barrel 11 , it has a better pushing effect and is easy to control. The degree of propelling (contact friction, or suspension) of the fluid to the sphere 60 . One end of the cylindrical member 11 is replaceably provided with a multi-channel layer 40 for holding the ball 60 . The multi-channel layer 40 allows the fluid to pass through, making the air flow more stable. The multi-channel layer 40 further uniformizes the distribution of the support force of the fluid on the sphere 60, thereby optimizing and stabilizing the grinding conditions. In addition, the multi-channel layer 40 can also effectively scrape off the dust generated by grinding during the polishing and rotation of the sphere 60 , thereby improving the smoothness of the polished surface. The multi-channel layer 40 is positioned and mounted on the cylindrical member 11 through a bundle 50 . The bundle 50 is preferably a ring member with an adjustable circumference, which can facilitate and quickly install and replace the multi-channel layer 40 .

The fluid boosting unit 20 includes a pump 21 and a pipe 22 connecting the pump 21 and the inside of the cylinder 11 . The pipe 22 is flexible, so that it can be adapted to different working environments. Good applicability and adjustment. The fluid is pressurized by the pump 21 and then passes into the interior of the cylinder 11, and the pressurized fluid pushes the sphere 60 upwards, reducing the frictional resistance of the sphere 60 and facilitating the efficient and smooth grinding operation .

The grinding member 30 includes a grinding surface 31. In the direction in which the grinding surface 31 faces the cylindrical member 11, the centerline C1 of the grinding surface 31 and the centerline C2 of the cylindrical member 11 are displaced from each other. In the middle, the sphere 60 is automatically driven by the grinding member 30 to deflect left or right, so that it can automatically grind to all azimuth areas of the surface of the sphere 60 . Preferably, the contact position between the grinding surface 31 and the sphere 60 is located in the hemispherical area above the sphere 60 , so that the degree of grinding, the stability of the sphere 60 and the sphere 60 can be reliably rotated.
