Description

Polishing equipment for spheres

The present invention relates to a polishing equipment for spheres.

In many spherical products, in order to obtain conditions such as smooth surface and true roundness of the sphere, it is usually necessary to polish and polish the surface of the spherical product. In order to effectively stabilize the spherical product and perform complete grinding and polishing on the spherical surface in all directions, the conventional grinding and polishing device includes at least three grinding units and at least one toggle unit, the at least three grinding units are respectively located at one of the corners of the spherical product For the different areas of the spherical surface to be ground separately, the at least one toggle unit is used to cause the spherical product to deflect, so that the at least three grinding units can indeed grind to all areas of the spherical surface. TW201436935 reveals this kind of thing.

However, such conventional grinding and polishing devices have extremely complex structures and high manufacturing costs. In addition, the coordination between multiple grinding units and toggle units is not easy to precisely coordinate and control, and errors are likely to occur, resulting in polishing efficiency, polishing stability, and Poor polishing and other problems, and spherical products cannot obtain better roundness.

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

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

In order to achieve the above object, the present invention provides a polishing device for a ball, including: a base, including a cylinder for supporting a ball to be polished; a fluid pressurizing unit connected to the cylinder The inside is used for supplying fluid into the cylinder to push and support the sphere; a grinding piece is arranged in a relatively movable configuration with the cylinder for grinding the surface of the sphere and at the same time friction driving the sphere to rotate.

The following examples are only used to illustrate the possible implementation aspects of the present invention, but they are not intended to limit the scope of protection of the present invention, and are described 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.

The base 10 includes a cylinder 11 for supporting a ball 60 to be polished; the fluid pressurizing unit 20 is connected to the inside of the cylinder 11 for supplying fluid (gas or liquid) into the cylinder The ball 60 is pushed inside the member 11 to reduce the frictional resistance of the ball 60 or the ball 60 can be directly suspended relative to the cylinder member 11; the grinding member 30 and the cylinder member 11 are in a relatively movable configuration for grinding the The surface of the sphere 60 and friction drive the sphere 60 to rotate at the same time. As a result, the polishing device 1 for the ball has a simple structure and low cost, and uses fluid to uniformly and omnidirectionally push the ball 60. During the polishing process, the contact between the abrasive 30 and the ball 60 is extremely stable, so The sphere 60 has excellent polishing efficiency, polishing stability, and polishing effect (such as smoothness, roundness, etc.).

The base 10 further includes a moving rail 12 and a supporting member 13 movably disposed on the moving rail 12, the cylindrical member 11 is disposed on the supporting member 13, preferably, the cylindrical member 11 and the supporting member 13 At least one of the members 13 has a better shock-absorbing effect (the one with lower rigidity), which helps polishing stability. The base 10 further includes a driving device 14 connected to the supporting member 13, and the driving device 14 is used to drive the supporting member 13 to move relative to the grinding member 30, so that the ball 60 can quickly move to the position to be ground, or after the grinding is completed Return quickly. The cylindrical member 11 is preferably installed on the carrier 13 in a replaceable manner, and the cylindrical 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. 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, relatively upward, the cylindrical member 11 can move back and forth (the first direction D1), and the grinding 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 30 can be constructed to swing relative to the first direction D1 (along the third direction D3). By changing the contact position and angle between the abrasive 30 and the ball 60, different polishing efficiency can be obtained. , Polishing stability and polishing smoothness.

In this embodiment, the cylinder 11 has a single opening 111 for receiving a part of the sphere 60. When the fluid flows into the cylinder 11, it has a better pushing effect and is easy to control. The extent to which the fluid pushes and supports the ball 60 (the size of contact friction, or suspension). One end cover of the cylinder 11 is provided with a multi-channel layer 40 for holding the sphere 60. The multi-channel layer 40 can be a fiber cloth layer, a woven or non-woven structure, and an integral or non-integral molded component. The multi-channel layer 40 allows the fluid to pass through and makes the air flow more stable. The multi-channel layer 40 further homogenizes the distribution of the supporting force of the fluid on the sphere 60 and optimizes and stabilizes the grinding conditions. In addition, the multi-channel layer 40 can also effectively scrape off the dust generated by the grinding during the polishing and rotating process of the ball 60, which can improve the smoothness of the polished surface. The multi-channel layer 40 is positioned and installed on the cylindrical member 11 through a bundle member 50. The bundle member 50 is preferably a ring member with an adjustable circumference, which is convenient for quick installation and replacement of the multi-channel layer 40.

The fluid pressurizing 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 the configuration requirements of different working environments and has a relatively high Good applicability and adjustability. The fluid is pressurized by the pump 21 to pass into the inside of the cylinder 11, and the pressurized fluid pushes up the ball 60, reducing the frictional resistance of the ball 60, and facilitates, effective and smooth grinding operations .

The grinding member 30 includes a grinding surface 31. In the direction in which the grinding surface 31 faces the cylindrical member 11, the center line C1 of the grinding surface 31 and the center line C2 of the cylindrical member 11 are misaligned with each other, thereby, during the grinding process In this case, the sphere 60 is automatically driven by the grinding member 30 to perform a left or right angular deflection, so that it can automatically grind to all azimuth areas on 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.
