DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0018] For example, Figures 1 to 5As shown, a ceramic rod double-sided grinding jig comprises an upper grinding disc 100 and a lower grinding disc 101, the upper grinding disc 100 and the lower grinding disc 101 are arranged in parallel, the lower grinding disc 101 is provided with an inner ring gear 102 on the outer periphery, the lower grinding disc 101 is provided with a central shaft 104 at the bottom center position, the central shaft 104 is sleeved with a sun gear 105 on the shaft body, the lower grinding disc 101 is provided with a grinding mechanism for uniform grinding of the ceramic rod body 103 on the outer periphery of the sun gear 105, the upper grinding disc 100 is provided with a through hole for the central shaft 104 to penetrate, the upper grinding disc 100 is sleeved on the shaft body of the central shaft 104 by the through hole, and is arranged above the lower grinding disc 101.

[0019] During processing, the ceramic rod body 103 to be processed is placed in the grinding mechanism, under the action of the processing load, the parallel and flat upper grinding disc 100 and the lower grinding disc 101 press the ceramic rod body 103 to be processed, the upper grinding disc 100 and the lower grinding disc 101 rotate around the central shaft 104, and the ceramic rod body 103 to be processed is ground, which improves the consistency of the ceramic rod body 103, can be mass-produced, and the processing precision is greatly improved, and the ceramic rod shaft product is processed by the double-sided grinding equipment.

[0020] In the embodiment, the grinding mechanism comprises a product jig 200 mounted on the upper surface of the lower grinding disc 101, the outer periphery of the product jig 200 is toothed and connected with the inner ring gear 102, the product jig 200 is provided with a matching hole 204, the eccentric wheel 202 is movably arranged in the matching hole 204, the eccentric wheel 202 is provided with a mounting hole 203, the eccentric wheel 202 is connected with the sun gear 105 by the mounting hole 203, the geometric center of the eccentric wheel 202 is eccentric from the rotation center of the central shaft 104, the geometric center of the product jig 200 coincides with the geometric center of the eccentric wheel 202, a plurality of grooves 201 are arranged on the circumferential surface of the product jig 200, and the ceramic rod body 103 is placed in the groove 201 and contacts with the upper grinding disc 100 and the lower grinding disc 101.

[0021] The central shaft 104 rotates to drive the sun gear 105 to rotate. Since the eccentric wheel 202 is connected with the sun gear 105 in meshing mode, and the geometric center of the eccentric wheel 202 is eccentric to the rotation axis center of the central shaft 104, when the sun gear 105 rotates, the eccentric wheel 202 drives the product fixture 200 and the ceramic rod body 103 thereon to perform planetary motion, that is, the ceramic rod body 103 revolves around the central shaft 104 and rotates around its own geometric center, so that the machining track of the outer circular surface of the ceramic rod body 103 is complicated and uniform. The planetary motion enables the ceramic rod body 103 to uniformly contact the upper grinding disc 100 and the lower grinding disc 101 in the grinding process, thereby achieving double-sided grinding. For different ceramic rod products, the eccentricity, outer diameter and rotation speed of the eccentric wheel 202, the number of teeth of the outer ring of the product fixture 200 and the thickness of the eccentric wheel 202 and the product fixture 200 can be changed to adapt to different products, thereby enhancing the adaptability and flexibility of the fixture.

[0022] In the embodiment, the upper grinding disc 100 is provided with a pore flow channel.

[0023] The aqueous abrasive is transported from the pore flow channel of the upper grinding disc 100 to the contact area between the product and the upper grinding disc 100 and the lower grinding disc 101. Since there is relative motion among the upper grinding disc 100, the lower grinding disc 101, the abrasive and the ceramic rod body 103, the abrasive can remove a small amount of material from the cylindrical surface of the ceramic rod body 103.

[0024] Working process and principle: when the device is used, the ceramic rod body 103 to be processed is placed in the plurality of grooves 201 of the product fixture 200, so that each ceramic rod body 103 is stably and uniformly distributed in the groove. Under the action of the machining load, the parallel and flat upper grinding disc 100 and the lower grinding disc 101 press the ceramic rod body 103 to be processed. The upper grinding disc 100 and the lower grinding disc 101 rotate around the central shaft 104. The central shaft 104 rotates to drive the sun gear 105 to rotate. Since the eccentric wheel 202 is connected with the sun gear 105 in meshing mode, and the geometric center of the eccentric wheel 202 is eccentric to the rotation axis center of the central shaft 104, when the sun gear 105 rotates, the eccentric wheel 202 drives the product fixture 200 and the ceramic rod body 103 thereon to perform planetary motion, that is, the ceramic rod body 103 revolves around the central shaft 104 and rotates around its own geometric center, so that the machining track of the outer circular surface of the ceramic rod body 103 is complicated and uniform. The upper grinding disc 100 and the lower grinding disc 101 are flat and parallel in height, and are used for grinding the ceramic rod body 103 to be processed. In combination with the aqueous abrasive, a small amount of material can be removed from the cylindrical surface of the ceramic rod body to be processed.
