[0031] The present invention provides a grinding carrier for pivotally cooperating with a base body. The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings to make it easier to understand and grasp.

[0032] Grinding carriers for pivot-fit substrates, such as Figure 5 and Figure 6 As shown, the pivot-cooperating base 1 includes a pivot-cooperating portion 11 , an extending portion 12 opposite to the pivot-cooperating portion 11 , and pin-connecting piles 13 located at both sides of the pivot-cooperating portion 11 .

[0033] like Figures 1 to 4 As shown, the grinding carrier includes a grinding carrier 2 , on which a plurality of bearing bases 3 are arranged, and on any bearing base 3 a strip-shaped sink 4 is arranged.

[0034] The strip-shaped groove 4 is provided with a supporting portion 5 for supporting the pin shaft connecting pile 13 , and the bottom of the strip-shaped groove 4 is provided with an inner groove 6 , and the inner groove 6 is provided with a magnetic strip 7 for magnetically adsorbing the pivot shaft and the base 1 .

[0035] Specific implementation process and principle description:

[0036] The support portion 5 is used to limit the position of the pin piercing pile 13 of the pivot mating base 1, and the strip-shaped recessed groove 4 is used to support the main body of the pivot mating base 1 when the pin piercing pile 13 is evaded, so that the pivot mating base 1 is suspended in the strip-shaped recessed groove 4, and the surface to be ground of the pin piercing pile 13 is exposed.

[0037] The magnetic strip 7 can realize the magnetic adsorption limit of the pivot and the base 1. The two are not abutting limit structures. The magnetic strip 7 is mainly used to meet the stability requirements of the pivot and the base 1 during the grinding process to avoid the large shaking of the base during the grinding of the pin shaft through the connecting pile 13 and the impact on the grinding surface. At the same time, the base is not fixed and clamped, which can achieve a certain stress transfer. The finished grinding product is not easy to deform and has a higher precision.

[0038] In a specific embodiment, the pin-through pile 13 includes a first grinding surface 14 and a second grinding surface 15 , and the grinding carrier includes a first grinding carrier 21 for grinding and forming the first grinding surface 14 and a second grinding carrier 22 for forming the second grinding surface 15 .

[0039] That is, by adopting different designs of the support portion 5 , the first grinding surface 14 and the second grinding surface 15 of the pin shaft penetration pile 13 can be ground separately.

[0040] Specifically, Figure 1 and Figure 2 As shown, the pin-through pile 13 includes a supporting surface 16 disposed opposite to the first grinding surface 14 .

[0041] The supporting portion 5 of the first grinding carrier 21 includes a plurality of extension avoidance grooves 211 spaced apart along the direction of the strip-shaped groove 4. The extension portion 12 of the pivotally matched base 1 passes through the extension avoidance groove 211, and the supporting surface 16 is supported on the side wall of the strip-shaped groove of the first grinding carrier 21. The extension portion 12 is magnetically attracted to the magnetic strip 7 in the first grinding carrier 21.

[0042] Specific implementation instructions:

[0043] The pivot mating base 1 is inserted into the extension avoidance groove 211, and the support surface 16 is in contact with the top surface of the side wall of the strip-shaped sinking groove 4, and the magnetic strip 7 produces vertical magnetic adsorption on the pivot mating base 1, so that the limiting of the pin shaft connecting pile 13 is stable and reliable.

[0044] During the grinding process, when the first grinding surface 14 is subjected to the grinding force and stress is generated inside, the stress is transferred to the extending portion 12 so that the stress is eliminated.

[0045] In a specific embodiment, Figure 3 and Figure 4 As shown, the second grinding surface needs to be processed based on the first grinding surface, and the pin-through pile 13 includes a supporting surface 17 arranged opposite to the second grinding surface 15 .

[0046] The supporting portion 5 of the second grinding carrier 22 includes a support 221 disposed on both side walls of the strip-shaped sinking groove 4. The support 221 is a sinking body structure that can limit the pin shaft connecting pile 13 of the pivot-matching base 1 on both sides.

[0047] The supporting surface 17 of the pivot-matching base 1 is limitedly supported on the support platform 221 , and the pivot-matching portion 11 of the pivot-matching base 1 is magnetically attracted to the magnetic strip 7 of the second grinding carrier.

[0048] Similar to the principle of the first grinding carrier, the magnetic strip 7 is used to achieve stable adsorption of the substrate, and the substrate is not fixedly limited, thereby playing a role in stress elimination.

[0049] To optimize this embodiment, a plurality of pivot-matching substrates 1 are mounted on the second grinding carrier 22 , and the extension portions 12 of adjacent pivot-matching substrates 1 abut against the first grinding surface 14 .

[0050] That is, the entire assembly can be realized through the relative cooperation between the pivot coupling bases 1, and they are related to each other, without the need for independent limiting, thus saving costs.

[0051] It should be noted that the support 221 is provided with a limit pile 222 for limiting the pivot coupling base body along the strip-shaped sinking groove direction. That is, only two side limit piles 222 are needed to realize the overall limit of the pivot coupling base body 1 assembled in an in-line manner.

[0052] In a specific embodiment, a plurality of bearing bases 3 on the grinding carrier 2 are centrally symmetrical structures. Any bearing base is arranged to match or be perpendicular to the radial direction of the grinding carrier.

[0053] Such a design enables the loaded pivot coupling base 1 to be ground more evenly, and the product has a higher degree of uniformity.

[0054] From the above description, it can be found that the grinding carrier used for the pivot-matching substrate of the present invention can realize the targeted support and positioning of the pin shaft through-hole by using the support part, and the magnetic strip can produce non-contact adsorption and positioning of the pivot-matching substrate, thereby eliminating the adverse stress generated during the grinding process, the product is not easy to deform, the grinding surface is flat and reliable, and the product qualification rate is greatly improved. It can meet the grinding support requirements of different grinding surfaces and realize the multi-faceted grinding production of the pivot-matching substrate. The overall design is simple and ingenious, with strong pertinence, and is particularly suitable for the mass production requirements of the pivot-matching substrate.

[0055] The above fully describes the technical solution of the present invention. It should be noted that the specific implementation of the present invention is not limited to the above description. All technical solutions formed by ordinary technicians in the field using equivalent or equivalent transformations in structure, method or function based on the spirit of the present invention fall within the protection scope of the present invention.
