Technical Field

[0001] The utility model relates to the technical field of flat processing, in particular to a grinding device provided with a positioning structure. Background Art

[0002] In the prior art, as a portable electronic device, a tablet computer has become an indispensable part of people's life and work. At present, the backplane of a tablet computer is usually a metal part, and during production and processing, it needs to be ground by a grinding device.

[0003] When grinding, it involves the positioning and support of the outer shell. Currently, there are two common support methods. One is external clamping and positioning. For example, a grinding device for the outer shell of an industrial tablet computer with the Chinese patent publication number "CN210756996U". Since there is contact between the clamping plate and the outer shell, there are grinding dead corners. The other is to set up a support seat to support the inner side of the tablet computer outer shell to achieve the positioning of the tablet computer outer shell.

[0004] Since the existing support seat is set as a fixed structure, for different models of outer shell products, it is often necessary to replace different support seats, resulting in poor applicability to products. At the same time, the repeated replacement affects the production efficiency of enterprises. Summary of the Utility Model

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figures 1-4 This is an embodiment of the present utility model, which discloses a grinding device provided with a positioning structure. The device includes a machine table 1, on which at least one carrier table 2 and a grinding mechanism 3 are slidably arranged. The grinding mechanism 3 can adopt three-axis moving grinding or five-axis moving grinding, which is a conventional means for those skilled in the art and will not be elaborated here too much;

[0023] A driving component 4 for pulling the carrier table 2 to move below the grinding mechanism 3 is also installed on the machine table 1;

[0024] Among them, a fixing block 5 is further provided on the top of the carrier table 2. The fixing block 5 is used to sleeved the outer shell of the flat panel. On the four sides of the fixing block 5, a resisting frame 6 is movably inserted. A locking member 7 for the resisting frame 6 is also arranged on the top of the fixing block 5. A shell removing component 8 is also arranged on the fixing block 5. That is to say, in the present utility model, through the design of four movably inserted resisting frames 6, it can be adaptively adjusted according to the outer shell sizes of different flat panel products, so as to realize the internal positioning and support of the flat panel outer shell and improve the applicability of the product.

[0025] In some embodiments, in the present utility model, the resisting frame 6 is composed of a plate member and two guide rods connected to the plate member, and the guide rods are inserted into the fixing block 5.

[0026] Furthermore, the locking member 7 is a bolt threadedly connected to the fixing block 5, and the end of the bolt can be abutted against the outer side of the guide rod. That is, when the above-mentioned resisting frame 6 is adjusted to the required position, the user can rotate the above-mentioned bolt to tightly abut it against the guide rod, so as to realize the locking and fixing of the position of the resisting frame 6, so as to realize the firm positioning and support of the flat panel outer shell from the inside.

[0027] In addition, the shell removing component 8 includes a ejector rod 81 vertically inserted into the fixing block 5. The bottom of the ejector rod 81 penetrates to the lower part of the carrier table 2, and a spring 82 is fixedly connected between the ejector rod 81 and the bottom of the carrier table 2;

[0028] Among them, a wedge block 83 for abutting against the ejector rod 81 is also arranged on the top of the machine table 1. When the grinding is completed, the driving component 4 drives the carrier table 2 to reset. During this process, when the ejector rod 81 abuts against the wedge block 83, the ejector rod 81 moves upward, so as to abut the flat panel outer shell upward, so as to realize the technical effect of facilitating material removal and improve the convenience of the user to take the product. Secondly, it should be noted that after the material removal is completed, the driving component 4 should pull the carrier table 2 to move in the reverse direction to reset the ejector rod 81 to avoid interference when placing the product.

[0029] Furthermore, in order to reduce the contact friction between the push rod 81 and the wedge block 83 , in the present invention, a ball 84 is embedded at the bottom of the push rod 81 , and the ball 84 contacts and slides with the upper surface of the wedge block 83 .

[0030] In addition, in the embodiment of the utility model, the carrier 2 and the grinding mechanism 3 are both relatively arranged in pairs, and the driving component 4 includes a motor 41 installed under the machine 1, and the shaft end of the motor 41 passes through the machine 1 and is fixedly connected to a rotating plate 42, wherein the end of the rotating plate 42 is transmitted to the carrier 2 through a connecting rod 43.

[0031] That is to say, the motor 41 drives the rotating plate 42 to rotate. When the rotating plate 42 rotates, the two connecting rods 43 pull the two carriers 2 to achieve synchronous movement, and then the two grinding mechanisms 3 perform synchronous grinding, thereby achieving the effect of two-station processing and effectively improving the processing efficiency of the product.

[0032] In summary, the utility model adopts four adjustable abutment frames 6, which can be adaptively adjusted in position according to the size of the flat-panel shell to be processed. This not only avoids the problem of grinding the four corners due to external clamping, but also can perform internal positioning and support for products of different models, thereby improving the positioning applicability of the products. At the same time, a shelling component 8 is also provided on the fixed block 5, which can automatically push the flat-panel shell upwards when the processing is completed, thereby further improving the processing efficiency.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
