[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, a clamping assembly for processing the frame of an LED display screen includes a finishing platform 1, on which at least two sliders 2 are slidably arranged, and the movement directions of the two sliders 2 are parallel or perpendicular to each other, and a push-pull cylinder 3 connected to the slider 2 is arranged on the finishing platform 1;

[0028] Clamping plates 4 are provided at both ends of the slider 2 in the sliding direction, and a clamping area for the frame to be placed is formed between the clamping plates 4 at the top of the slider 2;

[0029] The clamping plates 4 at both ends are perpendicular to each other. A rotating shaft 5 connected to the clamping plates 4 at both ends is rotatably provided on the slider 2 . A small servo motor 6 connected to the rotating shaft 5 is provided on the slider 2 .

[0030] Specifically, the frame is aligned with the clamping area of ​​the plurality of sliders 2, and the frame is placed on the plurality of sliders 2. When the outer side of the frame needs to be finely processed, the servo motor drives the rotating shaft 5 to rotate, so that the clamping plate 4 located on the inner side of the frame rotates from horizontal to vertical. At this time, the plane where the top of the clamping plate 4 is located is located above the plane where the top of the slider 2 is located, that is, the top of the clamping plate 4 is located on the inner side of the frame. Then the push-pull cylinder 3 pulls the slider 2 to move outward, so that the plurality of clamping plates 4 clamp the frame from the inner side of the frame, thereby avoiding the clamping assembly from hindering the fine processing of the frame. Conversely, when the inner side of the frame needs to be finely processed, the servo motor drives the rotating shaft 5 to rotate 90° in the opposite direction, so that the top of the clamping plate 4 is located on the outer side of the frame, and then the push-pull cylinder 3 pushes the slider 2 to move, so that the plurality of clamping plates 4 clamp the frame from the outer side of the frame, so as to facilitate fine processing of the inner side of the frame.

[0031] The utility model controls the raising and lowering of the clamping plates 4 at both ends by means of a servo motor arranged on the slider 2, so that the slider 2 can clamp the frame from the inner side and the outer side of the frame, thereby meeting the need to clamp the frame when the inner side and the outer side of the frame are successively finely processed.

[0032] like Figure 1 and Figure 2 As shown, at least two slide grooves 7 are provided on the finishing platform 1, the slider 2 is embedded and slidably arranged in the corresponding slide groove 7, and the push-pull cylinder 3 is fixedly arranged in the slide groove 7. On the one hand, the slide groove 7 is used to limit the guide of the slider 2, and on the other hand, it is good for aesthetics.

[0033] like Figure 3 As shown, stop grooves 8 are provided on the groove walls on both sides of the slide groove 7, and stop blocks 9 slidably plugged with the stop grooves 8 are provided on both sides of the slider 2. Through the cooperation of the stop blocks 9 and the stop grooves 8, the finishing platform 1 limits the slider 2 in the vertical direction to prevent the slider 2 from jumping and affecting the finishing effect of the frame.

[0034] like Figure 2 As shown, the finishing platform 1 includes a table 101 provided with a slide groove 7 and a stop groove 8, and a square frame 102 sleeved outside the table 101, a plug 103 is provided in the slide groove 7, and the push-pull cylinder 3 is connected to the square frame 102 through the plug 103, so as to facilitate the disassembly and assembly of the slider 2. The role of the square frame 102 and the plug 103 is to limit the slider 2 and cover the slide groove 7 and the stop groove 8 on the side to facilitate the appearance.

[0035] In addition, the connection method between the plug 103 and the push-pull cylinder 3 and the frame 102 can be welding, bonding, fastener connection, etc., and it is only necessary to fix the push-pull cylinder 3, which will not be described in detail here.

[0036] like Figure 4 As shown, both ends of the slider 2 are provided with right-angle grooves 10, and the right-angle grooves 10 at least penetrate the top of the slider 2, and the clamping plate 4 is rotatably arranged in the corresponding right-angle grooves 10, so as to realize the embedded installation of the clamping plate 4 on the slider 2, which is good for appearance. Correspondingly, the slider 2 is provided with an axis hole 11 connecting the right-angle grooves 10 at both ends, and the rotating shaft 5 is rotatably arranged in the axis hole 11.

[0037] like Figure 3 As shown, both ends of the slider 2 are provided with limit plates 12 for axially limiting the clamp 4. The limit plates 12 are detachably arranged on the slider 2 by a plurality of screws to facilitate the disassembly and assembly of the rotating shaft 5 and the clamp 4, and can provide axial support for the clamp 4, which is beneficial to avoid bending and deformation of the rotating shaft 5 caused by long-term clamping of the clamp 4.

[0038] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
