[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figure 1-3As shown in the figure, an embodiment of the present invention provides an engineering rivet removal device, including a frame 1, a handle 2 mounted on the frame 1, limit holes 3 on both sides of the inner cavity of the frame 1, limit blocks 4 slidably connected in both limit holes 3, a connecting plate 5 mounted between the two limit blocks 4, grooves 6 on both sides of one end of the connecting plate 5, a clamping component 7 on the connecting plate 5, and a removal component 8 on the frame 1; the clamping component 7 can clamp and fix the rivet, thereby facilitating the subsequent removal work and improving the removal stability; the removal component 8 can remove the fixed rivet, improving the convenience of rivet disassembly, eliminating the need for manual removal, and saving time and effort in operation;

[0023] The pull-out assembly 8 includes a slide plate 81 installed inside the frame 1. Two sliders 82 are slidably connected to the slide plate 81. A bidirectional screw 84 is rotatably connected inside the frame 1 and threadedly connected to the sliders 82. A servo motor 85 is installed at one end of the frame 1, and the output shaft of the servo motor 85 is connected to the bidirectional screw 84. A rotating plate 83 is rotatably connected to one end of each slider 82, and both rotating plates 83 are connected to the connecting plate 5. The servo motor 85 drives the bidirectional screw 84 to rotate, causing the sliders 82 to slide on the slide plate 81 and the rotating plates 83 to rotate. This causes the connecting plate 5 to slide within the limiting hole 3 along with the limiting block 4, thereby pulling out the clamped rivet. The operation is convenient.

[0024] like Figure 2 As shown, in some embodiments, the clamping assembly 7 includes a slide block 71 that slides within a groove 6. A forward and reverse motor 78 is mounted on the connecting plate 5. A drive bevel gear 79 is mounted on the output shaft of the forward and reverse motor 78. A lead screw 74 is rotatably connected to each of the two grooves 6. The lead screw 74 is threadedly connected to the slide block 71. A connecting rod 76 is mounted between the two lead screws 74. A driven bevel gear 77 is mounted on the outer wall of the connecting rod 76. The connecting rod 76 is rotatably connected within the connecting plate 5. An extension plate 72 is mounted at one end of each of the two slide blocks 71. A clamping plate 73 is mounted at the end of each of the two extension plates 72. The forward and reverse motor 78 drives the drive bevel gear 79 to rotate, which in turn drives the driven bevel gear 77 to rotate, which in turn drives the connecting rod 76 to rotate, which in turn drives the lead screw 74 to rotate. This causes the slide block 71 to slide within the groove 6, thereby moving the clamping plate 73 via the extension plate 72. The clamping plate 73 is then fastened and fixed through the fastening hole, improving the stability of rivet removal.

[0025] like Figure 2 As shown, in some embodiments, the driving bevel gear 79 and the driven bevel gear 77 mesh with each other; this facilitates fixation.

[0026] like Figure 2 As shown, in some embodiments, the clamping plate 73 has a fastening hole, and the two clamping plates 73 are symmetrically arranged; the structure is simple.

[0027] like Figure 2 As shown, in some embodiments, the two lead screws 74 have opposite thread directions; this facilitates positioning.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
