[0026] Refer to the attached Figures 1-3, A track frog repair device, including a base 1, a robotic arm 2 is assembled on the base 1, and a welding machine 3 and a scanner 6 are arranged at the end of the robotic arm 2 for scanning and welding repair of the track frog body 4 placed on the top of the base 1;

[0027] A clamping mechanism 5 is arranged on the top of the base 1. The clamping mechanism 5 includes a vertical rod 51. A movable plate 52 is rotatably installed at the top of the vertical rod 51. A clamping plate 54 is arranged at the bottom of the movable plate 52. The number of the clamping plates 54 is two, and they are driven to move closer to clamp inside the track frog body 4;

[0028] A threaded groove 5201 communicating with its rotating shaft is formed on the movable plate 52, and a positioning bolt 53 is in threaded connection with the threaded groove 5201.

[0029] In this embodiment, after the track frog body 4 is placed on the top of the base 1, the two clamping plates 54 are driven to move closer and clamp inside the track frog body 4 to fix it. Then, the scanner 6 at the end of the robotic arm 2 is driven by the robotic arm 2 to scan the track frog body 4, and the welding machine 3 is used to weld and repair the scanned damaged parts. Moreover, the movable plate 52 at the top of the vertical rod 51 can rotate and is locked by the positioning bolt 53, so as to adjust the angle. The two clamping plates 54 are synchronously adjusted in angle, so that the clamping angle can be changed, and it can be used to clamp track frog bodies 4 with different angle specifications, and the application range is wide.

[0030] The number of the clamping mechanisms 5 is several and they are distributed relatively, so that multiple parts on both sides of the track frog body 4 can be fixed, and the fixing effect is good.

[0031] The clamping mechanism 5 includes two sliders 55, which are respectively fixedly connected to the two clamping plates 54. The two sliders 55 are slidably connected to a chute 5202 formed at the bottom of the movable plate 52, and are in threaded connection with a first lead screw 56 rotatably installed in the chute 5202 in opposite directions. One end of the first lead screw 56 extends to the end of the movable plate 52 and is provided with a first handle 57.

[0032] In this embodiment, after the first handle 57 is rotated, the first lead screw 56 rotates synchronously, which can drive the two sliders 55 to slide in the chute 5202. Since the two sliders 55 and the first lead screw 56 are in threaded connection in opposite directions, the two sliders 55 will move relatively, and the two clamping plates 54 will move relatively synchronously.

[0033] Considering that the two clamping plates 54 cannot be parallel to the frog body 4 after angle adjustment, a small gap will be generated between the clamping plates and the frog body 4 during clamping, which will affect the clamping effect. The rubber pads 58 provided on the clamping sides of the clamping plates 54 can fill the gap through pressure deformation, so as to ensure the stability of clamping and fixing.

[0034] The clamping mechanism 5 further includes a U-shaped frame 59 fixedly installed on the top of the base 1. The vertical rod 51 is slidably installed on the U-shaped frame 59. A connecting plate 510 is fixedly installed in the U-shaped frame 59. A second lead screw 511 is rotatably installed on the connecting plate 510. One end of the second lead screw 511 is threadedly connected to the bottom of the vertical rod 51, and the other end is provided with a second handle 512.

[0035] In this embodiment, after rotating the second handle 512, the second lead screw 511 rotates synchronously, so as to drive the vertical rod 51 to slide on the U-shaped frame 59 to realize lifting and lowering. The two clamping plates 54 are lifted and lowered synchronously, and can abut against the bottom of the frog body 4 with different depth specifications, so as to ensure the clamping area with the frog body 4 and ensure the stability of clamping.

[0036] The above embodiments only represent a certain implementation mode of the present invention, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.

[0037] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art.
