[0031] The present application is further described in detail below in conjunction with all the drawings and specific embodiments.

[0032] Reference Figure 1 The present invention provides a rail end face grinding machine for grinding the end face of a rail to facilitate subsequent rail welding. The rail end face grinding machine includes a clamping body 1, a guide post 5, a fixing frame 2, a motor 3, and a grinding wheel 4. The clamping body 1 is used to fix the rail, the fixing frame 2 is used to mount the motor 3 and the grinding wheel 4, and the guide post 5 can limit the position of the clamping body 1 and the fixing frame 2, thereby limiting the position of the rail and the grinding wheel 4, allowing the grinding wheel 4 to grind the end face of the rail.

[0033] The card body 1 and the fixing frame 2 can be connected through the guide column 5. The arrangement direction of the card body 1 and the fixing frame 2 is the first direction a. The axial direction of the guide column 5 is the first direction a. The guide column 5 is respectively provided in the card body 1 and the fixing frame 2, so that the card body 1 and the fixing frame 2 can adjust the relative position along the first direction. The guide column 5 can limit the relative position of the card body 1 and the fixing frame 2, so that after the rail is installed, the rail and the grinding wheel 4 can accurately adjust the relative position along the first direction a.

[0034] The clamp body 1 is provided with a mounting groove 11, in which the rail can be fixed. The motor 3 and the grinding wheel 4 are mounted on the fixing frame 2. The grinding wheel 4 is located on the side of the fixing frame 2 close to the clamp body 1, and the output shaft of the motor 3 is fixed to the grinding wheel 4. During operation, the worker can first fix the rail in the clamp body 1, and adjust the distance between the clamp body 1 and the fixing frame 2 along the guide column 5 so that the grinding wheel 4 can contact the rail. The driving motor 3 drives the grinding wheel 4 to rotate, so that the grinding wheel 4 can grind the end face of the rail. The position of the grinding wheel 4 can be adjusted by rotating the entire fixing frame 2, so that the end face of the rail can be fully and widely grinded. The rail end face grinder of the present application can be fixed on the rail to grind the end face of the rail, reducing the labor intensity of the workers and improving work efficiency.

[0035] It should be noted that the shape of the mounting groove 11 is not fixed. As long as the mounting groove 11 matches the shape of the rail, the shape of the mounting groove 11 can be adjusted according to rails of different specifications.

[0036] As an embodiment, the motor 3 is a lithium battery powered motor, which makes the motor 3 more applicable and requires a smaller site. It should be noted that the lithium battery powered motor is a prior art and the internal structure and circuit are not described in detail in this application.

[0037] Reference Figure 2 and Figure 3 As an embodiment, a threaded hole 12 is formed on one side of the card body 1. The threaded hole 12 is connected to the mounting groove 11. A screw rod 13 is threadedly connected to the threaded hole 12. The screw rod 13 can tighten the rail to position the rail in the mounting groove 11. Furthermore, a crank handle 14 is fixed to one end of the screw rod 13, which can facilitate the worker to apply force.

[0038] As an embodiment, the guide post 5 is rotatably connected to the fixed frame 2, and a through slot 15 is provided in the clamp body 1. The guide post 5 is inserted into the through slot 15, and the guide post 5 abuts against the inner side of the through slot 15. The guide post 5 is rotatably connected to the clamp body 1, so that the guide post 5 can only rotate relative to the clamp body 1. The guide post 5 is inserted into the through slot 15 and abuts against the through slot 15. The guide post 5 and the inner wall of the through slot 15 have a certain friction force, so that the guide post 5 can stably move in the through slot 15 along a first direction. When grinding the end face of the rail, since the clamp body 1 is already fixed to the rail, the position of the clamp body 1 is not easy to move. The guide post 5 moves in the through slot 15, which can drive the fixed frame 2 as a whole to move along the first direction a, adjust the distance between the grinding wheel 4 and the rail, and at this time, the fixed frame 2 can rotate along the guide post 5, so that the grinding wheel 4 swings, and adjusts the position of the ground rail end face. Furthermore, the guide post 5 is connected to the through slot 15 by sliding along the first direction a, so that the guide post 5 can only slide along the first direction a relative to the card body 1. It should be noted that the sliding structure can be a structure in which a slide bar and a slide groove cooperate, but is not limited thereto. The sliding structure is an existing structure and will not be described or illustrated in detail in this application.

[0039] Reference Figure 3-Figure 5 As an embodiment, a rotating wheel 16 is rotatably connected to the interior of the clamp body 1. The axis direction of the rotating wheel 16 is perpendicular to the axis direction of the guide column 5. A groove 51 is provided on the upper side of the guide column 5, and the rotating wheel 16 can be placed in the groove 51. A plurality of ridges 52 are fixed in the groove 51. A plurality of slots 161 are provided on the surface of the rotating wheel 16. The ridges 52 can be engaged in the slots 161. When rotating, the slots 161 and the ridges 52 cooperate to push the guide column 5 to drive the fixed frame 2 to move stably along the first direction a, stably adjusting the position between the grinding wheel 4 and the rail. In this way, the position of the grinding wheel 4 and the end face of the rail can be adjusted while the rail and the clamp body 1 are fixed. Furthermore, a handwheel 162 is rotatably connected to one side of the clamp body 1. The connecting shaft of the handwheel 162 is fixed to the rotating wheel 16. Rotating the handwheel 162 can facilitate the worker to operate and move the guide column 5.

[0040] Reference Figure 1 As an embodiment, the fixing frame 2 includes a horizontal plate 21 and a vertical plate 22. The horizontal plate 21 and the vertical plate 22 are arranged perpendicular to each other and fixed. The guide column 5 is disposed through the horizontal plate 21. The side wall of the motor 3 is fixed to the vertical plate 22, and the end face of the motor 3 is fixed to the horizontal plate 21. The output shaft of the motor 3 extends to the side of the horizontal plate 21 near the clamp body 1 and is fixed to the grinding wheel 4. The fixing frame 2 composed of the horizontal plate 21 and the vertical plate 22 has a simple structure and can stably install the motor 3.

[0041] As an embodiment, a rotating sleeve 211 is fixed on the horizontal plate 21, and the rotating sleeve 211 is coaxially arranged with the guide column 5. The guide column 5 is passed through the horizontal plate 21 and is rotatably connected to the rotating sleeve 211. A pull rod 212 is fixed to the rotating sleeve 211. Pulling the pull rod 212 can drive the rotating sleeve 211 to rotate. The rotation of the rotating sleeve 211 can drive the entire fixed frame 2 and the guide column 5 to rotate relative to each other, thereby driving the grinding wheel 4 to rotate, so that the grinding wheel 4 can grind the end face of the rail.

[0042] The implementation principle of the present invention is as follows: when working, the rail can be fixed in the clamp body 1 first, and the distance between the clamp body 1 and the fixing frame 2 can be adjusted along the guide column 5 so that the grinding wheel 4 can contact the rail. The driving motor 3 drives the grinding wheel 4 to rotate, so that the grinding wheel 4 can grind the end face of the rail, and the position of the grinding wheel 4 can be adjusted by rotating the entire fixing frame 2, so that the end face of the rail can be fully and widely grinded. The rail end face grinder of the present application can be fixed on the rail to grind the end face of the rail, thereby reducing the labor intensity of workers and improving work efficiency.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
