[0023] See also Figures 1 to 5 The utility model provides a technical solution: a frog opening adjustment tool, comprising an intermediate pressure block 5, a left clamping block 1 for fitting on the left end 8 of the frog, and a right clamping block 2 for fitting on the right end 9 of the frog. Obviously, according to frogs of different numbers, the left clamping block 1 and the right clamping block 2 of the utility model can be designed to have corresponding sizes. The left clamping block 1 is butt-jointed with a left connecting block 3 through a parent-child structure, and the right clamping block 2 is butt-jointed with a right connecting block 4 through a parent-child structure. The left connecting block 3 and the right connecting block 4 have block inclined surfaces on the opposite sides; the intermediate pressure block 5 is respectively fitted with the block inclined surfaces of the left connecting block 3 and the right connecting block 4 through the bottom inclined surfaces on both sides of itself. In the present embodiment, the aspect ratio of the block inclined surface can be specifically 1:6.

[0024] In order to enable the left clamping block 1 to be well mounted on the left end 8 of the frog, the left clamping block 1 is provided with a left mounting notch 11, and the left mounting notch 11 has a left slot body inclined surface for matching with the rail waist side surface of the left end 8 of the frog; in order to enable the right clamping block 2 to be well mounted on the right end 9 of the frog, the right clamping block 2 is provided with a right mounting notch 21, and the right mounting notch 21 has a right slot body inclined surface for matching with the rail waist side surface of the right end 9 of the frog.

[0025] In order to realize the assembly and fixation between the left clamping block 1 and the left end 8 of the frog, a fastening bolt 6 is also installed on the outer wall of the left clamping block 1, and the end of the fastening bolt 6 extends into the left sleeve slot 11 and abuts against the rail waist side of the left end 8 of the frog; in order to realize the assembly and fixation between the right clamping block 2 and the right end 9 of the frog, a fastening bolt 6 is also installed on the outer wall of the right clamping block 2, and the end of the fastening bolt 6 extends into the right sleeve slot 21 and abuts against the rail waist side of the right end 9 of the frog.

[0026] In order to facilitate the removal and replacement of the left connecting block 3, a T-block 101 is fixedly arranged on the inner side of the left clamping block 1, and a T-slot 102 for cooperating with the T-block 101 is arranged at the corresponding position of the left connecting block 3; in order to facilitate the removal and replacement of the right connecting block 4, a T-block 101 is also fixedly arranged on the inner side of the right clamping block 2, and a T-slot 102 for cooperating with the T-block 101 is also arranged at the corresponding position of the right connecting block 4. Obviously, in this embodiment, the extension direction of the T-block 101 and the T-slot 102 is the vertical direction.

[0027] Of course, as other embodiments, the T-block 101 can also be fixedly set on the side wall of the left connecting block 3, and the inner side of the left clamping block 1 has a corresponding T-slot 102; similarly, the T-block 101 can also be fixedly set on the side wall of the right connecting block 4, and the inner side of the right clamping block 2 has a corresponding T-slot 102.

[0028] In order to facilitate the staff to clearly understand the specific situation of the frog opening adjustment, the front side walls of the left connecting block 3 and the right connecting block 4 are respectively provided with scale line rulers 7, and the front side wall of the middle pressing block 5 has scale marks 51 for cooperating with the scale line rulers 7.

[0029] The working principle of the utility model is as follows: first, the left clamping block 1 is installed on the left end 8 of the frog, so that the side of the rail waist of the left end 8 of the frog fits with the left groove body inclined surface inside the left clamping block 1, and the left clamping block 1 is fixed to the left end 8 of the frog by using the fastening bolt 6; similarly, the right clamping block 2 is installed on the right end 9 of the frog, so that the side of the rail waist of the right end 9 of the frog fits with the right groove body inclined surface inside the right clamping block 2, and the right clamping block 2 is fixed to the right end 9 of the frog by using the fastening bolt 6;

[0030] Then, the left connecting block 3 is connected to the left clamping block 1 through a parent-child structure, and the right connecting block 4 is connected to the right clamping block 2 through a parent-child structure, and the middle pressing block 5 is matched with the block inclined surfaces of the left connecting block 3 and the right connecting block 4 through the bottom inclined surfaces on both sides of itself;

[0031] When using this tool to enlarge the frog opening, Figure 4As shown, by applying force to the top surface of the middle pressure block 5 through an external top adjustment device such as a press, the height of the scale mark 51 on the middle pressure block 5 changes and decreases, and the corresponding values ​​of the scale line scales 7 on the connecting blocks on both sides are read to calculate the size change of the current frog opening.

[0032] Use this tool to adjust the frog opening. Figure 5 As shown, an external top adjustment device such as a press is used to simultaneously apply an inward working force to the outside of the left clamping block 1 and the right clamping block 2, thereby gradually reducing the opening size.

[0033] The reference for applying the force of the tooling is the side of the rail waist of the frog, which avoids direct action on the frog rail head or rail bottom to cause local deformation of the frog. The outer side walls of the left clamping block 1 and the right clamping block 2 are approximately perpendicular to the force direction of the external top adjustment device, ensuring the safety of the top adjustment. In addition, the structural design of the left connecting block 3 and the right connecting block 4 is reasonable, which ensures the integrity of the force transmission and avoids mutual interference between the frog rail bottom and the tooling. At the same time, by reading the corresponding value of the scale mark 7, the change of the opening size can be directly calculated, which improves the working efficiency and adjustment accuracy, ensures that the frog opening size is qualified, and is conducive to improving the overall quality of the frog assembly.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
