Simultaneously, each clamping component and each pressing component operate independently, facilitating alternating avoidance of the grinding and polishing device. When the grinding and polishing device moves to a certain clamping point… When the clamping or pressing component interacts with the elastic clamp of the railway turnout, the clamping or pressing component at that point retracts and avoids interference, providing sufficient working space for the grinding and polishing device. This does not affect the normal clamping or pressing of the railway turnout elastic clamp by the other clamping or pressing components. After the grinding and polishing device finishes grinding and polishing the area and continues to move forward through the area, the clamping or pressing component at that point resets and re-clamps or presses the railway turnout elastic clamp. Therefore, the positioning and clamping fixture for the railway turnout elastic clamp and its usage method provided by this invention can effectively improve the grinding and polishing efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The purpose of this invention is to provide a positioning and clamping fixture for a railway turnout elastic clamp and its usage method, so as to solve the problems existing in the prior art and effectively improve the grinding and polishing efficiency.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figures 1-2As shown, this embodiment provides a positioning and clamping fixture for a railway turnout elastic clamp, including several pressing components 1, several clamping components 2, and several supporting components 3. The supporting components 3 are arranged side by side and are used to support the railway turnout elastic clamp 5 and suspend the railway turnout elastic clamp 5. The clamping components 2 are arranged side by side on the first side of each supporting component 3. The number of clamping components 2 is equal to the number of supporting components 3. The clamping components 2 and supporting components 3 correspond one-to-one. Any clamping component 2 can clamp the first single side of the railway turnout elastic clamp 5 with the corresponding supporting component 3. The pressing components 1 are arranged side by side on the second side of each supporting component 3. The second side is opposite to the first side. Any pressing component 1 can press the second single side of the railway turnout elastic clamp 5 onto the supporting component 3.

[0032] The positioning and clamping fixture for the railway turnout elastic clamp provided in this embodiment supports the railway turnout elastic clamp 5 in the air with each supporting component 3, facilitating the grinding and polishing device to grind and polish the railway turnout elastic clamp 5. Any clamping component 2 can clamp the first single side of the railway turnout elastic clamp 5 with the corresponding supporting component 3, and any pressing component 1 can press the second single side of the railway turnout elastic clamp 5 onto the supporting component 3, ensuring the positioning and clamping of the railway turnout elastic clamp. At the same time, each clamping component 2 and each pressing component 1 operate independently, facilitating the alternating avoidance of the grinding and polishing device. When the grinding and polishing device moves to a certain clamping point... When the clamping component 2 or pressing component 1 interacts with the railway turnout elastic clamp 5, the clamping component 2 or pressing component 1 at that point retracts and avoids interference, providing sufficient working space for the grinding and polishing device. This does not affect the normal clamping or pressing of the railway turnout elastic clamp 5 by the other clamping components 2 or pressing components 1. After the grinding and polishing device finishes grinding and polishing the area and continues to move forward through the area, the clamping component 2 or pressing component 1 at that point resets and re-clamps or presses the railway turnout elastic clamp 5. Therefore, the positioning and clamping fixture for the railway turnout elastic clamp provided in this embodiment can effectively improve the grinding and polishing efficiency.

The top of the piston rod of the first longitudinal lifting cylinder 31 is fixedly connected to the limiting plate 32. The piston rod of the first longitudinal lifting cylinder 31 can drive the limiting plate 32 to rise and fall. The positioning groove 33 can perform initial coarse positioning of the railway turnout elastic clamp 5. The width of the positioning groove 33 is greater than the width of the first single side of the railway turnout elastic clamp 5, which can have a high tolerance for production consistency in the production process.

The piston rod of the third longitudinal lifting cylinder 13 can drive the second support plate 12 to rise and fall, which is convenient for manufacturing and use.

[0038] As a preferred embodiment of this invention, the positioning and clamping fixture for the railway turnout elastic clamp provided in this embodiment also includes a reference component 4. The reference component 4 is disposed on the third side of each support component 3. The third side is perpendicular to the first side and the second side.

[0042] Example 2

[0043] This embodiment provides a positioning and clamping method for a railway turnout elastic clamp, using the positioning and clamping fixture for the railway turnout elastic clamp in Embodiment 1, including the following steps:

[0044] Step 1: Place the railway turnout elastic clamp 5 onto each support component 3;

[0045] Step 2: Each clamping component 1 is activated, and any one clamping component 1 presses the second single side of the railway turnout elastic clamp 5 against the supporting component 3;

[0046] Step 3: Each clamping component 2 is activated, and any clamping component 2 and the corresponding support component 3 clamp the first single side of the railway turnout elastic clamp 5, thereby completely positioning and clamping the railway turnout elastic clamp 5.

When the grinding and polishing device moves to a certain clamping point... When the clamping component 2 or pressing component 1 interacts with the railway turnout elastic clamp 5, the clamping component 2 or pressing component 1 at that point retracts and avoids interference, providing sufficient working space for the grinding and polishing device. This does not affect the normal clamping or pressing of the railway turnout elastic clamp 5 by the other clamping components 2 or pressing components 1. After the grinding and polishing device finishes grinding and polishing the area and continues to move forward through the area, the clamping component 2 or pressing component 1 at that point resets and re-clamps or presses the railway turnout elastic clamp 5.
