The pressing seat 26 can vertically swing to effectively contact the lower bottom face with the top face of the side beam 92, so as to increase the pressing area and ensure the stability and effectiveness of the pressing action.

[0056] In one possible implementation, referring to Figures 1 to 11The high-speed rail bogie frame positioning device further comprises four sets of brake hanger clamping modules 5, which are respectively and correspondingly positioned at the inner sides of the four sets of four-corner leveling and alignment modules 2.

[0057] In the embodiment, the brake hanger clamping module 5 is further provided to ensure the accurate positioning of the brake hanger, since the brake hanger is further provided on the bogie frame. The brake hanger clamping module 5 is provided adjacent to the four-corner leveling and alignment module 2. The two embracing claws 53 can move towards each other along the Y direction to be clamped on both sides of the brake hanger, thereby achieving the clamping positioning of the brake hanger and ensuring the accurate positioning of each part of the whole frame 9.

[0064] In one possible implementation, please refer to Figures 1 to 11 The cross beam supporting module 4 includes two third Y-direction base plates 41, two third X-direction base plates 42, and two cross beam lifting supporting seats 43. The two third Y-direction base plates 41 are respectively connected to the tool base plate 1 in the Y-direction sliding mode, and the third Y-direction base plate 41 is connected to the tool base plate 1 through the third Y-direction pusher 44. The two third X-direction base plates 42 are respectively and correspondingly connected to the two third Y-direction base plates 41 in the X-direction sliding mode and are arranged in the Y-direction interval. The third X-direction base plate 42 is connected to the third Y-direction base plate 41 through the third X-direction pusher 45. The two cross beam lifting supporting seats 43 are respectively and correspondingly arranged on the third X-direction base plate 42 and are respectively arranged near the opposite corner positions of the third Y-direction base plate 41. The cross beam lifting supporting seat 43 has a supporting part 46 which can move up and down and is supported below the cross beam 91.

[0065] In this embodiment, the first Y-direction base plate 32 arranged on the tool base plate 1 drives the upper component to slide in the Y-direction, and the first X-direction base plate 31 drives the upper component to slide in the X-direction, so that the two cross beam lifting supporting seats 43 above can be supported below the two different positions of the cross beam 91, which is suitable for supporting the cross beam 91 of different specifications of the frame 9, improves the stability of the cross beam 91 support, and ensures the positioning accuracy of the frame 9. The above structure is convenient to adjust and simple to use, which can effectively ensure the positioning accuracy of the frame 9.

[0066] The two cross beam lifting supporting seats 43 are respectively and correspondingly arranged on the two first X-direction base plates 31. A straight line arranged in the X-direction and passing through the center of the tool base plate 1 is defined as the central axis of the tool base plate 1. The two cross beam lifting supporting seats 43 are distributed on both sides of the central axis (that is, arranged in the interval in the direction of the cross beam 91). Since the middle part of the cross beam 91 is generally provided with a hole passing through up and down, the two cross beam lifting supporting seats 43 are distributed on both sides of the hole (that is, arranged in the interval in the X-direction), which can reliably support different points of the cross beam 91 and improve the reliability of the support.

[0067] On this basis, the two sides of the tooling base plate 1 are provided with the alignment robot 7, the alignment robot 7 uses a visual camera at an extended end to take pictures of each part of the frame 9, so as to cooperate with the frame 9 to perform position alignment, improve the alignment efficiency, and ensure the alignment accuracy.

[0068] Based on the same inventive concept, the application also provides a high-speed rail bogie frame positioning method, which comprises the following steps:

[0069] S100: presetting standard center coordinates of the frame, first standard coordinates of the cross beam, and second standard coordinates of the side beam;

[0070] S200: using the four-corner leveling alignment module to perform horizontal displacement of the component in the X direction and the Y direction, and combining with the circumferential rotation driving of the frame to realize horizontal alignment;

[0071] S300: using the up-down movement of the four-corner leveling alignment module to realize the lifting adjustment of the frame, so that the actual center coordinates of the frame coincide with the standard center coordinates, the first actual coordinates of the cross beam coincide with the first standard coordinates, and the second actual coordinates of the cross beam coincide with the second standard coordinates;

[0072] S400: using a visual camera to take pictures of the frame and performing secondary alignment of the frame;

[0073] S500: after the secondary alignment is completed, the error satisfies the preset interval, the positioning of the frame is determined to be qualified, the cross beam and the side beam of the frame are compressed and positioned, and the frame positioning is completed.

[0074] Installation process:

[0075] When the frame 9 is installed on the tooling base plate 1, the standard center coordinates of the frame 9 and the first standard coordinates of the cross beam 91 and the second standard coordinates of the side beam 92 are preset, so that the overall position of the component 9 is effectively limited. Taking the side beam 92 as an example, the first standard coordinates can select a specific side edge or end of the longitudinal beam 92 as a reference to perform position calibration in the X, Y and Z directions, so as to ensure the accuracy of the preset standard position of the longitudinal beam 92.

[0076] After the frame 9 is installed, the position of the frame 9 needs to be horizontally aligned and adjusted in height by using the four-corner leveling alignment module, so as to preliminarily reach the preset position. In this process, the horizontal movement of the second X-direction base plate 61 and the second Y-direction base plate 62 is used to adjust the position of the frame 9 in the X and Y directions, the end part of the side beam 92 is pushed by the end part block 22 and the side displacement block 21 to make the frame 9 rotate around the center, so as to realize the adjustment of the angle.

[0077] Afterwards, the lifting of the lifting belt supporting the base 23 drives the frame 9 to move up and down to the target height, so that the zero point of the frame 9 coincides with the preset zero point, leveling and positioning are completed. After the first alignment is completed, the visual camera is used to take a picture for secondary alignment. After the secondary alignment is completed, the picture is rechecked to ensure that the error is less than 0.2mm, and it is determined that the positioning is qualified. Finally, the middle and end parts of the cross beam 91 and the side beam 92 are pressed and limited, and the accurate positioning of the frame 9 is completed.

[0078] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
