[0044] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0045] See Figures 1 to 5 As shown;

[0046] This embodiment provides a width control device for a stainless steel car body underframe of a rail vehicle, the device comprising:

[0047] Crossbeam 1; and

[0048] Side beams 4 are movable and connected to both ends of the crossbeam 1 along its length.

[0049] Both sides of the crossbeam 1 and the side beam 4 are fixed with fixing blocks 2, and sliding blocks 3 are slidably connected inside the fixing blocks 2. The sliding blocks 3 are connected to the side beam 4.

[0050] An adjustment assembly 5 is provided between the crossbeam 1 and the side beam 4. This device adjusts the position of the side beam 4 on the opposite side through the adjustment assembly 5.

[0051] The device also includes:

[0052] Fixing component 6 is used to position and fix the side beam 4 after the side beam 4 is adjusted by the adjusting component 5, so as to maintain the position of the side beam 4.

[0053] Specifically, this embodiment discloses a control device for the width of a stainless steel chassis frame of a rail vehicle, which includes a crossbeam 1 and two side beams 4. The crossbeam 1 is provided with four fixing blocks 2, and a sliding block 3 is slidably connected inside the fixing blocks 2. At the same time, the device of this embodiment is designed with an adjustment component 5 and a fixing component 6. The adjustment component 5 is used to adjust the movement of the side beams 4, and after adjustment, the fixing component 6 can lock the adjustment component 5 to maintain the position of the side beams 4.

[0054] Preferably, in this embodiment, a fixing plate 7 is fixed at the middle position inside the crossbeam 1, and the internal space of the crossbeam 1 is divided into cavities on the left and right sides by the fixing plate 7, and an adjustment component 5 is provided in each cavity.

[0055] Preferably, the adjustment component 5 in this embodiment includes:

[0056] A fixing tube 51 that is close to and connected to the fixing plate 7;

[0057] A connecting rod 53 that passes through the crossbeam 1 and the fixed pipe 51 and is movable along the movable slots opened in the fixed pipe 51 and the crossbeam 1; and

[0058] A movable rod 54 is connected to the connecting rod 53, and the end of the movable rod 54 away from the connecting rod 53 is connected to the side beam 4;

[0059] A spring 52 is connected between the connecting rod 53 and the fixing tube 51.

[0060] First, this embodiment further defines the structure of the adjustment component, in which a fixed tube 51 is fixed inside the crossbeam 1. The fixed tube 51 is used to accommodate the spring 52 and the moving rod 54, and the fixed tube 51 and the crossbeam 1 are provided with a moving groove for the connecting rod 53 to pass through and slide to adjust the moving rod 54. When adjusting the position of the side beam 4, pulling the connecting rod 53 can drive the moving rod 54 to move, while compressing the spring 52. At this time, the moving rod 54 can drive the side beam 4 on the corresponding side to move.

[0061] The crossbeam 1 has a first moving groove 63 for the connecting rod 53 to move, and the fixed tube 51 has a second moving groove 16 for the connecting rod 53 to move.

[0062] Fixing component 6 includes:

[0063] The insertion rod 62 and the connecting rod 53 have an insertion hole 17 near their ends, and the insertion rod 62 can be inserted into the insertion hole 17;

[0064] The crossbeam 1 has sliding grooves 8 on both sides of the first moving groove 63. A clamping block 10 is provided in one sliding groove 8 and a moving block 61 is provided in the other sliding groove 8.

[0065] The locking block 10 can be slidably connected in the corresponding slide groove 8, and one end of the plug rod 62 is engaged with the locking groove 9 of the locking block 10;

[0066] The movable block 61 is driven to move along the corresponding slide 8 by the drive component, and the other end of the insert rod 62 can pass through the movable block 61.

[0067] Secondly, this embodiment further defines the structure of the fixing component 6, which is provided with a plug rod 62 that can pass through the insertion hole 17 of the connecting rod 53. One end of the plug rod 62 cooperates with the moving block 61, and the other end cooperates with the clamping block 10. By releasing the connection between the plug rod 62 and the connecting rod 53, the position of the connecting rod 53 can be adjusted at will. After adjustment, the moving block 61 and the clamping block 10 are used to restrict the movement of the plug rod 62 and the connecting rod 53, thereby maintaining the state of the adjusting component 5 and finally fixing the position of the side beam 4 after adjustment.

[0068] More preferably, the drive assembly of this embodiment includes a rotating rod 11 that passes through the crossbeam 1 and partially extends into the interior of the crossbeam 1; a first gear 12 connected to the end of the rotating rod 11; and a second gear 13 that meshes with the first gear 12, wherein the second gear 13 is connected to a threaded rod 14, and the threaded rod 14 is threadedly connected to the moving block 61 to drive the moving block 61 to move.

[0069] In this embodiment, the hole in which the movable block 61 mates with the insertion rod 62 is a through hole, and the hole in which the clamping block 10 mates with the insertion rod 62 is a threaded hole; the end of the insertion rod 62 is a threaded portion that mates with the threaded hole of the clamping block 10.

[0070] A support plate 18 is fixed at the middle position of the crossbeam 1.

[0071] When the position of the side beam 4 needs to be adjusted, the insert rod 62 is rotated to disengage it from the locking groove 9 of the locking block 10. Then, the insert rod 62 is slid and removed. Next, the connecting rod 53 is pushed, causing the moving rod 54 to slide inside the fixed tube 51, simultaneously compressing the spring 52. This causes the side beam 4 to move with the moving rod 54, thus adjusting its position. The connecting rod 53 is then fixed to prevent it from sliding freely. The rotating rod 11 is then rotated to drive the first gear 12 to rotate. 12 drives the second gear 13 to rotate, and the second gear 13 drives the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the moving block 61, it can drive the moving block 61 to move. When the moving block 61 moves to the designated position, the sliding rod 62 is slid in, so that the sliding rod 62 enters the insertion hole 17 and passes through the connecting rod 53. Then the sliding clamping block 10 moves to the position where the connecting rod 53 is engaged, connecting it to the clamping groove 9 of the clamping block 10. This makes the sliding rod 62 and the clamping block 10 tightly connected, thus completing the adjustment and fixation of the side beam 4.

[0072] In the above technical solution, the stainless steel car body underframe width control device for rail vehicles provided by this utility model has the following beneficial effects:

[0073] The device of this utility model adjusts the position of the two side beams 4 by adjusting component 5, and at the same time uses fixing component 6 to lock adjusting component 5 to maintain the adjusted position of side beam 4. This device effectively solves the problem of width dimension adjustment and post-weld adjustment and control during the manufacturing process of large components of rail vehicle underframe.

[0074] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
