[0002] An anti-roll torsion bar is a component installed at the bottom of a rail vehicle to resist the tendency to roll and thus maintain vehicle stability. Its main structure includes a torsion bar, a torsion arm, a spherical bearing, and a connecting rod. The torsion bar and the torsion arm are usually connected by interference fit, and two sets of torsion arms need to be symmetrically installed on a torsion bar. Before implementing the interference fit, the torsion arm needs to be heated and expanded. The heated torsion arm cannot be directly removed by hand and needs to be clamped and moved with a tool. This causes the operator's hand to be far away from the connection hole of the torsion arm. As a result, during the installation process, the shaking of the hand can easily cause the installation position to be inaccurate.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Utility Model Content

[0011] Furthermore, the positioning assembly includes two groups of movable rods that are movably connected to the V-shaped blocks, a limit baffle arranged at one end of the movable rod close to the centering plate, and a driving assembly arranged between the two groups of movable rods.

[0012] Furthermore, the driving assembly includes a second mounting bracket arranged on the side of the base plate, a second bidirectional threaded screw rotatably arranged on the second mounting bracket, and a connecting arm with one end arranged on the movable rod and the other end threadedly sleeved on the second bidirectional threaded screw and moving relatively synchronously; wherein a second rocker arm is installed at one end of the connecting arm.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-7 The anti-roll torsion bar assembly tool shown in the figure includes a base plate 1, on which are provided two groups of symmetrically placed V-shaped blocks 11 for erecting the torsion bar; two groups of centering plates 2 with limited sliding are provided on both sides of the base plate 1 along the long side direction, and the side ends of the two groups of centering plates 2 are provided with mutually cooperating transmission components so that the centering plates 2 can move relatively synchronously; the base plate 1 is also provided with a clamping component for clamping the torsion bar and a positioning component for positioning the torsion arm on the torsion bar. A limited sliding groove 21 is provided on the base plate 1. The middle plate 2 is clamped in the limiting slide groove 21 and slides in a limited position. Before the torsion arm is interference fit, the torsion bar is first placed on the V-shaped block 11, and then the two ends of the torsion bar are clamped by the middle plate 2 so that the torsion bar is located in the center position on the base plate 1. The torsion bar is then stabilized by the clamping assembly, and the installation position of the torsion arm is limited by the positioning assembly. After the torsion arm is put on the torsion bar, it can be accurately installed by limiting its position, which improves work efficiency and avoids the problem of inaccurate manual alignment.

[0027] In one embodiment, the transmission assembly includes auxiliary arm rods 3 respectively arranged at the side ends of the two groups of centering plates 2 and a gear 31 rotatably arranged on the base plate 1; the two groups of auxiliary arm rods 3 are staggered in parallel, and the opposite sides are provided with tooth surfaces 32 meshing with the gear 31. When the centering plate 2 on one side is moved, it drives the gear 31 to rotate through the tooth surface 32 on the side end auxiliary arm rod 3, and then the gear 31 drives the auxiliary arm rod 3 on the other side to move synchronously, thereby driving the centering plate 2 on the opposite side to move synchronously.

[0028] In one embodiment, the clamping assembly includes a first mounting frame 4 arranged in the center position of the base plate 1, a first bidirectional threaded screw 41 rotatably arranged on the first mounting frame 4, and two sets of clamping plates 42 threadedly sleeved on the first bidirectional threaded screw 41 and moving relatively synchronously; wherein a first rocker arm 43 is installed at one end of the first bidirectional threaded screw 41, and by rotating the first rocker arm 43, the first bidirectional threaded screw 41 is driven to rotate, thereby driving the two sets of clamping plates 42 to move synchronously relative to each other to clamp the torsion bar.

[0029] In one embodiment, the positioning assembly includes two groups of movable rods 5 that are respectively movably connected to the V-shaped block 11, a limit baffle 51 arranged at one end of the movable rod 5 near the centering plate 2, and a driving assembly arranged between the two groups of movable rods 5, the driving assembly includes a second mounting bracket 52 arranged on the side of the base plate 6, a second bidirectional threaded screw 53 rotatably arranged on the second mounting bracket 52, and a connecting arm 54 with one end arranged on the movable rod 5 and the other end threadedly sleeved on the second bidirectional threaded screw 53 and moving relatively synchronously; wherein one end of the connecting arm 54 is installed with a second rocker arm 55, when the second rocker arm 55 is rotated, the connecting arm 54 drives the two groups of connecting arms 54 to move synchronously relative to each other through rotation, and then the connecting arm 54 drives the limit baffle 51 to move through the movable rod 5, so that it can move to the position where the torsion arm needs to be installed on the torsion bar, and then after the torsion arm is sleeved on the torsion bar, it will be limited after moving to support the limit baffle 51, so that the torsion arms on both sides are installed symmetrically and the position is accurate.

[0030] In one embodiment, a base plate 6 is further provided at the bottom of the base plate 1. The base plate 1 is connected to the base plate 6 through supporting feet 61 provided at the four corners of the bottom surface, so that an overhead layer 62 is formed between the base plate 1 and the base plate 6; the middle part of the connecting arm 54 is provided in the overhead layer 62, and the connecting arm 54 is movable and walks between the overhead layers 62, thereby avoiding interference with the upper structure of the base plate 1.

[0031] In one embodiment, rubber pads 71 ​​with arc-shaped grooves 7 are provided on opposite sides of the two sets of clamps 42. The provision of the rubber pads 71 ​​strengthens the friction between the rubber pads 71 ​​and the torsion bar. At the same time, the arc-shaped grooves 7 allow for better engagement between the rubber pads 71 ​​and the surface of the torsion bar, making the clamps 42 more stable when clamping the torsion bar.

[0032] It will be apparent 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 considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
