[0002] At present, the side wall of rail transit vehicles is composed of an exposed part that wraps the side of the vehicle body, has a smooth curvature, and various windows, drain holes and other holes are also scattered on it. Different from other parts, such as the attached Figure 1 , 2 As shown, the side wall component has a relatively large shape and is a thin-walled, hollow part. When the side wall component is a thin-walled aluminum profile structure, its strength is relatively low compared to other components. During the processing, it vibrates greatly, generates strong noise, is difficult to clamp, and is prone to deformation.

[0003] In the prior art, simple pads, pressure plates and screws are usually used to fix the side wall components, and noise reduction is achieved by adding a soundproof cover to the machine tool. The above measures have the following defects:

[0004] 1) In the traditional fixing method, the pads are easy to form line contact with the surface of the side wall component, and the side wall component is easy to deform due to excessive force, which leads to poor processability, large deformation during processing, serious noise, and loose clamping, which makes the side wall component easy to move during processing, resulting in irreparable defects such as gnawing, resulting in waste, low production efficiency and high cost;

[0005] 2) When using a soundproof cover to reduce noise, it is not only costly, but also inconvenient to observe the side wall composition, affecting production efficiency;

[0006] Therefore, in response to the above problems, it is necessary for the present invention to provide a thin-walled aluminum profile side wall processing tooling that can reduce the noise generated during the mechanical processing of the workpiece, has firm and stable clamping, high versatility, and is beneficial to improving the processing quality of the workpiece.

An adapting support member 23 is movably connected to the bracket 22 at the clamping mechanism side. That is, the end of the bracket 22 corresponding to the upward warping of the workpiece 100 is movably connected to the adapting support member 23. The warping angle of the workpiece 100 is adapted by the adapting support member 23 to avoid the warping end of the workpiece 100 from being suspended in the air, so that the bracket 22 keeps in line with the structure of the workpiece 100, stably supports the workpiece 100, reduces vibration and noise during the processing of the workpiece 100, reduces the impact on the physical and mental health of the staff, and at the same time, avoids deformation of the workpiece 100 during clamping and processing, thereby ensuring the quality of the workpiece 100, improving the qualified rate of the workpiece 100, as well as the service life of the tool and the machine tool, and saving production costs.

[0064] The positioning member 222 can be used in the prior art to realize that the extension arm 233 and the bracket 22 can be detachably fixedly connected to the positioning member, so as to adjust the angle of the supporting member 23. In this embodiment, preferably, the positioning member 222 is a bolt, and the bolt cooperates with the nut to make the extension arm 233 and the bracket 22 detachably fixedly connected. Preferably, the extension arm 233 is constructed to be an arc-shaped structure with the pin shaft 221 as the center, and the extension arm 233 has an arc-shaped positioning hole 234 for cooperating with the positioning member 222, and the extension arm 233 is also formed with a notch with a width matching the width of the bracket 22, that is, during assembly, see Figure 6 As shown, the positioning member 222 passes through the positioning hole 234 on the extension arm 233 and the bracket 22, and the nut is tightened, and the extension arm 233 clamps the bracket 22 from both sides of the bracket 22;

[0066] Both ends of the bottom plate 21 are fixedly connected with a clamping mechanism, and two brackets 22 are arranged on the bottom plate 21 between the two clamping mechanisms. Both brackets 22 have an adaptable support member 23 .

[0067] Specifically, the bottom plate 21 is a rectangular plate-shaped body, and two groups of clamping mechanisms and two groups of brackets 22 are integrated on the bottom plate 21, that is, the clamping mechanism and the bracket 22 are fixedly connected to the platform 1 through the bottom plate 21. Preferably, a plurality of slideways 11 are evenly distributed on the upper surface of the platform 1, and the slideways 11 extend along the length direction of the platform 1.

[0069] Specifically, in this structure, the bracket 22 is a hollow structure, which is convenient for reducing the overall weight of the tooling. Secondly, a long hole 223 is opened on the lower surface of the bracket 22, which is convenient for adjusting the position of the bracket 22 along the width direction of the platform 1 to adapt to different types of workpieces 100, which is conducive to ensuring the versatility of the tooling;

[0070] See also Figure 5 As shown, preferably, the pressing mechanism includes a first positioning column 24 for pressing the workpiece 100 in a vertical direction and a second positioning column 25 for pressing the workpiece 100 in a horizontal direction;

[0071] A first screw rod 241 is threadedly connected to the top of the first positioning column 24, and a second screw rod 242 is threadedly connected to the first screw rod 241. The second screw rod 242 contacts the upper surface of the workpiece 100 through the pressing block 30.

[0072] A pressing block 30 is disposed on the side of the second positioning column 25 for contacting the side surface of the workpiece 100 .

[0073] Specifically, in this structure, see Figure 8 As shown, the first positioning column 24 is provided with two screw rods, a first screw rod 241 and a second screw rod 242. The first screw rod 241 is threadedly connected to the top of the first positioning column 24 in parallel with the horizontal plane, and the second screw rod 242 is vertically threadedly connected to the end of the first screw rod 241.

In order to ensure the appearance quality of the workpiece 100, the second screw rod 242 of the first positioning column 24 and the second positioning column 25 are pressed by the block 30 to contact the workpiece. The block 30 can be made of non-metallic nylon to prevent indentation on the surface of the workpiece 100 and offset some vibration, thereby greatly reducing noise.

Of course, according to the use requirements, the two second positioning columns 25 can also be provided with a third screw rod 251. In this structure, the distance between the two second positioning columns 25 is adjusted by the third screw rod 251, which is suitable for workpieces 100 of different models and improves the versatility of the tooling. When in use, the third screw rod 251 is adjusted, and the two second positioning columns 25 press the workpiece 100 from the side of the workpiece 100, thereby improving the positioning stability of the tooling, reducing noise, and ensuring the processing quality.
