Embodiment Construction
[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0030] to combine Figure 2 to Figure 5 As shown, a rail vehicle side frame processing and clamping device includes a base 1, a load-bearing platform 2 is provided in the middle of the base 1, and two automatic centering devices 3 are provided on the load-bearing platform 2, one in front and the other in the rear. The middle device 3 includes a limit frame 30 erected on the load-bearing platform 2. The inner top of the limit frame 30 is provided with an upper arm connecting shaft 31, and two upper arms 32 are movably connected to the upper arm connecting shaft 31. The lower ends of the two upper arms 32 are respectively movably connected with the lower arms 33, and the lower ends of the lower arms 33 are provided with a lower arm connecting bloc...

The invention discloses a railway vehicle side frame machining clamping device which comprises a base. A bearing table is arranged at the middle position of the base. Two automatic centering devices are arranged on the bearing table in a front and back manner. Each automatic centering device comprises a limiting frame. An upper rotating arm connecting shaft is arranged at the internal top end of each limiting frame. Two upper rotating arms are movably connected to each upper rotating arm connecting shaft, wherein the lower ends of the two upper rotating arms are movably connected with lower rotating arms correspondingly, lower rotating arm connecting blocks are arranged at the lower ends of the lower rotating arms, the two lower rotating arms are movably connected to the lower rotating armconnecting blocks, and the lower ends of the lower rotating arm connecting blocks are connected with first air cylinders. A rotating device is arranged at the left end of the base, and a rotating device is arranged at the right end of the base. According to the clamping device, in the using process, side frames can be controlled to be fixed to the middle position automatically, the side frames can be fixed in an all-around manner, it is ensured that in the face milling process, the side frames will not deviate or move, and the machining precision is improved. Two side frames can be machined at the same time, the production efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of mechanical processing of railway vehicle accessories, in particular to a processing and clamping device for railway vehicle side frames. Background technique [0002] The side frame is an important part of the railway vehicle bogie system. Its performance and reliability have an important impact on the technical level of the railway vehicle, and its quality is directly related to the driving safety of the railway vehicle. [0003] like figure 1 As shown, it shows the plan view of the side frame of the railway vehicle, which requires a special fixture to fix it during milling, and the quality of the fixture is related to the accuracy of the processed product. At present, the mechanical processing technology of the inner frame in the industry mainly includes the positioning of the two facades of the central frame, and the double-sided fixing of the central frame in the middle of the side frame. However, d...
