Description
Technical Field
[0001] The invention relates to the technical field of construction instruments and equipment, in particular to a press-fitting tooling platform for anti-snake shock absorbers of electric train sets. Background Art
[0002] During the 600,000-kilometer special repair of the EMU anti-snaking shock absorber, it is necessary to dismantle the vehicle for a low-speed test of the anti-snaking shock absorber. Under specific vibration conditions, the attenuation damping force of the oil pressure shock absorber in both compression and tension states is tested. After passing the test, due to a significant change in the installation length of the shock absorber, when it is subsequently installed back on the corresponding bogie frame side, it is necessary to manually compress the anti-snaking shock absorber with both hands so that the shock absorber can normally fall into the corresponding mounting seat groove. The manual operation is inefficient, and a total of 6 people are required to work at the same time (3 on each side) to restore the shock absorber on both sides, affecting the installation progress. This operation on ordinary EMUs takes 192-320 minutes, and in the process of manually docking the shock absorber sleeve and sleeve, it is difficult to accurately position them due to the heavy weight of the equipment itself, which will cause multiple interface collisions between the two, thereby damaging the sleeve interface and causing significant economic losses. In addition, the subsequent manual measurement after compression still cannot determine the completeness of the compression return with high precision, thus affecting the process of assembly on the vehicle.

[0045] Please refer to the attached Figure 3 , Figure 4 , including a bottom platform base and a driving box, the bottom platform base includes two parallel side trusses, the driving box and the end positioning group are respectively fixed above the two ends of the side trusses, and the outside of the driving box is provided with two positioning slide bars parallel to the side trusses, and the other ends of the two positioning slide bars are fixed to the end positioning group;
[0046] The positioning slide rod is sleeve-connected with a movable group, which includes a double-sided movable frame. A main driving cylinder is arranged inside the driving box, and the protruding end of the main driving cylinder passes through the driving box and is fixedly connected to the side of the double-sided movable frame.
