The invention relates to the technical field of internal combustion locomotives, in particular to an air duct model clamping tool for an internal combustion locomotive ventilation experiment. The air duct model clamping tool comprises a base, a middle beam, front supports and rear supports. The middle beam is installed at the top of the base, the front supports and the rear supports are connected to the two sides of the base respectively, a cross beam of the base is of a groove-shaped rail structure, guide rails are arranged on end beams, a supporting plate is embedded into the middle beam, clamping rods and positioning bolts are arranged on the front supports, pressing arms and lead screws are arranged on the rear supports, and clamping rods are arranged on the pressing arms. The base, the middle beam, the front supports and the rear supports are designed and combined into an adjustable rack tool capable of clamping complex box type air duct models of various sizes. In the using process, the air duct model clamping tool can be supported and adjusted through vertical supports. Then, the pressing arms press air duct models. All the portions can be flexibly adjusted, one device can meet the clamping requirements of air duct models of various shapes, use is easy and convenient, adaptability is greatly improved, and the experiment period is shortened.
Description
technical field [0001] The invention relates to the technical field of diesel locomotives, in particular to an air duct model clamping tool for ventilation experiments of diesel locomotives. Background technique [0002] The experimental capability of the ventilation system is crucial to the optimization design of the related performance of the diesel locomotive. The air duct models of diesel locomotives are all irregular and complex box shapes, and the existing test benches are all fixed and non-adjustable structures. Different models need to be equipped with different clamping benches, which not only increases the cost of the experiment, but also prolongs the experiment period. Contents of the invention [0003] In order to overcome the disadvantages of inflexible use, high cost and long test period of the existing air duct model test bench, the present invention provides an air duct model clamping tool for the ventilation experiment of a diesel locomotive. [0004] The...
