SUMMERY OF THE UTILITY MODEL
In order to solve the rail passenger train draw beam major part after the welding and detecting the critical dimension in-process, the existence detects the precision poor, to measuring personnel skill level require high, the testing process is complicated, inefficiency, can't realize accurate the detecting of centering, detect with high costs technical problem, the utility model provides a rail passenger train draw beam major part critical dimension detection device can greatly improve detection efficiency, practices thrift the cost, realizes the accurate the detecting of major part critical dimension's centering.
The utility model provides a technical scheme as follows that technical problem took:
the device for detecting the key size of the large part of the traction beam of the railway passenger car is characterized by comprising a cross beam, two reference scales, two fixed blocks, a plurality of lateral tightening bolts, a plurality of vertical tightening bolts, two linear guide rails and two sliding blocks; a beam central line is carved on the side wall of the beam, the two linear guide rails are fixedly connected to the upper end surfaces of the two ends of the beam respectively, and the two sliding blocks are in one-to-one correspondence to be in sliding connection with the two linear guide rails; the bottom one-to-one of two fixed blocks links firmly the up end at two sliders, and the one end of two reference scales all links firmly on the upper portion of two fixed blocks through side direction puller bolt and vertical puller bolt one-to-one, and the other end of two reference scales is parallel.
The reference ruler is of an L-shaped or T-shaped structure. The fixed block is of a hollow square block structure, a horizontal threaded hole used for installing a lateral tightening bolt and a vertical threaded hole used for installing a vertical tightening bolt are formed in the fixed block, and one end of the reference scale is inserted into the fixed block and is tightly fixed through the lateral tightening bolt and the vertical tightening bolt.
The utility model has the advantages that: the design reference of the large traction beam component is used as a detection reference by the detection device, the detection reference does not need to be determined manually, the center of the detection device coincides with the center of the large traction beam component in the detection process, and after the detection surfaces of the two reference scales of the detection device completely coincide with the detected surface of the large traction beam component, the size between the detected surfaces of the large traction beam component can be determined by measuring the size between the detection surfaces of the two reference scales. The utility model provides the high detection precision, the testing process is simple, has improved detection efficiency, can realize the centering accuracy detection of major part critical dimension, has reduced the detection cost.
