Embodiment Construction
[0024] control Figure 1-Figure 11 , the present invention provides a detection and correction device for a sub-frame of a freight car bogie. The device is composed of a base 6, a longitudinal rigid beam 7, a positioning component, a clamping component, a detection reference, and a correction component. The longitudinal rigid beam 7 is fixedly arranged on the base 6 Above, the positioning component, clamping component, detection reference and correction component are arranged on the base 6 and the longitudinal rigid beam 7 . A vertical positioning part 8 is arranged symmetrically at the left and right corresponding positions of the two short arms 2 of the sub-frame 1 on the device, and two longitudinal positioning parts 9 are symmetrically arranged at the long arms 3 of the sub-frame 1 on the device. A transverse positioning reference line 10 is set at the center of the sub-frame 1 . A vertical clamping lead screw 11 is arranged symmetrically above the corresponding positions...

The invention provides an auxiliary framework detection rectifying device of a truck bogie. The device consists of a base, a longitudinal steel beam, a locating part, a chucking part, a detection base and a rectification part, wherein the longitudinal steel beam is arranged on the base; the fixing part, the chucking part, the detection base and the rectification part are arranged on the longitudinal steel beam; the locating part comprises a vertical locating part, a longitudinal locating part and a transverse locating part; the chucking part comprises a vertical chucking part and a longitudinal chucking part; the rectification part comprises a transverse rectification screw rod and a vertical rectification screw rod. The device integrates functions of locating, chucking, detection and rectification, is easy to operate and is simple and convenient in detection means; by virtue of adopting a datum conversion means, the key size of a to-be-detected welded auxiliary framework group in auxiliary framework type truck bogie production is converted into a plan view size which is easy to detect from a spatial size; after out-of-tolerance is discovered, imposed deformation is performed on auxiliary frameworks by virtue of the rectification part, and heating is also performed, so that auxiliary frameworks are rectified to meet design requirements.
Description
Technical field: [0001] The invention relates to the field of freight car bogie manufacturing, in particular to a detection and forced correction device for sub-frame assembly and welding in the manufacture of sub-frame type freight car bogies. Background technique: [0002] In the production of the sub-frame of the existing sub-frame truck bogie, in order to meet the product design requirements, some key dimensions need to be inspected after the sub-frame is assembled and welded. If the size is found to be out of tolerance, it is generally corrected by flame heating. If these key dimensions are measured manually, there are disadvantages such as low work efficiency and poor accuracy; if infrared measurement or three-coordinate detection is used, there are disadvantages such as high requirements for the working environment, high procurement costs, and low efficiency. [0003] Therefore, in view of the sub-frame shape characteristics of the sub-frame truck bogie, it is of prac...
