The invention provides a longitudinal beam variable pitch adjusting device of an automobile carriage welding fixture. The longitudinal beam variable pitch adjusting device comprises a longitudinal beam distance locating mechanism, longitudinal beam variable pitch adjusting mechanisms and a fixture base, wherein two longitudinal beam variable pitch adjusting mechanisms are oppositely mounted on the left and on the right of the fixture base; each longitudinal beam variable pitch adjusting mechanism comprises an inner support plate and an outer support plate; horizontal moving shafts are mounted in guide holes of the inner support plate and the outer support plate and can slide; the inner end of the horizontal moving shaft is connected with a driving cylinder; a flange connected with the longitudinal beam distance locating mechanism is arranged on the horizontal moving shaft; an outward horizontal ejector pin is mounted on the inner support plate; the longitudinal beam distance locating mechanism comprises a base plate which is connected with a flange on the horizontal moving shaft; a stopping block guide rail is mounted on the base plate; the stopping block guide rail is connected with a stopping block driving cylinder; the lower part of the base plate is vertically connected with a cylinder bracket; the stopping block driving cylinder is mounted on the cylinder bracket; and a longitudinal beam locating plate is connected to the upper end of the base plate.
Description
technical field [0001] The invention relates to an automobile compartment welding jig longitudinal beam variable pitch adjusting device, in particular to the technical field of automobile compartment longitudinal beam assembly fixtures. Background technique [0002] With the diversification of automobile models, the types of automobile compartments are increasing. In order to be assembled with the frame longitudinal beams, the distance between the longitudinal beams of the carriages needs to be increased accordingly. The company currently has 6 sizes of the distance between the longitudinal beams of the carriages. Every kind of compartment longitudinal beam spacing must have a positioning spacing corresponding to it on the welding fixture. The positioning distance on the fixture is realized by controlling the relative positions of two sets of positioning blocks; [0003] At present, the positioning distance of general-purpose fixtures is mostly fixed, or the position of the...
