Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Such as Figure 1-Figure 5 As shown in the figure, a bogie frame combined tire assembly includes mutually detachable beam pre-assembly devices 5 and a paired carcass;
[0027] The beam pre-assembly device 5 includes horizontal frames and longitudinal frames perpendicular to each other, and the horizontal frame and the vertical frame are in the shape of a "ten"; the beam pre-assembly device 5, the beam 16 and the paired carcass are detachably connected in sequence, The center of the crossbeam pre-assembly device 5 is consistent with the center of the paired carcass; the longitudinal frame is provided with a screw nut pair 1 for adjusting the distance between the longitudinal frame and the crossbeam; There are positioning holes. The bottom of the beam pre-assembly device 5 is also provided with a ball head 4, and the center of the ball head 4 is ...

The invention discloses a combined assembly jig of a bogie frame. The combined assembly jig comprises a cross beam pre-assembly device and an assembly jig body which can be separated from each other, wherein the cross beam pre-assembly device comprises a transverse frame and a longitudinal frame which are perpendicular to each other and adopt a cross-shaped structure; the cross beam pre-assembly device, a cross beam and the assembly jig body are detachably connected sequentially, and the center of the cross beam pre-assembly device is consistent with that of the assembly jig body; and the assembly jig body comprises a jig body, a side beam height positioning device, a side beam width positioning device, a side beam pressing device, a cross beam pressing device, an end beam height positioning device and an end beam width positioning device. The invention further discloses an assembly method of the combined assembly jig of the bogie frame. According to the combined assembly jig and the assembly method, the detachable cross beam pre-assembly device and the fixed assembly jig body constitute an assembly tool, problems of the difficult diagonal adjustment and the low assembly precision caused by traditional bogie frame assembly methods are solved, assembly with the method is quick and accurate, and the method is worthy of popularization.
Description
technical field [0001] The invention belongs to the field of bogie manufacturing and is used for pairing bogie frames. Background technique [0002] The Y25 bogie frame is a "day"-shaped structure, which is welded by a beam, two side beams and two end beams. There is a hole in the middle of the side beam, the cross beam is connected with the side beam, and the end beam is connected with the side beam. The conventional frame group pairing tire is a whole tire, the positioning and clamping unit of each part is set on the carcass, and the parts are put into the carcass in turn to complete the pairing. The problem with this method is that the lower center plate on the center of the crossbeam should be used as the positioning reference, but it is facing upwards and cannot be directly positioned by it, and can only be positioned by conversion. The design reference of this pairing method does not coincide with the pairing reference, it is difficult to guarantee the diagonal requi...
