specific Embodiment approach

[0065] See Figure 6 to Figure 8 and Figure 10 to Figure 13 As a specific embodiment of the bogie frame assembly tool provided by the present invention, the locking assembly includes a first stud 230 fixed on the second clamping block 220 and a first screw threaded with the first stud 230 . The nut 240 and the first clamping block 210 are provided with a first through hole through which the first stud 230 passes.

[0066] The first nut 240 is located on the side of the first clamping block 210 away from the second clamping block 220, and the first nut 240 is threaded with the part of the first stud 230 protruding from the first clamping block 210, so that the first clamping block 210 is screwed. When there is a nut 240 , the first nut 240 will abut against the first clamping block 210 , and the first clamping block 210 will clamp and fix the beam on the second clamping block 220 (inside the V-shaped groove 221 ).

[0067] See Figure 13 , as a specific embodiment of the bogi...

Abstract

The invention belongs to the field of locomotive manufacturing, and provides a bogie frame assembling tool and a bogie frame assembling method. The bogie frame assembling tool comprises a machine frame, a cross beam accompanying clamping mechanism, a positioning assembly, a side beam assembling mechanism, an axial positioning moving mechanism and an axial clamping mechanism. According to the bogieframe assembling tool, the cross beam accompanying clamping mechanism for positioning and clamping a cross beam assembly and the side beam assembling mechanism for positioning and clamping a side beam assembly are arranged, the positioning assembly for positioning the cross beam accompanying clamping mechanism and the axial positioning moving mechanism for driving the side beam assembling mechanism to move and positioning the side beam assembly to a preset mounting position relative to the cross beam assembly are arranged, so that the cross beam assembly and the side beam assembly are positioned and assembled, and complex manual lineation positioning and tedious and heavy carrying operation are avoided.

Description

technical field [0001] The invention belongs to the field of locomotive manufacturing, and more specifically relates to a bogie frame assembly tool. Background technique [0002] The bogie frame is welded by steel plates, steel pipes, forgings, castings and other metal parts. It is mainly composed of beams and side beams, and the process quality control requirements are strict. The assembly error in the welding process of the frame affects the size of the finished frame. The size of the frame affects whether the processing of the frame is sufficient or whether it will be overcut. It also affects the assembly of the bogie. The assembly size of the frame is mainly guaranteed by the tooling, and the assembly method also affects the assembly accuracy of the frame . [0003] See figure 1 , the state of the frame when the bogie is in the forward position is the forward position of the frame, otherwise, the state of the frame in the reverse position of the bogie is the reversed s...
