Example Embodiment

[0024] The present invention will be further described below in conjunction with the accompanying drawings of the specification.

[0025] Such as figure 1 As shown, a welding tooling fixture for an eight-axis bogie frame of an electric locomotive includes a support frame 1. The support frame 1 includes two side beams 11 arranged in parallel and a cross beam 12 arranged in parallel between the two side beams 11 , The end beams 14 respectively arranged at the two ends of the side beams 11 and the connecting seat 15 arranged in the middle of the end beams 14 to connect to the rotating equipment, and two parallel connecting beams 13 are arranged between the two cross beams 12. The side beams 11, the cross beams 12, the end beams 14, and the connecting beams 13 are all square steel pipes. The joints of the side beams 11, the cross beams 12, the end beams 14, and the connecting beams 13 are connected by welding, and the overall weight of the support frame 1 is relatively light. However...

Abstract

The invention provides a welding fixture for an eight-axis bogie frame of an electric locomotive. The welding fixture comprises a support frame; the support frame comprises two side beams, two cross beams between the side beams, end beams at the two ends of the side beams and connecting bases on the end beams; the two cross beams, the side beams arranged between the cross beams and a connecting beam located between the two cross beams form a middle positioning region; the end beams on the same sides of the side beams, the cross beams and the side beams between the end beams and the cross beams form end positioning regions; the middle positioning region comprises a positioner arranged on the connecting beam, first mounting bases arranged on the side beams and push-on mechanisms arranged on the first mounting bases; each end positioning region comprises three second mounting bases arranged on the corresponding side beam, hold-down mechanisms arranged on the second mounting bases and positioners arranged on the second mounting bases; positioners are arranged on the side beams at the joints of the side beams and the cross beams. The welding fixture for the eight-axis bogie frame of the electric locomotive is capable of quickly and accurately positioning plates by means of the cooperation of the positioners, the push-on mechanisms, the hold-down mechanism, the end positioning mechanisms and the end anti-thrust mechanisms.

Description

technical field [0001] The invention relates to a welding tool, in particular to a welding tool fixture for an eight-axle bogie frame of an electric locomotive. Background technique [0002] The bogie frame of an electric locomotive is welded by multiple metal plates. The welding position and welding quality of each part directly affect the quality of the bogie frame. Regarding the safety of the locomotive operation, the bogie frame requires special attention when welding. carefully. The premise of the welding quality of the bogie frame is whether the relative position of the plate and the plate meets the design requirements before welding. However, the existing technology lacks positioning tooling specially used for bogie frames, which leads to inaccurate relative positions between plates and affects welding quality; moreover, it takes a long time to adjust and fix the position between plates, which greatly reduces the working efficiency. Low. Contents of the invention ...
