Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical equipment, and particularly to a positioning device for a fixing plate of an angular bearing seat of a large vehicle frame. Background Art

[0002] A large vehicle frame is generally supported by four wheel sets. The wheel sets mostly adopt the form of angular bearing seats, that is, one angular bearing seat is installed on each side of the left and right of each wheel set. The fixing plate on the vehicle frame that cooperates with the angular bearing seat is welded to the vehicle frame by two steel plates that are perpendicular to each other at 90°. After machining the two sides and the outer end face of the steel plates, they are used to cooperate with the angular bearing seat.

[0003] In order to ensure the dimensional and positional accuracy of the fixing plate of the angular bearing seat on the vehicle frame, one method is to machine after welding the fixing plate to the vehicle frame, but this operation requires a large machining machine tool. Another method is to machine the fixing plate separately and then assemble and weld it to the vehicle frame. For manufacturers without large machining machine tools, only the second manufacturing process can be adopted. When welding the fixing plate to the vehicle frame after machining, usually the wheels and the angular bearing seats are assembled first, and then the relative positions of the fixing plate and the angular bearing seats are adjusted with the wheels as the reference, and then welded.

[0004] When using the method of assembling the wheel sets and adjusting the fixing plate, the angular bearing seat is prone to swing on the shaft and is not parallel to the wheels. The weight and external dimensions of the wheel sets are large, it is difficult to adjust the parallelism and center distance of the angular bearing seats, the production efficiency is low, the labor intensity is high, and the installation position accuracy is not high.

[0005] In view of this, the prior art should be improved to solve the above-mentioned technical problems existing in the prior art. Summary of the Invention

[0027] To solve the problems in the prior art, the present invention proposes the following solutions:

[0028] Designed according to the assembly structure dimensions of the angular bearing seats on both sides of the wheel set and the frame 1, the main body is composed of a support 2 and a fixing plate, and is used to replace the angular bearing seats on both sides of the wheel set.

[0029] Machine the end face, side face and mating holes for the fixed plate and the angular bearing block, leaving a machining allowance for the thickness. After determining the position of the horizontal fixed plate 4, machine the thickness of the horizontal fixed plate 4. The horizontal fixed plate 4 is bolted to the bottom of the support 2 and then placed on the vehicle frame 1. After adjusting the position of the side face of the support 2, machine the thickness of the side fixed plate 3.

[0030] Bolt the side fixed plate 3 to the side face of the support 2, then adjust the installation position of the side face of the support 2 and the vehicle frame 1. Then, spot-weld the fixed plate and the vehicle frame 1 firmly. After removing the support 2 from the fixed plate, weld the fixed plate and the vehicle frame 1. Finally, drill the mating holes 15 for the vehicle frame 1 and the bearing block according to the fixed plate.

[0031] The present invention provides a positioning device for the fixed plate of the angular bearing block of a large vehicle frame 1, as Figures 1-3 shown. The positioning device includes a support 2, a horizontal fixed plate 4 and a side fixed plate 3.

[0032] The support 2 is arranged at the wheel position of the vehicle frame 1 and includes a horizontal fixed plate mounting surface 5 and a side fixed plate mounting surface 6.

[0035] In order to ensure the correct position during the installation process, the wheel center line 9, the longitudinal center line 10 of the vehicle frame and the horizontal center line 11 of the wheel axle are marked in advance.

[0036] The widths of the lower stop 12 of the support and the side stop 13 are equal, and are equal to the side distances of the side fixed plate 3 and the horizontal fixed plate 4 after machining on the vehicle frame 1, so as to ensure that the side fixed plate 3 and the horizontal fixed plate 4 can be just inserted into the side stop 13 and the lower stop 12 of the support respectively. The height of the side fixed plate mounting surface 6 on the support 2 exceeds the outer plane of the vehicle frame 1.
