Problems solved by technology
[0003] In order to overcome the disadvantages of waste of time and low processing efficiency due to the need for secondary clamping in the processing of the existing side frame outer pedestal, the present invention provides a processing technology and tooling for the side frame outer pedestal of railway wagons. The outer guide frame of the side frame only needs to be clamped once, which saves a lot of auxiliary time and greatly improves the processing efficiency

Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing:
[0019] Depend on Figure 1 to Figure 3 As shown, due to figure 1 , figure 2 Both are left-right symmetrical structures, therefore, only the structure of the left half is given, and the right half is omitted. A process for processing the outer pedestal of a side frame of a railway freight car, characterized in that it comprises the following steps:
[0020] a. Line marking: use the crane to hoist the side frame onto the platform, support it with a jack, and use a square to check whether the side frame is vertical. According to the flatness of the spring bearing surface 24 on the workpiece every 100mm is not greater than 1mm and the upper edge of the bearing surface 21 Level the side frame; find out the general center of the side frame, measure the center of the pedestal from the center to both sides, and then use a scribing board to mark the line;
[0021] b. Positionin...

The invention relates to a processing technology and a tool for an outer guide frame of a side frame of a rail wagon, which mainly solves the problems that the outer guide frame of the existing side frame is wasteful in time and low in processing efficiency due to the need of second clamping in processing. The technology comprises the following steps: a. scribing; b. locating: one end of the side frame is located by a bearing platform top supporting bolt (14), and the other end of the side frame is located by a splay surface supporting bolt (15); c. clamping: two ends of the side frame are clamped by pressure plates (12), and an upper bottom plate (5) and a lower bottom plate (4) are clamped by an air clamp (1); d. milling of one side of the outer guide frame; e. turning: the upper bottom plate (5) is rotated by 180 degrees, and then a locating pin (16) is inserted into a locating sleeve (2) at the other side to ensure 180-degree rotation angle; f. milling of the other side of the outer guide frame; and g. checking. By adopting the technology and tool for processing, the outer guide frame of the side frame can be clamped only by one step, a great deal of time for assisting can be saved, and the processing efficiency can be greatly enhanced.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a processing technology and tooling for the outer pedestal of the side frame of a railway freight car. Background technique [0002] The bogie is an important part of the railway freight car, which determines the safety and reliability of the operation. The side frame is the main force-bearing part of the bogie, which plays the role of bearing and transmitting various forces and loads. Driving safety plays a vital role. As the demand for railway wagons increases year by year in recent years, and the variety of national railways and export wagons increases, effectively improving the processing quality and efficiency of side frames is a key problem that needs to be solved urgently in current production. Side frame outer pedestal side frame processing is an important process. At present, the side frame outer pedestal is processed by X2010C gantry milling machine. Turn over and process the...
