Problems solved by technology

[0017] Because the position of the support seat of the side frame is not correct (not in the horizontal or vertical position), the existing technology is adjusting the top of the fitter to ensure that the side frame and the platform remain parallel and vertical, measure the center of the retaining ring ring, and measure the two retaining rings of the same support seat. In the process of measuring the distance from the side frame pedestal to the retaining ring, measuring the included angle β, etc., the operation is complicated, it is difficult to select the measurement position, the positioning is inaccurate, prone to deviation, the accuracy is not high and it takes a long time
Disadvantages of the existing technology: (1) low marking accuracy; (2) long time-consuming and low work efficiency; (3) highly affected by the technical level of marking workers

Embodiment Construction

[0065] (1) Measure the distance H1 from the bearing surface of the side frame bearing saddle to the platform.

[0066] produced two such Figure 4 , 5 The stand shown. The two supports have the same height, the upper and lower planes are parallel, and the upper and lower planes are perpendicular to the sides. Put the side frame working position (vertical position) on the support, such as Image 6 shown. At this time, the height of the support is the vertical distance H1 between the bearing surface of the side frame bearing saddle and the platform.

[0067] (2) Measure the distance H from the center of the side frame support seat to the bearing surface of the bearing saddle.

[0068] produced as Figure 7 , Figure 8 Centerline positioning blocks shown. Since the inner hole size of the retaining ring is Φd±0.5mm, in order to ensure the close contact with the retaining ring when making the centerline positioning block, the d dimension is a series size with a taper of 1:1...

Abstract

The invention belongs to the technical field of vehicle measurement of railway locomotives and particularly relates to a method for scribing and measuring a side frame. The purpose of the method for scribing and measuring the side frame is to improve scribing efficiency and scribing precision of a central line. The method for scribing and measuring the side frame comprises the steps of: measuring a distance from a bearing surface of a load-bearing saddle of the side frame to a platform; measuring distances from centers of support bases of the side frame to the bearing surface of the load-bearing saddle; leading the center of a retaining ring to the support bases by wires; measuring the position of vertical central point A of the retaining ring; measuring distances from a guide frame to the support bases, a distance between the two support bases and distances from the support bases of the side frame to the central line of the side frame; and measuring included angles between the support bases and a longitudinal centre line of the side frame. According to the method for scribing and measuring the side frame, disclosed by the invention, the scribing efficiency and scribing precision of the central line are improved, and the scribing precision difference caused by different scribing engineering levels of skilled workers is eliminated.

Description

technical field [0001] The invention belongs to the technical field of railway rolling stock measurement, and in particular relates to a method for measuring a side frame scribing line. Background technique [0002] With the acceleration of railway freight cars, new technologies are widely used in freight car bogies to meet the requirements of the new situation; at present, more than 500,000 railway freight cars use cross-bracing bogies, and more than 2 million cross-bracing device side frames are in use. It is stipulated in the technical conditions of the bogie of the cross-bracing device that the first piece of the side frame must be checked by a fitter every day to ensure that the side frame is in good condition and meets the requirements, and the safety and reliability of the railway freight car is guaranteed. [0003] For technical requirements of side frame marking, see figure 1 . [0004] 1. The distance H from the center of the support seat (retaining ring) to the ...
