Embodiment 1

[0051] The present invention includes the following steps:

[0052] S1. On the left and right sides of the load-bearing spring, there are multiple groups of through-beam fiber optic sensor receiving ends and through-beam fiber optic sensor transmitting ends; multiple groups of through-beam fiber optic sensors are fixed on the fixture as a whole, the fixture A manipulator is connected by a flange, and a T-hook head for picking and placing the load-bearing spring is also provided on the fixture. The vertical distance between the center of the T-hook head and the through-beam optical fiber sensor remains unchanged; adjacent through-beam types The spacing of the fiber optic sensors is the same.

[0053] S2. The output switch signal of the through-beam optical fiber sensor is "True" and "False". During the positioning process, the output is False when the receiving end and the transmitting end are set to be unobstructed, otherwise it is True, and the corresponding I / 0 signal is : "1" m...

Embodiment 2

[0059] By limiting the distance W between the uppermost through-beam fiber optic sensor and the lowermost through-beam fiber optic sensor:

[0060] max{D spring , L Spring clearance } spring +2·L Spring clearance , L Spring clearance +2·D spring }, where D spring Indicates the wire diameter of the loaded spring. It is ensured that the relative positional relationship between the through-beam fiber optic sensor and the spring will only appear as shown below. figure 1 With attached figure 2 Of the two cases, attached figure 1 With attached figure 2 The corresponding I / 0 are as attached image 3 With attached Figure 4 Shown. Attached image 3 With attached Figure 4 The "1" in "True" means that the transmitting end and the output end are blocked, and there is a load-bearing spring between the pair of through-beam optical fiber sensors; "0" means "False" that the transmitting end and the output end are not blocked. There is no spring blocking between the through-beam fiber...

Abstract

The invention discloses a bogie bearing spring locating method, and belongs to the technical field of bogie disassembly. The bogie bearing spring locating method is used for solving the problems thata traditional bearing spring is inaccurate in location and low in location speed and comprises the following steps of: step 1. arranging receiving end and transmitting ends of multiple groups of opposite type optical fiber sensors at the left side and right side of a bearing spring; step 2. setting output switching value signals of the opposed optical fiber sensors as True of False; step 3. defining the distance between the center of a 'T-shaped hook head' of a robot clamp and a group of opposite type optical fiber sensors on the top as a known installing distance D2; step 4. If detecting thegap of the bearing spring, carrying out robot offset distance calculation; step 5. If detecting the outer edge of the bearing spring, carrying out robot offset distance calculation; and step 6. movingthe center point of the 'T-shaped hook head' of the robot clamp to the middle of the spring gap. The method has the advantages of fast and accurate location.

Description

Technical field [0001] The invention relates to the technical field of bogie disassembly, and more specifically to a method for positioning a bogie bearing spring. Background technique [0002] The bogie is one of the most important components in the structure of rail vehicles, and various parameters of the bogie also directly determine the stability of the vehicle and the ride comfort of the vehicle. A load-bearing spring is arranged between the bolster and the side frame. During the overhaul of the bogie, the structure needs to be disassembled. The load-bearing spring is mainly removed manually. The type of the bogie is different. There are three rows of, middle and inner, and there are differences in quantity and model. A load-bearing spring includes an inner spring and an outer spring, and its total mass is 14-16kg. The daily work intensity of workers is very high. [0003] However, the existing springs used by manipulators to grasp and place the springs are positioned by huma...
