Indoor centering and positioning device suitable for trains with different inner widths

Abstract

The invention discloses a centering positioning device suitable for vehicle indoors with different internal widths, and belongs to the field of positioning devices of central planes of the indoor transverse width of railway vehicles. The centering positioning device comprises a four-wheel trolley, a door-shaped frame, two sets of vertical slide rail mechanisms, a vertical lifting screw rod mechanism and a wide-direction central plane centering system, wherein the wide-direction central plane centering system comprises a vertical lifting platform and a horizontal centering mechanism, and the door-shaped frame comprises a horizontal cross beam and two vertical stand columns which are integrally formed. According to the centering positioning device, the problems that the operation process iscomplex, the workload is large, the surveying and mapping efficiency is low and the universality is low due to the fact that a traditional surveying and mapping method used the modes of measuring by adrawing ruler and marking and scribing by a mark pen to determine the center plane in the width direction of the vehicle indoor are overcome, so that deviation errors caused by measuring by the ruleand scribing on the center of all parts of a vehicle are reduced, the quality problems that the center is inaccurate and the position is offset existing in the aspect of vehicle body manufacturing areeffectively solved, and size precision, the assembling quality and the working efficiency in the overall assembly construction process of the urban rail vehicle body are improved.

Description

technical field [0001] The invention belongs to the field of positioning devices for the central plane of the lateral width of a rail vehicle interior, and in particular relates to a centering positioning device for a train room with different inner widths. Background technique [0002] The car body of a rail vehicle is relatively large, and contains many symmetrical structures such as door systems and windows. When manufacturing a train car body, the above-mentioned many symmetrical structures need to comply with the theoretical size requirements of the drawing. The central plane is strictly symmetrical. [0003] However, the central plane in the width direction of the car body compartment is only a theoretical virtual plane, and there is no corresponding special positioning tool in the actual production process. In order to determine the actual position of the center plane, it is often necessary to use traditional surveying and mapping methods such as ruler measurement, m...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the existing traditional surveying and mapping method of determining the center plane in the width direction of the vehicle by using ruler measurement, marker pen marking and scribing, the work is cumbersome and complicated, and there are many tools such as tape measure, ink line, weight, marker pen and so on. Large amount, low surveying and mapping efficiency, and poor versatility, and the current lack of a special positioning tool for the center plane of the vehicle interior width direction that is suitable for different width positions such as the left and right door systems, left and right side walls, and left and right windows. , the present invention provides a centering and positioning device suitable for train interiors with different inner widths
