Problems solved by technology

There are a lot of inspection personnel, and the labor cost is large, which increases the manufacturing cost of the product
Manually checking the size requires the cooperation of two people, and factors such as the angle of the tape measure may affect the accuracy of the measurement
In addition, manual inspection is greatly affected by the inspector's skills, mood, and physical fitness, resulting in unstable inspection dimensions
[0004] Since the underframe of the railway freight car is currently inspected manually and the amount of inspection is large, it is generally carried out by random inspection, and it is difficult to conduct a 100% full inspection
This method of manual inspection and batch random inspection cannot guarantee that the key dimensions of each carriage chassis meet the requirements. This method of random inspection makes the phenomenon of unqualified quality frequently appear
[0005] Furthermore, since the detection system needs to give feedback on the measurement results, it cooperates with the adjustment system (the adjustment system includes two adjustment gantry and multiple adjustment cylinders, the adjustment cylinder includes the adjustment cylinder on the gantry, and the arrangement under the chassis The 4 upper cylinders for correcting the side beams that can move longitudinally, and the 2 upper cylinders for correcting the center beam. The adjustment cylinders are used to correct deflection, warping and other deformations by pushing them up. Manual inspection cannot be done automatically. To generate a test report, it takes a lot of manpower to fill in the test report

Embodiment 1

[0070] The embodiment of the present invention provides a three-dimensional detection system 100 for the underframe of the carriage, which is used for automatic high-precision detection of the underframe of the carriage. The detection system 100 can be installed independently of the production line for the processing of the underframe for the carriage, and can also be installed in the production line for the processing of the underframe. On the adjustment and correction station, in order to improve the production and processing efficiency, this embodiment adopts the second solution, that is, the detection station and the adjustment and correction station are combined into one. see figure 1 , the detection system 100 includes a detection gantry 10, a gantry guide rail 20, a gantry traveling device 30, a detection device 40, a center disk positioning device 50 and a console (not shown in the figure), and the structure of each component is described in detail below:

[0071] see ...

Embodiment 2

[0092] Based on the same inventive concept, this embodiment provides an online adjustment and alignment system for the underframe of the carriage, which is composed of the existing adjustment and alignment system 200 through structural improvement and combined with the three-dimensional inspection system 100 for the underframe of the carriage in the first embodiment above.

[0093] see Figure 5A , Figure 5B with Figure 5C , The adjustment and straightening system 200 includes the adjustment and straightening gantry 70 and the adjustment and straightening oil cylinder 80, and the adjustment and straightening gantry 70 is provided with two, each one at the front and rear in the longitudinal direction. Adjustment and correction oil cylinder 80 is provided with a plurality of, specific number depends on the point to be adjusted and correction of underframe, and adjustment and correction oil cylinder 80 can be installed on adjustment and correction gantry 70, also can be instal...

Embodiment 3

[0097] Based on the same inventive concept, this embodiment provides a three-dimensional inspection method for a carriage underframe, which is implemented based on the three-dimensional inspection system 100 for a carriage underframe in the above-mentioned embodiment 1, and specifically includes the following steps:

[0098] (1) The carriage underframe is transported to the detection station 300 , and the carriage underframe is placed on the center plate positioning device 50 , and the center plate of the carriage underframe rests on the center plate positioning surface 52 .

[0099] Specifically, the transport vehicle 60 is used to transport the underframe from the previous station to the detection station 300, and the transport vehicle 60 automatically stops when it is in place. At this time, the machine vision device 55 can be started first, and the bottom frame can be judged through the image taken by the machine vision device 55. Whether the frame center plate is in the sh...

Abstract

The invention discloses a three-dimensional detection system for a carriage underframe, an online adjustment system and a method. A detection gantry is provided with a three-dimensional detection and detection system in the area between the adjustment and correction system and the carriage underframe. The three-dimensional detection system includes a detection gantry and a gantry guide rail. , gantry walking device, detection device, center plate positioning device and console, the detection device is driven by the detection gantry and its accessories, so as to traverse the entire carriage chassis, and measure the external dimension characteristics of the carriage chassis by means of upper detection; The disk positioning device can not only realize the positioning of the center disk of the carriage chassis, but also detect the relevant characteristics of the center disk. The detection data is imported into the console, and the detection report is automatically generated by the console. Through the three-dimensional detection system of the carriage underframe, automatic and high-precision detection of the three-dimensional size of the carriage underframe can be carried out, and the results can be fed back to the adjustment and correction system in real time to guide the work of the adjustment and correction system.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle performance testing, and in particular relates to a three-dimensional detection system for a carriage underframe, an online adjustment system and a method. Background technique [0002] The carriage chassis is the critical large component of a railway freight car body and tends to carry most of the body and cargo loads. In the process of manufacturing railway wagons or transporting goods, the underframe is often deformed due to stress accumulation or long-term load in the production process, and the geometric parameters of the underframe are prone to change. Therefore, no matter in the new construction of railway wagons or in the repair process, the typical characteristics of the underframe, namely the length of the underframe, the width of the underframe, the diagonal difference of the underframe, the fixed distance of the center plate, the transverse clearance of the center plate, the dista...
