Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0024] like Figure 1 and Figure 2 As shown, an intelligent measurement and matching platform for rear block of railway freight car bearings includes: a rear block incoming material warehouse 1, a manual measurement platform 2, a human-machine interaction terminal 3, a contact measurement system 4, a three-dimensional warehouse to be matched 5, a printer 6, a rear block storage area 7, an electrical cabinet 8, a precision ground rail 9, an industrial robot 10, and a gripping tool 11.

[0025] The backstop material warehouse 1, precision ground rail 9 and electrical cabinet 8 are arranged on one side of the overall work area, and the contact measurement system 4, the three-dimensional warehouse to be selected 5, the inkjet printer 6 and the backstop storage area 7 are arranged on the other side of the overall work area. The backstop material warehouse 1 and the three-dimensional warehouse to be selected 5 are arranged on different sides to avoid interference between the loading position and the storage position. The backstop material warehouse 1 is adjacent to the contact measurement system 4, and the industrial robot 10 can achieve the detection purpose with the minimum path.

[0026] A manual measuring platform 2 is arranged on one side of the rear material storage 1, a human-machine interaction terminal 3 is arranged on one side of the manual measuring platform 2, an industrial robot 10 is arranged on the precision ground rail 9, and a gripping tool 11 is arranged on the industrial robot 10.

[0027] As a preferred embodiment of the present invention, the industrial robot 10 has a fingertip motion range radiation contact measurement system 4 and a rear block incoming material warehouse 1. The position of the rear block incoming material warehouse 1 is convenient for the industrial robot 10 to grasp. The industrial robot 10 moves its position through the precision ground rail 9, and can complete the grasping and handling operations of the entire matching task.

[0028] As a preferred embodiment of the present invention, a measurement system detection area is formed below the contact measurement system 4 .

[0029] As a preferred embodiment of the present invention, the rear-block incoming material warehouse 1 and the three-dimensional warehouse to be selected 5 are multi-layer structures.

[0030] As a preferred embodiment of the present invention, a plurality of storage warehouse positioning card blocks are arranged on the rear-block incoming material warehouse 1, the optional three-dimensional warehouse 5 and the rear-block storage area 7, and an infrared sensor is arranged inside the storage warehouse positioning card block. The infrared sensor is used to identify whether there are parts in the warehouse, transmit them to the human-computer interaction terminal, and check the storage status of the warehouse in real time.

[0031] As a preferred embodiment of the present invention, a voice control module is provided inside the human-computer interaction terminal 3, and the voice control module can recognize voice to control the movement of the platform.

[0032] As a preferred embodiment of the present invention, a database is provided inside the human-computer interaction terminal 3, and the database can store matching situation data.

[0033] As a preferred embodiment of the present invention, LED lights are provided on several storage locations of the rear-block incoming material warehouse 1 and the three-dimensional warehouse to be selected 5.

[0034] As a preferred embodiment of the present invention, the number of storage locations in the stereoscopic warehouse 5 to be selected is 200. 30 wheel sets of a vehicle section need to be selected for 60 rear gears per day. The selection results can be stored in the database for later quality management, and the working conditions and efficiency of the equipment can be viewed as a whole each month.

[0035] The operation process of this platform:

[0036] 1) Parts grabbing: When the bearing backstop parts to be tested are sent to the backstop incoming material warehouse 1, the industrial robot 10 and the clamping tooling 11 are first used to move the bearing backstop parts to be tested to the detection area of ​​the contact measurement system 4. During the grabbing and handling process, scratches and bumps on the surface of the parts should be avoided.

[0037] 2) Detection of the size of the bearing back stop part: Use the contact measurement system 4 to complete the measurement of the inner hole size of the part; the detection equipment has the ability to detect the shape accuracy of the detection hole, and can match the shape characteristics of the shaft and hole parts; the detection module can be used independently as a separate module to avoid surface damage to the part during the detection process.

[0038] 3) Intelligent voice control: When parts are being inspected, it is inconvenient for workers to operate computers due to the special working environment. A voice control module is introduced during the selection of the bearing backstop. The voice control module improves the convenience of maintenance while ensuring safe operation of the equipment.

[0039] 4) LED lights distinguish the backstop levels: The LED lights on the backstop incoming material warehouse 1 and the optional three-dimensional warehouse 5 distinguish the different levels of bearing backstops. The LED lights have seven colors, which represent seven levels to facilitate workers to check the storage status of the backstops for visual management.

[0040] 5) Differentiated management and on-site management of rear guards of different grades: Different grades of rear guards are marked with different colors of LED lights to facilitate subsequent quality management; the size information is sprayed on the outer ring of the rear guard by the inkjet printer (6) to achieve on-site visual management of rear guard measurement and selection quality.

[0041] 6) Database provides data support: The database in the human-computer interaction terminal 3 stores all process information during the rear gear selection process, and provides data support for the production organization of the later workshop management level based on the database.

[0042] The invention is used to detect the inner diameter size and shape position size of multiple groups of parts with matching relationship, such as the inner diameter of multiple groups of railway freight car bearing rear stop parts and the relative position and shape accuracy of multiple groups of coaxial holes.

[0043] For a group of parts with matching relationships (60 shaft parts and 200 hole parts are set as a group, which can be adjusted appropriately), the parts in the group are automatically matched and combined based on the principle of achieving the maximum number of matched parts, provided that the matching clearance requirements are met. For assemblies with multiple groups of coaxial holes and shaft parts that have matching relationships (i.e., a shaft part has matching relationships with multiple hole parts), an assembly combination scheme for a shaft part and multiple hole parts can be automatically provided based on the over-constraint problem caused by multiple hole parts.

[0044] When matching shaft and hole parts, the principle of traceability is followed to ensure that the matching of shaft and hole parts is reasonable and correct. In addition, the part number corresponds to the data to achieve traceability; identification of part coding or QR code: identifying part code information to facilitate binding of its test data results; data traceability and storage: for the tested data, it can be bound to the corresponding number to achieve traceability, storage and query functions. The matching method of the matching system can automatically complete the matching information management of the bearing back block, and there is no need to record the specific matching information of the back block. Compared with the traditional manual matching method of the bearing back block, it realizes automatic matching and is more efficient.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can still adjust the technical solutions described in the above embodiments or replace some of the technical features by equivalents. Therefore, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
