[0025] The rear retainer incoming material warehouse 1, the precision ground rail 9, and the electrical cabinet 8 are sequentially arranged on one side of the overall working area. The contact measurement system 4, the to-be-matched three-dimensional warehouse 5, the coding machine 6, and the rear retainer storage area 7 are sequentially arranged on the other side of the overall working area. The rear retainer incoming material warehouse 1 and the to-be-matched three-dimensional warehouse 5 are arranged on different sides, avoiding interference between the loading position and the storage position. The rear retainer incoming material warehouse 1 is adjacent to the contact measurement system 4, and the industrial robot 10 can reach the detection purpose with the shortest path.
[0026] An artificial measurement platform 2 is arranged on one side of the rear retainer incoming material warehouse 1. A human-machine interaction terminal 3 is arranged on one side of the artificial measurement platform 2. An industrial robot 10 is arranged on the precision ground rail 9, and a clamping tooling 11 is arranged on the industrial robot 10.
[0027] As a preferred embodiment of the present utility model, the fingertip movement range of the industrial robot 10 radiates the contact measurement system 4 and the rear retainer incoming material warehouse 1. The position of the rear retainer 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 utility model, a measurement system detection area is formed below the contact measurement system 4.
[0029] As a preferred embodiment of the present utility model, the rear retainer incoming material warehouse 1 and the to-be-matched three-dimensional warehouse 5 are multi-layer structures.
[0030] As a preferred embodiment of the utility model, 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 utility model, LED lights are provided on several storage locations of the rear-block incoming material storage 1 and the three-dimensional storage 5 to be selected.
[0034] As a preferred embodiment of the utility model, the number of storage locations of 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 light rear retainer grade differentiation: The LED lights on the incoming material warehouse 1 for rear retainers and the three-dimensional warehouse 5 for waiting to be selected and matched differentiate rear retainers of different grades. The LED lights have seven colors, and using seven colors to represent seven grades facilitates workers to view the storage situation of rear retainers, so as to facilitate visual management.
[0040] 5) Differentiated management and on-site management of rear retainers of different grades: Different grades of rear retainers are color-coded through different colors of LED lights for later quality management; through automatic coding by the inkjet printer (6), size information is sprayed on the outer ring of the rear retainer to achieve on-site visual management of rear retainer measurement and matching quality.
[0041] 6) The database provides data support: The database in the human-computer interaction terminal 3 stores all process information during the matching process of rear retainers, and provides data support for the production organization of the later workshop management level according to the database.
[0042] The utility model is used to detect the inner diameter dimensions and shape and position dimensions of multiple groups of parts with mating relationships in parts, such as the inner diameters of multiple groups of rear retainer parts of railway freight car bearings and the relative positions and shape accuracies of multiple groups of coaxial holes.
[0043] For a group of parts pairs with a pairing relationship (assuming 60 shaft parts and 200 hole parts as a group, which can be appropriately adjusted), on the premise of meeting the requirements of the fit clearance, with the principle of maximizing the number of completed paired parts, the parts within the group are automatically paired and combined. For multiple groups of components where coaxial holes and shaft parts have a mating relationship (that is, one shaft part has a mating relationship with multiple hole parts), according to the overconstraint problem caused by multiple hole parts, an assembly combination plan for one shaft part and multiple hole parts can be automatically provided.
[0044] When matching shaft-hole parts, ensure the reasonable correctness of shaft-hole part matching according to the principle of traceability. In addition, the part numbers correspond to the data, enabling traceability; identification of part codes or two-dimensional codes: Identify part code information to facilitate binding of its test data results; data traceability and storage: For the data that has been tested, it can be data-bound with the corresponding number to achieve traceability, storage, and query functions. The matching method of the matching system can automatically complete the management of the matching information of the rear retainer of the bearing, and there is no need to still record the specific matching information of the rear retainer. Compared with the traditional manual matching method of the rear retainer of the bearing, it realizes automatic matching and has higher efficiency.
[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Those skilled in the art can still adjust the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Therefore, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and variations.
