[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0025] like Figure 1 As shown, an embodiment of the present invention provides a structural schematic diagram of an automobile parts detection tool. The automobile parts detection tool has modular design, quick disassembly and assembly, plug-and-play, intelligent judgment and AGV automatic guided vehicle.

[0026] Figure 1 Combination Figure 2 to Figure 8 The automobile parts detection tool comprises a parts base support bracket 1, which is preferably formed by welding a plurality of aluminum alloy profiles, and the wall thickness of the parts base support bracket 1 is 6 mm.

[0027] The part base support bracket 1 is installed with multiple spare module mounting frames 5, and multiple part positioning modules 2, multiple clamping modules 3 with electromagnet function, multiple detection modules 4 and multiple ID recognition function modules 6 are installed on the part base support bracket 1; multiple part positioning modules 2, multiple clamping modules 3 with electromagnet function and multiple detection modules 4 are also installed on the spare module mounting frame 5; an AGV automatic guided vehicle 7 is installed on the bottom foot pad of the part base support bracket 1.

[0028] Multiple part positioning modules 2, multiple clamping modules 3 with electromagnet function, and multiple detection modules 4 are all installed on the part base support bracket 1 or the spare module mounting bracket 5 through positioning pins. The positioning pins are preferably electromagnet adsorption fastening components, which are used to adsorb the part positioning module 2, the clamping module 3 with electromagnet function, and the detection module 4 on the part base support bracket 1.

[0029] On this inspection fixture, in order to ensure the consistency of the accuracy of each module after installation, position sensors are provided at the installation positions of the part positioning module 2, the clamping module 3 with electromagnet function, and the detection module 4. Each position sensor needs to be integrated with an ID recognition function module 6. When each module is installed, the position sensor can detect whether the positioning status is correct, otherwise it is necessary to check the status of the position of each module. The ID recognition function module 6 has the function of judging the installation position status of each module and has an integrated system that outputs signals to the detection tool to judge whether the detection module to be replaced is correct.

[0030] When the AGV automatic guided vehicle 7 is in use, the product identification code to be tested is input, and the testing tool is automatically transported to a fixed position in the measuring room, or the testing tool is automatically transported to a fixed position in the inspection tool warehouse.

[0031] The clamping module 3 with electromagnet function is the chuck of the reference block, and the detection module 4 is a detection simulation block for the key control part of the part size. The detection simulation block is a special detection block for the part type; the ID recognition function module 6 collects the transmitted signal and compares the position of the detection module 4 in the integrated system of the detection tool to determine whether the detection module 4 used is correct; the integrated system of the detection tool imports different installation points of different parts and assigns different ID numbers. After installation, it automatically identifies whether it is the detection module of the part to be detected by the ID number.

[0032] Among stamped parts, the same positioning strategy can be adopted for the same parts. Therefore, the same parts can adopt the same part base support bracket 2. The part positioning module 2, the clamping module 3 with electromagnet function, and the detection module 4 required for the detection of each part are installed on the part base support bracket 2. Each module is positioned by a positioning pin, and the electromagnet in the standard block is adsorbed and fastened. The position sensor detects whether each module is installed in place; the corresponding product ID is read through the production instruction, and the corresponding product detection digital model is called.

[0033] Since the testing tools are generally kept in a measuring room with a constant temperature and humidity, and the inspection fixtures are generally in the inspection fixture warehouse, the inspection fixtures need to be transported to the measuring room during testing. Traditional transportation uses a crane or a forklift, which requires the installation of a crane in the measuring room or space to ensure the movement of the forklift, which wastes costs to a certain extent and has high operating and maintenance costs. The inspection fixture of the utility model is integrated with an AGV automatic guided vehicle 7. When in use, the product identification code to be tested is input, and the AGV automatic guided vehicle 7 can automatically transport the product to the measuring room.

[0034] Each detection module of the same type of parts of the next model can be prepared on the spare module mounting frame 5 to achieve N+1 production mode. A set of common positioning modules 2, clamping modules 3 and detection modules 4 of the same type of parts of other models are provided on the basic support bracket 2. The positioning pins of the part positioning module 2 can also be fixed to ensure the stability of the positioning function.

[0035] The beneficial effects brought by the inspection tool for automobile parts are: saving the cost of developing inspection tools; saving floor space; improving inspection work efficiency; reducing the labor intensity of inspection; convenience of operation, including product placement and inspection, operation and transportation of clamps, etc.; constant and accurate positioning reference to ensure maximum repeatability and reproducibility; having and being able to realize the reference for inspection tool processing and inspection: processing reference and measurement reference, which can be used for later modification and regular verification of inspection tools; intelligent transportation, realizing point-to-point transportation without borrowing other transportation equipment.

[0036] The detection tool for automobile parts is designed with a common basic support bracket for parts of the same type using the same positioning strategy, which reduces the investment in the support bracket and the floor space of the workshop; a set of common part positioning modules, different clamping modules and detection modules are developed for different parts; the support detection bracket often has a set of module structures of each set of parts, and the spare module mounting frame reserves the position of each module structure of another set of parts; when it is necessary to replace the module with a spare vehicle model, the integrated system is used in the inspection fixture library to automatically load and unload according to the ID instruction; when installing each module, the pin of the standard block is inserted into the standard hole of the support bracket, and the power of the electromagnet is turned on. The electromagnet works to adsorb the module on the basic support bracket of the part, and the position sensor will detect whether the installation is in place. If it is not in place, the alarm will sound and readjust it until it is in place.

[0037] After loading and unloading, the inspection tool is taken out of the inspection fixture warehouse, and according to the instructions of the AGV automatic guided vehicle, it is automatically transported to the fixed inspection position in the inspection room, stopped and fixed, and the ID recognition function module is turned on. The ID signal detected by the integrated system retrieves the data and program of the part. After preparation, the part is placed on the inspection fixture, and the inspection-related program is started; after the inspection is completed, the program returns to its position, the ID recognition function module is disconnected, and an instruction is sent to the AGV automatic guided vehicle to transport it back to the inspection fixture warehouse. The inspection fixture returns to the inspection fixture warehouse according to the specified route.

[0038] The technical innovations of the inspection tool for automotive parts are as follows: (1) The same positioning strategy is adopted for the development of inspection tools based on the same type of parts, and the inspection tools are modularly designed; (2) The inspection tool design is developed in the N+1 mode, with a shared support bracket, and only the modules of the same parts need to be developed, saving development costs; (3) Each module adopts a standardized structure, which is easy to disassemble and assemble, improving work efficiency and reducing labor intensity; (4) Each module includes an installation detection alarm system; (5) An integrated ID system is used to achieve intelligent identification and intelligent detection; (6) AGV automatic guided vehicles realize intelligent transportation, saving the work of borrowing other equipment for transportation and improving work efficiency;

[0039] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
