Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an inspection tool for an active air intake grille frame of an automobile. Background Technology

[0002] As the core load-bearing component of the automotive active grille shutter, the AGS frame assembly's dimensions, mounting hole tolerances, and matching accuracy directly affect the grille's opening and closing function and the vehicle's airtightness. Currently, the industry primarily uses coordinate measuring machines (CMMs) to inspect AGS frame assemblies. While CMMs offer high inspection accuracy, they suffer from low inspection efficiency (a single inspection typically takes over 30 minutes), complex operation, high equipment costs, and the inability to simulate actual assembly conditions. This makes it difficult to meet the needs of rapid process monitoring of a large number of AGS frame assemblies on the production line.

[0003] Therefore, it is necessary to design an active grille frame fixture for automobiles to improve the above-mentioned problems. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides an inspection tool for an active air intake grille frame of an automobile. This tool can perform rapid, accurate, and comprehensive inspection, quickly determining whether the parts are qualified and their compatibility with environmental components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automotive active air intake grille frame inspection fixture includes a cast aluminum base plate, a go / no-go gauge for detecting the size of product holes, and a dial indicator for detecting the product profile. The cast aluminum base plate is provided with a reference hole for coordinate measuring machine (CMM) positioning and a positioning mechanism for positioning the frame product. The positioning mechanism includes a positioning pin for engaging with the holes in the frame product and a clamping screw for fixing the frame product. The cast aluminum base plate is also provided with multiple inspection units for detecting whether the frame product is qualified. Each inspection unit includes a flipping mechanism, a spring pusher for detecting the position of product holes or the profile of product bosses, and a cylindrical inspection rod for detecting the coaxiality of fan blade matching holes. The flipping mechanism includes a support frame mounted on the cast aluminum base plate. The support frame is connected to a flipping frame, and the flipping frame is connected to a simulation block. The simulation block is equipped with a dial indicator.

[0007] As a preferred embodiment of this invention, the springs used for detecting the position of the product hole are arranged symmetrically on the left and right sides.

[0008] As a preferred embodiment of this invention, four springs for detecting the profile of the product boss are provided, located on the opposite side of the flipping mechanism.

[0009] As a preferred embodiment of this invention, the cast aluminum base plate is provided with a handle for easy handling.

[0010] As a preferred embodiment of this invention, the flipping frame is rotatably connected to the support frame and fixed to the support frame by a knob bolt.

[0026] The following will refer to Figures 1 to 4 The working principle of this utility model will be explained.

[0027] Before testing, first clean the fixture and visually inspect it to determine whether it is in the open position, especially the flipping mechanism, so that the fixture as a whole is in a non-working state.

[0028] 1: Assembly Positioning

[0029] 1) Place the product on the inspection fixture, insert the positioning pin 41 into the inspection fixture, and then tighten the product with the corresponding clamping screw 42. Then close the flipping mechanism 5 to put the entire inspection fixture into working condition.

[0030] 2: Assembly Inspection:

[0031] 1) Use a spring tap 62 to inspect the profile of the product boss and determine whether the gap GAP=0.5 is acceptable;

[0032] 2) Use a spring pusher 61 to check the position of the holes in the product, that is, check whether the positions of the 6 Φ7.2 round holes are qualified;

[0033] 3) Use a spring pusher 61 to check the position of the product holes, that is, check whether multiple non-circular hole positions are qualified;

[0034] 4) Use go / no-go gauge 2 to check the product outline and hole dimensions;

[0035] 5) Use a dial indicator 3 to check the product outline, with a calibration distance of 50.

[0036] 6) Use cylindrical testing rod 7 to test the coaxiality of the fan blade matching hole.

[0037] Based on the results of each testing unit (such as whether the pin can pass, whether the reading is out of tolerance, whether the go / no-go gauge is not going, etc.), the operator makes a comprehensive judgment on whether the product is qualified.
