Description

Technical Field

[0001] The utility model relates to the field of interior instrument panel product detection, in particular to a frame that can simultaneously meet the universal needs of instrument panel assembly inspection tools for multiple vehicle models. Background Art

[0002] Instrument panels are located in the cockpit. Existing technologies lack a standardized framework for instrument panel assembly inspection fixtures, as the dimensions of each vehicle's instrument panel assembly vary significantly in spatial coordinate systems. Consequently, the fixture design structures vary widely, requiring numerous parts to be processed to achieve their functions. This complex structure makes it impossible to interchange and inspect multiple instrument panel products. A different inspection fixture is developed for each project, and each fixture must be stored for the entire product manufacturing cycle, resulting in a significant increase in factory floor space. Furthermore, since the framework is the primary structure of the instrument panel inspection fixture, it requires high precision, resulting in a long development cycle and high costs. Repeated framework development not only increases fixture manufacturing costs but also prolongs the development cycle for product testing. Furthermore, since each developed product cannot be reused after an upgrade, resources are wasted. Utility Model Content

[0020] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0021] The instrument panel assembly, which houses various indicators and the ignition switch in the vehicle's cabin, provides the driver with essential information about vehicle operating parameters. Most instrument panels are mounted on a crossbar, with the front end attached to the body sheet metal and the sides aligned with the A-pillars and door panels. Based on these characteristics and the size differences between sedans and SUVs, a universal instrument panel assembly inspection fixture framework has been designed. Adjustable distance features are incorporated into the front, left, right, and rear sections to enable interchangeable inspection.

[0022] like Figure 1 The universal instrument panel assembly inspection fixture frame consists of a base plate 1, with brackets 1 (2), 2 (3), and 3 (4) mounted perpendicular to it. To accommodate the size differences between sedan and SUV instrument panels, brackets 1 (2), 2 (3), and 3 (4) are equipped with equally spaced mounting holes. These holes allow for adjustable mounting of removable panels 1 (5) and 2 (6) in front of and away from the cab, enabling inspection of instrument panels of varying sizes. Multiple digital dial indicators 28 are integrated into removable panels 1 (5) and 2 (6). Interchanging these panels allows for rapid front-end inspection of different vehicle models.

[0023] Adjustment blocks 1-7, 2-8, and 3-9 are installed directly in front of brackets 1-2, 2-3, and 3-4, respectively. These adjustment blocks are interchangeable parts for each project and are selected based on the distance between the instrument panel product and the front-to-back crossbar. Adjustment blocks 1-7 and 2-8 are equipped with locating pins 10 and 11 for mounting positioning plate 12. Adjustment blocks 2-8 and 3-9 are equipped with locating pins 13 and 14 for mounting positioning plate 2-15. Positioning plates 1-12 and 2-15 provide mounting points for instrument panel products. Locating pins 10 and 13 allow for multiple disassembly and reassembly, ensuring repeatable accuracy and meeting the installation and positioning requirements for multiple instrument panel products. Wear-resistant block 1-30 is installed on adjustment block 1-7, while wear-resistant block 2-16 is installed on adjustment block 2-8. Wear-resistant blocks 1-30 and 16 are made of a relatively hard material, ensuring reliable accuracy after repeated disassembly and assembly of adjustment block 1-7 and positioning plate 1-12, while also facilitating replacement.

[0024] Mounted on bracket 1 (2) is a flip base (17). A hole is provided in the base (17) for mounting a pivot (18). A zero-clearance fit is achieved between pivot (18) and the base (17). This pivot (18) allows the flip arm (19) to open and close. In the open state, the maximum angle engages with a stop (20). The flip arm (19) is secured to a connecting block (21) via threads and a locating pin. This connecting block (21) is interchangeable and can accommodate matching detection blocks for different vehicle models and door panel areas.

[0025] A sliding base 22 is installed on the base plate 1, and a sliding rail 23 is installed on the sliding base 22. The sliding rail 23 and the slide groove 24 can realize sliding motion. A positioning block 25 is installed on the slide groove 24. The positioning block 25 is used to provide a support point for the lower part of the instrument panel product. Considering the size difference between sedans and SUVs, the support positions are inconsistent on the left and right. A gear hole is set on the sliding base 22, and the slide groove 24 drives the positioning block 25 to slide and is locked at any gear hole by a limit pin 26.

[0026] Preferably, three rows of equidistant gear mounting holes are provided on bracket 1 2, bracket 2 3 and bracket 3 4, respectively, with a spacing of 85 mm; the removable plate 1 5 and the removable plate 2 6 can be adjusted front and rear to three travel gears: original position, 85 mm away from the cockpit, and 170 mm away from the cockpit, to adjust the size difference between the dashboards of sedans and SUVs.

[0027] Preferably, the sliding base 22 is provided with shift holes with distances of 0, 30 mm, 60 mm, and 90 mm relative to the starting position to limit the left and right positions of the positioning block 25 for adjusting the size difference between the dashboards of sedans and SUVs.

[0028] In order to ensure the convenience of repeated disassembly and assembly, the detachable plate 1 5, the detachable plate 2 6, the flip arm 19, and the connecting block 21 are all provided with weight-reducing holes.
