Description

Technical Field

[0001] This utility model relates to the field of automotive inspection tool technology, specifically a hole measuring tool for automotive main airbag assembly parts. Background Technology

[0002] The assembly parts in automotive safety airbags usually require drilling. The existing product processing technology is to punch from the inside out. Wear and defects of the punch can lead to defects such as waste material blocking the side holes, missed punching, and holes not being punched through during the processing.

[0003] Therefore, we propose a hole-testing tool for assembling automotive main airbag components. Utility Model Content

[0004] The purpose of this invention is to provide a hole measuring tool for assembling automotive main airbag parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole measuring tool for automotive safety main airbag assembly parts, used for measuring product components, including a base plate, with a side plate and a half-side plate fixedly connected to both ends of one side of the base plate by bolts respectively, and a punch plate fixedly disposed on the top of the base plate between the side plate and the half-side plate, with a punch fixedly disposed on the punch plate.

[0006] The product component has two rows of holes on its surface, with each row containing a certain number of holes, and the hole wall thickness is 2.25 mm.

[0007] The punch plate is provided with two rows of mounting holes that match the punches, and each row of mounting holes is provided with a number of punches, with each punch protruding 2.5mm from the punch plate.

[0008] A baffle is fixedly connected to the top of the side plate by bolts.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] This utility model covers the inspection of all holes in a product, and the punch can penetrate the wall thickness of the product hole. It has a simple structure, is practical and convenient, and has strong comprehensive testing capabilities. It can detect whether the number of holes on the product meets the design requirements more quickly and accurately, thus achieving the purpose of accurate inspection. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a hole measuring tool for assembling automotive safety main airbag parts, used to measure product component 7, including a base plate 1, with a side plate 4 and a half side plate 6 respectively fixedly connected to both ends of one side of the base plate 1 by bolts, and a punch plate 2 fixedly disposed on the top of the base plate 1 between the side plate 4 and the half side plate 6, and a punch 3 fixedly disposed on the punch plate 2.

[0018] Product component 7 has two rows of holes on its surface, with 12 holes in each row and a hole wall thickness of 2.25 mm.

[0019] The punch plate 2 is provided with two rows of mounting holes that match the punches 3, and each row of mounting holes is provided with 14 punches 3, and the length of each punch 3 protruding from the punch plate 2 is 2.5mm.

[0020] A baffle 5 is fixedly connected to the top of the side plate 4 by bolts.

[0021] When using this utility model, such as Figure 3 The inspector or operator places product component 7 on the punch plate 2, initially aligning the two holes (one in each of the upper and lower rows) on product component 7 with the punches 3 on the punch plate 2. Then, the product component 7 is allowed to fall freely. This allows the inspector to determine if the holes on product component 7 meet the requirements. If product component 7 falls freely out of the fixture without any obstruction, it indicates that the number of holes on product component 7 is acceptable. If product component 7 cannot fall freely out of the fixture and gets stuck at some point, it indicates that the number of holes on product component 7 is unacceptable (meaning the product may have defects such as waste material blocking holes, missing holes, or holes not being punched through).

[0022] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
