Embodiment Construction
[0032] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0033] A non-standard nut and bolt structure, including "±" type bolts 1 and "I" type nuts 3, the outer side of the "±" type bolts 1 is fixed with bolt stamping washers 2, and the "I" type nuts 3 One end is fixedly connected with a nut stamping washer 4 .
[0034] Wherein, the diameter of the bolt stamping washer 2 is greater than the diameter of the "±" type bolt 1, and the diameter of the nut stamping washer 4 is greater than the diameter of the "I" type nut 3.
[0035] A processing technology for a non-standard nut and bolt stru...

The invention discloses a non-standard nut and bolt structure. The non-standard nut and bolt structure comprises a bolt shaped like a Chinese Character Shi and an H-shaped nut. The outer side of the bolt shaped like a Chinese Character Shi is fixedly sleeved with a bolt stamping washer. The non-standard nut and bolt structure has the following beneficial effects that the production efficiency is improved, specifically, the problem that similar parts must adopt a turning technology is solved, the production efficiency is greatly improved, and the current turning efficiency is probably 60 s / piece while the current stamping and cold heading efficiency is 5s / piece; material spillage is reduced, specifically, if an original overall design is adopted, the raw material selective size may be quitelarge, using of raw materials can be reduced to a large extent after the structure is split, wasting is reduced, the material utilization rate basically reaches up to 95% or above, and the original design turning technology may waste much more raw materials; and environment friendliness is achieved, specifically, in the production process of a design mechanism, almost no slag or waste product isproduced, environment friendliness is achieved, and an original design structure uses a lot of turning fluid in the production process and produces turning waste and the like which pollute the environment.
Description
technical field [0001] The invention discloses a non-standard nut and bolt structure, in particular relates to a non-standard nut and bolt structure and a processing technology thereof, and belongs to the field of automobile assembly parts. Background technique [0002] Automobile injection molding exterior trim parts and car body assembly are inseparable from bolts and nuts. These bolts and nuts are generally assembled with the doghouse of the injection molded parts in the "Shi" or "I" type. At present, the design of this kind of products is generally designed with the same material, which makes this kind of parts unable to be like other standard bolts. The nut adopts cold heading and thread rolling process to complete the processing directly. The current process is cold heading first, then turning, and finally thread rolling, and some even use turning technology for processing. The turning process greatly increases the product cost, and there are problems such as low eff...
