Abstract
The utility model provides a kind of multilayer thin-walled parts interference fit hole to assemble with drawing pin assembly.The technical solution of the utility model is: the assembling of a kind of multilayer thin-walled parts interference fit hole is with drawing pin assembly, comprise cover, plug, spring, nut, draw pin, shelf and panel, described shelf is provided with panel, cover is through after panel and shelf, locate on the top of the shelf by nut check, cover endoporus upper end be provided with it movable coordinate draw pin, its endoporus lower end is provided with the plug of threaded engagement with it, and pressure mounting of the spring is at plug and draw between pin.The beneficial effects of the utility model are: structure is simple, easy to use, has both solved multilayer thin-walled parts interference fit hole assembly quality problem, and has substantially increased production efficiency again.
Description
Technical field
The utility model relates to the assembling of a kind of multilayer thin-walled parts interference fit hole with drawing pin assembly, belongs to machining Work tool technical field.
Background technology
In Automatic manual transmission operation, often can run into the assembling of some multi-layer thin wall pored components, if these multilayer thin-walled hole in piece part adopt matched in clearance tolerance, be relatively easy to when assembling bearing pin, but, if the hole inside these multilayer thin-walled parts adopts matched in clearance, and the Kong Ze of ragged edge adopts interference fit, just difficult for very much when assembling bearing pin, the part that even also there will be the inside is damaged by pressure by bearing pin and produces the situation of waste product, because the hole for interference fit must adopt the method squeezed into or be pressed into bearing pin can be loaded, and when squeezing into or be pressed into bearing pin, vibration must be produced, make the hole dislocation originally aligned, so in the process squeezed into or be pressed at bearing pin, the part of the inside will be squeezed wound and even damage by pressure by bearing pin.
Summary of the invention
The purpose of this utility model is just to provide the assembling of a kind of multilayer thin-walled parts interference fit hole with drawing pin assembly, for solving the problem.
The technical solution of the utility model is: the assembling of a kind of multilayer thin-walled parts interference fit hole is with drawing pin assembly, comprise cover, plug, spring, nut, draw pin, shelf and panel, described shelf is provided with panel, cover is through after panel and shelf, locate on the top of the shelf by nut check, cover endoporus upper end be provided with it movable coordinate draw pin, its endoporus lower end is provided with the plug of threaded engagement with it, and pressure mounting of the spring is at plug and draw between pin.
The beneficial effects of the utility model are: structure is simple, easy to use, has both solved multilayer thin-walled parts interference fit hole assembly quality problem, and has substantially increased production efficiency again.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to accompanying drawing 1, the assembling of a kind of multilayer thin-walled parts interference fit hole is with drawing pin assembly, comprise cover 1, plug 2, spring 3, nut 4, draw pin 5, shelf 6 and panel 7, described shelf 6 is provided with panel 7, cover 1 is through after panel 7 and shelf 6, by nut 4 locking positioning on shelf 6, overlap 1 endoporus upper end be provided with it movable coordinate draw pin 5, its endoporus lower end is provided with the plug 2 of threaded engagement with it, and spring 3 is fitted in plug 2 and draws between pin 5.The utility model is real oppositely draws pin assembly for one, during use, first need the thin-walled parts 8 filling bearing pin 9 to pile in order to fold all, and the pilot hole of its each layer is aligned, it being contained in together draws on pin 5 again, because the diameter drawing pin 5 is adopt dynamic cooperation with the pilot hole of each layer of thin-walled parts 8, and there is chamfering on top, even if the pilot hole of each layer of thin-walled parts 8 is not too correct to obtaining, drawing pin 5 is also be easy to load, then the bearing pin 9 that will assemble is pressed into along the vertical direction of drawing pin 5, while constantly entering at bearing pin 9, draw pin 5 also in continuous decline, spring 3 is also in continuous contraction, so draw pin 5 from assembling until assemble complete, lead bearing pin 9 to assemble always, so just effectively ensure that assembly quality, after assembling terminates, the thin-walled parts 8 assembled is taken off, draw pin 5 and automatically return to original position under the tension force effect of spring 3, use in order to assembling next time.
