Description
Technical Field
The utility model relates to a mounting hole structure, concretely relates to a part mounting hole structure for on aluminum alloy material.
Background
At present, the mode of mounting parts on aluminum alloy materials is to use an internal thread fastener, namely a steel wire thread insert, to fasten steel parts in the aluminum alloy materials. This type of mounting has the following disadvantages: (1) a special tapping tool is needed to pre-tap the aluminum alloy body, the assembly process is complex, and the efficiency is low; (2) the quality of the pre-tapping of the steel wire thread insert on the aluminum alloy body is inconsistent, and the rejection rate is high, so that the mounting hole needs to be reworked, the assembly quality is low, and the work progress is delayed; (3) after the steel wire thread insert is disassembled and assembled for many times, the aluminum alloy body can be extruded by the thread insert, and the mounting hole is subjected to plastic deformation, so that the mounting performance is failed; (4) the mounting holes of the steel wire thread insert and the body are of cylindrical structures, so that the mounting piece can rotate around one degree of freedom direction of the mounting hole; although the bolt is used for fastening, the phenomenon of torsion slip can occur after multiple times of disassembly and assembly or in a long-time working state; (5) the torque test of the mounting hole has certain failure rate and unstable quality.
SUMMERY OF THE UTILITY MODEL
The utility model provides a part mounting hole structure to solve the not enough of above-mentioned background art existence.
In order to achieve the above object, the utility model provides a part mounting hole structure, including setting up the mounting hole on the plate body, the mounting hole is by the square counter bore that is located the plate body surface and being located the quad slit of square counter bore bottom is constituteed, square counter bore width is greater than the quad slit width, and constitutes a shoulder hole big-end-up between the two, the quad slit internal fixation has squarely to attach the seat, squarely attach the seat upper end and be provided with the second mounting hole, the second mounting hole is global to be provided with the internal thread.
As the preferred arrangement of the utility model, the height of the square counter bore is not more than one fifth of the height of the square hole.
As the utility model discloses an optimal setting, square attach the seat with quad slit welded fastening.
As the utility model discloses a preferred setting, the second mounting hole link up square attaching seat.
As the utility model discloses an optimal setting, the plate body is the aluminum alloy material.
The utility model has the advantages that: the utility model has simple structure, reasonable design, high consistency of installation quality, reliable quality, no need of tapping by special tools and simple assembly; the bearing capacity and the strength of the threads are high, and the load of the mounting part can be effectively met; the mounting piece is more shock-resistant, and the anti-loosening effect can be effectively improved; the fatigue resistance of the mounting part is higher, and the mounting capacity and the service life are longer; the mounting hole and the composite material auxiliary seat are of square structures, so that the torsion of the mounting piece can be effectively increased.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.
Examples
Referring to fig. 1, in order to realize the above-mentioned purpose, the embodiment of the utility model provides a part mounting hole structure, including setting up mounting hole 2 on plate body 1, mounting hole 2 is by the square counter bore 3 that is located the plate body surface and being located the quad slit 4 of the 3 bottoms of square counter bore is constituteed, square counter bore 3 width is greater than quad slit 4 width, and constitute a big-end-up's shoulder hole between the two, quad slit 4 internal fixation has square to attach seat 5, square attach 5 upper ends of seat and be provided with second mounting hole 6, second mounting hole 6 is global to be provided with the internal thread.
As an optimized arrangement of the embodiment of the present invention, further, the height of the square counter bore 3 is not more than one fifth of the height of the square hole 4.
As the preferred setting of the embodiment of the utility model, further, square attach seat 5 with quad slit 4 welded fastening.
As a preferable configuration of the embodiment of the present invention, further, the second mounting hole 6 penetrates the square auxiliary seat 5.
As the preferred setting of the embodiment of the present invention, further, the plate body 1 is made of an aluminum alloy material.
In the embodiment, the square counter bore 3 is arranged to facilitate the welding and fixing of the square auxiliary seat 5 and the square hole 4; when the square auxiliary seat is used, a part to be installed is matched and fastened with the internal threads of the square auxiliary seats 5 through the bolts, so that the consistency of installation quality is high, and the quality is reliable; meanwhile, the mounting hole 2 and the auxiliary seat 5 are both square in shape, so that the torque can be effectively increased; by adopting the utility model, the aluminum alloy plate body is not required to be tapped by special tools, only bolts and threads are required to be matched, and the assembly is simple; meanwhile, compared with a tapping installation steel wire thread insert, the thread has higher bearing capacity, and the load of an installation part can be effectively met; because the square auxiliary seat 5 is adopted, the bolt is not directly connected with the plate body, the square auxiliary seat 5 can absorb partial vibration in the vibration process of the plate body, the mounting piece has stronger vibration resistance effect, the anti-loosening effect can be effectively improved, meanwhile, the fatigue resistance effect of the mounting piece is higher, and the service life is longer; the mounting hole and the auxiliary seat are of square structures, so that the torsion of the mounting piece can be effectively increased.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "disposed," "connected," "fixed," "screwed" and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
Furthermore, those skilled in the art will appreciate that while some embodiments described herein include some features included in other embodiments, rather than other features, combinations of features of different embodiments are meant to be within the scope of the invention and form different embodiments.
