Description
Technical field
The present invention relates to engineering element technical fields, and in particular, to a kind of screw that installation effectiveness can be improved.
Background technique
With the development of auto industry, new energy, lightweight etc. are widely applied increasingly, and need to carry out in the assembly of automobile
A large amount of welding procedure, such as spot welding, arc-welding and SPR, technical staff can select according to the actual situation required technique into
Row operation.However, these techniques are other than all relatively complicated, in some small places in link position space, existing spot welding, arc
The techniques such as weldering and SPR are difficult to operate, also, can not directly be welded between plate material not of the same race.
Summary of the invention
For the defects in the prior art, the object of the present invention is to provide a kind of screws that installation effectiveness can be improved.
It provides according to the present invention
A kind of screw that installation effectiveness can be improved, comprising: tail portion, screw thread guide part and thread rod part；
The screw thread guide part is provided on the screw thread guide part and leads between the tail portion and the thread rod part
To line, the leading line is gradually thicker from front end to rear end, and the front end of the leading line connects the tail portion, the leading line
Rear end connects the screw thread of the thread rod part.
Preferably, further include:
Head: positioned at the outer end of the thread rod part, the head and the thread rod part junction are provided with deep gouge.
Preferably, the side far from the thread rod part on the head is provided with interior driving head or outer driving head.
Preferably, the interior driving head includes interior hexagonal or interior illiciumverum, the outer driving head includes outer-hexagonal or outer illiciumverum.
Preferably, the tail portion is parabolic shape.
Preferably, the length and width of the tail portion are unequal.
Compared with prior art, the present invention have it is following the utility model has the advantages that
The present invention can be such that tapping after plate thermal deformation rivets by high speed rotation, and without being welded, simple and effective can
Position suitable for link position narrow space.In addition, can also be applied to the connection between plate material not of the same race.
Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention,
Objects and advantages will become more apparent upon:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the enlarged drawing of tail portion of the present invention
Fig. 3 is the cross-sectional view of tail portion of the present invention.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, several changes and improvements can also be made.These belong to the present invention
Protection scope.
As shown in Figure 1, a kind of screw that installation effectiveness can be improved, comprising: tail portion 1, screw thread guide part 2,3 and of thread rod part
Head 4.
Tail portion 1 is parabolic shape, and screw thread guide part 2 is between tail portion 1 and thread rod part 3, on screw thread guide part 2
It is provided with leading line 21, leading line is gradually thicker from front end to rear end, and the front end of leading line 21 connects tail portion 1, leading line 21
The screw thread of rear end connection screw thread bar portion 3.
Head 4 is located at the outer end of thread rod part 3, head 4 and 3 junction of thread rod part is provided with deep gouge 41, brill is stayed in storage
Cause anti-exoncoma in hole.The side of the separate thread rod part 3 on head 4 is provided with interior driving head 42 or outer driving head.Interior driving head packet
Interior hexagonal or interior illiciumverum are included, outer driving head includes outer-hexagonal or outer illiciumverum.
As shown in Figures 2 and 3, the length and width of tail portion 1 are unequal, i.e., the length of A, B differ, and the length of C be consistently greater than A or
B.Such mechanism design is conducive to tail portion 1 and pierces in material.
Working principle of the present invention is as follows:
Tail portion 1 is positioned into contact plate first, high temperature is generated to make plate thermal deformation, the plate of deformation by high speed rotation
Material can surround 1 cylindrical form of tail portion.After screw wears out plate, plate contacts thread rod part under the guiding of screw thread guide part 2
3, to form screw thread.Screw continues to be screwed into and lock.
The present invention has the advantages that
It a, can connecting dissimilar material；
B, it realizes single side connection, makes to connect more convenient；
C, it can be selected according to parts themselves whether pre-drilled cavity；
D, what the generation of big thread contact face was big screws torque；
E, it is bigger to unclamp torque；
F, watertightness is good, and dynamic load is good；
G, more environmentally friendly compared with spot welding, arc-welding (no splashing and welding slag)；
H, bonding strength is greater than spot welding and SPR；
I, screw thread can repeat to lock, and screw is convenient for disassembly and assembly, convenient for recycling.
In the description of the present application, it is to be understood that term " on ", "front", "rear", "left", "right", " is erected at "lower"
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "inner", "outside" is orientation based on the figure or position
Relationship is set, description the application is merely for convenience of and simplifies description, rather than the device or element of indication or suggestion meaning are necessary
It with specific orientation, is constructed and operated in a specific orientation, therefore should not be understood as the limitation to the application.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
