A kind of ball stud fixed structure
Technical field
The invention belongs to automobile component field, the fixed structure that particularly a kind of ball stud coordinates with rubber sleeve.
Background technique
When some parts need to be fixed on the matrix part of continuous vibrations, as the cover cap on motor, because the vibrations of matrix part can cause being assembled parts, follow matrix and constantly shake, easily cause being assembled that parts immovable point is loosening even comes off.
In order to solve the above problems, conventionally use a plurality of bolt immovable points, but must just can carry out bolt and fix being assembled on parts perforate, this has just destroyed the good appearance that is assembled parts, for some, to the higher build-up member of appearance requirement, just should not adopt this means of fixation; Adopt bolt fixedly to make to be assembled parts simultaneously and form being connected of rigidity with matrix part, be assembled parts and can be constantly subject to the impact that vibrations produce from matrix part, easily cause being assembled the inefficacy of parts.
Summary of the invention
The object of this invention is to provide the fixed structure that a kind of ball stud coordinates with rubber sleeve, for connecting the matrix part that is assembled parts and constantly shakes.
The present invention is achieved by the following technical solutions:
A fixed structure, includes ball stud, rubber sleeve, is assembled parts and matrix part composition; Described ball stud is comprised of ball head and bolt part; Described being assembled is provided with deck on parts; Rubber sleeve is that feather is spherical, the umbrella portion that includes spherical groove and be connected with spherical groove outer; The spherical groove of rubber sleeve inserts in deck; The ball head of ball stud is inserted in spherical groove, and bolt part and the matrix part of ball stud are fixed.
The base portion of described deck protrudes from the surface that is assembled parts.
The described deck inwall that is assembled parts is provided with at least one circle annular protrusion; The outer wall of described rubber sleeve is provided with the groove coordinating with annular protrusion.
The nut that on described matrix part, welding coordinates with the bolt part of ball stud in advance.
The opening portion diameter of described spherical groove is less than the diameter of ball stud ball head, ball head and spherical groove interference fit.
Described spherical groove is plane with being assembled the face that parts contact.
The invention has the beneficial effects as follows:
1) easy to operate while assembling, directly ball stud is inserted to rubber sleeve, utilize the interference fit of bulb and spherical groove that parts are fixed.
2) being assembled parts surface does not need perforate, has retained perfect appearance.
3) rubber sleeve has elasticity, can shake the impact producing by absorption base body component.
4) height of ball stud can be adjusted according to different assembly environments, to meet the assembling demand of multiple assembly environment.
5) rubber sleeve opening is V-type, facilitates the assembly manipulation of ball stud and rubber sleeve.

Embodiment
By specific embodiment, describe technological scheme of the present invention in detail below, should be understood that, following embodiment is only exemplary, only can be used for explaining and technological scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
As shown in Figure 1 to Figure 3, a kind of ball stud fixed structure, includes ball stud 1, rubber sleeve 2, is assembled parts 3 and matrix part 4 compositions.
Described ball stud 1 is comprised of ball head 7 and bolt part 8.
Described being assembled on parts 3 is provided with deck 5, and in the present embodiment, the base portion of deck 5 protrudes from the surface that is assembled parts.
Rubber sleeve 2 is that feather is spherical, the umbrella portion that includes spherical groove 9 and be connected with spherical groove outer; The spherical groove 9 of rubber sleeve 2 inserts in deck 5; The ball head 7 of ball stud 1 is inserted in spherical groove 9, and the bolt part 8 of ball stud 1 is fixing with matrix part 4.In the present embodiment, the nut 6 that on matrix part 4, welding coordinates with the bolt part 8 of ball stud 1 in advance.
Described deck 5 inwalls that are assembled parts 3 are provided with at least one circle annular protrusion; The outer wall of described rubber sleeve 2 is provided with the groove 10 coordinating with annular protrusion.
The opening portion diameter of described spherical groove 9 is less than the diameter of ball stud ball head, ball head and spherical groove interference fit.
In the present embodiment, spherical groove is plane with being assembled the face that parts contact.
Implementation step is, first by bolt part 8 and welded nut 6 are tightened, ball stud 1 is fixed on matrix part 4, again rubber sleeve 2 and the deck 5 being assembled on parts 3 are combined, then ball stud 1 is inserted in rubber sleeve 2, bulb 7 and spherical groove 9 are combined together, generally adopt 3-5 this structure will be assembled parts and fixedly secure.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present invention is by claims and be equal to and limit.
