Description
Technical Field
the invention relates to the field of tolerance regulators, in particular to the field of installation of more than 3 installation holes of two components or the field of installation of multiple fixed position spaces of more than two components, and particularly relates to a manual three-way tolerance regulator which is applied to accurately installing a hidden handle and an installation method thereof.
Background
The conventional door handle is divided into an outer handle structure and an inner handle structure, and the inner handle structure and the outer handle structure are separated by the outer door sheet metal, so that more fixing points are arranged on the handle; the hidden handle is formed by integrally slotting the outer metal plate of the vehicle door and is integrally embedded into the outer metal plate. The installation of the present hidden handle has the following problems:
(1) After the outer metal plate and the inner metal plate of the vehicle door are assembled and fixed, the inner metal plate and the outer metal plate have assembly deviation, and the height and the position of the inner metal plate and the outer metal plate have deviation in 3 directions, so that the appearance and the using effect of handle assembly are influenced, and therefore, the tolerance of X/Y/Z3 directions needs to be adjusted; the outer handle is a key point of the appearance design of the whole vehicle, and the requirement on matching between the outer handle and an outer metal plate is extremely high, so that the requirements on installation positioning of a hidden handle and tolerance adjustment in 3 directions are very high;
(2) Meanwhile, on the basis of the use characteristics of the automobile, the handle and the metal plate are generally required to be firmly fixed on the premise of adjusting the tolerance, and the looseness caused by vibration and shrinkage at different temperatures can be resisted;
(3) In addition, the structure in the door is complicated, and the inside has glass-frame riser, lock mechanism etc. to lead to the space narrow and small, the assembly difficulty.
in addition, tolerance regulators on the market at present or one-direction tolerance regulation are designed by metal materials, and the requirements of tolerance regulation in three directions cannot be met; or a plurality of parts, and the structure is complex, the cost is high and the bearing load is small although the tolerance adjustment in three directions is realized.
In addition, along with market changes and the development of electronic technology, automotive electronic parts are continuously increased, the functions are richer, more parts are required to be installed in an automotive body, the structure is narrower, the assembly is more complex, meanwhile, the electronic parts have higher requirements on the stability of fixation and the convenience of disassembly and assembly, the anti-seismic effect is good, and higher requirements are also required on the installation of the automotive parts. Meanwhile, in the current market, because of the lack of three-dimensional adjustment tolerance to constrain parts, for the convenience of assembly and maintenance, the gap between the parts is increased or the fixing effect is sacrificed by increasing the structure of automobile parts, so as to meet the requirement of the service space of a maintenance tool. At present, the common solutions are that the metal bolt is positioned and installed by a kidney-shaped hole, or the metal bolt is fixedly installed by forced deformation of a part fixing position, or the metal bolt only meets the position tolerance of one direction dimension and sacrifices the fixed installation of the other two direction dimensions, or the metal bolt is fixedly installed by adding a cushion block or a balance block. This also occurs in the mounting of fixed glass cleaning kettles, the mounting of fixed engine compartment parts, the mounting of fixed vacuum boosters, the mounting of fixed audio speakers, the mounting of fixed automotive air conditioning condensers, the mounting of fixed automotive dashboards, the mounting of fixed automotive lights, the mounting of fixed electrical boxes and brackets, the mounting of fixed automotive trunk brackets, and the like.

Step two, preassembling the hidden handle 4 into the grooves of the inner metal plate 5 and the outer metal plate 6, abutting the bottom surface of the adjusting stud 1 with the inner metal plate 5, and adjusting the side gap between the hidden handle 4 and the outer metal plate 6;
Sleeving the bolt 21 into the locking sheet 22, sequentially penetrating through the adjusting stud 1 and the bolt mounting through hole and the fixing nut 51 on the inner metal plate 5, and pre-locking the fixing nut 51 and the bolt 21; the fixed nut 51 is welded on the bottom end face of the inner metal plate 5 and is concentrically arranged with the bolt mounting through hole on the inner metal plate 5;
step four, referring to the step three, sequentially locking other fixing nuts 51 on the inner metal plate 5 to complete the installation of the whole hidden handle 4, the inner metal plate 5 and the outer metal plate 6, adjusting the gap between the outer metal plate 6 and the side edge of the hidden handle 4, and pre-locking the XZ-direction position;
Step five, a socket wrench is adopted to sleeve in the boss 13 of the adjusting stud 1 and rotate, Y-direction height adjustment is carried out, and Y-direction tolerance adjustment is completed when the surfaces of the hidden handle 4 and the outer metal plate 6 are flat;
And step six, after the tolerance adjustment in the Y direction is finished, finally locking the fixing nut 51 by the bolt 21, and realizing the final fixation in the XZ direction. Bolt assembly 2 passes bolt installation via hole and fixation nut 51 on adjusting stud 1, the interior panel beating 5 in proper order, will hide handle 4 and pass through bolt assembly 2 and adjusting stud 1 and fix on panel beating 5 including to lock through fixation nut 51.
Furthermore, the matching relationship between the adjusting stud 1 and the fixing base 3 is tight fit or excessive fit, and during assembly, a preset standard height is reserved in the Y direction between the fixing base 3 and the inner metal plate 5 so as to reduce the workload of manual adjustment and improve the working efficiency, wherein the standard height is determined according to actual experience.
The working principle is as follows: the tolerance adjustment of the height between the fixed base plane and the metal plate plane in the Y direction is manually realized by rotating the adjusting stud, and the height adjustment in the Y direction in a larger range can be realized; the hole position of the fixing nut is automatically aligned through the screwing action of the bolt, the tolerance of the center hole of the fixing base and the center of the metal plate fixing nut hole in the XZ direction is automatically adjusted, the XZ position is finally locked and fixed, and the tolerance adjustment in the XZ direction is realized.
the foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
