Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is described in further detail, it is therefore an objective to help those skilled in the art that the design of the present invention, technical scheme are had more complete, accurate and deep understanding, and contribute to its enforcement。
As depicted in figs. 1 and 2, one automotive hub Drilling operation fixture of the present invention, is for automotive hub is added and carries out clamping boring tapping female bore man-hour。This fixture includes base plate 1, base plate 1 be provided with multiple parallel supporting plate 4, for automotive hub is pressed on the hold-down mechanism on supporting plate 4 and be used for automotive hub location detent mechanism, supporting plate 4 end face is location plane, hydraulic cylinder 6 that hold-down mechanism includes being vertically arranged, horizontally disposed pressing plate 9 and be located at the nylon pressure head 8 compressing end of pressing plate 9, pressing plate 9 is strip, one end of pressing plate 9 is fixing with the piston rod of hydraulic cylinder 6 to be connected, and the other end is for compressing end。When clamping, being placed in the location plane that supporting plate 4 end face is formed in the ventricumbent mode in its end by wheel hub, the end face of supporting plate 4 wants isoplanar to polish, to ensure that its flatness forming locating surface meets the technology requirement that wheel hub Working position adjusts。Nylon pressure head 8 can protect wheel hub, it is prevented that wheel hub is caused damage by hydraulic cylinder 6 in compaction process。
Specifically, base plate 1 is suitable with the size dimension of wheel hub, and the end face of base plate 1 is plane, as illustrated in fig. 1 and 2, the end face ad-hoc location at base plate 1 is provided with two supporting plates 4 altogether, and two supporting plates 4 are parallel, supporting plate 4 is the flat board of strip, between two supporting plates 4 and be spaced a distance。
As preferably, supporting plate 4 is to be fixed on base plate 1 by two screws, and the length direction of supporting plate 4 is paralleled with the length direction of base plate 1。Supporting plate 4 is adopted and is screwed, when multiple clamping causes that supporting plate 4 wear extent is excessive, it is possible to convenient replacing in time。
As depicted in figs. 1 and 2, detent mechanism includes two alignment pins being located on base plate 1, and the location division of one of them alignment pin is cylindrical, is circular alignment pin 3, and the location division of another alignment pin is rhombus, is diamond positioning pin 5。As in figure 2 it is shown, two alignment pins are positioned at the inner side of two supporting plates 4, on wheel hub, choosing has the location hole suitable with two alignment pins。Wherein, circular alignment pin 3 is located in one of the side, end of supporting plate 4, and diamond positioning pin 5 is positioned at the side, end of another supporting plate 4, and with circular alignment pin 3 for being staggeredly arranged。Base plate 1 arranges alignment pin, positions more accurately reliable during in order to ensure wheel hub clamping。These two alignment pins are also equipped with nylon locating pad to protect wheel hub from unnecessary scuffing, can change in time when locating pad generation excessive deformation in multiple clamping。
