Abstract
The utility model provides a kind of clamping fixture for drilling, be provided with lock tire in the middle part of clamping fixture for drilling and move forelock key, on clamping fixture for drilling, side is positioned at lock tire and moves forelock key horizontal center line and be provided with hole, and in hole, bottom is provided with plug, plug top mounting spring, spring top is provided with alignment pin.Clamping fixture for drilling of the present utility model, during machining boreholes, can ensure the symmetry of lower opening on part, improve the positional precision of hole in piece part, namely improve element precision; And the design of this clamping fixture for drilling also has certain versatility, be applicable to the machining in diverse location hole, both reduced mold and changed number of times, and improve operating efficiency, also reduce production cost.
Description
Technical field
The utility model relates to dish type component processing technique field, particularly relates to the balancing frame processing technique field inside automobile engine shock absorber.
Background technology
In manufacture process, all there is blind hole balancing disc component (balancing frame as inside automobile engine shock absorber) upper and lower end face, and have a lot of similar products, the symmetry of upper and lower blind hole, it is one of processing difficulties, prior art is difficult to the Working position that can find hole fast and accurately, thus can not ensure the positional precision of hole in piece part.
Utility model content
Need to find fast and accurately with the Working position in the dish type component hole at other positions of processing, location, hole, the positional precision ensureing hole in piece part, the utility model provides a kind of clamping fixture for drilling.
The technical scheme that the utility model is adopted for achieving the above object is: clamping fixture for drilling, be provided with lock tire in the middle part of clamping fixture for drilling 1 and move forelock key 2, on clamping fixture for drilling 1, side is positioned at lock tire and moves forelock key 2 horizontal center line and be provided with hole 3, in hole 3, bottom is provided with plug 5, plug 5 top mounting spring 6, spring 6 top is provided with alignment pin 4.
Described clamping fixture for drilling 1 is disc.
Clamping fixture for drilling of the present utility model, during machining boreholes, can ensure the symmetry of lower opening on part, improve the positional precision of hole in piece part, namely improve element precision; And the design of this clamping fixture for drilling also has certain versatility, be applicable to the machining in diverse location hole, both reduced mold and changed number of times, and improve operating efficiency, also reduce production cost.

Detailed description of the invention
Clamping fixture for drilling structure of the present utility model as depicted in figs. 1 and 2, be provided with lock tire in the middle part of clamping fixture for drilling 1 and move forelock key 2, on clamping fixture for drilling 1, side is positioned at lock tire and moves forelock key 2 horizontal center line and be provided with hole 3, in hole 3, bottom is provided with plug 5, plug 5 top mounting spring 6, spring 6 top is provided with alignment pin 4.
Fig. 5 is the balancing frame inside automobile engine shock absorber, and this clamping fixture for drilling is the tooling auxiliary tool researched and developed for this series products specially, uses this mold, can find locating hole fast, the axiality of lower opening in guarantee.During use, find the center of circle of work 10, positioning workpieces 10 on the workbench of numerical control mill or machining center.Then, with workpiece 10 center for coordinate, find the position of alignment pin 4, fixing clamping fixture for drilling 1, clamping fixture for drilling 1 top arranges pressing plate 7, and as shown in Figure 3, clamping fixture for drilling 1, pressing plate 7 and workpiece 10 are fixed on workbench 12 by lead screw 8 and holding screw 9 pressing plate 7 structure, clamping fixture for drilling 1 both sides are provided with locating piece 11, go integral installation structure as shown in Figure 4.After so any blind hole rotates to alignment pin 4 position, under alignment pin 4 does not have the effect of pressure again, spring 5 by alignment pin top in blind hole, will play positioning action, thus ensure that the blind hole position degree of workpiece.During machining boreholes, the symmetry of lower opening on part can be ensured, improve the positional precision of hole in piece part, namely improve element precision; And the design of this clamping fixture for drilling also has certain versatility, be applicable to the machining in diverse location hole, both reduced mold and changed number of times, and improve operating efficiency, also reduce production cost.
