Description
Technical field
The utility model relates to a kind of drill jig for workpiece, is specifically related to a kind of drill jig of energy Quick-clamped.
Background technology
Drill jig is the jig guiding cutter to hole on workpiece or ream.The design feature of drill jig is apart from outside the location of workpiece, clamping device, the also position distribution in good grounds processed hole and the drill bushing arranged and bushing plate, in order to determine the position of cutter, and prevent cutter in process medium dip, thus ensure the positional precision in processed hole.
Conventional drill jig has fixed, swinging, convertible and cover-plate type 4 kinds, wherein fixed drill jig generally includes clamp body, bushing plate, screw rod, nut, pressing plate and drill jig sleeve, drill jig sleeve is arranged on bushing plate, bushing plate is fixed on clamp body, workpiece is placed on clamp body, by fastening nut, screw rod is moved, screw rod band dynamic pressure plate, thus by Work-sheet pressing.But this mode turning nut is often comparatively slow, and working (machining) efficiency is lower.
Utility model content
The purpose of this utility model is at the drill jig of the energy Quick-clamped providing a kind of working (machining) efficiency high.
For achieving the above object, base case of the present utility model is as follows:
The drill jig of energy Quick-clamped, comprise clamp body, bushing plate, drill jig sleeve and pressing plate, described drill jig sleeve is connected on bushing plate, bushing plate is connected with clamp body, also comprise eccentric cam, pull bar, locating flange and end cap, described locating flange is connected with clamp body, locating flange is provided with through hole, described pull bar interts in described through hole, pull bar one end and pressing plate hinged, the other end and described eccentric cam are rotationally connected, and eccentric cam is provided with cursor, described end cap is connected to locating flange near eccentric cam one end, and eccentric cam and end cap offset.
The principle of this programme: first workpiece to be processed is placed on locating flange, rotate the cursor on eccentric cam, due to pull bar one end and pressing plate hinged, the other end and described eccentric cam are rotationally connected, and when eccentric cam and end cap contact position go to the large side of eccentric throw by the side that eccentric throw is little, eccentric cam drives pull bar to move, simultaneously, pull bar pulls pressing plate to move, thus pressing plate by Work-sheet pressing on locating flange, so far complete the clamping of workpiece.
The advantage of this programme is: this programme adopts eccentric cam and pull bar to coordinate, during operation, by pulling cursor, thus enough make eccentric cam rotate rapidly, make arm-tie rapidly by Workpiece clamping, make compared with screw rod moves with existing by fastening nut, working (machining) efficiency significantly improves; In addition, because eccentric cam has the function of self-locking, after Workpiece clamping, decontrol cursor, operate more convenient.
Preferred version 1, to the further optimization of base case, is provided with packing ring between described end cap and eccentric cam.After being provided with packing ring, eccentric cam mainly with packing ring between phase mutual friction, the friction suffered by end cap is little, so can slow down wear of end cover.
Preferred version 2, to the further optimization of base case, described pressing plate is provided with open slot, and described clamp body is provided with the lead of insertion opening groove.Arm-tie is led by lead, can prevent pull bar in the process pulling pressing plate, and pressing plate offsets.
Preferred version 3, to the further optimization of base case, any one of preferred version 1,2, described locating flange is provided with keyway.By trade union college on locating flange time, positioned by key, the rotation in workpiece process can be avoided like this.
Accompanying drawing explanation
Fig. 1 is the structural representation of the drill jig embodiment of the utility model energy Quick-clamped.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: clamp body 1, locating flange 2, through hole 21, pressing plate 3, bushing plate 4, end cap 5, eccentric cam 6, pull bar 7, lead 8, packing ring 9, cursor 10, drill jig sleeve 11.
Embodiment is substantially as shown in Figure 1: a kind of can the drill jig of Quick-clamped, comprise clamp body 1, bushing plate 4, drill jig sleeve 11 and pressing plate 3, drill jig sleeve 11 is connected on bushing plate 4, bushing plate 4 is connected with clamp body 1 by bolt, also comprise eccentric cam 6, pull bar 7, locating flange 2 and end cap 5, locating flange 2 is socketed on clamp body 1, and locating flange 2 is also connected with clamp body 1 by bolt, locating flange 2 is provided with through hole 21, pull bar 7 interts in through hole 21, pull bar 7 one end and pressing plate 3 hinged, the other end and eccentric cam 6 are rotationally connected, eccentric cam 6 is provided with the jack of rectangle, cursor 10 is plugged in jack, end cap 5 is bolted at locating flange 2 near eccentric cam 6 one end, and eccentric cam 6 and end cap 5 offset.
Packing ring 9 is provided with between end cap 5 and eccentric cam 6.After being provided with packing ring 9, eccentric cam 6 mainly with packing ring 9 between phase mutual friction, the friction suffered by end cap 5 is little, weares and teares so can slow down end cap 5.
Pressing plate 3 is provided with open slot, and clamp body 1 is provided with the lead 8 of insertion opening groove.Arm-tie is led by lead 8, and can prevent pull bar 7 in the process pulling pressing plate 3, pressing plate 3 offsets.
Locating flange 2 offers keyway.By trade union college on locating flange 2 time, positioned by key, the rotation in workpiece process can be avoided like this.
Specific works flow process:
First workpiece to be processed is placed on locating flange 2, and with key, workpiece is positioned on locating flange 2, rotate the cursor 10 on eccentric cam 6, due to pull bar 7 one end and pressing plate 3 hinged, the other end and eccentric cam 6 are rotationally connected, when eccentric cam 6 and end cap 5 contact position go to the large side of eccentric throw by the side that eccentric throw is little, eccentric cam 6 drives pull bar 7 to move, simultaneously, pull bar 7 pulls pressing plate 3, arm-tie moves down in leading of lead 8, thus pressing plate 3 by Work-sheet pressing on locating flange 2, so far complete the clamping of workpiece.Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
