Description
Technical field
This utility model relates to a kind of location drill jig, particularly relates to a kind of butterfly valve end cap location drill jig.
Background technology
Butterfly valve accessory has the circular end cap of a kind of sealing, for butterfly valve is sealed, in order to make end cap and butterfly valve fix, it is necessary to hole on end cap, so that end cap can complete assembling by bolt；When end cap is holed, first workpiece is carried out setting-out, then end cap is clamped, in order to have good self-locking performance when ensureing and end cap is clamped, now have employed helical clamping apparatus, namely realize the propelling in clamping face with bolt, workpiece is clamped, owing to bolt has good self-locking performance, so clamping effect is good；But helical clamping apparatus, adopt the characteristic that bolt drives, make clamping stroke excessive, so that clamping process is comparatively time-consuming, and in order to enable clamping force to balance, generally to adopt multiple bolt to drive, so bolt is tightened one by one when clamping workpiece, again workpiece is unclamped one by one during absent-mindedness workpiece so that clamping process complexity is tediously long.
Utility model content
This utility model is intended to provide a kind of butterfly valve end cap location drill jig, to simplify the bore process of butterfly valve end cap.
Base case butterfly valve end cap of the present utility model location drill jig, including base, clamping section and drill jig；Described clamping section includes drive block, first connecting rod, second connecting rod, supporting rod and locating ring；Described drive block is hinged on described base, and is fixedly connected with handle on drive block；Described supporting rod is slidably connected on base；One end of first connecting rod is hinged with drive block, the other end of first connecting rod is hinged with one end of second connecting rod, the other end of second connecting rod is hinged with the lower end of clamping bar, second connecting rod is additionally provided with bar hole, the pin of the bar hole being provided through on second connecting rod on described base, is hinged on second connecting rod on base；Described locating ring is fixedly connected on supporting rod upper end, and locating ring be provided centrally with location taper hole；Described drill jig is arranged on above locating ring, and drill jig is provided with collared hole；And base is also provided with being positioned at the shotpin of drive block right.
Lower pressure handle can make supporting rod move up, workpiece is realized pressuring action, owing to workpiece is round piece, so locating ring is while compressing workpiece, owing to positioning the effect of taper hole, the position of workpiece being had relatively positive interaction, namely locating ring is in the process of workpiece pressing, workpiece will be coaxial gradually with location taper hole, and workpiece is finally positioned at the center of location taper hole；Allow the collared hole coordinated on drill jig, the location drilling to workpiece can be realized.Under press in handle process, when the pin joint conllinear of two pin joints and drive block and the base of first connecting rod, supporting rod is made to have maximum chucking power, also the power between drive block and first connecting rod is made to reach balance, so the shotpin arranged can by spacing for drive block in this position, thus self-locking property can be had fixture, relax because of vibrations with workpiece；Second connecting rod has leverage, namely has labour-saving effect, can change again the direction of power simultaneously.
Workpiece is placed between drill jig and locating ring, then presses handle down, make drive block rotate, then pass through the transmission of each connecting rod power.Supporting rod is made to move up, by Work-sheet pressing at the center positioning taper hole；Then make the drill bit location taper hole on drill bit alignment drill jig, start drill bit, just can complete location drilling；This base case simplifies the clamping mode to the clamping of butterfly valve end cap, makes again fixture have self-locking performance, so that the bore process of butterfly valve end cap is simplified simultaneously.
Preferred version one, as the further optimization to base case, the upper end of described clamping bar is provided with adpting flange, locating ring and adpting flange and is bolted；This optimization can make locating ring be connected spread unchecked with bolts so that locating ring is readily accessible, favourable with change various sizes of locating ring so that drill jig can be used for the workpiece of different model.
Preferred version two, as the further optimization to preferred version one, described adpting flange is provided above extrusion spring；After this optimization can make workpiece is unclamped clamping, workpiece by workpiece extrusion from the taper hole of location, can be taken out by extrusion spring thus convenient.
Preferred version three, as the further optimization to preferred version one, described adpting flange is provided with the drill bit corresponding to described collared hole by hole, and is provided with gusset on adpting flange；The drill bit of this optimization can prevent at boring procedure by hole, after drill bit drills workpiece, continues feeding and is drilled by adpting flange, adpting flange is provided with gusset and adpting flange can be played booster action.
