Abstract
The utility model provides a milling fixture combining positioning and clamping. Positioning benchmarks can be reasonably selected, and uniformity of machining dimensions B and t is ensured. Besides, the position of a movable pressing plate 5 is automatically adjusted according to difference of the dimensions of workpieces 3 and the positions of recesses, the problem of the influence of large dimensional change of aluminum profile blanks on clamping is effectively solved, and effects are remarkable as proved in field use.
Description
Technical field
The present invention relates to a kind of aviation part processing device, relate in particular to a kind of compound positioning and clamping fraise jig.
Background technology
At present, the HB2-24 that the state key model aircraft is selected for use～29 series " extrudate hinge " product adopts the aluminum alloy extrusion section bar blank to process; Main processing work is the sagging position of flute profile that the system of milling is of a size of t; As shown in Figure 1, and flute profile position and the bottom surface A of processing be 60 ° of angles, because the own each several part dimensional tolerance of section bar (like size S) greatly; Uniformity is bad, and certain difficulty is caused in the clamping location.
Summary of the invention
The object of the invention: a kind of compound positioning and clamping fraise jig is provided, can the choose reasonable positioning reference, guarantee the uniformity of processing dimension B, t, solve profile size simultaneously and change greatly to the clamping location influence.
The purpose of the invention is to realize through following technical scheme: a kind of compound positioning and clamping fraise jig; It is characterized in that: installing and locating seat 2 on fixed nip 1; Positioning seat is designed with 60 ° of inclined-planes, and the bottom surface A applying with workpiece 3 realizes the positioning action to bottom surface A; Positioning seat 2 tops are provided with the stopper slot to the workpiece top, guarantee that the machining benchmark of size B and design basis are unified; Compress mainly on movable clamp port 4 and realize, movable holddown 5 is installed on movable clamp port 4, can on movable clamp port 4, slide up and down, with the workpiece contact site be 60 ° of inclined-planes, mainly rely on this inclined-plane and protruding footpath portion 10 workpiece pressings 3.
The advantage of the invention is: can adjust the position of movable pressing board 5 automatically according to the difference of workpiece 3 size S and recessed footpath portion 11 positions, efficiently solve the problem of the change in size considerable influence clamping of aluminium section bar blank, use checking through on-the-spot, effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model workpiece.
Fig. 2 is the structural representation of the compound positioning and clamping fraise jig of the utility model.
The specific embodiment
The main processing work of the utility model workpiece is the sagging position of flute profile that the system of milling is of a size of t, and as shown in Figure 1, the flute profile position of processing and bottom surface A are 60 ° of angles, processing dimension B, t unanimity, and S is the end size of workpiece.
Fig. 2 is the structural representation of the compound positioning and clamping fraise jig of the utility model, and wherein 1 is fixed nip, the 2nd, positioning seat, the 3rd, workpiece, the 4th, movable clamp port, the 5th, movable holddown, the 6th, supplemental support portion, the 7th, leading screw seat, the 8th, leading screw, the 9th, base, the 10th, protruding footpath portion, the 11st, recessed footpath portion; Installing and locating seat 2 on the fixed nip 1 of the compound positioning and clamping fraise jig of the utility model, positioning seat is designed with 60 ° of inclined-planes, fits with the bottom surface A of workpiece 3, realizes the positioning action to bottom surface A; Positioning seat 2 tops are provided with the stopper slot to the workpiece top, guarantee that the machining benchmark of size B and design basis are unified; Compress mainly on movable clamp port 4 and realize, movable holddown 5 is installed on movable clamp port 4, can on movable clamp port 4, slide up and down, with the workpiece contact site be 60 ° of inclined-planes, mainly rely on this inclined-plane and protruding footpath portion 10 workpiece pressings 3.
During process operation, at first workpiece 3 is placed on the positioning seat 2, the stopper slot that is provided with the workpiece top with positioning seat 2 tops is close to; Turn leading screw 8 makes movable clamp port 4 promote movable holddown 5 and presses to workpiece 3, when the inclined-plane of movable holddown 5 contacts with workpiece 3; Under the effect on inclined-plane, movable holddown 5 can be along rising on workpiece 3 inclined-planes, contacts until the recessed footpath of the protruding footpath of movable holddown 5 one 10 and workpiece 3 one 11; Movable holddown 5 no longer rises, and realizes the effect of workpiece pressing.
Claims (2)
