The invention can be used for a flexible clamp for processing aircraft skin tools and positioning a workpiece.
Description
Technical field
The present invention relates to flexible positioning pin, be specifically related to the flexible positioning pin on a kind of clamp body of aircraft skin use for machining parts.
Technical background
Covering is the strength member that guarantees the aircraft aerodynamics performance, and the aircraft skin stochastic pattern is different with covering residing position on airframe and present different shapes and specification.Because covering specification, shape, change in size are many, the clamping of workpiece, to adjust shared ratio very high, influenced the raising of working (machining) efficiency.If according to traditional clamping means, will design numerous anchor clamps, and have problems such as bad adaptability, cost increase and management difficulty are big, must adopt flexible fixture to adapt to the requirement of different workpieces, and aircraft skin class part is because size and curvature of curved surface different, position of dowel hole and size are also fixing above it, how to set up accurate localization concerns it is the key that guarantees crudy between workpiece and the anchor clamps.
At present, the alignment pin on the aircraft skin class part clamp all adopts fixing mode, can't adjust its position and angle, causes a kind of anchor clamps can only process one or more workpiece of the same type, causes very big waste.Therefore, a kind of can be according to different, the dowel hole position of surface of the work shape and size and size different, can freely adjust the position and the angle of alignment pin, make that the dowel hole axis overlaps fully on shop bolt and the workpiece, the position can be current active demand to aircraft skin class part processing location by exactly determined flexible positioning pin between workpiece and the clamp body, to guarantee the crudy of workpiece.
Summary of the invention
The purpose of this invention is to provide the flexible positioning pin on a kind of clamp body that is used for the aircraft skin use for machining parts.Move both vertically workbench and horizontal movement motion workbench of dowel device of the present invention, rotary table, one formed, have easy to adjust, precision is high, characteristics such as widely applicable.Among the present invention, the dowel device of being made up of pedestal 4 and shop bolt 3 is fixed on the workbench that moves both vertically by screw, and shop bolt 3 and pedestal 4 are connected by interference fit, can change the size of shop bolt 3 according to the size of workpiece dowel hole; The rotary table of being made up of supporting disk 2, rolling disc 6, set screw 7 and lock screw 5 is fixed on the workbench that moves both vertically by contiguous block 8, by turning set screw 7, can drive rolling disc 6 and fixed thereon 's dowel device rotation, thus adjustable angle of adjusting a pin 3.After having adjusted, can rolling disc 6 be fixed on the supporting disk 2 by lock screw 5; By back-up block 1, movable block 9, micrometer 10, and the workbench that moves both vertically formed of the lock-screw of side be fixed on the horizontal movement workbench by contiguous block 11, by turning micrometer 10, can drive movable block 9 and move in vertical direction, thereby adjust shop bolt 3 position in vertical direction with rotary table.After having adjusted, can movable block 9 be fixed on the back-up block 1 by lock screw; The horizontal movement workbench of being made up of back-up block 14, movable block 12, micrometer 15 and lock-screw 13 can be connected and fixed by relevant apparatus and clamp body, by turning micrometer 15, can drive movable block 12 and move in the horizontal direction, thereby adjust shop bolt 3 position in the horizontal direction with the workbench that moves both vertically.After having adjusted, can movable block 12 be fixed on the back-up block 14 by lock screw 13.Shop bolt 3 can be demarcated by laser tracker in advance with the initial position of clamp body, difference according to different workpieces dowel hole position, can make the axis direction and the dead in line of workpiece dowel hole of shop bolt 3 by the motion of two one dimension workbench and rotary table.The position that shop bolt 3 moves and the angle of rotation can be obtained by the scale on two one dimension workbench and the rotary table, can calculate the particular location of shop bolt 3 in clamp body according to the software that weaves again, this flexible positioning pin generally has 2～3 to be used, thereby can accurately determine the position of workpiece in clamp body.By the present invention have easy to adjust, precision is high, characteristics such as widely applicable, the location when being particularly suitable for the aircraft skin class part processing of different sizes and curved surface, the definite position of setting up between workpiece and the clamp body concerns.
