Abstract
The utility model relates to a positioning clamp for processing a strippable gasket of a helicopter, and belongs to the technology of tooling design. The positioning clamp comprises a bottom plate (1), two positioning pins (3) and a gland (4), wherein the bottom plate (1) is a rectangular hexahedron, and the two positioning pins (3) are perpendicularly installed on the upper surface of the bottom plate (1). The center distance between the two positioning pins (3) is equal to the center distance between two opposite-angle positioning holes of four positioning holes on the strippable gasket (5) to be processed; the plane shape and the size of the gland (4) are the same with the plane shape and the size of the strippable gasket (5) to be processed; two pin holes are arranged on the gland (4); and the positions and the sizes of the pin holes are the same with the positions and the sizes of the two opposite-angle positioning holes of the four positioning holes on the strippable gasket (5) to be processed. The positioning clamp is capable of simultaneously processing a plurality of the strippable gaskets, solving the difficult problem that the strippable gaskets are difficult to be compressed tightly, improving processing quality, simplifying processing procedures, shortening workpiece preparing time before processing, increasing use ratio and production efficiency of a machine tool, and reducing processing cost.
Description
Technical field
The utility model belongs to the frock designing technique, relates to a kind of positioning fixture of processing the peelable pad of helicopter.
Background technology
Producing slight error when Helicopter System spare and finished parts assembling need use the peelable pad adjustment of composite to reduce the rigging error value.A kind of structure of peelable pad is referring to Fig. 1, and its flat shape is a rectangle, and 4 angle arc transition have the locating hole of 4 rectangular arrangements on peelable pad.When the appearance and size of the peelable pad of processing, be to adopt the Digit Control Machine Tool single-piece work at present, add and be difficult to man-hour compress, easily aliquation has a strong impact on crudy, needs the pincers worker polishing after digital control processing is finished, before the processing workpiece time long, the utilization rate and the production efficiency of lathe are low, the processing cost height.
Summary of the invention
The purpose of this utility model is: propose a kind of positioning fixture that can process many peelable pads simultaneously, the difficult problem so that solution is difficult to compress improves crudy, simplify procedure, shorten before the processing workpiece time, improve the utilization rate and the production efficiency of lathe, cut down finished cost.
The technical solution of the utility model is: process the positioning fixture of peelable pad, it is characterized in that, it is made up of base plate, two alignment pins and gland; Base plate is a rectangular hexahedron, the pressing plate groove is arranged on the side of base plate, the upper surface of base plate is the clamping district, in the clamping district, be vertically installed with 2 alignment pins, the locating hole matched in clearance of the external diameter of alignment pin and processed peelable pad, the centre-to-centre spacing of 2 alignment pins equals on the processed peelable pad centre-to-centre spacing of two locating holes in diagonal angle in 4 locating holes, the flat shape of gland is identical with processed peelable pad with size, two pin-and-holes are arranged on the gland, on their position and size and the processed peelable pad in 4 locating holes two locating holes in diagonal angle corresponding identical, gland covers on processed peelable pad, and 2 alignment pins, two locating holes from the gland respectively pass.
The utility model has the advantages that: can process a plurality of peelable pads simultaneously, be fit to batch product demand, solved a difficult problem that is difficult to compress, problem such as easy aliquation when having avoided digital control processing, improve crudy, simplified procedure, shortened workpiece time before the processing, improve the utilization rate and the production efficiency of lathe, reduced processing cost.Evidence adopts the utility model that the utilization rate of lathe and production efficiency have been improved more than 2 times.
Description of drawings
Fig. 1 is the structural representation of the peelable pad of a kind of helicopter.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 2, process the positioning fixture of peelable pad, it is characterized in that it is made up of base plate 1, two alignment pins 3 and gland 4; Base plate 1 is a rectangular hexahedron, pressing plate groove 2 is arranged on the side of base plate 1, the upper surface of base plate 1 is the clamping district, in the clamping district, be vertically installed with 2 alignment pins 3, the locating hole matched in clearance of the external diameter of alignment pin 3 and processed peelable pad 5, the centre-to-centre spacing of 2 alignment pins 3 equals on the processed peelable pad 5 centre-to-centre spacing of two locating holes in diagonal angle in 4 locating holes, the flat shape of gland 4 and size are identical with processed peelable pad 5, two pin-and-holes are arranged on the gland 4, on their position and size and the processed peelable pad 5 in 4 locating holes two locating holes in diagonal angle corresponding identical, gland 4 covers on processed peelable pad 5, and 2 alignment pins 3, two locating holes from the gland 4 respectively pass.
Using method of the present utility model is: base plate 1 is fixed on the platen, clamping platen groove 2 behind the centering, to process processed peelable pad 5 blanks of locating hole is placed on the base plate 1,2 alignment pins 3 on the base plate 1 pierce on peelable pad 5 blanks in 2 locating holes, peelable pad 5 blank upper surfaces are put gland 4, can process after suppressing plate, mill out the profile of peelable pad 5.
