Abstract
The utility model belongs to the technology of tooling design and relates to a positioning seat used for machining complex joint parts of a helicopter. The positioning seat consists of a base (1) and a supporting block (2); the base (1) is a rectangular hexahedron; the middle part of the upper surface of the base (1) is provided with the supporting block (2) with an right-angled section; the bottom surface of the supporting block (2), namely the plane in which the inclined edge of the right-angled section is located is connected with the upper surface of the base (1) into a whole; and a long slot (3) which passes through the upper surface and the lower surface of the base (1) and is vertical to the right edge starts from the middle point of the right edge of the supporting block (2). In the utility model, the positioning and clamping problem of the complex part is solved, quick clamping and positioning are realized, the rigidness of part machining system is improved, the shaking phenomenon of cutter is eliminated, and the machining efficiency and the qualified rate of part are improved.
Description
Technical field
The utility model belongs to the frock designing technique, relates to a kind of positioning seat that is used to process the complicated joint part of helicopter.
Background technology
The structure of the complicated joint part of a kind of helicopter is seen Fig. 1, and this joint part connects to form integrated member by a square groove structure, two bearings and a monaural.The opening of square groove structure upwards has a certain degree with vertical plane, and two bearings are positioned at the both sides of square groove structure, and each bearing is the angle bar shape, stretches to the rear of square groove structure.Monaural is positioned at the place ahead, middle part of square groove structure, and monaural stretches to the below of square groove structure simultaneously, and the lower limb of monaural is lower than the bottom surface of bearing.This part shape complexity, clamping difficulty during processing.At present, process this complicated shape part and need adopt the increasing blank, so that add auxiliary plate frame on every side; When processing square groove structure and upper surface of support, owing to below monaural is arranged, be difficult to support, form unsettled processing, whole part system of processing poor rigidity, the handling ease cutter that quivers, working (machining) efficiency is low, and the part qualification rate is low.
Summary of the invention
The purpose of this utility model is: a kind of positioning seat that is used to process the complicated joint part of helicopter is provided, to solve the problem of clamping difficulty, improves the rigidity of part processing system, eliminate the cutter that quivers, improve working (machining) efficiency and part qualification rate.
The technical solution of the utility model is: the positioning seat that is used to process the complicated joint part of helicopter, it is characterized in that, it is made up of base and back-up block, base is a rectangular hexahedron, in the upper surface middle part of base a cross section being arranged is the back-up block of right angled triangle, the bottom surface of back-up block is that the plane at hypotenuse place of right triangular cross-sectional and the upper surface of base are connected to integral body, the length direction of back-up block is vertical with the length direction of base, the right flank of back-up block is that the plane at the long right-angle side place of right triangular cross-sectional is a supporting surface, the upper surface of this supporting surface and base intersects the right hand edge that forms back-up block, from right hand edge, light one perpendicular to this right hand edge, connect the elongated slot of base upper and lower surface, the horizontal cross-section size of elongated slot is greater than the horizontal cross-section size of processed joint part square groove front monaural, when the upper surface of the bottom surface of processed joint part side supports and base is fitted, the square groove bottom surface in the middle of the processed joint part side supports and the supporting surface of back-up block are fitted, and the monaural of processed joint part square groove front inserts in the elongated slot.
The utility model has the advantages that: solved the positioning and clamping difficult problem of complex parts, realized the quick-clamping location; Improve the rigidity of part processing system, eliminated the cutter that quivers, improved working (machining) efficiency and part qualification rate.Evidence, working (machining) efficiency of the present utility model have improved more than 3 times, the part qualification rate from original 50% to be issued to 100%.
Description of drawings
Fig. 1 is the structural representation of the complicated joint part of a kind of helicopter.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 2 and Fig. 3, be used to process the positioning seat of the complicated joint part of helicopter, it is characterized in that, it is made up of base 1 and back-up block 2, base 1 is a rectangular hexahedron, at the upper surface middle part of base 1 back-up block 2 that a cross section is arranged is right angled triangle, the bottom surface of back-up block 2 is that the plane at hypotenuse place of right triangular cross-sectional and the upper surface of base 1 are connected to integral body, the length direction of back-up block 2 is vertical with the length direction of base 1, the right flank of back-up block 2 is that the plane at the long right-angle side place of right triangular cross-sectional is a supporting surface, the upper surface of this supporting surface and base 1 intersects the right hand edge that forms back-up block 2, from right hand edge, light one perpendicular to this right hand edge, connect the elongated slot 3 of base 1 upper and lower surface, the horizontal cross-section size of elongated slot 3 is greater than the horizontal cross-section size of processed joint part square groove front monaural, when the upper surface of the bottom surface of processed joint part side supports and base 1 is fitted, the square groove bottom surface in the middle of the processed joint part side supports and the supporting surface of back-up block 2 are fitted, and the monaural of processed joint part square groove front inserts in the elongated slot 3.
Using method of the present utility model is: at first, process joint part blank two bearing bottom surfaces following monaural part and square groove bottom surface, then, the upset of joint part blank is placed on the positioning seat, with the upper surface of base as locating surface, the two bearing bottom surfaces that the joint part blank has been processed and the upper surface of base are fitted, the square groove bottom surface in the middle of the processed joint part side supports and the supporting surface of back-up block are fitted, the monaural of processed joint part square groove front inserts in the elongated slot, after the joint part blank places, both sides compress with pressing plate, can process the square groove part.
