Abstract
The utility model discloses a self-compensating and positioning device of an assembly fixture, which comprises a positioning lining (1), and the external diameter of the positioning lining (1) is matched with a positioning fabrication hole on an assembly part to be positioned. The device is characterized in that the inner hole of the positioning lining (1) is made into a long round hole; a step lining (2) is arranged in the long round hole; a pair of threaded holes are symmetrically and radially formed on the positioning lining (1) in the length direction of the long round hole; adjusting screw pins (3) and (4) are respectively arranged in the threaded holes; and springs (5) and (6) are mounted on the adjusting screw pins. The step lining (2) can be pushed to slide in the long round hole when the positioning position of the fabrication hole on the assembly part does not correspond to that of the fabrication hole on the assembly fixture, so as to improve the compensation amount and quality of the positioning of the fixture. The step lining (2) can restore to the initial state under the force of the springs when the part to be delivered for loading is taken out, so that the installation speed and accuracy of the fixture is improved.
Description
Technical field
The utility model relates to a kind of assembly jig self compensation positioner, especially relates to the assembly jig self compensation positioner that a kind of hole is the location.
Background technology
In the aviation manufacturing at home and abroad, assembling is that a large amount of parts is positioned assembling at the type frame, in the type frame positioner, send the dress part be with two fabrication holes on the part serve as the location benchmark, the structure of positioner is as setting element with lining, its structure is on the part position of needs location support component to be installed, and installing on support component needs the lining of locating element size to come locating element, and what its bush hole was all selected for use is circular hole.Owing to send two process Installation holes adorning on the part during fabrication because tolerance build-up, when on the type frame, the circular hole locator being installed, even installing, the type frame meets the requirement of frock drawing fully, also can't solve the problem of part tolerance accumulation, adopt diamond pattern finger setting method, though this method can solve the compensation problem of tolerance build-up, because its structure is the line compensation to two fabrication holes, the error of the airborne vehicle profile behind the location is quite big, the installation of locator had also brought sizable alignment error (about 0.2～0.3) when the simultaneous type frame was installed, both reach 0.5 by deviation accumulation, during location and installation, all be to remedy when part can't be located with the size that reduces alignment pin, promptly time-consuming, influence product quality again.
Summary of the invention:
The technical problems to be solved in the utility model is to provide the assembly jig self compensation positioner of a kind of hole system location, can the compensate for process installing hole and the accumulated error made of type frame locator.
For solving the problems of the technologies described above, the utility model provides a kind of assembly jig self compensation positioner, comprise positioning adapter, external diameter of positioning adapter cooperates with positioning process hole on the Assembly part that needs the location, it is characterized in that: described positioning adapter endoporus is made slotted hole, in slotted hole, be provided with a step lining (, positioning adapter upper edge slotted hole length direction radial symmetric is provided with a pair of screwed hole, the adjusting spiral pin is set respectively in the screwed hole, on the adjusting spiral pin, spring is installed, when the fabrication hole on the Assembly part and assembly jig fabrication hole position location are inharmonious, can promote the step lining and in slotted hole, slide.The plane is made in the big step two sides of described step lining, the rectangular recess matched in clearance of its width and positioning adapter.
The utility model has following good effect than prior art.A kind of assembly jig self compensation positioner of the present utility model, increased the slotted hole in the fixed cover, the setting of slotted hole is in order to solve the tolerance build-up of numerical control fabrication hole, in oval, put into a step lining, utilize the slip of step lining in slotted hole to come the tolerance build-up of fabrication hole is compensated.Compare with original structure, the compensation rate and the alignment quality of the frame of raising type greatly location, step lining in the slotted hole grinds two planes on the work cylindrical simultaneously, match with rectangular recess inwall on the slotted hole in this two plane, to guarantee the position accuracy of its slip, the slotted hole length direction is installed two springs in step lining upper edge, and this circular hole lining can return to original state after part takes out, and has improved the installation speed and the accuracy of type frame.

The specific embodiment
Below in conjunction with embodiment the utility model is further described.
Fig. 1, Fig. 2 is a kind of assembly jig self compensation positioner of the present utility model, comprise positioning adapter 1, external diameter of positioning adapter 1 cooperates with positioning process hole on the Assembly part that needs the location, it is characterized in that: described positioning adapter 1 endoporus is made slotted hole, a step lining 2 is set in slotted hole, positioning adapter 1 upper edge slotted hole length direction radial symmetric is provided with a pair of screwed hole, be provided with respectively in the screwed hole and regulate spiral pin 3 and 4, on the adjusting spiral pin, spring 5 and 6 are installed, when the fabrication hole on the Assembly part and assembly jig fabrication hole position location are inharmonious, can promote step lining 2 and in slotted hole, slide.Described positioning adapter 1 one end faces are made rectangular recess, and the plane is made in the big step two sides of described step lining 2, the rectangular recess matched in clearance of its width and positioning adapter 1.
Claims (2)
1. assembly jig self compensation positioner, comprise positioning adapter (1), external diameter of positioning adapter (1) cooperates with positioning process hole on the Assembly part that needs the location, it is characterized in that: described positioning adapter (1) endoporus is made slotted hole, a step lining (2) is set in slotted hole, positioning adapter (1) upper edge slotted hole length direction radial symmetric is provided with a pair of screwed hole, be provided with respectively in the screwed hole and regulate spiral pin (3) and (4), on the adjusting spiral pin, spring (5) and (6) are installed, when the fabrication hole on the Assembly part and assembly jig fabrication hole position location are inharmonious, can promote step lining (2) and in slotted hole, slide.
2. a kind of assembly jig self compensation positioner according to claim 1, it is characterized in that: described positioning adapter (1) one end face is made rectangular recess, the plane is made in the big step two sides of described step lining (2), the rectangular recess matched in clearance of its width and positioning adapter (1).
