Use the utility model discloses the time, can not appear because of leaving the inconvenient problem of the narrow and small appearance of operator working space operation for, because the undercarriage ejector pin evenly distributed that tries one's best when arranging, consequently can be very big satisfy the product undercarriage time the atress even, make the damage of product extremely small, furthermore, the utility model discloses low in manufacturing cost just can reach higher required precision.
Description
Technical field
The utility model relates to a kind of annular products boring grab, for the boring of aircraft parts and components, riveted joint and undercarriage.
Background technology
After the aircraft annular boring of parts and riveting work complete, to need product according to the weight of product and design feature from undercarriage fixture.The undercarriage method of current employing generally has two kinds, gets well and have the product in available axle or hole for opening character, usually adopt the lifting appliance in factory building and be equipped with special instrument indirectly by product from undercarriage fixture; And for the bad product of opening character, then usually need to spend a large amount of human and material resources, financial resources make the smooth undercarriage of product to manufacture and design special instrument.In addition, aircraft annular parts also have following technological difficulties when undercarriage: 1, product leaves operator's narrow space for, inconvenient operation; 2, uneven and easily cause damaged products in undercarriage hand during product undercarriage; 3, general undercarriage structural design manufacturing cost is higher, and the required precision of installing manufacture is higher.
Utility model content
The utility model provides a kind of annular products boring grab, its objective is the part product undercarriage smoothly by using this boring grab to enable semiclosed not easily undercarriage.
A kind of annular products boring grab, comprise frame assembly and be arranged on the worm and gear lifting machine of frame assembly, force bearing disk, connecting rod, dihedral plate, Anchor plate kit, undercarriage push rod, angle seat and jig seat, annular products is placed in jig seat wherein, Anchor plate kit is compressed on the top of annular products, described jig seat and Anchor plate kit adopt several and circular array respectively, and jig seat is provided with drill jig hole and locating hole, described worm and gear lifting machine is as Power output source, force bearing disk is threaded connection the top being installed on worm and gear lifting machine, several connectors are along the circumferential direction provided with at the edge of force bearing disk, connector is connected with one end of connecting rod by hinge axis III, the other end of connecting rod is connected with one end dihedral plate with circular hole a by hinge axis II, one end dihedral plate with slotted hole c is connected by the lower end of hinge axis I with undercarriage push rod, the upper end of undercarriage push rod is through being against on the bottom surface, location of annular products after the circular hole d of angle seat, circular hole b dihedral plate being positioned at corner is then corresponding with the circular hole e on the seat of angle to be connected.
The utility model has following advantage: when 1, using the utility model, there will not be because leaving operator's working space for narrow and small and occur the problem of inconvenient operation; 2, because undercarriage push rod is uniformly distributed when arranging as far as possible, therefore, it is possible to uniform force when meeting product undercarriage greatly, make the damage of product extremely small; 3, the utility model low cost of manufacture and higher required precision can be reached.

Detailed description of the invention
A kind of annular products boring grab as shown in Figure 1, comprise frame assembly 1 and be arranged on the worm and gear lifting machine 3 of frame assembly 1, force bearing disk 4, connecting rod 5, dihedral plate 6, Anchor plate kit 7, undercarriage push rod 8, angle seat 9 and jig seat 10, annular products 14 is placed in jig seat 10 wherein, Anchor plate kit 7 is compressed on the top of annular products 14, described jig seat 10 and Anchor plate kit 7 adopt several and circular array respectively, and jig seat 10 is provided with drill jig hole 16 and locating hole 17, described worm and gear lifting machine 3 is as Power output source, force bearing disk 4 is threaded connection the top being installed on worm and gear lifting machine 3, several connectors 15 are along the circumferential direction provided with at the edge of force bearing disk 4, connector 15 is connected with one end of connecting rod 5 by hinge axis III 13, the other end of connecting rod 5 is connected with one end dihedral plate 6 with circular hole a by hinge axis II 12, one end dihedral plate 6 with slotted hole c is connected by the lower end of hinge axis I 11 with undercarriage push rod 8, the upper end of undercarriage push rod 8 is against on the bottom surface, location of annular products 14 through after the circular hole d of angle the seat 9 and circular hole f of jig seat 10, circular hole b dihedral plate 6 being positioned at corner is then corresponding with the circular hole e on angle seat 9 to be connected.
According to following steps during use:
(a) product orientation: annular products 14 is placed in jig seat 10, the locating hole 17 in jig seat 10 and annular products 14 are all located with latch after locating and aliging, and then compress with Anchor plate kit 7;
B () product is holed: according to the drill jig hole 16 of jig seat 10, annular products 14 is got out bottom outlet and puts in place with reamer fraising, then unclamping Anchor plate kit 7;
(c) product undercarriage: drive worm and gear lifting machine 3 to move downward, thus make to bear dish 4 and move together, then connecting rod 5 promotes dihedral plate 6 and turns clockwise around hinge axis II 12, the undercarriage push rod 8 be attached thereto moves upward along the axially bored line of the circular hole d of angle seat 9, thus is ejected by annular products 14.
The use of the utility model slotted hole c, object eliminates the free degree on oval direction, undercarriage push rod 8 can only be moved in the vertical direction, facilitate annular products 14 to eject from fixture.
The utility model due to the distribution uniform of undercarriage push rod 8, therefore, it is possible to make annular products 14 uniform force preferably.Such as, when worm and gear lifting machine 3 moves downward with the speed of 2mm/s, the linear velocity of generation is parabolic as shown in Figure 9, changes more even.
