Technical field

The utility model is related to gas turbine technology field, is used to clamp gas-turbine combustion chamber end more particularly, to one kind The fixture of lid.

Background technology

In the high-end technical field such as Developing Space aviation, gas turbine is one of which important field of research, wherein The processing of gas turbine is of crucial importance to its quality, therefore when processing the end cover of combustion chamber of gas turbine, the clamping to end cap It is extremely important, it will ensure there is centralized positioning, and existing fixture is typically provided with a centralized positioning in the disc centre of fixture Post, the end cap for having centre bore is placed on centralized positioning post, then clamped, but this kind of fixture can not meet the end in non-stop layer hole Lid, the scope being suitable for is smaller.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is a kind of end cap for clamping different size and can protected The fixture for being used to clamp gas-turbine combustion chamber end cap of card centralized positioning.

To achieve the above object, the scheme of the utility model offer is：One kind is used to clamp gas-turbine combustion chamber end cap Fixture, including clamping fixture seat, the disk and four card articles being fixed on disk that are installed on clamping fixture seat, the disk is provided with four The deep-slotted chip breaker of individual annular spread at equal intervals makes card article in sliding and card article is locked on disk on deep-slotted chip breaker by bolt, And link slot is provided with the inside of the deep-slotted chip breaker for further fixing strip；The card article is provided with sliding groove simultaneously along its length There is claw in being slided on sliding groove, the sliding groove is built-in with the downside of the screw body of connection claw, the screw body and connected There is the bevel pinion that vertical direction is set, bevel pinion described in four is meshed with horizontally arranged bevel gear wheel respectively to be made greatly Bevel gear drives four small bevel gear crop rotations to move clockwise or counterclockwise simultaneously, the driving motor that the bevel gear wheel connection is preset with For driving bevel gear wheel to move by driving motor.

Further, the bevel gear wheel diameter is more than bevel pinion.

Further, being connected with rotary shaft on the downside of the clamping fixture seat makes rotary shaft drive fixture to seat, disk and card article simultaneously Rotation.

This programme has the beneficial effect that：Fixture is suitable for the end cap of different size, and this programme is made by being provided with deep-slotted chip breaker Card article can be in sliding, so that the swingable certain angle of card article, wherein by setting link slot and being consolidated using bolt on deep-slotted chip breaker Surely further card article can be anchored on disk, and drives four bevel pinions simultaneously by bevel gear wheel, make four bevel pinions Counterclockwise or clockwise movement is carried out simultaneously, the opening or closure of claw just can be driven simultaneously, it is ensured that the clamping of end cap does not go out Existing deviation, compared with having center fixed column on traditional disk, the fixture of this programme can clamp centre bore or not have centre bore End cap, it is applied widely, it is also ensured that the centralized positioning of fixture.

Brief description of the drawings

Fig. 3 is the top view of bevel gear wheel of the present utility model.

Wherein, 1 is clamping fixture seat, and 2 be disk, and 21 be deep-slotted chip breaker, and 22 be link slot, and 3 be card article, and 31 be sliding groove, and 32 are Claw, 33 be screw body, and 341 be bevel pinion, and 342 be bevel gear wheel, and 35 be driving motor, and 4 be rotary shaft.

Embodiment

With reference to specific embodiment, the utility model is described in further detail：

Referring to shown in accompanying drawing 1 to accompanying drawing 3, a kind of fixture for being used to clamp gas-turbine combustion chamber end cap, including clamping fixture seat 1st, the card article 3 that the disk 2 being installed on clamping fixture seat 1 and four are fixed on disk 2, disk is provided with four annular spreads at equal intervals Deep-slotted chip breaker 21 make card article 3 in sliding and card article 3 is locked on disk 2, and in arc on deep-slotted chip breaker 21 by bolt The inner side of groove 21, which is provided with link slot 22, is used for further fixing strip, specifically, and an inner side of deep-slotted chip breaker 21 is provided with a link slot 22, the shape of link slot 22 is also arc, and link slot 22 should have four relatively；Card article 3 is provided with sliding groove 31 along its length And have claw 32 in slip on sliding groove 31（Strip structure or L-shaped structure that claw 32 can be set for vertical direction）, and slide Groove 31 is built-in with the screw body 33 of connection claw 32, and the downside of screw body 33 is connected with the bevel pinion of vertical direction setting 341, four bevel pinions 341 are meshed with horizontally arranged bevel gear wheel 342 respectively makes bevel gear wheel 342 while driving four Bevel pinion 341 is moved clockwise or counterclockwise, and the connection driving motor 35 of bevel gear wheel 342 is used to drive by driving motor 35 Dynamic bevel gear wheel 342 is moved.

The clamping process of the present embodiment：Gas-turbine combustion chamber end cap is placed on the center of disk 2 first, then started Driving motor 35, makes driving motor 35 drive bevel gear wheel 342 to turn clockwise, so as to drive four bevel pinions 341 simultaneously Rotated along same clockwise, so that drive screw mechanism 33 works, four claws 32 are moved to clamping end cap to end cap simultaneously, Stop driving motor 35, it is ensured that after claw clamping end cap, the centralized positioning of end cap is not in deviation；When processing end cap Afterwards, driving motor 35 is again started up, driving motor 35 is driven the rotate counterclockwise of bevel gear wheel 342, so as to drive four conelets Gear 341 is rotated along same clockwise simultaneously, so that drive screw mechanism 33 is worked, four claws 32 are separated with end cap simultaneously And initial position is back to, claw 32 is unclamped end cap, then stop driving motor 35；And during processing end cap, rotate Axle 4, which is rotated, makes clamping fixture seat 1, the card article 3 of disk 2 and four rotate simultaneously.
