Abstract
A clamp for processing disc thin-walled parts comprises a flange and a negative-pressure sucker, wherein the negative-pressure sucker is formed by fastening a base plate and a sucker; a cavity is formed between the base plate and the sucker; a plurality of through holes communicated with the cavity are formed on the sucker; a suction hole communicated with the central hole of the flange is arranged on the base plate corresponding to the central hole of the flange; and the flange is fixedly connected with the external side of the base plate. An external vacuum system is connected with the cavity of the negative-pressure sucker to form a vacuum loop. One surface of a workpiece is attached with the sucker when the vacuum loop is connected. Vacuum negative pressure is formed between the workpiece and the sucker, and the workpiece is pressed on the surface of the sucker by atmosphere, so that the workpiece is positioned firmly. Jaws of a three-jaw chuck corresponds to a trough on the negative-pressure sucker. Parts can be ensured to automatically align and center by the jaws. The clamp for processing the disc thin-walled parts has the advantages of high processing precision, simple structure and high production efficiency.
Description
Technical field
The utility model relates to a kind of lathe fine finishining anchor clamps, particularly a kind of anchor clamps that are used for the processing of dish-type thin wall component.
Background technology
In the graphite thermal field that the monocrystalline silicon industry is used, multiple large thin-wall disk-like accessory is arranged, big (500-900mm) thinner thickness (8-15mm) of diameter, and specification requirement is higher, the technological process of producing this part at present is divided into slightly, the finish turning two procedures, rough turn operation is: large-scale graphite raw material is behind a rough turn cylindrical of large-scale lathe and a rough turn end face, with the extended type cutting knife it is downcut, finish turning operation: on universal lathe, use general class (three-jaw, four paws) chuck clamping workpiece, another end face and the endoporus of finish turning workpiece, because the characteristics of universal fixturing, for the big limitation of being processed with of this peculiar part, mainly contain to add and hold distortion, clamping is insecure, process velocity influences machining accuracy and production efficiency slowly, and in the finish turning operation, by (three-jaw, four paws) retained part is owing to the anchor clamps restriction can not be processed, can only handle the raw material that waste is expensive as leftover bits and pieces.
The utility model content
The purpose of this utility model provides a kind of machining accuracy height, simple in structure, a kind of anchor clamps that are used for the processing of dish-type thin wall component of improving crudy and production efficiency.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of anchor clamps that are used for the processing of dish-type thin wall component comprise ring flange and negative pressure sucker in its structure; Described negative pressure sucker is fastened by chassis and sucker and forms, and is provided with cavity between chassis and sucker, offers a plurality of through holes that are communicated with cavity on sucker; On the chassis, be provided with the air entry that is connected with the ring flange centre bore with the corresponding position of ring flange centre bore; The lateral surface on described ring flange and chassis is fixedly connected.
The outer surface of described sucker is provided with the groove of a plurality of concentric annular, is provided with convex tendon in the middle of the adjacent groove.
Described through hole is opened in the groove.
Offer three or four draw-in grooves on the circumference of described negative pressure sucker.
The beneficial effects of the utility model are: owing to adopted the mode of negative pressure of vacuum sucker and chuck combination, guarantee the accurate location of part axial with the negative pressure of vacuum sucker, the claw of scroll chuck is corresponding with the draw-in groove position on the negative pressure sucker, can guarantee the centering of part automatic capturing with claw, and can not cause damage to workpiece, machining accuracy improves, simple in structure, production efficiency raising.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic surface of negative pressure sucker among Fig. 1.
Among the figure, 1, the chassis, 2, sucker, 3, ring flange, 4, air entry, 5, negative pressure sucker, 6, groove, 7, through hole, 8, cavity, 9, convex tendon, 10, draw-in groove.
The specific embodiment
The utility model is a kind of anchor clamps that are used for the processing of dish-type thin wall component, it mainly grasps, adsorbs and locate workpiece by chuck, negative pressure sucker and pumped vacuum systems, has avoided original in the loss of using mechanical chuck anchor clamps defective work piece to cause.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, a kind of anchor clamps that are used for the processing of dish-type thin wall component, adopt the scroll chuck of elongated clamping jaw, scroll chuck connects with negative pressure sucker 5 by ring flange 3, the circumference of negative pressure sucker 5 is provided with three draw-in grooves 10 of 120o at interval, and the claw of scroll chuck is corresponding with draw-in groove 10 positions, and negative pressure sucker 5 is fastened by chassis 1 and sucker 2 and forms, be provided with cavity 8 between chassis 1 and sucker 2, negative pressure sucker 5 connects the formation vacuum loop by air entry 4 and outside pumped vacuum systems.
The outer surface of sucker 2 equidistantly is provided with the groove 6 of the wide concentric annular of 12-18 15mm, 6 of adjacent grooves leave the wide convex tendon of 5-10mm 9, groove 6 dark 5-8mm, groove 6 every interval 120o are provided with 1 through hole 7 and communicate with cavity 8, through hole 7 and adjacent draw-in groove 10 interval 60o are provided with 36-54 through hole 7 altogether.
Operation principle of the present utility model is: as needs processing diameter 500-1000mm, when thickness is the dish-type thin wall component of 3-15mm, the scroll chuck of elongated clamping jaw blocks the automatic capturing centering that workpiece is finished workpiece by flexible adjustment claw, guarantees the axially accurate location of workpiece with negative pressure sucker 5.Plane when vacuum loop is connected after the workpiece roughing and the intimate of sucker 2 are fitted, in the middle of the outer surface of workpiece and sucker 2, form negative pressure of vacuum, this moment, outside atmospheric pressure will be on the firm outer surface that is pressed in sucker 2 of workpiece, thereby realized the firmly accurate location of workpiece.
