Description
One. affiliated technical field:
The utility model relates to a kind of eccentric fixture, particularly relates to a kind of eccentric adjustable elastic anchor clamps.
Two. background technology:
The processing of eccentric element is the difficult point in the machining, generally adopts three-jaw, chuck at present for the processing that resembles eccentric parts such as capacity eccentric bearing, cam, processes on machine tool.Because the clamping workpiece difficulty, not only working (machining) efficiency is low, and machining accuracy also is difficult to guarantee, often cause part scrap and processing cost higher, therefore, existing processing method is unsuitable in enormous quantities, high-precision part production.The utility model has solved the problems referred to above by improving design of Clamping Apparatus.
Three. the utility model content:
Overcome the technological deficiency in the existing eccentric element processing, provide a kind of high reliability, high efficiency, high-precision eccentric adjustable elastic anchor clamps.
The technical solution of the utility model: a kind of eccentric flexible jig, contain transition disc, mounting, back stay, draw dish, T type contiguous block, collet, locating ring, front tension bar are being installed on the mounting and are being installed on nuts and washers on the front tension bar.The radial disbalance adjustable mechanism is arranged between transition disc and the mounting.
Described eccentric adjustable mechanism contains the locating slot on being opened in bottom the mounting along off-centre adjustment direction symmetry transition disc center two alignment pins, edge eccentric adjustment direction mounted thereto, the transition disc upper edge is eccentric adjusts that direction is uniform offers four T type grooves, mounting bottom correspondence is offered four screw holes, and both are fastening by T type piece with bolt.Collet one end is sleeved on the mounting cylindrical step, and both circumferencial directions are by the pin radial location and the compression spring is housed, and the inner conical surface of the other end cooperates with the male cone (strobilus masculinus) at mounting top.Be set with locating ring in the collet outside, locating ring one end is connected on the mounting with nut, and the other end is located as the workpiece to be machined end face.Mounting, collet, locating ring, front tension bar are concentric, and be radially adjustable along alignment pin together with T type piece during adjustment.
Described front tension bar one end runs through through hole and connects with T type piece.T type piece is positioned at and draws dish to adjust direction connects a side with front tension bar T-slot at offset, draws the opposite side thread connection back stay of dish, and back stay directly connects with the lathe oil cylinder.The front and back pull bar moves forward and backward under the oil cylinder effect, by tapering between mounting and the collet and compression spring, makes collet produce axial displacement, thereby causes radially expansion or contraction.
Described collet front portion is many valve structures, and the tapering cone angle that cooperates with mounting is 6 °-12 °.
The beneficial effects of the utility model:
1. the utility model reliable operation is applied widely.Adopt the action of the action control anchor clamps of hydraulic machine oil cylinder to realize the clamping of workpiece and unclamp, it is adjustable to step up power, and the clamping of workpiece is convenient reliable.Adjust relative position between transition disc and the mounting according to different workpiece, access different offsets according to the scale on the transition disc, and change suitable collet, so this utility model is applicable to the batch machining of the disk-like accessory of different offsets.The utility model both can be used for Concentric plate class blank part processing and had gone out desired offset; Can be used for the further fine finishining of eccentric disc class blank part again, only the processing line of offset position on the part need be alignd with mark line on the anchor clamps locating ring during fine finishining gets final product.
2. the utility model positioning accuracy height, the working (machining) efficiency height.Owing to adopt the tapering location between collet and the mounting, the end face that locating ring contacts with workpiece can autogenous grinding on lathe, simultaneously, also can on lathe, further proofread and correct offset after the anchor clamps installation with the standard eccentric work piece, after correction finishes, the screw of fastening adjustment offset just can be processed, and has therefore improved the clamping workpiece positioning accuracy.Since can with the automatic or supporting use of semi-automatic controlling machine, can realize higher working (machining) efficiency, after the popularization, have higher economic and social benefit.
3. the utility model is easy to install, described eccentric adjustable elastic anchor clamps, and collet and locating ring are Replacement Parts, only need get final product according to different workpiece apolegamys.By the tapering of front end and the radial location finger setting of rear end, use Bolt Connection between locating ring and the mounting between collet and the mounting, change very convenient.

Fig. 3 adjustable eccentric anchor clamps B-B direction cutaway view
Fig. 4 adjustable eccentric anchor clamps C is to structural representation
Five. the specific embodiment:
Embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, transition disc 3 and the mounting 13 that connects with it, radially adjustable by the locating slot that is loaded on the alignment pin 4,15 on the transition disc 3 and be opened on the mounting 13 between the two, realize the offset adjustment.On the one end suit of collet 8 and the column type step of mounting 13, both circumferencial direction with three pin 14 radial locations and be equipped with three the compression springs 6, the inner conical surface of the other end cooperates with the male cone (strobilus masculinus) of mounting 13.Be set with in the outside of collet 8 locating ring 7 usefulness bolts 5 be connected in the seat add on 13, be used for the axial location of workpiece to be machined 9.Mounting 13 cores are set with front tension bar 12, and front tension bar one end is by T type piece 16 and draw dish 2 to connect with back stay 1, draw to coil 2 and offer T-slot in offset adjustment direction and front tension bar connection place.Back stay 1 connects with the lathe oil cylinder, at front tension bar 12 other ends nut 10 and packing ring 11 is installed.Being engraved in mark line 18 on the locating ring is used for aliging with the technology mark line of offset on the workpiece to be machined 9.When adjusting offset, unload locating ring 7, unclamp nut 10 and 4 screws 17 and T type piece 20, adjust the radial position of mounting 13 and transition disc 3, driving collet 8, front tension bar 12, T type piece 16, T type piece 20, nut 10 and packing ring 11 moves radially along the locating slot direction together, by being engraved on the size of the graduation mark 21 definite offsets on the transition disc 3, and four T type grooves 19 by offering on the transition disc 3, T type fast 20 and mounting 13 usefulness bolts 17 fastening after, install locating ring 18 again, to the offset correction and to getting final product processing work after the reconditioning of locating ring end face.When under the drive of back stay 1 at oil cylinder when mobile backward, drawing dish 2 to drive front tension bar 12 by T type piece 16 moves backward together with nut 10 and packing ring 11, collet 8 moves backward and compression spring 6 thereby drive, collet distending and clamping work pieces under the effect of mounting 13 front end taperings and collet 8 inner cones.When back stay 1 moves forward, draw dish 2 to drive front tension bar 12 and move forward together with nut 10 and packing ring 11, collet 8 moves forward under the elastic force effect of spring 6, and collet shrinks and unclamps workpiece.
