In the utility model, preferably, drawing on the dish three pulling claws that are provided with of symmetry at least, thereby can position clamping workpiece, certainly, also can symmetry more pulling claw is set.
In the utility model, preferably, drawing the part between dish and the main shaft pull bar to be nested with the adjustment cover, utilizing and adjust the stroke that cover can be adjusted pulling claw and pulling claw at screw.
In the utility model, preferably, be nested with spherical washer at screw with the part of drawing dish to contact, spherical washer can be regulated and draw dish, makes its adjusting draw the dish self-centering.
In the utility model, preferably, on clamp body, be provided with dust cap, be used for preventing that water and iron filings enter in the machine tool chief axis in working angles, even enter oil cylinder.
In the utility model, preferably, the part of stretching out clamp body at pulling claw is nested with lining, can reduce the friction of pulling claw and clamp body, increases the service life of anchor clamps.
In the utility model, preferably, simultaneously be provided with the groove that is used for place work piece, on clamp body and groove that workpiece contacts, be provided with positioning sleeve, thereby increase the service life of anchor clamps at clamp body.
In the utility model, preferably, on clamp body, be provided with the lubricating cup that is used for adding lubricating fluid to pulling claw.
In the utility model, preferably, on the pulling claw circumference, have spiral oil groove.
In the utility model, preferably, on clamp body, be provided with the holding screw that cooperates with the above oil groove of pulling claw.On the pulling claw circumference, have spiral oil groove, the benefit of doing like this is: refuel to pulling claw by lubricating cup on the one hand, the power of reducing friction, increase the service life of pulling claw, holding screw is stuck in the pulling claw oil groove on the other hand, and pulling claw is in carrying out the axially-movable process, also with rotatablely moving like this, be convenient to work-handling, save the lay day of workpiece.
Beneficial effect: the beneficial effects of the utility model are: the first, simple in structure, reliable.The second, come the Design Orientation cover according to part different location benchmark and locating surface.Applied widely, not only guaranteed to have guaranteed the machining accuracy of workpiece productivity ratio, and reduced labor intensity of operating personnel, be fit to part and produce in enormous quantities.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As Fig. 1 and shown in Figure 2, in the automobile-used anchor clamps described in the utility model, it comprises clamp body 3, is provided with the groove 16 that is used for place work piece 18 in clamp body 3 one side, is provided with positioning sleeve 13 on clamp body 3 and groove 16 that workpiece 18 contacts.Be provided with to draw dish 11 and run through at clamp body 3 inner chambers and draw dish 11 the axis of guide 7, draw dish 11 to be connected with main shaft pull bar 2 by screw 9.Drawing the part between dish 11 and the main shaft pull bar 2 to be nested with adjustment cover 8 at screw 9.Be nested with spherical washer 10 at screw 9 with drawing dish 11 parts that contact.Draw dish also to be provided with an end on 11 and stretch out the pulling claw 4 that clamp body 3 is used for clamping workpiece 18.Be provided with three pulling claws 4 what draw symmetry on the dish 11.Be provided with lubricating cup 15 on clamp body 3, lubricating cup 15 communicates with the inner chamber of clamp body 3, is used for adding lubricating fluid to pulling claw 4.On each pulling claw 4 circumference, have spiral oil groove 17, on clamp body 3, be provided with the holding screw 14 that cooperates with each pulling claw 4 the above oil groove 17.The part of stretching out clamp body 3 at pulling claw 4 is nested with lining 1.On clamp body 3, be provided with dust cap 12.Clamp body 3 is fixedlyed connected with the main shaft of lathe by ring flange 6.
The utility model operation principle is: screw 9 draws dish 11, spherical washer 10 with adjusting, adjusts cover 8 and main shaft pull bar 2 and links together, and adjusts the stroke that cover 8 can be adjusted three pulling claws 4.Spherical washer 10 then can be regulated and draw dish 11, makes its self-centering, and the axis of guide 7 is used for preventing to draw the rotation of dish 11.By the pulling of the hydraulic jack on lathe main shaft pull bar 2, axially draw dish 11 by main shaft pull bar 2 more like this, thereby by drawing dish to stir pulling claw 4 with workpiece 18 tensions.On three pulling claw 4 circumference, have spiral oil groove 17, the benefit of doing like this is: refuel for pulling claw 4 by lubricating cup 15 on the one hand, the power of reducing friction, increase the service life of pulling claw 4, holding screw 14 is stuck in the oil groove 17 of pulling claw 4 on the other hand, and pulling claw 4 is in carrying out the axially-movable process, also with rotatablely moving like this, be convenient to work-handling, save the lay day of workpiece.In these automobile-used anchor clamps, clamp body 3 adds the more complicated in man-hour, and in order to increase its service life, the part of stretching out clamp body 3 at pulling claw 4 is nested with lining 1, is provided with positioning sleeve 13 on the groove 16 that clamp body 3 contacts with workpiece.Lining 1 and positioning sleeve 13 all belong to consumable accessory, allow to change.Dust cap 12 is used for preventing that water and iron filings enter in the machine tool chief axis in working angles, even enters oil cylinder.
