The specific embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in further detail:
A kind of integrated positioning clamping device is characterized in that it comprises the axis of cone 1, the adjusting nut 2 that is loaded on the axis of cone 1 front end and locatees by backing pin, be fixed in the fixedly cone 3 of the axis of cone 1 by limit screw, be bolted in the fixedly anti-rotation pin 4 of cone 3, anti-rotation pin 4 aimed at by gathering sill and an end is loaded on the fixedly two-way spring 5 that rises of cone 3 conical surfaces, by pack into the activity cone 6 of the axis of cone 1 of feather key 12, be loaded on the spring 7 on the axis of cone 1, be loaded on the centering disk 8 of spring 7 rear ends, back-up ring 9, the fixing primary nut 10 of back-up ring 9, be fixed in the retaining bits cover 11 in centering disk 8 outsides by screw, feather key 12, be threadedly connected to the handle 13 of adjusting nut 2.
As shown in Figure 1, at first adjusting nut 2 is set in the front end of the axis of cone 1, loading onto backing pin positions adjusting nut 2, fixedly cone 3 is packed into from the right-hand member of the axis of cone 1 and is made it to be close to adjusting nut 2, be fixed on the axis of cone 1 with limit screw, after anti-rotation pin 4 is bolted in fixedly cone 3, the two-way gathering sill that rises by spring 5 is aimed at anti-rotation pin 4, make the left conical surface of the two-way spring 5 that rises the fixedly conical surface of cone 3 of fitting, on the axis of cone 1, load onto feather key 12, activity cone 6 is packed into from the right-hand member of the axis of cone 1, by feather key 12 four threaded boss of activity cone 6 left ends are passed fixedly that corresponding four mounting holes are connected with adjusting nut 2 external screw threads on the cone 3, the conical surface of the right conical surface of the two-way spring 5 that rises and activity cone 6 is fitted at this moment, and 2 of adjusting nuts rotate, and rotates adjusting nut 2 activity cone 6 is moved axially.
Then, spring 7, centering disk 8, back-up ring 9, primary nut 10 are packed into from the right-hand member of the axis of cone 1 successively, tighten primary nut 10, primary nut 10 imposes on the certain precompression of spring 7 by back-up ring 9 and centering disk 8, and the pressure of spring 7 can be selected or adjust at its front end increase and decrease packing ring by different length.
At last, will keep off bits cover 11 and be screwed in centering disk 8 outsides, handle 13 is threadedly connected to adjusting nut 2, thereby constitutes the utility model.
The course of work
The axis of cone is packed in the taper hole of spindle of numerical control lathe and is strained with long bolt, rotate adjusting nut, make the activity cone axis to moving right, the two-way spring that rises is in relaxation state, cylindrical shape thin-wall workpiece one end is inserted in the integrated positioning clamping device, and the boss of thin-wall workpiece inwall contacts the little conical surface of centering disk outer all the time.Because centering disk is subjected to the precompressed effect of spring, the right side that withstand thin-wall workpiece by the tail stock thimble this moment, make the left side of thin-wall workpiece be close to the fixedly step surface of cone, by handle rotation adjusting nut, make the activity cone axis to being moved to the left and the two-way spring that rises of tensioner, after the two-way spring that rises tightens up thin-wall workpiece, the tail stock thimble is withdrawed from.This moment thin-wall workpiece front end by the two-way spring clamping and positioning that rises, the rear end is by the centering disk aiding support and axially feel relieved, between centering disk and the back-up ring through having certain interval behind the tail stock thimble roof pressure.After thin-wall workpiece machines, only need unclamp adjusting nut when unloading, the activity cone axis is to moving right and unclamp the two-way spring that rises, and thin-wall workpiece can be by the elastic force of spring, and the conelet face by the centering disk outer promotes workpiece inwall boss and withdraws from automatically.
Below only be preferred embodiment of the present utility model, according to above-mentioned design, those skilled in the art also can make various changes and conversion to this.For example: according to boss on the size change activity cone of clamping force and fixing corresponding mounting hole quantity and according to the fixing size of cone, activity cone, centering disk of the different tube diameters conversion of cylindrical shape thin-wall workpiece on the cone, similar this change and conversion all belong to essence of the present utility model.
