Abstract
The invention discloses a diameter-adjustable revolution body centering and clamping device. The diameter-adjustable revolution body centering and clamping device comprises a hollow cylindrical disc body and a workpiece centering mechanism, wherein the disc body is driven by a machine and comprises an upper half ring and a lower half ring, revolution shafts are arranged at the joints of the upper half ring and the lower half ring, and the upper half ring can turn backwards around the revolution shafts. The portions, corresponding to the revolution shafts, of positioning pins are respectively provided with a clamping bolt and a clamping nut, wherein the upper half ring and the lower half ring can be fixed still through the clamping bolts and the clamping nuts. An aligning screw which is arranged in the circumferential direction of the disc body and can make the center of a workpiece and the machine revolution center coincide serves as the workpiece centering mechanism, wherein a set screw preventing the position of the aligning screw from being changed is arranged on the aligning screw. The lower half ring and an output shaft of a machine are fixed through a transition disc. The diameter-adjustable revolution body centering and clamping device is simple in structure, convenient to use and capable of effectively improving machining efficiency.
Description
Technical field
The present invention relates to mechanical field, relate in particular to the adjustable revolving body centering and clamping apparatus of a kind of diameter.
Background technology
Revolving parts conventionally need to be used fixture when in machining, the center of workpiece and the centre of gyration of machine are overlapped and clamp after could start processing.When the location of workpiece clamping area dimensions changes, wish that fixture has adjustment function.A most frequently used class fixture is scroll chuck, can allow workpiece self-centering clamping, and can adjust in the larger context size.
The shortcoming of scroll chuck is: in order to make reliable clamping, conventionally need three pawls respectively to screw once respectively, this certainly will affect efficiency.When three-jaw opening hour, workpiece need to axially be sent between three-jaw; When three-jaw opening is enough large, workpiece can radially be sent between three-jaw, but the time increase that three-jaw screws in and screws out is a lot, has affected efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of diameter adjustable revolving body centering and clamping apparatus, it is simple in structure, easy to use, can effectively improve working (machining) efficiency.
To achieve these goals, the technical solution used in the present invention is: the revolving body centering and clamping apparatus that a kind of diameter is adjustable, comprise the disk body and the workpiece centering machine that are hollow cylinder, disk body is driven by machine, described disk body comprises semi-ring and lower semi-ring, the junction of upper semi-ring and lower semi-ring arranges single-revolution axle, and upper semi-ring can be turned in wraparound rotating shaft; The position that described disk body is corresponding with gyroaxis arranges an alignment pin, is provided with and upper semi-ring and lower semi-ring can be linked together and make the fixed fishbolt of workpiece and binding nut on alignment pin; Described workpiece centering machine, for the aligning screw along circumferential the made workpiece centre arranging of disk body and the coincidence of the machine centre of gyration, is provided with the holding screw that prevents its shift in position on aligning screw; Described lower semi-ring is fixed by transition disc and machine output shaft.
Lower semi-ring is located on transition disc by two straight pins.
Between lower semi-ring and transition disc, by three attachment screws, fix.
The beneficial effect that the present invention brings is: by the adjustable revolving body centering and clamping apparatus of diameter, can be to a collection of workpiece centering in the situation that adjusting once, and Quick-clamped and unclamping.It is detachable workpiece that Quick-clamped and unclamping is embodied in that binding nut only need to unscrew in right amount.Because upper semi-ring can forward the rear portion of lower semi-ring to, so workpiece can radially directly be put on lower semi-ring, do not need axially to send into and send, easy to loading and unloading.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, the revolving body centering and clamping apparatus that a kind of diameter is adjustable, comprise the disk body and workpiece 12 centering machines that are hollow cylinder, disk body is driven by machine, described disk body comprises semi-ring 5 and lower semi-ring 8, the junction of upper semi-ring 5 and lower semi-ring 8 is provided with gyroaxis 22, and upper semi-ring 5 can be turned in wraparound rotating shaft 22; The position that described disk body is corresponding with gyroaxis 22 arranges an alignment pin 21, is provided with and upper semi-ring 5 and lower semi-ring 8 can be linked together and make the fixed fishbolt 3 of workpiece 12 and binding nut 4 on centring pin 21; Described workpiece centering machine, for the aligning screw 6 along circumferential made workpiece 12 centers that arrange of disk body and the coincidence of the machine centre of gyration, is provided with the holding screw 7 that prevents its shift in position on aligning screw 6; Described lower semi-ring 8 is fixing with machine output shaft 9 by transition disc 11, fixing through holding screw I 10 between machine output shaft 9 and transition disc 11.Lower semi-ring 8, is fixed by three attachment screws 13 between lower semi-ring 8 and transition disc 11 in transition disc 11 location by two straight pins 1.
Adjust the position of three aligning screws 6, can make the centre of gyration of workpiece 12 center and machine overlap.After adjust the position of aligning screw 6, with three holding screws 7, clamp, prevent its position change.After adjusting, upper semi-ring 5 is upwards turned over out by gyroaxis 22, workpiece 12 is put into, upper semi-ring 5 is resetted.Fishbolt 3, around alignment pin 21 pull-ups, enters in the open slot of semi-ring 5, and binding nut 4 screws, and the centering that has completed workpiece 12 clamps.After workpiece 12 machines, unscrew binding nut 4, fishbolt 3, with binding nut 4, is thrown off with upper semi-ring 5 fast, can start next operation cycle, until a collection of workpiece completion of processing.When diameter of work changes, readjust the position of three aligning screws 6.With a collection of workpiece, only need to adjust once, can increase work efficiency.
