Description
Technical field
The utility model relates to the turning processing unit (plant), especially relates to a kind of clamp for machining of turning large-diameter thin-walled axle sleeve.
Background technology
Thin-walled axle sleeve in turning processing is because wall approaches self poor rigidity, and is yielding, is unfavorable for the jig clamping.Chinese patent notification number CN201244687Y, date of declaration is on May 27th, 2009, name is called the frock that discloses a kind of annular thin wall part processing in " a kind of annular thin wall part processing special tooling ", mandrel one end is installed in the claw of lathe power chuck, step of other end car and annular thin wall workpiece internal diameter match, workpiece is enclosed within on the step of mandrel cylindrical, core shaft end's cover upper cover plate, and cover plate is fixed by screw and mandrel.Workpiece axial end core pillow block rank restriction, the other end is limited by outer cover plate, like this can turning thin-walled workpiece cylindrical.Bowlder in turning annular thin wall workpiece, other does a mandrel, and the interior circle of mandrel needs car to go out a step and the workpiece cylindrical matches, workpiece is embedded on the interior step of mandrel, core shaft end's cover upper cover plate, cover plate center drilling diameter is bigger than workpiece, and cover plate is connected with mandrel thread.Workpiece axial end core pillow block rank restriction like this, the other end is limited by outer cover plate, can the interior circle of turning annular thin wall workpiece.
Use this anchor clamps to solve because the workpiece wall is thin by distortion of lathe power chuck claw clip and the yielding problem of the processing thin-walled workpiece inside and outside circle of turning.But because workpiece turning inside and outside circle needs the different anchor clamps of a cover separately, and axle sleeve of same machined into needs the secondary clamping, production cost height not only, and also working (machining) efficiency is low.To workpiece is the axial restraint motion, and circumference tangentially is subjected to the effect of lathe tool cutting force, is the frictional force restriction by workpiece and mandrel, the fixing unreliable crudy that influences.
Summary of the invention
Want clamping twice in order to overcome the processing thin-walled axle sleeve inside and outside circle of turning, reservation allowance multiple clip pivots to workpiece and limits insecure defective, reach a clamping thin-walled axle sleeve and get final product the turning inside and outside circle; the thin wall shaft suit clips the purpose solid, that allowance is few, production cost is low, efficient is high, the utility model provides a kind of thin wall shaft cover turning clamp for machining.
The technical solution of the utility model is: a kind of thin wall shaft cover turning clamp for machining, one end of anchor clamps and lathe power chuck claw clip, the other end is connected with the thin wall shaft cover, anchor clamps are disc, the one end is a large cylinder for the small cylinder other end, the connecting portion of small cylinder and large cylinder is a step, and large cylinder is provided with through hole, and the screw that is strained and fixed is set in the through hole.Anchor clamps are connected with lathe power chuck claw, and thin-walled axle sleeve workpiece has been eliminated thin-walled axle sleeve workpiece clamping deformation not by the direct clamping of bed power chuck claw.The anchor clamps end face is connected by the screw that is strained and fixed with thin-walled axle sleeve workpiece end face, and turning thin-walled axle sleeve inside and outside circle only needs clamping once on lathe, and allowance is little, the saving cost, and process procedure is few, has improved production efficiency.Anchor clamps have limited the axial and motion radially of thin-walled axle sleeve workpiece, clamp firmly.
As preferably, on the step surface of the large cylinder of anchor clamps through hole is set, through hole be arranged on that diameter does not wait and with the body concentric circumference of big column on, uniform 8 to 16 through holes on each concentric circumference; Be connected in order to match with the thin-walled axle sleeve workpiece of different-diameter, the anchor clamps versatility is good.
As preferably, the diameter of anchor clamps small cylinder is 100 millimeters to 250 millimeters, and the diameter of large cylinder is 300 millimeters to 550 millimeters.It is small cylinder that anchor clamps are made into an end, this be for anchor clamps can be in lathe power chuck claw firm clamping, also be simultaneously in order to alleviate clamp weight, to save cost.
As preferably, the diameter of the screw that is strained and fixed and the aperture of through hole are complementary; The screw that is strained and fixed passes through hole and is connected with thin-walled axle sleeve workpiece, guarantees that thin-walled axle sleeve and anchor clamps are concentric.
Compared with prior art, the utility model beneficial effect is:
1, thin wall shaft is enclosed within the last clamping of lathe, finishes the turning processing of inside and outside circle simultaneously, and it is few that workpiece is reserved allowance, saves cost, and process procedure is few, has improved production efficiency.
2, thin-walled axle sleeve workpiece is connected with clamp bolt and has limited workpiece axially and motion radially, clamps firmly.
3, anchor clamps are connected with thin-walled axle sleeve workpiece end face, and anchor clamps can be fit to the workpiece of different size diameter, and the anchor clamps versatility is good.
4, thin-walled axle sleeve workpiece is connected with lathe power chuck claw by anchor clamps, and workpiece can not eliminated clamping deformation by the direct clamping of lathe power chuck claw.
