Technical field
The utility model relates to a kind of attachment cap clamping, belongs to Machining Technology field.
Background technology
Thin-walled parts in machining product is a kind of more difficult processing parts.Wherein, rotary work piece is the most typical in thin-walled parts.Because the rigidity of rotary thin-wall workpiece self is inadequate, flexibility is had a surplus, and general clamping can not meet machining accuracy, also has clamping force that thin-walled parts can be caused to be out of shape and causes form error, make rotary thin-wall work pieces process qualification rate low.
Axle core retainer plate is adopted to enter in rotary thin-wall workpiece diameter to improve the rigidity of processing, suitable installation way can reduce the distortion making thin-wall workpiece because of the comprehensive error of lathe self and the processing of fixture itself and alignment error, and appropriate cutting force can alleviate the distortion of lathe system and cutter, effectively improve the process reliability of rotary thin-wall part.
In addition, one end of rotary thin-wall part embeds attachment cap internal locking location.Thin-walled parts is subject to the clamping force effect of claw in radial direction, easily produces following error: thin-walled parts produces elastic deformation when clamping; During clamping, part offsets, and changes the position determining should have when locating; Juxtaposition metamorphose between part locating surface and fixture support face.Therefore, thin-walled parts is risky factor in installation, clamping, and location thin-walled parts, reduces clamp error, make thin-walled parts uniform force; To the Set and Positioning of processed thin-walled parts, the determination of stress point; And in working angles, be in one between processed thin-walled parts and cutter to keep being all the key element will considered in processing thin-walled part process and frock in the dynamic balance state of rigidity.
Utility model content:
Processed rotary thin-wall part, for clamp error in the processing of rotary thin-wall part, embeds in attachment cap and mates locking positioning, thus increase workpiece stiffness, be convenient to determine stress point Precision Machining by the utility model.Feed circuit adopts the continuous tool path pattern of first car rotary work piece external diameter, and same surface is completed in continuous cutting process; Then substep feed car internal diameter, avoids inside groove to be out of shape and produces cone angle.
The utility model proposes a kind of attachment cap clamping, comprise scroll chuck, axle core, attachment cap, screw, workpiece, described attachment cap is fixed on the center of described scroll chuck by described screw, described workpiece is enclosed within described axle core, and described workpiece embeds coupling locking positioning in described attachment cap.
Preferably, described attachment cap is stainless steel.
Preferably, described workpiece is rotary work piece.
Preferably, described workpiece is enclosed within described axle core, then is embedded in described attachment cap by described workpiece and mate locking positioning; Adopt continuous tool path pattern, cyclic program setting cutting output cuts the described same surface of workpiece external diameter;
Taking out described workpiece is oppositely enclosed within described axle core, and being partially submerged in described attachment cap of having cut is mated locking positioning; Take the symmetrical tool path pattern of substep, profile program setting cutting output is cut described workpiece and is not completed part: first time feed circuit extends to described attachment cap by described excircle of workpiece groove, makes cutting force point to the center of circle; Second time feed circuit is outside by described inner hole of workpiece, makes cutting force point to described inside workpiece; Described workpiece is rotary work piece; Described attachment cap is stainless steel.
Preferably, described attachment cap is silicon-aluminum alloy material.
The utility model adopts the preparation process of attachment cap clamping as follows, and rotary work piece is enclosed within axle core, then mates locking positioning by described rotary work piece embedding attachment cap;
Adopt continuous tool path pattern, cyclic program setting cutting output cuts the same surface of rotary work piece external diameter;
Taking out rotary work piece is oppositely enclosed within axle core, and being partially submerged in attachment cap of having cut is mated locking positioning;
Take the symmetrical tool path pattern of substep, profile program setting cutting output is cut rotary work piece and is not completed part:
First feed circuit extends to attachment cap by rotary work piece peripheral groove, makes cutting force point to the center of circle;
Second feed circuit is outside by rotary work piece endoporus, makes cutting force point to rotary work piece inner.
When numerical programming procedure, adopt cyclic program and wheel profile program two kinds of modes to combine, directly set cutting depth in cyclic program, reasonably chipping allowance is set, can not arbitrarily change; Avoid the risk brought due to misoperation; Reduce the potential quality risk that manual repeatedly upper slitter benefit counting loss is brought, also eliminate computing time; Ensure that the stability of product processing quality; Realize the unmanned intervention of single work step numerical control lathe process.
Numerical control program cutting line designs: adopt symmetrical new-type processing method of cutting, first Vehicle Processing cylindrical is symmetrical Vehicle Processing endoporus again; The stress partial offset produced in process is fallen, effectively controls the distortion that part process produces, better meet the requirement of design drawing.
In sum, the allowance of each operation of reasonable distribution and work step, effectively controls part deformation.Adopt relative, opposing tool path pattern, the stress partial offset produced in process is fallen, reduce the distortion that process produces.Adopt cyclic program and wheel profile program two kinds of modes to combine, utilize cyclic program to avoid the mistake produced; After cyclic program process finishing, adopt wheel profile program, ensure roughness and the machining accuracy of piece surface.Cutting data in numerical control program is fixing, can not arbitrarily change, and directly can control product quality.
The utility model discloses a kind of attachment cap clamping and technique, introduce attachment cap and coupling locking positioning is carried out to rotary thin-wall part, to improve the rigidity of processing, reduce pinching deformation error, make rotary thin-wall part stress even; The effective Set and Positioning to processed thin-walled parts, determines stress point; And cutting line mode is rationally set in working angles, allow between processed thin-walled parts and cutter and be in the dynamic balance state that keeps rigidity.
