Description
Technical field
The present invention relates to be applicable to a kind of anchor clamps of machining, relate in particular to a kind of anchor clamps for the processing continuous curve surface.
Background technology
Grinding machine means the lathe with grinding tool or the various surfaces of abrasive material processing work, and general being used for done precision cutting processing to the part hardened face.Grinding machine is of a great variety, and surface grinding machine is one of modal grinding machine, is mainly used in the grinding workpiece planarization.
The surface grinding machine structure is comparatively complicated, the machining accuracy height, be by emery wheel spin finishing workpiece so that it can meet the requirements of the conventional machinery process equipment of flatness, its work characteristics is: in process, produce magnetic force by the solenoid energising and be fixed on the grinder bed workpiece motionless, allow cutter rotate, with the bit alignment surface of the work, do reciprocal horizontal movement of cycle by lathe bed, cutter is feeding vertically, mode of operation both can make manually, and was also motor-driven; Main motion during the rotatablely moving of cutter in the grinding machine processing, moving horizontally of the vertical movement of cutter and lathe bed is secondary motion.
The structures shape of surface grinding machine can only satisfy the needs of precision processing plane, utilize its these characteristics, can place setting angle by adjusting workpiece, satisfy the needs of surface accuracy processing, but it can not satisfy the needs of continuity surface accuracy processing.
For example as the main tool and mould of three-roller type cold pilger mill, chute P as shown in Figure 1 is the cuboid of a coherent logical groove and continuous curve surface, and its top is a continuous curve surface of being made up of the plane of some different lengths.In roll seamless steel tube, roll is installed in the chute groove, the roll both side ends is moved at chute continuous curve surface seat of honour oscillation cycle, finish the metal cold deformation processing to seamless steel pipe, therefore the requirement on machining accuracy of the continuous curve surface of chute is very high, especially requiring between each curved surface must be smooth connection, in case unsmooth defective occurs, will cause the motion of roll on chute to occur beating, problems such as shake, the rolling deviation and the defective that directly cause seamless steel pipe, therefore the precision of chute continuous curve surface processing, closely related with the rolling quality of seamless steel pipe.At present, the processing of the continuous curve surface of three-roller type cold pilger mill chute is finished by surface grinding machine.Because surface grinding machine can not satisfy the needs of continuous curve surface, can only process by model line mode at present, that is: in advance according to the chute specification, make the special-purpose metal model, utilize model after tinting in the chute side, to rule and make marks, then chute is placed on the flat-nose pliers on surface grinder bed fixing, according to marking, manually process several continuous curve surfaces by these some rectilinear(-al)s one by one separately, curved surface of every processing needs repeatedly to measure, readjust the angle of chute and process next curved surface with regard to unclamping flat-nose pliers after finishing, until completion.
The processing mode of above-mentioned " model line mode ": complex operation, efficient are low, and machining accuracy is not high, and need through manually polishing, revise, and could realize the smooth connection of continuous curve surface.
Except the processing mode of above-mentioned " model line mode ", constantly perfect along with Numeric Control Technology, also can adopt the mode of digital control processing, automatically adjust the angle of cutter and workpiece by computer, realize the precision processing of continuous curve surface, but a cover digitlization process equipment price is too high, has increased production cost greatly.
