Blisk is the core component of aero-engine of new generation, and its application is the important behave that improves engine performance, simplified structure, reduction weight, reduces fault rate, raising durability and reliability.Architectural characteristic that blisk is complicated and difficult to machine material characteristic have brought difficulty for polishing processing; External integrated impeller blade profile polishing technology is carried out tight blockade on new techniques to China; The present domestic self adaptation polishing technology that had; Mainly be to utilize grinding head for polishing mechanism, make polishing wheel carry out polishing operation in the blisk profile.
But the domestic grinding head for polishing mechanism that adopts in the course of the work; The influence that changed by polishing force, and grinding head mechanism lacks the bistrique control of position, bistrique tends to depart from its equilbrium position, center in polishing process; Cause polishing back blisk surface quality undesirable, uniformity is poor.Therefore, need the novel grinding head for polishing mechanism of research badly, be convenient to, to improve the quality of finish of blisk to the bistrique control of position.
The utility model content
The technical problem that solves
Lack the bistrique control of position for solving in the existing grinding head for polishing mechanism, cause at polishing processing, the bistrique position can be influenced by polishing force and depart from the problem of equilbrium position, center, and the utility model proposes a kind of grinding head mechanism that is used to polish blisk.
Technical scheme
The technical scheme of the utility model is:
Said a kind of grinding head mechanism that is used to polish blisk is characterized in that: comprise the circular cone cavity, cylindrical cavity, cylinder ring tight sleeve, cylinder, bearing holder (housing, cover) and main shaft; The circular cone cavity is the hollow thin-wall structure, on circular cone cavity big opening end face, along the circumferential direction is evenly equipped with screwed hole, is used for circular cone cavity and machining tool are fixed; The cylindrical cavity coaxial bolts is fixed on the osculum end of circular cone cavity, and the set bolt of cylindrical cavity and circular cone cavity along the circumferential direction is uniformly distributed with; On the cylindrical cavity sidewall, along the circumferential direction be evenly equipped with some cylinder mounting holes; Cylinder is installed in the cylinder mounting holes; The output shaft of cylinder passes the cylindrical cavity sidewall; Stretch in the cylindrical cavity center cavity, outside the cylindrical cavity sidewall, be with the cylinder ring tight sleeve, cylinder is fastened in the cylinder mounting holes; Main shaft is installed in circular cone cavity and the cylindrical cavity; And alignment of shafts axis and cylindrical cavity central axis conllinear, main shaft one end is connected with the electric main shaft of machining tool through shaft coupling, and the main shaft other end is through chuck fixing polishing cutter; Spindle jacket has bearing holder (housing, cover); Along the circumferential direction be evenly equipped with some grooves on the bearing holder (housing, cover) sidewall, cylinder output shaft and groove fit constrain in the center with bearing holder (housing, cover) and main shaft.
Said a kind of grinding head mechanism that is used to polish blisk, wherein cylinder is the double output shaft cylinder, two output shaft synchronization telescopes.
Said a kind of grinding head mechanism that is used to polish blisk, wherein all cylinders adopt same source of the gas air feed, guarantee that the power output of all cylinders is identical.
Beneficial effect
The cylinder that the utility model adopted has the dual output piston rod construction, and all cylinders adopt same source of the gas, makes that the power output of all cylinders is identical, has guaranteed that main shaft is in the equilbrium position under free state.The utlity model has simple in structurely, easy for installation, the advantage that positioning accuracy is high simultaneously can reach the purpose of regulating polishing force through the gas flow of regulating cylinder, has improved the control ability to the blisk polishing process.

The specific embodiment
Below in conjunction with specific embodiment the utility model is described:
With reference to accompanying drawing 1, the described a kind of grinding head mechanism that is used to polish blisk of present embodiment comprises circular cone cavity 1, cylindrical cavity 5, cylinder ring tight sleeve 4, cylinder 7, bearing holder (housing, cover) 3 and main shaft 2.Circular cone cavity 1 is the hollow thin-wall structure, on circular cone cavity 1 big opening end face, along the circumferential direction is evenly equipped with three circular cone cavity installing holes 8, is used for circular cone cavity 1 and machining tool are fixed; Cylindrical cavity 5 is through three construction bolts, the 9 coaxial osculum ends that are fixed on circular cone cavity 1, and three construction bolts 9 along the circumferential direction are uniformly distributed with.
On cylindrical cavity 5 sidewalls, along the circumferential direction be evenly equipped with three cylinder mounting holes, cylinder 7 is installed in the cylinder mounting holes, and cylinder adopts two synchronous output piston axles, and two the axis of the pistons all pass cylindrical cavity 5 sidewalls, stretches in the cylindrical cavity center cavity.In three cylinder mounting holes, also have 10, three cylinders of cylinder port 7 and adopt same source of the gas air feed, make the identical displacement of output piston axle synchronization telescope of three cylinders, thereby onesize power output can be provided.Outside cylindrical cavity 5 sidewalls, be with cylinder ring tight sleeve 4; On cylinder ring tight sleeve 4, be equipped with and hold out against screw 6; Holding out against screw 6 is fastened on cylinder 7 in the cylinder mounting holes; Hold out against screw 6 through dismounting and can dismantle cylinder 7 easily, also can reach the purpose of fine setting main shaft 2 positions through the tightness that adjusting holds out against screw 6.
