Description
Technical field
The present invention relates to the air bag polishing machining tool, especially relate to the online trimming device of a kind of air bag polishing tool and online method for trimming thereof.
Background technology
The air bag polishing technology is a kind of new finishing method proposed the nineties in 20th century, especially is applicable to the polishing of curved surface.The air bag polishing technology is adopt the spherical envelope with certain inflation pressure or paste polishing pad at gasbag outer surface, as polishing tool, processed curved surface is carried out to polishing.With traditional finishing method, compare, air bag polishing has following characteristics: the surperficial anastomose property of rubbing head and polished workpiece is good, can realize by controlling the blowing pressure the control of working (machining) efficiency and surface quality simultaneously.There is the advantages such as controllability and certainty because of the air bag polishing technology, so it is a kind of curved surface polishing method with development potentiality.
At present, there are many companies and research institute to be devoted to the research of air bag polishing theory and technology both at home and abroad, and obtained certain achievement.But the maximum gauge of the optical mirror plane of the IRP series burnishing machine polishing that is applied to axial symmetry replicated optics device of Zeeko company exploitation is 2.3m, the clearance of BK7 glass is reached to 120mm
3/ min, glass surface after the wheel grinding of granularity 800 is carried out to the polishing test, obtained surface roughness (the D D Walker et al.Commissioning of the first Precessions1.2m CNC Polishing Machines for Large Optics.Proc.of SPIE Vol.6288 of Ra2.47nm, 62880P, 2006); The people such as the Gao Bo of Harbin Institute of Technology (Gao Bo, thank to outline, Yao Yingxue, Yuan Zhejun. New technology of ballonet tool for polishing. optical technology, Vol.30 (3), 2004.) adopt air bag polishing tool for the BK7 glass material, carry out processing experiment on CNC milling machine, obtained the smooth surface of Ra0.5nm.
Along with the surface to be machined material of workpiece is removed, wearing and tearing have also occurred in air bag or polishing pad.In polishing process, the wearing and tearing of air bag or polishing pad not only can affect the efficiency of processing, and can affect the situation that contacts of polishing tool and surface to be machined, thereby have affected the certainty of polishing precision and polishing process.Therefore, in polishing, need air bag or polishing pad are repaired.At present, also considerably less for the trimming device of air bag polishing tool both at home and abroad; And existing trimming device is system independently mostly, there are the problems such as cost is high, specificity strong, complicated operation.Therefore, designing online method for trimming and the device thereof that a kind of cost is low, applicability is wide, simple to operate is significant to polishing processing.
Summary of the invention
The object of the invention is to the problem for air bag polishing tool wearing and tearing, a kind of simple in structure, operation is convenient, cost the is low online trimming device of air bag polishing tool and online method for trimming thereof are provided.
The online trimming device of a kind of air bag polishing tool of the present invention, comprise support, knife rest, dressing tool, spring and steel ball;
Knife rest is rack-mount and be rotationally connected with support, dressing tool is arranged on knife rest, knife rest is provided with caulking groove, spring and steel ball are located in caulking groove, spring is positioned at the caulking groove bottom, spring contacts steel ball, at the composition surface of support and knife rest, is provided with the Switch of working position detent, and described steel ball card terminates in the Switch of working position detent.
Described knife rest can be by knife rest clamping screw and support locking, and described dressing tool can be locked on knife rest by the cutter clamping screw.
Described Switch of working position detent can comprise finishing state detent and idle condition detent.
Described knife rest clamping screw preferably overlaps the external stability ring, and the external stability ring can prevent knife rest locking bolt falling, also is convenient to the knife rest rotation simultaneously.
The online method for trimming of air bag polishing tool of the present invention, adopt the online trimming device of air bag polishing tool of the present invention, comprises the following steps:
1) rotating turret, to vertical direction, makes dressing tool upward, and locking cutter clamping screw is fixed knife rest;
2) open the burnishing machine main shaft, adjust the air bag polishing tool of burnishing machine, make the summit of air bag of air bag polishing tool in minimum point, and the XYZ axle of controlling burnishing machine moves, until the summit of air bag contact dressing tool;
3) control air bag polishing tool and move down, air bag polishing tool is swung back and forth, realize the finishing of dressing tool to balloon surface;
4) after finishing finishes, the knife rest clamping screw of outwarding winding, pull knife rest, makes knife rest go to clear position, and now dressing tool is parallel to the workbench surface, locking knife rest clamping screw.
Compared with the prior art, beneficial effect of the present invention is as follows:
When the present invention uses, the described support at trimming device is arranged on the workbench of air bag polishing lathe.The cutter clamping screw, for being locked dressing tool station of living in position, prevents that dressing tool is moved.While dropping in the Switch of working position detent, realized the location that knife rest rotates around rotating shaft under the effect of steel ball at spring; Knife rest is under certain active force, and steel ball can skid off smoothly from the Switch of working position detent, and knife rest can rotate around support.When knife rest rotates to station position and clear position (being that steel ball is positioned at finishing state detent and idle condition detent), then screw the knife rest clamping screw, just knife rest can be fixed on support.When the trimming polished instrument of needs, knife rest is set to operating position; When not needing finishing, knife rest is set to clear position.
Owing to adopting technique scheme, the online trimming device of air bag polishing tool of the present invention has simple in structure, and operation is convenient, and cost is low, can realize the online finishing of air bag polishing tool.
The present invention not only can repair the spherical envelope polishing tool of any radius, and can repair other any convex curved surface (as parabola, aspheric surface) polishing tools.While repairing not coplanar shape polishing tool, do not need any part of modifier simultaneously, only need to revise the program in machine tool numerical control system, avoided the continuous mounting or dismounting of air bag polishing tool, eliminated the repetition alignment error of air bag polishing tool.It is simple in structure, and the complicated control system without the need for other only need to utilize the system of burnishing machine itself just can realize grooming function, so can greatly reduce the cost that air bag polishing tool is repaired.
