Handle pursues aborning of tool of face of the circular arc inside 2 cars, regular meeting is encountered by inside face of spherical, ball and socket or inside the work that circular arc face makes, if pursue,1 is shown. Machine the tool of face of big circular arc commonly, the turn that uses orgnaization of worm wheel, worm to realize cutting tool more moves. Lesser to circular arc radius sheet batches of small spare partses, knife of commonly used example or the way that drive a knife by hand undertake machining. But be in to circular arc radius the dambered surface between R35 ～ R60mm, if use worm gear deputy the restriction that accepts a structure, also have certain difficulty with example knife and treatment of the law that drive a knife, and labor strength is great, treatment quality assures not easily. For this, the design made bulk small, tool of face of the circular arc inside the car that the structure shows 2 times like the graph. One, working principle should turn handle 9 when, transmission screw 6 in rotational nut the action of 8 falls, produce the shift of direction of edge screw axes, drive rotational column to spend 5 shift. Because turn column sells the center of 5 to sell the space of 4 centers to fiducial axis, place in circumgyrate knife 2 going up is a calm value, so rotational column is sold 5 drive circumgyrate knife to place namely 2 sell the axes of 4 to be axes roll with fiducial axis. In the meantime, rotational column is sold and rotational nut is provided as transmission screw axes and labour body of 3 axes included angle change and rotation, such rotatory knife places 2 can successive roll. Pack the lathe tool on circumgyrate knife clip the point of a knife of 1, what place along with the knife is rotational, the space that sells a center to fiducial axis with point of a knife is radius, make the circular motion of face of cutting circular arc. 2, installation is in with use method on tool carrier when installation tool, above all the space that preliminary adjustments good point of a knife sells a center to fiducial axis, make its are equal to by the radius R of face of the circular arc inside treatment. After deciding when radius of circumgyrate of point of a knife, according to the method that installs lathe tool usually, place outfit of tool of face of the circular arc inside the car on tool carrier, inside the horizontal that adjusts height of point of a knife to be passed to centre of turning circle of lathe main shaft next. Sell fiducial axis the center to be adjusted again with by coincide of position of the centre of a circle of face of the circular arc inside treatment, pull vertical, horizontal stroke next board positional lock is decided, be opposite handle scale null. When turning, according to how many of mental allowance, exit lathe tool by null, it is OK that position of point of a knife is adjusted pair of knives undertake on the direction that controls cutting deepness, remember scale is worth, turn point of a knife to the position of rest of face of cutting circular arc again, can have half fine vehicle and car of essence of life, till procrastinate board scale enters null. More to mental allowance work, should use before tool of round inside use car dambered surface drive Dao Faxian internally circular arc face has thick car, have half fine vehicle and car of essence of life by afore-mentioned methods again next. 3, characteristic this tool structure is simple, radius of lathe tool circumgyrate has certain adjustment to measure, the treatment of face of the circular arc inside radius can differ inside contented and certain limits. Because the circumgyrate radius of lathe tool point of a knife is usable,measure control, and transmission screw can achieve even feed, can satisfy those who have certain precision demand so inside the treatment of circular arc face. Tool installation is convenient, the operation is simple. Because the circumgyrate horn of clip of point of a knife is less than 100 ° , the installation position of the tool should note when using, make its accord with the requirement that face of the circular arc inside workpiece machines.
