As further improvement of the utility model scheme, described bearing pin I at least 2, described pin shaft II at least 1.
Operation principle of the present utility model:
When carrying out ream or attrition process to workpiece, initiatively connecting axle is connected with machine tool chief axis, passive connecting axle is connected with reamer handle of a knife or milling tool, in active connecting axle large end outer one, end face is placed with little steel ball, large steel ball is placed with in the bulge loop face of the large end of active connecting axle, passive connecting axle with the center of large steel ball for fulcrum does spherical track motion, thus can be convenient to reamer or milling tool enters in processed piece bores.
When workpiece is cut with scissors or attrition process time, machine tool chief axis drives initiatively connecting axle to rotate, moment passes to passive connecting axle by big steel ball and cushion block, make to be loaded on reamer in passive connecting axle or synchronous rotary made by milling tool, now, the spring II contacted with big steel ball can play the effect cushioning and locate; Simultaneously, initiatively the axial force of connecting axle passes to passive connecting axle and the reamer be loaded in passive connecting axle or milling tool by 2 bearing pins, I, 1 pin shaft II and little steel ball, reamer or the milling tool axial feed degree of depth can be controlled, now, the spring I contacted with small ball can play the effect cushioning and locate.Morse's taper and the machine tool chief axis endoporus of active connecting axle cylindrical match, and the Morse's taper in passive connecting axle is matched with reamer handle of a knife or is connected with milling tool by screw thread.
Accurate floating clamping device described in the utility model,
The effect transmitting axial force is played on the one hand by the initiative drive shaft in device, passive power transmission shaft, bearing pin I, pin shaft II and little steel ball; Play by the initiative drive shaft in device, passive power transmission shaft, large steel ball, spring I, spring II effect transmitting revolving force on the other hand, its medium and small steel ball, large steel ball, spring I and spring II play the effect of location and buffering.
Therefore, this device has driven clamped reamer or milling tool within the scope of 360 degree, do spherical track motion in machining process, effectively eliminate because machine tool chief axis rotates the skew at the circular runout that produces and reamer, milling tool center and processed piece bores center, reamer or milling tool are consistent in whole ream, process of lapping, stable ream and attrition process all the time with center, processed hole.The utility model is applied on machine tool, and its overall structure is simple, ensure that the fraising of workpiece and the precision of grinding hole, improves production efficiency, reduce production cost.
