Further, the inner diameter of the lofting groove is slightly larger than the outer diameter of the shaft sleeve machining part by 0.002mm.
Furthermore, the aperture of the central through hole is 4mm, and the depth is 28mm.
Furthermore, the cutter head section of the reamer adopts a four-edge structure, and the rotating diameter is 3.175mm.
The utility model discloses a theory of operation is: the oil-free self-lubricating plastic shaft sleeve machining piece to be subjected to secondary machining is arranged in the lofting groove, the depth of the lofting groove is equal to the height of the shaft sleeve, the inner diameter of the lofting groove is slightly larger than the outer diameter of the shaft sleeve machining piece by 0.002mm, the shaft sleeve machining piece is guaranteed to be relatively fixed in the lofting groove, and the shaft sleeve machining piece can be smoothly taken out after machining is finished. After the sample is loaded, four threads are screwed after the tool base is covered, the reamer is inserted into the upper end of the tool body, the clamping section of the reamer is connected with the electric drill, the electric drill is started to rotate the reamer clockwise, and secondary machining of a shaft sleeve machined part is completed.
Compared with the prior art, the utility model, its effect is positive and obvious. The utility model discloses a with axle sleeve machined part matched with lofting groove structure to and with central through-hole matched with reamer structure, effectively solved super minification equipment accessory and add man-hour at the secondary, the verticality of reamer during operation can't be guaranteed to current processing equipment leads to the through-hole processing yields lower, and by extrusion deformation scheduling problem when the metal structure of plastics axle sleeve and processingequipment cooperates, this through-hole processingequipment simple structure, good reliability.
