Technical field
The utility model relates to a kind of deep hole machining field, particularly a kind of reamer for deep hole machining.
Background technology
In machined, often run into deep hole machining, and be exactly reamer for one of the common tool of deep hole machining.Reamer is by the restriction in aperture, and the diameter of drilling rod is little, and length is large, and the therefore poor rigidity of drilling rod, intensity is low.Easily produce vibration man-hour adding, ripple, tapering and affect linearity and the surface roughness of deep hole.Because machining hole has certain depth, determine that the reamer tool that whether puts in place acquires a certain degree of difficulty.Need to apply axial power to reamer in process, but often because undue force causes knife edge part to damage, reduce service life.
Utility model content
The purpose of this utility model is to provide the reamer for deep hole machining that a kind of deep hole machining linearity well also can effectively prevent from causing blade to damage because of overexertion.
The technical scheme realizing the utility model object is: the utility model has body; Described body comprises drill bit, drilling rod and Morse taper shank; Described drill bit comprises blade part and the connecting rod being connected blade part; The end face that described drilling rod is connected with drill bit is provided with transmission chute; The connecting rod of described drill bit is slidably arranged in transmission chute, is provided with back-moving spring between the free end of connecting rod and the bottom of transmission chute; The cross section of described connecting rod and transmission chute is polygon, and transmission chute coordinates with connecting rod.
Be set with guide post outside above-mentioned drilling rod, drilling rod rotates and is arranged in guide post, and drill bit stretches out from one end of guide post, and Morse taper shank stretches out from other one end of guide post; The diameter of described guide post is less than the diameter of drill bit; The outer wall of described guide post is provided with two or more along the equally distributed chute of its circumference, and chute is stretched along the radial direction edge of guide post axis; A guidance set is equipped with in described each chute; Described guidance set comprises guide pad and spring, and guide pad is slidably arranged in chute, is provided with spring between guide pad and the bottom of chute; The free end of described guide pad stretches out chute and the end face of free end exceeds the external diameter of drill bit.
Above-mentioned guide pad is ball; The mouth diameters of described chute is less than the diameter of guide pad, and guide pad to be slidably arranged in chute and to be provided with spring between guide pad and the bottom of chute; The part that described ball stretches out chute is free end.
The inwall of above-mentioned guide post is provided with bearing, and the external stator of bearing is fixedly connected with the inwall of guide post, and the internal rotor of bearing is fixedly connected with drilling rod.
Above-mentioned guide post is provided with external screw thread, external screw thread coordinates and is provided with stop nut; The external diameter of described stop nut is greater than the diameter of drill bit.
The utility model has positive effect: (1) the utility model makes to there is certain buffering between drill bit and drilling rod by back-moving spring, can have certain buffering when overexertion, improves the service life of reamer; (2) the utility model is by guide post, adds the rigidity of reamer, improves the speed of deep hole machining; (3) the utility model achieves the linearity of reamer by guidance set, improves crudy; (4) the utility model can improve result of use and the service life of whole reamer by bearing; (5) the utility model can realize pre-determined bit by stop nut, to determine working depth, improves crudy and process velocity.
