Abstract
The utility model relates to a reamer for machining, in particular to an inverted-cone-shaped reamer. The front end of the reamer is a correction and guide part, the rear end of the reamer is a reaming part, the diameter of the reaming part is larger than the diameter of the correction and guide part, a cutting blade is arranged on the correction and guide part, a reaming blade is arranged on the reaming part, and the cutting edge of the cutting blade is of an inverted cone shape. The inverted-cone-shaped reamer used in the utility model has the advantages of both a traditional reamer and a borer, can be used for realizing the rapid feeding of the reamer, is free from a rigid influence, and has diminished steering errors as the borer. The reamer provided by the utility model fuses the functions of reaming and boring, can be used for processing an iron casting with a cast hole in need of later-stage machining and a high geometric tolerance requirement, and has the advantages of high processing efficiency, strong capability of ensuring geometric tolerance, simplicity in manufacture, economy and practicability.
Description
Technical field
The utility model relates to the machining reamer.
Background technology
At present the machining of casting hole is adopted fine finishining again after the reamer roughing usually, perhaps adopt the fine finishining of bore hole form to reach the Geometrical Tolerance Principle in hole.If adopt first kind of mode, because the influence of being cast bottom outlet, reamer 2 can produce break-in in the feeding process, produce break-in error (t), and fine finishining can't be removed the break-in error, also just can't reach the designing requirement (see figure 1).The second way can greatly be improved the break-in error, but is subjected to pore size and hole length influence, and the rigidity of boring cutter 5 bars can't realize fast feed, and its working (machining) efficiency is too low again, can't satisfy production demand (see figure 2).
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of back taper reamer is provided, and solves the simple reaming and the problem of boring capacity deficiency, makes simply, and is economical and practical, the cutter of raising the efficiency.
The technical scheme that the utility model is adopted for achieving the above object is: the back taper reamer, the reamer front end is for proofreading and correct the guiding position, the rear end is the reaming position, reaming position diameter is greater than proofreading and correct guiding position diameter, proofread and correct the guiding position cutting tip is installed, the reaming blade is installed at the reaming position, and the cutting edge of cutting tip is back taper.
The inclination angles of described cutting tip back taper is between 5 °～7 °.
The utility model uses the back taper reamer to have the advantage of traditional reamer and boring cutter concurrently, can realize the fast feed of reamer, is not subjected to rigidity effects to reduce the break-in error as boring cutter again.The cutting edge of general reamer front end cutting tip is designed to back taper, when current end cutting edge is worked, at first cut workpiece, play the correction guiding function by the circle that wedge angle is formed, guiding rear portion reaming blade guarantees that to reach vertical feed next step fine finishining reaches the required precision of workpiece.The inclination angles of the utility model cutting tip is between 5 °～7 °, and the intensity of cutting edge can guarantee, and angle is not difficult on making.The utility model reamer merges reaming and bore hole function, adopts the processing of the utility model reamer to have casting hole, and this casting hole later stage needs machining and has the high ironcasting of Geometrical Tolerance Principle simultaneously, the working (machining) efficiency height, guarantee that the form and position tolerance ability is strong, make simple, economical and practical.
Description of drawings:
Fig. 1 is present reamer structural representation.
Fig. 2 is present boring cutter structural representation.
Fig. 3 is the utility model structural representation.
Fig. 4 is the utility model user mode figure.
Fig. 5 is a partial enlarged drawing among Fig. 4.
Among the figure: 1 workpiece; 2 reamers; 3 cutting tips; 4 reaming blades; 5 boring cutters.
The specific embodiment:
Back taper reamer shown in Fig. 3-5, reamer 2 front ends are for proofreading and correct the guiding position, the rear end is the reaming position, reaming position diameter is greater than proofreading and correct guiding position diameter, proofread and correct the guiding position cutting tip 3 is installed, reaming blade 4 is installed at the reaming position, and the cutting edge of cutting tip 3 is back taper, and the inclined angle alpha angle of cutting tip back taper is between 5 °～7 °.
During work, the circle that front end cutting edge (Fig. 5) is made up of wedge angle is at first cut workpiece 1, plays the correction guiding function, and the reaming blade at guiding reaming position, rear portion guarantees that to reach vertical feed next step fine finishining reaches the required precision of workpiece.
