Abstract
The utility model discloses an internal ejection reamer which comprises a reamer body, wherein a plurality of blades are arranged at one end of the reamer body; the other end of the reamer body is detachably connected with a reamer bar; the outer diameter of the reamer bar is smaller than the outer diameter of the blade end of the reamer body; the reamer bar is locked with the reamer body; a chip outlet penetrating through the reamer bar and the reamer body is formed inside the reamer bar and the reamer body along the axis; and the blade of the reamer body consists of a chip cutting blade and a burnishing blade. The internal ejection reamer adopts a formed boring reamer, the reamer bar is connected with a power device, and the internal ejection reamer adopts the mode that the workpiece rotates and the reamer is fixed, so that the aluminum chips can be discharged from the inner part of a main shaft and from an inner hole of the reamer, and deep hole and blind hole parts with the roughness of Ra 0.2, straightness of Phi 0.06mm, dimensional accuracy of 0.04mm and depth more than 500mm can be machined; in addition, the reamer has stable quality in practical use, high efficiency, low machining cost and good generality, better solves the problem of difficult machining of the aluminum tube parts of the company, particularly the deep hole and blind hole aluminum tube parts, and has a wide application value.
Description
Technical field
The utility model relates to a kind of cutter of processing the endoporus of aluminum component, and reamer is inhaled in the interior spray that relates in particular to the higher endoporus of a kind of roughness of processing aluminum component and tolerance.
Background technology
At present, the endoporus of aluminium class part adds man-hour, and general main employing clamped cutting bit sheet carries out bore hole or fraising etc., also has to adopt interior spray suction reamer to process.But the part for roughness requires more than Ra0.8 also need increase by one extrusion process.For more shallow endoporus, such processing method can guarantee requirement.But adopt the extrusion process cost higher to the part of having relatively high expectations, and to darker endoporus processing difficulties, linearity is difficult to guarantee.Especially during the dark blind hole of processing, boring strand chip removal difficulty and extruding are difficult to realize.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of interior spray to inhale reamer, can process roughness at Ra0.2, linearity φ 0.06mm, and dimensional accuracy 0.04mm, the degree of depth surpasses the deep hole aluminum component of 500mm.This cutter is stable through actual service property (quality), the efficient height, and processing cost is low, and versatility is good.Solved my company aluminum barrel part, especially deep hole, blind hole aluminum barrel part processing difficult problem preferably, had extensive use and be worth.
The technical solution of the utility model is: reamer is inhaled in spray in a kind of, comprise cutter hub, one end of cutter hub is provided with several blades, the other end of the described cutter hub knife bar that removably connects, the external diameter of described knife bar is less than the external diameter of cutter hub blade end, the locking of knife bar and cutter hub, and the inside of knife bar and cutter hub has the discharging opening that runs through the two along axis, and the blade of described cutter hub is made up of cutting edge and burnishing-in sword.
As preferably, described cutter hub outer wall has the circular arc chip area near the position of burnishing-in sword, has a L shaped chip area near the position of cutting edge.
As preferably, described being detachably connected as is threaded.
As preferably, the quantity of the unnecessary cutting edge of quantity of described burnishing-in sword.
As preferably, described cutting edge is one, and described burnishing-in sword is two.
The beneficial effects of the utility model are: the principle of mainly using reamer and two kinds of processing methods of burnishing-in, and they are combined, improve the efficient of processing greatly, burnishing-in will begin in a minute after the fraising, beginning extrusion process before aluminum component endoporus retraction, reduce the wearing and tearing of burnishing-in sword, improve the quality of product.Adopted shaping boring reamer, be connected with power set by knife bar, adopted the fixing mode of workpiece rotary cutter, the aluminium bits are discharged by the discharging opening of main shaft inside or knife bar inside.Utilize the discharging opening of circular arc chip area and L shaped chip area and cutter hub and knife bar, can be by changing the different demands that the chip removal mode satisfies processing through hole and blind hole, solved the processing of deep hole machining and blind hole simultaneously, problems such as the difficult processing of particularly very dark blind hole processing, chip removal difficulty.Cutter hub and knife bar can be made into the multiple series specification technical combinations that can adjust replacing, satisfy the aluminum component endoporus processing request of the various degree of depth and internal diameter, guarantee high accuracy, roughness and Geometrical Tolerance Principle.
