Abstract
The invention discloses an inner ejection pump reamer and relates to a reamer. The inner ejection pump reamer comprises a reamer bit and a reamer bar; the reamer bit is provided with a cutting edge; the reamer bit is detachably connected with the reamer bar; a scrape discharging hole is formed on the reamer bit; the reamer bar has a circular tube shape; the scrape discharging hole on the reamer bit is communicated with an tube cavity of the reamer bar; the reamer bit is provided with two burnishing edges preferably; the peripheries of the burnishing edges and the cutting edge are positioned on the same cylindrical surface, and the burnishing edges slightly lag behind the cutting edge along the axial direction; two arc scrape discharging grooves are formed on the outer wall of the reamer bit close to the burnishing edges; and an L-shaped scrape discharging groove is formed close to the burnishing edges. Preferably, the reamer bit is connected with the reamer bar though a thread. The inner ejection pump reamer has stable quality, high efficiency and generality, is low in processing cost, meets different requirements of processing a through hole and a blind hole by changing a scrape discharging mode, solves the problem of difficulty in processing longhole aluminum barrel parts, particularly difficulty in discharging scraps during processing of the blind hole better, and has the wide application value.
Description
Technical field
The present invention relates to a kind of machine and add cutter, relate in particular to a kind of interior spray and inhale reamer.
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
Problem at above-mentioned prior art existence, the invention provides a kind of interior spray and inhale reamer, this cutter steady quality, the efficient height, processing cost is low, and versatility is good, can be by changing the different demands that the chip removal mode satisfies processing through hole and blind hole, solved the problem that deep hole aluminum barrel part processing difficulty, particularly blind hole add chip removal in man-hour difficulty preferably, had extensive use and be worth.
Technical scheme of the present invention is: reamer is inhaled in spray in a kind of, comprises cutter head and knife bar, and cutter head is provided with cutting edge, and described cutter head and knife bar removably connect, and have discharging opening on the cutter head, and knife bar is the pipe shape, and the discharging opening of cutter head is communicated with the interior tube chamber of knife bar; Cutter head is provided with the burnishing-in sword, and the outer rim of burnishing-in sword and cutting edge is positioned on the same face of cylinder, and the burnishing-in sword lags behind cutting edge a little vertically; The cutter head outer wall has the circular arc chip area near the position of burnishing-in sword, and the position of close cutting edge has a L shaped chip area.
As preferably, described cutter head is threaded with knife bar.
As preferably, described burnishing-in sword is two, and described circular arc chip area is two.
The invention has the beneficial effects as follows: use the principle of reamer and two kinds of processing methods of burnishing-in, and they are combined, improve the efficient of processing greatly, and reduced processing cost.Be provided with cutting edge and burnishing-in sword on the cutter head of the present invention simultaneously, allow the burnishing-in that will begin in a minute after the fraising, the beginning extrusion process reduces the wearing and tearing of burnishing-in sword before aluminum component endoporus retraction, the quality of raising product.Can process roughness at Ra0.2, linearity φ 0.06mm, dimensional accuracy 0.04mm, the degree of depth surpasses the deep hole aluminum component of 500mm.Utilize the chip-removal hole on circular arc chip area and L shaped chip area and the cutter head and the interior tube chamber of 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 head and knife bar are 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, and be very practical.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is that P of the present invention shown in Figure 1 is to view;
Fig. 3 is a working state schematic representation of the present invention.
The specific embodiment
As one embodiment of the present invention, as depicted in figs. 1 and 2, reamer is inhaled in a kind of interior spray, comprise cutter head 1 and knife bar 2, cutter head 1 is provided with cutting edge 4, and described cutter head 1 removably connects with knife bar 2, in the present embodiment, as preferably, described cutter head 1 is threaded with knife bar 2.Have discharging opening 5 on the cutter head 1, knife bar 2 is the pipe shape, and the discharging opening 5 of cutter head 1 is communicated with the interior tube chamber 6 of knife bar 2; Cutter head 1 is provided with burnishing-in sword 3, and the outer rim of burnishing-in sword 3 and cutting edge 4 is positioned on the same face of cylinder, and burnishing-in sword 3 lags behind cutting edge 4 a little vertically; Cutter head 1 outer wall has the circular arc chip area near the position of burnishing-in sword 3, and the position of close cutting edge 4 has a L shaped chip area.In the present embodiment, as preferably, described burnishing-in sword 3 is two, and described circular arc chip area is two.
The course of work of the present invention is as follows: knife bar 2 is fixed on the lathe bed by rolling bearing, drives knife bar 2 move left and right by tailstock and carries out deep hole machining.The burnishing-in sword 3 that is provided with on the cutter head 1 makes that having cut with scissors endoporus can begin to carry out burnishing-in, guarantees roughness at once.The serial reamer that can make the different size size according to the external diameter and the knife bar 2 of three sword compositions on the cutter head 1 makes up.As long as guarantee the rigidity and the linearity of knife bar 2, just can guarantee the linearity of processing parts 7.As shown in Figure 3, during work, can select cutter head 1 according to hole size in the part to be processed 7, be connected with knife bar 2, knife bar 2 is connected with tailstock.Processing parts 7 is fixed on the main shaft, and by the main shaft driven rotary, knife bar 2 drives cutter heads 1 and enters processing parts 7 and carry out the processing of boring hinge then.During the processing through hole, cooling-lubricant can pass through the circular arc chip area of cutter head 1 outer surface and the discharging opening 5 of L shaped chip area and slit and cutter head 1 and the interior tube chamber 6 of knife bar 2 and feed simultaneously, discharges from processing parts 7 undressed ends; During processing blind hole, circular arc chip area and L shaped chip area and the slit of cooling-lubricant by cutter head 1 outer surface enters, and discharged by the discharging opening 5 of cutter head 1 and the interior tube chamber 6 of knife bar 2.Circulation by cooling-lubricant is to processing parts 7 and cutter head 1 cooling and lubricating, and the aluminium of generation bits are also discharged by the negative pressure of liquid flow, avoids stifled bits and scratches workpiece.Can realize the automation of processing greatly having improved production efficiency by programme-control.
