Abstract
A boring tool for an end surface with double inner holes is used for settling a problem of high accumulated error caused by multiple times of tool change for machining in machining process of end surface machine for bracket holes of a coating roller bracket. The technical solution of the boring tool for the end surface with double inner holes is characterized in that: the boring tool comprises a main tool rod, a left tool rod, a right tool rod, a left blade and a right blade; the left tool rod and the right tool rod are respectively fixed at the front end of the main tool rod; the left blade and the right blade are symmetrically equipped on the left tool rod and the right tool rod. When the boring tool provided by the utility model is in use, the main tool rod is pressed on a numerical control lathe tool platform, and the boring tool is programmed through the dimensions of the left blade and the right blade. Through respective cutting of the left blade and the right blade, machining on the bracket holes and four large end surfaces without tool change after one-time clamping of the coating roller bracket is realized. Furthermore the machining pattern of the end surface is concentric with the holes. Furthermore when the accumulated error of clamping and form and position error between the hole and the end surface are reduced, the operation efficiency is improved.
Description
Technical field
The utility model relates to a kind of machining tool, especially for hole end surface boring cutter in the duplex of processing coating roll support.
Background technology
The coating roll support is vital part in the brushing equipment, its structure as shown in Figure 6, the lower end of coating roll support 7 is the circular arc base, is provided with two supports above base side by side, the assembling of the bracket holes that is provided with on each support and coating roll.The manufacturing process of coating roll support is casting, machining.Two bracket holes on the support and 4 end faces of two bracket holes all require machine cut processing, and the processing dimension of end face is greater than the aperture more than one times, between two holes of support, all require than higher size and form and position tolerance between hole and the end face.According to conventional processing technology, need to adopt relatively large face and side cutter behind multiple clamping milling end face on the milling machine, bore hole processing on boring machine or lathe again.Because the restriction of the cutting feeding mode of multiple clamping and Milling Process, processing lines end face and hole decentraction, particularly machining are out of shape, repeatedly milling clamping cumulative errors make that the morpheme error control of hole and end face is difficult.
The utility model content
The utility model is used to overcome the defective of prior art and provides a kind of and can reduce the cutter clamping times, reduces the clamping cumulative errors, improves hole end surface boring cutter in the duplex of machining accuracy.
The alleged problem of the utility model is that following technical scheme solves:
Hole end surface boring cutter in a kind of duplex, special feature is: it comprises operator bar, left knife bar, right knife bar and left and right blade, and described left knife bar, right knife bar all are fixed on operator bar front end, and described left blade, right blade are symmetricly set on left knife bar, right knife bar place.
Hole end surface boring cutter in the above-mentioned duplex, described left and right blade is rhombus, and left and right blade is fixed respectively on left knife bar, the right knife bar through the push type broach screw, and the point of a knife line of described left and right blade is parallel with the operator bar.
Hole end surface boring cutter in the above-mentioned duplex, described operator bar is made up of operator bar leading portion, operator bar changeover portion, operator bar back segment successively, described operator bar leading portion is the olive shape cross section, and operator bar back segment is the square-section, and the point of a knife of described left and right blade is positioned at the horizontal central plane of operator bar leading portion.
The utility model causes the high problem of cumulative errors at the bracket holes of coating roll support, end face machining process because of tool changing processing repeatedly, has designed hole end surface boring cutter in a kind of left and right 90 ° of duplexs.Described boring cutter by the operator bar, be welded on left and right knife bar and the symmetry left and right sides blade that be fixed on left and right sides knife bar on of operator on the bar and form.During use, the bar of will operating is pressed on the CNC turning tool platform, programme with the size tool setting of left and right blade respectively, cut respectively by left and right blade, realize that clamping of coating roll support need not the processing that tool changing can be finished bracket holes and four large end faces, and make end face processing lines concentric with the hole, when reducing the clamping cumulative errors, guaranteeing the morpheme error of hole and end face, improved operating efficiency.

Label is expressed as follows in the accompanying drawing: 1. the bar of operating; 1-1. operator bar leading portion; 1-2. operator bar changeover portion; 1-3. operator bar back segment; 2. left knife bar; 3. right knife bar; 4. left blade; 5. right blade; 6. push type broach screw; 7. coating roll support.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises operator bar 1, is provided with left knife bar 2, right knife bar 3 at operator bar front end, and left knife bar, right knife bar weld fixing with the operator bar.On left knife bar, fix left blade 4 by the push type broach screw; By the fixing right blade 5 of push type broach screw, left blade, right blade are rhombus on right knife bar, and they are symmetrical arranged.
Referring to Fig. 1, Fig. 3, Fig. 4, Fig. 5, described operator bar 1 is made up of operator bar leading portion 1-1, operator bar changeover portion 1-2, operator bar back segment 1-3 successively.Operator bar leading portion 1-1 is the olive shape cross section, and operator bar back segment 1-3 is the square-section.The point of a knife line of described left and right blade is parallel with the operator bar; The point of a knife of left and right blade is positioned at the horizontal central plane of operator bar leading portion; The maximum appearance and size of left side blade, right blade and the bar leading portion of operating is less than the size of coating roll bracket holes.
When the utility model uses, the bar of will operating adds and is stuck on the CNC turning tool platform, point of a knife and the bracket holes of adjusting left and right sides blade are contour, programme with the size tool setting of left and right blade respectively, can finish the processing of bracket holes and positive and negative four large end faces of coating roll support without tool changing, and make end face processing lines and hole concentric, reduce the morpheme error that the clamping cumulative errors have guaranteed hole and end face.
