Abstract
The utility model belongs to an improved design to the existing automatic cutter-drawing machinery. The automatic cutter-drawing machinery in the prior design of the machine tool are all arranged on the main shaft of the mill heads, so the mill head is very complex. The utility model makes the automatic cutter-drawing machinery designed on the milling cutter head, so the roughing and the finishing can be completed at one time. The automatic cutter-drawing after cutting omits the cutter-drawing machinery on the main shaft and simplifies the structure of the mill head. The automatic cutter-drawing machinery is an ideal processing tool in the field of the mechanical process and is particularly applicable to the plane milling of the combined machine tool.
Description
The utility model is a kind of novel planar milling automatic cutter relieving mechanism that is used for field of machining.This slabbing automatic cutter relieving mechanism is the improvement invention about the automatic cutter relieving mechanism in the milling machine structure.
The effect of this technical field slabbing automatic cutter relieving mechanism of the prior art is after lathe is finished slabbing processing, often to require workpiece reposition or milling head reposition.Workpiece and cutter just produce relative motion like this, scratch machined surface in order to prevent cutter, and the heavy wear that prevents the Tool in Cutting sword, require cutter to retreat and leave finished surface, realize that in process the mechanism of this motion is called automatic cutter relieving mechanism.According to the type of drive of cutter relieving motion three kinds of pneumatic, machinery and hydraulic pressure are arranged.Pneumatic relieving mechanism is that the mobile of milling head main shaft is to be moved by the tooth bar on the cylinder piston in the prior art, sector gear is rotated and realizes.The machine driving automatic cutter relieving mechanism is by the set of gears transmission system in the prior art, the main shaft sliding sleeve is moved to be realized, hydraulic pressure automatic cutter relieving mechanism of the prior art is to drive main shaft and sliding sleeve when mobile backward to move backward together and realize automatic cutter relieving motion by the oil cylinder piston that is contained in the main shaft afterbody.The automatic cutter relieving mechanism of three kinds of patterns of summary all be the king post system automatic cutter relieving mechanism, thus have complex structure, make trouble, inconvenient maintenance, expensive problem.
In view of the problem that above-mentioned prior art exists, task of the present invention is a kind of simple in structure, good manufacturability of design, easy to use, cheap slabbing automatic cutter relieving mechanism.It has changed the relieving mechanism of king post system fully on basic structure, and automatic cutter relieving mechanism is arranged on the facing cutter, has simplified the milling machine structure so greatly.Particularly more favourable to the transformation of milling formula building-block machine.
The utility model is a kind of slabbing automatic cutter relieving mechanism that is used for field of machining, it is characterized in that installing one or more groups and can realize the Turable cutting cutter of automatic cutter relieving on improved facing cutter.When the bite of group more than being equipped with on the milling cutter disk body (2), one group of cutter finishing last processing is a Turable cutting cutter of realizing automatic cutter relieving, and all the other group bites are fixed bite, generally be installed in outermost layer and indexable cutter and form the ladder cutter, as shown in Figure 1 and Figure 2, the structure of slabbing automatic cutter relieving mechanism is for being assemblied in indexable cutter hub (18) in the mounting groove of milling cutter disk body (2) by bearing pin (10), push rod (11), spring (12), expansion screw (13), hold-down screw (1), adjustment screw (15) etc.Bearing pin wherein (10) is inserted in the indexable cutter hub (18) and is fastened on the milling cutter disk body (2) with hold-down screw (1), push rod (11), spring (12) are put in the side opening of milling cutter disk body (2) and and be screwed in the screwed hole of side opening expansion screw (13), to adjust screw (15) and be screwed on the indexable cutter hub (18), indexable cutter hub is by briquetting (17), housing screw (16) carbide cutting blade (14) to be fixed on the indexable cutter hub (18) with connecting of cutting tip.((2) upward the cutting edge of same group of indexable cutter are evenly distributed in same garden on week, and each blade tip is on same plane, and each quantity of organizing indexable cutter is more than one or one at the milling cutter disk body.Indexable cutter hub (18) can turn round certain angle around bearing pin (10) under the effect of spring (12), push rod (11), thereby makes indexable cutter point of a knife obtain certain amount of lifting.Fixedly the structure of bite is for being installed in fixed cutter body (5) in the installing hole of milling cutter disk body (2) by adjustment screw (3), cover plate (4), hold-down screw (6).At first fixed cutter body (5) is put into installing hole, adjust the position of fixed cutter body (5), at last that fixed cutter body (5) is fastening with hold-down screw (6) by the adjustment screw (3) on the cover plate (4) then.Carbide cutting sheet (9) is assemblied on the fixed cutter body (5) by briquetting (8), housing screw (7).
Slabbing automatic cutter relieving mechanism of the present utility model is equipped with automatic cutter relieving mechanism with the cancellation of the main shaft relieving mechanism in original technology on facing cutter.This mechanism all is located on the main shaft of milling head in Machine Tool design at present, thereby makes the milling head complex structure.The utility model on facing cutter, when machining finishes the back and cutter relieving automatically, thereby has omitted automatic cutter relieving mechanism design the relieving mechanism of main shaft, so has simplified the milling head structure.This automatic cutter relieving mechanism is a kind of comparatively ideal machining tool of field of machining, is specially adapted to the slabbing of building-block machine.Facing cutter of the present invention is housed realizes technological processes such as roughing or roughing, fine finishining or roughing, semifinishing, fine finishining.That this utility model has is simple in structure, easy to use, good manufacturability, advantage such as cheap, and use this invention can reach following some effect: (1) can solve the Milling Process withdrawing does not have the tool marks problem.(2) relieving mechanism of having simplified former milling head can reduce parts and expense 20～30%.(3) roughing, fine finishining are once finished and have been shortened work non-cutting time, can raise the efficiency 10～15%.(4) adopt ladder cutter machining can save cutting power 8～12%.(5) reduce tool wear, raising cutter life.(6) this slabbing automatic cutter relieving mechanism novel structure, have general use value.
The utility model has two accompanying drawings:
