Abstract
The utility model belongs to the lathe cutter specifically is a just, anti - integral type boring cutter. The problem of with the unable processing of current cutter when processing 2600kw coal -winning machine pulls the case with the rocking arm is solved, a just, anti - integral type boring cutter, includes boring cutter, fixed screw, tool bit, cutter arbor and handle of a knife, is connected with the one end of cutter arbor on the handle of a knife, and the cutter arbor other end is connected with the tool bit, and tool bit bottom is equipped with the recess, and the recess internal fixation has a boring cutter, the lateral wall of recess of tool bit bottom open and have a plurality of screw holes, the boring cutter passes through fixed screw and tool bit fixed connection in the screw hole. The utility model discloses prove at current coal -winning machine rocking arm and the processing technology in -process that pulls the case that this cutting tool system has not only improved production efficiency, also improved manufacturing's quality simultaneously, reduced manufacturing cost.
Description
Technical field
This utility model belongs to machine tool, a kind of positive and negative integrated boring cutter.
Background technology
The main machining method of machine-building, particularly modern manufacturing industry is machining.Comprising hardware and software two class key element in cutting processing system, hardware system includes lathe, cutter, attaches, and software system includes kinetic control system, detecting and controlling system etc..In hardware system, cutter is minimum, and input ratio lathe is much smaller, but cutter is the most versatile and flexible, the most notable to crudy, efficiency, cost impact.Be good at reform cutter, tend to obtain the effect got twice the result with half the effort because reform cutter with change lathe, fixture compared with, put into little, effect is big, the cycle is short, instant effect.Ancients say " a workman must first sharpen his tools if he is to do his work well ".Cutter is the direct executor that lathe realizes machining, does not has cutter, and lathe just cannot work.For burr of shearER element processing characteristic, the design of dedicated tool necessarily requires enough precision, advanced structure, gives full play to the internal potential of cutter, reach the purpose of high-quality, high yield.
My company is when processing 2600kw drawing box for coal cutter with rocking arm, ear's dimension of emptiness is R300 and R240, ear hole is that Φ 260 and Φ 240 is so when anti-stroke of mid-plane, cutter is monolateral stretch out that effective length is minimum need to be 170 and 120, cannot process with existing cutter, for processing difficulties at this, this set tooling system designed and produced.
Like parts added man-hour in the past, use one No. three lengthening offset tool (20 × 20 × 240) processing of Φ 90 boring cutter bar cramp, work in-process only has 20 × 20 owing to cutter stretches out the cutter side about 150, so in the course of processing, cutter rotating speed and feeding all can not be excessive, and easily produce vibration and collapse cutter phenomenon, processing a room probably at 6-8 hour, cutter uses needs 6-10 No. three lengthening offset tools.Cumbersome and time consuming, and machining accuracy can not be effectively guaranteed.
Summary of the invention
This utility model is for the problem solving cannot process with existing cutter when processing 2600kw drawing box for coal cutter with rocking arm, it is provided that a kind of positive and negative integrated boring cutter.
This utility model takes techniques below scheme: a kind of positive and negative integrated boring cutter, including boring cutter, fixed screw, cutter head, knife bar and handle of a knife, connect on handle of a knife and have one end of knife bar, the knife bar other end is connected with cutter head, groove it is provided with bottom cutter head, being fixed with boring cutter in groove, the sidewall of the described groove bottom cutter head has some screw holes, and boring cutter is connected by the fixed screw in screw hole and cutter head are fixing.
Compared with prior art, this utility model proves in the machining process of existing rocker arm of coal mining machine and towing tank, and this tooling system not only increases production efficiency, also improves the quality of processing and manufacturing simultaneously, reduces production cost, is deeply welcome by workman.And the present invention can be widely used on the multiple coal-winning machine that China is domestic, has good practical value.The most probably needing within 3-5 hour, saved than ever 2-3 hour when processing hinge hole room, and cutter can save 3-5 cutter, so get off to save about 12 hours one rocking arm (4 times rooms) of processing, cutter can save about 15.

Detailed description of the invention
As shown in Figure 1, a kind of positive and negative integrated boring cutter, including boring cutter 1, fixed screw 2, cutter head 3, knife bar 4 and handle of a knife 5, connect on handle of a knife 5 and have one end of knife bar 4, knife bar 4 other end is connected with cutter head 3, is provided with groove bottom cutter head 3, is fixed with boring cutter 1 in groove, the sidewall of the described groove bottom cutter head 3 has some screw holes, and boring cutter 1 is connected by the fixed screw 2 in screw hole is fixing with cutter head 3.
Described cutter head 3 is provided with the notch for being connected with knife bar 4, and knife bar 4 is arranged in notch, and bottom cutter head 3, corresponding notch position has bolt hole, and knife bar 4 is connected by the bolt in bolt hole with cutter head 3.
