Description

The adjustable endoporus finishing tool of machinery folder
Technical field
The utility model relates to a kind of cutter, is specially the adjustable endoporus finishing tool of a kind of machinery folder.
Background technology
In machining industry, carry out endoporus and add man-hour used cutter and be generally brazed shank tool, promptly knife bar and cutter head are welded as a whole.And at manufacturing enterprise's mechanical processing industry attached, non-batch process, processing work size difference, non-batch machining, need according to production maintenance, the relevant processing dimension of the workpiece that receives is different to be occurred at random, when using above-mentioned traditional welding fabrication cutter machining internal thread workpiece, its flexibility, poor practicability, defective mainly shows following several respects: 1. in process, sharpening to cutter, knife bar and cutter head are worn away simultaneously, cutter head mill back knife bar is to the greatest extent scrapped simultaneously, and utilization rate is low; When 2. processing the different depth endoporus, need the cutter of sharpening different length knife bar and change, need that reserve tools quantity is big, the sharpening workload is big, the cutter waste is big, change that the cutter workload is big, inefficiency for guaranteeing machining accuracy; 3. for guaranteeing machining accuracy, the control depth of cut, change angle, cutter head front and back, cutting edge inclination difficulty, working (machining) efficiency is low.
Summary of the invention
The utility model is in order to solve the mechanical processing industry attached, non-batch process in manufacturing enterprise, when processing, adopts interior hole workpiece traditional welding type cutter, have that knife bar, cutter head utilization rate are low, very flexible, poor practicability and cause problems such as working (machining) efficiency is low, time-consuming, provide a kind of machinery folder adjustable endoporus finishing tool.
The utility model is to adopt following technical scheme to realize: the adjustable endoporus finishing tool of machinery folder, the fan-shaped cutter head that comprises tool rest, knife bar and be positioned at knife bar one end, have knife bar installation through hole in the tool rest and along its axial direction, the tool rest top has at interval with knife bar the knife bar positioning spiro pit that through hole is communicated with is installed, and is inserted with the positioning threads pin in the knife bar positioning spiro pit; Knife bar runs through and is arranged in the tool rest, is interval with the annular radial locating slot that cooperates with the positioning threads pin ends on the knife bar and along its axial direction; Knife bar one end is obliquely installed the cutter head fixed axis, and cutter head fixed axis lower end has clamp groove, and fan-shaped cutter head is positioned at clamp groove, on the knife bar and be positioned at clamp groove one side the housing screw that holds out against with the clamp groove cell wall is housed.
On the described knife bar and be positioned at cutter head fixed axis one side the dog screw that holds out against with the cutter head fixed axis is housed, can play positioning action, guarantee that cutter head is stable the cutter head fixed axis; On the described knife bar and the other end relative with fan-shaped cutter head have the cutter head housing screw that cutter head is installed through hole and played the role of positioning, low speed steel or white steel knife head can be installed in this cutter head installing hole, and with the cutter head housing screw it is held out against in its side, like this, the knife bar two ends can be installed different cutter heads respectively, the direction that only need adjust knife bar during use gets final product, and has further enlarged the scope of application of this cutter; On the knife bar and be positioned at the groove that endwisely slips that each positioning threads pin lower end has perforation, slide before and after in the knife bar installing hole of knife bar at tool rest, when regulating effective active length of knife bar, positioning threads pin ends sliding tray vertically moves; The tool rest below has the axial mounting groove that cooperatively interacts with lathe, is convenient to whole cutter positioning is compressed on lathe and with tool rest and knife bar.
Compare with traditional welding type cutter, the utlity model has following advantage:
1, knife bar can the knife bar installing hole in tool rest in before and after slide, make knife bar length satisfy under the prerequisite of requirement on machining accuracy, realize adjustable;
2, cutter head and knife bar flexibly connect by cutter head fixed axis, housing screw, dog screw, Stability Analysis of Structures, simple, and cutter head is easily changed, and the cutter head basil is rotatable recycles, and knife bar is reusable;
3, cutter head can be adjusted in the knife bar end, and tool inclination angle is changed, and it is stressed good to cut, and working angles is steady, and the machined surface roughness precision obviously improves; Because cutting edge inclination increases, reduce cutting resistance and cutting deformation; The edge of a knife can rotate in cutter hub, and center cutter height, cutting edge inclination, anterior angle, relief angle can be adjusted, and is easy to preferably arrive the optimal process angle;
4, the cutter head of different purposes is equipped with at the knife bar two ends respectively, only need adjust the direction of knife bar, can process different holes, has further enlarged the scope of application of this cutter;
In a word, use cutter described in the utility model, prolonged the service life of cutter, reduce the deposit kind of cutter, reduce production costs, expection will make the kind of existing cutter reduce 10 kinds, and the life-span of cutter extends to two months by present average two weeks, can save a large amount of expenses every year thus, simultaneously, working (machining) efficiency can be brought up to original two to three times, reduce working strength of workers, have certain popularization value.
