Description
Technical field
The height-adjustable lathe tool of the described swinging of the utility model relates to a kind of lathe with big helical pitch Corkscrews accessory turning cutter.
Background technology
When turner is installed lathe tool, aim at the alignment of shafts in order to make point of a knife, accomplish through adjusting lathe tool height.Regulate the lathe tool height, generally use the pad of different-thickness, pad is adjusted pretty troublesomely between lathe tool knife bar and lathe saddle, is difficult to find suitable pad sometimes.Too many or the out-of-flatness of pad number, not alignment (unsettled or empty pad is arranged) each other can make the reduction of lathe tool rigidity and produce bigger vibration, influences workpiece surface roughness, even cutter can occur gnawing.At the big helical pitch Corkscrews part of processing, as: when square thread, trapezoidal thread, worm screw, the workpiece lead angle is bigger usually; During processing right hand helix class part, need wear into the front clearance in cutter left side the angle of " lead angle of workpiece+3～5 ° ", the front clearance on the left of like this is bigger; Rigidity, the intensity of cutter weaken; Vibrations when processing work, often occur or gnaw the cutter phenomenon, the processing work precision is difficult to guarantee, influences the workpiece crudy.
To existing problem in the above-mentioned prior art, the height-adjustable lathe tool of a kind of novel swinging of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of the utility model is the height-adjustable lathe tool of a kind of novel swinging of research and design.In order to what exist in the solution prior art: 1, tool setting speed is slow; 2, the lathe tool integral rigidity bad, cutter appears gnawing; Problems such as 3, cutter shakes, and surface of the work is coarse, form of thread is incorrect.
In order to reach fast, accurately regulate the lathe tool height; Make point of a knife aim at the alignment of shafts, the utility model provides a kind of lathe tool that can regulate height, adopts the eccentric bushing structure; Through the rotating eccentricity cover lathe tool knife bar is moved up and down, guarantee that point of a knife fast, accurately aims at the alignment of shafts.For rigidity and the intensity that improves lathe tool, take rotary structure, rotate corresponding angle according to the size of part lead angle, fix with trip bolt then, reduced the grinding relief angle of lathe tool.In order to reduce the influence of vibrations to workpiece, the front end of revolution blade is equipped with two damping resilient sleeve.Make the cutter integral rigidity good, prevent and gnaw cutter, influence workpiece surface roughness, process quality issue such as the cutted thread tooth form is incorrect.
The technical solution of the utility model is achieved in that
The height-adjustable lathe tool of the described swinging of the utility model is made up of lathe tool piece, revolution blade, square cutter hub seat and eccentric bushing; The front end that it is characterized in that described revolution blade is equipped with the lathe tool piece, and fixes through lathe tool piece fastening bolt; Insert in the eccentric bushing at the rear portion of revolution blade, and fastening through the knife bar trip bolt; Flying knife is equipped with two elastic shock attenuation covers on one's body; Eccentric bushing is contained in the square cutter hub seat, and through the dog screw location; The front end of square cutter hub seat has turning slot, will turn round blade through the blade trip bolt and be loaded on the square cutter hub seat.
One side of the described square cutter hub seat of the utility model is processed with the gap of 1-4mm; Square cutter hub seat rear portion is processed with blade rotation scale; The top of the anterior turning slot of square cutter hub seat is processed with datum line.
The described flying knife of the utility model is in be processed with revolution blade rotation scale near square cutter hub seat top.
One side of the described eccentric bushing of the utility model is processed with the gap of 1-4mm, and the rear portion of eccentric bushing is processed with 8 circular holes and a datum line, and eccentric bushing can rotate in square cutter hub seat.
The described revolution blade of the utility model can rotate in turning slot limited field (± 30 °) scope.
Unclamp knife bar fastening bolt, blade trip bolt, dog screw during use earlier; Lathe tool point of a knife and the high difference of the alignment of shafts according to measurements and calculations; Insert rotating eccentric sleeve in the circular hole at rear portion of eccentric bushing with pole; The rotation of eccentric bushing drives flying knife lathe tool piece on one's body and adjusts the position up and down, and the blade adjustable height scale on the corresponding square cutter hub seat of the datum line on the eccentric bushing is promptly known the distance of lathe tool piece relative displacement.The screwed in place screw reached the effect of adjusting the lathe tool height fast and accurately after adjustment finished.Cutting-tool angle according to the need rotation of calculating; Rotate the revolution blade to corresponding angle index value, fastening blade trip bolt, knife bar fastening bolt reach under the situation of not reconditioning cutter front clearance; The convenient cutting-tool angle of adjusting accurately; To reduce the excessive vibrations that cause of front clearance, improved operating efficiency, guarantee the crudy requirement of workpiece.Two shock-absorbing sleeves are equipped with in the front portion of revolution blade, absorb to add the vibrations that man-hour, impulsive force caused; Eccentric bushing can rotate in square cutter hub seat, so that the rapid adjustment center cutter is high.
The utility model has the advantages that conspicuously, mainly show:
1, owing to used the utility model, improves tool setting speed, saved the time, improved efficient;
2, owing to used the utility model, improve the stability and the rigidity of lathe tool, avoided gnawing the generation of cutter phenomenon;
3, owing to used the utility model, eliminate the influence of vibration, improved machining accuracy, avoided that work piece surface is coarse, form of thread is incorrect processing work.
