Description
Technical field
The utility model relates to a kind of cylindrical lathe, and especially a kind of multitool cylindrical lathe of graphite electrode belongs to the machining equipment technical field.
Background technology
Graphite electrode is the important Purchased Item of metal smelt industry.Because the graphite electrode material softness, bulky, machining accuracy is high, so process equipment is special, has only a few countries such as the U.S., Japan to make at present in the world.
Cylindrical turning processing is the second road critical process of graphite electrode processing after bore hole is wipeed operation off.The cylindrical machining accuracy of graphite electrode and fineness not only influence the clamping location of follow-up screw thread processing, and the serviceability of electrode is also had very important influence.Understand according to the applicant, existing equipment is with the characteristics long at electrode turning processing length, that external diameter is big at present, adopted the multitool method for processing, promptly several side by side the structure of lathe tool on lathe bed, but exist following: 1, a feed turning than open defect, do not divide smart, roughing tool, machining accuracy and surface smoothness not high (for example U.S.'s same category of device); 2, tool holder designs is reasonable inadequately, and the rigidity deficiency can only adopt the hydraulic drive location, and adjustability is poor, automaticity low (for example Japanese same category of device).
Summary of the invention
The purpose of this utility model is: the deficiency at above-mentioned prior art exists proposes the high electrode multitool cylindrical lathe of a kind of machining accuracy.
In order to reach above purpose, the main spindle box and the tailstock case that can push up the folder workpiece installed at the main bed ways two ends of the utility model electrode multitool cylindrical lathe respectively, the middle part install can be respectively along vertical, be parallel to following, middle slide plate that the bed ways direction moves, at least two tool rest brackets arranged side by side are installed on the middle slide plate, the rough turn knife rest of fixed installation on wherein said each tool rest bracket, roughing tool is installed on it, finish turning knife rest saddle is installed simultaneously, on it installation can be separately along the upper slide that moves perpendicular to main bed ways, and on upper slide, fixedly mount finishing tool.
Add man-hour, spindle motor drives the workpiece rotation by main shaft, at first cooperate and finish feed and feed action by following, middle slide plate, make roughing tool finish the rough turn processing of electrode cylindrical, then upper slide is done finish turning feed action, finishing tool touches surface of the work, in being parallel to the feed process of bed ways, finishes finish turning.Obviously, owing to the utility model has adopted the structure thick, that finish turning divides cutter, therefore effectively improved the precision of turning processing and the surface smoothness of electrode workpiece, and the rigidity of utilizing knife rest rational in infrastructure thick, the finishing tool packing, machining accuracy therefore further guaranteed.In addition, structure of the present utility model is also laid a good foundation for realization numerical control, raising automatization level.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the upward view (knife rest and dust arrester are not shown) of Fig. 1.
Fig. 3 is the A-A cutaway view Amplified image of Fig. 1.
The specific embodiment
Embodiment one
Basic structure such as Fig. 1, Fig. 2, shown in Figure 3 of the electrode multitool cylindrical lathe of present embodiment, main spindle box 2 and the tailstock case 7 that is holding out against under hydraulic motor 8 and the 8 ' drive respectively, can move top folder workpiece 4 along bed ways is installed at the guide rail two ends of main lathe bed 5, the main shaft of main spindle box 2 is driven by polywedge bet 1 by main motor 3, main lathe bed 5 middle parts be connected as a single entity perpendicular to the knife rest lathe bed 14 of main lathe bed 5, lower skateboard 19 is installed above, and lower skateboard 19 constitutes the lower skateboard delivering gear with the leading screw and nut mechanism that drives by servomotor 13.Middle slide plate 12 is installed on the parallel guide rail of lower skateboard 19 upper surfaces and main lathe bed 5, and constitutes the middle slide plate delivering gear with the leading screw and nut mechanism that drives by servomotor 18.Four tool rest brackets arranged side by side 20 are installed on middle slide plate 12, fixedly mount rough turn knife rest 21 on each tool rest bracket side by side, install one on it roughing tool 15, simultaneously at the finish turning knife rest saddle 22 of tool rest bracket 20 upper surfaces installation perpendicular to main lathe bed 5, install slide plate 11 on it, upper slide 11 and leading screw and nut mechanism by servomotor 17 constitute the upper slide mechanism that progresses greatly, fixed installation finishing tool 16 on upper slide 11.
Drive motors is servomotor because lower skateboard 19 delivering gear drive motors 13, middle slide plate 12 feed drive motors 18, four upper slides 11 progress greatly, so the electrode multitool cylindrical lathe of present embodiment has adopted Numeric Control Technology.Under programme-control, graphite workpiece 4 is under the driving of hydraulic motor 8 and 8 ', after being clipped by main shaft and tailstock top, by spindle motor 1 driven rotary, then under motor 13 drove, lower skateboard 19 was sent four on the middle slide plate 12 to roughing tool 15 to, more then under motor 18 drives, middle slide plate 12 feed campaigns make four roughing tool 15 segmentations finish the rough turn processing of electrode cylindrical.After this, four upper slides 11 are done finish turning feed action under the driving of separately drive motors 17, and the finish turning of outer round surface is finished in then middle slide plate 12 reverse feeds.Experiment showed, that above process finishes automatically under programme-control, accomplish without any letup, efficient height not only, and got rid of artificial factor, control accuracy height, steady quality.
In addition, the helical feed dust arrester 10 that is driven by motor 9 is equipped with in the lower skateboard below in the present embodiment, and dust exhaust apparatus all is housed in each tool rest bracket.This device can be got rid of graphite bits and the dust under the car at any time.
In a word, the lathe of present embodiment has following outstanding advantage:
1, rationally adopts the structure thick, that the finish turning multitool divides cutter, therefore effectively improved the precision of turning processing and the surface smoothness of electrode workpiece;
2, down, in, upper slide structure and thick, smart cutter fixed position reasonable in design, therefore good rigidly has further guaranteed machining accuracy;
