Abstract
A tool rest for turning crankshaft main-shaft diameters belongs to lathe accessories, and is characterized in that a tool disk is a regular polygon post body of which the middle has a through-hole, each lateral face of the regular polygon post body of the tool disk is mounted with an acceptance device, a knife bar is mounted on the acceptance device, and a knife tool is mounted on the knife bar. The tool rest has the advantages of non-need for changes after the knife tool is primarily mounted and clamped, being capable of ensuring the continuity of turning, enhancing the processing quality, large bearing capability of rests, high rigidity, good shock-absorbing, enhancing the quality of work-pieces, reducing the worker labor intensity and increasing the production efficiency.
Description
Technical field
The utility model belongs to machine tool accessories, and particularly a kind of turning crank spindle is directly used knife rest.
Background technology
At present, traditional lathe is when turning crank spindle footpath, usually adopt traditional frame knife rest, two cover knife plates are installed are carried out turning, because the particularity of crankshaft type part during turning crank spindle footpath, must make the knife bar extension elongation greater than turning the footpath degree of depth, otherwise, can be subjected to restriction and interference that bent axle turns the footpath.The traditional approach knife bar length that overhangs that generally can extend; greatly reduce the rigidity of cutter like this, when turning, be easy to take place the knife bar vibration; particularly original knife rest can only two cutters of clamping; during the different surface of the work of turning, need frequent tool changing, workpiece does not reach specification requirement; qualification rate reduces; cutter changing rapid increased processing cost, reduced productivity ratio.
Summary of the invention
The purpose of this utility model provides a kind of rigidity height, and absorbing is good, and No. one time the many turning crank spindles cutter of clamping are directly used knife rest.
The solution that realizes the purpose of this utility model is to comprise knife bar 3, receiver 2, particularly cutterhead 1 are the middle regular polygon cylinders that through hole is arranged, and in each side of cutterhead 1 regular polygon cylinder a receiver 2 are installed all, knife bar 3 is installed on the receiver 2, on the knife bar 3 cutter is installed.
The regular polygon cylinder of cutterhead 1 is the hexagon cylinder at least.The limit of cutterhead 1 intermediate throughholes is provided with installing hole 4.
After the utility model has the advantages that clamping cutter, in turning process, do not need to change, can guarantee the continuity of turning, improve crudy; Bearing capacity is big, the rigidity height, and absorbing is good; By interior circulation cooling duct, cutting fluid can be transported to cutting zone, in use play lubricated cooling effect, reduce the thermal deformation of workpiece greatly, thereby guarantee the precision and the surface roughness of workpiece.Improved the quality of workpiece, alleviated labor strength, boosted productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of cutterhead.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Cutterhead 1 is the middle regular polygon cylinder that through hole is arranged, at least be the regular hexagon cylinder, can be the octagon cylinder as required, dodecagon cylinder or the like, cutterhead 1 has through hole in the middle of being, installing hole 4 is arranged on the through hole limit, all process a locating hole 5 that receiver 2 is installed in each side of cutterhead 1 regular polygon cylinder, four screwed holes, a cooling-lubricant outlet, receiver 2 is fixed on the cutterhead 1 by four screws, and knife bar 3 is installed on the receiver 2, receiver 2 is can Fast Installation and unload the device of knife bar 3, on the knife bar 3 cutter is installed.Cutterhead 1 is under the prerequisite that does not influence rigidity, and thickness can be wide less than the shelves of bent axle, and cutterhead 1 enters in the main shaft diameter shelves with knife bar 3 one like this, can expand the range of work
During use, cutterhead 1 is connected with lathe cutter tower by installing hole 4, by lathe cutter tower driven rotary, conversion processing stations.Cooling-lubricant exports, flows on the cutter through receiver 2, knife bar 3 by the cooling-lubricant of pump on cutterhead 1.All cutters according to workpiece size selection needs are installed on the cutterhead successively, as left avertence cutter → middle circular arc cutter or sharp knife → right avertence cutter, by the different cutter of conversion, finish whole working angles.Until finishing all crank spindle footpaths, fillet, crank arm etc.This knife rest is also applicable to all kinds of axle classes, dish class simultaneously, but the various cylindricals of turning, end face, tapering, screw thread, circular arc and revolving body curved surface.
According to the workpiece processing technology, manually the station of conversion cutter also can be used for numerically controlled lathe, writes program, by the station of numerical control program control knife rest.
