Description
Technical field
The present invention relates to field of machining, especially a kind of whirl wind cutting thread machine that is used to cut internal and external screw thread.
Background technology
Whirl wind cutting thread is a kind of method of advanced high efficiency machining screw; Be applicable to the production of the part big in batches, that required precision is higher; In process, can disposable completion cut; The surface quality of cutting is good, and institute's product processed mortality is little, so whirl wind cutting thread has higher efficient and quality with respect to present common tapping method.
Whirl wind cutting thread needs to accomplish five working motions in process: cutterhead drives carbide alloy moulding knife up speed rotation (main motion); Machine tool chief axis drives workpiece and rotates (synkinesia) at a slow speed; Whirlwind mills according to workpiece pitch or helical pitch along workpiece axially-movable (feed motion); Whirlwind mills radial motion (cutting movement); Whirlwind mills the free degree that in the certain angle scope, also has the lead angle adjustment.
But since present whirl wind cutting thread all need with the supporting use of lathe; Need be on lathe with clamping workpiece; Lathe control workpiece rotates and feed motion, therefore makes the workpiece of being processed restricted, can only the processing column body or the workpiece of cylindrical drum; Such as screw mandrel, and the trouble of the clamping workpiece on the lathe; Because workpiece rotates on lathe, unloads workpiece after workpiece such as needs stop operating, and causes the efficiency of loading and unloading of workpiece low; Since be supporting use, if workpiece needs many places processing, such as the two ends of processing work, so just need be through twice loading and unloading and twice feeding processing.
Therefore present whirl wind cutting thread has the some shortcomings part, and the range of work has significant limitation, can't be with its extensive use.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of whirl wind cutting thread machine is provided, and working (machining) efficiency is higher, and range of application is wider.
The present invention solves the technical scheme that its technical problem adopts: this whirl wind cutting thread machine, comprise workbench, and workbench is provided with body; Body is provided with knife bar; Be fixed with milling cutter on the termination of knife bar, wherein knife bar is fixed on the axle center of rotation main shaft, wherein is provided with the eccentric beam barrel that the rotation main shaft is installed in the body; Wherein the rotation main shaft is installed on the eccentric position in the eccentric beam barrel, and the rear end of rotation main shaft is passed eccentric beam barrel and is connected with spinning motor through gear-box; Wherein eccentric beam barrel is connected with the revoluting motor that drives its rotation; Wherein workbench is provided with cross slide way, and body is located on this guide rail, and on workbench, is provided with the screw mandrel that the control body laterally slides, and screw mandrel is connected on the revoluting motor, and wherein rotation main shaft, eccentric beam barrel all are installed on the body through drive end bearing bracket, rear end cap.This mechanism realizes the rotation of Whirlwind milling cutter, can cut; Through the rotation control knife bar revolution of eccentric beam barrel, circular motion is controlled Whirlwind milling cutter and is carried out around cutting within the specific limits; When eccentric beam barrel rotates; Revoluting motor drives the screw mandrel rotation and drives the Whirlwind milling cutter feed motion, through three different motion realization combining Whirlwind milling cutters workpiece is carried out screw chasing, need not workpiece and rotates or move; Only need workpiece be fixed and get final product; Therefore convenient, easy to the loading and unloading of workpiece, efficient is higher, and more main is the unrestriction to processing work.
Perfect for further, eccentric beam barrel is fixed with revolution gear outward, and wherein revoluting motor is connected with the transmission gear, wherein is in transmission connection through one-way clutch between revolution gear and the transmission gear, also is provided with the brake signal generator on the body.The effect of one-way clutch makes eccentric beam barrel one-directional rotation, eccentric beam barrel is added in the Whirlwind milling cutter feeding rotate man-hour, and when the Whirlwind milling cutter withdrawing, do not rotate; When Whirlwind milling cutter stops operating; The brake signal generator can be located the angle that Whirlwind milling cutter stops; Make the axle center position of Whirlwind milling cutter towards eccentric beam barrel; Whirlwind milling cutter can not touch workpiece in the process of withdrawing like this, avoids Whirlwind milling cutter in the withdrawing process, to cause Whirlwind milling cutter or workpiece to damage with the workpiece collision, thereby plays a protective role.
Screw mandrel is connected with the transmission gear drive, is provided with Norton gear mechanism between screw mandrel and the transmission gear.The rotation of screw mandrel and eccentric beam barrel all is connected the transmission gear; Therefore the speed of screw mandrel driving Whirlwind milling cutter feeding is corresponding with the velocity of rotation of beam barrel; Regulate screw mandrel and transmit the gearratio between the gear through Norton gear mechanism; Thereby the control screw mandrel drives the speed of Whirlwind milling cutter feeding and the velocity of rotation of beam barrel, promptly controls the pitch of Whirlwind milling cutter screw cutting.
Be provided with the eccentric adjusting beam barrel between rotation main shaft and the eccentric beam barrel, wherein the rotation main shaft is connected in the eccentric adjusting beam barrel through bearing shaft.The eccentric adjusting beam barrel is used to regulate the eccentric distance of rotation main shaft, therefore can process the internal thread and the external screw thread of different-diameter size.
Workbench is provided with longitudinal rail, and body is located on this longitudinal rail, and on workbench, is provided with the hydraulic cylinder that makes the body longitudinal sliding motion.This mechanism can control body and on workbench, vertically move, and the location is convenient in the position of scalable Whirlwind milling cutter.
The effect that the present invention is useful is: the present invention improves the whirl wind cutting thread technology; Need not supporting lathe uses; Also need not to rotate or travelling workpiece; Advantages such as only the need fixation workpiece can carry out screw chasing automatically, and the efficient of giving full play to whirling is high, crudy is good, and the assembling of workpiece is simpler.Not only range of application is wider for structure after this improves, and because workpiece is fixed, then can multiple devices processes many places or a plurality of end face of a workpiece simultaneously, and efficient is higher, and is with better function.This compact conformation, reasonable in design, overall volume is little, is convenient to carrying or transportation, and simple in structure, and low cost of manufacture helps extensive popularization.
