Abstract
An economic horizontal digital control cutter frame comprises a proximity switch (1), a code device (9) and a gear shaft (12). The utility model is characterized in that a motor (10) connects with a screw (6) through a gear pair. The screw (6) connects with a locking disc (4). The locking board (4) meshes with a movable fluted disc (3) and a fixed fluted disc (2). A center shaft connects the locking disc (4) through the screw (6). The movable fluted disc (3) connects an adjusting-loading cutter head. The lower part of a primary positioning pin (5) cooperates with a positioning groove of a primary positioning disc (7), and the upper part cooperates with a combining branch notch. The economic horizontal digital control cutter frame researches and develops on the basement of continuously improving and perfecting the structure of the horizontal digital controller cutter frame. The economic horizontal digital control has the characters as follows: the volume of the cutter frame is small, and the structure is compact. The rigidity is favorable. The displacement coefficient and the rotating ratio are increased. The economic horizontal digital control cutter frame can choose the knife in a single-directional multi-station way automatically, and it can accomplish turning, drilling, boring and other cutting processing. The toe index is fast, and positioning accuracy is high. The impact is small, and the operation is stable. The focal point of stress of an electric cutter frame main shaft is improved. The dependability is high, and the malfunction rate is low. By adopting a moment motor, the problems such as inadequate tight force of ordinary motor lock and burning the winding can be solved.
Description
Technical field
The utility model relates to the horizontal digital-control knife rest that numerically controlled lathe uses, particularly can the unidirectional automatically cutter that selects, by the installation six of end face cutter groove lathe tool, but three boring cutter seat clampings three of configuration are the Economy horizontal numerical control cutter saddle of hole machining tool.
Background technology
The horizontal digital-control knife rest that existing domestic numerically controlled lathe uses, basically be the digital control system of coming the feedback position signal by the electric device that is installed on the numerically-controlled slide body, the action command that sends release, transposition, location, locking to executing agency is finished the action of mechanical part.After knife rest obtains selecting the cutter instruction, through worm screw, helical gear and screw mandrel rotate, nut and active toothed disk are moved backward, with the out-of-gear while of fluted disc, the trundle of the plane of the edge cam of zygote through being fixed on the active toothed disk drives main shaft and cutterhead rotation, when forwarding the preliminary election cutter spacing to, near switch, magnetic patch sends signal, the motor counter-rotating drives the zygote counter-rotating, zygote upper surface cam enters in the locating slot under the effect of spring through first alignment pin, and cutterhead can not rotate, and screw mandrel continues counter-rotating moves forward active toothed disk, realize the locking of location and cutterhead, this moment, bar entered under the effect of spring in the circular trough of active toothed disk, and dish piezomagnetism switch sends power cut signal, time-delay, the motor outage, so far knife rest is finished tool changing action.Numerically-controlled slide is operated in the worst environment of numerically controlled lathe, and heat conduction of the frequent transposition of the vibrations of cutting, knife rest, tool changing, working angles etc. requires numerically-controlled slide to have high-strength comprehensive mechanical performance.There is following shortcoming in the use of existing horizontal digital-control knife rest:
1. transposition is slow, causes productive temp slow, and efficient is low.
2. shock resistance is poor in the working angles, and poor rigidity shows that mainly the presentation quality of processing parts is poor, and the demanding part of process technology does not reach the drawing specification requirement.
3. knife rest outward appearance volume is big, and it is big to take up room.
At present, domestic horizontal digital-control knife rest majority is the worm and gear transmission, adopts Modified Gear Transmission, and the numerically-controlled slide that the mode of increase gearratio is produced does not still have.
The utility model content
The purpose of this utility model is at the prior art defective, and a kind of volume is little, precision is high, transposition is fast based on providing economically, antidetonation, shock resistance is strong, fault rate is low Economy horizontal numerical control cutter saddle.
Economy horizontal numerical control cutter saddle, comprise near switch 1, encoder 9 and gear shaft 12, it is characterized in that motor 10 is connected with screw rod 6 by gear pair, screw rod 6 is connected with locking plate 4, locking plate 4 is meshed with active toothed disk 3 and fixed tooth disk 2, and central shaft is connected with locking plate 4 by screw rod 6, and active toothed disk 3 links to each other with transferring the dress cutterhead, just alignment pin 5 bottoms cooperate with the locating slot of first positioning disk 7, match with the zygote notch in top.
Its operation principle is as follows:
The knife rest motor begins just to change after receiving the tool changing instruction of control system, pass to screw rod by gear pair, screw rod and the engagement of locking plate internal thread, driving central shaft just changes, the drive locking plate rises, when motor is just forwarding that control system sets to very first time during section fluted disc break away from engagement, wait for transposition: second time period (judging that by digital control system the figure place of will changing a job calculates automatically) that motor continues just changeing executive control system drives central shaft by screw rod is just changeed, drive active toothed disk and cutterhead are just changeing the execution knife rest and are selecting the swivel bit motion, cutterhead was just forwarding assigned address to when second time period finished, and control system is sent the motor stop instruction; Send motor counter-rotating instruction then, motor begins counter-rotating and carried out for the 3rd time period, at this moment drives the central shaft counter-rotating by screw rod, the drive locking plate descends, make fluted disc enter engagement, fluted disc is finished the knife rest location action to mesh fully when the 3rd time period finished, and finishes once complete tool changing action.
Economy horizontal numerical control cutter saddle is the economical nc knife rest of updating at the horizontal digital-control cutter frame structure to other products, researching and developing out on the perfect basis.Have following characteristics:
1. little, the compact conformation of knife rest volume, rigidity are good.Utilize traditional gear drive principle, add the modification coefficient of gear wheel, increase gearratio.Simultaneously, select cutter by automatic unidirectional multistation, can finish car, brill, boring, etc. complicated machining, become and repeatedly be installed to once being installed, guarantee zero, the component processing precision.
2. transposition is quick, positioning accuracy is high.Impact little, running steadily.By finite element analysis to the numerical control cutter frame structure, improved the enhancing gusset of electric driving tool post body, improved electric driving tool post main shaft stress concentration point.
3. reliability height, fault rate are low.The reliability of the reliability decision Digit Control Machine Tool of numerically-controlled slide, to the reliability consideration of multi-station electric knife rest, knife rest pre-determined bit mechanism is reliable.Adopt torque motor transmission locking, it is not enough to have solved the common electric machine coupling mechanism force, burns the problem of winding.
