Detailed description of the invention
As shown in Figure 1 and Figure 4, a kind of automatic loading and unloading system of numerically controlled lathe, is characterized in that: comprise mechanical system and control system, the bin 2 that described mechanical system comprises separated material device 1 and is arranged in separated material device 1, described bin 2 is built with charge bar 3, described separated material device 1 front end is connected with Pneumatic manipulator 11, described separated material device 1 rear end is connected with centre frame 12, there is the chuck 13 for blocking charge bar rear end, described centre frame 12 center by lathe main axis hole 4 docking, described chuck 13 rear end connects for detecting the switch 14 that charge bar whether puts in place, described switch 14 is connected with knife rest 15, described knife rest 15 is arranged on middle supporting plate 16, described middle supporting plate 16 is arranged on big palette 5, described knife rest 15 is provided with the lathe tool 6 for processing parts, described lathe tool 6 side-lower is provided with manipulator 8, described manipulator 8 symmetrical centre place is provided with rotating shaft 9, described manipulator 8 cutter side-lower is provided with the tote-box 10 for placing part 7, described control system comprises the CPU element, input block, output unit and the pulse unit that connect successively, described input block is connected with position switch, travel switch and control button by transmission unit, described output unit is connected with variable connector valve by transmission unit, described variable connector valve connects cylinder respectively, described pulse unit output is connected with multi-path stepping motor controller, and described multi-path stepping motor controller is connected respectively with stepper motor.
In the present embodiment, the promotion air pressure of described Pneumatic manipulator 11 is 0.2-0.3MPa.Air cylinder driven has the advantages such as structure is simple, cheap, use and maintenance is easy.But gas compressibility is large, regular tap controls difficulty makes piston be parked in optional position.Therefore, it can not send the bar of corresponding length to by any accessory size, but when piston top is by cylinder head (suitable mechanical link stopper), repetitive positioning accuracy is up to ± 0.03mm.We utilize the knife rest of numerically controlled lathe to make mechanical link stopper, Pneumatic manipulator is under the air pressure of 0.2-0.3MPa promotes, bar is made to pass lathe main axis hole and chuck hole is pushed up on knife rest and switch, rest position is by the size Control of CNC system for lathe processing parts on demand, thus realize feeding flexibility, pushing precision reaches ± 0.03mm, can save material and processing charges.
In the present embodiment, the piston rod top of described Pneumatic manipulator 11 there is also mounted journal bearing and end face bearing.Play supporting position-limiting action, bearing inner race can only be driven wherein when bar rotates to rotate, piston rod can not be caused to rotate.
In the present embodiment, three central frame rollers 122 that described centre frame 12 comprises three cylinders 121 and is connected respectively with described cylinder 121 are the lathe main axis hole 4 for clamping charge bar in the middle of described three central frame rollers 122.Lathe main axis hole periphery is distributed in hexagonal angle between three cylinders 121.
For preventing may producing violent oscillatory motion during the long bar of turning, a Pneumatic centering rack (as shown in Figure 2) is pacified at lathe head, Fig. 2 is the A direction view of Fig. 1, three cylinders are by same Air Valve Control, during air inlet, the rubber covered rollers of three piston rod parts compresses bar simultaneously, and rotate and rotation with bar, make bar be in lathe spindle center, thus prevent or reduce vibration.When piston rod stretches into the feeding of lathe main axis hole, rubber covered rollers can be pressed on the piston rod, play supporting role.When bar is machined into remaining dop, the control system of lathe makes knife rest retreat, and defective material falls into ash can, makes manipulator return original position simultaneously, is served by next root bar, gives lathe feed continuously.Each feed length with the need processing parts size and become, realize the requirement of material loading flexible automation.
When user undergoes technological transformation on original numerically controlled lathe production site, the place hour of installing feeding system can be used for, multi-stage cylinder or the cheap feeding system shown in common air cylinder group composite diagram 3 can be adopted, to shorten the length of feeding system.
As shown in Figure 1, because the diameter of part changes between Φ 10-Φ 25mm, length variations scope is larger.The moment that part cuts from bar by lathe tool, industrial robot can not capture part, has the intelligent robot also difficult crawl of the tracking fast part of hand eye coordination system.First we consider manipulator to be placed on the saddle of numerically-controlled machine tool rest, the change in location problem that lathe tool cuts part is followed the tracks of to solve, change the thinking that finger grabs part again, the part fallen after adopting mechanical hand for emulating human hand to connect cut-out from below, to adapt to the change of diameter of part and length dimension.For simplifying structure, reduction expense, using interlock during lathe tool cutting-off part, middle carriage installing a roller, when processing piece surface, in the process of lathe tool cutting-off part, roller on middle carriage advances, and makes the inloading part manipulator on saddle rotate under part gradually, just falls into wherein during cutting parts, when original position return by lathe tool, manipulator goes back to original position under the action of the spring, is discharged in tote-box by part.
When loading and unloading system comprises that a bar released by separated material device, Pneumatic manipulator sends forward bar to and return original position, all by the simple switch control rule of control system high-speed double electromagnet.Finger feed and lathe chuck open, clamping and lathe tool motion interlocking relation, its workflow is as follows: lathe startup → chuck opens → knife rest by input digital control system processing parts size motion to initial position → separated material device release a bar → manipulator send to forward bar → switch send bar put in place signal → lathe chuck clamping bar → processing parts → lathe tool cut part → knife rest by input digital control system processing parts size motion to initial position → chuck open → manipulator sends forward bar → switch to and sends the bar signal → lathe chuck that puts in place and clamp bar → by said procedure cyclic process, after a bar is processed → control system sends signal → manipulator and returns origin-location → separated material device and release next root bar → manipulator and send forward bar → circulate successively again.Unload part machinery hand to be driven by saddle and middle carriage, do not need control system to control.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure change, all still belong in the protection domain of technical solutions of the utility model.
