Detailed description of the invention
Below in conjunction with accompanying drawing, the architectural feature of the cooling device of drawing mould of the present invention is described in detail, so that the technology of the present invention innovation effect clearly shows that.
It is contemplated that propose the rotary index device of a kind of Tool Magazine in Machining Centers, solve the accuracy of broach shell rotary index switching.
From the point of view of traditional machining center device, tool magazine is provided with cutterhead, numerical control unit and cutterhead sensor for countering, and cutterhead is mechanically coupled with motor shaft, and cutterhead sensor for countering accesses numerical control unit, and numerical control unit output connects the motor (not shown) controlling tool magazine rotation.And tool magazine is made improvements by this creation, this Tool Magazine in Machining Centers arranges machinery and electrically jointly controls the rotary index device that tool magazine standard is stopped, specifically, this rotary index device is provided with and guides the brake clutch dish 4 being connected to motor shaft 5, the solenoid of DC90V it is arranged with on motor shaft, solenoid accesses the operating voltage of motor and controlled break-make in numerical control unit by Transformer Rectifier circuit, solenoid is provided with the top containing some springs towards the side of brake clutch dish and stretches plate, the driven fixed disk friction stretching plate and motor housing in top under solenoid power failure state of described brake clutch dish touches, spline motor shaft, and departed from fixed disk by more than the magnetic adsorbability of spring force under solenoid obtains electricity condition, motor shaft rotates freely.
As shown in Figures 4 to 7, this motor shaft 5 sleeve integrating is provided with profile of tooth guide rail 51, and this brake clutch dish 4 axle portion is provided with mates, with profile of tooth guide rail 51, the perforation 41 engaged.
Stretch as prioritization scheme, solenoid and top and be provided with six springs between plate and be uniformly distributed along card.Solenoid is provided with lead in corresponding spring side, and top is stretched plate and is provided with gap, and gap is socketed on lead and slides along lead.
The application of this creation rotary index device, after the indexing threephase asynchronous once dead electricity of tool magazine, makes motor brake at once by the quasi-stop device of this mechanical electric, is embraced by motor shaft " inflexibly ", eliminates inertia.
nullGeneral principle is as follows: when normal tool changing，Tool magazine motor three-phase electricity obtains electric，Simultaneously the solenoid in electromagnetic clutch also electric generation magnetic force，Brake clutch dish is adsorbed by the elastic force overcoming spring，Now brake clutch dish disengages with the fixed disk on motor，I.e. brake clutch dish and fixed disk does not produce any friction，Tool magazine motor is rotatable，Following cutterhead mechanical part is driven to rotate，After cutter claw needed for arrival，Cutterhead sensor for countering allows tool magazine motor three-phase electricity dead electricity to one instruction of digital control system，The solenoid being both in electromagnetic clutch also dead electricity、Lose magnetic force，Brake clutch dish is pushed back by the elastic spring in electromagnetic clutch，Make together with brake clutch dish rubs inflexibly with fixed disk，Now motor shaft is locked，Eliminate the inertia of its stall，Cutterhead stops operating at once，Cutter claw captures broach shell in correct position.
Because the solenoid in electromagnetic clutch needs the voltage of DC90V-100V, and tool magazine motor is three-phase electricity 380V, because motor is Y-connection, we have thought that a method is from having taken a 220V alternating voltage (380V is divided by 1.732=220V) between any one phase and neutral point, then by a single-phase half-wave rectifier circuit (as shown in Figure 8), this AC rectification is become about DC99V, the feature of this circuit be exactly this voltage must with lose with three phase electric machine three-phase electricity must with lose be Tong Bu, it is ensured that the accurate stop position of cutterhead.Wherein, D1 is commutation diode, starts unidirectional halfwave rectifier effect, C1 Yu C2 is filter capacitor, and YC is solenoid, and D2 is the fly-wheel diode eliminating solenoid YC inverse electromotive force.
The development of rotary index device of the present invention and application, the advantage comparing to conventional knives library structure prominent is embodied in: the program solves the traditional shortcoming of tool magazine rotary index, substantially reduce the fault rate of automatic tool changer, improving the service life of tool magazine, the production efficiency of machining center is also substantially improved.
Embodiment above in association with accompanying drawing describes, it is intended to readily appreciate the innovation essence of the present invention, but the embodiment not limiting its versatility with this and the claims of requirement.In every case understand the present invention, and the equivalent structure change or the component that carry out according to above-described embodiment are replaced, it is possible to realize the design of identical purpose and effect, be regarded as the infringement to present patent application protection content.
