This hollow electromechanics clamping device uses motor to drive disc spring gland by lead screw transmission mechanism and lever transmission mechanism
Motion, adds the resilient force of disc spring group in disc spring group assembly, makes trombone slide Axially moving belt move collet clamping or pine
Go into operation part, it is achieved that substitutes traditional, pneumatic, hydraulic-driven or pneumatic and hydraulic-driven Dual Drive by motor-driven mode
Mode.Use motor as power source, it is not necessary to being separately provided air supply system or oil supply system, more energy-conserving and environment-protective, reduce into
This.
In above-mentioned hollow electromechanics clamping device, described lead screw transmission mechanism includes that inside has the base of installing hole,
Described motor is fixed on base, is provided with shaft coupling, screw mandrel and ball head in described installing hole, and the output shaft of described motor is stretched
Being connected with one end of screw mandrel in entering installing hole and by shaft coupling, the other end of described screw mandrel is joined by screw-driven with ball head
Closing, described ball head is circumferentially positioned also by the guide pad on base.Motor output shaft drives screw mandrel to rotate by shaft coupling, leads
Limit the circumferential movement of ball head to block, make ball head move along a straight line, it is achieved that the rotation of motor output shaft is converted into
The linear motion of ball head.
As preferably, in above-mentioned hollow electromechanics clamping device, in described installing hole, it is provided with bearing one, described screw mandrel
On be threaded connection a locking nut, described locking nut is resisted against on the end face of bearing one.Screw mandrel is risen by locking nut
To axial limiting effect so that the rotation of screw mandrel is the most steady.
In above-mentioned hollow electromechanics clamping device, described lever transmission mechanism includes that shift fork, described disc spring gland stretch out
The part of installation cavity is arranged with bearing two, described disc spring gland the inner have for bearing two against butting section, described bearing two
Outer ring sleeve be provided with and stir ring, described in stir the outer ring tight fit of ring and bearing two, described base has yoke bracket, described
The middle part of shift fork is hinged on above-mentioned yoke bracket and forms the fulcrum that shift fork rotates, and one end of described shift fork connects knot by bulb
Structure is connected with ball head, and the other end is hinged on to be stirred on ring.Shift fork by stirring annulus dynamic bearing two axially-movable, bearing interior
Circle and disc spring gland end contact drive the motion of disc spring gland, now disc spring gland along with main axis can the inner ring of band dynamic bearing
Relative to outer ring rotating, and make to stir ring and shift fork keeps static；After shift fork resets, the inner ring of bearing not with the end of disc spring gland
Face contacts, do not have the transmission of power and vibration between disc spring gland and shift fork so that the rotation of main shaft and the tension of trombone slide, unclamp
Action is non-interference, improves the stability of pinching action and the precision of machining.
In above-mentioned hollow electromechanics clamping device, described shift fork one end hinged with stirring ring is semiorbicular connecting portion
One, described in stir there is on ring cylindrical groove, the both sides of described connecting portion one are respectively by holding screw cylinder and stir on ring
