Embodiment
embodiment
As Figure 1-4, comprise action bars 1, horizon bar 2, connecting rod 3, support bar 4, chuck 5 and position-limited rack 6, the top of action bars connects one end of horizon bar, the other end of horizon bar is connected with one end of connecting rod by rotating shaft 7, the other end of connecting rod connects one end of support bar by rotating shaft, the other end connecting clip of support bar, is provided with the position-limited rack of horizontal direction between described horizon bar and connecting rod, be provided with the position-limited rack of vertical direction between connecting rod and support bar.
Described position-limited rack is made up of arc-shaped limit plate, spacing hole 8 and set screw 9, and on limiting plate, uniform intervals is provided with spacing hole, and set screw is movably arranged on spacing hole, and external diameter and the spacing hole internal diameter of set screw match.
Described action bars comprises multiple single-unit, is flexibly connected between single-unit action bars by screw buckle.
Described chuck is spanner chuck, comprise dynamic chuck 501, quiet chuck 502, chute, storage tank, screw rod 503 and motor 504, quiet chuck is arranged on one end of head, dynamic chuck is arranged in chute, the bottom of dynamic chuck is provided with screw thread, screw rod is arranged in storage tank, and one end of screw rod is connected with motor by connecting rod 508, and screw thread and screw rod match.Described chuck is provided with current/voltage line tie point 509, control circuit module 505 and battery case 506, and the folder face of described quiet chuck is provided with pressure sensor 507.
Also comprise remote controller, the inside of remote controller is provided with reception reflector, and the outside of remote controller is provided with clamp button 10, loose ends button 11, mains switch 12 and spacing warning light 13.
One, be directed to direction transformation problem, this apparatus design two adjustable fixed connection apparatus, are respectively used to the adjustment realizing horizontal plane and vertical plane, by two sides structure adjusting, freely adjust with 360 degree that realize whole equipment.This device adopts rolling bearing to combine with multiple spot position-limited rack, selective with multi-point above position-limited rack, after choosing suitable angle, be fixed on insulating bar by set screw by the some position chosen, solid framework ensure that collet segment can not cause the malfunctioning rear chuck bending of fixed axis cannot the phenomenon of clamp because current/voltage line is overweight.
two,be directed to Insulation Problems, this apparatus design more piece insulating bar connected mode is strengthening insulation distance, ensure operating personnel's operation, but draw new problem thus, lengthening distance, how to realize clamp operation, for this reason, this device introduces remote control device, and operating personnel handles remote controller at Ground Operation, realize chuck deciliter, curve clamp, loose ends process.
Three, clip designs, traditional chuck many employings spring chuck, this chuck not easily combines with motor, and then is difficult to realize remote control process.This device adopts spanner chuck, spanner is utilized to move chuck and screw thread is combined closely, screw propulsion principle, connect at screw thread axis place with small machine, realizing motor drives screw thread to advance dynamic chuck, reach a deciliter object, simultaneously, for preventing operating personnel because of excessively far away apart from clamp point, cause chuck tension motor damage or cross the phenomenons such as loose wiring is bad producing, the ad hoc pressure sensor of this device is in quiet chuck folder face, by detecting chuck dynamics, be converted into phase induced current, the prior setting threshold of comparison, automatic identification judges whether overtravel, when reaching tightness, motor automatic stop rotates the concurrent number of delivering letters, remote controller red light lights.
Four, the universal clamping pliers whole structure of distance type, wherein action bars comprises multiple single-unit, is flexibly connected between single-unit action bars by screw buckle, can arbitrarily increase by tested device height or reduce action bars quantity.
Operating process needs two people to complete, a people helps the insulating bar being with universal clamping pliers, another people's operating and remote controlling equipment, send deciliter instruction, after device receives, control motor positive and inverse and realize dynamic chuck deciliter, pressure is converted into current value by transducer simultaneously, comparison threshold value, if real-time current value exceedes threshold value, then motor stops working on, and alarm song admittedly of feeling nervous, remote controller blinking red lamp simultaneously, alert chuck is fastening can be tested, superthreshold as non-in real-time current, then motor works on, until reach threshold value, motor quits work concurrent fastening alarm song.
