Description
Technical field
The utility model relates to a kind of nut screwing clamping device, specifically is a kind of automatic screwing device of automobile absorber pillar assembly nut.
Background technology
Automobile absorber pillar assembly is made up of damper, steering bearing, damping spring, beam, stop nut etc.When the mounting column assembly, need stop nut be screwed on the screw rod at last, its moment requires high, and installation quality is very important to the safety of car.But because damper body is the cylinder thin-wall steel tube, inner screw rod drives piston and can move up and down, and also can rotate relative to steel pipe.There is fixture the steel pipe outside, and when fastening nut, the cylinder steel pipe can not rotate, but stop nut rotates with screw rod, and nut can't reach the prescribed torque value.Therefore adopt manual manipulation method that a back-up wrench is stuck on the interior connecting screw rod of shock absorber strut assembly usually, prevent its rotation, with torque spanner stop nut is screwed to the regulation moment values then.The method complicated operation, workload is big, and is difficult to reach productive temp.
Summary of the invention
The goal of the invention of the utility model be to overcome the above-mentioned deficiency of prior art and provide a kind of easy to operate, tighten reliable, save the labour, effectively promote the automatic nut screwing clamping device of productive temp.
The technical scheme of the utility model is: tubular flat key sliding cavity is loaded on casing top; Flat key sliding cavity inwall is provided with the dive key that can slide up and down along the flat key sliding cavity; Flat key sliding cavity upper end is provided with the spring end cap; The spring end cap is fixed in the spring upper end that is used to push down the screw rod fixed axis; Screw rod fixed axis top places in the flat key sliding cavity, through the dive key limit rotation; Screw rod fixed axis middle part places in the casing, and stretch out outside the casing bottom; Screw rod fixed axis bottom is provided with and is used to block the flat groove of the flat-shaped termination of screw rod to be processed to prevent that screw rod to be processed from rotating; Be used for tightening outside the screw rod fixed axis of gear sleeve in bearing holder (housing, cover) is loaded on casing of fastening nut; Tightening the gear sleeve bottom is and the step-like structure of treating that fastening nut cooperates; Tightening gear sleeve is in transmission connection through travelling gear and driven wheel sleeve; The power transmission shaft front end that is used to drive the rotation of driven wheel sleeve is loaded in the driven wheel sleeve.
The said gear sleeve of tightening is in bearing is loaded on casing.
Said travelling gear is in bearing is loaded on casing.
Said driven wheel sleeve is in bearing is loaded on casing.
Said power transmission shaft is the power transmission shaft of air pressure gun; Said air pressure gun is fixed in casing through air pressure gun standing screw and air pressure gun fixed connecting plate.
Said casing comprises upper box, lower box.
The utility model adopts adjustable force moment formula system air pressure gun as power, through the gear train carry-over moment to tightening gear sleeve.In last lower box, deep groove ball bearing is housed respectively is used for the Support Gear quill, last lower box is screwed and is integral.Air pressure gun and upper box are connected as a single entity through bolt and steel plate, and the air pressure gun top is held with balance crane, up and down convenience.In order to prevent that the damper screw rod from following stop nut and rotating together, the screw rod fixed axis can move up and down but the bar that can't rotate, and the lower end has flat groove, with the flat-shaped termination on the top of blocking the damper screw rod, screw rod is fixed.Because screw position is motionless, in nut screwing clamping decline process, the screw rod fixed axis moves upward in the flat key sliding cavity along with the decline of the utility model integral position.This moment, the spring compression of screw rod fixed axis upper end made the screw rod fixed axis tightly block the flat-shaped termination of screw rod, and the gear sleeve of tightening that the screw rod fixed axis is peripheral continues rotation, accomplishes the nut screwing clamping action.
The utility model has fixedly damper screw rod and the function of fastening nut automatically concurrently, and is simple to operate during use, earlier nut manually is placed on the damper screw rod; The screw rod fixed axis is blocked the flat-shaped termination of damper screw rod, the utility model is whole then descends again, after tightening gear sleeve and touching nut; One key control starts air pressure gun, tightens gear sleeve and begins to rotate with nut screwing clamping on the damper screw rod, reach the regulation moment values after; The air pressure gun power that breaks automatically, work is accomplished.Whole process operator only needs the light the utility model of pressing downwards, and the utility model is moved downward with nut, has saved the working time, makes productive temp improve 5 times at least, and laborsaving, has reduced labor strength.

The specific embodiment
Among Fig. 1, the utility model mainly comprises the two large divisions: first is a damper screw rod standing part, and second portion is the nut screwing clamping part.
Damper screw rod standing part mainly is made up of flat key sliding cavity 11, spring end cap 12, spring 13, screw 14, dive key 15, screw rod fixed axis 24 etc.Round end dive key 15 is up and down in flat key sliding cavity 11, and screw rod fixed axis 24 can't left-right rotation under the obstruction of dive key 15, and under the guide effect of dive key 15, can slide up and down.Spring 13 is pressed in and makes fixed axis 24 receive elastic force on the end cap 12, is pressed in damper screw rod 38 tops, makes the flat groove of fixed axis 24 can block the flat-shaped termination 37 of damper screw rod, prevents that screw rod from rotating.
Nut screwing clamping part mainly by upper box 1, bearing, lower box 18, driven wheel sleeve 4, travelling gear 8, tighten gear sleeve 10 and form.The power source that is adopted is system's air pressure gun that common band torque adjusting in market and moment show.The front end of air pressure gun power transmission shaft is a square head; Insert in the hole, four directions, upper end of driven wheel sleeve 4, driven wheel sleeve 4 drives travelling gear 8, and travelling gear 8 drives tightens gear sleeve 10; Tighten gear sleeve 10 and tighten the nut on the damper screw rod, make it reach the moment values of regulation.When fastening nut, to tighten gear sleeve 10 and do descending motion with the relative screw rod of nut, screw rod fixed axis 24 receives the reaction force of screw tip and in sliding cavity 11, does ascending motion.Therefore whole nut screwing clamping process is that the action that fixed axis 24 blocks screw head and fastening nut is accomplished simultaneously.Tighten the action finish after, take off the utility model, spring reset makes fixed axis 24 return to initial position, waits for next workpiece.
Power set are mainly by balance crane 30, suspension ring 31, air pressure gun 32, air pressure gun standing screw 33, operating grip 34, and air pressure gun fixed connecting plate 35 is formed.Air pressure gun 32 is fixed in casing through air pressure gun standing screw 33 and air pressure gun fixed connecting plate 35, keeps the utility model body vertical direction stress balance through balance crane 30 again.Control button on operator's control operation handle 34 rotates air pressure gun 32, and air pressure gun 32 reaches automatic disconnection source of the gas after the moment values of setting.Balance crane 30 carries the whole weight of the utility model, and is light when making operation.
The 2nd, bearing, the 3rd, sealing ring, the 5th, the clutch shaft bearing end cap, 6 is second bearing (ball) covers; The 7th, bearing, the 9th, bearing, the 16th, last sealing gasket, the 17th, outage soket head cap screw; The 19th, the lower seal pad, 20 is the 3rd bearing (ball) covers, and 21 is the 4th bearing (ball) covers, and 22 is the 5th bearing (ball) covers; The 23rd, (powder metallurgy) bearing, the 25th, sealing ring, the 26th, lubricating cup.
Among Fig. 2, the 27th, cross sunk screw, the 28th, interior hexagonal cylinder screw, the 29th, interior hexagonal cylinder screw.
Among Fig. 3, Fig. 4, the 24th, the screw rod fixed axis.
