Description
Technical field
The present invention relates to automobile assembling technical field, particularly relate to the fastening special tooling of a kind of driving shaft locking nut.
Background technology
Automotive brake common at present generally comprises brake disc and caliper, the centre of brake disc is driving shaft, driving shaft is fixedly connected with brake through brake center, when assembling, need to be screwed into driving shaft locking nut on the driving shaft, or in brake maintenance process, driving shaft locking nut installs after unloading again also needs again, but when stubborn driving shaft locking nut, driving-disc can rotate together along with driving shaft and cause completing assembling work, thus affects assembly quality.Usually be all the side of brake pressure on the ground now, thus prevent driving shaft from rotating in caliper, then just can carry out driving shaft nut and surely turn round.This kind of method is seriously subject to place restriction, make troubles to the assembling of driver and maintenance, install or overhaul efficiency very low, brake disc and earth surface can cause brake disc periphery to knock damage and cause out-of-flatness etc., obviously this kind of method serious non-compliance Human Engineering theory.
Chinese patent Authorization Notice No.: CN201769041U, authorized announcement date on March 23rd, 2011, disclose a kind of locknut tightening assistant tool for driving shaft of automobile brake, the position-arresting disk that it comprises a handle and is fixedly linked with handle one end, position-arresting disk is provided with locking nut trepanning and bolt position limiting structure, bolt position limiting structure comprises two U-shaped structures, the axis of symmetry of the U-shaped of two U-shaped structures overlaps, and with a diameter conllinear of locking nut trepanning, two U-shaped structures are relatively arranged on the two ends of this diameter.Structure is simply light and handy, operation location efficient quick, and cost easy to manufacture is low, and when effectively can solve fastening driving shaft locking nut on auto production line, the problem of rotation followed by brake.When using this kind of aid, need the handle of this instrument of left-handed, right hand gripping torque wrench is tightened driving shaft locking nut and is surely turned round operation, and driving shaft locking nut needs very large power to lock, and left hand, power on the right hand is active force and reaction force, both hands all can be subject to very large active force, fatigue strength is large, both hands without foundation gripping handle or torque wrench time, the active force that therefore can provide due to the shortage strong point is little, perhaps driving shaft locking nut can be normally tightened time incipient, easily produce tired after time is slightly long and cause tightening driving shaft locking nut, and to turn in process two U-shaped structures with spacing by the boss bolt on brake disc, on the stud of boss bolt radial comprehended cause thread damage.
Summary of the invention
The present invention is in order to overcome driving shaft locking nut tightening assistant tool of the prior art in use, operator easily produces fatigue and affects efficiency of assembling, also can damage the deficiency of boss bolt screw thread simultaneously, provide a kind of easy to use, efficiency of assembling is high, operate more laborsaving, the fastening special tooling of driving shaft locking nut of boss bolt can not be damaged.
To achieve these goals, the present invention adopts following technical scheme:
The fastening special tooling of a kind of driving shaft locking nut, comprise substrate and the baffle plate being located at substrate homonymy two ends, the baffle plate being positioned at substrate two ends is fixed with cylinder respectively, two cylinders are connected with a cylinder controller simultaneously, the output shaft of two cylinders is coaxial and towards the center of substrate, the output shaft of two cylinders is fixed with limited block respectively, the bottom surface of described limited block is plane, the end face of limited block is acclivitous inclined-plane from outer end to link, and the bottom surface of described limited block is provided with friction plate.The head of limited block is wedge shape, the head of two limited blocks is stuck in the two ends place brake block of caliper and the gap of brake disc, friction plate and brake disc, then control two cylinder output shafts by cylinder controller to stretch out simultaneously, make to hold out against with brake block on the upside of the head of limited block, friction plate and brake disc compress fits, so just can prevent brake disc from rotating, then driving shaft locking nut is tightened by spanner, after driving shaft locking nut screwing, the retraction of cylinder output shaft is made by cylinder controller, frock can be taken off, whole process is very convenient, laborsaving, efficiency of assembling is high, frock and boss bolt contactless, boss bolt can not be damaged.
As preferably, the L-shaped structure in cross section of described baffle plate, wherein a lateral surface is connected with baseplate-laminating, and another medial surface is fixedly connected with cylinder.The baffle plate bonding strength of L shape structure is large, after cylinder output shaft stretches out, can bear very large support force.
As preferably, described baffle plate is connected by rotating shaft with between substrate, and described substrate is provided with arcuate socket, and described baffle plate and the joint face of substrate are provided with caging bolt, and the outer end of caging bolt is through arcuate socket and pass through nut check.Two ends due to caliper are not parallel substantially, general angle all and between being 20 ° to 40 °, baffle plate can rotate in certain scope around rotating shaft, therefore can according to the angle of the angle controllable register at caliper two ends, make the head of two limited blocks all vertical with the two ends of caliper, now limited block and brake block contact surface maximum, after cylinder output shaft stretches out, limited block accepts evenly, stable, the pressure result of rubbing surface reaches best, therefore this kind of frock can be applicable to dissimilar brake use, highly versatile.
As preferably, coefficient of friction >=0.42 between described friction plate and brake disc.Coefficient of friction in national standard between brake block and brake disc is between 0.35-0.40, this scope makes brake block namely can not lose efficacy also can not braking with locked wheels dish, the coefficient of friction of friction plate is greater than after 0.40, can ensure to be subject to friction plate braking with locked wheels dish after vertical active force, thus brake disc cannot be rotated, be convenient to tighten driving shaft locking nut.
As preferably, the middle part of substrate is provided with pin-and-hole, is provided with alignment pin in described pin-and-hole.When the active force of two back-up blocks is all vertical with the two ends of caliper, the reaction force that two back-up blocks receive not is an equilibrant force, therefore whole substrate can offset to disc centres, in order to prevent this skew, now alignment pin is inserted in locating hole, the head of alignment pin just in time snaps in in the boss gap on brake disc inside caliper, thus provides an outside active force with making a concerted effort of balancing that two back-up blocks are subject to for whole substrate.
As preferably, the two ends of substrate are overlapped respectively and are had rubber protecting jacket, and described rubber protecting jacket together envelopes baffle plate, cylinder.Rubber protecting jacket is coated to the lower end of baffle plate, cylinder etc., and the lower end of anti-baffle plate or the various edges and corners of cylinder contact with driving-disc and knock the rubbing surface damaging driving-disc.
As preferably, described substrate is provided with handrail with the opposite flank of baffle plate.Handrail is convenient to the installation and removal of whole frock.
Therefore, the present invention has easy to use, and efficiency of assembling is high, operates more laborsaving, can not damage the beneficial effect of boss bolt.
