The specific embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.Should be noted that the embodiments described herein only is used to illustrate, be not limited to the utility model.
As shown in Figure 1, multifunctional pliers of the present utility model comprises left caliper 2 and right caliper body 3.Left caliper 2 and right caliper body 3 are linked together by hinge axis 1 cross-articulation.
Multifunctional pliers of the present utility model, handle 21 and right handles 31 ends are respectively equipped with the Bolt dismantling device leftward.
The Bolt dismantling device of left handle 21 ends comprises that the base 211 that is shaped in left handle 21 end faces and 212, two latches 212 of two latches are arranged on the base 211 and with respect to the center line symmetry of left handle 21.During use, the jack rotation left handle 21 that two latches 212 are aligned on the workpiece gets final product.When being used for dismounting and having the securing member of central, circular endoporus, can also between two latches 212 on the base 211, be provided with boss 213 with base 211 one.The height of boss 213 can a little higher than latch 212 height, 2-5mm for example is with the convenient position that aligns each hole in disassembly process fast.
The Bolt dismantling device of left handle 21 ends also can removably be connected left handle 21 ends, and the Bolt dismantling device also is not limited to above-mentioned concrete structure, can design concrete structure as required arbitrarily or change the structure that needs arbitrarily, convenient, quick when the screw nut of dismounting different types of structure like this.
The Bolt dismantling device of right handles 31 ends is and right handles 31 integrated action bars 34, and this action bars 34 can be solid, and cross section is triangular in shape, square, regular pentagon or regular hexagon, is used for corner bolt in the dismounting; Action bars 34 also can be to have center through hole, and the cross section of center through hole is triangular in shape, square, regular pentagon or regular hexagon hole, is used for the common outer corner bolt of dismounting.
Be provided with near hinge axis 1 position on the left handle 21 and prevent that right handles 31 from rotating and surpass 90 ° left limit platform 25, the center line of the center line of this left limit platform 25 and left handle 21 is into about 90 ° angle.Be provided with near hinge axis 1 position on the right handles 31 and prevent that left handle 21 from rotating and surpass 90 ° right limit platform 35, the center line of the center line of this right limit platform 35 and right handles 31 is into about 90 ° angle.Certainly, the relative rotation angle between left handle 21 and the right handles 31 is not limited to 90 °, and it all is feasible being no more than 120 °.
As shown in Figure 2, workpiece to be removed is two inner sleeve 10 and the outer tubes 20 that are sleeved on together, in order to reinforce the bonding strength between inner sleeve 10 and the outer tube 20, pin 30 has been installed between inside and outside sleeve pipe.When using multifunctional pliers of the present utility model to dismantle pin on this workpiece, the operator holds outer tube 20 with a handgrip, the left and right jaw of multifunctional pliers is opened and be clamped on the outer tube 20 with the another hand, and after making thimble 4 alignment pins 30, the left and right handle of grip pressure firmly, thereby pin 30 is ejected by thimble 4, and stretch out by slotted hole 5, at this moment can directly pin 30 be taken out from internal and external casing with hand, perhaps pin 30 is pulled out from internal and external casing, thereby two inside and outside sleeve pipes that are sleeved on are together separated with the clamping section of multifunctional pliers.Otherwise, when assembling, will connect the pilot hole that pin inserts workpiece in advance earlier, use thimble 4 alignment pins 30 grip pressure left and right sides handles again, thereby pin 30 is seated.Therefore, when using the pin on this tubular workpiece of multifunctional pliers dismounting of the present utility model, only can finish by an operator, very convenient, quick.
For the fastening bolt 40 of as shown in Figure 3 aircraft special use, the central authorities of the nuts 41 of this fastening bolt 40 have circular inner hole 411 and two pin-and-holes 412.Can use the Bolt dismantling device of the left handle end of multifunctional pliers of the present utility model to dismantle, boss 213 is inserted in the endoporus 411 of bolt 40, two latches 212 are inserted into respectively in two pin-and-holes 412, rotating left handle 21 then is dismantled and assembled this fastening bolt 40 again.Before rotating left handle 21, can also open right handles 31, just make right handles 31 turn over 90 ° with respect to left handle 21 around hinge axis 1, can grip right handles 31 this moment rotates left handle 21, in fact increased the length of the arm of force, under the identical situation of moment, arm of force lengthening makes operation more laborsaving.
For interior corner bolt 50 as shown in Figure 4, can use the Bolt dismantling device of the right handles end of multifunctional pliers of the present utility model to dismantle, rotate right handles 31 in the endoporus 511 of the nut 51 of corner bolt 50 in the bottom of action bars 34 is inserted into and get final product.For laborsaving, can make left handle 21 turn over 90 ° and grip right handles 31 rotation left handles 21 again with respect to right handles 31.
There is a large amount of suit pipe fittings as shown in Figure 2 on the aircraft, and fastening bolt as shown in Figure 3, Figure 4.The utility model is at the custom-designed multifunctional pliers in aircraft maintenance field, the reasonable distribution and the polyfunctional best of breed that meet mechanics, the operator only needs the instrument can the structural multiple connector of fastening very like a cork or loosening aircraft system, is specially adapted to the dismounting of pin on the relevant special tubular workpiece.
Use multifunctional pliers of the present utility model, can reduce the number of times of repair and replacement instrument to greatest extent, and need not two people or the dismounting of many people cooperation, can reduce work difficulty and labour intensity significantly, save the operating time, operating efficiency can improve more than 30 times.
Though described the utility model with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.The spirit or the essence that do not break away from utility model because the utility model can specifically be implemented in a variety of forms, so be to be understood that, the foregoing description is not limited to any aforesaid details, and should be in the spirit and scope that claim limited of enclosing explain widely, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
