The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
Such as Fig. 1, shown in Figure 2, the manual torque wrench of a kind of double-edged sword type high pulling torque, comprise handle jacket 35, be arranged at the handle locking mechanism in the handle jacket 35, be connected in the moment of torsion scale mechanism of handle jacket 35 front ends, be arranged at the moment of torsion output bindiny mechanism of moment of torsion scale mechanism front end, be arranged at the second lever 13 in the moment of torsion output bindiny mechanism, be arranged at and preset spring 2 between handle locking mechanism and the second lever 13, be connected in the driving head 39 that moment of torsion is exported the tube connector 19 of bindiny mechanism's front end and is connected in tube connector 19 front ends, the chrome-molybdenum steel structure that driving head 39 forms for machined is provided with square mortise on the driving head 39.
Driving head 39 of the present invention adopts the steel alloy manufacturing, when weight is light and handy, has guaranteed the bearing strength of 1500N.m high pulling torque.Be different from other stamping forming processing technologys of recessed square toes of the same type, driving head 39 of the present invention adopts mach mode to process, and has guaranteed and the compatibility of other various brands, all kinds of plug-in units and the reliability of moment of torsion transmission.The head of the present invention dissimilar plug-in unit of can arranging in pairs or groups is similar to the use of fork spanner, uses comparatively extensive.
Moment of torsion output bindiny mechanism comprises that rear-echelon support piece 15, the place ahead support piece 20 and be hinged on rear-echelon support piece 15 by pivot pin 17 and pin-and-hole to support two square links 18 between the piece 20, the rearward end of rear-echelon support piece 15 to be connected with moment of torsion scale mechanism with the place ahead, and the leading section of the place ahead support piece 20 is connected with the rearward end of tube connector 19.The outside of two square links 18 also is provided with two saddle type shells 36.
The point contact of the uniqueness of stressed fulcrum second lever connector 26 and the connection design of square link 18, be the output of the required moment of torsion of bolt and nut with applied force transmission on the handle, no matter how the length of torque wrench changes (being how point of application position changes), output torque all can not change, greatly reduce operator's instructions for use, this is that other mechanical torque spanner requirement point of applications are that handle center is unexistent, saddle type shell 36 usefulness screws are fixed, and prevent that dust, foreign material etc. from entering this mechanism.The design of the releasing structure of second lever 13 is comparatively reasonable, when torque value during greater than the thrust of spring, and this relieving mechanism action, the sound prompting of output " click is rattled away ".
Moment of torsion scale mechanism comprises scale mechanical cap 27, be arranged at the scale value photoscope 24 on the scale window of scale mechanical cap 27 and be arranged at scale swing pinion 29 and stationary gear 28 in the scale mechanical cap 27.This moment of torsion scale mechanism can make the user check easily set torque value.
An installing sleeve 16 is arranged in handle jacket 35, the moment of torsion scale mechanism rear-echelon support piece 15, and handle locking mechanism is arranged at the inside of the latter half of installing sleeve 16, presets the inside that spring 2 is arranged at the first half of installing sleeve 16.Handle locking mechanism comprises that stock 14 reaches thrust washer 38, locking nut 31, handle locking spring 1, locking sleeve 32, the first jump ring 7, handle lock ring 23, locking pin 22, drive collar 33, drive 25 and the locking button 34 on the latter half that is set in turn in from front to back this stock 14, be provided with the second jump ring 8 between locking button 34 and the handle jacket 35, preset the rear sleeve of spring 2 and be located on the first half of stock 14.
By profile of tooth separately, engagement unclamps or locks handle.When unclamping, user's rotatable handgrip, thus carry out the setting of required torque value; During locking, guaranteed that handle can not rotate in the use procedure, thereby guaranteed the accurate of moment of torsion output.
Using method of the present invention is very simple.During work, in the square mortise of the protruding square toes partial insertion torque wrench of plug-in unit (package types can be selected according to user's request) that first will be corresponding with bolt and nut and fix in position (the corresponding torque wrench aperture of bullet pin position), rotational lock button 34 is with release handle, rotary handle, show according to the scale on the scale swing pinion 29, the user can require to arrange according to station the torque value of torque wrench, after setting, rotational lock button 34 is with set lever, handle rotates when preventing from using, plug-in unit with driving head 39 is enclosed within on the bolt and nut afterwards, confirm to connect reliable after, beginning manually applies power, until torque wrench is when hearing " click is rattled away " sound, stop immediately the application of force, namely finished the locking operation of bolt and nut.
In addition, also comprise spring 3, the first needle roller 5, rivet pin 9, half column cap 11, stainless steel screw 12, sealing column 21 and dashpot piston 30 among Fig. 2.
Should be noted that at last; above content is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; the simple modification that those of ordinary skill in the art carries out technical scheme of the present invention or be equal to replacement does not all break away from essence and the scope of technical solution of the present invention.
