Abstract
The utility model relates to a manual preset torque spanner. The utility model is composed of a spanner head, a pendulum rod, a force applying sleeve, a torque driving device in the force applying sleeve, an alarm mechanism and a torque presetting mechanism. The torque driving device has the structure that the tail end of the pendulum rod is hinged with the front end of a knocking lever by a connecting pin, and the knocking lever passes through a slide block in the force applying sleeve and is hinged with the slide block. The rear end of the knocking lever is hinged with the connecting rod, the other end of the connecting rod is hinged with an eccentric slide block, and the other end of the eccentric slide block is connected with the torque presetting mechanism. The utility model has the advantages of light weight, accurate and reliable indicating values, small processing difficulty, etc.
Description
The utility model belongs to the hand-operated tools class, but a kind of spanner of preset torque particularly.
In existing homemade torque wrench, mostly the product produced a few years ago of structure and Britain is close, this spanner by torque drive mechanism that adorns in driving end, wrenching bar, afterburning sleeve, the sleeve and moment of torsion preset mechanism, alarm mechanism forms.In Chinese patent, the patent No.: ZL97208330.8, name are called the comparatively advanced of " torque wrench ", its torque drive realizes by the two-stage slider-rocker mechanism, its structure is, in sleeve, be provided with a guide pin bushing that slides, other parts of two-stage slider-rocker mechanism all place in the guide pin bushing of slip, and its annexation this paper is not described herein.This utility model have calibration accurately, give and put advantages such as quick.But, make that the weight of spanner is bigger than normal and increased manufacture difficulty because sliding guide sleeve is long.
The purpose of this utility model provides a kind of superior performance, stable, and structure is simpler, and weight is little, a kind of new presetting system torque wrench that cost is low.
The technical solution of the utility model is: driving end 1 is inserted in the end hole of fork 3, and connects with pin 2, and fork 3 is outer to be equipped with afterburning sleeve 5, connects by neck pin 4, torque drive mechanism, alarm mechanism, moment of torsion is housed in the afterburning sleeve 5 successively presets mechanism.The utility model mainly improves torque drive mechanism, saved sliding guide sleeve, its structure is, tail end at fork 3, by connecting pin 6 with knock lever 7 front ends and be hinged, knock lever 7 and be passed in the slide block 8 that slides in the afterburning sleeve 5, knocking lever 7 also is hinged by bearing pin 9 with slide block 8, the rear end of knocking lever 7 is by riveting axle 11 connecting rod 12 that is being hinged, the other end of connecting rod 12 is hinged by the eccentric shoe 15 of bearing pin 13 with band roller 14, and the rear end of slide block 15 is connecting moment of torsion and presetting mechanism's 16 (see figure 1)s.
Be provided with beating point C in the rear end lower of knocking lever 7, when spanner institute application of force square reached preset torque, knocking lever 7 will clockwise rotate around bearing pin 9, and beating point C will strike the inwall of afterburning sleeve 5, sends the sound of alarm.
Also be rotary with a screw 10 on the lever 7 knocking, regulate its overhang by the through hole B on the afterburning sleeve 5, and then,, play the purpose of revising the error of indication in order to the output valve of fine setting moment of torsion by knocking lever 7, riveting axle 11 change connecting rods 12 and afterburning sleeve 5 axis (being axial force) angle.
The structure of slide block 8 is to be made of two smaller part nahlocks that are contained in the afterburning sleeve 5, between two smaller part nahlocks groove is arranged, knock lever 7 and pass groove, and by bearing pin 9 hinged (see figure 2)s.
Driving end 1 can be a ratchet head, also can be opening head or wabbler.
The utility model is simple in structure, compactness, and frictional force is little between member, and indicating value is accurately, reliably.Simultaneously, because no guide pin bushing structure, thereby alleviated weight, reduced difficulty of processing.
The drawing explanation:
Fig. 1 is the utility model structural representation
Fig. 2 is the A-A profile of Fig. 1
The utility model is described in further detail below by embodiment.
The driving end 1 that will contain ratchet is inserted in the end hole of fork 3, and connect with pin 2, afterburning sleeve 5 is housed outside the fork 3, connect by neck pin 4, tail end at fork 3, by connecting pin 6 with knock lever 7 front ends and be hinged, knock lever 7 and be passed in the slide block 8 that slides in the afterburning sleeve 5, the structure of slide block 8 is to be made of two smaller part nahlocks that are contained in the afterburning sleeve 5, spacing shape groove between two slide blocks, knock the groove that lever 7 passes 8 of slide blocks, and it is hinged by bearing pin 9, the rear end of knocking lever 7 is by riveting axle 11 connecting rod 12 that is being hinged, and the other end of connecting rod 12 is hinged by the eccentric shoe 15 of bearing pin 13 with band roller 14, and the rear end of slide block 15 is connecting moment of torsion and presetting mechanism 16.Be provided with beating point C in the rear end lower of knocking lever 7, also be rotary with a screw 10 on the lever 7 knocking, can regulate its overhang by the through hole B on the afterburning sleeve 5, and then by knocking lever 7, riveting axle 11 change connecting rods 12 and afterburning sleeve 5 axis (being axial force) angle, in order to the output valve of fine setting moment of torsion, play the purpose of revising the error of indication.
