Description
Technical field
The present invention relates to a kind of spanner, relate in particular to a kind of adjustable type torque spanner.
Background technology
In machinery industry, being threaded is the most general connected mode, the overwhelming majority must tighten, before making to be connected to and bearing service load, be subject in advance the effect of power, therefore, spanner is an important instrument, be widely used for many years, there is the spanner of determining moment function and also in some occasions, used.Yet the torque wrench function of using is at present all more single, and cannot preset peak torque.Also the torque spanner occurring in prior art awaits further improving.
As Chinese patent discloses CN 202037580 U, a kind of torque spanner of adjustable moment size is disclosed, can realize the torque spanner of Torque-adjusting size.It comprises main body and driving end, is flexibly connected, and in main body, is equipped with along body shaft to activity for the axial positioning mechanism of torque adjusting between its main body and driving end, and this axial positioning mechanism is by being slidably connected between steel ball and driving end.
But above-mentioned torque spanner adopts single steel ball brake braking force less, its handle part is emptied in long-term use procedure and is very easily occurred that distortion causes spanner to be scrapped simultaneously, and stability is also poor.
Summary of the invention
In order to solve, existing torque spanner preset force is little, handle is yielding, the shortcoming of less stable, the invention provides a kind of adjustable type torque spanner.
The technical solution adopted for the present invention to solve the technical problems is: described adjustable type torque spanner, comprise handle, driving end, described driving end is connected with handle end, driving end is provided with and regulates chamber, regulate in chamber and be provided with brake disc, brake disc one end is provided with the through hole being communicated with driving end surface, in spanner installing hole, be combined with dismountable spanner, the other end of brake disc is combined with adjustable cap, described brake disc is ratchet, the tooth surface of ratchet is the arc surface seamlessly transitting, regulate side, chamber to be provided with screw thread, the threaded engagement of screw thread and adjustable cap outer rim, adjustable cap is provided with circular pit with the one end that regulates chamber to coordinate, pit side is inclined-plane, pit centres is provided with axis hole, adjustable cap outer surface is provided with adjusting boss, regulate bottom, chamber to be provided with boss, boss top has been evenly arranged pilot hole, pilot hole axis extends along boss axis direction, in pilot hole, be provided with spring, spring is pressed with detent ball near brake disc one end, spring is provided with adjusting ball near adjustable cap one end, boss center is provided with through hole and coordinates with clamping head one end, one end that brake disc coordinates with adjustable cap is provided with rotating shaft, shaft hole matching on rotating shaft and adjustable cap, the end face that driving end is combined with adjustable cap is provided with along the graduation mark that regulates cavity edge to distribute.
Further, in described through hole, be provided with axle sleeve.
Further, described adjustable cap top is provided with adjusting boss.
The invention has the beneficial effects as follows: adopt adjustable cap to regulate the convenient use of preset force at Wrench head, the less precision of governor motion is convenient to guarantee, adopts simultaneously and regulates the even bearing torque of ball to prevent that the governor motion distortion while preset torque power upper limit from improving.
