Abstract
The utility model discloses a hydraulic torque wrench with a locking claw. The hydraulic torque wrench with the locking claw comprises a base, wherein a connector seat is installed on the base, an oil cylinder and a force transmission plate are installed in the connector seat, the piston rod stretching-out end of the oil cylinder is connected with the force transmission plate, a drive shaft is installed at the lower end of the connector seat through a ratchet wheel, the ratchet wheel is in transmission fit with a ratchet below the force transmission plate, a check pawl matched with the inner side of the ratchet wheel is further installed on the connector seat, a spring is arranged between the check pawl and the connector seat below the check pawl, a spring is arranged between the force transmission plate and the connector seat below the force transmission plate, a slant counter-force arm is arranged between the base behind the oil cylinder and an upper cylinder body, a clamping groove is formed in the middle of a rear end cover of the oil cylinder, a buckling claw fixing plate is fixedly installed at the lower end of the clamping groove, a buckling claw is hinged to the buckling claw fixing plate, the upper end of the buckling claw is buckled with the clamping groove, the lower end of the buckling claw is installed on the counter-force arm, and a tension spring is arranged between the lower end of the buckling claw and the buckling claw fixing plate. The hydraulic torque wrench with the locking claw is compact, light in weight and large in torque, and guarantees that the operation radius is small; the accurate check pawl overcomes reversion of the wrench and improves pre-tightening accuracy.
Description
Technical field
The utility model relates to a kind of spanner structure, relates in particular to a kind of hydraulic torque wrench with lock pawl.
Background technology
In prior art, the type of drive of torque wrench is to drive ratchet to rotate by the end-tooth on force transmitting board, thereby realize drive shaft, in journey, spanner there will be reverse situation, thereby affected normal use, pretension precision is low, and counter-force arm is fixing simple, during use, be easily subject to active force and destroy, affect its service life.
Utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of hydraulic torque wrench with lock pawl is provided.
The utility model is achieved through the following technical solutions:
A kind of hydraulic torque wrench with lock pawl, it is characterized in that: include base, on described base, plinth is installed, oil cylinder and force transmitting board are installed in described plinth, the piston rod external part of described oil cylinder is connected with force transmitting board, the bottom of described plinth is provided with driving shaft by ratchet, described ratchet coordinates with the ratchet transmission of force transmitting board below, the check pawl coordinating with ratchet inner side is also installed on described plinth, between the plinth of described check pawl and force transmitting board and its below, be provided with spring, between the base at described oil cylinder rear and upper cylinder body, be provided with the counter-force arm of inclination, the rear end cap middle part of described oil cylinder is provided with draw-in groove, the bottom of draw-in groove is installed with button pawl fixed head, the hinged button pawl that is provided with on described button pawl fixed head, the upper end of described button pawl and draw-in groove fasten, lower end is arranged in counter-force arm, and be provided with extension spring between bottom and button pawl fixed head.
Its principle is: by high-pressure hose, connect power source (electric hydraulic station), by power source, to hydraulic spanner input high pressure liquid force feed, promote piston back-and-forth movement.Piston driving ratchet rotates, and ratchet promotion ratchet mechanism moves thereupon, moving thereby drive side turns, and realizes pretension and the dismounting of bolt.Structural design by button pawl, is buckled in rear end of the cylinder block by counter-force arm and covers, supplemental support, reaction force that can be certain.
The utility model has the advantages that:
The utility model is compact, lightweight, moment of torsion is large, guarantees that operative radius is less, accurate check pawl device; overcome spanner and reverse, improve pretension precision, provide a plurality of positions to support; protection counter-force arm is not destroyed, for most tools for bolts ' pretension and dismounting occasion, maximum working pressure (MWP) 70MPa.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, a kind of hydraulic torque wrench with lock pawl, include base 1, plinth 2 is installed on base 1, oil cylinder 3 and force transmitting board 4 are installed in plinth 2, the piston rod external part of oil cylinder 3 is connected with force transmitting board 4, the bottom of plinth 2 is provided with driving shaft 5 by ratchet 6, ratchet 6 coordinates with the ratchet transmission of force transmitting board 4 belows, the check pawl 7 coordinating with ratchet 6 inner sides is also installed on plinth 2, between the plinth 2 of check pawl 7 and force transmitting board 4 and its below, be provided with spring 8, between the base at oil cylinder 3 rears and upper cylinder body, be provided with the counter-force arm 9 of inclination, the rear end cap middle part of oil cylinder 3 is provided with draw-in groove, the bottom of draw-in groove is installed with button pawl fixed head 10, the hinged button pawl 11 that is provided with on button pawl fixed head 10, upper end and the draw-in groove of button pawl 11 fasten, lower end is arranged in counter-force arm 9, and be provided with extension spring 12 between bottom and button pawl fixed head 10.
