Abstract
The utility model discloses a square drive hydraulic torque wrench with a buckling claw. The square drive hydraulic torque wrench with the buckling claw is characterized by comprising a base, wherein a shell is installed on the base, an oil cylinder and a force transmission plate are installed in the shell, the piston rod stretching-out end of the oil cylinder is connected with the force transmission plate, a drive shaft is installed in the force transmission plate, a slant counter-force arm is arranged between the base behind the oil cylinder and the upper portion of the shell, 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, the 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 square drive hydraulic torque wrench with the buckling claw is reasonable in structural design, compact, high in strength and integrated in design, and guarantees that the operating radius is small; the counter-force arm provides multiple position supports to protect a reaction object against damage; the overall structure enables torque to be output constantly, so that high accuracy is provided for the whole twisting process of the wrench, wherein the accuracy can reach +/-3%.
Description
Technical field
The utility model relates to a kind of spanner structure, and hydraulic torque wrench drives in the side that relates in particular to a kind of bracelet pawl.
Background technology
Torque wrench of the prior art is simple in structure, take up room large, make total Heavy Weight, its type of drive is to drive ratchet to rotate by the end-tooth on force transmitting board, thereby realizes drive shaft, and its difficulty of processing is high, technological process is complicated, 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, provides a kind of side of bracelet pawl to drive hydraulic torque wrench.
The utility model is achieved through the following technical solutions:
Hydraulic torque wrench drives in a kind of side of bracelet pawl, it is characterized in that: include base, on described base, housing is installed, oil cylinder and force transmitting board are installed in described housing, the piston rod external part of described oil cylinder is connected with force transmitting board, in described force transmitting board, driving shaft is installed, between the base at described oil cylinder rear and upper shell, 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 force transmitting board rotates, and ratchet mechanism in force transmitting board 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 reasonable in design, compactness, high strength, Integral design, guarantee that operative radius is less, counter-force arm provides a plurality of positions to support, and protects reaction thing and is not destroyed, overall structure makes moment of torsion constant output, for the whole twist process of spanner provides higher precision, reaches ± 3 ﹪.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, hydraulic torque wrench drives in a kind of side of bracelet pawl, include base 1, housing 2 is installed on base 1, oil cylinder 3 and force transmitting board 4 are installed in housing 2, the piston rod external part of oil cylinder 3 is connected with force transmitting board 4, driving shaft 5 is installed in force transmitting board 4, between the base 1 at oil cylinder 3 rears and upper shell 2, be provided with the counter-force arm 6 of inclination, the rear end cap middle part of oil cylinder 3 is provided with draw-in groove 7, the bottom of draw-in groove 7 is installed with button pawl fixed head 8, the hinged button pawl 9 that is provided with on button pawl fixed head 8, the upper end of button pawl 9 and draw-in groove 7 fasten, lower end is arranged in counter-force arm 6, and be provided with extension spring 10 between bottom and button pawl fixed head 8.
