Description
Technical field
The invention belongs to mechanical manufacturing field, relate to a kind of torque wrench bindiny mechanism specifically.
Background technology
Hydraulic torque wrench has drive-type hydraulic torque wrench and the large series of hollow type hydraulic torque wrench two.As its name suggests, drive-type hydraulic torque wrench drives dimension sleeve to realize the pretension of nut by driving shaft, the benefit that drive-type hydraulic torque wrench compares hollow type hydraulic torque wrench is, as long as when torque range allows, the bolt of different size can be completed according to the corresponding high strength sleeve of replacement, for universal hydraulic spanner, the scope of application is wider.Hollow type hydraulic torque wrench is then be equipped with spacer shell to use, this is also the use specification limiting hollow hydraulic torque spanner, can only bolt specification within its contrast range, this hydraulic torque wrench could be used to realize operating mode, this is also that hollow hydraulic torque spanner becomes a special hydraulic torque wrench, because the operating mode that it uses, be generally screw rod stretch long, spatial dimension is smaller, double nut, pitch of bolts are too little, nut and appts wall too little, or the difficult operating mode of some specific industries is more.
Hydraulic torque wrench is made up of working head, electric hydraulic pump, duplex high-pressure oil pipe, high strength sleeve.By duplex high-pressure oil pipe, power source is transferred to hydraulic torque wrench by electric hydraulic pump, should be produce pressure in inside by electric motor after electric hydaulic pump startup more specifically, the hydraulic oil of inside is passed through oil pipe medium transfer to hydraulic torque wrench, then promote the piston rod of hydraulic torque wrench, make ratchet that driving shaft can be driven to complete the pretension work of bolt by the ratchet of piston rod band wrench front portion.About the auxiliary products of hydraulic torque wrench, electric hydraulic pump has: solenoid-driven (electronic) or compressed air-driven (pneumatic).
The working head of hydraulic torque wrench forms primarily of three parts, body (being also housing), oil cylinder and drive disk assembly.Oil cylinder power output, cylinder piston rod and running part component movement pair, oil cylinder center is that hydraulic spanner amplifies the arm of force to drive disk assembly centre distance, and oil cylinder is exerted oneself and is multiplied by the arm of force, is exactly the theoretical output torque of hydraulic spanner.
At present, the arm of force of hydraulic torque wrench installing sleeve and ratchet all adopts bolt and nut to connect with being connected between hydraulic cylinder piston rod, and need pull down by nut with spanner when changing the arm of force, change inconvenient, speed is slow, affects pretension operating efficiency.
Summary of the invention
For above-mentioned Shortcomings, the invention provides a kind of torque wrench bindiny mechanism:
A kind of torque wrench bindiny mechanism, is comprised escapement and piston rod, is connected between described escapement with described piston rod by rotational coupling mechanism.
Described rotational coupling mechanism comprises connecting plate, pin one, pin two, pin three and spring, wherein, described pin one and pin three are individually fixed in one end of escapement, and described pin two and spring are individually fixed in one end of hydraulic cylinder piston rod, and the other end of spring is connected with the pin three being fixed on escapement one end, one end of described connecting plate does not have circular hole, circular hole is connected with the pin two being located at piston rod one end, and the other end is provided with hook, and hook is connected with the pin one being fixed on escapement one end.
Described pin one, pin two and pin three include cylinder part and threaded joints, and on described escapement and hydraulic cylinder piston rod, corresponding described threaded joints is provided with internal thread hole.
