The invention relates to a counting mechanism of a hydraulic tightening machine. The counting mechanism comprises a counting mechanism body, a piston seal, a drive piston, a spring mechanism, a spring gland, a counter, a piston limiting pin, a body lower cover, a body seal and a locking bolt. The counting mechanism of the hydraulic tightening machine successfully solves the problem that the number of actual using times of a hydraulic tightening machine can not be currently tracked or recorded all the time worldwide. When the service life of easily-worn mechanical components of the hydraulic tightening machine provided with the counting mechanism reaches the limit but the easily-worn mechanical components are not damaged, the easily-worn mechanical components can be replaced in advance, and the phenomenon that the easily-worn mechanical components of the hydraulic tightening machine crack suddenly under stress when going beyond the service life limitations and therefore the hydraulic tightening machine is damaged and operators are injured is successfully avoided.
Description
Technical field
The present invention relates to a kind of counting mechanism of fluid pressure type tightening machine, be applicable to record variously tight a bolt, the scientific and technical product of the actual access times of the fluid pressure type tightening machine of nut.
Background technology
In current industrial equipment, equipment, the especially connection between the key components and parts of Large-Scale Equipment, great majority are to adopt bolt and nut to connect.For example: steam power plant, hydro-electric power generating equipment, nuclear power generating equipment, wind power generating set equipment, metallurgical equipment, mining equiment, shipbuilding equipment, petrochemical equipment etc. have the connection of thousands of large-sized bolt for its key components and parts.These bolts all need to tighten and dismantle with the instruments such as fluid pressure type tightening machine or equipment, equate to guarantee that the pretightning force of each connecting bolt, nut is tried one's best, and guarantee that equipment component is by effective, safety, connection reliably.These bolts connections are all being used thousands of fluid pressure type tightening machine in fastening and dismounting all the time.All there is following problem in the instruments such as existing fluid pressure type tightening machine or equipment: the actual access times of fluid pressure type tightening machine cannot track record, and the orthochronous that can not reach before lifetime limitation at rapid wear component of machine is changed in time.Described problem causes a lot of fluid pressure type tightening machine in production work process, just to know that rapid wear component of machine needs replacing suddenly fracture in the situation that using rapid wear component of machine, and this usually causes instrument or the damage of equipment and operating personnel's the casualty accidents such as fluid pressure type tightening machine.
The fluid pressure type tightening machine existing in the world is at present being used after certain hour, and rapid wear mechanical part will produce mechanical fatigue, thereby can cause unexpected fracture or damage.Owing to can not effectively following the tracks of the actual access times of fluid pressure type tightening machine, cannot when should change stressed rapid wear mechanical part by accurately predicting, usually cause fluid pressure type tightening machine fracture suddenly or damage in production work use procedure, and cause instrument or the damage of equipment and operating personnel's the casualty accidents such as fluid pressure type tightening machine.
Summary of the invention
In view of the ubiquitous serious safety problem of above international and domestic fluid pressure type tightening machine, the object of the present invention is to provide a kind of counting mechanism of fluid pressure type tightening machine, user can carry out real-time tracking record to the actual access times of fluid pressure type tightening machine like a cork, so that can change in time according to this counting record the stressed rapid wear mechanical part of fluid pressure type tightening machine.
Concrete technical scheme is as follows:
A kind of counting mechanism of fluid pressure type tightening machine, described fluid pressure type tightening machine comprises inlet and outlet of fuel channel mechanism, described counting mechanism comprises: counting mechanism body, in be located at the intrinsic driving mechanism of described counting mechanism, under the promotion of described driving mechanism, count the counter of work, and the body lower cover of fixing described counter, described body lower cover is connected with described counting mechanism body by the draw-in groove on described counting mechanism body;
Described driving mechanism comprises and inserts described counting mechanism intrinsic driven plunger, is set in spring mechanism in described driven plunger, is threaded connection and inserts the piston limit pin in the stopper slot of described driven plunger with described counting mechanism body, and described piston limit pin can only axially seesaw described driven plunger and can not rotate;
Described spring mechanism comprises spring and spring capping, and described spring capping and described counting mechanism body are threaded connection; The thimble of described counter inserts described spring capping and is connected with described driven plunger.
Described counting mechanism is connected with described fluid pressure type tightening machine by lock bolt.
In the seal groove of described driven plunger, there is piston seal.
Described inlet and outlet of fuel channel mechanism is connected with described fluid pressure type tightening machine by described counting mechanism.
Described inlet and outlet of fuel channel mechanism is connected by gland with described counting mechanism body; The oil pocket that arrives described fluid pressure type tightening machine through described inlet and outlet of fuel channel mechanism when hydraulic oil once, described in the pressure-driven of described hydraulic oil, driven plunger moves outward, during to the compression limit position of described spring, stop the now described counting mechanism once work of described fluid pressure type tightening machine of record automatically.
After described hydraulic oil pressure release, get back to described inlet and outlet of fuel channel mechanism through described counting mechanism body, described driven plunger back moves and resets under the effect of the screen resilience of described spring, drives described driven plunger back move and reset simultaneously.
Described driven plunger outward movment and resetting under the screen resilience effect of described spring under pressure-driven, the every circulation primary of this process, described counter records one secondary data.
Compared with prior art, the invention has the beneficial effects as follows:
The counting mechanism of this invention fluid pressure type tightening machine has successfully solved the problem that the actual access times of the fluid pressure type tightening machine always existing in the world today cannot tracked record.The counting mechanism of fluid pressure type tightening machine of the present invention passes in and out a circulation in fluid pressure type tightening machine system according to hydraulic oil be exactly the actual expendable principle of fluid pressure type tightening machine, uses accurate counting mechanism design track record fluid pressure type tightening machine real work access times.The in the situation that of realizing Operation and Maintenance personnel before fluid pressure type tightening machine rapid wear mechanical part reaches design service life and do not damage, change in advance rapid wear mechanical part, the unexpected fracture when successfully having avoided fluid pressure type tightening machine in use stressed rapid wear mechanical part reaching lifetime limitation causes device damage and operating personnel's injury.Solve and go up both at home and abroad an existing moment of torsion tightening tool and equipment difficult problem for existence always in the actual use work at present.
