Description
Technical field
The utility model relates to hydraulic spanner, especially a kind of hollow hydraumatic spanner.
Background technology
Hollow hydraumatic spanner is used to a kind of hydraulic tool of pretension or dismounting high-strength bolt nut, and it is widely used in the field such as electric power (nuclear power, wind-powered electricity generation, water power, thermoelectricity), boats and ships, metallurgy, traffic, cement, building, aviation.Its feature is: adopt superhigh intensity light metal, thin design, double acting, and at a high speed, large corner plug-in, exchanges working head, do not need special tool(s), and moment of torsion repeatable accuracy, up to ± 3%, is applicable to compact occasion, convenient location.
Current hollow hydraumatic spanner, as shown in Fig. 5, Fig. 6, Fig. 7: 1, the two sides, front and back of oil cylinder left end is the outside being connected to front and back outer baffle-plate by fixture, like this, the width of oil cylinder is just greater than the distance between former and later two outer baffle-plates.When the hollow hydraumatic spanner dismounting of this structure or pretensioning device, relatively good use when being in the bolt of corner location, if but the bolt that dismounting or pretension mediate, because the outer surface of oil cylinder and outer baffle is not in same level, need below outer baffle, add a cushion block, otherwise meeting run-off the straight, six sides of spanner ratchet and six side's contact surfaces of bolt and nut will reduce, be unfavorable for that transmission is stressed, easy damage transmission mechanism, affect dismounting or the pretensioning effect of bolt, also shorten the service life of spanner simultaneously; 2, running part is bastard structure, and transmission accuracy is low, transmission efficiency is poor.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel hollow hydraumatic spanner, and it is easy to use, can not damage transmission mechanism, ensures dismounting or the pretensioning effect of bolt and nut.Meanwhile, this novel hydraulic spanner can extend its service life.
A kind of easy to operate hollow hydraumatic spanner of the utility model, it comprises front and back outer baffle, oil cylinder, swivel joint, piston rod, gib head, transmission mechanism; Before and after the upper right side of the outer baffle arc surface that has one to cave in, the left side of oil cylinder is a cambered outwards arc surface, front and back outer baffle and oil cylinder are fastened by arc surface, and the two sides, front and back of the outside of front and back outer baffle-plate and oil cylinder at grade, swivel joint is connected on oil cylinder, in oil cylinder, the front end of piston rod is fixedly connected with gib head, and transmission mechanism is arranged between the outer baffle of front and back, and is connected with gib head.
The utility model, by front and back outer baffle and oil cylinder are set to arc surface snap-in structure, makes the two sides, front and back of the outside of front and back outer baffle-plate and oil cylinder at grade.Like this, when carrying out pretension or dismounting to the bolt and nut mediated, there will not be inclination, do not need to pad cushion block, pretension or dismounting can be carried out conveniently by ratchet to card bolt and nut within it.Simultaneously; two ends due to ratchet are arranged in the hole of front and back outer baffle; the width of its entirety is wider relative to existing spanner; therefore six sides of ratchet can fully contact with six of bolt and nut; contact surface change is conducive to greatly transmitting stressed, protection transmission mechanism; pretension and the dismounting effect of bolt and nut can be ensured, its service life can be extended again.

Detailed description of the invention
From Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of easy to operate hollow hydraumatic spanner of the utility model, it comprises front and back outer baffle 1, oil cylinder 2, swivel joint 3, piston rod 8, gib head 7, transmission mechanism; Before and after the upper right side of outer baffle 1 arc surface that has one to cave in, the left side of oil cylinder 2 is a cambered outwards arc surface, front and back outer baffle 1 is fastened by arc surface with oil cylinder 2, and the two sides, front and back of the outside of front and back outer baffle-plate and oil cylinder at grade, swivel joint 3 is connected on oil cylinder 2, the front end of oil cylinder 2 li of piston rods 8 is fixedly connected with gib head 7, and transmission mechanism is arranged between front and back outer baffle 1, and is connected with gib head 7.In order to ensure the connection between oil cylinder and front and back outer baffle further, be connected by pin 5 between oil cylinder 2 with front and back outer baffle 1.
Wherein, this novel transmission mechanism comprises serration ratchet 4, force transmitting board 6, ratchet 9, and serration ratchet 4 is arranged on force transmitting board 6, and gib head 7 hangs on the pin of force transmitting board 6, and ratchet 9 is arranged in the groove above force transmitting board 6, and engages with serration ratchet 4.This novel running part have employed serration ratchet, and transmission accuracy is high, and transmission efficiency is good.
The operation principle of the utility model hydraulic spanner is as follows: hydraulic pump hydraulic oil out enters the rodless cavity of oil cylinder 2 by swivel joint 3, promote piston 8 to move right, gib head 7 promotes force transmitting board 6, force transmitting board 6 promotes ratchet 9, ratchet 9 promotes serration ratchet 4, and serration ratchet 4 promotes bolt and nut and rotates; When piston 8 arrives limit on the left, pumping plant commutates, and rod chamber comes oily, rodless cavity oil return, and piston moves right, and drives force transmitting board and ratchet to move right by gib head and bearing pin, so repeatedly, thus the object reaching tools for bolts ' pretension or dismantle.
The utility model, by front and back outer baffle 1 and oil cylinder 2 are set to arc surface snap-in structure, makes the two sides, front and back of the outside of front and back outer baffle-plate 1 and oil cylinder 2 at grade.Like this, when carrying out pretension or dismounting to the bolt mediated, there will not be inclination, do not need to pad cushion block, pretension or dismounting can be carried out conveniently by ratchet to card bolt and nut within it.Meanwhile, because six sides of the ratchet of spanner can fully contact with six of bolt and nut, be conducive to transmission stressed, pretension and the dismounting effect of bolt and nut can be ensured, its service life can be extended again.
