Abstract
The utility model discloses a three -jaw spanner with adjustable relates to the three -jaw spanner with adjustable who is used for DF4D type locomotive diesel engine installation PLASTIC LAMINATED. It mainly is that to solve the hexagonal nut that the PLASTIC LAMINATED that compresses tightly at present on the diesel engine cylinder used not of uniform size, and the space between the diesel engine cylinder shroud is narrow and small, gives screwing up of interior hexagonal nut and brings the difficulty, and work efficiency is low, screws up the poor problem of effect. The utility model discloses a wrench body is a pipe, and one of pipe is served and is equipped with the slide bar, is equipped with three jack catch on the other end of pipe, and three jack catch passes through the screw slope and connects on the pipe. The utility model discloses a wrench body adopts the tubular structure, can improve the bulk strength, and weight reduction adopts threaded connection between the jack catch of spanner and the wrench body, and the extension amount of jack catch can adjust, can increase the reducing scope, the utility model provides high speed of screwing up PLASTIC LAMINATED fixation nut has guaranteed to screw up moment.
Description
Technical field
This utility model is related to a kind of adjustable three-jaw spanner, relates particularly to install for DF4D types diesel engine of locomotive
The adjustable three-jaw spanner of PLASTIC LAMINATED.
Background technology
For improving diesel engine of locomotive safety in operation, diesel engine of locomotive all adds PLASTIC LAMINATED, and PLASTIC LAMINATED passes through
Thin hexagonal nut is pressed on cylinder of diesel engine bolt.Due to six sides that each locomotive depot of Railway Bureau and each place railroad use
Nut is not of uniform size, and the narrow space between cylinder cap for diesel engine, brings many difficulties, work to tightening for interior six square nuts
Make efficiency low, tighten effect poor.
The content of the invention
The purpose of this utility model be for above-mentioned deficiency, and propose a kind of highly versatile, it is adaptable to different size
Nut, the speed for tightening PLASTIC LAMINATED fixing nut can be improved, it is ensured that screw-down torque, high working efficiency tightens effect good
Adjustable three-jaw spanner.
Technical solution of the present utility model is：Wrench body is a pipe, and one end of pipe is provided with slide bar, manages
The other end of son is provided with three claws, and three claws are inclined by screw thread and are connected on pipe.
The side wall of the pipe described in technical solution of the present utility model is provided with and is mutually inclined with the central axis of pipe
Three oblique screwed holes, three claws pass through being threaded on three screwed holes of pipe in its one end respectively, by lock
Tight nut is locked at claw on pipe.
Slide bar described in technical solution of the present utility model is connected in the radial hole on pipe.
The internal diameter of the pipe described in technical solution of the present utility model is outer more than cylinder of diesel engine cylinder head bolt
Footpath, the length of pipe are more than the height of cylinder of diesel engine cylinder cap.
The on-fixed end of the claw described in technical solution of the present utility model is provided with the square tenon of bias.
Wrench body of the present utility model adopts tubular structure, can improve bulk strength, mitigates weight, the claw of spanner
Using threaded connection and wrench body between, the overhang of claw can be adjusted, and can increase reducing scope；This utility model is carried
The high speed for tightening PLASTIC LAMINATED fixing nut, it is ensured that screw-down torque.
Description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the part sectioned view that wrench body is connected with claw.
Fig. 4 is the axonometric chart of claw front end bias side tenon.
Specific embodiment
As shown in Figure 1,2,3, 4, spanner of the present utility model includes a pipe 1, can improve whole using tubular structure
Body intensity, mitigates weight；The internal diameter of pipe 1 can avoid bolt cylinder end more than the external diameter of cylinder of diesel engine cylinder head bolt
Interference, the length of pipe 1 can avoid the interference of cylinder cap more than the height of cylinder of diesel engine cylinder cap；Set on one end of pipe 1
There is slide bar 2, slide bar 2 is connected in the radial hole on pipe 1, and slide bar 2 can slide along the hole on pipe 1, can be with by slide bar 2
Moment of torsion is applied to pipe 1, and the interference of diesel engine charge air cooler can be avoided；Three claws 3 are connected with the other end of pipe 1, are managed
The side wall at sub 1 end is provided with three downward screwed holes, and three screwed holes are obliquely installed with the central axis of pipe 1, three
Claw 3 is respectively by being threaded on three screwed holes of pipe 1 in its one end, and locks claw 3 by locking nut 4
Tightly on pipe 1, as shown in Figure 2,3, the overhang of claw 3 can be adjusted using threaded connection, to increase the reducing model of claw 3
Enclose, the central axis of 3 versus tube 1 of claw has certain inclination angle, to reduce maximum radial dimension, improve spanner intensity, avoid
The interference of cylinder cap for diesel engine, and reach the reducing of claw 3；The on-fixed end of the front end of claw 3, i.e. claw 3 is provided with one
Eccentric square tenon 5, as shown in figure 4, the work that can also change claw 3 to a certain extent by the rotation of eccentric structure is straight
Footpath；Claw 3 can be locked on pipe 1 by eccentric square tenon 5 and locking nut 4.
