Abstract
The invention discloses a two-leg wrench for detaching a round nut with a hole in an end face. The wrench comprises a front cylinder head, a rear cylinder head, a ladder-shaped slide block, a wrench support, a fixed bolt and a bolt pull rod, wherein the wrench support comprises a jaw and a handle, a front cylindrical hole is formed at the front end of the semi-circular jaw for assembling the front cylinder head, and the rear end of the jaw is integrally cast with the handle; a screwed through hole is formed on the upper part of the flat rectangular handle, and the fixed bolt is arranged in the screwed through hole; a dovetail groove is formed inside the handle, and the ladder-shaped slide block is arranged in the dovetail groove; a rear cylindrical hole is formed at the front end of the ladder-shaped slide block for assembling the rear cylinder head, and a bolt hole is formed on the tail end of the rear end of the ladder-shaped slide block; and the bolt pull rod is arranged in the bolt hole. The two-leg wrench has a simple structure, is convenient to adjust, has relative larger applied moment, and can be used as well when the shaft extends from the nut much longer.
Description
Technical field
The present invention relates to a kind of spanner, particularly a kind of bipod spanner of dismantling end face round nut with holes.
Background technology
When the dismounting of electric main shaft maintenance, often need dismounting end face round nut with holes, the characteristics of the end-face hole of this end face round nut with holes are to have at least on two extended lines that are distributed in the round nut diameter of bore.Because the round nut endoporus has main shaft to stretch out, so general spanner can't use.At present, what often use is the bipod spanner that is acute angle, and this bipod spanner applies the moment difficulty, and inconvenience is according to the openings of sizes of the end-face hole distance adjustment bipod on the round nut end face.In addition, also useful nail oblique cutting is in the round nut end-face hole, and the method for knocking with hammer, but this method is very undesirable, because impulsive force is very big, damages round nut end-face hole and nut tooth line easily makes troubles and causes unnecessary economic loss to dismounting.
Summary of the invention
Defective at the prior art existence, the purpose of this invention is to provide a kind of bipod spanner of dismantling end face round nut with holes, the end face that when the round nut endoporus has main shaft to stretch out, still can use round nut with holes dismounting spanner particularly, realize easy to adjust, apply advantages such as moment is easy.
For achieving the above object, technical scheme of the present invention is:
A kind of bipod spanner of dismantling end face round nut with holes, comprise preceding socket cap, back socket cap, trapezoidal slide block, spanner frame, hold-down screw and screw draw bar, described spanner frame comprises jaw and handle, described jaw semicircular in shape, cylindrical hole was used to install described preceding socket cap before its front end had, and rear end and described handle monoblock cast form; Described handle is flat cuboid, and its top has a tapped through hole, cooperates in the described tapped through hole a described hold-down screw is installed; Described handle inside has a dovetail groove, a described trapezoidal slide block is installed in the described dovetail groove, the front end of described trapezoidal slide block has the back cylindrical hole and is used to install described back socket cap, and the rear end has a screw hole at afterbody, cooperates in the described screw hole a described screw draw bar is installed.
Spur described screw draw bar and regulate the distance of described preceding socket cap and described back socket cap, the described hold-down screw of tightening described handle top when distance is moderate secures the above trapezoidal slide block, socket cap before described and described back socket cap are put into corresponding round nut end-face hole, apply moment dismounting end face round nut with holes at described handle.
The present invention has following outstanding advantage compared with prior art:
This spanner can be dismantled the end face round nut with holes that the round nut endoporus has main shaft to stretch out, and the same arm of force applies same power, and the common bipod of the torque ratio of generation is pulled greatly.The distance of regulating two socket caps by the screw draw bar of pulling slide block rear end, and can tighten the position of hold-down screw fast with fixing trapezoidal slide block, easy to adjust.

The specific embodiment
Below in conjunction with the drawings and specific embodiments embodiments of the invention are described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of bipod spanner of dismantling end face round nut with holes, socket cap 1, back socket cap 3, trapezoidal slide block 4, spanner frame 5, hold-down screw 6 and screw draw bar 8 before comprising, described spanner frame 5 comprises jaw 2 and handle 7, described jaw 2 semicirculars in shape, cylindrical hole 9 was used to install described preceding socket cap 1 before its front end had, and rear end and 7 monoblock casts of described handle form; Preceding cylindrical hole 9 and preceding socket cap 1 adopt interference fit, and described handle 7 is flat cuboid, and its top has a tapped through hole 10, cooperate in the described tapped through hole 10 described hold-down screws 6 are installed; Described handle 7 inside have a dovetail groove 11, in the described dovetail groove 11 a described trapezoidal slide block 4 is installed, the front end of described trapezoidal slide block 4 has back cylindrical hole 12 and is used to install described back socket cap 3, back cylindrical hole 12 and back socket cap 3 adopt interference fit, the rear end has a screw hole 13 at afterbody, cooperates in the described screw hole 13 a described screw draw bar 8 is installed.
When on handle, applying moment and be not enough to twist nut, can on handle, overlap a steel pipe and prolong the arm of force, and then increase moment with conveniently fast disassembling end face round nut with holes.
Referring to Fig. 4, during work, spur described screw draw bar 8 and regulate the distance of described preceding socket cap 1 and described back socket cap 3, the described hold-down screw 6 of tightening described handle 7 tops when distance is moderate secures the above trapezoidal slide block 4, socket cap 1 before described and described back socket cap 3 are put into corresponding round nut end-face hole, apply moment dismounting end face round nut with holes at described handle 7.
