Abstract
The utility model discloses an adjustable hook wrench suitable for screwing of main shaft extension rod nuts of machine tools of different dimensions in a narrow environment. The wrench comprises a stud body, a hook body and an adjustable screw, wherein the stud body is provided with a thread through hole along an axis; one end of the stud body is provided with a U-shaped groove; one end of the hook body is welded in the U-shaped groove and the other end of the hook body is threaded-connected with a hook; the adjustable screw is threaded-connected to the thread through hole close to one end of the hook body; when the adjustable hook wrench is in use, the hook is inserted into a light hole of the main shaft extension rod nut; an end surface of the adjustable nut is abutted against the main shaft extension nut and forms a mutual-clamped position via a rotation of the adjustable screw; an axis of the hook and an axis of the adjustable screw form an included angle of about 135 degrees; and one end of the thread through hole far away from the hook body is provided with an extension bar facilitating long distance holding. By the use of an adjustable hook wrench, a screwing of main shaft extension rod nut with different dimensions in a narrow place can also be easily operated.
Description
Technical field
The utility model relates to a kind of spanner of mechanical manufacturing field, particularly a kind of adjustable hook spanner that is fit to different size main shaft extension bar nut.
Background technology
During machine-building processing porous series in order to reduce labour intensity, enhance productivity, generally all adopt special purpose transfer machine processing, according to varying in size of the same processing face of processing, lathe headstock arranges many main shafts not of uniform size usually, and many main shaft extension bar nuts not of uniform size are so just arranged.For the tightening method of the closeer main shaft extension bar nut of this layout, can only adopt extension bar to strike tight method with iron hammer usually, workman's operation is very inconvenient.
The utility model content
The utility model is in order to overcome defective in the above-mentioned prior art, and by designing adjustable hook spanner, the main shaft extension bar nut of different size still can conveniently be tightened in narrow and small position in the space.
For realizing above-mentioned utility model purpose, the utility model provides a kind of adjustable hook spanner, is applicable to the tightening of machine tool chief axis extension bar nut of the different size in the narrow and small environment in space, comprising: spiro column, it is provided with tapped through hole along axis, and spiro column one end is provided with U-shaped groove; Hook-shape body, one end are welded in the U-shaped groove, the other end hook that is threaded; Adjustment screw, it is threaded in spiro column near in the tapped through hole of hook-shape body one end; When adjustable hook spanner used, hook was plugged in the unthreaded hole of main shaft extension bar nut, made the formation clamping that connects of the end face of adjusting nut and main shaft extension bar nut by the rotation adjustment screw.
In the technique scheme, the axis of hook and the axis angle of adjustment screw are about 135 degree.
In the technique scheme, tapped through hole is provided with extension bar away from an end of hook-shape body, is convenient to control at a distance.
Compared with prior art, the utlity model has following beneficial effect:
1, adjustable hook spanner of the present utility model is specially adapted to arrange tightening of closeer main shaft extension bar nut, and the zone narrow and small in the space can be suitable for tightening of the big or small extension bar nut of various differences;
2, simple in structure, easy to operate.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
As shown in Figure 1, adjustable hook spanner of the present utility model comprises spiro column 1 and hook-shape body 2, one end of hook-shape body 2 is welded in the U-shaped groove of offering on the spiro column 1 11 (referring to Fig. 2-1 and Fig. 2-2), unsettled and the free end of the other end of hook-shape body 2 is provided with installs screw 21, the hook 3 that is threaded in the screw 21 is installed, and the angle between the axis of hook 3 and adjustment screw 4 axis is about 135 degree.Spiro column 1 is processed a tapped through hole vertically, and tapped through hole is provided with adjustment screw 4 near an end of hook-shape body 2, and the other end of tapped through hole is installed an extension bar 5, is convenient to controlling and remote-controlled operation of adjustable hook spanner.
Further as shown in Figure 3, when using adjustable hook spanner of the present utility model to tighten main shaft extension bar nut 6, earlier hook 3 is inserted in the unthreaded hole of main shaft extension bar nut 6, screw out adjustment screw 4 then and make the end face of adjustment screw 4 and main shaft extension bar nut 6 butts form clamping, rotate extension bar 5 and can easily realize screwing of main shaft extension bar nut 6.
Adjustable hook spanner of the present utility model is specially adapted to arrange tightening of closeer main shaft extension bar nut that narrow and small zone can be suitable for tightening of the big or small extension bar nut of various differences in the space, and is simple in structure, easy to operate.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
