Description

Be applicable to that retaining part is the part adjustable spanner that is threaded on the smooth face of cylinder

Technical field

The present invention relates to a kind of adjustable spanner, particularly a kind of suitable retaining part is the part adjustable spanner that is threaded on the smooth face of cylinder.

Background technology

The joint of mechanisms such as articulated robot or articulated type coordinate measuring machine will be used an axle type and a cover parts usually, and the surface of these parts is normally columniform, and between less joint axis class of size and cover parts, often adopts and be threaded.

The columniform part that is threaded is processed into outer-hexagonal or interior hexagonal configuration to the part of part, so that screw with common wrench or inner hexagon spanner usually in order to screw needs; But some part is because attractive in appearance or structural requirement, and when not allowing to process the structure of outer-hexagonal and interior hexagonal configuration, common way is at end face or radially processes some fabrication holes, and uses scroll chuck spanner or other similar spanner to screw; But but also have some parts since to the very high retaining part width of appearance requirement factor such as narrower or undercapacity and do not allow the processing technology hole; Thereby cause and to screw with the spanner and the scroll chuck of routine; The mode that article such as the leather that frictional force is stronger on the general at present employing staff pad, rubber are screwed; This mode is time-consuming, require great effort and be difficult to and tighten, and because the discontinuity of retaining part causes part deformation easily.

Summary of the invention

Existing spanner can't be screwed no fabrication hole and retaining part is the problem of the part that is threaded on the smooth face of cylinder in order to solve, and the object of the present invention is to provide a kind of retaining part that is applicable to is the part adjustable spanner that is threaded on the smooth face of cylinder.

Adjustable spanner of the present invention comprises handle 1, clamping collar 2 and pin pawl 3, and clamping collar 2 is installed on the handle 1, and pin pawl 3 is installed on the clamping collar 2.

Handle described in the present invention 1 is " Y " shape handle, has U-lag in the end of its Y shape handle.

Clamping collar described in the present invention 2 is made up of two semicircular collars 4; Each collar is provided with gathering sill 5; Two collar 4 one ends are installed in the U-lag of handle 1 through alignment pin 6; And can be around alignment pin 6 rotations in U-lag, the other end connects through bolt 7, and pin pawl 3 is arranged in the gathering sill 5.

The pawl 3 of pin described in the present invention comprises corpus unguis 8, the axis of guide 9 and pin palmula 10; Corpus unguis 8 is connected with the axis of guide 9; The axis of guide 9 is installed in the gathering sill 5 through nut; Pin palmula 10 is installed in the swallow tail shaped slot of corpus unguis 8 front ends, is contacted in order to directly to screw part with quilt, and produces the moment of friction when screwing; Pin pawl 3 can move in the gathering sill 5 of clamping collar 2 through the axis of guide 9 of himself; The first half of the axis of guide 9 is processed with screw thread; Pin pawl 3 can be by the axis of guide 9 and the optional position of nut check in gathering sill.

Pin pawl 3 has the diameter and the width of different size, can select for use according to the diameter and the width of being screwed the part retaining part.

The beneficial effect that the present invention has is:

1, the pin pawl that can select different size for use according to the diameter of being screwed the part retaining part and width dimensions.

2, the quantity and the position of pin pawl can change according to actual conditions, thereby are applied to the part that retaining part has different structure.

3, the end of pin pawl is equipped with the pin palmula that non-metallic elastic material is made, and can increase the moment of friction when screwing, and prevents to screw that time pin pawl scratches piece surface.

4, this apparatus structure is simple, and is easy to operate, be applicable to screw the part that is threaded that retaining part is the smooth face of cylinder, when screwing part stressed more evenly, not yielding, and be difficult for injuring part.

5, this device is specially adapted to the part that is threaded that the retaining part width is narrower, diameter is less, with the problem that solves staff and all inconvenient clamping of general tool, screws.
