Abstract

The utility model discloses a round-nut fastening wrench which comprises a wrench head and a handle which are integrally made of steel. The wrench head comprises a disc-shaped fixing plate and a plurality of guide pillars fixed on one side of the fixing plate and integrally perpendicular to the surface of the fixing plate, and the guide pillars are cylindrical and are evenly distributed along the circumference concentric to the center of the fixing plate. The round-nut fastening wrench has the advantages that a round nut can be screwed or unscrewed within a narrow space, and convenience in use can be achieved.

Description

A kind of round nut spanner
Technical field
The utility model relates to a kind of instrument, relates in particular to a kind of round nut spanner.
Background technology
In the press workshop of factory, need to carry out maintenance repair to forcing press, in the securing member of these equipment, often can comprise some round nuts, common instrument is difficult to these nuts to back-out.Existing method is mainly that pin is first screwed in the hole that round nut end face opens, and then prizes screw rod with crowbar in outside and realizes and screw or back-out.This method operates and extremely requires great effort bothersomely, and one carrys out the fixing of pin relatively loses time, and two carry out sometimes this class instrument of crowbar sometimes cannot use in foundation ditch or this narrow space of slide block at all.
Therefore just need a kind of size less, be adapted at using in this narrow space of foundation ditch or slide block, conveniently the securing member of forcing press one kind equipment is screwed or the round nut spanner of operation of back-outing.
Utility model content
The utility model operates the comparatively deficiency of inconvenience to round nut, the round nut spanner that provides a kind of convenience to use at small space, conveniently round nut is operated in order to overcome existing instrument.To achieve these goals, the utility model is by the following technical solutions:
A kind of round nut spanner, comprise the driving end, the handle that are made into integration by steel, described driving end comprises that fixed disk in the form of annular discs, described fixed disk are provided with some guide pillars perpendicular to fixed disk surface on one side integratedly, described guide pillar is cylindric, and guide pillar is along the even circumferential distribution concentric with the fixed disk center of circle.
The utility model is in order to overcome existing instrument to the unhandy deficiency of round nut, the cylindric guide pillar on driving end for stretch in the circular hole on round nut end face and with its matched in clearance.When use, the guide pillar on driving end is aimed to the circular hole on round nut end face, and stretched into circular hole, hold again handle and do clockwise or counterclockwise rotation, can realize easily the operation that screws or back-out for round nut, thereby realize the purpose of this utility model.
As preferably, described fixed disk diameter is 80mm to 100mm, and fixed disk is provided with manhole, and described through hole is concentric with the fixed disk center of circle.Fixed disk can match with the external diameter of round nut like this, easy to use; Through hole on fixed disk had both been saved material, had reduced production cost, had also reduced the stress producing when fixed disk uses, the service life of having improved instrument.
As preferably, described through-hole diameter is 50mm to 55mm.
As preferably, guide pillar quantity is 3 to 6.For the quantity of circular hole on different round nut end faces, make the spanner that is applicable to different round nuts like this, improved the applicability of instrument.
As preferably, described guide pillar length is 10mm to 30mm.Guarantee that like this guide pillar stretches in the circular hole of round nut end face fully, make the combination of spanner and round nut more firm, easy to use.
As preferably, described guide pillar diameter of section is greater than 10mm, is less than 15mm.So both can guarantee that guide pillar can stretch in the circular hole of round nut, guarantee again that guide pillar itself had some strength, and be difficult in use fractureing, increase the service life of instrument, and be easy to use simultaneously.
As preferably, described guide pillar upper surface is provided with chamfering.Make like this guide pillar can stretch into more easily in the circular hole of round nut end face, easy to use.
As preferably, described chamfering is 30 degree to 60 degree, and the long straight flange of chamfering is 0.5mm to 2mm.
As preferably, described handle is rectangular tabular, and decreased food is 200mm to 300mm, and handle width is 30mm to 70mm.Can make like this size of whole spanner less, can be easily in foundation ditch or the comparatively narrow space of this class of slide block, use.
As preferably, described handle tail end both side surface is provided with anti-skidding lines.Anti-skidding lines be arranged so that spanner use time, be difficult for skidding, further facilitate operating personnel use.
The utility model has the advantage of: can in narrow space, screw round nut or the operation of back-outing, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As Fig. 1, in embodiment shown in Fig. 2, a kind of round nut spanner, comprise the driving end being made into integration by steel, handle 1, described driving end comprises fixed disk in the form of annular discs 2, described fixed disk diameter is 80mm to 100mm, in embodiment, be 90mm, fixed disk is provided with manhole 4, described through hole is concentric with the fixed disk center of circle, through-hole diameter is 50mm to 55mm, in embodiment, be 50mm, on fixed disk one side, be provided with some guide pillars 3 perpendicular to fixed disk surface integratedly, the quantity of described guide pillar is 3 to 6, in embodiment, be 6, it is cylindric that guide pillar is, its diameter of section is greater than 10mm, be less than 15mm, in embodiment, be 10mm, guide pillar length is 10mm to 30mm, in embodiment, be 20mm, guide pillar upper surface is provided with chamfering 5, described chamfering is 30 degree to 60 degree, in embodiment, be 45 degree, the long straight flange of chamfering is 0.5mm to 2mm, in embodiment, be 1mm, guide pillar guide pillar is along the even circumferential distribution concentric with the fixed disk center of circle, described handle is rectangular tabular, thickness is 10mm to 20mm, in embodiment, be 20mm, length is 200mm to 300mm, in embodiment, be 200mm, width is 30mm to 70mm.In embodiment, be 50mm, handle tail end both side surface is provided with anti-skidding lines 6.
When the utility model uses, the guide pillar on driving end is aimed to the circular hole on round nut end face, and guide pillar is stretched in circular hole, then hold handle and do clockwise or counterclockwise rotation, can realize easily the operation that screws or back-out for round nut.The utlity model has and can in narrow space, screw round nut or the operation of back-outing, use beneficial effect comparatively easily.
