Abstract
The utility model relates to a socket spanner, in particular to a bolt screwing tool. The bolt screwing tool comprises a positioning rod which is a screw rod. One end of the positioning rod is connected with a protection sleeve which is a hollow cylinder. The protection sleeve is in threaded connection with the positioning rod. The other end of the positioning rod is connected with a handle. The handle is in threaded connection with the positioning rod. The bolt screwing tool has the advantages of being simple in structure, convenient to use, suitable for application and popularization, capable of effectively preventing welding slag generated in welding from falling into an inner ring of a nut and the like.
Description
Technical field
The utility model relates to a kind of box spanner, especially relates to a kind of tightening tool of bolt.
Background technology
Very general welding method while using welding rod welding, but when welding, can produce welding slag on a large scale splashes, welding slag often splashes everywhere from weld, part welding slag can drop on nut inner ring, affect coordinating of subsequent parts and nut thread, the screw thread also can butt welding before assembling connecting carries out tapping processing, but waste time and energy, increase operation, and the orientation tool of existing welding projection welding nut generally only plays auxiliary positioning effect, can not prevent that welding slag from falling on nut inner ring, simultaneously, this device volume is larger, operates comparatively loaded down with trivial detailsly, is not suitable for using on a large scale.
Summary of the invention
The utility model is mainly that existing welding orientation tool can not prevent that welding slag from falling on nut inner ring during for existing nut-welding, can affect the problem of follow-up assembling, provide a kind of use simple, suitable promoting the use of, the welding slag producing in the time of can preventing from welding falls into the tightening tool of the bolt on nut inner ring.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of tightening tool of bolt, comprise backstay, described backstay is screw rod, one end of backstay is connected with sheath, described sheath is hollow cylinder, sheath is threaded with backstay, and the other end of backstay is connected with handle, and handle is threaded with described backstay.When the utility model is a kind of welding projection welding nut, can effectively prevent that welding slag from falling into the orientation tool of nut, screw rod is connected with nut through project-welding nut preformed hole on sheet metal component, exposes one section, nut and is connected with sheath.Because nut inner ring has backstay, nut and backstay thread gaps are protected by sheath, so this positioner can stop welding slag to enter nut inner ring.During welded nut, with hand, catch handle to operate this positioner, can be convenient nut is welded to location, avoid screw thread on screw rod to scratch user's hand simultaneously.
As preferably, one end of described sheath sealing.The sealing of sheath one end, an end opening, openend is threaded with backstay, and one end of sealing can better prevent that welding slag from falling into screw thread inner ring.
As preferably, in the middle part of described backstay, be provided with locating ring.It is slightly longer that backstay should be manufactured, locating ring is divided into two parts by backstay, a part is connected with nut, another part is connected with handle, if the part thread damage being connected with nut like this, can turn round and use the part being connected with handle is the one end of working, and can use for a long time and save man-hour.Handle end contacts with locating ring, and locating ring plays position-limiting action to handle, and handle can double swerve, can better position the welding of nut.
As preferably, the interlude of described locating shaft is optical axis, and it is inner that described optical axis is positioned at described locating ring.When hand is grabbed handle, optical axis opponent can not damage.Optical axis stress is little, and intensity is high, not frangibility.
As preferably, described handle is "T"-shaped."T"-shaped handle is comparatively common, and technical maturity is manufactured simply, and met people's use habit.
Therefore, the utlity model has simple in structure, easy to use, suitable promoting the use of, the welding slag producing in the time of can effectively preventing from welding falls into the advantages such as nut inner ring.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
A kind of structural representation when accompanying drawing 2 is the utility model use.
Shown in figure: 1-backstay, 2-sheath, 3-handle, 4-locating ring, 5-optical axis, 6-welding panel beating, 7-nut, 8-preformed hole, 9-solder joint.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure of description 1,2, a kind of tightening tool of bolt, comprises backstay 1, backstay is screw rod, one end of backstay is connected with sheath 3, and sheath is tapped hollow cylinder, and one end of sheath is sealed, sheath is threaded with backstay, backstay middle part is provided with locating ring 4, and the interlude of locating shaft is optical axis 5, and optical axis is uniformly distributed in locating ring both sides, the other end of backstay is connected with "T"-shaped handle 2, and handle is threaded with locating shaft.
During use, handle is inserted in backstay, contact with locating ring to handle, the other end of backstay stretches in the preformed hole 8 of welding panel beating 6, nut 7 passes backstay and tightens, backstay stretches out the part of nut to be tightened with sheath, and hand is grabbed handle makes orientation tool position the projection welding of nut, can carry out gas and weld.During welding, backstay and sheath can protect the welding slag that is splashed out by solder joint 9 can not fall on the inner ring of nut, therefore can not affect the assembling of welded nut He other parts.
Should be understood that this embodiment is only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
