The utility model relates to a bolt tightening device, be in including the tight frame of clamp, the setting that is the rectangle the tight pole of screwing on the tight frame of clamp, be equipped with the screw hole on the tight frame of clamp, it is including running through to screw rod, the setting that the screw hole set up are in the tight piece of clamp, the setting of screw rod tip are in locknut, the setting on the screw rod are in the handle of screwing up of another tip of screw rod, press from both sides tight piece setting on the screw rod tip in pressing from both sides tight frame, press from both sides tight piece with locknut sets up respectively press from both sides tight frame both sides. The utility model discloses a bolt tightening device has avoided current spanner commonly used kind many, and work efficiency is low and the high scheduling problem of instrument cost makes manufacturing cost and the processing degree of difficulty greatly reduced, simple structure, convenient operation use the commonality to be higher than special spanner of screwing up.
Description
Technical field
The utility model is related to the devices that various specifications bolt is tightened, more particularly to a kind of fastener for bolt.
Background technology
Currently, every profession and trade not only pursues quality, working efficiency more is being pursued, this requires all kinds of tools outfits of factory are necessary
It is complete.
Existing bolt impact wrench, the type for being often limited to bolt is more, especially same station manipulation when, find spanner
Time it is long, efficiency is very low, and some bolts are when tightening, and bolt can just be tightened by needing to lengthen torque arm.Due to existing
Clamp device not only makes operation difficult, and factory considerably increases the expense that tool is purchased.
Utility model content
The purpose of this utility model is more for existing common spanner type, and working efficiency is low and tool is of high cost etc. asks
Topic, it is proposed that a kind of applied widely, manufacture material is convenient for the fastener for bolt chosen, this fastener for bolt to make to be manufactured into
This and difficulty of processing substantially reduce, simple in structure, easy to operate, and when use is unrestricted, can be suitble to different size bolts, especially
It is to be more suitable for using in the case where spanner is equipped with incomplete.
To achieve the above object, the utility model provides a kind of fastener for bolt, and the fastener for bolt includes
Rectangular clamp frame, the bar of tightening being arranged in the clamp frame, the clamp frame lower frame is equipped with threaded hole, described to twist
Tight bar include through threaded hole setting screw rod, be arranged the screw rod end gripping block, be arranged on the screw rod
Stop nut, handle of tightening in described screw rod the other end, the screw rod end that the gripping block is arranged in clamp frame are set
In portion, the gripping block is separately positioned on the clamp frame both sides with the stop nut.
Preferably, the screw rod is equipped with screw thread, the position that the stop nut passes through the screw rod that is screwed.
Preferably, the clamp frame is formed by the welded steel of high rigidity.
Preferably, the fastener for bolt further includes torque meter.
Based on the above-mentioned technical proposal, the utility model has the advantages that：
It is more that the fastener for bolt of the utility model avoids existing common spanner type, and working efficiency is low and tool cost
The problems such as high, makes manufacturing cost and difficulty of processing substantially reduce, simple in structure, easy to operate, is twisted higher than special using versatility
Spanner etc. is applicable not only to tightening for common bolt, is applied equally to special screw rod, bolt class is tightened.
The fastener for bolt of the utility model makes manufacturing cost and difficulty of processing substantially reduce, simple in structure, operation side
Just, unrestricted when use, different size bolts can be suitble to, especially more applicable in the case where spanner is equipped with incomplete, side
Just quick.
Description of the drawings
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model
It limits.In the accompanying drawings：
Fig. 1 is fastener for bolt structural schematic diagram；
Fig. 2 is fastener for bolt longitudinal direction schematic cross-sectional view.
Specific implementation mode
Below by drawings and examples, the technical solution of the utility model is described in further detail.
The utility model provides a kind of fastener for bolt, as shown in Figure 1 and Figure 2, the utility model is shown
A kind of preferred embodiment.The fastener for bolt can be selected common steel and make, specifically, the fastener for bolt
Including rectangular clamp frame 1, the bar of tightening being arranged in the clamp frame 1,1 lower frame of the clamp frame is equipped with screw thread
Hole, it is described tighten bar include through the threaded hole setting screw rod 4, be arranged 4 end of the screw rod gripping block 3, setting
Stop nut 5 on the screw rod 4 is arranged and tightens handle 6 in 4 the other end of the screw rod, and the setting of the gripping block 3 exists
On 4 end of screw rod in clamp frame 1, the gripping block 3 is separately positioned on 1 both sides of the clamp frame with the stop nut 5.
As shown in Figure 1, fastener for bolt includes clamp frame 1, tightens bar two parts composition.The clamp frame 1 is rectangle
Structure is formed by the good welded steel of hardness, to geometric tolerance without particular/special requirement.The clamp frame 1 is machined with a threaded hole, uses
Bar is tightened in connection.It is described tighten bar by screw rod 4, stop nut 5, gripping block 3, tighten handle 6 and form.
As shown in Fig. 2, the screw rod 4 is equipped with screw thread, the stop nut 5 passes through the screw rod 4 that is screwed
Position, prevent from causing the turn of the screw to be skidded because of loosening when tightening screw.
Preferably, the fastener for bolt further includes torque meter, and by the way that torque meter is arranged, when use can be tightened by bolt
Torque demand is tightened.
The application method of the fastener for bolt of the utility model can refer to following steps：
Tighten preparation：
Fastener for bolt is placed on bolt suitable position to be tightened；Bolt to be tightened is got in place.
Tighten implementation：
A. bolt is directed at workpiece screw hole to be tightened, screws in number button manually；
B. according to nuts size to be tightened, the gap of device for screwing up and nuts is adjusted by screw rod, is inserted in bolt
On cap, the turn present apparatus tightens handle, and fishbolt cap simultaneously tightens stop nut；
C. handle is tightened in rotation, until bolt is tightened.
It is more that the fastener for bolt of the utility model avoids existing common spanner type, and working efficiency is low and tool cost
The problems such as high, makes manufacturing cost and difficulty of processing substantially reduce, simple in structure, easy to operate, is twisted higher than special using versatility
Spanner etc. is applicable not only to tightening for common bolt, is applied equally to special screw rod, bolt class is tightened.
The fastener for bolt of the utility model makes manufacturing cost and difficulty of processing substantially reduce, simple in structure, operation side
Just, unrestricted when use, different size bolts can be suitble to, especially more applicable in the case where spanner is equipped with incomplete, side
Just quick.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
