Description
Technical field
The invention belongs to fastening apparatus technical fields, and in particular to a kind of clamp device of bolt and nut.
Background technique
Bolt in and in industrial production and manufacturing, be can't do without in daily life, and bolt is also referred to as rice of industry,
It can be seen that bolt is extensive with it.The operation strategies of bolt have: electronic product, engineering goods, digital product, power equipment, machine
Electromechanical product.Ship, vehicle, hydraulic engineering etc., it is main that the various kinds of equipment majority of modern industry, which is all to be bolted,
Connection type has vital relationship whether being bolted with equipment operational safety.It is tight required for bolt specification is bigger
Gu power is bigger, therefore people generally use power tool to the bolt of big specification now and fasten.Common power tool
There are torque stretching-machine and pneumatic tools.And torque stretching-machine is because can pass through hydraulic pump by the output pressure of adjusting hydraulic coupling
Continuous, stable output pressure is provided, requires stringent bolted preferred fastening method to become.Torque stretching-machine
Working principle is generally high pressure or the liquid medium (generally hydraulic oil) of super-pressure pushes the intracorporal piston of torque stretching-machine cylinder
Bar acting, the piston rod of torque stretching-machine connect a ratchet mechanism, and ratchet mechanism passes through the square toes of one standard of spline drived
Drive shaft, the sleeve that square toes drive shaft passes through standard again are connected with hex nut, to realize rotating nut fastening bolt.It turns round
Square stretching-machine is equivalent to external reaction force according to Newton's third law because of the reaction arm of force outside existing at work
Fulcrum generates inverting action to entire torque stretching-machine system by sleeve and nut, makes bolt end by additional offset loading force
Square makes the nuts and bolt thread normally engaged originally generate unbalance loading, so as to cause frictional contact surface variation, makes original face-
Face contact friction is changed into point-face contact or line-face contact friction, and frictional force is caused to change.Since each bolt is tight
Gu when need to adjust the fulcrum of the reaction arm of force to obtain firm external fulcrum, so the branch outside when fastening each bolt
Point is all not quite similar, and the offset loading force that counter-force fulcrum difference causes counter-force fulcrum to generate is different, and then causes each bolt fastening
When need the frictional force that overcomes different, eventually lead to the tools for bolts ' pretension of each bolt after the completion of fastening on the same flange face
Power error is larger.Reaction force fulcrum between the bolt just fastened at a distance from it is shorter, offset loading force is bigger.Existing bolt, nut
The design of spiral is usually utilized, bolt returns pine in order to prevent, also frequently it is applied in combination using the mode of check washer or nut,
In its use process, needs manually to rotate repeatedly, nut is first installed to suitable position, then re-tightens bolt, using not
Just, but also working hour is expended, there are some electric tools that can tighten bolt by motor drive in the market, but it can only be right
Bolt is tightened, and for nut of the pad inside bolt but since structure limitation can not tighten, still can not be got rid of artificial
The limitation of operation.In the installation process of fastener, because staff can only fasten one in bolt or nut
Operation, if the nut or bolt of the other end cannot get the fixation of slot position, nut or bolt, which are easy to be acted on by frictional force, to be occurred
With phenomenon is turned, need that manually the nut of reverse side or bolt is fixed so that it will not rotate, it is single especially for larger object
People is even more that can not fasten to it, and efficiency is had a greatly reduced quality, although nowadays there are various bolt clamp devices, is provided with spiral shell
Female and bolt sleeve, can be by fixing nut, and rotation bolt reaches fastening effect, but for biggish mounting surface device
It can not work at all across both sides, so being badly in need of a kind of bolt and nut clamp device for this environment.
Summary of the invention
The technical problems to be solved by the invention: transfer is easy for bolt and nut when fastening at present for fixing piece
