Description
Technical field
The utility model design high-intensity fasteners manufactures field, is specifically related to a kind of simple and easy nut pre-tightening mechanism.
Background technology
Securing member is fastenedly connected with and applies class machine components very widely.On various machinery, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., securing member miscellaneous can be seen.Its feature is that description is various, and performance purposes is different, and standardization, seriation, unitized kind of degree are also high.Therefore also there is people that one class securing member of obtained official standard is called standard fasteners, or referred to as standard component.Securing member is most widely used mechanical basic part.Join WTO calendar year 2001 along with China and step into the ranks of international trade big country.China's fastener products exports to countries in the world in a large number, the fastener products of countries in the world also constantly pours in Chinese market.Securing member, as one of larger product of China's import & export quantity, realizes in line with international standards, and to promotion, Chinese securing member enterprise goes to the world, and promotes that securing member enterprise participates in international cooperation and competition comprehensively, all tool important realistic meaning and strategic importances.
As stud and nut are last in shipment packaging all need nut to screw on stud, carry out external packing again, at present, way be adopt people screw by hand, following problem can be there is like this: the labour intensity that (1) employing people screws workman is by hand excessive, and the efficiency screwed is low, need the manpower man-hour of at substantial, increase entreprise cost; (2) screw there is randomness, cause the uniformity of product poor; (3) the upper corner angle on bolt easily scratch workman's finger, affect the security of operative.
Utility model content
Adopt artificial pretension efficiency low to solve nut pretension operation, labor strength is large, the problems such as at substantial manpower man-hour, the utility model provides a kind of simple and easy nut pre-tightening mechanism, its simple structure, low cost of manufacture, and the pretension efficiency having increased substantially nut, save manpower man-hour, reduce enterprise's production cost.
A kind of simple and easy nut pre-tightening mechanism, be made up of rotating disk and the claw be arranged on rotating disk, described rotating disk is provided with supporting seat, described claw is hinged on described supporting seat by rotating shaft, and the angle of described adjacent claw centreline space is 120 degree.
Further, described supporting seat is made up of the gripper shoe that two are parallel to each other, and the space between described two gripper shoes forms the rotation space of described claw.
As preferably, described claw is made up of clamping section, fixed part and the portion of pushing against, and described clamping section and the portion that pushes against are connected fixing by fixed part.
Better, one end, described clamping section stretches out formation transition part.
As preferably, described fixed part is provided with a manhole, and described rotating shaft through described through hole, and is hinged on described supporting seat.
Further, the projection of shape of described claw is L-type.
The utility model has the advantage of: the outer face of being blocked nut by claw hinged on rotating disk, simulate the action of manually holding nut, avoid corner angle and cause the scuffing that workman is pointed, make operation safer, secondly, realized the pretension of nut by dial rotation, increase substantially and screwed efficiency, alleviate labor strength, save manpower man-hour, reduce the production cost of enterprise simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of simple and easy nut pre-tightening mechanism;
Fig. 2 is the structural representation of rotating disk;
Fig. 3 is the structural representation of claw.
Detailed description of the invention
The utility model provides a kind of simple and easy nut pre-tightening mechanism, its simple structure, low cost of manufacture, and the pretension efficiency having increased substantially nut, saves manpower man-hour, reduces enterprise's production cost.
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technical scheme in the utility model, obviously, described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of the utility model protection.
Shown in composition graphs 1 to Fig. 3, a kind of simple and easy nut pre-tightening mechanism, be made up of rotating disk 1 and the claw 2 arranged on the turntable 1, described rotating disk 1 is provided with supporting seat 10, described claw 2 is hinged on described supporting seat 10 by rotating shaft 3, the angle of described adjacent claw 2 centreline space is 120 degree, described supporting seat 10 is made up of two gripper shoes be parallel to each other 101, space between described two gripper shoes 101 forms the rotation space 12 of described claw, described claw 2 is by clamping section 21, fixed part 20 and push against portion 23 and form, described clamping section 21 and push against portion 23 and be connected fixing by fixed part 20, one end, described clamping section 21 stretches out and forms transition part 22, be convenient to putting into and clamping of workpiece, described fixed part 20 is provided with a manhole 24, described rotating shaft 3 is through described through hole 24, and be hinged on described supporting seat 10, the projection of shape of described claw 2 is L-type.
Rotating disk 1 is provided with shaft hole 13, rotating disk 1 is generally arranged on turning cylinder 300, when rotating disk 1 rotates, weight due to clamping section 21 is greater than the weight in the portion of pushing against 23, under the influence of centrifugal force, clamping section 21 is outwards thrown away, thus open, therefore, the clamping of the nut of various outer diameter dimensions can be adapted to, when in time pushing against in portion 23 described in screwing nut 100 and being resisted against, due to lever principle, clamping section 21 is inwardly regained, now, three alternate seamed edges of six-sided nut 100 will be clamped in clamping section 21, thus drive nut 100 to rotate, and screw on stud 200, complete pretension process.
The utility model has the advantage of: the outer face of being blocked nut by claw hinged on rotating disk, simulate the action of manually holding nut, avoid corner angle and cause the scuffing that workman is pointed, make operation safer, secondly, realized the pretension of nut by dial rotation, increase substantially and screwed efficiency, alleviate labor strength, save manpower man-hour, reduce the production cost of enterprise simultaneously.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
