Abstract
The utility model relates to a connection fastener, in particular to a thread fastening cone pin axle, which consists of a cone pin axle and a lock nut. A small end of the cone pin axle is provided with an external thread and an empty cavity is provided at one side of the holddown end face of the lock nut. When the connection is executed, the cone surface of the small end of the cone pin axle is extended out of a cone hole of a connected element and is in the empty cavity of the lock nut and the lock nut is cooperated with the external thread of the small end of the cone pin axle. A big end of the cone pin axle is provided with a shoulder and the small end is provided with a stepped shaft. Because the structure in which the cone pin axle is cooperated tightly with the cone hole of the connected element under the action of the winding-up force of the lock nut to fixedly connect the connected element and the load is passed through using the working surface of the cone is adopted, the utility model has advantages of high positioning precision, uniform stress, large bearing and high integral rigidity and stability of the connected element and in particular is suitable for larger scale structure elements connected in the harsh environment of impact and vibration.
Description
Technical field
The utility model relates to the connection fastening piece, and particularly a kind of screw threads for fastening circular cone bearing pin is applicable to connection between two or more metallic material or the nonmetallic material, accurate location and fastening.
Background technique
The relative position that taper pin is mainly used between the retaining element plays the role of positioning, and also can be used as to connect the fastening piece transferring power.The advantage of taper pin is owing to be the cone match transferring power, so Location accuracy is than straight pin height, can self-locking when being subjected to transverse force, can be used for the often occasion of dismounting, and its shortcoming is that fastening effect is not strong, transmitted load is little.Cylindrical pin can adopt screw thread or cotter pin locking as connecting fastening piece, and fastening effect is stronger, and convenient disassembly is generally used for the hinged place, and its shortcoming is that the quality of fit of joint is not high, can not be used to have the connection of impact, vibration.Based on above-mentioned taper pin, cylindrical pin merits and demerits are analyzed, the connection request Location accuracy higher, stressed big, connect under whole rigidity and the stable higher situation, taper pin, cylindrical pin are subjected to respective limits as the application of coupling.Therefore need the fastening circular cone bearing pin of a kind of connection fastener threads of design in conjunction with taper pin and cylindrical pin common advantage.
Summary of the invention
The purpose of this utility model provides a kind of Location accuracy height that has, and stressedly evenly carries greatlyyer, and satisfies connected piece integral rigidity and the high screw threads for fastening circular cone bearing pin of stability requirement.
The utility model is made of circular cone bearing pin, locking nut, circular cone bearing pin small end has outside thread, end face one side that compresses of locking nut has a cavity, the circular cone bearing pin small end conical surface stretches out the connected piece taper hole and is positioned at the cavity of locking nut during connection, and locking nut cooperates with the outside thread of circular cone bearing pin small end.
The big end of above-mentioned circular cone bearing pin also has a shoulder.
The small end of above-mentioned circular cone bearing pin also has a multidiameter shaft.
Working principle: the circular cone bearing pin screws locking nut after penetrating the conical bore of connected piece, makes the end face that compresses of locking nut compress link, and keeps certain force value, prevents thread looseness.The circular cone bearing pin is that conical surface cooperates with connected piece, under the effect of locking nut pressure, the cone surface of bit axle, the hole is engaged in axle on the force action line vertical plane, the hole contact form is whole face contact, the circular cone bearing pin produces certain compressive plastic deformation and resiliently deformable on the loading direction outside and also produce resiliently deformable and plastic deformation on the Vertical direction of external load, working surface to conical bore produces active force, thereby make whole cone surface of bit all be in stress, stress surface accounts for the ratio of entire working surface near 100%, thereby the circular cone bearing pin is stressed evenly, and anti-extrusion ability obviously improves.The design of locking nut internal cavities makes the circular cone bearing pin small end conical surface extended to taper hole and be positioned at the locking nut cavity, thereby increases the area of contact of circular cone bearing pin and taper hole as much as possible and then increase bearing capacity.The shoulder of the big end of circular cone bearing pin and the multidiameter shaft of small end knock the place when being used for installation and removal circular cone bearing pin, damage cone surface of bit and screw thread working surface when avoiding installation and removal circular cone bearing pin.
The circular cone bearing pin cooperates the structure of connected piece being carried out fastening connection with the connected piece taper hole to the utility model under the power effect because employing screws at nut, make the suffered external force of connected piece pass to the circular cone bearing pin by cone surface of bit, thereby make screw threads for fastening circular cone bearing pin have the Location accuracy height, stressed even, carrying is big, connected piece integral rigidity and the high advantage of stability, particularly suitable connects the relatively large structural member that is in rugged environment such as impact, vibration.

Embodiment
Be the example that the utility model screw threads for fastening circular cone bearing pin is used as shown in Figure 1, stage body 3 and base 4 that truck-mounted drill rig revolves the lift-type rig floor connect by screw threads for fastening circular cone bearing pin, circular cone bearing pin 1 penetrates the taper hole of stage body 3 and base 4, locking nut 2 cooperates with circular cone bearing pin 1 small end screw thread 1-1, the circular cone bearing pin 1 small end conical surface stretches out taper hole and is positioned at the cavity 2-1 that locking nut 2 compresses end face one side, can make the taper hole comprehensive engagement of the conical surface and the stage body 3 and the base 4 of circular cone bearing pin 1.Screw locking nut 2 and make it compress end face to compress stage body 3 and keep certain pressure, thereby make stage body 3, base 4 pass to the suffered load of circular cone bearing pin, make the circular cone bearing pin stressed evenly by the conical bore working surface that cooperates with circular cone bearing pin 1.The shoulder 1-2 of circular cone bearing pin 1 big end and small end multidiameter shaft 1-3 knock the place when being used to install and remove circular cone bearing pin 1, damage conical surface and screw thread when avoiding installing and removing circular cone bearing pin 1.With respect to the cylinder axis of cone, therefore the utility model connects accurate positioning owing to have taper pin; With respect to taper pin make circular cone fitting surface transfer motion power owing to adopt nut to screw to cooperate with screw thread, therefore have stressed evenly, bearing capacity greatly, connected piece integral rigidity and stable high advantage.
