Abstract
The utility model provides a sleeve for automatically marking a screw thread member, consisting of three major parts: a square connecting head, a sleeve rod and a sleeve head. A dye cavity is opened in the sleeve rod and the cavity is filled with dye, and a compression spring at the upper end of the cavity puts a pre-compression on the dye through a piston. A valve is arranged between the outlet pipe of the dye cavity and the sleeve head and is normally shut down. When being tightened, the sleeve head can rotate in a certain degree relatively to the sleeve rod, and the rotation of a core rod can be driven by a vertical driving effect from a bevel gear and a gear rack to cause the valve to open, then the dye spouts out onto the screw thread member. After being tightened, the sleeve head and the sleeve rod rotate back under the action of a torsional spring, and the core rod revert to the original position, causing the valve to close. The sleeve has the advantages that the dye reserved in the sleeve can automatically spout out to automatically mark the screw thread member when the screw thread member is tightened and the automatic marking is accomplished after the tightening is completed, and that not only the purpose of marking to prevent tightening miss is achieved, but also the normal production efficiency is not affected.
Description
Technical field
The utility model relates to a kind of sleeve that can do sign automatically, particularly can double thread spare in the rundown process of securing members such as bolt, nut makees the sleeve of sign automatically.
Technical background
In machinery manufacturing industry, thread connection is the most frequently used connecting mode, and the most frequently used fastening method of screw element is to use the various spanners of band sleeve to tighten.In high volume production process, as engine in batches in the assembling process, often have a large amount of screw elements to tighten with autowrench such as pneumatic, electronic after, also need the workman to tighten up moment with manual torque spanner.Tighten for preventing that screw element from leaking, means commonly used are to identify with a dyestuff double thread spare after step is finished in all tightening again.This manual method that identifies with the dyestuff pen has following limitation: on the one hand, for reaching best leak preventing effect, need whenever finish tightening of a screw element and promptly carry out Manual Logos one time, the same workman of same operation is in carrying out the batch rundown process, the method operation of this Manual Logos is complicated, will reduce production efficiency greatly; On the other hand, unifiedly again after the tightening of a collection of screw element carry out Manual Logos if finish, though efficient increases, leak preventing effect is not satisfactory.
Summary of the invention
The purpose of this utility model is to provide a kind of and solves above-mentioned leakproof and twist contradiction with production efficiency, promptly identify by hand and tighten and to carry out simultaneously, in the process that tightens up screw element with manual torque spanner, carry out Automatic Logos by being stored in the automatic ejection of dyestuff in the sleeve, tighten and finish, it is simple in structure that sign is promptly finished, and is easy to install, be convenient to safeguard, cost is low, and dyestuff can be filled, and the double thread spare of Automatic Logos is made the sleeve of sign automatically.
Technical solution of the present utility model is such: sleeve mainly is made up of collet head three parts of the square toes that connect spanner, socket bar, connecting thread spare; Have the dyestuff chamber in the socket bar, be full of dyestuff in the chamber, the compression spring on its top applies certain precompression by piston to dyestuff; A valve is arranged between dyestuff chamber outlet and the collet head, close under the normality; During the threaded together part, collet head can rotate relative to socket bar, and turns over certain angle by circular cone tooth bar, gear driven core bar around self axis, makes valve opening, dyestuff just under the precompression effect by valve, nozzle, be sprayed onto on the screw element; Tighten finish after, rotate at the effect lower sleeve head of torsionspring and socket bar, drive core bar and go back to original position, make valve closing; Thereby finish Automatic Logos.
Comprise and connect square toes, socket bar, collet head, conical gear, circular cone tooth bar, core bar, compression spring, torsionspring, piston, locking nut, it is characterized in that connecting square toes branch sleeve bar, socket bar branch sleeve head, the dyestuff chamber is arranged in the middle of the socket bar, top, dyestuff chamber is a piston, it above the piston compression spring, be connected with collet head below the socket bar, torsionspring, locking nut, circular cone tooth bar are arranged in the collet head, core bar is housed at the bottom of the socket bar, dyestuff is communicated with discharge opening under the chamber, and the end of discharge opening is a nozzle.
Socket bar be connected square toes and connect, the small end end face of square toes is to there being the compression spring between the piston, there is dyestuff in the dyestuff chamber under the piston, and the valve gauge tap is arranged between discharge opening and the nozzle.
Socket bar small end cylindrical is to torsionspring (10) being arranged, conical gear and the engagement of circular cone tooth bar between the collet head internal orifice dimension.
The utility model has the advantages that:
1, when tightening, finish the Automatic Logos that leakproof is twisted, simple to operation, improved production efficiency greatly.
2, simple in structure, be easy to install, be convenient to safeguard that cost is not high.
3, can refill after dyestuff uses up, so the Automatic Logos sleeve can reuse.
4, consumable accessory (as collet head) is conveniently replaced, is beneficial to the utilization rate that improves miscellaneous part.
Description of drawings
It is such that structure of the present utility model constitutes
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among Fig. 1-Fig. 2, connect square toes (1), socket bar (2), collet head (3), conical gear (4), circular cone tooth bar (5), nozzle (6), locking nut (7), core bar (8), valve (9), torsionspring (10), discharge opening (11), dyestuff chamber (12), piston (13), compression spring (14).
The specific embodiment
Most preferred embodiment of the present utility model is such, and with reference to Fig. 1-Fig. 2, the upper end square toes that connect square toes (1) are connected with spanner, and the small end cylindrical of lower end square toes has a screw, can be connected and fixed by screw or pin and socket bar (2).Have dyestuff chamber (12) in the socket bar (2), fill dyestuff in the chamber after, compression spring (14) is compressed connecting under square toes (1) and piston (13) spacing, thereby imposes on precompression of dyestuff.Dyestuff outlet on small through hole on the core bar (8) and the socket bar (2) is in same plane, constitutes valve (9) jointly.Conical gear (4) is made of one with core bar (8), and core bar (8) inserts in the following stomidium of socket bar (2), and circular cone tooth bar (5) is fixed on collet head (3) base, and collet head (3) has a breach to be installed in conical gear (4), circular cone tooth bar (5).When collet head (3) and socket bar (2) when relatively rotating, core bar (8) the just vertical gearing by circular cone rack pinion (5,4) rotates along self axis, makes valve (9) open or close.Socket bar (2) is adorned locking nut (7) between the collet head (3), and locking nut (7) makes collet head (3) can not deviate from socket bar (2).
2 as seen in conjunction with the accompanying drawings, and collet head (3) can relatively rotate an angle [alpha] with socket bar (2).Torsionspring (10) two ends up and down inserts socket bar (2) and collet head (3) respectively.Under the original state, torsionspring (10) makes socket bar (2) counterclockwise by upper bush head (3), at this moment valve closing; Under the tight condition, the effect that the torsion of spanner overcomes torsionspring (10) makes socket bar (2) turn over the α angle clockwise, and conical gear (4) drives core bar (8) rotation with circular cone tooth bar (5) simultaneously, and valve this moment (9) is opened, the dyestuff ejection; Tighten finish after, get back to initial position at effect lower sleeve bar (2), collet head (3), the core bar (8) of torsionspring (10), valve (9) is closed, and finishes Automatic Logos.
