Description

A kind of sleeve for putting paint mistake proofing
Technical field
It the utility model is related to engine dress examination technical field, and in particular to a kind of sleeve for putting paint mistake proofing.
Background technology
When assembling all kinds of bolts of engine, in order to ensure the reliability of engine, require first to use bolt in technique After spanner is tightened, then bolted on torque with torque spanner.But after being tightened due to bolt, it is impossible to tell from the appearance whether on Moment, the failure that torque is twisted so as to bolt leakage happen occasionally, and thus bolt looseness can be caused to come off, the consequences such as part flies out, Cause personal injury.Therefore, the method that currently can only put paint on the bolt after make-up torque with paint dotting pen, can confirm that big portion It is upper moment to divide engine bolt, but because of carelessness of operator, it may appear that on the bolt of no make-up torque The mistake of point paint, bolt leakage upper torque in part is so also caused to obtain situation, in summary, it is necessary to design when assembling bolt A kind of instrument that can absolutely ensure to cross torque on bolt.
The disclosure of background above technology contents is only used for auxiliary and understands design of the present utility model and technical scheme, and it is not The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application in no tangible proof In the case of disclosed, above-mentioned background technology should not be taken to evaluate the novelty and creativeness of the application.
Utility model content
The utility model is for above-mentioned technical problem offer one kind is simple in construction, production cost is low, is carrying out make-up torque When can mark automatically, point paint error proof sleeve easy to use.
To achieve the above object, the utility model adopts the following technical scheme that:
A kind of sleeve for putting paint mistake proofing, including sleeve, paint dotting pen;The sleeve upper end offers wrench square head groove, is used for It is connected with wrench square head, its lower end offers bolt head groove, offers inner chamber inside it;The paint dotting pen is distributed in In the inner chamber of the sleeve, and paint dotting pen nib can extend the bolt head groove upper end.
Further, in addition to any paints pen cap and a spring;The paint dotting pen set is engaged with the paint dotting pen, is used for Entangle the fixed paint dotting pen;The spring is distributed in the paint dotting pen set top, and the paint dotting pen set is pressed down against, and protects Demonstrate,proving the paint dotting pen can stretch up and down.
Further, the inner chamber of the sleeve communicates with wrench square head groove, and the inner chamber upper end is further opened with circlip groove.
Further, in addition to a back-up ring, the back-up ring match the circlip groove, are distributed in circlip groove, are mainly used in Blocking spring and paint dotting pen set prevents prolapse upwards.
Further, in addition to a spring-support plate, the spring-support plate are distributed in below the back-up ring and the bullet Above spring.
Further, barrier plate is provided with above the bolt head groove, circular hole, the circular hole is offered among the barrier plate It is engaged with the paint dotting pen nib, the stop version is mainly used in preventing paint dotting pen from dropping from lower section.
The beneficial effect of the utility model compared with prior art:The utility model provided with sleeve, upper cartridge by setting There is wrench square head groove, realization is connected with wrench square head, and lower cartridge is provided with bolt head groove, is distributed in sleeve and paints a little Pen, paint dotting pen set and spring, by the automatic telescopic of paint dotting pen, when carrying out make-up torque, realize to bolt head from dynamic point Paint, and paint dotting pen energy automatic telescopic is advantageous to protect paint dotting pen from the damage of pressure, and by can be with provided with paint dotting pen set The replacing of paint dotting pen is realized, and replacement operation is easy.The utility model is simple in construction, production cost is low, effect easy to use is good.
Brief description of the drawings
Fig. 1 is the structural representation of sleeve part of the present utility model;
Fig. 2 is overall structure diagram of the present utility model;
Fig. 3 is upward view of the present utility model;
Fig. 4 is the structural representation of back-up ring of the present utility model.
Embodiment
As shown in figures 1-4, a kind of sleeve for putting paint mistake proofing, including sleeve 1, paint dotting pen 5, paint dotting pen set 4, spring supporting The spring 3 of plate 7 and one;The upper end of sleeve 1 offers wrench square head groove 10, for being connected with wrench square head, with logical Cross spanner and carry out operation.The lower end of sleeve 1 is further opened with bolt head groove 11 simultaneously;The inside of sleeve 1 offers inner chamber 6, described interior Chamber 6 communicates with wrench square head groove 10;The paint dotting pen 5 is distributed in paint dotting pen set 4, and the paint dotting pen set 4 is distributed in the set In the inner chamber 6 of cylinder 1, the upper end of the paint dotting pen set is withstood in the lower end of spring 3, and the spring supporting is withstood in the upper end of spring 3 Plate 7;Meanwhile in order to block the spring-support plate 7 on top, its prolapse upwards is prevented, offer gear in the upper end of inner chamber 6 Ring recess 8, and back-up ring 2 is correspondingly provided with, by the way that the back-up ring 2 is inserted in circlip groove 8, stop is played to the spring-support plate 7 Effect, and then ensure that the paint dotting pen set 4 and paint dotting pen 5 can realize elastic telescopic up and down.To prevent and treat the paint dotting pen 5 described in The lower end of sleeve 1 is dropped, and barrier plate 9 is additionally provided with above the bolt head groove 11, and the middle part of barrier plate 9 offers an aperture, The aperture is engaged with the nib of paint dotting pen 5, and the nib of paint dotting pen 5 can extend out to the bolt head groove by the aperture In 11, it is ensured that after the bolt head groove 11 is inserted in bolt head, the nib of paint dotting pen 5 can be to bolt head point paint.
When in use, first wrench square head groove 10 of the present utility model is connected with wrench square head, then by by bolt head Groove 11 is pressed into the bolt head for treating make-up torque, and then paint dotting pen 5 is bolted a upward while bolt head also by paint dotting pen 5 Nib point paint, deviate from bolt head after, paint dotting pen 5 in the presence of spring 3 again be forced out, continue repeat torque tighten and put paint make Industry, that realizes high accuracy tightens a paint mark;When needing change paint dotting pen 5, by dismantling back-up ring 2, re-replace Paint dotting pen 5 in paint dotting pen set 4, simple to operate, easy to use, the utility model is not only simple in structure, and production cost Low, using effect is good.
