Description
Technical field
The present invention relates to technical field of fastening, especially a kind of bolt retainer and method for locking.
Background technique
Bolt is a kind of common machanical fastener, is made of head and screw rod two parts, is widely used in machinery and sets
The every field such as standby, engineering construction.It is generally bolted and is able to satisfy condition of self-locking without loosening automatically, but in shock and vibration
Or when running under varying load effect and under high temperature environment, the bolt being mounted on mechanical equipment is easy to happen loosening, even
It falls off, directly affects the behavior in service of mechanical equipment, security reliability reduces.Bolt looseness is because opposite between screw thread pair
Caused by rotation, using bolt more effective long-term work when locking measures energy appropriate, the reliability of connection is improved.It is most common
Detachable screw retention be addition gasket to increase frictional force, or locking guarantee to prevent using the mechanical of retainer
Pine.Mechanical locking locking more reliable relative to rubbing, still, existing bolt retainer requires to change the knot of bolt itself
Structure, for example aperture or groove prevent from loosening on bolt to be inserted into retainer.This bolt retainer has the following deficiencies: 1,
It is only capable of mechanical stop, stop is in the form of a single, and screw retention is ineffective；It is not available in plain bolt；2, retainer is located at machine
Inside tool equipment, and only it is lesser can operating space or when can not view interspersed hole location, inconvenient, installation is more tired
It is difficult.
Summary of the invention
The object of the present invention is to provide a kind of bolt retainer and method for locking, this retainer and method for locking can be solved
Certainly existing bolt retainer has that screw retention is ineffective.
To solve the above-mentioned problems, the technical solution adopted by the present invention is that: this bolt retainer, including offer bolt
The locked spacer in hole, is also provided on the locked spacer and is inserted in one jiao of bolt head of stop hole, and the stop hole is located at institute
It states on bolt hole and the locked spacer between the gasket corner of the bolt hole, the gasket corner is pressed on the spiral shell
The hole edge of bolt head upper surface, the stop hole is close to the bolt head.
In the technical solution of above-mentioned bolt retainer, more specific technical solution may also is that be set on the locked spacer
It is equipped with the gasket corner, the stop hole and the bolt hole of multiple groups pairing.
Bolt method for locking of the invention the following steps are included:
A, the position of multiple bolts of stop as needed prepares a locked spacer, according to each bolt on locked spacer
Distance and bolt size drill bolt hole；
B, stop hole is bored in the position on locked spacer between the gasket corner of bolt hole；
C, locked spacer is placed in mounting outer surface, pacifies each bolt hole of locked spacer and the bolt in mounting
Hole alignment is filled, bolt is then loaded onto and tightens, be clamped in locked spacer between mounting and bolt head；
D, it will be rolled on the gasket corner of bolt on locked spacer, one jiao of bolt head be inserted in stop hole, stop hole is made
Hole edge be close to bolt head, then depress gasket corner, gasket corner made to be pressed in the upper surface of bolt head；
E, the stop of remaining bolt on locked spacer is completed by step D.
Further, the center of the stop hole is at the corresponding endpoint of the gasket corner and the center of the bolt hole
Line on.
Further, the stop hole and the spacing of the bolt hole are 2mm or more.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
1, bolt hole and stop hole are opened up on the locked spacer with corner, can be entangled firm by stop hole across bolt hole
One angle of bolt head, while gasket corner can be pressed in bolt head upper surface and realize stop, so that friction immobilisation and machinery stop
It is dynamic to combine, effectively improve screw retention effect.
2, bolt hole, stop hole and gasket corner that multiple groups are matched are set on locked spacer, multiple stop points can be passed through
Mutual limitation, the reliability of stop is further increased, to obtain more preferably screw retention effect.
3, stop hole is centrally disposed on the gasket corner endpoint and bolt hole center's line with group, bolt head can be made
One angle is easier to be inserted in stop hole, while bolt head being made to be tightly attached to the opposite sides of hole edge, uniform force.
4, the spacing of bolt hole and stop hole is located at 2mm or more, can effectively avoid compartment fracture, it is ensured that screw retention
Effect.
5, stopper structure form of the invention is simple and practical, easy to operate, easily checks, at low cost；Its mounting means and make
It is saved labor the most with form, can fasten and may be reused over a long time after hole shape locked spacer installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of bolt retainer embodiment.
Fig. 2 is the original state signal that bolt retainer installs bolt.
Fig. 3 is the status diagram that bolt retainer installs completion stop after bolt.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings:
Fig. 1 to bolt retainer shown in Fig. 2 include the locked spacer 1 equipped with bolt hole 2 and stop hole 3, wherein bolt hole 2
For installing bolt, stop hole 3 is for entangling bolt head 5 firm.The locked spacer 1 of the present embodiment is the length for four bolts of stop
Square washer is opened up on two diagonal intersecting lenses of locked spacer 1 there are four bolt hole 2 and four stop holes 3, stop hole 3
On bolt hole 2 and locked spacer 1 between the gasket corner 4 of the bolt hole 2, the center of stop hole 3 is padded accordingly
On the line at the center of the endpoint and bolt hole 2 of piece corner 4, the spacing of stop hole 3 and bolt hole 2 is 2mm or more.Such as Fig. 3 institute
Show, after gasket corner 4 is folded upward at, so that the hole edge of stop hole 3 is close to bolt head 5, gasket corner 4 is pressed on bolt head 5
End face, can 5 angles of locking bolt head, realize stop.
The method for locking for four hex bolts of oil cap that the present embodiment is used to fix in sintering pallet wheel include with
Lower step:
A, rectangular locked spacer is prepared according to the position for four bolts for needing stop on oil cap, on locked spacer
According to the distance and bolt size drill bolt hole of each bolt；
B, stop hole, stop hole and bolt hole are bored in the position on locked spacer between the gasket corner of each bolt hole respectively
Spacing be 2mm；
C, locked spacer is placed in oil cap outer surface, each bolt hole and the bolt mounting holes pair on oil cap for making locked spacer
Together, it then loads onto bolt to tighten, is clamped in locked spacer between oil cap and bolt head；
D, it will be rolled on gasket one of on locked spacer corner, be inserted in one jiao of the bolt head close to the gasket corner accordingly
Stop hole in, which exposes from stop hole, and hole edge is close to hex bolts two sides, then depresses gasket corner, makes gasket side
Angle is pressed in the upper surface of bolt head, in this way, one jiao of hexagon bolt head is stopped hole latching, reaching prevents bolt looseness
Purpose；
E, by step D successively on roll over and push its excess-three gasket corner, complete the stop of remaining three bolts on locked spacer.
The present invention is in Liu Gang sintering plant 110m2It installs and comes into operation on the gland of sintering pallet wheel, and take
Obtained good effect.It is easily loosened using gland bolt before the present invention, is not easy to loosen using rear bolt.
