Abstract
A kind of fixture for preventing link bolt from rotating, belongs to mechanical mechanism design field.Including bolt buckle 1, the first screw 2, the second screw 3.Bolt buckle is provided with centre bore, and center hole shape is consistent with the shape of anchor stud head, and there are two flange on periphery, and screw hole is provided with flange.The center hole shape of bolt buckle is consistent with the shape (hex bolts or many corner bolts) of anchor stud head, and the size in hole will can be such that bolt buckle is easily enclosed within bolt head, and gap between the two is not larger than 0.3mm.Two flange of bolt buckle are used for being stuck on rocking arm, and the design of flange will suit with rocking arm, and screw hole is provided with flange, and can be stuck in bolt buckle on rocking arm by screw.The present invention solves service life and not easy-to-dismount problem that link bolt arbitrarily rotates influence bolt by simple and mechanical mechanism, and the maintainability for improving mechanical part and the service life for extending bolt reduce use cost.
Description
Technical field
The invention belongs to mechanical mechanism design field, it is related to a kind of fixture for preventing link bolt from rotating.
Background technology
Link bolt is the crucial part of a comparing in the system of mechanical mechanism, is that mechanical system joint part can not
The setting for lacking.It is typically used cooperatively with rocking arm and pull bar, and rocking arm and pull bar are linked together, realize rocking arm and pull bar it
Between rotary motion.Link bolt is primarily subjected to the shearing force produced between rocking arm and pull bar, and the shearing force of big load can make spiral shell
Bolt flexural deformation, along with the swing of rocking arm, bolt will produce relative movement with rocking arm, this movement to bolt and rocking arm all
It is harmful, in order to eliminate this movement, it is necessary to bolt is fixed together with rocking arm.The present invention has this function
Fixture.
The content of the invention
The purpose of the present invention is：A kind of fixture is designed, the link of rocking arm and pull bar hinged place is bolted on rocking arm,
Prevent from producing rotation between bolt and rocking arm, bolt and rocking arm are shielded.
The technical scheme is that：A kind of fixture for preventing link bolt from rotating, including bolt buckle (1), the first screw
(2), the second screw (3), wherein, bolt buckle (1) is provided with centre bore, and center hole shape is consistent with the shape of anchor stud head, and two
Gap between person is not more than 0.3mm, and bolt buckle (1) periphery is provided with two flange, and flange suits with rocking arm, is set on flange
There is screw hole, bolt buckle (1) is fixed on rocking arm by the first screw (2) and the second screw (3).The first described screw
(2) and the second screw (3) and screw hole between using gluing or spring washer it is locking, it is also possible to beat safety plug.
Beneficial effect produced by the present invention：Link bolt is solved by simple and mechanical mechanism and arbitrarily rotates influence bolt
Service life and not easy-to-dismount problem, the maintainability for improving mechanical part and the service life for extending bolt are reduced
Use cost.
Brief description of the drawings
Fig. 1 is the assembling schematic diagram of the fixture that the present invention prevents link bolt rotation；
Fig. 2 is the part schematic diagram of the fixture that the present invention prevents link bolt rotation；Wherein, 1- bolt buckles, 2- screws, 3-
Screw.
Specific embodiment
The present invention is described in further detail with reference to Figure of description.
As shown in figure 1,
A kind of fixture for preventing link bolt from rotating, including a bolt buckle 1, two screw the first screws 2, the second screws
3 compositions.It is characterized by：
The center of bolt buckle is sky, and (hex bolts is more with the shape of anchor stud head for the center hole shape of bolt buckle
Corner bolt) it is consistent, the size in hole will can be such that bolt buckle is easily enclosed within bolt head, and gap between the two is not larger than 0.3mm.
There are two flange on periphery, and flange is wanted can be tangent with rocking arm, and screw hole is provided with flange.The effect of screw is to be stuck in bolt buckle
On rocking arm, it is not allowed to fall down.
The course of work of the invention is as follows：
A kind of fixture for preventing link bolt from rotating, including a bolt buckle 1, two screw the first screws 2, the second screws
3 compositions.Bolt buckle is enclosed within the bolt head of fixing bolt, flange is stuck on rocking arm, bolt buckle is fixed on rocking arm with screw
On.Link bolt will be unable to rotate in the presence of bolt buckle relative to rocking arm, reach the effect for preventing link bolt from rotating.
Such as above-mentioned specific embodiment, the link bolt for solving the problems, such as mechanical part of the invention arbitrarily rotation.
Claims (2)
