Abstract
The utility model discloses a kind of anti-loosing nut components, including stop nut (1), fastening bolt (3) and fastening nut (2), the stop nut (1) is divided into up-small and down-big two parts, slot, which is separated, on the top of stop nut (1) is divided into both sides, and it is provided with the bolt through-hole through both sides, one group of fastening bolt (3) and fastening nut (2) are equipped on bolt through-hole.The nut assembly of the utility model limits installation site by stop nut, and the both sides of stop nut are shunk by tightening fastening bolt, realizes the holding of stop nut, and realization is anti-loose, and workpiece is avoided to have leakage to clamp hidden danger.
Description
Technical field
The utility model relates to fastening connection piece technical field, specifically a kind of anti-loosing nut component.
Background technique
The step of boring machine clamping cylinder body is as follows at present: cylinder block top surface is placed in tooling upward, and two gripping blocks are certainly
It is dynamic to extend into top face from rear and front end respectively, a fixed link is passed through among gripping block, and spring is installed below gripping block
(covering in fixed link) jacks up gripping block from lower to upper, has stop nut (to be connected through a screw thread, be mounted on above gripping block
In fixed link).Hydraulic cylinder jacks up gripping block from outside by skewback, and gripping block is using stop nut as fulcrum, and the other end is down
Compression cylinder body top surface.
Existing stop nut is made of two plain nuts, after being adjusted to suitable position, is fixed with spanner following
Nut, nut above are held out against down again, and two nut frictionallies are mutually locked.The stop nut of this structure was using
Cheng Zhong is easy to happen rotation and loosens, and workpiece is caused to have leakage to clamp hidden danger.
The disclosure of background above technology contents is only used for the design and technical solution that auxiliary understands the utility model, not
The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof
In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
Utility model content
The utility model is easy the defect loosened for existing stop nut, provides a kind of anti-loosing nut component, described
Nut assembly includes stop nut, fastening bolt and fastening nut, and wherein stop nut has enclasping force big, is not easy to loosen, and is tied
The advantages that structure is simple.
The utility model is achieved through the following technical solutions:
A kind of anti-loosing nut component, the nut assembly include stop nut, fastening bolt and fastening nut, the limit
Position nut is divided into up-small and down-big two parts, separates slot on the top of stop nut and is divided into both sides, and is provided with the bolt through both sides
Via hole is equipped with one group of fastening bolt and fastening nut on bolt through-hole.
Further, the fastening bolt side opposite with fastening nut is additionally provided with the gasket being close to stop nut.
Further, the gasket is stainless steel gasket or rubber sheet gasket.
Further, the fluting on the stop nut is U-shaped structure.
Further, the screw rod of the fastening bolt is cored screw.
Compared with prior art, it the advantages of the utility model and has the beneficial effect that
1, the utility model limits installation site by stop nut, shrink stop nut by tightening fastening bolt two
The holding of stop nut is realized on side, and realization is anti-loose, and workpiece is avoided to have leakage to clamp hidden danger.
2, the utility model has the advantages of simple structure, practical, easy to operate, has a good application prospect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model anti-loosing nut component；
Fig. 2 is application of the anti-loosing nut component in boring machine clamping cylinder body.
Attached drawing mark: 1- location nut, 2- fastening nut, 3- fastening bolt, 4- gasket, 5- gripping block, 6- cylinder block,
7- tool pedestal, 8- hydraulic cylinder, 9- bracket, 10- fixed link.
Specific embodiment
With reference to embodiment and control attached drawing is described in further detail the utility model.It should be emphasized that
It is that following the description is only exemplary, rather than in order to limit the scope of the utility model and its application.
Embodiment 1
As shown in Fig. 1, nut assembly described in the utility model includes stop nut 1, fastening bolt 3 and fastening nut
2, the stop nut 1 divides for up-small and down-big two parts, separates slot on the top of stop nut 1 and is divided into both sides, and is provided with and runs through
The bolt through-hole on both sides is equipped with one group of fastening bolt 3 and fastening nut 2 on bolt through-hole.The fastening bolt 3 and fastening spiral shell
Female 2 opposite sides are additionally provided with the gasket 4 being close to stop nut 1.Fluting on the stop nut 1 is U-shaped structure.It is described
The screw rod of fastening bolt 3 is cored screw.
As shown in Fig. 2, in the application of boring machine clamping cylinder body, hydraulic cylinder 8 is in when use shrinks the nut assembly
State, gripping block 5 do not clamp, unclamp fastening nut 5, and adjustment stop nut 1 observes 5 phase of gripping block in the position of fixed link 10
The height in face is clamped to cylinder block 6, then control height fixes fastening bolt 3 with spanner, on another spanner in 2-4mm
Tight fastening nut 2,1 both sides of stop nut of fluting will clamp, and flexible deformation has occurred, and hold tightly in fixed link 10, adjustment
It completes.When 5 clamped condition of gripping block, hydraulic cylinder 8, which swells, pushes bracket 9 to travel forward, bracket 9 push the left side of gripping block 5 to
Upper right side movement, gripping block 5 are fulcrum with stop nut 1, right side compression cylinder body 6 to the right.Stop nut 1 plays
Limit 5 height of gripping block and the effect as 5 fulcrum force of gripping block.
The above content is combining specific/preferred embodiment further detailed description of the utility model,
It cannot be assumed that the specific implementation of the utility model is only limited to these instructions.For the common of the utility model technical field
For technical staff, without departing from the concept of the premise utility, the embodiment that these have been described can also be made
Some replacements or modifications, and these substitutions or variant all shall be regarded as belonging to the protection scope of the utility model.
