Description

A kind of connection fastener
Technical field
The utility model belongs to field of machining, especially a kind of to fix for metal parts processing NC milling Connection fastener.
Technical background
Connection and clamp device, when one kind it is all extremely common in all trades and professions, with extensive a kind of device, act on It connects and tightens up in by two different components, meet certain intensity and reliability requirement, and then realize certain function Energy.In NC milling field, for the processing for realizing part, it usually needs will be to be added with attachment device using certain fastening The tooling of chemical product and certain shapes is fixed, and removes connection fastener after completing the process.Screw is connected due to it Convenience has obtained extensive utilization, but due to dismounting frequent, process vibration greatly, the reliability fluctuation of connection is larger, by Quality problems happen occasionally caused by fastening failure.
When two different components are connected using screw with fastening, if not by screw-driving to certain thread depth, it will It will appear and connect unreliable, the problem of stability difference.For example, in NC Machining Process, using the method constant zero of external boss Part, boss are fixed by screw, if fastening or Joint failure, boss are subjected to displacement, will directly be weighed wounded and are even scratched part.To increase The reliability fastened by force, in engineering there are two types of common methods: one is being positioned using increasing pin mode, but such method It needs additionally to increase process and cost, another is by increasing lock washer, and the mode of increasing friction force, such method can It reduces part to a certain extent to be subjected to displacement, but not in place when installing, when nut center and excessive bolt-center deviation can still lead Cause pressing force insufficient, unpredictable variation will occur for part status.
Summary of the invention
To solve in the prior art using the part of screw in compression fixing since housing screw loosens, stability subtracts It is weak, so cause part status occur unpredictable variation the problem of, the utility model proposes a kind of connection fasteners.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of connection fastener, it is characterised in that: including bolt, nut, detection ring with a scale and disk spring washer, The nut is socketed on bolt, there is detection ring with a scale on the nut, is disk spring washer below the nut.
The detection ring with a scale includes washer, and the first graduated scale for protruding from washer upper side is provided on the washer With the second graduated scale, the inner surface of first graduated scale and the second graduated scale is provided with graduation mark.
The diameter of the disk spring washer is not more than the circumscribed circle diameter of nut.
First graduated scale and the second graduated scale uses transparent material, and graduation mark is uniformly distributed, and at least three, phase Scale value section between adjacent graduation mark is [h-2p, h+d], and wherein h is nut height, and p is the thread segment screw pitch of bolt, and d is The thickness of disk spring washer.
The washer outer diameter is 1.3-2 times of nut circumscribed circle diameter.
The washer inner ring is regular hexagon or circle, and inner ring profile is greater than nut largest contours, and gasket width is at least 3-5mm。
The working principle of the application are as follows:
The application is suitable for being suitble to any occasion of connection and fastening using screw;When in use, according to connecting component The characteristics of, the screw of suitable size is selected, connecting hole is produced in connecting component, then bolt is put into connecting hole, is put into Butterfly disk spring washer to link position upper surface, tightening nuts are put into detection ring with a scale, and whether detection nut is tightened. In connection and fastening, can be used whether detection ring compresses detecting screw, the reach that engages is met the requirements, work as bolt When tightening, detection ring is concordant with bolt.
The advantages of the application, is:
1, pressing force can be increased by part process boss being fixed using disk spring washer, help to reduce boss The displacement occurred when excision and rotation amount prevent boss from squeezing wound or scratch part.
2, screw, nut are all made of standard component, easy for installation without increasing additional processing cost, may be implemented and existing The linking of row compressing method.
3, use detection ring with a scale can scale convenience of calculation can on the basis of bolt and nut standard component Production becomes standard component, realizes the use under many condition, complex conditions.
4, the present apparatus is attached by the way of bonding with corresponding washer using graduated scale, is installed and easy to make, And transparent material is used, it is easy to use that nut is corresponding tightens position with observation when installation.
5, the detection ring used, in-profile are greater than the largest contours of nut, and detection ring is easy to use, reusable, And it can be used as independent component, be used alone.
Detailed description of the invention
Fig. 1 is connection fastener structural schematic diagram.
Fig. 2 is detection ring structure with a scale intention.
Fig. 3 is connection fastener scheme of installation.
It include: bolt 1, nut 2, detection ring 3 with a scale, disk spring washer 4, washer 5, the first graduated scale 6, the second quarter Spend ruler 7, graduation mark 8, upper connector 9, top bar hole 10, lower connector 11, hole 12 of getting out of a predicament or an embarrassing situation.
Specific embodiment
Embodiment 1
