Description
[technical field]
The utility model relates to the technical field of auto parts machinery, particularly a kind of technical field of nut.
[background technique]
Nut a kind ofly very common is fastenedly connected parts, is widely used in various mechanical device and auto parts machinery.But setter is often difficult to determine that whether nut is fastening and puts in place in actual use, be therefore difficult to guarantee when using for a long time, bolt and nut can not loosen automatically.And in some cases, the loosening of nut, coming off to cause serious accident, causes heavy economic losses.Nut coordinates with bolt and screw rod usually, the structure of existing nut comprises nut body, tapped hole is provided with in nut body, threaded ends on tapped hole and bolt or screw rod cooperatively interacts, in use, easily occurs loosening between nut and bolt or screw rod, affect fastening effect.In the occasion run up and vibrate, nut is very easy to produce and loosens and relative sliding, and cause device damage, serious more likely meets accident.Therefore ensure that this type of nut can tell running with machinery, and don't produce loosening, ensureing mechanical normal operation and safety, is the important technological problems that mechanical producer needs careful attention.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of pressure point formula locking nut, and structure is simple, can make nut with axis during Bolt Connection and radial clamping, play locking effect.
For achieving the above object, the utility model proposes a kind of pressure point formula locking nut, comprise nut body and flange gasket, the sectional shape of described nut body is regular hexagon, described nut body is arranged at the axle center place of flange gasket end face, nut body inside offers through hole, through hole runs through whole flange gasket, screw thread has been attacked in described through hole inside, described nut body and flange gasket are formed in one structure, the upper surface of described nut body offers compressing rectangle groove, and described rectangle groove is connected with through hole.The outer rim of described through hole is also provided with chamfering.
As preferably, the quantity of described rectangle groove is 3, and rectangle groove is evenly distributed in through hole place circumferentially.
As preferably, the degree of depth of described rectangle groove is 1.5 millimeters ~ 3 millimeters.
As preferably, the lower surface of described flange gasket is provided with locking groove, and locking groove is arc-shaped structure, and described locking groove circumferentially arranges around through hole.
As preferably, the quantity of described locking groove is 25, and the spacing often between adjacent two locking grooves is equal.
The beneficial effects of the utility model: the utility model to be opened at the opening of nut by punching equipment and special tooling and is provided with 3 rectangle grooves, destroy the screw thread of partial interior, the effective torque part of its internal thread is suitably out of shape, thus increase frictional force prevents nut itself from getting loose, when this shape can cause nut and Bolt Connection, axis and radial clamping, play the anti-loosing effect after installation.By being provided with locking groove at the lower surface of flange gasket, increasing the contact surface area of nut and workpiece, comparing the combination that plain nut adds packing ring, more firmly and pulling force more greatly, further increase anti-loosing effect.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan structure figure of a kind of pressure point formula of the utility model locking nut;
Fig. 2 is the face upwarding assumption diagram of a kind of pressure point formula of the utility model locking nut.
In figure: 1-nut body, 2-flange gasket, 3-through hole, 4-rectangle groove, the locking groove of 21-, 31-chamfering.
[embodiment]
Consult Fig. 1, Fig. 2, a kind of pressure point formula of the utility model locking nut, comprise nut body 1 and flange gasket 2, the sectional shape of described nut body 1 is regular hexagon, described nut body 1 is arranged at the axle center place of flange gasket 2 end face, nut body 1 inside offers through hole 3, through hole 3 runs through whole flange gasket 2, screw thread has been attacked in described through hole 3 inside, described nut body 1 and flange gasket 2 are formed in one structure, the upper surface of described nut body 1 offers compressing rectangle groove 4, and described rectangle groove 4 is connected with through hole 3.The outer rim of described through hole 3 is also provided with chamfering 31, the quantity of described rectangle groove 4 is 3, rectangle groove 4 is evenly distributed in through hole 3 place circumferentially, the degree of depth of described rectangle groove 4 is 1.5 millimeters ~ 3 millimeters, the lower surface of described flange gasket 2 is provided with locking groove 21, and locking groove 21 is arc-shaped structure, and described locking groove 21 circumferentially arranges around through hole 3, the quantity of described locking groove 21 is 25, and the spacing often between adjacent two locking grooves 21 is equal.
Utility model works process:
A kind of pressure point formula of the utility model locking nut in the course of the work, the upper surface of nut body 1 offers compressing rectangle groove 4, rectangle groove 4 adopts punching equipment and special tooling to press 3 points uniformly at the opening of nut, the degree of depth of rectangle groove 4 is 1.5 millimeters ~ 3 millimeters, rectangle groove 4 destroys the screw thread of partial interior, the effective torque part of its internal thread is suitably out of shape, thus increase frictional force prevents nut itself from getting loose, this frictional force is that the shape of nut effective torque part causes, axis and radial clamping when this shape can cause nut and Bolt Connection, play the anti-loosing effect after installation.Further, flange gasket 2 and nut body 1 are integral type structure, the lower surface of flange gasket 2 is provided with locking groove 21, and locking groove 21 is arc-shaped structure, and locking groove 21 circumferentially arranges around through hole 3, the quantity of locking groove 21 is 25, spacing often between adjacent two locking grooves 21 is equal, and locking groove 21 contacts with the face of being touched, and which increases the contact surface area of nut and workpiece, compare the combination that plain nut adds packing ring, more firmly and pulling force larger.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
