Description

A kind of lock-screw and its locking method
Technical field
The present invention relates to a kind of lock-screw and its locking method, belongs to mode connects for screw technical field.
Background technology
At present in the prior art, screw thread connection it is most widely used, but some specific conditions requirement under, it is necessary to There is a kind of screw not only to couple parts, and the screw belt locking function is closely connected with parts again after being accurately positioned It is integrated, but existing screw in the art is not met by this needs used.
The content of the invention
It is an object of the present invention to provide a kind of simple in construction, easy to use and energy reliable location and the locking of locking connection Screw and its locking method, with overcome the deficiencies in the prior art.
The technical proposal of the invention is realized in this way:
A kind of locking method of lock-screw of the present invention is that first when making lock-screw, lock-screw is fabricated into circle The screw of post shapes, and the front end of the lock-screw in the cylindrical shape makes a small column boss, makes the small column boss Outside diameter be less than lock-screw externally threaded thread root diameter;Simultaneously lock-screw rearward end produce it is recessed Groove, the minimum range for making bottom land to the externally threaded thread root of lock-screw of groove is 0.8~1.5 millimeter;Then will lock Tight screw is screwed into the parts of screwed hole connected and with blind hole, puts down the bottom of the small column boss of lock-screw Face is resisted against on the bottom hole face of the screwed hole of parts, so as to be positioned to lock-screw, when lock-screw and parts are connected to Behind position, instrument is risen by groove spreading using punching, the external screw thread of the lock-screw corresponding to the groove after spreading is produced lug boss, The lug boss is imbedded in parts, lock-screw is produced locking function, prevents lock-screw from rotating and being dragged out.
The above-mentioned punching instrument that rises rushes the instrument that rises for straight rod-shaped of the front end with conical surface block, and the conical surface block can be injected in groove, And the maximum gauge on the conical surface of the conical surface block is more than the distance between bottom land of groove;Inserted in the rise conical surface blocks of instrument of Jiang Chong When entering in groove, conical surface block can be made by groove spreading by way of impacting and rushing the instrument tail end that rises.
For a kind of lock-screw of the invention of the above method, include the spiral shell for being shaped as cylindrical shape of the lock-screw Nail, small column boss is provided with the front end of lock-screw, and the outside diameter of small column boss is less than the externally threaded of lock-screw Thread root diameter;Groove is provided with the rearward end of lock-screw, the externally threaded root of the bottom land of groove to lock-screw The minimum range in portion is 0.8~1.5 millimeter.
Above-mentioned groove is in-line groove or is cross groove.
By adopting the above-described technical solution, the present invention has following technology beneficial effect:The present invention is in lock-screw A small column boss is above provided with, the end face of this small column boss has higher flatness, can carry out standard at work It is determined that position, the minimum range control of bottom land to the externally threaded thread root of lock-screw of the groove of its lock-screw rear end exists In the range of 0.8 millimeter~1.5 millimeters, it so can not only effectively enable groove by spreading, and also assures that lock-screw Intensity.So the present invention is compared with prior art, the present invention not only has the advantages of simple in construction, easy to use, but also The advantages of with energy reliable location and effectively locking connects.It is accurate in screw the invention is particularly suited to need when coupling parts It is determined that the occasion for making screw belt locking function behind position and closely being connected as one with parts uses.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is Fig. 1 right view;
Fig. 3 is the lock-screw of the present invention when being connected with parts and by rushing the attachment structure schematic diagram after the instrument spreading that rises.
Mark in accompanying drawing for:1- lock-screws, 2- small column boss, 3- grooves, 4- conical surface blocks, 5- rush the instrument that rises, 6- Parts, 7- lug bosses, the outside diameter of d- small column boss, D- thread root diameters, the bottom land of L- grooves to lock-screw The minimum range of externally threaded thread root, the distance between the maximum gauge, the bottom land of H- grooves on the conical surface of Q- conical surface blocks.
Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and examples:
Embodiments of the invention:
The locking method of a kind of lock-screw of the present invention, as Figure 1-3, first when making lock-screw 1, by locking screw Nail 1 is fabricated to the screw of cylindrical shape, and the front end of the lock-screw 1 in the cylindrical shape makes a small column boss 2, makes The outside diameter d of the small column boss 2 is less than the externally threaded thread root diameter D of lock-screw 1;Simultaneously in lock-screw 1 Rearward end produce groove 3, the minimum range L for making bottom land to the externally threaded thread root of lock-screw 1 of groove 3 is 0.8 millimeter~1.5 millimeters;Then lock-screw 1 is screwed into the parts 6 of screwed hole connected and with blind hole, made The bottom of the small column boss 2 of lock-screw 1 is flatted against on the bottom hole face of the screwed hole of parts 6, so as to lock-screw 1 Positioned, after lock-screw 1 is connected in place with parts 6, instrument 5 is risen by the spreading of groove 3 using punching, makes the groove after spreading The external screw thread of lock-screw 1 corresponding to 3 produces lug boss 7, and the lug boss 7 is imbedded in parts 6, can so make lock-screw 1 produces locking function, prevents lock-screw 1 from rotating and being dragged out.Used punching rises by instrument 5 can be directly using in the prior art Electronic punching rise instrument, more convenient in order to reduce cost and use, instrument 5 that also punching can be risen is made as front end and carries conical surface block 4 straight rod-shaped rushes the instrument that rises(As shown in Figure 3), the conical surface block 4 is injected in groove 3, and make the conical surface of the conical surface block 4 On maximum gauge Q be more than the distance between the bottom land H of groove 3;Jiang Chong rise instrument 5 conical surface block 4 inject groove 3 in when, It can make conical surface block 4 by the spreading of groove 3 by way of impacting and rushing the tail end of instrument 5 that rises.
For a kind of lock-screw of the invention of the above method, as Figure 1-3, include the shape of the lock-screw 1 For the screw of cylindrical shape, a small column boss 2 is produced in the front end of lock-screw 1, makes the cylindrical straight of small column boss 2 Footpath d is less than the externally threaded thread root diameter D of lock-screw 1;A groove 3 is made in the rearward end of lock-screw 1, can be incited somebody to action Groove 3 is fabricated to in-line groove or is cross groove, and making is, by the bottom land of groove 3 to the externally threaded of lock-screw 1 The minimum range L controls of thread root are in 0.8 millimeter~1.5 millimeters of scope.
