Description
Technical field
The utility model relates to the locking thread technical field, particularly a kind of screw thread positioning and locking device.
Background technique
At present, the structural type of the locking device that is used to be threaded is a lot, has frictionally locking; Like spring washer, double nut etc.; Also have by machinery type lockingly, like cotter pin, retaining pad or the like, its purpose all is in order to prevent relatively rotating of nut and bolt.Fact proved not quite and do not have under the situation of specific (special) requirements in static load and temperature variation, the effect of above-mentioned several kinds of self-lockings and locking stopping all is effective.But impact shock is being arranged and needing frequent adjustment nut to also have under the situation of alternate load, for example simultaneously: the leading screw of depressing of rolling mill is adjusted nut, according to the demand of steel rolling, needs the tight power of adjustment nut change spring, and requires its self-locking stopping.Above-mentioned for this reason several kinds of locking devices all can not satisfy usage requirement, and exist operation dumb, the problem that anti-loosing effect is not good.
Summary of the invention
The purpose of the utility model provides a kind of screw thread positioning and locking device simple in structure, flexible to operation.
The purpose of the utility model realizes through following technical proposals:
The screw thread positioning and locking device of the utility model; Comprise being provided with externally threaded bolt and the nut that is complementary of bolt therewith, it is characterized in that axially evenly being provided with locating slot, be provided with positioning through hole in the outer surface radial symmetric of said nut at the outer surface of said bolt; This positioning through hole is provided with internal thread; In described positioning through hole, be provided with locking gear, this locking gear is by being provided with the adjusting pin that an outside thread and an end are provided with the adjustment groove, therewith the other end of the adjusting pin spring that fixes and connect; The place kick that is connected of spring is formed therewith, and the outside thread of said adjusting pin and the internal thread of said positioning through hole are complementary.
The quantity of said locating slot is 2-6.
The quantity of said positioning through hole is 1-6.
Said adjustment groove be shaped as in-line or cross.
The characteristics of the screw thread positioning and locking device of the utility model are:
The mode that adopts locating slot to combine with locking gear reaches the purpose of locking thread.When axially tight power reaches usage requirement, through screw-driver precession adjusting pin,, place kick is pushed up in the locating slot to increase the top power of spring to place kick, realize locking stopping.The utility model wide application, except that be applicable to various rotary machines depress or tensioning means, also can play the link effect with fixed equipment, also applicable to the equipment two ends or evenly the five equilibrium occasion time adjustment loosen operation simultaneously.Because every rotation 1/6 circle just gets into a locating slot.Can realize axial micro-scale adjustment, flexibly, accurately.
The utility model is simple in structure, flexible and convenient operation, and fixed effect is solid and reliable, in adjustment range, realizes stepless adjustment, wide application, both convenient production simplified maintenance operation again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
Like Fig. 1, shown in Figure 2; The screw thread positioning and locking device of the utility model; Comprise being provided with externally threaded bolt 1 and the nut 3 that is complementary of bolt 1 therewith that it is characterized in that axially evenly being provided with locating slot 2 at the outer surface of said bolt 1, the quantity of said locating slot 2 is 2-6.Outer surface radial symmetric at said nut 3 is provided with positioning through hole 4, and the quantity of said positioning through hole 4 is 1-6.This positioning through hole 4 is provided with internal thread; In described positioning through hole 4, be provided with locking gear; This locking gear is by being provided with the adjusting pin 6 that an outside thread and an end are provided with adjustment groove 5; The other end of adjusting pin 6 spring 7 that fixes and connect therewith, 8 compositions of place kick of being connected of spring 7 therewith, said adjustment groove 5 be shaped as in-line or cross.The internal thread of the outside thread of said adjusting pin 6 and said positioning through hole 4 is complementary.
The mode that the utility model adopts locating slot 2 to combine with locking gear reaches the purpose of locking thread.When axially tight power reaches usage requirement, through screw-driver precession adjusting pin 6,, place kick 8 is pushed up in the locating slot 2 to increase the top power of 7 pairs of place kick 8 of spring, realize locking stopping.In order to strengthen the locking stopping effect of screw thread, being applicable to powerful device, can three locking gears that symmetrically arranged two locking gears change trisection into be locked, effect is more reliable.
The utility model wide application, except that be applicable to various rotary machines depress or tensioning means, also can play the link effect with fixed equipment, also applicable to the equipment two ends or evenly the five equilibrium occasion time adjustment loosen operation simultaneously.Because every rotation 1/6 circle just gets into a locating slot.Can realize axial micro-scale adjustment, flexibly, accurately.
