Please refer to Fig. 1-5, a kind of angle location locking mechanism, including cabinet 20, rotating shaft 10, locating part 30, lock shaft 40。
Cabinet 20 is equipped with a groove, and rotating shaft 10 is rotatablely installed in groove, and specifically, angle location locking mechanism is also Including bearing 50, top board 51, lower platen 52, rotating shaft 10 is rotatably installed on cabinet 20 by bearing 50, top board 51, under Pressing plate 52 is located above and below bearing 50, plays fixing bearing 50.
Rotating shaft 10 is equipped with a positioning block 11, it is preferable that locating piece 11 and rotating shaft 10 are integrally formed, by under rotating shaft 10 The locating piece 11 being downwardly protrude to form is held, locating piece 11 is located in groove.In addition, locating piece 11 can also be fixedly mounted on rotating shaft 10 lower end.Preferably, locating piece 11 is arc block structure.The top of rotating shaft 10 is plane, and placement needs angle to position Product or part.Rotating shaft 10 rotates in the drive mode, drive mode can using it is pneumatic, surge, be electronic or manual Mode.
The lower section of rotating shaft 10 is equipped with locking hole 12, locking hole 12 towards groove, the rotating shaft 10 during rotation, Locating piece 11 is rotated with rotating shaft 10, and locating piece 11 can contradict the locating part 30 during rotation, when locating piece 11 supports After contacting the locating part 30, lock shaft 40 is inserted into locking hole 12, locks rotating shaft 10, realizes that the angle of rotating shaft 10 is fixed Position, to realize the angle positioning of the product or part that are placed on rotating shaft 10, the rotational angle of certain rotating shaft 10 is regarded and is needed Depending on wanting.
Locating part 30 is Limit screw 31, and angle location locking mechanism further includes stop nut 32, and cabinet 20 is equipped with spiral shell Pit, Limit screw 31 pass through threaded hole, and fixed by stop nut 32, and one end of Limit screw 31 reaches in groove, institute State rotating shaft 10 during rotation, locating piece 11 is rotated with rotating shaft 10, and locating piece 11 can contradict limit during rotation Position screw rod 31.Preferably, there are two Limit screws 31, locating piece 11 rotates in the region between two Limit screws 31.Limit Position screw rod 31 is equipped with screw thread, can be by rotating accurate adjustment front-rear position, and the end of Limit screw 31 is locating piece 11 Position is contradicted, therefore can realize the subtle adjustment of the rotational angle of rotating shaft 10 by the rotation of Limit screw 31, limits spiral shell After the subtle adjustment good position of bar 31, the loosening for preventing Limit screw 31 is tightened by stop nut 32.
Lock shaft 40 can be manual, pneumatic, electronic etc. modes be inserted into locking hole 12, it is preferable that lock shaft 40 includes pin shaft And piston, pin shaft are fixedly mounted on the upper end of piston, piston is connected to external gas circuit, and piston upper end is equipped with the first air inlet 41, living It fills in lower end and is equipped with the second air inlet 42, lock shaft 40 is mounted on the inside of cabinet 20, it is preferable that cabinet 20 is equipped with mounting hole, The lock shaft 40 is mounted in mounting hole, and the lower end of piston is fixedly installed with sealing cover 43, is realized and is sealed by sealing cover 43, The periphery of sealing cover 43 is fixedly installed with circlip 44.With reference to Fig. 2, after the first 41 air inlet of air inlet, lock shaft 40 moves down, Pin shaft leaves the constraint of locking hole 12, and rotating shaft 10 can be rotated;After the second 42 air inlet of air inlet, pin shaft is moved upwards, pin shaft It is inserted into locking hole 12, under the constraint effect of locking hole 12, rotating shaft 10 realizes angle positioning.
In the first embodiment, locking hole 12 is two, and locking hole 12 is towards groove.Rotating shaft 10 turns an angle, Until locating piece 11 and Limit screw 31 contradict, later, 42 air inlet of the second air inlet on corresponding lock shaft 40, pin shaft is upward Movement is inserted a locking hole 12, locks rotating shaft 10, and such rotating shaft 10 completes the angle positioning and locking of a station; When handoff angle, 41 air inlet of the first air inlet on corresponding lock shaft 40, pin shaft moves downward the locking for being detached from locking hole 12, Rotating shaft 10 is rotated toward opposite direction, until the locating piece 11 on rotating shaft 10 touches another Limit screw 31 and stops, later 42 air inlet of the second air inlet on corresponding lock shaft 40, pin shaft move upwards another locking hole 12 of insertion, lock rotating shaft 10, such rotating shaft 10 completes the angle positioning and locking of another station, so recycles the position and lock for realizing two angles Function.
In the first embodiment, the position and lock function an of angle can also be realized.Rotating shaft 10 turns an angle, directly It is contradicted to locating piece 11 and Limit screw 31, later, 42 air inlet of the second air inlet on corresponding lock shaft 40, pin shaft is transported upwards It is dynamic to be inserted a locking hole 12, rotating shaft 10 is locked, such rotating shaft 10 completes the angle positioning and locking of a station, separately One locking hole 12 does not work.
In a second embodiment, locking hole 12 is one, and locking hole 12 is towards groove.Rotating shaft 10 turns an angle, Until locating piece 11 and Limit screw 31 contradict, later, 42 air inlet of the second air inlet on corresponding lock shaft 40, pin shaft is upward Movement is inserted a locking hole 12, locks rotating shaft 10, and such rotating shaft 10 completes the angle positioning and locking of a station, Working principle is identical as second of operating mode in first embodiment, only one locking hole 12 in second embodiment, therefore It can only realize the positioning and locking of an angle.
Preferably, locking hole 12 is truncated cone-shaped, and the cone angle of rotary table is 30 °, and through test of many times, the rotary table that 30 ° of cone angle makes Used time is proper.Preferably, the angle between two locking holes 12 is slightly larger than the angle that rotating shaft 10 positions, above-mentioned first In embodiment, the orientation angle of rotating shaft 10 is set as 90 degree, if the angle between two locking holes 12 is 90 degree, through trying The conical surface for testing lock shaft 40 and locking hole 12 does not have fully mated, and limit effect is bad;If the angle between two locking holes 12 It spends greatly, causes lock shaft 40 and the contact surface of locking hole 12 too small, even without in insertion locking hole 12.Therefore it is counted through realizing The angle for obtaining two locking holes 12 is calculated in 92.34 to 101.06 ranges, may be implemented to lock.And when two locking holes 12 it Between angle when being 94 degree, a cone match of lock shaft 40 and locking hole 12 realizes and locks that and locking effect is best.
Angle location locking mechanism provided by the invention is simple and compact for structure, and when rotating shaft 10 rotates, locating piece 11 is contradicted After locating part 30, the locking of lock shaft 40 and locking hole 12 realizes that angle positioning and locking, locating part 30 can when being Limit screw 31 Precise fine-adjustment is realized to adjust the position of Limit screw 31, and then realizes high-precision angle positioning;And mechanism can be realized The positioning and locking of two angles can also realize the positioning and locking of an angle.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto, The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention Claimed range.
