Abstract
The invention relates to an outer sleeve structure for an integrated screw and nut adjusting and locking device. The outer sleeve structure comprises a sleeve body, a first step and a second step, wherein the first step and the second step are arranged in an inner cavity of the sleeve body and located on the inner wall of the sleeve body in sequence. Compared with the prior art, the outer sleeve structure has the advantages of achieving stable adjustment, being capable of locking nuts and disengaging from locked nuts smoothly and rapidly, and the like.
Description
Technical field
The present invention relates to a kind of low pressure disconnect testing equipment, especially relate to a kind of outer sleeve structure for integrated screw-nut regulating locking device.
Background technology
In the process of production low pressure disconnect, need to split the screw on the overload protecting mechanism bimetal leaf of the Central Shanxi Plain, nut regulates.If adjustment task is completed by manipulator or other automation equipments, so, first under the control of automated circuit, manipulator being moved to the position of workpiece, is secondly regulated screw by manipulator, finally by manipulator to nut screwing clamping, locking; After task completes, manipulator etc. return reset again.
At present for while adjustment screw height of nut, and can the mechanism of fastening nut, only has the integrated screw-nut regulating locking device involved by patent of invention " integrated screw-nut regulating locking device " (patent No.: zl200810200020.8), this device comprises outer sleeve, its embedded SMA actuators is fluted, for encasing outside nut, be convenient to fastening nut, as Figure 1-Figure 2.But in use find, because machined grooves adopts Linear cut mode, make groove up and down along quill shaft to through, when nutting, nut is often absorbed in groove completely, although be convenient to abundant fastening nut, but due to the flexible structure of outer sleeve, when nutting sleeve with between nut often axle center do not overlap, at locking nut, mechanism exits in nut process, nut is easily stuck in sleeve, produce so-called sticky puckery phenomenon, make sleeve on nut, produce pulling force when exiting, harmful effect is produced to former adjustment result.
Summary of the invention
Object of the present invention be exactly provide a kind of stable regulation to overcome defect that above-mentioned prior art exists and can locking nut, depart from smoothly fast the outer sleeve structure for integrated screw-nut regulating locking device of locking nut.
Object of the present invention can be achieved through the following technical solutions:
For an outer sleeve structure for integrated screw-nut regulating locking device, comprise sleeve body and be arranged on first step and the second step of sleeve body inner chamber, described first step and second step are located on the inwall of sleeve body successively.
Described first step inner chamber is provided with is twisted the groove of nut for entangling.
The lowest point, the diagonal angle length L > of described groove is twisted the internal diameter D of the outer rib length D1 > second step of nut.
Described first step bottom is equal along the axial length of sleeve body with groove to the height on its top.
Described first step bottom to the height L1 on its top and by the pass of twisting between the thickness h of nut is: h > L1.
Described L1, h and first step bottom to sleeve body top height L2 between pass be h > L2 > L1.
Compared with prior art, the present invention has the following advantages:
1, because groove only processes the inner chamber place at first step, the internal diameter D of the outer rib length D1 > second step of the nut that the lowest point, the diagonal angle length L > of groove twists, and L1 is always less than by the thickness h of the nut of twisting, when adjusting nut height, outer sleeve can entangle nut smoothly, and enough power can be transmitted, due to fastening nut, make sleeve at locking nut.When exiting, sleeve more easily departs from nut, avoids producing sticky puckery phenomenon, outer sleeve and nut is departed from smoothly, improves job stability and the useful life of equipment.
2, due to h > L2 > L1; ensure that sleeve is when locking nut; the basal plane of nut check can not be touched; avoid the wearing and tearing of cutter head to basal plane; decrease the time that locking nut consumes; protect and be conditioned product, also improve the speed of adjustment.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed execution mode and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 3-Figure 5, a kind of outer sleeve structure for integrated screw-nut regulating locking device, comprise sleeve body and be arranged on first step a and the second step b of sleeve body inner chamber, described first step a and second step b is located on the inwall of sleeve body successively.Described first step a inner chamber is provided with is twisted the groove of nut for entangling, and groove is L1 along the axial length of sleeve body, equal to the height on its top with first step bottom.
The lowest point, the diagonal angle length L > of described groove is twisted the internal diameter D of the outer rib length D1 > second step of nut, and the dimension D 1 according to nut determines dimension D, L.
Described first step bottom to its top height L1 and by twist the thickness h of nut, first step bottom to sleeve body top height L2 between pass be h > L2 > L1, according to the thickness h of nut determine height L1, L2.
Claims (6)
