Description
Technical field
The present invention relates to the specific purpose tool of dismounting, mounting fastener, particularly a kind of for dismantling and install the installing sleeve of machine filter joint.
Background technology
Machine filter joint is with externally threaded securing member, by loading onto nut in the non-assembling male end at two ends, lock, for fastening machines part etc., after general assembling, also need by two mutually the nuts of locking take off, efficiency of assembling is lower.Some locks machine filter joint by sleeve now, this sleeve is generally combined by internal thread bar and hexagonal swivel nut, being about to the internal thread of sleeve and the non-assembling male end of machine filter joint locks, although this structure operating efficiency is higher, but there is following defect: 1, machine filter joint is being packed into after part completely, need sleeve is separated with the internal thread packing into bar, and when backing out sleeve, machine filter joint is also unscrewed together or backs out, not only make stud disposablely not be seated, also can destroy the threaded engagement of stud and screw; 2, when sleeve is back-outed, need to be with an other spanner or sleeve hexagonal swivel nut, guarantee sleeve machine filter joint when rotating backward can and then not rotate, and affects the fastening effect between part, has complex operation, machine filter joint easily by defects such as band turn; 3,, owing to there is no disconnecting prevention structure between the internal thread screw rod in sleeve and hexagonal swivel nut, when completing hexagonal swivel nut while exiting, sleeve easily departs from internal thread screw rod.
Summary of the invention
The object of the invention is to propose a kind of simple and reasonable for structure, can be easily sleeve reversion be taken out, and the machine filter joint machine filter jiont treatment sleeve that can not turned by band.
Machine filter jiont treatment sleeve of the present invention consists of front sleeve and rear sleeve, and described front sleeve is provided with the internal thread hole axially running through; One end of described rear sleeve is provided with the double-screw bolt that diameter is less than rear sleeve diameter, and described double-screw bolt screws in to the internal thread hole of front sleeve; Described rear sleeve is provided with projection towards the end of front sleeve, and described front sleeve is provided with convex body towards the end of rear sleeve, and described projection and convex body are on same circumference, and the common occupied central angle of projection and convex body is less than 360 degree.
The operation principle of above-mentioned machine filter jiont treatment sleeve is as follows:
The process of installing sleeve: the abutting end of first internal thread hole of front sleeve being aimed to machine filter joint, then sleeve after utilizing torque spanner or pneumatic tool to rotate, in the time of rear sleeve rotating, drive projection and double-screw bolt to rotate, projection has rotated after certain angle, will be blocked by front pullover convex body, now, sleeve passes through projection, convex body drives front sleeve to rotate, so that machine filter joint screws in the internal thread hole of front sleeve, until the end face of machine filter joint and double-screw bolt offsets, because the projection of rear sleeve and the convex body of front sleeve are mutually spacing fixing, the continuation rotation of front sleeve can make machine filter joint and double-screw bolt end face compress, under the effect of this pressure, now sleeve starts to drive machine filter joint synchronous rotary, the other end of machine filter joint is screwed in the screwed hole of part to be connected and screw and be in place.
The process of pulling off sleeves: rotate backward rear sleeve, drive double-screw bolt and projection synchronously to rotate, now, the projection of rear sleeve and the convex body of front sleeve depart from (departing from spacing), and double-screw bolt reverse rotation is gradually away from machine filter joint, machine filter joint is no longer subject to the pressure of double-screw bolt; Rear sleeve continues after reverse rotation certain angle, and the projection of rear sleeve turns to the other end of the convex body of front sleeve, and again by convex body, blocked spacing, at this moment after sleeve by projection, convex body, drive front sleeve synchronous backward to rotate so that sleeve screws out machine filter joint.At sleeve, screw out in the process of machine filter joint, because the thrust between double-screw bolt and machine filter joint has disappeared, therefore, during front sleeve rotation, can not drive mounted machine filter joint to rotate together, thereby guarantee that sleeve reversion does not need auxiliary spanner to take out easily while taking out, and can not destroy the immovable fitting between machine filter joint and part.
Further, the end face of described double-screw bolt is provided with cavity, in described cavity, is movably installed with steel ball, and the part of described steel ball is exposed to the end face of double-screw bolt.Steel ball can offset prior to end face and the machine filter joint of double-screw bolt like this, makes face contact change a contact into, and steel ball can roll, thereby reduces the frictional force to machine filter joint, avoids machine filter joint to cause damage.
Further, spacing for better steel ball being carried out, described cavity is spherical cavity, and the diameter that described spherical cavity is positioned at the opening of connecting axle end face is less than the diameter of steel ball.
Further, described rear sleeve and double-screw bolt are Split type structure, and described rear sleeve is provided with the slotted eye of an end opening, and one end away from front sleeve of described double-screw bolt snaps in to described slotted eye, to realize the synchronous rotary of double-screw bolt and rear sleeve; Described rear sleeve and double-screw bolt are provided with the disconnecting prevention structure that prevents that double-screw bolt from departing from.Rear sleeve and double-screw bolt are designed to Split type structure, can conveniently process.
Further, the cross section of one end away from front sleeve of described slotted eye and double-screw bolt is the regular polygon that shape conforms to, and slotted eye can apply uniform rotatory force to double-screw bolt like this, drives double-screw bolt synchronously to rotate.
Further, the card column snapping in groove that the groove that described disconnecting prevention structure is provided with by double-screw bolt side and rear sleeve are provided with forms, and this card column can adopt the screw through rear sleeve wall, fixing more convenient.
Further, the side of described rear sleeve is provided with cutting face or rear sleeve is provided with hexagonal flange convex body, to facilitate, utilizes sleeve after spanner clamping, thus sleeve after rotating.
Further, the internal thread hole of described front sleeve consists of two sections of different internal thread holes of diameter, after wherein approaching, the diameter of one section of internal thread hole of sleeve is greater than the diameter of another section of internal thread hole, after approaching like this, the screw thread specification of one section of internal thread hole of sleeve just no longer must be consistent with the screw thread specification of machine filter joint, be convenient to processing, and can avoid that to screw in the internal thread hole that deeply caused machine filter joint to screw in front sleeve excessively shallow because of double-screw bolt, affect front sleeve and machine filter joint between lifting surface area too small.
Further, the end of described front sleeve is for being taper, not only attractive in appearance, can also alleviate overall weight.
Further, described double-screw bolt screws in at least 360 degree in the internal thread hole of front sleeve, and under projection, convex body spacing, double-screw bolt can not surpass 360 degree with respect to the rotation of front sleeve, can guarantee that like this, in the process of forward and reversion, double-screw bolt can not screw out the internal thread hole of front sleeve.
Machine filter jiont treatment tube-in-tube structure of the present invention is simple, cost is low, easily realization, machine filter joint can be installed easily, and can after machine filter jiont treatment, at an easy rate sleeve reversion be taken out, and in the process of taking-up sleeve, can not drive the reverse rotation of machine filter joint, thereby guarantee the installation quality of machine filter joint.
