The fast changer for an inner sleeve is characterized in that the thread suspender is sheathed with the nut, and the handle; the umbrella-type bearing is arranged below the nut; the thread suspender passes through the support frame, and the bottom end of the thread suspender is clamped in the middle of the flexible outer clip and is articulated by the cross arm; the cushion block is clamped in the middle of the flexible outer clip, and an outer hook at the bottom end of the flexible outer clip clings to the bottom end of the inner sleeve; the handle is rotated so that the thread suspender is driven to rotate and rise, and the inner sleeve is pulled to rise; therefore, the aim of pulling out the inner sleeve is achieved. The fast changer is simple in structure, convenient and practical, and flexible in operation. Work can be done manually without power driving or consumption. Therefore, the fast changer is high in efficiency, and easy and fast in replacement.
Description
Technical field
The utility model belongs to mechanical frock maintenance tool class, interior cover rapid switcher is applicable to changes positioning sleeve, axle sleeve, bearing, built-in ring flange and edge cover etc., all maintaining units or individual are fit to use, and frock, the equipment of cover are more suitable in especially needing often to change.
Background technology
At present, in enterprise produces, cover in the location such as frock, equipment, mould is needed often to change, when overlapping under not having the locus, hammering into shape out, there is some problem: one, will the parts complete removal of frock, equipment, mould interference be changed and use duration, inefficiency, labour intensity is big; Two, directly weld screw and extract, need electric welding machine.But some moulds of industrial equipment equipment can not bear the high temperature of electric welding, and cover in one of every replacing, need scrap a screw, exists efficient low equally, increases maintenance cost.
Summary of the invention
The purpose of this utility model is to provide a kind of and overlaps the replacing difficulty at present, need parts or welding such as dismounting frock, mould, equipment, there are shortcomings such as length consuming time, labour intensity are big, repeatedly sum up, improve invention repeatedly, made interior cover rapid switcher.Be at the interior cover activity wild card of packing into, the screw thread suspension rod is arranged on the wild card, suspension rod is equipped with nut and handgrip, rotates handgrip and can pull out interior cover.Originally cover rapid switcher is fit to the requirement of business unit's cover in frequent needs such as repairing frock, equipment, mould are changed in, has volume interior cover rapid switcher little, in light weight, easy to carry.
Technical solution of the present utility model is: cover rapid switcher in a kind of comprises screw thread suspension rod, nut, handgrip, umbrella shape bearing, bracing frame, cushion block, movable wild card, transverse arm.It is characterized in that screw thread suspension rod top is set with nut, nut sleeve is equipped with handgrip, the umbrella shape bearing is arranged under the nut, umbrella shape bearing and the pressing of bracing frame interface, the bracing frame interstitial hole is passed in screw thread suspension rod below, and its screw thread suspension rod below is clipped between the movable wild card and to have transverse arm to pass hinged, cover interstitial hole in movable wild card passes, evagination hook dogging accompanies cushion block in interior cover outer face between the movable wild card under it.
On the tooling device that overlaps in bracing frame is fixed on.
Screw thread suspension rod below has the pore volume of installation transverse arm to pass with movable wild card top.
The utility model has the advantages that: 1, simple in structure, volume is little, and is in light weight, easy to carry.What 2, adapt to different directions pulls out cover, end face, bottom surface, side, inclined-plane etc.3, multi-purpose type is changed wild card and cushion block, can extract the interior cover of different inner diameters.4, be fit to business unit, individual, often more the positioning sleeve of exchange device, frock, mould, axle sleeve etc.5, extract in one cover usually and only need 2～3 minutes, consuming time few, the efficient height.6, adopt umbrella shape bearing and serrated nut to cooperate rotation, laborsaving.7, cost is low, need not other power, and maintenance cost is low.
Description of drawings
Accompanying drawing 1 is installed assembling for overall structure of the present utility model and is added cutaway view.
In the accompanying drawing, screw thread suspension rod (1), nut (2), handgrip (3), umbrella shape bearing (4), bracing frame (5), cushion block (6), interior cover (7), movable wild card (8), transverse arm (9).
The specific embodiment
Most preferred embodiment of the present utility model is such: with reference to accompanying drawing, comprise screw thread suspension rod, nut, handgrip, umbrella shape bearing, bracing frame, cushion block, movable wild card etc.Movable wild card (8) is close to needing the interior cover of replacing (7), and the protruding hook of utilization activity wild card (8) lower end hooks interior cover (7) edge, and the centre adds cushion block (6), prevents that movable wild card (8) from pushing back toward the centre when stressed.In addition, movable wild card (8) is connected with screw thread suspension rod (1), transverse arm (9), and screw thread suspension rod (1) passes bracing frame (5) interstitial hole, between bracing frame (5) and rotation nut (2), increase umbrella shape bearing (4), its objective is the frictional force that reduces in nut (2) rotary course, adopt nut (2) simultaneously, both combinations, more laborsaving.Handgrip (3) cooperates with nut (2), and for clockwise rotating, screw thread suspension rod (1) will upwards promote, the screw thread suspension rod is drive activity wild card (8) again, cover in the tight hook of movable wild card (8), screw thread suspension rod (1) rises with interior cover (7), can realize extracting fast interior cover (7).Handgrip (3) is sleeved on nut (2), nut (2) is sleeved on screw thread suspension rod (1) top, nut (2) below dress umbrella shape bearing (4), umbrella shape bearing (4) is close to bracing frame (5) end face interstitial hole top, bracing frame (5) interstitial hole is passed in screw thread suspension rod (1) below, and its below has transverse arm (9) to pass hinged in the middle of being clipped in movable wild card (8).Interior cover (7) interstitial hole is passed in movable wild card (8) below, and the evagination hook dogging of its movable wild card (8) below is at the stress point of interior cover (7) bottom face.When fitting operation uses:
1, movable wild card (8) and screw thread suspension rod (1) and transverse arm (9) are packaged; Movable wild card (8) phase double thread suspension rod (1) fixed position can laterally move, and purpose of design is that buckle is partly put into cover (7), and this design can be applicable to cover in the different-diameter.
2, there is movable wild card (8) the hook part branch to put into and needs to change cover (7) lower surface, hole.
3, after movable wild card (8) buckle partly is close to interior cover (7) stress point place, between two movable wild cards (8), places cushion block (6) and prevent that movable wild card (8) from pushing back toward the centre cause movable wild card (8) to break off relations when stressed.
4, put bracing frame (5) in screw thread suspension rod (1) top, on the tooling device that overlaps in bracing frame (5) is fixed on, stressed supporting-point.
5, umbrella shape bearing (4) is placed with screw thread suspension rod (1) joint face in bracing frame (5) top.
6, the nut (2) of screwing in screw thread suspension rod (1) termination.
7, on nut (2), put handgrip (3).
8, rotary handle (3) drives nut (2), screw thread suspension rod (1) is upwards mentioned, pulling activity wild card (8) moves up, because movable wild card (8) buckle portion has been hooked in interior cover (7) below, along with screw thread suspension rod (1) moves up, thereby extract interior cover (7), so just finished a working cycles.
9, after interior cover (7) is extracted from tooling device, bracing frame (5) and movable wild card (8) be not because of there being stressed supporting-point, and interaction force is eliminated, and interior cover (7) takes out, takes out cushion block (6), restores to the original state.
