Abstract

The utility model relates to the technical field of manufacture of assembly and disassembly tools, in particular to a jacking puller for assembly and disassembly of bearings, gears and the like. A multifunctional flexible puller is characterized in that a movable screw sleeve is arranged on an inner sleeve wall of an outer shaft sleeve, one of the movable screw sleeve is combined with a screw rod which is arranged inside a bearing positioned at one end inside the outer shaft sleeve, the other end of the screw rod is connected with a steering wheel which is provided with a shaft sleeve handle, and a conical block is welded to the movable screw sleeve which is capable of retracting at an opening of the outer shaft sleeve. A hook claw for holding a chain is arranged on a movable hook placed on a grooved disk which is fixedly welded to the outer shaft sleeve, one end of the chain is connected with a draw hook provided with a through hole, and a rope or a chain is arranged inside the through hole. The height and the depth of the grooved disk can be adjusted by turning the screw rod, and disassembly of different mechanical workpieces such as gears, pulleys, sleeves and bearings can be realized by connecting the draw hook.

Description

A kind of multi-functional sign indicating number that draws flexibly

Technical field

The utility model relates to a kind of handling instrument manufacturing technology field, the thruster of loading and unloading such as particularly a kind of bearing, gear, specifically a kind of multi-functional sign indicating number that draws flexibly.

Background technology

In mechanical industry maintenance, usually run into bearing, the separation dismounting of workpiece such as circular sleeve, general just with two pawls or three-jaw thruster when dismounting, but different because of concrete situation, be difficult to change as the circle pin, inapplicable dismounting does not have the workpiece of central point.Present employed thruster is relatively more fixing and dumb, generally all be applicable to large-scale and mechanical field-strip single variety, be not suitable for maintenance to little workpiece, if and in maintenance process with instruments such as tup to workpiece such as bearing force the dismounting, make damages such as bearing easily, so that in the service life of having reduced machine, in service work, get half the result with twice the effort.

Summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, easy to use, flexibility is strong draws sign indicating number.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of multi-functional sign indicating number that draws flexibly, mainly be built-in with a movable swivel nut by the outer shaft sleeve, movable swivel nut one end combines with screw rod, the screw rod other end is connected with commutation shelves wheel, the outer shaft sleeve also comprises welding one groove disk, the groove disk is additional to be laid two or more and moves hook, it is characterized in that: the inner tube wall of outer shaft sleeve is settled a movable swivel nut, movable swivel nut one end combines with screw rod, screw rod is placed in the bearing that an end is arranged in the outer shaft sleeve, screw rod one end connects place commutation shelves wheel again, commutation shelves wheel design again has the axle sleeve handle, and described movable swivel nut axle sleeve tube port position outside is flexible, and movable swivel nut also welds place awl piece, the also fixing welding groove of described outer shaft sleeve disk, additional the laying of groove disk moved hook, and mobile hook has also designed the hook pawl, and the hook pawl is to place the rope chain, the rope chain other end connects drag hook, and drag hook is furnished with open-work.

Owing to adopted technique scheme, the described multi-functional sign indicating number that draws flexibly, regulate the height and the degree of depth of groove disk by rotating screw bolt, realize dismounting by connecting drag hook to different mechanical workpieces such as gear, belt pulley, sleeve and bearing, prevent that compulsory dismounting from bringing unnecessary harm to these workpiece, and easy to use, whole service work is got twice the result with half the effort.

The utlity model has rational in infrastructurely, safe and convenient to use, be convenient to production and processing, low cost of manufacture, intensity height, sturdy and durable, advantage such as fast flexible, laborsaving is applicable to the dismounting maintenance of large, medium and small bearing or body etc.

Description of drawings

Fig. 1 is this novel a kind of multi-functional yard main body schematic diagram that draws flexibly.

Indicate among the figure: the 1-screw rod, the movable swivel nut of 2-, 3-groove disk, 4-commutation shelves wheel, 5-moves hook, the 6-screw thread, 7-rope chain, the 8-screw handle, 9-axle sleeve handle, the 10-drag hook, the 11-open-work, 12-bores piece, 13-bearing, 14-change-over key, 15-outer shaft sleeve.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

Referring to shown in Figure 1, a kind of multi-functional sign indicating number that draws flexibly, comprise that outer shaft sleeve 15 is built-in with a movable swivel nut 2, movable swivel nut 2 one ends combine with screw rod 1, screw rod 1 other end is connected with commutation shelves wheel 4, outer shaft sleeve 15 also comprises welding one groove disk 3, and groove disk 3 is additional to be laid two or more and move hook 5.

As further improvement, it is characterized in that: the inner tube wall of outer shaft sleeve 15 is settled a movable swivel nut 2, movable swivel nut 2 one ends combine with screw rod 1, screw rod 1 is placed in the bearing 13 that an end is arranged in the outer shaft sleeve 15, screw rod 1 one ends connect place commutation shelves wheel 4 again, and commutation shelves wheel 4 design again has axle sleeve handle 9.

As further improvement, described movable swivel nut 2 shaft sleeve is outside located to stretch for 15 mouthfuls, and movable swivel nut 2 also welds place awl piece 12.

As further improvement, the also fixing welding groove of described outer shaft sleeve 15 disk 3, groove disk 3 additional laying are moved hook 5, mobile hook 5 also design has the hook pawl, the hook pawl is to place rope chain 7, and rope chain 7 other ends connect drag hook 10, and drag hook 10 is furnished with open-work 11, comprise in the described open-work 11 and arrange a rope or chain, purpose is in use workpiece further to be linked closely.

During use, regulate the height and the degree of depth of groove disk 3 by rotating screw bolt 1, by movable swivel nut 2 outside 15 mouthfuls of shaft sleeves outer flexible in, 12 contacts of awl piece are on fixture, rotate commutation shelves wheel 4 and change-over key 14 is set, the telescopic action of movable swivel nut 2 is provided,, connects drag hooks 10 by rope chain 7 again and realize dismounting different mechanical workpieces such as gear, belt pulley, sleeve and bearing etc. again by moving hook 5 flexible Application.

Though this novel embodiment with reference to specific description is described, it is not restricted to this embodiment, and is only limited by dependent claims.Can be contemplated that those skilled in the art can make various modifications and improvement to embodiment under the situation that does not depart from scope of the present invention and essence; all technical schemes that mapping mode obtains that adopts equivalence to replace or be equal to all drop in this novel protection domain.
