The structural characteristics of the tool comprise a top plate, a top rod, a handle, a drawing screw rod, a claw seat and claw hooks, wherein the top plate and the top rod are connected, the handle and the claw seat are connected, the drawing screw rod is respectively matched with the top plate and the claw seat, and the claw hooks and the claw seat are movably connected. The claw hook is provided with a boss and a hook. The tool has reasonable structure design and convenient and reliable use. The tool can convert tension for dismounting the sliding bearing into torsion, can lead three claw hooks to hook the sliding bearing to outward move through screwing nuts until completely dismounting successfully, is practical, saves time and labor, also can guarantee the integrity of parts during the dismounting process, and is an easy tool which has extremely strong practicability and is used to dismount the sliding bearing.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of instrument that is used to dismantle sliding bearing.
Background technology
Mechanical industry is being undertaken to national economy all departments, comprises that industry, agricultural and social life various aspects provide the task of various advanced in performance, cheap, safe and reliable technical equipments, so hold the balance in modernization construction.Make a general survey of the history of machinery development, from several simple tools, to utilizing lever principle, pulley principle, to invention steam engine, motor, the plant equipment that occurs increasing labyrinth finally embodies the development and the progress of science and technology of civilization of human society invariably.
Now, all used this very practical member of bearing in plant equipment greatly, bearing is subjected to vast mechanical colleague's favor deeply with its special role.But be exactly because its effect, when it just can only realize that this has just brought a lot of inconvenience to mounting and dismounting bearing with transition or interference fit during with other parts assembling.Sliding bearing is exactly a kind of form of expression of bearing, and is the same with other bearings, and sliding bearing and bearing block are with transition or interference fit, and for its dismounting, common extracting tool is to be difficult to realize.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned defective in the prior art, and a kind of instrument that is used to dismantle sliding bearing is provided, it can be used for dismantling with transition or interference fit and the sliding bearing that corresponding parts with it are assembled together.
The technical scheme in the invention for solving the above technical problem is: this instrument that is used to dismantle sliding bearing is characterized in that: it comprises that top board, push rod, handle, drawing screw rod, pawl seat and pawl collude; Described top board is connected with push rod, and handle is connected with the pawl seat, and the drawing screw rod cooperates with top board and pawl seat respectively, and pawl colludes with the pawl seat and flexibly connects; Described pawl colludes and is provided with boss and hook.
The utility model also is provided with nut, and this nut is by being threaded in an end of described drawing screw rod.
Top board described in the utility model is threaded with push rod, and handle is threaded with the pawl seat, the drawing screw rod respectively with top board and pawl seat matched in clearance, pawl colludes then and flexibly connects by hinge with the pawl seat.
The utility model is provided with inwardly outstanding boss at the middle part that described pawl colludes, and is provided with outwards outstanding hook at the head that pawl colludes.
The utility model beneficial effect compared with prior art is: reasonable in design, and easy to use and reliable; The utility model can convert the pulling force of dismounting sliding bearing to torsion, can make three pawls collude hook by fastening nut sliding bearing and moves outward, up to dismantling fully successfully, practical not only time saving and energy saving but also can guarantee the integrality of part in the unloading process, be the light instrument that sliding bearing is dismantled in very strong being used to of a kind of practicality.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model embodiment.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, present embodiment mainly colludes 7 by nut 1, top board 2, push rod 3, handle 4, drawing screw rod 5, pawl seat 6 and pawl and forms.Wherein: nut 1 is by being threaded in an end of drawing screw rod 5, top board 2 is threaded with push rod 3, handle 4 is threaded with pawl seat 6, and drawing screw rod 5 is matched in clearance respectively and between top board 2 and the pawl seat 6, and pawl colludes 7 and then flexibly connects by hinge with pawl seat 6.Simultaneously, collude 7 middle part at pawl and be provided with inwardly outstanding boss 71, and collude 7 head at pawl and be provided with outwards outstanding hook 72.
During use, by push rod 3 and top board 2 entire tool is positioned on the bearing block 8 earlier, make pawl collude 7 places by moving its handle 4 again in the face of the end face of accurate sliding bearing 9 in bearing block 8 inside, the handle 4 of back-outing, hook the end face of sliding bearing 9 by spurring the hook 72 that its drawing screw rod 5 colludes on 7 pawl then in bearing block 8 inside, make pawl collude 7 hooks by fastening nut 1 again and sliding bearing 9 and move outward, up to sliding bearing 9 is disassembled.
The utility model will be dismantled the used pulling force of sliding bearing and convert torsion to, save time and laborsaving; Handle 4 is used for locating detent seat 6 and pawl and colludes 7, back-outs after finish the location and unloads; Drawing screw rod 5 is used for clamping and pulling out sliding bearing 9; The boss 71 that pawl colludes on 7 can stretch by the conehead 51 of drawing screw rod 5.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any structure after the simple transformation of the present utility model is all belonged to protection domain of the present utility model.
