Description
Technical field
The invention belongs to the mechanical maintenance tool in use field, relate to the extracting tool of bearing and protective metal shell or non metallic sheath, specifically, is to draw device in a kind of impacting type scalable.
Background technology
In the motor vehicles maintenance, the situation that bearing can't be pulled down from the outside often appears, run into such situation; Just must dismantle bearing, complex operation more internally with after the whole wheel hub dismounting; Not only time-consuming, take a lot of work, require great effort, and be inserted tight fit between bearing and the sheath (bearing block), be difficult for setting about; Demolition works is bigger in addition, takes place easily to squeeze hand, bump hand, causes personal injury.
For this reason, the someone has designed the bearing extractor, is to roll over a crotch at an end of crowbar, and crotch is stretched in the bearing inner race hole; Hook the inner ring of bearing from the outside, hold crowbar with two then and pull outward, bearing is transferred to from sheath (bearing block), this allocation mode of stretching the meaning has significant disadvantages; Be exactly the bad grasp of dynamics, strength is little, and bearing is motionless; Strength is big, and usually other strength is because crowbar has only an impetus; Strength is uneven, and strength is too big, damages bearing or sheath easily.Therefore, be badly in need of the handy bearing extractor of a kind of convenience of research and development.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide in a kind of impacting type scalable and draw device, operation is smoothly, and is convenient handy, and dismounting is quick, saves time, saving of labor, laborsaving, applicable to the dismounting of plurality of specifications bearing.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
Draw device in a kind of impacting type scalable, be made up of handlebar, adjusting rod, impact hammer, jaw components, it is characterized in that: handlebar is made up of a hollow circular-tube; The front end of handlebar is welded with bracing frame, and the rear end of handlebar is provided with handle, and the root weld of handle has fixed disk; The remainder of handlebar is a polished rod, and support frame as described above is made up of left and right ear seat, and impact hammer is enclosed within on the polished rod part of handlebar; Jaw components is made up of left and right pulling claw and the tensioning slide block, the extension spring that are arranged between the left and right pulling claw, and left and right pulling claw shape is identical, and each pulling claw is made up of upper arm section, middle arm section, underarm section disjunctor; The upper arm section is outward-dipping, and middle arm section slopes inwardly, and the underarm section is a straight arm section; The top of the upper arm section of Zola's pawl is hinged through the left ear base of bearing pin and bracing frame, and the afterbody of the underarm section of Zola's pawl is provided with left claw hook, and the top of the upper arm section of right pulling claw is hinged through the right ear base of bearing pin and bracing frame; The afterbody of the underarm section of right pulling claw is provided with right claw hook, and extension spring is connected across in Zola's pawl in the arm section and right pulling claw between the arm section, and said tensioning slide block is a rectangle; The both sides of tensioning slide block are respectively arranged with left and right groove, and the upper arm section of Zola's pawl is embedded in the left groove, and the upper arm section of right pulling claw is embedded in the right groove; The inner face of left and right groove all is the inclined-plane, and the gradient of the inner face of left groove is corresponding with the gradient of the upper arm section of Zola's pawl, and the gradient of the inner face of right groove is corresponding with the gradient of the upper arm section of right pulling claw; The middle part of tensioning slide block is provided with screwed hole, and said adjusting rod is made up of an iron rod, and adjusting rod is set in the tube chamber of handlebar; The front end of adjusting rod is provided with thread head; The rear end of adjusting rod is provided with hexagonal (hexagon)nut, and the thread head of adjusting rod front end is screwed onto with the screwed hole at tensioning slide block middle part, and the hexagonal (hexagon)nut of adjusting rod rear end is resisted against on the rear end mouth of pipe of handlebar.
The present invention has following positive beneficial effect:
One, can regulate the folding angle of claw through adjusting rod, applicable to the dismounting of plurality of specifications bearing.
Two, claw is made up of left and right pulling claw, and the afterbody of each pulling claw all is provided with claw hook, and two claw hooks hook bearing inner race jointly, balance in power, and can not damage bearing or sheath.
Three, convenient handy, a people just can operate, and one holds handle during use, another quick-moving speed pulling impact hammer; Let impact hammer clash into fixed disk, just can let bearing loosening, along axis outer moving progressively, if bearing corrosion; Or with sheath (bearing block) between the tension that cooperates, then can strengthen the strength of pulling impact hammer, if bearing does not have corrosion, and keep suitable elasticity between the sheath; Then can reduce the strength of pulling impact hammer, repeatedly several times, just can be with bearing and sheaths separate, this mode of borrowing the strength allocation bearing of impact hammer; Easy to operate, dynamics can progressively strengthen according to the situation that bearing moves outward, and minimizing that also can be progressively is incremental; Temper toughness with gentleness, dynamics is controlled, and is safe and efficient, can other strength; Only need a people just can bearing be pulled down, save time, saving of labor, laborsaving, greatly reduce the danger of dismantling bearing.
