This vehicle brake drum dismounting device, including pneumatic pick and anchor clamps, anchor clamps comprise support, connecting rod, clamping jaw, and the support is annular steel sheet, and it has center screw hole to open, and both ends are for connecting the pinhole, the double -layered tooth of clamping jaw one end for incurving, other end both ends are for connecting the pinhole, the connecting rod is installed between support and clamping jaw through the round pin axle, the base of pneumatic pick is opened has the draw -in groove, and fastening screw is installed to the draw -in groove both sides, and pneumatic pick front end pick rod passes through the screw thread to be installed on the center screw hole of support, fixed by the nut. The utility model discloses beneficial effect is that the impact drive clamping jaw that utilizes the pneumatic pick during operation constantly to produce draws and shakes what the brake drum went on lasting, and the pulling brake drum produces the displacement to reach the purpose of dismantling the brake drum, reduced repair man's intensity of labour, improved work efficiency, and can not harm brake drum and other spare parts.
Description
Technical field
The utility model is related to a kind of automobile brake drum provision for disengagement, belongs to oil field heavy type special car repairing specific tool skill
Art field.
Background technology
Oil drilling, underground work, heavy special purpose vehicle very huge using the quantity of heavy special vehicle in equipment conveying
Brake drum is to be fitted close with the contact site of tire screw and spindle nose, due to load-carrying big and also often in sewage, greasy filth etc.
Run under poor working environment, brake drum is easy to rust extremely, when maintaining operation, dismounting brake drum is very difficult.Dismantle at present
The conventional gas welding of warp is baked, the method such as sledge hammer strikes, screw top, there is potential safety hazard, inefficiency, repairman's work in construction
Intensity is big, also easy damaged brake drum, causes larger economic loss.
CN201320633240 discloses a kind of automobile brake drum chest expander, by bolt holder, drum axle, bracer, piston, liquid
Cylinder pressure, hydraulic press etc. form, and inject highly pressurised liquid by starting hydraulic press, so that the piston in hydraulic cylinder is outwards produced into hydraulic cylinder
Raw thrust, reaction force after drum axle for this thrust is the pulling force pulling automobile brake drum, by automobile brake drum from drum axle
Drawing is got off.It is static force due to acting on the pulling force on brake drum, poor for the serious brake drum effect of some corrosions, and
Hydraulic system is fragile；Additionally due to vehicle is different, on brake drum, the position of top wire hole is also different, the brake drum of some vehicles
Chest expander cannot be fixed, applicable surface is narrower.
Utility model content
The purpose of this utility model is for dismounting brake drum difficulty of the prior art, easily causes damaged the lacking of brake drum
Fall into, the automobile brake drum provision for disengagement that a kind of structure is simple, applied widely is provided.
Automobile brake drum provision for disengagement of the present utility model, including pneumatic pick and fixture, fixture is by support, connecting rod, set of jaws
Become, support is doughnut-shaped steel plate, has center screw, two ends are connecting pin bores；Jaw one end is aduncate clip tooth, the other end
Two ends are connecting pin bores；Connecting rod is arranged between support and jaw by bearing pin；The base of pneumatic pick has draw-in groove, and draw-in groove both sides are pacified
Equipped with fastening screw, pneumatic pick front end pick rod, by being threadably mounted on the center screw of support, is fixed by nut A, nut B.
It is provided with supporting positive cover, supporting positive cover two ends are hanger, middle is adjusting nut between described jaw and tire screw bar,
The hanger at two ends is respectively fitted on jaw and tire screw bar.
The impact that the beneficial effects of the utility model are constantly be generated when being and being worked using pneumatic pick drives jaw to braking
Drum carries out lasting traction and vibrations, pulling brake drum to produce displacement, thus reaching the purpose of dismounting brake drum, reducing repairing
The labour intensity of personnel, improves operating efficiency, and will not damage brake drum and other parts.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, automobile brake drum provision for disengagement of the present utility model, including pneumatic pick 4 and fixture, fixture by support 1,
Connecting rod 2, jaw 3 form, and support 1 is doughnut-shaped steel plate, has center screw, and two ends are connecting pin bores；Jaw 3 one end is inwardly curved
Bent clip tooth, other end two ends are connecting pin bores；Connecting rod 2 is arranged between support 1 and jaw 3 by bearing pin；The base of pneumatic pick 4
Have draw-in groove, draw-in groove both sides are provided with fastening screw 6, and pneumatic pick 4 front end pick rod is by being threadably mounted at the center screw of support 1
On, fixed by nut A7, nut B8.
It is provided with supporting positive cover 5, supporting positive cover 5 two ends are hanger, middle is adjustment between described jaw 3 and tire screw bar 9
Nut, the hanger at two ends is respectively fitted on jaw 3 and tire screw bar 9.
During brake drum dismounting operation, pneumatic pick 4 is fixed on spindle nose by fastening screw 6, big according to brake drum 10 diameter
Little and spindle nose length, selects the pin-and-hole of correct position on jaw 3, regulates the aperture of jaw 3 it is ensured that jaw 3 and brake drum 10
Keeping parallelism, adjusts the length between two hangers it is ensured that jaw 3 is fitted in brake drum 10 by the adjusting nut of supporting positive cover 5
On surface, the adjustment nut A7 then screwing on pneumatic pick 4 pick rod is displaced outwardly support 1, so that the boss of jaw 3 hooks tight brake drum
10 outer, tightens lock nut B8 and support 1 is fastened on pick rod.Start pneumatic pick 4, compressed air promotes within pneumatic pick 4
Piston does and moves back and forth at a high speed, drives pick rod to be constantly be generated outside impact, this impact passes through support 1, connecting rod 2 drives
The boss of jaw 3 constantly produces pulling force and vibrations to brake drum 10 outer, and brake drum is easily dismantled, easy to operate fast
Victory, improves operating efficiency, and will not damage other parts.
