Description
Technical field
The utility model is related to a kind of automotive service set, especially a kind of automobile hind axle brake drum Quick-disassembling tool.
Background technology
At this stage, low-speed electronic garage industry, existing vehicle are more common using rear-guard form.Rear-guard vehicle using rear axle into
The transmission of action edge, and the brake above rear axle mostly uses drum brake.Rear drum brake mainly by brake drum, rub
Pad and brake cylinder composition.
The installation and use of drum brake are more convenient, but problem once occurs for current stage brake, brake drum
Dismounting becomes the problem of puzzlement auto repair people.Due to the Long Term Contact of friction plate and brake drum, in addition brake drum is passed in rear axle
The coupling torque of moving axis is larger, keeps the dismounting of brake drum extremely difficult.
Current stage mainly carries out rough formula dismounting by tools such as flat mouth screwdriver, crowbar, hammers, because not special
Tool makes dismounting brake drum become a time-consuming, effort, and is easily destroyed the work of other parts.
Invention content
In order to overcome the above-mentioned deficiency of the prior art, the utility model to provide a kind of fast quick-detach work of automobile hind axle brake drum
Tool, the extracting tool can improve the removal efficiency and dismounting quality of brake drum.
The utility model solve its technical problem the technical solution adopted is that：Including rocking arm handle, mandril, precession nut,
Reinforcing rib and workpiece connecting plate, precession nut are connected to the top of workpiece connecting plate by reinforcing rib, and the shaft of mandril passes through spiral shell
Line mode passes through precession nut and, workpiece connecting plate on tool there are one with mandril lower end corresponding aperture vertical with workpiece connecting plate
More than the center hole of mandril diameter, the upper end of mandril is connected with rocking arm handle, and connecting hole, connection are equipped on workpiece connecting plate
The quantity and arrangement in hole are corresponding with the quantity of tire mount above brake drum and position consistent.
Compared with prior art, a kind of automobile hind axle brake drum Quick-disassembling tool of the utility model, is mainly used for small-sized
Automobile brake drum utilizes " pulling out son " principle, by the relative motion of precession nut and mandril, to make mandril and workpiece connecting plate
Relative motion is generated, to make the brake drum being connected on workpiece connecting plate generate relative displacement with brake assembly, makes braking
Drum is detached from brake assembly, realizes steady, the efficient dismounting of brake drum.Simultaneously because the utility model has the advantages of simple structure, real
With, successfully solve the problems, such as that brake drum dismounting is difficult during motor vehicle repair, keep the repair of drum brake more convenient and
Efficiently.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model one embodiment.
Fig. 2 is the vertical view of Fig. 1.
In figure, 1, rocking arm handle, 2, mandril, 3, precession nut, 4, reinforcing rib, 5, workpiece connecting plate, 6, connecting hole, 7, in
Heart circular hole.
Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the scope of protection of the utility model.
Figures 1 and 2 show that the structural schematic diagram of one preferred embodiment of the utility model, after a kind of automobile in figure
Axis brake drum Quick-disassembling tool, including rocking arm handle 1, mandril 2, precession nut 3, reinforcing rib 4 and workpiece connecting plate 5, mandril 2
With 3 structure of precession nut, realize that mandril 2 realizes opposite change in displacement with precession nut 3 by rotating, workpiece connecting plate 5 is real
Existing brake drum is connected by tire mount and extracting tool.Precession nut 3 is connected to work by reinforcing rib 4
The shaft of the top of part connecting plate 5, mandril 2 threadedly passes through precession nut 3 and, workpiece vertical with workpiece connecting plate 5
There are one the center holes 7 that aperture corresponding with 2 lower end of mandril is more than mandril diameter for tool on connecting plate 5, and both material-saving, loss of weight, went back
It rotates convenient for mandril 2 and is finally resisted against on brake drum downwards, preferably force makes mandril 2 generate displacement with workpiece connecting plate 5；Top
The upper end of bar 2 is connected with rocking arm handle 1, and specifically, the mandril 2 can be fixed by welding manner and rocking arm handle 1
Connection；Connecting hole 6 is equipped on workpiece connecting plate 5, preferably, the connecting hole 6 is distributed on the surrounding of center hole 7, even
Quantity and the arrangement for connecing hole 6 are corresponding with the quantity of tire mount above brake drum and position consistent.Wherein, the workpiece
Connecting plate 5 is rectangular, can be other arbitrary shapes, is advisable with the shape of rule.Preferably, the precession nut 3 and work
Part connecting plate 5 is parallel and align center.
In the present embodiment, the reinforcing rib 4 is four, and four reinforcing ribs 4 are distributed on 3 surrounding of precession nut, is reinforced
The upper end of muscle 4 is welded on precession nut 3, and lower end is welded on workpiece connecting plate 5.It is without being limited thereto, the specific number of reinforcing rib 4
Amount, arrangement and connection relation can be selected and be set according to actual needs.
Brake unit (brake drum of brake) to be removed is used into spiral shell by tire mount and workpiece connecting plate 5
Mother is attached, and then presses brake drum with hand and gently rotation rocking arm handle 1 makes it produce relative rotation with precession nut 3,
To make mandril 2 and workpiece connecting plate 5 generate relative displacement, when mandril 2 is withstood on brake drum central shaft, it is rotated further rocking arm handle
Hand 1 makes mandril 2 continue to generate displacement with workpiece connecting plate 5, and under force, brake drum is pulled and made by workpiece connecting plate 5
Dynamic device assembly generates relative displacement, to realize the dismounting of brake drum.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
System, it is every according to the technical essence of the utility model, any simple modification and same variation are made to above example, fallen
Enter within the scope of protection of the utility model.
