Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
The disassembly of existing bearing mostly uses special stripping attachment disassembly bearing, as duplex pull rod stripping attachment and three pull rods are dismantled
Device causes high production cost since structure is complicated for above-mentioned stripping attachment, and pull rod stripping attachment needs the pressure born when bearing removal
Power or pulling force are larger, and the shaft portion of above-mentioned stripping attachment is easy to loosen and even be broken, and cause stripping attachment high failure rate.
Referring to Figure 1, the present embodiment provides a kind of bearing removal structure, which includes that vice 10 and two tear open
Device 20 is unloaded, during bearing removal, two stripping attachments 20 are symmetrically placed in the two sides of the fixing axle of bearing, the clamping part of vice 10
11 pairs of two stripping attachments 20 squeeze.
Fig. 2 is referred to, in order to solve the above-mentioned technical problem, line fulcrum triangular in shape is formed on stripping attachment 20
21, power part 22 and resistance part 23.Pass through between fulcrum 21 and power part 22 and between power part 22 and resistance part 23
Connecting rod connection, since stripping attachment 20 need to complete the disassembly of bearing, fulcrum 21, power part 22, resistance under the extruding of vice 10
Portion 23 and connecting rod can use integrated molding, be cut such as casting and forming, forging molding or using block of metal block by CNC
Molding.
When dismantling to bearing, two stripping attachments 20 are symmetricly set on to the two of the fixing axle 40 of bearing 30 to be removed
Side, the fulcrum 21 of two stripping attachments 20 contact with the fixing axle 40 of bearing 30 to be removed, fixing axle 40 are clamped, and move
Power portion 22 is contacted with the clamping part 11 of vice 10, and resistance part 23 is then contacted with the end face of bearing 30 to be removed.The clamping of vice 10
When portion 11 squeezes power part 22, stripping attachment 20 forms lever, and the fulcrum 21 contacted with fixing axle 40 is fulcrum, fulcrum
The distance between power position in portion 21 and power part 22 forms power arm, and the resistance in fulcrum 21 and resistance part 23 is made
Resistance arm is then formed with the distance between line, when resistance part 23 is moved radially towards bearing 30, in order to ensure the sled of resistance part 23
Dynamic bearing 30, the shape of resistance part 23 are wedge shape, and wedge-shaped resistance part 23 can be towards the diameter of bearing 30 under the action of vice 10
To extruding, bearing 30 then can enable bearing 30 loosen in the axial movement of fixing axle 40, and then achieve the effect that dismantle bearing 30,
Structure is simple, easy to operate, also reduces the failure rate of stripping attachment, reduces the disassembly cost of bearing.
It should be noted that since the connection between bearing 30 and fixing axle 40 is more firm, in disassembly bearing 30
When need to be dismantled using more big dynamics, acting on the dynamics of fulcrum 21, power part 22 and resistance part 23 then can be at
Increase again, in order to avoid the connecting rod cracking between three influences the normal disassembly of bearing 30, fulcrum 21, power part 22, resistance
Power portion 23 and connecting rod then need to be made of matter hard material.
Embodiment 2
Referring to Figure 1-2, the present embodiment provides a kind of bearing removal structure, which includes vice 10 and two
Stripping attachment 20 is likewise formed with line fulcrum 21 triangular in shape, power part 22 and resistance part 23 on stripping attachment 20.Fulcrum
It is connected by connecting rod between portion 21 and power part 22 and between power part 22 and resistance part 23.
Refer to Fig. 2, as the further improvement of technical solution, the present embodiment unlike the first embodiment, in power part
The end face contacted on 22 with the clamping part 11 of vice 10 is in the cambered surface swelled towards clamping part 11.In clamping part 11 to stripping attachment 20
When being squeezed, stripping attachment 20 can generate rotation with clamping part 11, and the fulcrum for generating rotation with clamping part 11 is then located at power
At portion 22, i.e., clamping part 11 can generate friction with power part 22, and above structure enables to the clamping of power part 22 Yu vice 10
Relative motion between portion 11 reaches smooth, and the clamping part 11 of the power part 22 or vice 10 that avoid stripping attachment 20 causes to damage
It is bad.
Embodiment 3
Referring to Figure 1, the present embodiment provides a kind of bearing removal structure, which includes that vice 10 and two tear open
Device 20 is unloaded, line fulcrum 21 triangular in shape, power part 22 and resistance part 23 are likewise formed on stripping attachment 20.Fulcrum
It is connected by connecting rod between 21 and power part 22 and between power part 22 and resistance part 23.
As the further improvement of technical solution, the present embodiment is unlike Examples 1 and 2, fulcrum 21 and resistance
The distance between portion 23 is greater than the thickness of bearing 30 to be removed, which can be placed in bearing 30 during bearing removal
Between fulcrum 21 and resistance part 23, so that bearing 30 is mobile towards fulcrum 21 in disassembly process, reduces bearing 30 and tear open
The difficulty unloaded.
Fig. 2 is referred to, for the above-mentioned detaching structure for enabling bearing 30 mobile towards fulcrum 21, the direction on resistance part 23
The side of fulcrum 21 is arranged in slope surface；Alternatively, being arranged towards the side of fulcrum 21 in cambered surface on resistance part 23.The structure
It further reduced the difficulty of bearing removal
Embodiment 4
Referring to Figure 1, the present embodiment provides a kind of bearing removal structure, which includes that vice 10 and two tear open
Device 20 is unloaded, line fulcrum 21 triangular in shape, power part 22 and resistance part 23 are likewise formed on stripping attachment 20.Fulcrum
It is connected by connecting rod between 21 and power part 22 and between power part 22 and resistance part 23.
Since fulcrum 21 plays the role of the fixing axle 40 in fixing bearing 30, in order to improve the firm of fixing axle 40
Property, refers to Fig. 3, and the present embodiment is unlike the embodiments above, in fulcrum 21 with the fixing axle of bearing 30 to be removed
