Description
Technical Field
The utility model relates to a mechanical equipment installs the field, concretely relates to smallclothes maintenance dismantles structure.
Background
In the field of mechanical equipment, compact structures often exist, and once the structures are assembled together, the structures are difficult to remove without damage, and are not beneficial to subsequent maintenance and repair. Such as a planet carrier on a differential. After the planet wheel carrier is installed on the end cover, the planet wheel carrier is difficult to take down due to the fact that no stress point is disassembled on the planet wheel carrier and the close fit of the planet wheel carrier and the end cover is achieved. The forced removal only results in damage to the precision structure.
Therefore, the utility model discloses a structure is dismantled in smallclothes maintenance to solve the inconvenient problem of dismantling of certain machine part now.
Disclosure of Invention
For solving the not enough of prior art existence, the utility model provides a structure is dismantled in smallclothes maintenance.
The technical scheme of the utility model is that:
the utility model provides a structure is dismantled in smallclothes maintenance, include the mounting, by mounting, a plurality of assembly bolt, a plurality of dismantlement bolt, be provided with a plurality of mounting holes on the mounting, the mounting hole bottom be provided with the silk hole that assembly bolt matches, the silk hole with the internal diameter of mounting hole is the same and has the internal thread. The fixed piece is provided with a plurality of screw holes matched with the screw holes, and the diameter of the screw rod of the dismounting bolt is larger than that of the screw rod of the assembling bolt.
Further, the fixing piece is a planet wheel carrier.
Further, the fixed piece is an end cover.
Further, the specification of the assembling bolt is as follows: m16 × 60.
Further, the specification of the dismounting bolt is as follows: m20 × 70.
Further, the diameters of the mounting hole and the screw hole are both: 17.5 mm.
The utility model discloses the beneficial effect who reaches does:
the utility model discloses a silk hole is the same with the size of the required mounting hole of normal planet wheel carrier installation, does not have the influence to the normal installation and the positioning accuracy of planet wheel carrier. When a user wants to detach the planet wheel carrier for maintenance, the stress point can be obtained only by screwing the detaching bolt into the mounting hole. This way. The planet wheel carrier can be detached only by simple operation without causing damage to the planet wheel carrier.
Furthermore, the utility model discloses still have simple structure, advantages such as the processing of being convenient for, facilitate promotion.
Drawings
Fig. 1 is a schematic view of the normal assembly state of the present invention.
Fig. 2 is a schematic view of the disassembly state of the present invention.
In the figure, 1, a planet wheel carrier; 2. an end cap; 3. assembling a bolt; 4. and (5) disassembling the bolt.
Detailed Description
To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1-2, the utility model provides a structure is dismantled in smallclothes maintenance, including the mounting, by mounting, a plurality of assembly bolt 3, a plurality of dismantlement bolt 4, the mounting is planet wheel carrier 1, planet wheel carrier 1 is used for fixing the last planet wheel of differential mechanism, be provided with a plurality of mounting holes on planet wheel carrier 1, the mounting hole inner wall is smooth. The bottom of the mounting hole is provided with a screw hole matched with the assembling bolt 3, and the screw hole has the same inner diameter as the mounting hole and is provided with an internal thread. The fixed part is an end cover 2, the end cover 2 is used for fixing the planet wheel carrier 1, a plurality of screw holes matched with the screw holes are formed in the end cover 2, and the diameter of the screw rod of the dismounting bolt 4 is larger than that of the screw rod of the assembling bolt 3.
Wherein, the specification of the assembling bolt 3 is: m16 × 60, the specification of the dismounting bolt 4 is: m20 × 70. Since the bottom hole required for mounting the M20 bolt is 17.5mm, the diameter of the mounting hole is: 17.5 mm. For the convenience of installation and improvement of tolerance, the diameter of a screw hole required for installing the M16 bolt is more than 16mm, and the extra part is used as a tolerance, so that the diameter of the screw hole is also as follows: 17.5 mm.
Preferably, the number of the mounting holes is three.
Specifically, the utility model discloses divide into two kinds of states, do respectively: normal assembly state, dismantlement state.
And (3) normal assembly state: when the mechanical equipment is normally used, the assembling bolt 3 is inserted into the threaded hole and screwed into the threaded hole of the end cover 2. Under the action of the assembling bolt 3, the planet wheel carrier 1 is tightly attached to the end cover 2.
The disassembly state is as follows: when the mechanical equipment needs to be maintained due to faults, a user unscrews the assembling bolt 3, screws the disassembling bolt 4 into the mounting hole and screws until the bottom of the disassembling bolt 4 reaches the top of the threaded hole. At this time, the three detaching bolts 4 provide a point of effort for the user, who can easily detach the two parts that are precisely fitted.
After the maintenance is finished, the user can screw the assembling bolt 3 into the threaded hole again so that the planet wheel carrier 1 is tightly matched with the end cover 2.
The utility model discloses not only be applicable to planet wheel carrier 1, still be applicable to all mechanical structure that closely cooperate, compact structure that need dismantle.
The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
