Description
Technical field
It the utility model is related to the dismantling device of mechanical field, more particularly to machanical fastener or keeper.
Background technology
In daily machine-building and maintenance process, often need the alignment pin on body or parts or other are spacing
Part, keeper take out, but the accessory is usually to be interference fitted on body or parts, and in general, which takes out mode, following two
Kind, below with alignment pin distance explanation：
The first：The exposed one end of alignment pin is clamped using clamp energetically, then slightly radially shaking makes alignment pin realize rotation
Turn, so that former dowel hole slightly becomes big, final alignment pin eases out dowel hole.It is former after taking out alignment pin using the method
The aperture of positioning hole on body or parts would generally expand more than 0.2mm, and circularity size can also change, corresponding body and
Parts more than 50% can be scrapped, and the product quality after maintenance remanufactures is had a greatly reduced quality, and it is also very high to scrap waste.
Second：Using welding means, welded together with a bar with alignment pin, utilizing the modes such as drawing-die or percussion hammer
Alignment pin is extracted.After the method takes out alignment pin, body and position components pin-and-hole spoilage are relatively low, but welding spark simultaneously
Also body piece surface is caused to damage hidden danger, and welding needs many equipment coordination work such as welding machine, cost is also higher, to work
Make environment and operator requires also higher.
Above distance be related specifically to the products such as engine or gearbox maintenance remanufacture during.
The content of the invention
Technical problem to be solved in the utility model there is provided a kind of extracting tool, and the extracting tool is particularly applicable in
The maintenance of the part such as engine or gearbox is remanufactured in industry, take out fastener or keeper particularly alignment pin when, simply
Quickly, it is low to operator and environmental requirement, equipment cost is low.
Therefore, the utility model uses following technical scheme：
The clamping element of front end and the guide rod being connected with clamping element, the guide rod are provided with collision block in afterbody, and the guide rod exists
The limiting plate of collision block is provided with after collision block.Collision block is the impact block being fixed on guide rod, and active force acts on impact block can band
The force direction motion of dynamic whole dismounting instrument, specifically, the collision block can be circumferentially positioned on guide rod, the fortune of extracting tool
Dynamic direction is the axial direction of guide rod.
Further, the clamping element includes the chuck for being used to step up keeper of front end, and the chuck is equipped with fastening
Handle, the chuck are fixed after keeper and realize fastening by fastening handle.The chuck is to be realized by fastening handle
Step up and unclamp.
Further, the chuck is arranged with fastener hole, and the fastening handle head is to bore dentation, and and fastener hole
Cooperation tightens up chuck with the rotation of fastening handle, and the fastening handle tail end is a through hole, and a length is interspersed with the through hole
Bar, the stock head diameter are more than through-hole diameter.Head is bigger to ensure that the stock one is brought out and one end is entered.
Further, the clamping element and guide rod are soft connection, and the soft connected mode connects for threaded connection or pin
Connect or chain link.
During the maintenance of the product such as engine and gearbox remanufactures, often need the positioning on body and parts
Pin takes out, but alignment pin is usually to be interference fitted with the dowel hole being assemblied on body or parts, and maintenance at present remanufactures
The method often taken in industry mainly has two kinds：
The utility model discloses one kind to be used for extracting tool, and the instrument may be implemented in the manufactures such as engine and gearbox dimension
It is easy to operate to the fast quick-detach of alignment pin during repairing, while parts and parts will not be caused to damage, particularly
Engine, gearbox this body will not cause to damage.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
The utility model is further elaborated below in conjunction with accompanying drawing.
Extracting tool described in the utility model can dismantle one or more fasteners or keeper.Particularly engine, change
The maintenance of fast case and remanufacture the taking-up occurred in industry.
Embodiment one：
As shown in figure 1, keeper 9 is fixed with body 8.
The extracting tool mainly includes two parts, is the clamping element of front end and the guide rod 3 being connected with clamping element.Specifically
, the clamping element includes the chuck 1 for being used to step up keeper of front end, and the chuck 1 is equipped with fastening handle 2, Liang Zhepei
Close and use, the chuck 1 is fixed after keeper and realizes fastening by fastening handle 2.I.e. described chuck 1 is to pass through fastening handle
Step up and unclamp to realize；
The guide rod 3 is provided with collision block in afterbody, and the guide rod is provided with the limiting plate of collision block after collision block.Collision block 4
To be fixed on the impact block on guide rod, active force, which acts on impact block, can drive the force direction of whole dismounting instrument to move,
Specifically, the collision block 4 can be circumferentially positioned on guide rod, the direction of motion of extracting tool is the axial direction of guide rod.
Further, the chuck 1 is arranged with fastener hole, and the head of fastening handle 2 is cone dentation, and with fastening
Hole, which coordinates, tightens up chuck with the rotation of fastening handle, and the fastening handle tail end is a through hole, and one is interspersed with the through hole
Stock, the stock head diameter are more than through-hole diameter.Head is bigger to ensure that the stock one is brought out and one end is entered.The chuck 1
It can be the electric drill chuck that electric drill uses, different specifications, institute can be selected according to the size of alignment pin, keeper or fastener
It can also be electric drill chuck handle to state fastening handle.
In addition, the chuck is provided with 3 claws.
Further, the clamping element and guide rod are soft connection, and the soft connected mode connects for threaded connection or pin
Connect or chain link.
After chuck 1 clamps keeper or fastener, collision block prolongs guide rod 3 and hit, and is acted on by inertia force and active force, fixed
Position part or fastener and instrument move together, realize and extract and dismantle operation.The positioning of what is more important, body and parts
Hole or positioning aperture will not be destroyed, and the repair quality of product obtains effective guarantee.
It is worthy of note that the restriction for the technical characteristic that the utility model is carried out to right is intended merely to describe
Needs, be not intended to limit right.Modification, change or the equivalent substitution carried out on this basis belongs to this
The protection domain of utility model.
