Description

A kind of rotating shaft extracting tool

Technical field

The utility model relates to a kind of instrument, especially a kind of rotating shaft extracting tool.

Background technology

Some heavy trucks have employed the independent suspension of double wish-bone arm type now.Keep in repair time, due to the chassis limited space of vehicle, cause some instruments cannot close to or usage space not enough, thus make the rotating shaft dismounting difficulty on transverse arm position, install and dismounting time very inconvenient, skid when also easily there is user's hand-held simultaneously, cause collide with injured.

Utility model content

For solving the above-mentioned technical problem mentioned, the utility model provides a kind of rotating shaft extracting tool, space when it can shorten operation effectively, reduces the labour intensity of user, increases work efficiency.

Rotating shaft extracting tool described in the utility model, it includes fastener head 1, slide bar 2, sliding hammer 3 and limiting plate 4; Described fastener head 1 outer surface of cupular part is provided with external screw thread, and this external screw thread matches with rotating shaft 6 internal thread; Described slide bar 2 is a long guide rod, and this slide bar 2 one end is fixedly connected with bottom fastener head 1; Described sliding hammer 3 center offers through hole, and sliding hammer 3 is sheathed on outside slide bar 2 by this through hole, and can be free to slide along slide bar 2 axial direction; Described limiting plate 4 is fixedly installed on the other end of slide bar 2 relative to fastener head 1.Operate use time, user by fastener head 1 with rotating shaft 6 by screw threads for fastening, then utilize sliding hammer 3 inertia that slides rotating shaft 6 to be dismantled.The fastening place of this kind of mode stablizes, and the formation of disassembling section is simultaneously limited by guide rod 2, there will not be instrument to rock and causes the situation of damaging to occur.

In the present embodiment, described sliding hammer 3 is a sagittal plane towards the side of limiting plate 4, and limiting plate 4 is towards the Yi Weiyi sagittal plane, side of sliding hammer 3.Sliding hammer 3 passes through planar design with the contact surface of limiting plate 4, so that the contact area between two parts is maximized, and stability when raising limiting plate 4 pairs of sliding hammers 3 are spacing effectively.

In the present embodiment, sliding hammer 3 is provided with two handle 5, two handles 5 and is arranged at sliding hammer respectively relative in the offside outer rim of axis direction.The handle 5 that offside outer rim is arranged respectively can allow user be operated by hand-held handle 5, and simplify the operation difficulty further, increases work efficiency.

In the present embodiment, fastener head 1 and the mode that is fixedly connected with of slide bar 2 are that bolted is connected, and the screw thread between fastener head 1 and slide bar 2 designs for derotation.Utilize dismountable screw threads for fastening connected mode, and fastener head can be changed at any time when the rotating shaft being suitable for different size, improve the scope of application of this extracting tool, derotation simultaneously between fastener head 1 and slide bar 2 designs also can avoid instrument to occur dropout phenomenon in operation, reduces the injured risk of work.

Detailed description of the invention

Below in conjunction with embodiment and respective drawings, the technical solution of the utility model is described in detail, to enable those skilled in the art's understanding clearly scheme of the present utility model, but does not therefore limit protection domain of the present utility model.

The utility model provides a kind of rotating shaft extracting tool, space when it can shorten operation effectively, reduces the labour intensity of user, increases work efficiency.

Specifically, rotating shaft extracting tool described in the utility model, it includes fastener head 1, slide bar 2, sliding hammer 3 and limiting plate 4.Described fastener head 1 outer surface of cupular part is provided with external screw thread, and this external screw thread matches with rotating shaft 6 internal thread.Described slide bar 2 is a long guide rod, and this slide bar 2 one end is fixedly connected with bottom fastener head 1.Described sliding hammer 3 center offers through hole, and sliding hammer 3 is sheathed on outside slide bar 2 by this through hole, and can be free to slide along slide bar 2 axial direction.Described limiting plate 4 is fixedly installed on the other end of slide bar 2 relative to fastener head 1.When operating use, fastener head 1 and rotating shaft 6 are passed through screw threads for fastening by user, and then hand-held sliding hammer 3 applies larger power by fastener head 1 to limiting plate 4 direction.Because sliding hammer 3 can be free to slide along slide bar 2 axial direction, therefore under user's effect more energetically, sliding hammer can move towards limiting plate 4 with higher speed, and final kinetic energy is released on limiting plate 4 completely, and applies one in contrast to the momentum in fastener head 1 direction to limiting plate 4.Be fixedly connected with because limiting plate 4, slide bar 2 and fastener head 1 are, fastener head 1 is fixed by thread fiting mode and rotating shaft 6 again, and the momentum that limiting plate 4 bears is transformed in rotating shaft 6 effectively, and makes it move towards axial outside direction.Utilize aforesaid operations step and principle, user only needs hand-held sliding hammer 3 and constantly force makes sliding hammer 3 clash into limiting plate 4, thus rotating shaft 6 is dismantled the most at last.Rotating shaft extracting tool structure described in the utility model is simple, and the region very limited in operating space has use value too simultaneously, effectively improves operating efficiency.

Below be only that preferred embodiment of the present utility model is described; the technical solution of the utility model is not limited to this; the any known distortion that those skilled in the art do on the basis that major technique of the present utility model is conceived all belongs to the claimed technology category of the utility model, and the concrete protection domain of the utility model is as the criterion with the record of claims.
