Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The embodiment of the invention provides a kind of pin removals, as shown in Figure 1, the pin removal includes guide spiro rod 1,2 and of pedestal
Handwheel 3.
Fig. 2 is the front view of guide spiro rod, and in conjunction with Fig. 2, specifically, guide spiro rod 1 includes installation thread segment 11 and guiding
The outer diameter of thread segment 12, installation thread segment 11 is less than the outer diameter of guide thread section 12, and installs the rotation direction and guiding of thread segment 11
Oppositely oriented, one end periphery wall that is axially disposed within guide spiro rod 1 of the installation thread segment 11 along guide spiro rod 1 of thread segment 12
On, installation thread segment 11 with the screw hole to plug pin for being threadedly engaged, axial direction setting of the guide thread section 12 along guide spiro rod 1
On the other end periphery wall of guide spiro rod 1, guide thread section 12 is axially slidably inserted into pedestal 2, and handwheel 3 is sleeved on
In guide thread section 12, and handwheel 3 is threadedly engaged with guide thread section 12.
In provided pin removal disassembly bolt through the embodiment of the present invention, installation thread segment 11 is inserted to slotting first
In the screw hole of pin, so that guide spiro rod 1 is fixed together with bolt.Then pedestal 2 is sleeved on outside guide spiro rod 1, so that leading
Pedestal 2 is stretched out to thread segment 12.Then 3 sets of handwheel are filled in guide thread section 12, and screw handwheel 3, until handwheel 3 and platform
Seat 2 offsets.It is oppositely oriented due to installation thread segment 11 and guide thread section 12, so guide spiro rod 1 will not rotate.With setting about
The rotation of wheel 3, guide spiro rod 1 will generate the displacement of bolt backwards, to gradually extract bolt.When needing to dismantle other sizes
Bolt when, the guide spiro rod 1 of corresponding specification is only needed to change, without in addition designing a set of dedicated disassembly work
Tool, so pin removal versatility provided by the embodiment of the present invention is stronger.
Optionally, installation thread segment 11 is fine thread, and guide thread section 12 is coarse thread.
In above-mentioned implementation, installation thread segment 11 needs to be threadedly engaged with the screw hole of bolt, so in order to guarantee to pacify
The degree of firmly installing between thread segment 11 and bolt is filled, installation thread segment 11 can be set to fine thread.Guide thread section 12
It needs to be threadedly engaged with handwheel 3, so in order to guarantee that guide thread section 12 can bear the axial force of the application of handwheel 3, it can
To set coarse thread for guide thread section 12.
Fig. 3 is the side view of guide spiro rod, and in conjunction with Fig. 3, in the present embodiment, the cross section of guide thread section 12 is polygon
