Abstract
The invention discloses a bolt puller and an application method thereof. The bolt puller is composed of a body, a sliding block and a bolt adaptor. A fixing check block is arranged at the upper middle portion of the body, a handle is arranged at the upper side of the check block, and a smooth guide rod is arranged at the lower side of the check block. An axial inner threaded hole is formed in the end of the guide rod, and the sliding block is connected to the guide rod in a sleeving mode and can slide. The bolt adaptor is an adaptor with the two sides provided with external threaded connectors, the inner connector is matched with the inner threaded hole of the end of the guide rod on the body, the outer connector is matched with an inner threaded hole in the end of a bolt to be pulled out, and the bolt is pulled out through the impact force of the sliding block to the check block along the guide rod.
Description
Technical field
The application belongs to machine tool class, is not particularly a kind ofly opening wide under environment for the specific purpose tool of belt removal pump nozzle bolt and using method thereof.
Background technology
The spaces such as aircraft do not open wide parts when safeguarding; usually need to dismantle some connecting bolts; and these bolts due to Long-Time Service or be difficult to because of interference engagement decompose; particularly at the connecting bolt dismantling not wide open space position; usually can damage other structures around bolt; this kind of bolt at its center, end, has axial threaded hole usually, and screwed hole is a pump nozzle.
Summary of the invention
The application provides a kind of bolt extracting tool and using method thereof, and this extractor can not only not open wide position quick-detachment bolt, and by changing bolt adapter, can dismantle the bolt of different-diameter easily.
For achieving the above object, the technical scheme of the application is: a kind of bolt extracting tool, by body, slide block, bolt adapter forms, it is characterized in that described body is the rod-like structure of a rigidity, the middle and upper part of body is provided with fixed stop, the upside of block is handle, the downside of block is smooth guide rod, the termination of guide rod is provided with axial internal thread hole, described slide block is the hollow cylinder of a rigidity, can be socketed on guide rod and slide, described bolt adapter is the adapter that there is male connection at two ends, its inner contact is mated with the internal thread hole of body guide rod termination, its lateral joint mates with the internal thread hole of bolt end to be extracted.
During use, first the nut of bolt to be torn open is unclamped, pump nozzle on bolt to be removed is decomposed, expose the internal thread hole of termination, lateral joint on extractor bolt adapter is screwed onto in the internal thread hole of bolt to be removed by the form of being spirally connected, inner contact on bolt adapter is connected in sliding guide internal thread hole, carries out the effect of transmitting force when bolt adapter plays the effect and demounting bolt that connect bolt to be removed and sliding guide; Operator one only holds the handle of extractor body, another holds slide block, by handling the block of slide block reciprocating percussion extractor body on sliding guide, it is made to produce outside impulsive force, drive bolt to be removed to move along nail extractor handle orientations gradually, thus bolt to be removed is dismantled from original bolt hole.
The advantage of the application is, simple and reasonable, slide block is utilized to move on sliding guide the operation principle of the reaction force clashing into block on extractor body, in narrow space, can dismantle fast, easily and connect fastening large-sized bolt, be the specific purpose tool of the large-scale apparatus maintenance and repairs such as aircraft.
Below in conjunction with drawings and Examples, the application is described in further detail:
Accompanying drawing illustrates:
Fig. 1 is the structure principle chart of bolt extracting tool.
Fig. 2 is the rigid body signal of bolt extracting tool.
Fig. 3 is the bolt adapter signal of bolt extracting tool.
Number description: 1 slide block, 2 bodies, 3 bolt adapters, 4 guide rods, 5 blocks, 6 handles, 7 bolts
Detailed description of the invention
See accompanying drawing, as shown in the figure, bolt extracting tool is by body 2, slide block 1, bolt adapter 3 forms, body 2 is rod-like structure of a rigidity, the middle and upper part of body is provided with fixed stop 5, the upside of block 5 is handles 6, the downside of block is smooth guide rod 4, the termination of guide rod 4 is provided with axial internal thread hole, described slide block 1 is the hollow cylinder of a rigidity, can be socketed on guide rod 4 and slide, described bolt adapter 3 is adapters that there is male connection at two ends, its inner contact is mated with the internal thread hole of body guide rod termination, its lateral joint mates with the internal thread hole of bolt 7 termination to be extracted.
Use step is as follows:
First, unclamp the nut of bolt 7 to be torn open, the bolt of the pump nozzle on bolt 7 to be removed is dismantled, expose the internal thread hole of bolt 7 termination to be torn open;
Again the internal diameter of slide block 1 is inserted on the external diameter of guide rod 4; Choose and the bolt adapter 3 wanting the internal thread hole of demounting bolt 7 termination to mate, be threaded by the internal thread hole of the lateral joint of bolt adapter 3 with bolt 7 termination to be removed, bolt adapter 3 inner contact is connected with the internal thread hole of guide rod 4 termination; Operating personnel one hold handle 6, and another holds slide block 1; Finally by slide block 1 commute motion in guide rod 4, repeatedly clash into the block 5 on extractor body with slide block 1, make it produce impulsive force, drive bolt 7 to be torn open to move along extractor handle orientations gradually, thus bolt 7 to be torn open is dismantled from original bolt hole.
Claims (2)
1. a bolt extracting tool, there is axial internal thread hole at the center, termination of this bolt, described bolt extracting tool is by body, slide block, bolt adapter forms, it is characterized in that described body is the rod-like structure of a rigidity, the middle and upper part of body is provided with fixed stop, the upside of block is handle, the downside of block is smooth guide rod, the termination of guide rod is provided with axial internal thread hole, described slide block is the hollow cylinder of a rigidity, can be socketed on guide rod and slide, described bolt adapter is the adapter that there is male connection both sides, its inner contact is mated with the internal thread hole of body guide rod termination, its lateral joint mates with the internal thread hole of bolt end to be extracted.
