Description
Technical field
The utility model belongs to everyday tools technical field, and in particular to a kind of corrosion bolt disassembling tool.
Background technology
It is all very universal using the equipment of bolt fastening, component, pipeline etc. in underground coal mine, but because of underground humidity, bolt
It gets rusty easily, using being all difficult dismounting after spanner or extension bar, is also deposited during using sledgehammer and chip-axe blocks by force
It is generating spark or is taking off the security risk hammered into shape and hurted sb.'s feelings, causing to delay job schedule, increase workload.
Invention content
The utility model provides a kind of corrosion spiral shell for corrosion Bolt dismantling difficulty and the unsafe problem of disassembly process
Bolt extracting tool.
The utility model adopts the following technical solution：
A kind of corrosion bolt disassembling tool, including stock and hollow handle, one end of handle is connected with one end of stock,
The connecting pin of stock and handle is equipped with trepanning, and tapping is equipped with cutter, is equipped with resetting spring in handle and transmits the steel of torque
Ball, the other end of handle be equipped with internal thread and with the matched bolt of internal thread, the cutter head of cutter passes through the trepanning of stock, cuts
The other end of cutter is equipped with lantern ring, and resetting spring is sleeved on lantern ring, and steel ball is between resetting spring and bolt.
The inner cavity of the steel ball and handle is slidably matched.
The diameter of the steel ball is bigger than the diameter of resetting spring.
The stock is round stock.
The beneficial effects of the utility model are as follows：
1. the utility model is easy to operate, removal efficiency is high；
2. the utility model safe operation process；
3. the utility model reduces hand labor intensity.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Wherein：1- stocks；2- handles；3- cutter；4- resetting springs；5- steel balls；6- bolts.
Specific embodiment
With reference to attached drawing, the utility model is described further.
A kind of corrosion bolt disassembling tool, including stock 1 and hollow handle 2, one end of handle 2 and one end of stock 1
The connecting pin of connection, stock 1 and handle 2 is equipped with trepanning, and tapping is equipped with cutter 3, and resetting spring 4 is equipped in handle 2 and is passed
The steel ball 5 of torque is passed, the other end of handle 2 is equipped with internal thread and bolt matched with internal thread 6, and the cutter head of cutter 3 is worn
The trepanning of stock 1 is crossed, the other end of cutter 3 is equipped with lantern ring, and resetting spring 4 is sleeved on lantern ring, and steel ball 5 is located at resetting spring 4
Between bolt 6.
The inner cavity of the steel ball 5 and handle 2 is slidably matched.
The diameter of the steel ball 5 is bigger than the diameter of resetting spring 4.
The stock 1 is round stock.
The stock of a diameter of 40mm, 2 length 115mm of handle can be selected in stock 1, and bolt 6 selects the high-strength spiral shell of 8.8 grades of 20mm
Bolt, length 70mm, cutter 3 select high-speed tool steel.
The operation principle of the utility model is as follows：
Nut to be cut is entangled using stock 1, is then screwed in bolt 6 using spanner, it will by the steel ball 5 for transmitting torque
Axial moment is transferred to 3 tail portion of cutter, until nut is cut off, then selects bolt 6, cutter 3 are in the work of resetting spring 4
It automatically resets under, completes the operation of cutting nut.
