Abstract
The utility model relates to a kind of extracting tool, the extracting tool particularly during a kind of leading screw locking.Comprise axle sleeve, the first keyway of axle sleeve inside, rotary handle, axle sleeve inside diameter is identical with leading screw diameter, and the first keyway and leading screw on leading screw and motor transmit the second keyway be connected and coordinate.Utilize key to carry out the transmission of power, change traditional pipe wrench and act directly on force way on axle, thus avoid, to the infringement of leading screw, effectively protecting leading screw, and force transmission effect is also good than pipe wrench, effectively avoid skidding, protection operating personnel safety.
Description
Technical field
The utility model relates to a kind of extracting tool, the extracting tool particularly during a kind of leading screw locking.
Background technology
Lead screw transmission is widely used in the every field of machinery industry, also applies to some extent in the width adjusting and gap adjustment of the 3# cross shearing unit scrap cutter of Shanxi Taigang Stainless Steel Co., Ltd.In use usually there will be the phenomenon of locking between leading screw and screw.In the process of removing, be in machine intimate because screw leads to into, normally with pipe wrench forced rotating leading screw, itself and screw are thrown off, this mode easily causes the damage of leading screw, and the leading screw that finally can only more renew, causes significant wastage.And usually need great external force just can unclamp when dismantling, also there will be skidding with pipe wrench dismounting, unexpected power of unloading also can jeopardize the safety of operating personnel.
Summary of the invention
Technical problem to be solved in the utility model is: when how to solve locking between leading screw and screw, is not easy dismounting, and the unexpected power of unloading of possibility also can jeopardize the safety problem of operating personnel.
The technical scheme that the utility model adopts is: extracting tool during a kind of leading screw locking, comprise axle sleeve, the first keyway of axle sleeve inside, rotary handle, axle sleeve inside diameter is identical with leading screw diameter, and the first keyway and leading screw on leading screw and motor transmit the second keyway be connected and coordinate.
As a kind of preferred embodiment: rotary handle has 4, rotary handle becomes column to be evenly distributed on axle sleeve normal section circle excircle.
As a kind of preferred embodiment: rotary handle is bolted outside axle sleeve, be install handle at use instrument, do not use during instrument and take off handle, instrument placement space can be saved.
The beneficial effects of the utility model are: utilize key to carry out the transmission of power, change traditional pipe wrench and act directly on force way on axle, thus avoid, to the infringement of leading screw, effectively protecting leading screw.And force transmission effect is also good than pipe wrench, effectively avoid skidding, protection operating personnel safety.

Detailed description of the invention
As shown in Figure 1, the width adjusting of the 3# cross shearing unit scrap cutter of the existing leading screw of Shanxi Taigang Stainless Steel Co., Ltd, transmission portion is the lead screw shaft of a Φ 50mm, axle there is second keyway of 14mm be connected with motor, leading screw drives screw to rotate the width regulating and cut, certainly between leading screw and screw during locking, the the second keyway forced rotating leading screw exposed after motor disassembling clamped by usual employing pipe wrench makes itself and screw throw off, the easy like this damage causing leading screw, and also there will be skidding with pipe wrench dismounting, unexpected power of unloading also can jeopardize the safety of operating personnel.
The utility model instrument passes through at an external diameter Φ 100mm, internal diameter Φ 50mm length is first keyway of the inside milling 14mm of the steel pipe (axle sleeve) of 100mm, lap welding connects 3 to 4 reinforcing bars as rotary handle outside, when dismounting, this instrument is enclosed within the position of the second keyway on leading screw together with key, rotates on the rotary handle of outer ring with steel pipe and leading screw can be driven to rotate.This specific purpose tool is utilize key to carry out the transmission of power in dismounting, changes traditional pipe wrench and acts directly on force way on axle, thus avoid, to the infringement of leading screw, effectively protecting leading screw.And force transmission effect is also good than pipe wrench, effectively avoid skidding, protection operating personnel safety.In order to easy to carry, steel bar end as rotary handle is made into bolt shape, and axle sleeve normal section circle excircle evenly stamps several screw coordinated with bolt, is install handle at use instrument, do not use during instrument and take off handle, instrument placement space can be saved.
Claims (3)
1. extracting tool during leading screw locking, is characterized in that: comprise axle sleeve, the first keyway of axle sleeve inside, rotary handle, axle sleeve inside diameter is identical with leading screw diameter, and the first keyway and leading screw on leading screw and motor transmit the second keyway be connected and coordinate.
2. extracting tool during a kind of leading screw locking according to claim 1, is characterized in that: rotary handle has 4, and rotary handle becomes column to be evenly distributed on axle sleeve normal section circle excircle.
