Specific implementation mode

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

Technical solution used by the utility model is：As shown in Figures 1 to 5, a kind of bolt fracture withdrawing device, packet Include fluted drill 1, guide section 2 and the spanner 3 for making guide section 2 rotate, the outer diameter of the fluted drill 1 and the internal diameter phase of break bolt 10 Matching, the guide section 2 are a cube, and four inclines and the 5 hole internal diameter of break bolt of the guide section 2 are mutually inscribed, described 2 top of guide section is provided with screw thread 4, and 4 outside of the screw thread is configured with guide blot 5, one end of the spanner 3 and guide blot 5 are used cooperatively, and the other end of the spanner 3 is provided with magnet 6.

In this application, the effect of fluted drill 1 is to drill through 10 central part of break bolt, and the effect of magnet 6 is will to break Split clast in 10 hole of bolt to take out, then guide section 2 tapped in 10 hole of break bolt, make four inclines of guide section 2 with 10 hole internal diameter of break bolt connects, and so that bolt bore is generated local deformation to hold guide section 2 tightly by size interference volume, then lead to It crosses 3 turn of spanner and applies the torque opposite with 10 screw-in direction of break bolt to guide section 2, loosen break bolt 10 to reach Effect.

Preferable scheme is that 5 lower section of the guide blot is arranged with washer 7 and backing plate 8, the washer 7 outside guide section 2 It is arranged above backing plate 8,8 both sides of the backing plate are provided with adjusting bolt 9.

By the setting of washer 7 and backing plate 8, the cushion effect between 10 top of break bolt and guide section 2 is increased, is reduced Frictional force between break bolt 10 and guide section 2, extends the service life of guide section 2；By adjusting bolt 9 so that leading Entering the depth of 10 endoporus of break bolt to section 2 becomes adjustable, is applicable to the taking-up of the break bolt 10 of different lengths.

Preferable scheme is that four inclines of the guide section 2 are interference fitted with 10 centre bore of break bolt, pass through Interference fit is to generate interference fit power, then by 3 turn of spanner is that guide section 2 applies and 10 screw-in direction phase of break bolt Anti- torque loosens 10 effect of break bolt to reach, break bolt 10 is made to be screwed out out of threaded hole.

Preferable scheme is that four sides of the guide section 2 vertical connection between any two, due to by guide section 2 four Side is set as vertical connection between any two, to maintain four sides of guide section 2 and 10 endoporus touching position of break bolt Angle is tip shape, to ensure that guide section 2 is preferably interference fitted with 10 hole of break bolt.

Preferable scheme is that one end of the guide section 2 and 10 endoporus bottom contact position of break bolt is shrink mouth shape, it is described 2 bottom four of guide section is being 3 ° -6 ° with angle when top four；This kind design makes preferably 10 hole of break bolt of guide section 2, energy It is enough preferably to be positioned.

Preferable scheme is that the diameter of one end that the spanner 3 is connected with magnet 6 is less than the straight of the break bolt 10 Magnet 6 can be just put into 10 hole of break bolt by diameter since the diameter of magnet 6 is less than the diameter of break bolt 10, into And smoothly bolt clast is taken out.

Because there are many in the actual production process, large-scale plant can there is a phenomenon where bolt fractures, and these large size dresses It sets complex, there is various small parts above, and the method for not easily passing through device overturning will be inside 10 hole of break bolt Clast take out, so being taken out extra clast using magnet 6, the method is simple and fast, and debris removal effect is preferable.

The operation principle of the utility model is to drill through bolt-center part by fluted drill, pass through the magnetic of spanner one end Iron takes out the clast in break bolt hole, then guide section tapped in break bolt hole, make four inclines of guide section with Break bolt hole internal diameter connects, and so that bolt bore is generated local deformation to hold guide section tightly by size interference volume, then pass through Spanner turn applies the torque opposite with break bolt screw-in direction to guide section, to achieve the effect that loosen break bolt, Break bolt is set to be screwed out out of threaded hole, the utility model is simple in structure, can be processed manually, simple and efficient to handle.

It is the preferred embodiment of the utility model above, does not impose any limitation on the present invention, Every foundation the technical essence of the utility model any simple modification, equivalent change and modification made to the above embodiment, Belong in the range of utility model technical solution.
