Description
Technical field
The present invention relates to the technical field of Bolt dismantling appurtenance, in particular to a kind of expansion bolt cleaner.
Background technology
Industry and sphere of life, expansion bolt are a kind of very common parts, can be set at the position that is difficult to put forth effort by
Power hanging point, the field of application are extremely wide.But in some cases, when expansion bolt setup error, is but extremely difficult to clean off,
Expansion bolt corrosion or need to change position again in some cases, the expansion bolt originally installed just needs to clean up.Often
Method is to pound mounted expansion bolt using sledgehammer curved to be left in place or pounded into ground or metope.Also
Some situations be the part that expansion bolt is exposed using angle grinder polish flat make it with ground or metope patch and, keep away
Exempt to influence miscellaneous part.No matter which kind of method used, the processing to expansion bolt is all extremely cumbersome to be taken time and effort, and sometimes can also
The metope near expansion bolt or ground are destroyed, is lost more than gain.
Someone devises a kind of device for clearing up corrosion bolt, Patent No. " CN103977971A " it is entitled " a kind of right
The Chinese utility model patent of the cleaning tool of corrosion bolt " describes a kind of instrument of dedicated cleaning corrosion bolt, this is clear
Science and engineering tool is cylindrical structure, the through hole being coaxial therewith along the axial setting of cylinder, the position in the axial direction of cylindrical body outer wall
The circumferentially distributed ratchet gear teeth are installed, set the cleaning sword of intermittent screw thread formula on the inner walls of the via, between adjacent two cleaning swords
If axially extending chip-removal hole.One end of through hole is set to inner chamfer structure, the other end is set to outer chamfer structure.Outside cylinder
Two annular grooves are set on wall, two annular grooves are using plane where the ratchet gear teeth circumferentially as the plane of symmetry, axially symmetric disposition.Should
Patent is cleaned up by the way that the bolt of corrosion directly is cut into chip using cleaning sword with this, is avoided using sledgehammer or angle
Cleaning of the grinding machine to corrosion bolt, simple and fast, will not destroy the structure on corrosion bolt periphery.
But if the cleaner described using the patent is removed expansion bolt and there are problems that：1st, expansion bolt is outer
Sleeve forms irregular shape after stress extruding, is difficult to clean off machining away using the cleaner；2nd, it is clear using this
After managing device cutting expansion bolt, the screw portion on expansion bolt can be also cleaned out, it is impossible to which secondary use, causes the wave of resource
Take；3rd, the cleaner needs to clear up sword well using cutting edge, virtually increases the cost of whole cleaner, is unfavorable for promoting and answers
With.

Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1~7, the expansion bolt cleaner of the present embodiment includes hollow cylindrical sleeve 1, is equipped with sleeve 1
A piece mandril 2 being connected with its screw-driven, axial thrust can be applied to the screw rod 13 of expansion bolt by screwing mandril 2, sleeve 1
Fixed disk 3 is installed on axial end portion, the first through hole 14 connected with sleeve 1 of perforation is offered at the center of fixed disk 3, is pushed up
Bar 2 is arranged in the first through hole 14 of sleeve 1 and fixed disk 3 axially translatablely, and fixed disk 3, sleeve 1 and mandril 2 are coaxial
Set.For the ease of screwing mandril 2, the present embodiment is provided with the force rod 11 vertical with its axis in the end of mandril 2, rotates
Force rod 11, which makes it be rotated around 2 axis of mandril, can screw mandril 2, mandril 2 is advanced or is retreated.
Fixed disk 3 is provided with the chuck of the outer sleeve 12 for fixed expansion bolt backwards to the side of sleeve 1.Chuck is three
Dog chuck structure, including three claws 4, fixed disk 3 is hollow, and fixed disk 3 offers three radially backwards to the side of sleeve 1
The card slot 5 of arrangement, card slot 5 are symmetrically arranged in the card of fixed disk 3 in a manner of 120 ° of interval two-by-two, and claw 4 is in fixed disk 3
It is fixed on axial direction in card slot 5, radially direction is moved.
Claw 4 can move in radial directions mainly to be driven by the disk gear 6 being arranged in fixed disk 3.Such as Fig. 4
It is shown, the driving rack 9 of equidistant disc spring type is provided with the side card of disk gear 6, is set on the periphery of disk gear 6 with teeth
Structure.Disk gear 6 and fixed disk 3 are coaxial, and the center offers second through hole corresponding with the first through hole 14 on fixed disk 3
15, disk gear 6 can be rotatable around its axis, and the second through hole 15 is socketed on the outside of the dome of first through hole 14.
As shown in Fig. 5~7, claw 4 is T-shaped structure, and major part one end is stuck in card slot 5, claw 4 towards fixed disk 3 one
Feed rack 8 corresponding with driving rack 9 is provided with the end face of face, that is, major part side, feed rack 8 is driven with driving rack 9
It is connected, rotating disk gear 6 can drive claw 4 to be moved in the radial direction along fixed disk 3.Claw 4 is backwards to feed rack 8
The end set of side have the arc cutter formula cat's paw 10 of bending, the outer sleeve of expansion bolt can be firmly firmly grasped by cat's paw 10
12。
As shown in figure 3, being also equipped with shaft gear 7 in fixed disk 3, shaft gear 7 is used for drive disk gear 6 and turns around its axis
Dynamic, shaft gear 7 is column construction, and the rack structure of sidepiece and 6 sidepiece of disk gear is sequentially connected, shaft gear 7 and 6 weeks teeth of disk gear
Intermeshing transmission, 7 axis of shaft gear are parallel with 6 axis of disk gear.Shaft gear 7 also has three respectively with 120 ° of interval two-by-two
Mode is installed on fixed disk 3 in the card of 4 side of claw, and wherein shaft gear 7 is arranged between two adjacent claws 4,
Fixed disk 3 between its axis and two adjacent claws 4 intersects vertically.Set three shaft gears 7 just can engage disk gear 6
In fixed disk 3, stable gear transmission structure is formed.
As shown in figs. 8-10, in actual use, first the nut of expansion bolt is exited, and the packing ring of expansion bolt is taken
Under, expansion bolt cleaner mandril 2 is then fallen back on appropriate location, is enable in the fully-inserted pawl disk of expansion bolt head, screw rod 13
It can extend into first through hole 14, so that cat's paw 10 is close to metope, then revolved with wrench rotation 7 drive disk gear 6 of shaft gear
Turn driving claw 4 radially to move, make the outer sleeve 12 of the tight expansion bolt of 10 pawl of cat's paw, then rotate force rod 11, make top
The end of bar 2 presses closer 13 end of screw rod of expansion bolt, at this moment, screws mandril 2 and applies inside thrust, expanding screw to screw rod 13
The expansion rod of bolt is promoted to bottom, and the outer sleeve bottom of expansion bolt just loses expansive force, and cat's paw 10 is in the active force of mandril 2
The reverse reaction force of lower generation outwards pulls expansion bolt outer sleeve 12, and expansion bolt outer sleeve 12 is gradual under a stretching force
It is straightened and loses expansive force, screw rod 13 and expansion bolt outer sleeve 12 continues counter motion, 12 more parts of expansion bolt outer sleeve
It is straightened, expansive force is less and less, until completely disengaging screw rod 13, expansion bolt outer sleeve 12 is taken out, screw rod 13 is from expansive force
Influence also can quickly be taken out out of hole, complete the scale removal process of expansion bolt.And after taking out, dilating screw 13 and outer sleeve 12
It can also be combined, reuse.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent defines.
