The device of the utility model has the advantages of simple structure and convenient operation and maintenance and causes no damage of dismounted parts.
Description
Technical field
The present invention relates to a kind of frock tool.
Background technology
In the main frame wheel process of maintenance aircraft, need the screw of dismounting wheel hub inwall 7 upper rails, generally adopt full dog point socket set cutter or the normal conventional extracting tool of a kind of being called " percussion tool " to dismantle.Because wheel use middle guide screw receives thermal shock repeatedly, it is locked to cause the threaded connection place to be prone to.In the unloading process, the full dog point socket set cutter skids easily, the damage head of screw; And " percussion tool " complicated operation needs two skilled workers co-operate simultaneously, wastes time and energy, and efficient is low, also damages the guide rail head of screw easily.Adopt this two kind tools dismounting,, then can cause the dismounting difficulty, even can't dismantle, finally have to adopt the method for spark machined to be removed if damaged head of screw.Therefore,, prevent that the guide rail screw from crossing poly-injury and causing waste, be badly in need of improving the method that adopts conventional instrument dismounting guide rail screw in order to increase work efficiency.
Summary of the invention
Cause waste for overcoming the perhaps easy damaged head of screw that exists in the prior art, perhaps complicated operation and inefficient deficiency the present invention proposes a kind of airplane wheel guide rail screw disassembling device.
The present invention includes drill chuck, dwang, adjusting rod, fixed bar and cushion block.The connection tenon of dwang is packed in the connecting hole of drill chuck tail end end face, and interference engagement between the two; The connecting rod of regulating is packed in the connecting hole of dwang one end end face, and matched in clearance between the two; The connecting rod of fixed bar is packed into and is regulated in the threaded connection hole of an end end face; The contiguous block at one end end face center of cushion block embeds in the blind hole at fixed bar one end end face center, and interference engagement between the two.
The connection tenon of described dwang is taper; The connecting hole of drill chuck also is taper.One radial direction through hole is arranged on the excircle of dwang.
Because the technical scheme that the present invention taked can be clamped in the guide rail head of screw groove full dog point socket set cutter head of stripping attachment one end through the total length of screw connection point adjusting rod portion, the cushion block of the other end tightly withstands on the wheel hub inwall just.When turning the stripping attachment knockout screw, because driver bit is stuck, therefore can from the head of screw groove, not skid like this, screw be easy to unscrew, and also can not damage head of screw.After screw is unscrewed, just can pull down smoothly.The characteristics of this stripping attachment are: according to the columnar structured characteristics of wheel hub wall; Utilize wheel hub inwall confined spaces, the method through adjustment stripping attachment length tightly is stuck in driver bit in the guide rail head of screw groove; Stoped driver bit to skid, made unloading process easy more smooth and easy.That the present invention has is simple in structure, easy to operate, be convenient to safeguard, and the low characteristics of use cost, and the part that is disassembled is not had any damage.

The specific embodiment
Present embodiment is the stripping attachment of the guide rail screw on a kind of main frame wheel 2606671-2 wheel hub that is used to dismantle the B737 series aircraft.
Present embodiment comprises full dog point socket set cutter head 1, drill chuck 2, dwang 3, adjusting rod 4, fixed bar 5 and cushion block 6.Drill chuck 2, dwang 3, adjusting rod 4 and fixed bar 5 are circular rod member.Wherein:
The standard drill chuck that drill chuck 2 adopts on the small-sized bench drill; There is the blind hole that has a little tapering at tail end end face center at this drill chuck; This blind hole has formed the connecting hole of drill chuck 2, and the tapering of this connecting hole and aperture are all with tapering that is connected tenon and external diameter on the dwang 3.
One end end face of dwang 3 has the connection tenon of axial protrusion, and this connects tenon and cooperates with the tapered blind hole at drill chuck 2 tail end end face centers, is used for dwang 3 is connected with drill chuck 2; There is blind hole at the end face center of dwang 3 other ends, and this blind hole has formed the connecting hole of dwang 3, and the aperture of this connecting hole is with the external diameter of the connecting rod on the adjusting rod 4.On the excircle of dwang 3, a radial direction through hole is arranged, this through hole is arm of force hole, is used for when using present embodiment, screws or loosens stripping attachment through removing instruments such as tube.
The excircle of adjusting rod 4 is stepped, is positioned at the connecting rod of the reduced diameter section of this adjusting rod one end for this adjusting rod, is used for adjusting rod 4 is connected with dwang 3; There is tapped blind hole at the end face center of the enlarged diameter section of adjusting rod, and this tapped blind hole has formed the threaded connection hole of adjusting rod 4, and the aperture of this threaded connection hole is with the external diameter of the whorl brace rod on the fixed bar 5.
The excircle of fixed bar 5 also is stepped, and the reduced diameter section that is positioned at this fixed bar one end is a threaded rod, has formed the connecting rod of fixed bar, is used for fixed bar 5 is connected with adjusting rod 4; There is blind hole at end face center at the enlarged diameter section of fixed bar 5, and this blind hole has formed the connecting hole of fixed bar 5, and the aperture of this connecting hole is with the external diameter of the connecting rod on the cushion block 6.
Cushion block 6 is a cone, has along the contiguous block of the axial protrusion of cushion block 6 at these cushion block 6 one end end face centers, is used for cushion block 6 is connected with fixed bar 5.The hardness of cushion block material is suitable with wheel hub inwall 7 material hardnesses, prevents to push up when stripping attachment from using to hinder wheel hub inwall 7.
In the present embodiment, wheel hub is a steel material, so drill chuck 2, dwang 3, adjusting rod 4 and fixed bar 5 are all selected steel material for use.
The taper connection tenon of dwang 3 is packed in the tapered blind hole of drill chuck 2 tail end end faces, and make interference engagement between the two.The connecting rod of adjusting rod 4 is packed in the blind hole of dwang 3 one end end faces, and make matched in clearance between the two.The connecting rod of fixed bar 5 is packed in the tapped blind hole of adjusting rod 4 one end end faces.The contiguous block at one end end face center of cushion block 6 is embedded in the blind hole at fixed bar 5 one end end face centers, and make interference engagement between the two.
When [0020] using, the full dog point socket set cutter head is clamped with drill chuck; Turn the screw thread of adjusting rod 4 and fixed bar 5 junctions; The total length of adjustment stripping attachment airplane wheel guide rail screw 9; Make airplane wheel guide rail screw disassembling device 9 can put into the wheel hub chamber just; Aim at and want the position of knockout screw, and the full dog point socket set cutter head of airplane wheel guide rail screw disassembling device 9 one ends is inserted in the guide rail screw 8 respective screws grooves, the cushion block of airplane wheel guide rail screw disassembling device 9 other ends tightly withstands on the wheel hub inwall 7.Through rotation dwang 3, drive full dog point socket set cutter head and drill chuck and rotate together, make guide rail screw 8 loosening, and regulate the total length of airplane wheel guide rail screw disassembling device 9, guide rail screw 8 is turned gradually and finally pulls down.
