Abstract
The invention belongs to the assembly technology and relates to a bolt disassembly tool. The bolt disassembly tool is characterized by being composed of a clamping body and a locking nut [4]. The clamping body is composed of a handle [1], a screw [2] and an elastic three-claw head [3], the right end face of the handle [1] is coaxially integrated with the left end of the screw [2] in connection mode, the right end of the screw [2] is integrated with the root portion of each clamping claw of the three-claw head [3] in connection mode, and the locking nut [4] is screwed on the screw [2] of a clamping body. The bolt disassembly tool can firmly clamp a bolt to be disassembled, so that bolt disassembly work can be conveniently conducted, and unnecessary damage to the equipment caused by welding of a process rod is avoided.
Description
Technical field
The invention belongs to mounting technology, relate to a kind of bolt disassembling tool.
Background technology
The dismounting that bolt is often used in machinery assembling field can't be dismantled after outer six square toes of the bolt that has or the interior hexagonal hole wearing and tearing, need on bolt, just can carry out the bolt decomposition by the welding procedure bar.Possibly cause unnecessary harm to equipment during welding.The narrow and small occasion in some space can't be welded, and the dismounting of bolt just becomes the difficult problem of maintenance of equipment.
Summary of the invention
The objective of the invention is: a kind of bolt disassembling tool is provided, so that carry out the dismantlement work of bolt easily.
Technical scheme of the present invention is: a kind of bolt disassembling tool is characterized in that: it is made up of cramping body and locking nut 4, and cramping body is made up of handle 1, screw rod 2 and elasticity three-jaw chuck 3; On the external cylindrical surface of handle 1 annular knurl is arranged; The right side of handle 1 is connected to integral body with the coaxial integral body that is connected to of the left end of screw rod 2, the root of the right-hand member of screw rod 2 and three-jaw chuck 3 each jaw, and 3 jaws of three-jaw chuck 3 are uniformly distributed along the circumference; The angle of the length direction of each jaw and the axis of cramping body=15 °～45 °; The outer surface 3a of 3 jaws is positioned on the same taper seat, and this taper seat is coaxial with screw rod 2, and teeth 3b is arranged on the inner surface of 3 jaws; Locking nut 4 is cylinders that have internal thread; Locking nut 4 is screwed on the screw rod 2 of cramping body; Right output port at locking nut 4 has an inner conical surface, and the cone angle of this conical surface is 2 α, when 3 jaws are clamped bolt 5 to be removed; The outer surface 3a of this conical surface and 3 jaws fits, and the external screw thread of the internal thread of locking nut 4 and screw rod 2 is left-hand thread screw threads.
Advantage of the present invention is: clamping bolt to be removed securely, thus can carry out the dismantlement work of bolt easily, avoided causing unnecessary harm because of welding procedure pole pair equipment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Explain further details in the face of the present invention down.Referring to Fig. 1, a kind of bolt disassembling tool is characterized in that: it is made up of cramping body and locking nut 4; Cramping body is made up of handle 1, screw rod 2 and elasticity three-jaw chuck 3, on the external cylindrical surface of handle 1 annular knurl is arranged, the right side of handle 1 and the coaxial integral body that is connected to of the left end of screw rod 2; The root of the right-hand member of screw rod 2 and three-jaw chuck 3 each jaw is connected to integral body; 3 jaws of three-jaw chuck 3 are uniformly distributed along the circumference, angle=15 of the length direction of each jaw and the axis of cramping body °～45 °, and the outer surface 3a of 3 jaws is positioned on the same taper seat; This taper seat is coaxial with screw rod 2, and teeth 3b is arranged on the inner surface of 3 jaws; Locking nut 4 is cylinders that have internal thread; Locking nut 4 is screwed on the screw rod 2 of cramping body; Right output port at locking nut 4 has an inner conical surface, and the cone angle of this conical surface is 2a, when 3 jaws are clamped bolt 5 to be removed; The outer surface 3a of this conical surface and 3 jaws fits, and the external screw thread of the internal thread of locking nut 4 and screw rod 2 is left-hand thread screw threads.
In order to increase turning moment, in-line or cross assister bar are arranged on handle 1.
Operation principle of the present invention is: at first 3 jaws with the three-jaw chuck that is uniformly distributed along the circumference 3 are stuck on the bolt 5 to be removed; Then locking nut 4 is rotated counterclockwise; Make its direction motion to bolt 5 to be removed; The outer conical surface of 3 jaws of inner conical surface extruding of locking nut 4 right output port is tightened up jaw bolt 5 to be removed is clamped.Be rotated counterclockwise handle 1 then, bolt 5 to be removed is disassembled.Because the screw thread of screw rod 2 and locking nut 4 is left-hand thread screw threads, and on the inner surface of 3 jaws teeth is arranged, so bolt to be removed 5 can not get loose in unloading process.
One embodiment of the present of invention, angle=30 of the length direction of each jaw of three-jaw chuck 3 and the axis of cramping body °.The cone angle of the inner conical surface of the right output port of locking nut is processed as 60 °.
