Detailed Description

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

The technical scheme is explained in detail by combining the attached drawings, the dismounting tool for the magnetic plug comprises a rotating shaft 1, a sleeve 2, a clamping cylinder 3 and a grabbing mechanism 4 for grabbing the magnetic plug, wherein the sleeve is connected with the clamping cylinder to enable the sleeve to be communicated with the inside of the clamping cylinder, one end of the rotating shaft penetrates through the inside of the sleeve and extends into the inside of the clamping cylinder and is connected with the grabbing mechanism in the clamping cylinder, the magnetic plug is separated from a clamping groove through the grabbing mechanism and then is rotated to pull out the magnetic plug when in use, concretely, the grabbing mechanism comprises a push head 6 and an elastic chuck 7, the elastic chuck can select materials with better elasticity such as nylon, one end of the push head is connected with the rotating shaft, the push head can be detachably connected with the rotating shaft in a key connection mode or the push head and the elastic chuck can be directly and fixedly connected, the other end of the push head is connected with the elastic chuck, the outer surface of the push head is provided with external threads matched, the end part of the sleeve is of a gradually-necking structure, the end face of the annular boss can be attached to the end part of the sleeve, the caliber of the port of the sleeve is larger than or equal to the diameter of an upper magnetic plug cap of the magnetic plug, the outer surface of the sleeve is provided with a transverse groove I8 which sequentially penetrates through the annular boss from one side surface to the other side surface of the sleeve, the outer surface of the annular boss is provided with a transverse groove II 9 which penetrates through from one side surface to the other side surface of the sleeve, when a grasping mechanism needs to grasp the magnetic plug, a worker holds the sleeve by hand, the other hand holds the rotating shaft, then the rotating shaft is rotated, in order to facilitate manual operation, the surface of the sleeve is provided with a holding cylinder 12, the rotating shaft is provided with a handle 13, the manual holding and rotating of the rotating shaft are facilitated, when the sleeve is manually held, the holding cylinder penetrates through a pipeline arranged near a, the magnetic blocking cap extends into the annular boss from the end part of the sleeve, then the rotating shaft is rotated, the rotating shaft drives the push head to rotate, the push head is fed forwards, the push head pushes the elastic chuck to move towards the direction of the magnetic blocking cap, when the elastic chuck moves, the annular boss is propped against by the necking structure at the end part of the sleeve, then the feeding cannot be carried out, further elastic deformation is generated to clamp the magnetic blocking cap, then the rotating shaft is rotated and the sleeve is fed downwards, the push head pushes the elastic chuck, the end part of the elastic chuck is contacted with the magnetic blocking cap, then downward pressure is applied to the magnetic blocking cap, meanwhile, the downward pressure applied to the magnetic blocking cap by the downward movement of the sleeve is combined, the magnetic blocking cap moves downwards, the fixing pin is separated from the clamping groove, then the sleeve is rotated to drive the magnetic blocking cap to rotate out of the transverse groove of the L-shaped groove, then the sleeve is pulled to separate the magnetic blocking cap from the L-shaped groove, and the disassembly, after the magnetic plug is separated from the channel, the rotating shaft is reversely rotated to enable the push head to feed towards the direction of the holding cylinder, the pressure of the push head on the elastic chuck is gradually reduced, the elastic chuck resets, the necking structure at the end part of the sleeve does not abut against the annular boss, after the shape of the annular boss is reduced, the magnetic plug falls out of the sleeve, and finally the disassembly of the magnetic plug is completed.

When the elastic chuck is pushed by the pushing head, and simultaneously the annular boss is supported by the necking structure at the end part of the sleeve, when the elastic chuck and the pushing head are integrally deformed, in order to prevent the notch of the transverse groove I and the notch of the transverse groove II from being too concentrated in stress and generate the phenomenon of notch tearing, the cross section at the end of the transverse groove I and the cross section of the transverse groove II are both set to be arc 10, the stress concentration phenomenon is effectively shared through the arc, the notch tearing is prevented, an anti-abrasion lining 11 is arranged between the pushing head and the elastic chuck, the friction between the pushing head and the elastic chuck in the rotating process is effectively reduced, a groove 14 is arranged on the side surface of the elastic chuck, the end part of a screw 15 arranged on the side surface of the clamping cylinder extends into the groove, the feeding position of the elastic chuck is effectively limited through the limit of the screw, and the pushing head is further prevented from sliding out of the internal thread of, the wedge-shaped clamping head is annularly arranged on the periphery of the end part of the clamping cylinder and is connected with the end part of the clamping cylinder through a connecting screw.

The structure of the gradual throat of telescopic tip comprises wedge dop 5 and connecting screw, and the wedge dop ring is established in a week of card section of thick bamboo tip, and the wedge dop is connected with a card section of thick bamboo tip through connecting screw, through setting up the structure of detachable throat, has made things convenient for the production and the equipment of whole equipment.
