Detailed Description
The invention will be further described with reference to the accompanying figures 1-4 and the specific embodiments.
An auxiliary device for disassembling a positioning pin at least comprises a supporting inner body 4 and a supporting outer body 2, wherein the supporting inner body 4 is tubular, a through hole 3 for the positioning pin 1 to pass through is axially formed in the central position of the supporting inner body 4, the outer wall of the supporting inner body 4 is divided into an outer thread section and a lower supporting section 11 from top to bottom, and an outer thread 9 is formed in the outer thread section; the supporting outer body 2 is in a sleeve shape, a sleeve hole 13 for the positioning pin 1 to penetrate through is axially arranged at the central position of the supporting outer body 2, the sleeve hole 13 is divided into an upper supporting section and an inner thread section from top to bottom, the upper supporting section is a necking structure 8 formed by extending the diameter of the sleeve hole 13 inwards in the radial direction, and the inner thread section is provided with an internal thread 7 matched with the external thread section 9 of the supporting inner body 4; the internal thread section 7 of the support outer body 2 is screwed with the external thread section 9 of the support inner body 4.
The specific implementation mode is as follows: the positioning pin 1 is vertically fixed on the plane 5, the through hole 3 of the auxiliary tool is vertically installed by sleeving the positioning pin 1, the height of the supporting outer body 2 is adjusted by rotating, the head thread of the positioning pin 1 is exposed out of the necking structure 8, the nut 6 is in threaded connection with the positioning pin 1, the top surface 10 is in contact with the bottom surface of the nut to support the nut 6, the commonly used positioning pin 1 adopts right-handed threads, the nut 6 needs to be rotated clockwise during dismounting, the positioning pin 1 is driven to do axial motion away from the plane 5, the positioning pin 1 is gradually pulled out of the plane 5, the relative height of the nut 6 and the plane 5 is required to be unchanged during dismounting, the bottom surface of the nut 6 is in contact with the top surface 10 to extrude to generate friction force on the supporting outer body 2, the rotation direction of the external threads 9 of the supporting inner body 4 is opposite to that of the threads of the positioning pin can offset the friction force, and the height of the supporting nut 6 of the auxiliary tool is kept unchanged. Furthermore, the use of spacers between the bottom and top surfaces 10 of the nut is extended.
Implement the utility model discloses afterwards, obviously just realized: as long as possess the utility model discloses, alright be suitable for and dismantle various sizes of locating pin 1, this has just created the condition for realizing safe swift, raise the efficiency.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
