Detailed Description
The technical solution of the present invention will be further explained with reference to the drawings in the embodiments of the present invention.
The pin 8 is in a cylindrical shape and is of a hollow structure, an internal threaded hole 81 is machined inside the pin, countersunk holes 82 are obtained at two ends of the internal threaded hole 81 through flaring machining, and an oil storage ring 83 is machined on the outer side face of the cylinder of the pin 8.
A pin taking-out device comprises a handle 1, a middle rod 2, a sliding hammer 3, a connector 4, a hexagonal head screw 5 and a connecting sleeve 6,
the upper end of the handle 1 protrudes outwards along the radial direction to form a rotating handle 11, the handle 1 is arranged at the upper end of the middle rod 2, the sliding hammer 3 is sleeved on the middle rod 2, the connector 4 is of a sleeve structure and sleeved on the middle rod 2, the connector 4 is provided with external threads,
a small hole 62 is processed in the connecting sleeve 6, a big hole 61 is processed on the upper side of the small hole 62, the lower part of the hexagonal head screw 5 passes through the small hole 62 and clamps the head of the hexagonal head screw 5, the big hole 61 is used for accommodating the head of the hexagonal head screw 5,
the big hole 61 is processed with internal threads and is connected with the connector 4 by threads,
the lower end of the middle rod 2 is provided with a convex disc 21, the outer diameter of the convex disc 21 is larger than the inner aperture of the connector 4 and smaller than the inner aperture of the big hole 61,
the underside of the projecting disk 21 projects downward to form a hexagonal prism 22, which hexagonal prism 22 fits into a hexagonal hole in the head of the hexagonal-head screw 5.
Preferably, the sliding hammer 3 is provided with a handle 31.
Preferably, the handle 1 is in threaded connection with the upper end of the middle rod 2.
The using method comprises the following steps: as shown in fig. 1, the pin 8 has counter bores at both ends thereof, and the female screw hole 81 is formed therein so as not to directly touch the female screw hole 81 when both upper and lower surfaces thereof are hit with a hammer, thereby preventing the damage of the female screw hole 81.
