As shown in FIG. 1 , an embodiment of the utility model provides a positioning pin disassembly tool, which specifically includes a connecting rod 1 , a disassembly handle 2 , a connecting sleeve 3 , a disassembly connector 4 and an auxiliary sleeve 5 .

Specifically, along the axial direction of the connecting rod 1, the disassembly handle 2 is installed on one end of the connecting rod 1, and the outer periphery of the other end of the connecting rod 1 is provided with a first external thread, and one end of the connecting sleeve 3 is provided with a first threaded hole, the connecting rod 1 is threadedly connected to the connecting sleeve 3, and the outer periphery of one end of the disassembly connecting head 4 is provided with a second external thread, and the other end of the connecting sleeve 3 is provided with a second threaded hole, the disassembly connecting head 4 is detachably connected to the connecting sleeve 3, and the outer periphery of the other end of the disassembly connecting head 4 is provided with a third external thread, and the third external thread is used for threaded connection with the locating pin; the auxiliary sleeve 5 is sleeved on the outer periphery of the connecting rod 1 and can slide along the axial direction of the connecting rod 1, and the disassembly handle 2 is provided with an abutting end face 21 on the side facing the disassembly connecting head 4, and the auxiliary sleeve 5 can abut against the abutting end face 21, and the outer periphery of the auxiliary sleeve 5 is fixedly provided with a push rod 51, and the push rod 51 is used to be connected to the power equipment.

In detail, when the positioning pin needs to be disassembled, the positioning pin disassembly tool is first assembled: the disassembly handle 2 is installed on one end of the connecting rod 1, and the connecting sleeve 3 is threadedly connected to the other end of the connecting rod 1. When the connecting sleeve 3 is connected to the connecting rod 1, the disassembly connector 4 is threadedly connected to the connecting sleeve 3, thereby completing the assembly of the positioning pin disassembly tool. After that, the other end of the disassembly connector 4 is threadedly connected to the positioning pin to be disassembled, so that the staff can pull out the positioning pin by holding the disassembly handle 2 and using manpower. When the specifications of the positioning pin change, it is only necessary to replace the disassembly connector 4 of the corresponding specifications. If the manpower is not enough to pull out the positioning pin, the auxiliary sleeve 5 is then sleeved on the connecting rod 1, and connected to the top rod 51 of the auxiliary sleeve 5 through the power equipment. The power equipment can drive the auxiliary sleeve 5 to press against the abutment end face 21 of the disassembly handle 2, so that the positioning pin can be easily removed with the help of the power equipment without causing damage to the positioning pin and the mechanical equipment.

Preferably, in this embodiment, the power device is a jack, and the movable end of the jack can abut against the push rod 51. In this way, the staff can easily and quickly take out the positioning pin by operating the jack.

Optionally, the disassembly handle 2 is provided with a third threaded hole, one end of the connecting rod 1 is provided with a fourth external thread, and the disassembly handle 2 is threadedly connected to the connecting rod 1. With such a configuration, the disassembly handle 2 can be quickly connected to the connecting rod 1, and the connection effect is good. Furthermore, after the disassembly handle 2 and the connecting rod 1 are threadedly connected in place, the disassembly handle 2 and the connecting rod 1 are welded and reinforced. With such a configuration, the connection strength between the connecting rod 1 and the disassembly handle 2 can be effectively improved, and the looseness between the disassembly handle 2 and the connecting rod 1 can be avoided when the locating pin is disassembled by the power equipment, thereby affecting the disassembly efficiency of the locating pin.

Optionally, a first anti-skid thread is provided on the outer periphery of the disassembly handle 2. By providing the first anti-skid thread on the outer periphery of the disassembly handle 2, the friction resistance between the hand of the worker and the disassembly handle 2 can be effectively increased. When the hand of the worker is stained with water or oil, the disassembly handle 2 can still be screwed well to avoid slipping, thereby ensuring the assembly efficiency of the positioning pin disassembly tool.

Optionally, the first threaded hole has a larger diameter than the second threaded hole. With this arrangement, the connecting rod 1 can be quickly connected to the connecting sleeve 3 and the connecting sleeve 3 to the disassembly connector 4 according to the difference in diameter between the first threaded hole and the second threaded hole.

Preferably, the outer contour of the connecting sleeve 3 is a regular hexagon. This arrangement makes it convenient for the staff to screw the connecting sleeve 3 when the connecting rod 1 is threadedly connected to the connecting sleeve 3. Of course, the outer periphery of the connecting sleeve 3 can also be provided with an anti-slip pattern structure to facilitate screwing.

Optionally, a plurality of push rods 51 are provided, and the plurality of push rods 51 are spaced apart along the circumference of the auxiliary sleeve 5. Further, the plurality of push rods 51 are welded to the outer periphery of the auxiliary sleeve 5. The plurality of push rods 51 are provided to facilitate connection with a power device.

Specifically, the disassembly connector 4 includes two integrally arranged docking parts 41, and a main body 42 arranged between the two docking parts 41 along the axial direction of the disassembly connector 4, one docking part 41 is provided with a second external thread, and the other docking part 41 is provided with a third external thread, and the shaft diameter of the main body 42 is larger than the shaft diameters of the two docking parts 41. Further, the outer periphery of the main body 42 is provided with a second anti-slip thread. In detail, the shaft diameter of the main body 42 is set to be larger than the shaft diameters of the two docking parts 41, so that the staff can screw the disassembly connector 4 more labor-savingly, and further providing the second anti-slip thread can avoid slipping when screwing the disassembly connector 4.

Furthermore, the second external thread and the third external thread have opposite rotation directions, thereby preventing the disassembly connector 4 and the connecting sleeve 3 from becoming loose when the disassembly connector 4 is threadedly connected to the positioning pin.

Optionally, in this embodiment, the materials of the connecting rod 1, the disassembly handle 2, the connecting sleeve 3, the disassembly connector 4 and the auxiliary sleeve 5 are all metal alloys.
