Description

Technical Field

[0001] The utility model relates to the technical field of connecting pin disassembly and assembly, in particular to a coil connecting pin disassembly and assembly tool. Background Art

[0002] Pins are standard parts that can be used as positioning parts to determine the relative positions between parts; they can also play a connecting role to transmit lateral forces or torques; or as overload cut-off parts in safety devices. Pins can be divided into cylindrical pins, conical pins, and special-shaped pins. Cylindrical pins are fixed in the hole by a small amount of interference, and the size, shape, and surface roughness of the pin hole are required to be high. The pin hole must be reamed before assembly. Usually, the two holes of the connected parts should be drilled and reamed at the same time, and the roughness of the hole wall should not exceed Ra0.6μm. During assembly, apply lubricating oil on the pin and drive the pin into the hole with a copper rod.

[0003] The existing patent publication number is CN215701382U, which discloses a pin pulling device. The pin pulling device described in the utility model includes a connecting rod, a pin pulling head and a pin shaft screwing head; the pin pulling head and the pin shaft screwing head are respectively connected to the connecting rod, and the pin pulling head is suitable for being detachably connected to the pin shaft to form a match in the axial direction of the pin shaft; the pin shaft screwing head is suitable for being detachably connected to the pin shaft to form a match in the circumferential direction of the pin shaft. Before pulling out the pin, the pin shaft screwing head is detachably connected to the pin shaft to form a force match in the circumferential direction of the pin shaft, and the pin shaft can be screwed by the pin shaft screwing head to make the pin shaft loose between the pin shaft and the sleeve, and then the pin shaft is pulled out by the pin pulling head to avoid the pin shaft and the sleeve from being stuck, and to avoid the pin shaft being broken due to forced pulling out when the pin shaft is stuck, so that pulling out the pin shaft is easier. The pin shaft screwing head and the pin pulling head are integrated on the connecting rod at the same time, which can also be convenient for storage to avoid the scattering and loss of tools.

[0004] The existing coil surface needs to use a connecting pin, which is time-consuming and laborious for workers to install and remove, and is easy to damage the connecting pin and the coil body. Therefore, we propose a coil connecting pin disassembly tool to solve the above-mentioned problems. Utility Model Content
