Description

Technical Field

[0001] The utility model relates to the technical field of cone pin disassembly tools, in particular to a cone pin disassembly device. Background Art

[0002] The box of the packaging unit is generally connected by tapered pins between the transmission shaft and the gear, the transmission shaft and the rocker arm, and the transmission shaft and the cam, which plays the role of power transmission and positioning.

[0003] The current method of disassembling the taper pin is to use a hand hammer and a pin driver to hit the taper pin. Due to the narrow space and insufficient operating space, it is difficult for the pin driver to align with the positioning pin, that is, the two axes are not coaxial, and radial force is generated when hitting the taper pin, which affects the disassembly effect. It is difficult for the hand hammer to effectively hit the pin driver. In addition, when hitting, the transmission shaft will produce elastic and plastic deformation, offsetting part of the knocking force and buffering the impact force applied to the taper pin. These two factors together seriously affect the pinning effect. After multiple knocks, the positioning pin aperture is easily deformed, which increases the difficulty of disassembling the taper pin.
