Abstract

The invention discloses a chain dismounting device which comprises a base, a threaded rod and a cam, wherein the threaded rod is in threaded connection with the base; the cam is positioned below the threaded rod; the base comprises a C type base, a vertical plate and a base plate; the C type base comprises an upper supporting plate, a side plate and a bottom plate; a threaded through hole matched with the threaded rod is formed in the upper supporting plate; a counter bore is formed in the bottom plate; the center line of the counter bore is collinear with the shaft axis of the threaded through hole; a lining sleeve is arranged in the counter bore, a through hole is formed in the vertical plate, a shaft sleeve is arranged in the through hole, a rotary shaft is arranged in the shaft sleeve, and the shaft sleeve and the rotary shaft are in clearance fit; the cam is fixedly connected to the rotary shaft; a ring-shaped groove is formed in the outline surface of the cam, an ejector pin is arranged between the cam and the bottom plate, and a roller wheel is arranged at the bottom end of the ejector pin; the top end of the ejector pin is positioned in the inner hole of the lining sleeve; the threaded rod is a hollow rod; the hole diameter of the inner hole of the threaded rod is greater than the diameter of a pin roll of the chain. The chain dismounting device can be used for overcoming the defects of low efficiency and a low safety coefficient of the chain dismounting in the prior art.

Description

technical field [0001] The invention relates to the field of chain removal tooling, in particular to a chain removal device. Background technique [0002] Chain transmission is an important form of mechanical transmission. The transmission chain generally adopts a sleeve roller chain, which is composed of an inner chain plate, an outer chain plate, a sleeve and rollers. The pin shaft and the outer chain plate, the sleeve and the inner chain plate are all interference partners. Each chain link is connected by an outer chain plate. When the chain link flexes and extends, the sleeve can rotate freely on the pin shaft. When the chain needs to be cut off, the pin shaft needs to be pressed out of the outer chain plates on both sides of the chain. When the equipment is running for a long time, it is inevitable that the chain will be worn out. However, after the chain is worn out, the chain will be elongated and loose, which will affect the accuracy of the chain transmission and ...
