Description

Linear actuating device of sealed push chain

Technical Field

Background

In the prior art, the push chain is used as an important component of the linear actuating device and can be applied to various automatic production lines and various precise devices. With the continuous improvement of the requirements of the modern industry on the running speed, the precision and the continuous operation capability of the device, the lubrication problem of the pushing chain has become one of the key factors for restricting the performance and the reliability of the device.

Conventional lubrication methods generally rely on manually applying lubricating oil to the push chain at regular intervals using brushes to ensure smoothness of operation, but such lubrication methods are particularly unsuitable in high-speed operation environments. Firstly, when the pushing chain moves at a high speed, lubricating oil is very easy to be thrown off or evaporated, so that the lubricating effect is reduced, and frequent lubricating operation is needed, so that the labor cost is greatly increased, the continuous operation flow of the production line is interrupted, and the downtime of the device is increased. Secondly, the requirement of the pushing chain on lubrication is obviously increased in a high-speed state, if timely and effective lubrication and replenishment cannot be realized, friction between the pushing chain and a chain wheel and between the pushing chain and a guide rail can be rapidly increased, a large amount of heat energy is generated, serious faults such as overheating, deformation, breakage and the like of the pushing chain can be possibly caused, local abrasion of the pushing chain is aggravated, the whole service life is shortened, and serious threat is formed to the stability and the safety of the whole production line.

In modern industrial environments where efficient, clean, automated production is sought, it is clear that such traditional maintenance approaches have been difficult to meet production requirements, and how to better lubricate them has become a bottleneck restricting device performance improvement and production cost optimization.

In order to avoid the push chain from falling out in the high-speed operation process, a part of the push chain is stored in the driving box when the push chain runs to the maximum travel of the push chain. While this design prevents the push chain from backing out to some extent, under extreme operating conditions or in the event of accidents, there is still the possibility of dangerous situations in which the push chain as a whole protrudes from the device, posing a potential threat to the operator and to the device itself.

When high-speed operation, traditional split type box structure adopts a plurality of box bolt butt joints, the form of inside installs the guide rail additional is directed to the push chain, this kind of mode probably can lead to push chain and box frequent collision because of the box butt joint position is inaccurate, produce vibration and noise, influence operational environment quality and operating personnel comfort level, the key part of support push chain steady operation is regarded as to inside guide rail simultaneously, if the design intensity is insufficient to bear the load of long-time high-speed motion, will accelerate wearing and tearing, shorten life, and then influence entire system's operating efficiency and reliability.
