Introduction of space frame jackscrew

The jackscrews of the space frame structure are used for fixing, and it is usually drilled and tapped on the side wall of the sleeve. Then you can insert the shaft into the inner hole, and tighten the screw hole to achieve the tightening effect. Most of them are shaft holes, and jackscrews are used to hold the shaft to prevent it from moving back and forth. Most of the fasteners used between the shaft and the sleeve to prevent the shaft and sleeve from changing the position of the shaft during use. The jackscrew hole, as the name implies, is a screw hole for jacking up. It is convenient to disassemble when parts need to be disassembled during equipment overhaul or other situations. Screw the jackscrews into the hole to separate the two assembled parts in order to achieve the purpose of disassembly. Product designers should fully consider the disassembly and assembly of parts.

Jackscrews can be used to prevent relative movement between the shaft and the sleeve. There are also occasions where the top wire is used for easy disassembly. For example, if the two parts are closely matched, they can be separated by the jackscrews. It is preferably suitable for occasions requiring simple equipment and parts, with a certain degree of alignment, easy to install, and a sealing device with a double structure.

Jackscrews are often used in mining, metallurgy, textile, conveying machinery, etc. It is preferably suitable for occasions requiring simple equipment and parts, with a certain degree of alignment, easy to install, and a sealing device with a double structure. They can work in bad environments. They also have diversified structure, good versatility and interchangeability.

Now the "Jackscrew adjusting and tightening chain method" has been developed to improve work efficiency and safety factor. "Jacksrew adjusting and tightening method" solves the problem that the chain is broken due to the uneven force of the chain and the impact force is too strong when starting the operation. The complexity of tightening and cutting the chain is reduced, and accidents of jumping, breaking and breaking the chain caused by the loose chain are prevented, and the time for cutting the chain is also shortened.

There are threads inside the jackscrew, and jackscrew must be tightened after space frame is in place. There is a small groove on the high-strength bolt, and the jackscrew is tightened to press in the small groove to fix the bolt.
