Lifting, transferring, and conveying device and method for lifting, transferring, and conveying precision parts

Abstract

A precision parts lifting and transporting device and a lifting and transporting method, the device includes a cart, a trolley, a lifting device, and a magnetic attraction device. The magnetic attraction device includes a magnetic core, steel claws, cooling pipes, air-filling pipes, and buffer components; the cooling pipe extends from the lifting arm to the magnetic core, and surrounds the outside of the magnetic core and between the steel claws to cool the magnetic core; the air-filling pipe It is connected with the buffer part and is used to fill the buffer part with high-pressure gas, so that the buffer part can generate air floating buffer between the steel claw and the precision parts. The invention can realize the avoidance of mechanical deformation and temperature deformation of the precision parts during the process of lifting and transferring, and ensure that the size of the precision parts conforms to the specification.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a lifting and conveying device for precision parts. Background technique [0002] At present, conventional lifting and conveying devices generally use mechanical gripping, clamping or hoisting to lift and transfer. However, these methods have a large mechanical contact force. This mechanical contact force is not only used to lift the parts, but also has undesirable friction, torsion, strain, etc., which will cause the parts to wear and deform, which is very detrimental to the maintenance of the performance of precision parts, and even damages the parts. While parts typically have certain tolerances, precision parts cannot allow this to happen. [0003] Although also there is the technical scheme that uses electromagnet technology to carry out part lifting in the prior art. However, the huge suction force of the electromagnet will cause an unexpected collision between the part...

AI Technical Summary

Problems solved by technology

In particular, for some precision parts, it is necessary to maintain a constant temperature during assembly, especially when low temperature assembly is required, the change of temperature will cause a small change in its external dimensions, which will affect the precise assembly

The clamping part of the lifting device will cause the temperature of the contact parts to rise due to current, mechanical friction and other reasons, which will lead to greater assembly errors of precision parts, or even incorrect assembly.
