Precise part lifting, transferring and conveying device and lifting, transferring and conveying method

Abstract

The invention discloses a precise part lifting, transferring and conveying device and a lifting, transferring and conveying method. The device comprises carts, a trolley, a lifting device and a magnetic attraction device. The magnetic attraction device comprises a magnetic core, steel claws, a cooling pipeline, an inflation pipeline and a buffer component. The cooling pipeline extends to the magnetic core from a lifting arm, surrounds the outer side of the magnetic core and the space between the steel claws and is used for cooling the magnetic core. The inflation pipeline is connected with the buffer component and used for inflating high-pressure gas into the buffer component, so that the buffer component can generate air floatation buffer between the steel claws and a precise part. According to the precise part lifting, transferring and conveying device and the lifting, transferring and conveying method, mechanical deformation and temperature deformation of the precise part in the lifting and transferring process can be avoided, and it is guaranteed that the size of the precise part meets the standard.

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...

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.
