Wheel type permanent magnetic adsorption device

Abstract

The invention relates to the technical field of industrial robots, and discloses a wheel type permanent magnetic adsorption device. The device comprises an annular neodymium iron boron permanent magnet, an outer silicon steel magnetic conductive yoke, an inner silicon steel magnetic conductive yoke and a positioning sleeve, wherein one end of the positioning sleeve sleeves the outer circle of the center of the outer silicon steel magnetic conductive yoke, and the other end of the positioning sleeve sleeves the outer circle of the center position of the inner silicon steel magnetic conductive yoke; the annular neodymium iron boron permanent magnet is embedded in the groove between the outer silicon steel magnetic conductive yoke and the inner silicon steel magnetic conductive yoke; the outer silicon steel magnetic conductive yoke and a magnetic wheel driving shaft are fixed together through a bolt at the tail end of a driving shaft; and the outer silicon steel magnetic conductive yoke and the inner silicon steel magnetic conductive yoke are fixed and screwed respectively by threaded holes in side faces of the outer and inner silicon steel magnetic conductive yoke to form a sandwich structure. The wheel type permanent magnetic adsorption device adopts the sandwich structure, has relatively small size and light weight, and is convenient to assemble and disassemble, permanent magnets with different magnetisms can be replaced easily, and the magnetic wheel can be prevented from sliding in the rotating process, so that the coaxiality is ensured, the dislocation phenomenon cannot happen, and the assembly can be easily implemented.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a wheel-type permanent magnet adsorption device, which can be applied in the field of robots. The technical problem to be solved by the present invention is to provide a wheeled permanent magnet with small size, light weight, easy maintenance, high friction coefficient, and higher magnetic energy utilization rate than the existing permanent magnet adsorption device for walking equipment such as wall-climbing robots. Adsorption device to achieve reliable adsorption and flexible crawling of walking equipment such as wall-climbing robots on various magnetically permeable walls. Background technique [0002] In recent years, robots have been widely used and developed in various fields. It is an inevitable trend of social development to use robots to replace human beings in various labor-intensive, high-risk, simple and repetitive tasks. As a kind of mobile robot, the wall...

Problems solved by technology

[0005]Aiming at the above-mentioned technical deficiencies, the present invention provides a wheel-type permanent magnet adsorption device, which adopts a sandwich structure, and the annular permanent magnet is embedded in two pieces of high magnetic permeability In the groove between the high-efficiency yokes, such as silicon steel, iron-nickel alloy, etc., the two magnetic yokes fully contact and wrap the two poles of the permanent magnets that are magnetized in the axial direction, so that the magnetic lines of the two poles can be fully gathered, which not only improves the utilization rate of magnetic energy It also avoids the direct contact between the ring permanent magnet and the magnetic wall surface, and makes up for the defects of the ring permanent magnet being fragile and low in strength
