Description

Technical Field

[0001] The invention belongs to the technical field of flaw detection equipment, and in particular relates to a magnetic flux leakage flaw detection carbon brush slideway repair and grinding device. Background Art

[0002] The Yinliang Material Magnetic Flux Leakage Flaw Detection Equipment uses a belt motor to drag the magnetic flux leakage rotating host to work. The working voltage of the magnetic flux leakage yoke is transmitted to the carbon brush disc through the carbon brush. Since normal production requires long-term high-speed rotation, the carbon brush and the carbon brush disc slide will become very serious. If the carbon powder stuck in the carbon brush slide is not cleaned in time, it is very easy to cause a phase short circuit, thereby damaging the magnetic yoke and the magnetic flux leakage power module, causing equipment accidents and affecting the production rhythm.

[0003] Since the contact and friction positions of the carbon brushes in the slideway are inconsistent during equipment operation, the surface of the carbon brush disc slideway will be uneven, and the carbon brushes are prone to breakage or damage. Therefore, when the equipment is shut down for maintenance, it often takes a lot of manpower to grind and repair the slideway of the carbon brush disc to ensure that the slideway of the flaw detection disc is smooth and burr-free, and the inside of the slideway is clean and free of foreign matter.

[0004] Manual maintenance and repair methods cannot repair the slideway reasonably and effectively. It will not only greatly increase the daily workload of the staff, thereby reducing the working efficiency of the flaw detection equipment, but also because the skill level of each person in manual grinding is inconsistent, it is easy to cause uneven grinding of the slideway, which will cause secondary wear of the slideway.
