Problems solved by technology
The most notable disadvantages of the traditional method for repairing the surface of revolution are: 1. There is no good way to measure the actual radius of revolution of the surface of revolution at any position
[0003] 2. Since the actual radius of gyration of the gyratory surface at any position is not known, there has been a repair phenomenon during compensatory repairs.
Waste of repair materials and increased labor intensity
[0004] 3. Due to the over-repair in the repair process, after the repair is completed, it is necessary to increase the subsequent processing procedures such as turning, which makes the repair process complicated and increases the repair cost

The invention discloses an irregular rotating body detecting instrument and a repair welding method employing the same, belongs to the technical field of detection of curved surfaces, and provides an irregular rotating body detecting instrument capable of accurately measuring the actual rotating radius of a rotating surface and a repair welding method for an irregular rotating body. The irregular rotating body detecting instrument comprises a bracket, and is structurally characterized in that a guide sleeve is arranged at the upper end of the bracket; a guide rod of which the end part is provided with a roller is arranged in the guide sleeve; a return spring is arranged between the guide rod and the guide sleeve; and the guide rod is connected with a data acquisition element. The repair welding method comprises the following steps of: contacting the roller of the irregular rotating body detecting instrument with the rotating surface of the rotating body, and applying precompression; controlling the rotating body to rotate for one circle, acquiring a movement track of the guide rod by using the data acquisition element, and transmitting to a data processing device; processing an acquired signal by using the data processing device, and calculating repair welding quantity; and transmitting to a control system, and controlling a welding machine by using the control system to perform repair welding on the rotating body.
Description
technical field [0001] The invention belongs to the technical field of curved surface detection, and more specifically relates to an irregular rotating body detector and a repair welding method using the detector. Background technique [0002] In many occasions where rotary motion is performed, the rotary surface is the real working surface, such as the working surface of the friction wheel. The working surface of the slewing motion is often worn. When the wear reaches a certain level, the slewing surface becomes an approximately elliptical curved surface, which increases the deviation of the slewing radius, and there will be strong jumps during the movement; at this time, it is necessary to correct the slewing Make compensatory repairs on the surface to make the radius of gyration reach the specified value and make the gyration motion stable. The most notable shortcoming in the traditional method for repairing the surface of revolution is: 1, there is no good way to measur...
