Abstract

The concentricity detection device comprises a profiling mechanism, a measuring mechanism and a device carrier, the profiling mechanism and the measuring mechanism are arranged on the device carrier, the profiling mechanism is connected with the measuring mechanism, the measuring mechanism is connected with the device carrier, and the profiling mechanism is used for being combined with a cooling fin oil pocket. The measuring mechanism is used for measuring the concentricity degree of the cooling fin oil pocket. Compared with the traditional method for judging the alignment condition of the spot-welded radiating fin oil pocket by manually observing the alignment condition with naked eyes, the device effectively avoids the problem of insufficient objectivity of manual observation, improves the judgment accuracy, can quantitatively reflect the tiny eccentricity of the radiating fin oil pocket even if the tiny eccentricity of the radiating fin oil pocket cannot be observed with naked eyes, and improves the measurement accuracy. A worker can conveniently and timely find out the eccentricity condition existing in welding of the cooling fins, the multi-point welding machine is timely adjusted, and the production efficiency and the product quality are effectively improved. And the concentricity of the cooling fins is quantified and is visually displayed, so that the adjusting efficiency of the multi-spot welding machine is improved.

Description

technical field [0001] The invention relates to the technical field of concentricity detection, in particular to a concentricity detection method and device. Background technique [0002] Oil heaters are common household heating equipment. The production process of oil heaters includes steps such as stamping, welding and spraying. Among them, the welding process is required for the processing and production of the heat sink of the oil heater. The welding of the heat sink is an important process, because the heat sink is an important part of the oil heater, and poor welding will directly affect the oil heater. The quality of the heater. [0003] At present, when using a multi-point welding machine for heat sink welding, in order to ensure the center alignment of the large and small heat sink oil bags, the welding machine adopts the pressing method of the upper and lower oil bag profiling devices to ensure the center alignment of the oil bags. However, when the product model...
