Method for detecting thickness of thermal spraying coating and detection equipment applying method

Abstract

The invention discloses a method for detecting the thickness of a thermal spraying coating and detection equipment applying the method. The detection method comprises the following steps: A, a to-be-detected product is fixed on a clamp; b, the clamp drives the to-be-detected product to move in the X direction, the distance values b1 of multiple points on a straight line are detected through an upper laser sensor in the upper portion, and meanwhile the distance values b2 of the multiple points are detected through a lower laser sensor in the lower portion; c, the clamp drives the to-be-detectedproduct to move by a certain distance in the Y direction, then the clamp drives the to-be-detected product to move reversely in the X direction, an upper laser sensor is used for detecting distance values c1 of multiple points on the straight line, and meanwhile a lower laser sensor is used for detecting distance values c2 of the multiple points; and D, the distance value b1, the distance value b2, the distance value c1 and the distance value c2 are calculated through an algorithm to obtain the total thickness H of the bottom of the to-be-detected product, and the total thickness H is compared with a design value to judge whether the to-be-detected product is qualified or not.

Description

Technical field [0001] The invention relates to the technical field of thickness detection, in particular to a method for detecting the thickness of a thermal spray coating and a detection device using the same. Background technique [0002] Thermal spraying on cooking utensils such as pots and soup pots is a commonly used design. Some aluminum pots are sprayed with iron coating on the bottom of the pot, and the thickness of the iron coating is small, and the thickness accuracy is required to be 0.01mm. At present, most people use manual measurement. Workers use dial indicator to measure, which is slow in efficiency and poor in accuracy, making it difficult to meet the requirements. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, a method for detecting the thickness of a thermal spray coating is provided, which can quickly and accurately detect the thickness of the coating. [0004...
