Welding quality detection device of ceramic tile drilling bit

Abstract

The invention discloses a welding quality detection device of a ceramic tile drilling bit. The welding quality detection device comprises a worktable, an automatic feeding mechanism, a material conveying mechanism, a coupling agent coating mechanism and an ultrasonic detection mechanism, wherein a feeding hole is formed in the worktable; the material conveying mechanism comprises an annular material conveying belt, a driving motor and driving wheels for driving the material conveying belt to transmit; a plurality of clamping grooves are formed in an outer side wall of the material conveying belt; the bottom of the material conveying belt is fitted to the top of the worktable; when the clamping grooves in the outer side wall of the material conveying belt are aligned to the feeding hole in the worktable, the automatic feeding mechanism is used for jacking drilling bits to be detected into the clamping grooves; the ultrasonic detection mechanism is arranged at one side of the worktable and stretching-out end welding parts of the drilling bits to be detected in the clamping grooves on the material conveying belt are located in a detection opening of the ultrasonic detection mechanism. By adopting the welding quality detection device of the ceramic tile drilling bit, missed detection and erroneous detection, caused by anthropic factors, can be effectively avoided; the detection efficiency and accuracy of a product are improved and the labor intensity of detectors is reduced.

Description

technical field [0001] The invention relates to the technical field of drill bit quality detection, in particular to a ceramic tile drill bit welding quality detection device. Background technique [0002] In order to improve the drilling hardness and drilling efficiency of the drill bit, the existing drill bit generally has a cemented carbide blade embedded in the head of the drill rod, and the cemented carbide blade is used as the cutter head for drilling. It is a separate structure with the drill pipe head. During processing, the two need to be fixedly connected together by welding. Cemented carbide inserts have the characteristics of high hardness and good wear resistance, but they also have disadvantages such as high brittleness and poor toughness. When the cemented carbide blade is welded to the drill pipe head of medium carbon steel or low alloy steel, the welding performance directly affects the use effect of the cemented carbide blade; since the cemented carbide bl...

Problems solved by technology

Both of the above two methods of drill welding quality inspection require manual on-duty, and the detection efficiency is low, and it is easy to have missed inspections and wrong inspections. The manual labor intensity is high and cannot meet the needs of large-scale drill inspection.
