An automatic detection device for the inner flatness of ultra-thin metal pipe fittings

Abstract

The invention discloses an automatic detection device for the inner flatness of an ultra-thin metal pipe fitting, relates to the technical field of flatness detection, and comprises a support assembly for support, on which a positioning and clamping assembly, a detection assembly, and a numerical display assembly are installed. The assembly includes a base frame for support, an information receiver for receiving information is fixed on the base frame, a feed unit for driving the positioning and clamping assembly to move and an auxiliary unit for assisting the positioning of the metal pipe are installed on the base frame, The positioning and clamping assembly includes a clamping unit and a positioning unit for clamping metal pipes. The detection assembly includes a power unit and a detection unit for measuring the internal flatness of the metal pipe. The detection unit includes a planetary gear mechanism and is used for the internal flatness of the metal pipe. The measurement mechanism for degree detection, the numerical display component includes an elastic mechanism and a numerical display mechanism.

Description

Technical field [0001] The present invention relates to a flatness detection technology, and particularly relates to an ultra-thin metal inner tube Flatness detection means. Background technique [0002] For ultra-thin steel has been detected inside the flatness test is an important indicator of thin steel, but due to its characteristics of thin tubular member causes it to deform easily during detection of the resulting measurement accuracy. [0003] Patent Application No. 201520739006.0 proposes an apparatus for detecting the flatness automotive tube, comprising table, support means, clamping means, the flatness detecting means includes a holder flatness detecting means mounted on the work table, mounted on the fixed mounting plate, the mounting plate of the detecting means to accomplish this patent flatness detecting auto pipe fittings by clamping means and flatness detecting means for leveling but not ultra-thin steel detecting the degree of the patent when the tube is likely ...

Problems solved by technology

[0002] The internal flatness detection of ultra-thin steel pipes has always been an important indicator for inspecting ultra-thin steel pipes, but due to the characteristics of ultra-thin pipes, they are easily deformed during detection, resulting in low measurement accuracy

[0003] The patent application number 201520739006.0 proposes a device for detecting the flatness of automobile pipe fittings, including a workbench, a support device, a clamping device, and a flatness detection device. The flatness detection device includes a fixing seat installed on the workbench, The mounting plate installed on the fixed seat and the detection device installed on the mounting plate, this patent completes the flatness detection of automobile pipe fittings through the clamping device and the flatness detection device, but it does not perform flatness for ultra-thin steel pipes The detection of the flatness, the patent is easy to cause damage to the pipe fittings when clamping the pipe fittings, the patent can only measure whether the flatness is qualified when measuring the flatness, and cannot measure the specific flatness value, and the scope of application is small
