Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile detection equipment, in particular to an aluminum profile flatness detection device. Background Art

[0002] After aluminum profiles are manufactured, they need to be tested for flatness and straightness. A common method involves placing the profile on a testing platform, inserting a caliper into the gap between the profile and the testing platform, and measuring the profile's flatness. The tester then uses their experience to observe the profile's straightness. This results in significant errors in straightness testing, making this method a significant disadvantage for profiles with strict shape tolerance requirements.

[0003] Chinese invention patent publication number CN112304259A discloses an aluminum profile flatness detection device. When the aluminum profile passes through a first measuring cabinet and a second measuring cabinet, a measuring roller will move on the aluminum profile in turn. When there is a protrusion on the surface of the aluminum profile, it will move upward against the measuring roller. Thus, a first distance infrared sensor and a second distance infrared sensor will detect the distance the measuring roller moves up and down, thereby measuring the flatness of the aluminum profile. This is conducive to more practical use of the aluminum profile flatness detection device. However, the above-mentioned detection probes are fixed and cannot be adjusted in angle. Some aluminum profiles require bevel processing, so that the fixed detection probes cannot detect the bevel of the aluminum profile, and thus cannot meet the detection requirements of different models of aluminum profiles.
