Therefore, these and other directional terms should not be construed as limiting terms.
Referring to fig. 1-3, a section bar detection device includes a working platform 100, a detection mechanism and a section bar clamping mechanism, the detection mechanism is disposed on the working platform 100, the detection mechanism is disposed in the center of the working platform 100, and the section bar clamping mechanism includes two clamping assemblies respectively disposed on two sides of the detection mechanism. The two clamping assemblies are used for clamping the transverse section bar, and then the shearing strength of the section bar is detected by using the detection device.
Detection mechanism detects mounting bracket 11, vertical setting and detects cylinder 12, the vertical detection post 13 that sets up on detecting mounting bracket 11, the top of detecting post 13 be equipped with pressure sensor 14 and with the piston rod 121 bottom fixed connection that detects cylinder 12, the bottom of detecting post 13 is equipped with elastic contact head 15 and is used for pressing at the section bar top surface.
After the two clamping assemblies clamp the profile, the detection cylinder 12 is started, so that the piston rod 121 of the detection cylinder drives the detection column 13 to move downwards to a specified position, the elastic contact head 15 presses the top surface of the profile and is subjected to a reaction force, the reaction force is read by the reading pressure sensor 14, and if the value read by the reading pressure sensor 14 is lower than a standard threshold value, the profile is bent and deformed under the pressure of the detection column 13, namely the shearing strength of the product does not reach the standard. Because the section bar is the aluminium material article, consequently set up elastic contact 15 in the bottom that detects post 13, can play the effect of buffering to can avoid the indentation to appear in the section bar top surface.
The elastic contact head 15 is preferably made of rubber materials, such as rubber, natural rubber, silica gel and the like, the upper part of the elastic contact head 15 is in a cover shape and is sleeved at the bottom end of the detection column 13, in order to avoid the elastic contact head 15 from falling off, the elastic contact head 15 and the detection column are in interference fit, and the lower part of the elastic contact head 15 is used for being pressed on the top surface of the section bar.
Considering cost problem and later maintenance of being convenient for, the detection jar 12 of this application is preferred to be set up to the cylinder, and the cylinder has the service condition restriction few, and simple structure is not fragile simultaneously the relative pneumatic cylinder of price, the cheaper characteristics of electric jar.
However, the precision of the air cylinder is not as good as that of a hydraulic cylinder or an electric cylinder, and in order to avoid interference with the final detection result due to precision reasons, the detection mechanism needs to be provided with a limit component for limiting the maximum downward stroke of the detection column 13. The limiting assembly comprises a first limiting block 111 which is arranged on the detection mounting frame 11 and vertically penetrates through the detection column 13, and a stopping piece 131 which is arranged on the detection column 13 and is positioned above the first limiting block 111, wherein the stopping piece 131 can be abutted with the first limiting block 111 to limit the maximum lower stroke of the detection column 13.
Because the driving force of the detection cylinder 12 is relatively large, the collision force between the stopping piece 131 and the first limiting block 111 is also relatively large, and the first limiting block 111 is easily damaged after long use, a gasket 112 is fixed at the top of the first limiting block 111, and the gasket 112 is slidably sleeved outside the detection column 13 and is used for replacing the first limiting block 111 and the stopping piece 131 to abut.
