The four corners of the bolt head of the traditional T-slot connection bolt are all rounded corners, which will make the contact area between the bolt and the T-slot too small and reduce the connection fastness, especially when used for connection. When aluminum or copper profiles are used, due to the low hardness of the material, it is more likely to cause deformation of the T-shaped groove and affect the connection effect. Furthermore, since the traditional T-bolt has no direction indicator, it is difficult for the installer to identify the installation state during installation.
In order to effectively improve the working efficiency of bearing installation when the equipment or device is being installed with flat pads, it is necessary to arrange the positions of the front and back of the flat pad.エ Time-consuming, labor-intensive, low production efficiency, high processing cost defects, at the same time, there is a shortage of unstable product quality, so the development of a flat pad front identification feeding mechanism has become a hot spot of industry research.
