Service HotlineThe head of the traditional screw is located outside the threaded hole and occupies a large space, which is not suitable for occasions with small space, nor is it suitable for occasions where the outer surface of the component is a working surface. For example, in the field of electronic products, or when connecting the shaft and the shaft sleeve, the Birminghammachine screw with a fully threaded structure on the outer surface is widely used.
Locating pins are widely used in mechanical equipment and automated assembly lines. There are many types of locating pins, including fixed locating pins, replaceable locating pins, tapered locating pins, edged locating pins, standard diamond locating pins, spring locating pins, etc. The function is to limit the free movement of parts and objects. Users often choose different positioning pins according to the actual conditions of the parts, for example, according to the occasion of use, requirements and performance, etc., to reasonably choose positioning pins of different shapes and performances. At present, users usually use a combination of cylindrical pins and edge-cutting positioning pins as the positioning method for gripper positioning methods in automatic line accompanying tooling and automatic grasping.
Among them, the pneumatic riveting machine is more commonly used. The pneumatic riveting machine is also equipped with a clamp for assembling the rivet. The existing clamp usually uses two rotating clamps for fastening and assembly, but the rotation easily causes the two clamps to buckle. Misalignment, thus affecting the assembly of the rivet.
