Service HotlineAt present, the locking washer is widely used in the upper wheel side locking of passenger cars. During assembly, the locking washer is bent perpendicular to the thread of the axle pipe, so as to prevent the protrusion from passing through the gap between the two tooth profiles of the thread and ensure the locking The stop gasket is always in the groove of the shaft tube and cannot be rotated to achieve the purpose of locking. This method is relatively simple and is currently used more;
Therefore, there is a need to design a bearing retaining ring disassembly and installation device that facilitates the installation and disassembly of the bearing retaining ring, and is safe and reliable.
Screws and bolts are common connecting fasteners. The diameter of the thread is as small as less than one millimeter and as large as several hundred millimeters or even larger. The vast majority of threaded connections are pre-tightened during assembly in order to enhance the rigidity, tightness, anti-loosening ability of the connection and prevent the sliding of the bolted connection under lateral load. The pre-tightening force is determined according to the force of the bolt group and the working requirements of the connection. For important threaded connections, the preload must be measured and controlled.
The national standard name of the cross recessed small pan head three combination screw is the cross recessed small pan head screw, the spring washer and the flat washer assembly. The national label is GB/T9074.8-1988. This 1988 refers to the year, that is, this standard is the standard issued by the country in 1988. The specifications of the cross recessed small pan head three combination screws, the company's minimum is M2.5, the shortest is 5mm, the largest is M10, and the longest is 90mm.
The automatic screw-removing device includes a manipulator and a screw-removing mechanism arranged on the manipulator, and the electric batch can drive the bit to rotate to remove the screws. Therefore, the above-mentioned automatic screw removal device can automatically remove the screws, which improves the removal efficiency and reduces the production cost. At the same time, the above-mentioned automatic screw removal device determines the coordinates of the screw through the visual recognition unit, which improves the degree of screw positioning, thereby improving the yield of the screw removal. The above-mentioned screw removal method can realize the automatic removal of the screw, and adsorb the screw through the bit head and drive the screw away from the workpiece.
