Description

Technical Field

[0001] The utility model relates to the technical field of double cams, and more specifically to an enhanced transmission structure of double cams. Background Art

[0002] The machine tool turntable is an accessory used to clamp the workpiece and rotate and index the workpiece. Its function not only enriches the processing capacity of the machine tool, but also significantly improves the processing efficiency and precision. The double cam is one of the important components of the machine tool turntable. In the traditional structure, in order to meet the high speed requirements of opening and closing, the most direct design is to increase the corresponding spring force. However, the increase in spring force causes a large impact force between the parts of the mechanism during movement, resulting in a relatively short overall life of the mechanism. In addition, the high spring force requires a lot of effort when manually operated, which makes it difficult to operate.

[0003] After searching, a Chinese patent with announcement number CN219534323U discloses a double cam drive structure. The utility model installs a double cam on the energy storage shaft. During the closing process, the first protrusion and the second protrusion of the double cam respectively contact the first pin and the second pin to push the closing to realize the transmission transmittability. In the process of transmitting the spring force, the force arm can be indirectly increased, the output of the energy storage spring work is reduced, and the comfort of operation is increased; at the same time, the impact between the parts of the mechanism is reduced, and the service life is improved, so that under the same conditions, the transmission efficiency can be greatly increased compared with the traditional cam. This embodiment reduces the spring force without affecting the opening and closing speed.

[0004] When the above-mentioned dual cam structure is in use, the dual cam is fixed on the energy storage shaft of the energy storage device, and the dual cam rotates with the energy storage shaft. However, when the dual cam or the energy storage device is damaged, it is necessary to replace the dual cam and the energy storage device with new ones as a whole. It is inconvenient to disassemble the dual cam and the energy storage device, and the maintenance cost is high. Utility Model Content
