[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Specific implementation cases:

[0020] like Figure 1As shown, a servo press for facilitating the replacement of a ram comprises a transmission portion 1, which is mounted on a servo press (not shown) and is used to control the movement of a ram mechanism. A mounting portion 2 is mounted below the transmission portion 1 for quickly replacing and removing different types of rams. A ram assembly 3 is mounted below the mounting portion 2. The transmission portion 1 is driven by a motor.

[0021] When replacing the ram of the servo press, the transmission part 1 controls the internal structure of the mounting part 2 through the motor drive, so that when the central axis (not marked in the figure) in the transmission part 1 moves upward, the mounting part 2 clamps the ram assembly 3, and when the central axis in the transmission part 1 moves downward, the mounting part 2 releases the ram assembly 3. The operator only needs to pull the ram assembly 3 out by hand. When installing, the mounting end of the ram assembly 3 is placed in the mounting hole (not marked in the figure) at the center of the mounting part 2, and then start the transmission part to clamp the ram assembly 3.

[0022] like Figure 2 As shown, the mounting portion 2 includes a shell 21, a connecting block 211 is installed on the shell 21, a limiting plate 22 is installed below the connecting block 211, a pressing block 23 is installed below the connecting block 211, a certain distance is set between the pressing block 23 and the limiting plate 22, a main shaft 24 is slidably installed at the center of the connecting block 211, the main shaft 24 is fixedly connected to the central axis in the transmission part 1, a pressing head 25 is provided at the top of the main shaft 24, a trapezoidal protrusion is provided on the outside of the top of the pressing head 25 (not marked in the figure), an inclined surface is provided at the upper edge of the pressing head 25 (not marked in the figure), and an arcuate surface (not marked in the figure) is provided on the top of the inner side of the pressing block 23;

[0023] The main shaft 24 moves up and down along the inner surface of the pressing block 23 driven by the central shaft;

[0024] The pressing head assembly 3 includes a riveting pressing head 33, a protective shell 31 is installed on the outside of the riveting pressing head 33, and a resistance block 32 is installed on the inner side of the upper end of the protective shell 31. The resistance block 32 is trapezoidal in shape and is installed in the space between the pressing block 23 and the limiting plate 22. The resistance block 32 is in contact with the trapezoidal protrusion provided on the outer side of the top of the pressing head 25. The outer surface of the pressing head 25 is slidably connected to the inner surface of the protective shell 31, and the outer surface of the protective shell 31 is slidably connected to the inner surface of the limiting plate 22.

[0025] When the pressure head assembly 3 is quickly installed and disassembled, the mounting end of the pressure head assembly 3 is first placed into the mounting hole at the center of the mounting portion 2, so that the interference block 32 installed on the protective shell 31 enters the space between the pressing block 23 and the limit plate 22, and the interference block 32 is clamped by the trapezoidal protrusion installed on the pressing block 23 to prevent it from falling. Then, the transmission part 1 is started to make the main shaft 24 move upward, and the inclined surface provided on the upper edge of the pressing head 25 moves along the arc surface provided on the inner top of the pressing block 23, bending the top of the pressing block 23 at a certain angle, so that the trapezoidal protrusion at the top of the pressing block 23 presses the protective shell 31, and the outer surface of the protective shell 31 is tightly attached to the limit plate 22, and the interference block 32 is clamped by the trapezoidal protrusion and cannot leave the pressing block 23 and the limit plate 2 2, thereby firmly fixing the pressure head assembly 3. When the pressure head assembly 3 needs to be replaced and disassembled, the driving part 1 moves the central axis downward, thereby causing the main shaft 24 to move downward. Its downward movement range is limited by the connecting block 211. When the main shaft 24 moves downward, the connection between the pressing head 25 and the pressing block 23 is restored to its original state, and the pressing block 23 is restored to its original state, so that the pressure head assembly 3 is relaxed. The operator can pull the pressure head assembly 3 downward. In the process of pulling the pressure head assembly 3 downward, the inclined surface of the trapezoidal interference block 32 moves along the trapezoidal protrusion provided on the outer side of the top of the pressing head 25, squeezing the pressing block 23 inward and tilting it, so that the interference block 32 leaves the space between the pressing block 23 and the limiting plate 22, and the disassembly is completed.

[0026] The riveting head 33 needs to be positioned when it is installed, so a positioning shaft 34 is provided at the center of the riveting head 33, and a positioning hole (not shown in the figure) is provided at the center of the pressing head 25. The positioning shaft 34 is slidably connected to the positioning hole;

[0027] When installing the pressure head assembly 3, the positioning shaft 34 at the center of the pressure head assembly 3 is installed into the positioning hole set at the center of the pressing head 25 to determine the installation position of the pressure head assembly 3, which facilitates the positioning of the space between the interference block 32 and the pressing block 23 and the limit plate 22, making the structure more stable after installation;

[0028] To sum up, the transmission part 1 is driven by the motor, so that the central axis inside it drives the main shaft 24 to move up and down. During installation, the main shaft 24 moves upward, and the clamping head 25 squeezes the clamping block 23 so that it firmly presses the protective shell 31 on the clamping head assembly 3 to the limit plate 22. During disassembly, the main shaft 24 moves downward, and the connection between the clamping head 25 and the clamping block 23 is restored to its original state. The clamping block 23 is restored to its original state, so that the clamping head assembly 3 is relaxed, and the operator pulls the clamping head assembly 3 downward. This process does not require bolt tightening, which can save a lot of time to complete the rapid disassembly and installation of the clamping head assembly 3.

[0029] The above description is merely a preferred embodiment of the present application. The scope of protection of the present application is not limited to the above embodiment. All technical solutions based on this concept fall within the scope of protection of the present application. It should be noted that for those skilled in the art, improvements and modifications that do not depart from the principles of the present application should also be considered within the scope of protection of the present application.
