Technical Field

[0002] The ram is a key component of a servo press, responsible for transmitting the press force to the workpiece, enabling operations such as stamping, forming, and pressing. When processing workpieces with different shapes and processing requirements, specialized rams are required to meet specific processing needs. For example, specialized rams designed for complex workpieces can provide higher processing precision.

[0003] When replacing the pressure head, it needs to be adjusted and aligned, and the installation and disassembly time is long. Therefore, it is necessary to provide a new type of servo press pressure head mechanism to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of servo press head mechanism, including a transmission part for controlling the movement of the entire head mechanism, characterized in that: a fixed part is installed below the transmission part for main installation and disassembly work, and a clamp is installed below the fixed part; the fixed part includes a connecting frame, the connecting frame is fixedly connected to the transmission mechanism, a first limit frame is installed below the connecting frame, a limit rod is slidably installed in the first limit frame, a second limit frame is installed below the first limit frame, the second limit frame is fixedly connected to the rotating shaft, the limit rod is fixedly connected to the second limit frame, a clamping block is installed below the limit rod for clamping the head, and a protective shell is installed on the outside of the first limit frame to protect the stability of the internal structure.

[0017] 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.

[0018] Specific implementation cases:

[0019] like Figure 1 As shown, a new type of servo press head mechanism includes a transmission part 1 for controlling the movement of the entire head mechanism. A fixing part 2 is installed below the transmission part 1 for main installation and removal work. A chuck is installed below the fixing part 2. The transmission part 1 is driven by a motor;

[0020] The specific working principle is as follows: the pressing head 3 is installed in the bottom cavity of the fixing part 2, and the transmission part 1 is driven by the motor to provide transmission force to the fixing part 2 so as to clamp and install the pressing head 3 and loosen and disassemble it;

[0021] like Figure 2 As shown, a transmission mechanism 11 is provided below the transmission part 1 for controlling the operation of the entire mechanism, and a rotating shaft (not shown in the figure) is provided in the transmission mechanism 11;

[0022] The transmission mechanism 11 is a servo lifting and rotating mechanism which is a prior art and will not be described in detail here;

[0023] The fixing part 2 includes a connecting frame 21, which is fixedly connected to the transmission mechanism 11. A first limiting frame 23 is installed below the connecting frame 21, and a limiting rod 24 is slidably installed in the first limiting frame 23. A second limiting frame 25 is installed below the first limiting frame 23, and the second limiting frame 25 is fixedly connected to the rotating shaft. The limiting rod 24 is fixedly connected to the second limiting frame 25, and a clamping block 26 is installed below the limiting rod 24 for clamping the pressing head 3. The clamping block 26 contacts the lower bottom surface of the second limiting frame 25. The limiting rod 24 and the clamping block 26 are provided in several groups. A protective shell 22 is installed on the outside of the first limiting frame 23 to protect the stability of the internal structure;

[0024] The first limiting frame 23 is provided with a plurality of groups of straight limiting grooves 231, and the second limiting frame 25 is provided with a plurality of groups of arc limiting grooves 251;

[0025] The limiting rod 24 moves along the groove wall in the straight limiting groove 231, and the limiting rod 24 moves along the groove wall in the arc limiting groove 251;

[0026] For ease of understanding, the end of the straight limiting groove 231 close to the axis is considered as the inner end, the other end of the straight limiting groove 231 is considered as the outer end, the end of the arc limiting groove 251 close to the axis is considered as the proximal end, and the other end of the arc limiting groove 251 is considered as the distal end. In the initial state of the fixing part 2, the limiting rod 24 is located at the outer end of the straight limiting groove 231 and also at the distal end of the arc limiting groove 251, and the clamping block 26 is in an open state.

[0027] When the fixing part 2 is working, the operator now puts the pressure head 3 to be replaced into the cavity formed by the clamping block 26 below the fixing part 2, starts the transmission mechanism 11, causes the rotating rod to rotate, drives the second limiting frame 25 to rotate, and the connecting frame 21 and the first limiting frame 23 are fixed. Because the limiting rod 24 moves in the straight limiting groove 231 of the first limiting frame 23, it also moves in the arc limiting groove 251 in the second limiting frame 25. The rotation of the second limiting frame 25 causes the limiting rod 24 to move from the distal end to the proximal end of the arc limiting groove 251. At the same time, it is restricted by the straight limiting groove 231 in the first limiting frame 23, so that the limiting rod 24 only makes a linear motion from the outer end to the inner end of the straight limiting groove 231, and then the clamping block 26 installed below the limiting rod 24 moves close to the central axis until the pressure head 3 is clamped.

[0028] When the pressure head 3 needs to be disassembled, the operator only needs to start the transmission mechanism 11 to rotate the rotating shaft in the opposite direction, so that the fixing part 2 returns to the initial state and the pressure head 3 can be disassembled;

[0029] In order to make the clamping block 26 clamp more securely, the clamping block 26 is provided with anti-slip rubber to increase the friction between the side surfaces of the clamping block 26 and the pressure head 3 when clamping, so that the pressure head 3 is not easy to fall off during operation;

[0030] In order to make the internal structure of the fixing part 2 more stable, the first limiting frame 23 is slidably connected to the second limiting frame 25, and an arc-shaped slide rail (not shown in the figure) is provided below the first limiting frame 23, so that the second limiting frame 25 can rotate on the lower surface of the first limiting frame 23, and the protective shell 22 is slidably connected to the clamping block 26. The sliding connection is connected through the slide rail, so that the position below the clamping block 26 is not easily offset, which affects the clamping effect, and at the same time increases the stability of the overall internal structure of the fixing part 2;

[0031] To sum up, the second limit frame 25 is driven to rotate by the rotating shaft in the motor-driven transmission mechanism 11, so that the limit groove moves along the groove wall of the arc limit groove 251 in the second limit frame 25, and at the same time is restricted by the groove wall of the straight limit groove 231 in the first limit frame 23, driving the clamping block 26 to approach or move away from the central axis of the fixed part 2, so as to utilize the cavity formed in the clamping block 26 to install and disassemble the pressure head 3.

[0032] 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.
