[0002] In the field of industrial production and automation, clamping and manipulating round workpieces is a basic and important task. In the early days, round workpieces were clamped using simple manual or mechanical clamps. However, these clamps often suffered from problems such as cumbersome operation, low precision, poor adaptability, and narrow application range when clamping round workpieces. With the continuous improvement of industrial automation, there is a need for a mechanism that can efficiently and accurately achieve the clamping function. The linkage mechanism has emerged to meet this need. It uses the combined motion of linkages to convert the motion of the power source into the opening and closing motion of the clamping mechanism. It has the advantages of simple structure, reliable motion, and high precision. Utility Model Content

There are two brackets, which are respectively fixed at the left and right ends of the base. The support plate is fixed above the two brackets, and the two brackets are used to connect the base and the support plate. The slide rail is horizontally installed on the support plate. There are two sliders, which are respectively installed at both ends of the slide rail. Each end of the connecting block has a cylindrical pin, for a total of four cylindrical pins. One end of the connecting rod... A sliding groove is provided, and the connecting rod is connected to the connecting block by being sleeved on the cylindrical pin through the sliding groove. The other end of the connecting rod passes through the support plate and is connected to the side of the slider. There are 4 connecting rods, namely connecting rod a, connecting rod b, connecting rod c, and connecting rod d. Connecting rod a and connecting rod b are a group connected to one of the sliders. Connecting rods a and b are symmetrically installed on both sides of the connecting block. Connecting rods c and d are a group connected to another slider. Connecting rods c and d are symmetrically installed on both sides of the connecting block. There are 2 clamping arms, which are fixedly installed on the 2 sliders respectively. The clamping arms are provided with V-shaped grooves. The worktable is fixed to the support plate by 4 support rods. The worktable is located directly above the middle position of the slide rail.

[0005] Furthermore, the bracket is an L-shaped bracket.

[0006] Furthermore, the support plate is provided with a hollowed-out sliding groove, through which the connecting rods a, c, b and d pass and are connected to the slider for assembly.

The piston cylinder 1 is installed in the center below the base 2. The piston rod 11 in the piston cylinder 1 passes through the base 2 and is fixedly connected to the connecting block 4. When the piston cylinder 1 is activated, the piston rod 11 extends, and the piston rod 11 drives the connecting block 4. The base 2 is reciprocating. There are two brackets 3, fixed to the left and right ends of the base 2 respectively. The support plate 5 is fixed above the two brackets 3. The two brackets 3 connect the base 2 and the support plate 5, providing sufficient space between the support plate 5 and the base 2 for installing other components. The slide rail 6 is horizontally mounted on the support plate 5. There are two sliders 7, mounted at both ends of the slide rail 6, allowing them to move back and forth. The connecting block 4 has four cylindrical pins 85 on each side. A cylindrical pin is used, and one end of the connecting rod 8 is provided with a sliding groove. The connecting rod 8 is sleeved on the cylindrical pin 85 through the sliding groove and connected to the connecting block 4. When the connecting block 4 reciprocates, it can drive the connecting rod 8 to reciprocate. There are four connecting rods 8: a-connecting rod 81, b-connecting rod 82, c-connecting rod 83, and d-connecting rod 84. Connecting rods a-connecting rod 81 and b-connecting rod 82 are a group connected to one of the sliders 7. Connecting rods a-connecting rod 81 and b-connecting rod 82 are symmetrically installed on both sides of the connecting block 4. Connecting rods c-connecting rod 83 and d-connecting rod 84 are a group connected to the other slider 7. The connecting rod 84 and the piston cylinder 1 are symmetrically installed on both sides of the connecting block 4. When the piston cylinder 1 is started, the piston rod 11 of the piston cylinder 1 reciprocates. One end of the connecting rod 8 with a sliding groove is sleeved on the cylindrical pin 85. The piston rod 11 reciprocates, thereby driving the connecting rod 8 to reciprocate. One end of the connecting rod 8 is connected to the slider 7, thereby driving the slider 7 to slide back and forth. The movement of the slider 7 drives the clamping arm 10 to move, thereby completing the clamping and fixing of the workpiece. The worktable 9 is fixed on the support plate 5 by four support rods 101. The worktable 9 has a supporting function for the workpiece.

[0018] Preferably, the bracket 3 is L-shaped, which has the function of balancing support.

[0019] Preferably, the base 2 has a hole in the center that allows the piston rod 11 of the piston cylinder 1 to move freely back and forth. The piston rod 11 moving back and forth in the hole can drive the connecting block 4 and thus drive the reciprocating motion of the entire mechanism.

[0020] Preferably, the connecting rod 8 is L-shaped.

[0021] Preferably, the support plate 5 is provided with hollowed-out sliding grooves at the front and rear. Links a 81 and c 83, b 82 and d 84 pass through the hollowed-out sliding grooves and pass through the support plate, ensuring that the clamping movement can be stable and smooth.

[0022] Preferably, the clamping arm 10 is composed of a Z-shaped clamping arm 1011 and a base 1012. The clamping arm 10 is connected and fixed to the slider 7 through the base 1012. The clamping arm 10 is an integral structure and is designed in a Z-shape to avoid collision with the worktable and prevent friction, thus ensuring the accuracy of clamping.

[0023] Preferably, the workbench 9 is a cube, with support rods 101 of the same specification fixedly connected to its four corners. The four support rods 101 are arranged on both sides of the slide rail, so that the operation of the mechanism is not delayed and the support function is provided.

[0024] In practical use, this invention features four connecting rods mounted simultaneously on a single connecting block. A piston cylinder drives the connecting block, which in turn moves all four connecting rods at the same time. The connecting rods are L-shaped and integrated into a single unit. This ensures even force distribution in all directions when the clamping arm is driven to perform the clamping motion. Simultaneously, the workpiece is automatically pushed to a fixed position. Furthermore, the clamping arm has a V-groove, enabling smooth and rapid clamping of round workpieces of different sizes. Operation is simple and convenient, with a wide range of applications. The connecting rods slide up and down within the grooves of the support plate, and a dedicated worktable is provided in the middle for workpiece clamping. Workpiece positioning is highly accurate. Additionally, the clamping arm is Z-shaped, preventing it from touching the worktable and causing vibrations that could lead to inaccurate workpiece clamping. This ensures accurate clamping, simple operation, and improved work efficiency during operation.
