[0002] Modern production lines require increasingly higher compatibility and equipment capacity, and the demand for high-frequency and high-stability loading of cylindrical parts of different diameters is also becoming increasingly urgent. The structure of the existing clamping mechanism is relatively complex. When clamping cylindrical workpieces axially, a clamping member with a groove is usually directly used, so that the clamping member with a groove matches the diameter of the cylindrical workpiece for clamping to ensure clamping stability. However, this method will make it impossible to clamp cylindrical workpieces of different diameters. Or, even if a tool change is used to adapt to the clamping of cylindrical workpieces of different diameters, the tool change process not only requires the replacement of many parts, the process is complicated, and it also has high requirements on the operating standards of technicians, resulting in high production costs. In addition, when clamping workpieces, the existing clamping mechanism also has the problem of inaccurate positioning and low clamping efficiency, which greatly affects production efficiency.

[0027] The utility model proposes a clamping device and a production line. The production line includes a conveying table 6 and a clamping device. The clamping device is used to clamp a cylindrical workpiece 10 on the conveying table 6. The cylindrical workpiece 10 is placed along the length direction of the conveying table 6 with its axis horizontal. The cylindrical workpiece 10 can be transported on the conveying table 6. The clamping device includes a clamping mechanism 1, which can clamp the cylindrical workpiece 10. This clamping mechanism 1 is provided with a positioning rod 113 on the clamping jaw, so that the positioning rod 113 contacts the circumferential surface of the cylindrical workpiece 10 when clamping the cylindrical workpiece 10, which solves the limitations of the prior art of using a clamping member with a groove to clamp the cylindrical workpiece 10, and can adapt to cylindrical workpieces 10 of different diameters, while ensuring clamping stability relative to ordinary clamping jaws; secondly, when clamping the workpiece, the first clamping jaw 111 and the second clamping jaw 112 move toward each other at the same time, the second clamping jaw 112 moves upward to receive the cylindrical workpiece 10 and then continues to lift it upward, and the first clamping jaw 111 moves downward to cooperate with the second clamping jaw 112 to complete the clamping, which can ensure that the cylindrical workpiece 10 is positioned relative to the preset clamping axis of the clamping mechanism 1, that is, when clamping cylindrical workpieces 10 of different diameters, their center position remains unchanged, thereby ensuring the loading accuracy of the clamping device.

[0028] Reference Figure 1 The clamping mechanism 1 includes a clamping jaw assembly 11 and a supporting assembly 13. The clamping jaw assembly 11 includes a first clamping jaw 111 and a second clamping jaw 112. The first clamping jaw 111 and the second clamping jaw 112 are both slidably arranged on the supporting assembly 13. The preset clamping axis of the clamping jaw assembly 11 is parallel to the axis of the cylindrical workpiece 10. When the cylindrical workpiece 10 is placed on the conveying table 6, the preset clamping axis of the clamping jaw assembly 11 is specifically located below the axis of the cylindrical workpiece 10. The first clamping jaw 111 is located above the second clamping jaw 112. The second clamping jaw 112 can move upward and then take over the cylindrical workpiece 10 to lift the cylindrical workpiece 10 upward. The first clamping jaw 111 can move downward to cooperate with the second clamping jaw 112 to clamp the cylindrical workpiece 10, and make the axis of the cylindrical workpiece 10 coincide with the preset clamping axis of the clamping jaw assembly 11. It can be understood that the preset clamping axis refers to the center line of the clamping area enclosed by the first clamping jaw 111 and the second clamping jaw 112 of the clamping jaw assembly 11, and the clamping jaw assembly 11 has only one preset clamping axis. When clamping cylindrical workpieces 10 of different diameters, the axis of the cylindrical workpiece 10 coincides with the preset clamping axis.

[0029] This arrangement can ensure that the cylindrical workpiece 10 is positioned relative to the preset clamping axis of the clamping mechanism 1, that is, to ensure that when changing to clamp cylindrical workpieces 10 of different diameters, its center position relative to the clamping jaw assembly 11 remains unchanged. For example, when the clamping jaw assembly 11 clamps a cylindrical workpiece 10 of a larger diameter, the first clamping jaw 111 and the second clamping jaw 112 move toward each other at the same time, and the second clamping jaw 112 moves upward a short distance after receiving the cylindrical workpiece 10, and then the cylindrical workpiece 10 can be lifted until the axis coincides with the preset clamping axis, and then the first clamping jaw 111 cooperates with the second clamping jaw 112 to achieve clamping; when a cylindrical workpiece 10 of a smaller diameter is to be clamped, the first clamping jaw 111 and the second clamping jaw 112 move toward each other at the same time, and the second clamping jaw 112 moves upward a longer distance after receiving the cylindrical workpiece 10, and then the cylindrical workpiece 10 can be lifted until the axis coincides with the preset clamping axis, and then the first clamping jaw 111 cooperates with the second clamping jaw 112 to achieve clamping. Therefore, whether clamping a cylindrical workpiece 10 with a larger diameter or a smaller diameter, its axis can coincide with the preset clamping axis of the clamping jaw assembly 11, ensuring that its center position remains unchanged when clamping cylindrical workpieces 10 with different diameters.

[0030] Preferably, the first clamping jaw 111 and the second clamping jaw 112 each include two positioning rods 113. The positioning rods 113 extend along the length direction of the conveyor table 6 and are arranged horizontally with the axis of the cylindrical workpiece 10. When the clamping jaw assembly 11 clamps the cylindrical workpiece 10, the positioning rods 113 contact the circumferential surface of the cylindrical workpiece 10. When clamping the cylindrical workpiece 10, the first clamping jaw 111 and the second clamping jaw 112 move toward each other at the same time. During the upward movement of the second clamping jaw 112, the positioning rods 113 contact the cylindrical workpiece 10. After the positioning rods 113 contact the cylindrical workpiece 10, the second clamping jaw 112 continues to move upward. The first clamping jaw 111 moves downward to cooperate with the second clamping jaw 112 to clamp the cylindrical workpiece 10. At this time, the cylindrical workpiece 10 is fixedly clamped by the four positioning rods 113. This arrangement not only ensures clamping stability, but also can clamp cylindrical workpieces 10 of different diameters.

[0031] Furthermore, when the clamping jaw assembly 11 clamps the cylindrical workpiece 10, the gap between the two positioning rods 113 of the second clamping jaw 112 can form an avoidance space, and then when the second clamping jaw 112 moves upward, the conveying table 6 can be placed in the avoidance space between the positioning rods 113, so that the second clamping jaw 112 can directly pass through the conveying table 6 and then receive the cylindrical workpiece 10, without setting up other redundant transfer mechanisms to transfer the cylindrical workpiece 10 to the clamping jaw assembly 11, simplifying the structure while reducing production costs.

[0032] Reference Figure 1The clamping mechanism 1 also includes a position feedback component 12, which is connected to the first clamping jaw 111 and / or the second clamping jaw 112. The clamping jaw component 11 has an initial position and a clamping position. The first clamping jaw 111 and the second clamping jaw 112 in the initial position are far away from each other, and the distance between the first clamping jaw 111 and the second clamping jaw 112 is the maximum opening and closing distance of the clamping jaw component 11. The first clamping jaw 111 and the second clamping jaw 112 in the clamping position can clamp the cylindrical workpiece 10. The position feedback component 12 can detect the displacement of the first clamping jaw 111 and / or the second clamping jaw 112. Therefore, by subtracting the displacement of the first clamping jaw 111 and the second clamping jaw 112 detected by the position feedback component 12 from the distance between the first clamping jaw 111 and the second clamping jaw 112 in the initial position, it can be determined whether the diameter size of the cylindrical workpiece 10 is within the diameter size range that meets the production requirements. It can be understood that since the first jaw 111 and the second jaw 112 move toward each other at the same time to clamp the cylindrical workpiece 10, the displacement of the first jaw 111 and the second jaw 112 is the same. Therefore, whether the position feedback component 12 is connected only to the first jaw 111 or the second jaw 112, or to the first jaw 111 and the second jaw 112 at the same time, it can be used to determine whether the diameter size of the cylindrical workpiece 10 meets the production requirements.

[0033] Furthermore, the clamping mechanism 1 also includes a first drive assembly, the output end of which is in transmission connection with the first clamping jaw 111 and the second clamping jaw 112. The first drive assembly includes two driving members that respectively drive the first clamping jaw 111 and the second clamping jaw 112. The two driving members can achieve synchronous drive, thereby ensuring that the first clamping jaw 111 and the second clamping jaw 112 move toward each other at the same time. In addition, the first drive assembly can use a piston cylinder, and a magnetic ring is installed on the piston of the cylinder. The corresponding position feedback assembly 12 can use a magnetic ring position sensing sensor. The magnetic ring position sensing sensor can sense the position of the magnetic ring, thereby detecting the piston cylinder stroke and then detecting the displacement of the first clamping jaw 111 and / or the second clamping jaw 112.

[0034] In order to further ensure the clamping stability of the clamping jaw assembly 11 , an anti-slip protrusion is further provided on the positioning rod 113 to increase the friction between the positioning rod 113 and the cylindrical workpiece 10 .

[0035] Reference Figure 1-Figure 2 The clamping device also includes a first driving mechanism 3, which is used to drive the clamping mechanism 1 to move axially along a preset clamping axis, thereby realizing the clamping of the cylindrical workpiece 10 by the clamping mechanism 1. Specifically, the output end of the first driving mechanism 3 is connected to the clamping mechanism 1, and can drive the clamping mechanism 1 to move linearly.

[0036] Furthermore, the clamping device also includes a detection sensor 2, which is arranged in front of the clamping mechanism 1, and is used to detect whether the cylindrical workpiece 10 is placed in the clamping position. When the detection sensor 2 detects that the cylindrical workpiece 10 located closest to the clamping mechanism 1 is placed in the clamping position, the first drive mechanism 3 drives the clamping mechanism 1 to move horizontally along the length direction of the conveying table 6 until the cylindrical workpiece 10 is placed between the first clamping jaw 111 and the second clamping jaw 112, and then the clamping jaw assembly 11 clamps the cylindrical workpiece 10.

[0037] Specifically, the detection sensor 2 includes a transmitter 21 and a receiver 22. The transmitter 21 is used to transmit signals, and the receiver 22 is used to receive signals emitted by the transmitter 21. The transmitter 21 and the receiver 22 are respectively arranged on both sides of the end of the conveyor table 6. The end of the conveyor table 6 is the end close to the clamping mechanism 1. When the cylindrical workpiece 10 is transported to the end on the conveyor table 6, it is just between the transmitter 21 and the receiver 22. At this time, the signal emitted by the transmitter 21 is blocked by the cylindrical workpiece 10 and cannot be received by the receiver, which means that the cylindrical workpiece 10 reaches the clamping position and the clamping mechanism 1 starts to move to prevent the subsequent clamping jaw assembly 11 from empty grabbing, thereby reducing the grabbing efficiency.

[0038] The clamping device also includes a second drive mechanism 4, which is used to drive the clamping mechanism 1 to flip in the vertical plane where the preset clamping axis is located, thereby realizing the clamping of the cylindrical workpiece 10 by the clamping mechanism 1 and the loading operation after clamping. Specifically, the second drive mechanism 4 is connected to the first drive mechanism 3, and the output end of the second drive mechanism 4 is connected to the clamping mechanism 1. The second drive mechanism 4 can drive the first drive mechanism 3 and the clamping mechanism 1 to flip in the vertical plane where the preset clamping axis is located. Specifically, when no clamping is performed, the clamping mechanism 1 is in a vertical direction. When the cylindrical workpiece 10 reaches the clamping position, the second drive mechanism 4 drives the first drive mechanism 3 and the clamping mechanism 1 to flip in the vertical plane where the preset clamping axis is located toward the side close to the conveying table 6. After the first drive mechanism 3 and the clamping mechanism 1 are flipped to a horizontal state, the first drive mechanism 3 drives the clamping mechanism 1 to move horizontally in the direction close to the conveying table 6 until the clamping jaw assembly 1 reaches the clamping position. Furthermore, the clamping mechanism 1 also includes a support member 14, which is provided on the support assembly 13 and is located between the first clamping jaw 111 and the second clamping jaw 112, and is used to abut against the end face of the cylindrical workpiece 10 to axially position the cylindrical workpiece 10. Specifically, when the clamping jaw assembly 11 reaches the clamping position, the first clamping jaw 111 and the second clamping jaw 112 clamp the cylindrical workpiece 10, and then the second drive mechanism 4 drives the first drive mechanism 3 and the clamping mechanism 1 to flip toward the side away from the conveying table 6 within the vertical plane where the preset clamping axis is located. During this process, the support member 14 can abut against the end face of the cylindrical workpiece 10, thereby supporting the cylindrical workpiece 10, making the clamping of the cylindrical workpiece 10 more stable.

[0039] In addition, the end of the support member 14 away from the cylindrical workpiece 10 is connected to the output end of the second drive assembly, so that the support member 14 can be moved and adjusted along the length of the positioning rod 113 to control the distance that the cylindrical workpiece 10 extends into the clamping mechanism 1. In other words, by adjusting the position of the support member 14, the fitting length between the clamping mechanism 1 and the cylindrical workpiece 10 can be adjusted. Preferably, the second drive assembly can be a telescopic cylinder, which can be specifically disposed within the support assembly 13.

[0040] Furthermore, the second driving mechanism 4 is fixedly mounted on the mounting plate 5 , and the mounting plate 5 provides support for the entire clamping device.

[0041] It is worth mentioning that the clamping mechanism 1 has a first position, a second position, a third position and a fourth position, wherein the first position is the position when the clamping mechanism 1 is in a vertical state and is not driven by the first drive mechanism 3, that is, the position where the clamping mechanism 1 is in the lower limit state; the second position is the position when the clamping mechanism 1 is in a vertical state, and the clamping mechanism 1 is driven to the upper limit state by the first drive mechanism 3; the third position is the position when the clamping mechanism 1 is in a horizontal state, and the clamping mechanism 1 is not driven by the first drive mechanism 3, that is, the position where the clamping mechanism 1 is in the right limit state; the fourth position is the position when the clamping mechanism 1 is in a horizontal state, and the clamping mechanism 1 is driven to the left limit state by the first drive mechanism 3. It can be understood that when the clamping mechanism 1 is in the fourth position, the clamping claw assembly 11 is in the clamping position, and up, down, left and right are based on Figure 1 and Figure 2 Description of the location.

[0042] The working process of the clamping device is:

[0043] The cylindrical workpiece 10 is first arranged horizontally on the conveyor table 6 for conveyance, with the clamping mechanism 1 in the first position and the clamping jaw assembly 11 in the initial position. When the detection sensor 2 detects that the cylindrical workpiece 10 is in the clamping position, the second drive mechanism 4 drives the first drive mechanism 3 and the clamping mechanism 1 to rotate to a horizontal state. At this time, the clamping mechanism 1 is in the third position. Then the first drive mechanism 3 drives the clamping mechanism 1 to the fourth position, and the clamping jaw assembly 11 reaches the clamping position. The second drive assembly adjusts the support 14 to a suitable position, and the first drive assembly drives the clamping jaw assembly 11 to the clamping position to clamp the cylindrical workpiece 10. At the same time, the position feedback assembly 12 determines whether the diameter size of the cylindrical workpiece 10 meets the requirements. If it meets the requirements, The first drive mechanism 3 drives the clamping mechanism 1 to return to the third position, successfully separating the cylindrical workpiece 10 from the conveying table 6, and avoiding the interference between the clamped cylindrical workpiece 10 and the adjacent cylindrical workpiece 10 on the conveying table 6. Then the second drive mechanism 4 drives the first drive mechanism 3 and the clamping mechanism 1 to rotate to a vertical state. At this time, the clamping mechanism 1 is in the first position. Then the first drive mechanism 3 drives the clamping mechanism 1 to the second position. At this time, the cylindrical workpiece 10 is positioned in the center of the vertical state and is taken away by other devices. The clamping device completes a loading process. When the clamping mechanism 1 is in the second position, the first drive assembly can drive the clamping jaw assembly 11 to move to the initial position, release the cylindrical workpiece 10 so that other devices can smoothly pick up the workpiece. Then the first drive mechanism 3 drives the clamping mechanism 1 to retreat linearly to the first position and the clamping jaw assembly 11 is in the initial position, ready for the next loading.

[0044] In addition, after the clamping mechanism 1 clamps the cylindrical workpiece 10 and is driven by the second driving mechanism 4 to rotate to a vertical state, the support member 14 also abuts against the end face of the cylindrical workpiece 10, providing axial support for the cylindrical workpiece 10 to prevent the cylindrical workpiece 10 from sliding downward under the action of gravity, thereby causing the clamping mechanism 1 to fail in clamping and affecting the subsequent loading process.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
