Technical Field

[0001] This utility model relates to the field of clamping and handling technology, specifically a clamping mechanism. Background Technology

[0002] On the automobile assembly line, people operate robotic arms to handle and assemble tubular and bar-shaped parts. In some application scenarios, the postures of the parts during material handling and assembly are inconsistent, requiring adjustment of the parts' postures. At this time, a stable and reliable clamping mechanism is needed to effectively clamp the tubular and bar-shaped parts, while adjusting the posture to stabilize the parts' state. To this end, we propose a clamping mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide a clamping mechanism installed on the actuator of a power-assisted robot, which achieves clamping or releasing actions by extending or retracting the cylinder, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism, comprising: Main frame, cylinder, cylinder push block, connecting rod, gripper; The main frame is equipped with a power-assisted robotic arm; The piston rod of the cylinder is fixedly connected to the cylinder push block as a whole, and the cylinder push block is connected to the connecting rod through a hinge point; The gripper is connected to the main frame via a hinge point.

[0006] Preferably, one end of the positioning block is provided with a positioning groove with an angle greater than 125°, and the middle part of the positioning groove is arc-shaped.

[0007] Preferably, an anti-slip block is installed on the inner side of one end of the gripper, and the anti-slip block is made of polyurethane.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a cylinder-driven gripper to quickly clamp and release tubular and rod-shaped parts. It is easy to operate. The polyurethane anti-slip block on the inner side of the gripper, combined with the arc-shaped positioning groove of the positioning block, can stably clamp the parts, prevent slippage, and ensure stability during posture adjustment.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The main frame 1, cylinder 2, cylinder push block 3, connecting rod 4 and gripper 5 of this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0015] Please see Figures 1-2 As shown, this utility model provides a technical solution: a clamping mechanism, comprising: Main frame 1, cylinder 2, cylinder push block 3, connecting rod 4, gripper 5; Among them, the main frame 1 is equipped with a power-assisted robotic arm; The piston rod of cylinder 2 is fixedly connected to cylinder push block 3 as one unit, and cylinder push block 3 is connected to connecting rod 4 through hinge point; The gripper 5 is connected to the main frame 1 via a hinge point.

[0016] A positioning block is installed on one side of the main frame 1 between the hinge points of the two grippers 5. One end of the positioning block is provided with a positioning groove with an angle greater than 125° and the middle of the positioning groove is arc-shaped. An anti-slip clamping block is installed on the inner side of one end of the gripper 5, and the anti-slip clamping block is made of polyurethane.

[0017] This technical solution involves preparing the main frame 1, cylinder 2, cylinder push block 3, connecting rod 4, gripper 5, and accessories such as positioning block and polyurethane anti-slip gripper. Each component is inspected for deformation or damage. The sealing performance of cylinder 2, the flexibility of the hinge point rotation, and the secure installation of the anti-slip gripper are confirmed. The installation dimensions of the main frame 1 are verified to match the actuator of the robotic arm to ensure smooth subsequent installation. The opening and closing strokes of gripper 5 are confirmed to meet the clamping requirements of tubular and rod-like components. Next, the positioning block is installed on one side of the main frame 1 near the hinge point of gripper 5, ensuring the correct installation direction of the arc-shaped positioning groove. It is then secured with bolts or other fasteners to ensure a secure installation. Finally, polyurethane is installed on the inner side of one end of gripper 5 using adhesive or bolt connections. Ester anti-slip clamping blocks (it should be noted that the material of the anti-slip clamping blocks can be selected according to the usage, and the contact surfaces of the anti-slip clamping blocks and positioning blocks with the clamping parts can be provided with anti-slip textures, etc.) are used to ensure that the anti-slip clamping blocks are accurately positioned, fit tightly, and are not loose or offset. Next, the cylinder 2 is installed in the preset position of the main frame 1, so that the cylinder piston rod and the cylinder push block 3 are reliably fixedly connected. Through the hinge point, the cylinder push block 3 is connected to the connecting rod 4, the connecting rod 4 to the gripper 5, and the gripper 5 to the main frame 1 in sequence. The gap and rotation flexibility at the hinge point are adjusted, and an appropriate amount of grease can be applied to ensure smooth transmission. Then, the assembled clamping mechanism is installed on the actuator of the power-assisted robot through the main frame 1 to ensure a stable connection that can withstand the force and torque during clamping operations.

[0018] Debugging and Verification Operate the assisted manipulator, control the cylinder 2 to extend and retract, observe whether the gripping and releasing action of the gripper 5 is smooth, check whether the rotation of the hinge point, the transmission between the cylinder push block 3 and the connecting rod 4 are normal, and whether there is any jamming or abnormal noise; test the positioning effect of the positioning block on the tube and rod parts, and verify the stability of the parts in the positioning groove when gripped. Typical tubular and bar components were selected for clamping tests to simulate the operation process of material handling, posture adjustment, and assembly. The anti-slip effect of the anti-slip blocks was checked, and it was observed whether the components would slide or shift. The stability of the clamping mechanism during posture adjustment was evaluated. The clamping compatibility of tubular and bar components of different specifications was tested. To address issues such as sluggish movement and unstable clamping discovered during debugging, adjustments were made to the hinge point clearance, cylinder stroke, positioning block position, or the adhesion of anti-slip clamps. The adjusted mechanism underwent functional and stability testing again until it met the operational requirements of the automotive assembly line.

[0019] In summary, the clamping mechanism can be assembled, debugged, and applied. With its stable clamping performance and flexible posture adjustment adaptability, it can help to carry out the handling and assembly operations of tubular and bar components on the automotive assembly line efficiently.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
