Description

Technical Field

[0001] The utility model relates to the technical field of grabbing mechanisms, and more specifically, to a grabbing mechanism for metal component processing. Background Art

[0002] In the existing technology, the existing grasping mechanism often lacks sufficient adaptability and flexibility when facing metal parts of different types, shapes and sizes. A single grasping method is difficult to meet the increasingly diverse processing needs. Frequent replacement and adjustment of grasping tools is not only time-consuming and labor-intensive, but may also affect the stability and precision of the equipment. In order to solve this problem, we can integrate multiple grasping methods into the grasping mechanism, such as mechanical grippers and adsorption grasping structures. Mechanical grippers use mechanical force to clamp and fix the workpiece, which is suitable for workpieces of regular size and shape, while the adsorption grasping structure uses vacuum suction or magnetic force to grasp workpieces with irregular surfaces or special materials. By reasonably arranging and switching these grasping structures, the grasping mechanism can achieve flexible grasping of different workpieces, greatly improving the adaptability and production efficiency of the equipment.

[0003] In the process of grasping and transferring metal parts, accidental falling of workpieces is a common and serious problem, which not only affects the processing quality and equipment stability, but may also cause harm to the staff. The falling of workpieces is usually caused by factors such as insufficient grasping force, vibration impact, collision interference, etc. In order to reduce the risk of falling, we can start from multiple aspects. First, optimize the design of the grasping structure to improve the grasping force and reliability. Secondly, introduce buffering, vibration reduction and other measures in the motion mechanism and control system to smooth the motion trajectory and reduce vibration impact. Thirdly, reasonably plan the equipment layout and motion path to avoid unnecessary collisions and interference, and promptly detect and correct abnormal situations. Through these comprehensive measures, the risk of workpiece falling can be minimized to ensure the safety of the production process.

[0004] The transmission of the clamping arm in the grasping mechanism is also an issue worthy of attention. At present, many grasping mechanisms use gear transmission to drive the opening and closing and rotation of the clamping arm. Although the gear transmission has high force transmission efficiency and compact structure, the wear and clearance of the gear pair will gradually increase during long-term use, affecting the transmission accuracy and stability. At the same time, the gear pair also needs regular lubrication and maintenance to reduce wear and noise. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a gripping mechanism for metal parts processing, which has the following beneficial effects:

[0018] 1. The clamping assembly realizes flexible grasping and precise positioning of metal parts of different sizes and shapes through the ingenious coordination of the rotating arm, driven arm, bottom plate, meshing gear, motor, fixed plate and lifting cylinder. The linkage design of the rotating arm and the driven arm expands the grasping range and angle and adapts to the various workpiece placement states. At the same time, the motor drives the meshing gear to drive the active arm and the driven arm to realize clamping and releasing actions, thereby improving the controllability and reliability of clamping. The introduction of the lifting cylinder and guide rod further enhances the lifting capacity and stability of the clamping assembly. Compared with the traditional single clamping method, the flexibility and adaptability of this clamping assembly are greatly improved, which can meet the grasping requirements of different workpieces and improve the versatility and production efficiency of the equipment.

[0019] 2. The resisting component realizes reliable support and protection for the clamping process through the innovative combination of fixed box, electric push rod and liner. Driven by the electric push rod, the liner can be flexibly extended and positioned to effectively support and limit the clamping parts of the active arm and the driven arm, which not only prevents the workpiece from accidentally falling off during the clamping process and improves the stability of clamping, but also avoids direct collision between the clamping jaws and the workpiece, extending the service life of the clamping jaws. The coordinated design of the movable pulley and the fixed box further improves the stability of the liner movement and the positioning accuracy, improves the safety and reliability of the clamping process, and provides reliable guarantee for the stable progress of the production process.

[0020] 3. The lubrication component realizes automatic lubrication of the meshing gear transmission parts through the sophisticated design of the oil filling pipe, oil filling plug, abutment block, arc plate, abutment spring and oil outlet, effectively solving many disadvantages of traditional manual lubrication. After the lubricating oil is injected, as the meshing gears rotate, the abutment block squeezes out a proper amount of lubricating oil from the oil outlet under the action of the arc plate and abutment spring, and evenly coats it on the meshing surface of the gear. This design not only reduces manual intervention and improves the automation level of the equipment, but also realizes the quantitative supply and uniform distribution of lubricating oil, prolongs the service life of the gears, and reduces wear and noise. Compared with the traditional manual lubrication method, the automation level and lubrication effect of this lubrication component have been significantly improved, providing a strong guarantee for the long-term and reliable operation of the meshing gear transmission.
