Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical claw technical field especially relates to a power pipe fitting elbow processing mechanical claw. BACKGROUND

[0002] In the power transmission and distribution system, power pipe fitting elbow as an important connecting component, bears the key role of changing the pipeline direction, connecting different diameter pipeline. With the rapid development of electric power industry, the demand for power pipe fitting elbow is increasing, at the same time, higher requirements are put forward to its processing precision and production efficiency. The traditional power pipe fitting elbow processing method adopts manual operation, this way not only has great labor intensity, low efficiency, and also is difficult to guarantee the quality and consistency of products. In recent years, with the progress of automation technology, more and more power pipe fitting elbow processing enterprises begin to introduce mechanical equipment, especially mechanical claw, to improve production efficiency and product quality.

[0003] In practical application, the existing power pipe fitting elbow processing mechanical claw still has many deficiencies. The most prominent problem is that these mechanical claws generally lack sufficient adaptability, and cannot effectively clamp power pipe fitting elbows of different bending diameters. Specifically, since the bending radius, diameter size and material properties of power pipe fitting elbows are different, the traditional mechanical claw design can only be applied to products within a certain range, and once the elbow exceeds this range, it is difficult to achieve stable and reliable grabbing and positioning. This limitation not only limits the application range of the mechanical claw, but also increases the workload of enterprises in the production process to frequently replace the mechanical claw or adjust the equipment parameters, thereby affecting the overall production efficiency and cost control.

[0004] The processing environment of power pipe fitting elbow is relatively complex, which may involve extreme conditions such as high temperature and high pressure, which puts higher requirements on the material selection and structure design of the mechanical claw. The existing mechanical claw is mostly made of metal material, which has good strength and durability, but may have corrosion, deformation and other problems in some special environments, affecting its long-term use performance. At the same time, in order to ensure the processing precision, the mechanical claw also needs to have high position control precision and clamping force stability, and the existing technology needs to be further improved in this regard. For example, when grabbing power pipe fitting elbows made of slender or light materials, the traditional mechanical claw is easy to cause workpiece deformation due to excessive clamping force, or cause workpiece slipping due to insufficient clamping force, which seriously affects the final quality of the products.

[0005] In view of the above problems, it is urgent to develop a new type of mechanical claw that can adapt to the processing needs of power pipe fittings elbow with various bending diameters. The ideal new type of mechanical claw should have the following characteristics: first, it should have high flexibility and adjustability, and can quickly adapt to different specifications of power pipe fittings elbow through simple adjustment or setting, without frequent replacement of mechanical claws or significant adjustment of equipment parameters. Secondly, the new type of mechanical claw should use advanced materials and technologies to improve its reliability and durability in harsh working environments, for example, special alloy materials resistant to high temperature and corrosion can be selected, and surface treatment processes can be combined to extend the service life of the mechanical claw. Thirdly, in order to ensure the processing precision, the new type of mechanical claw should also integrate a precise position control and force feedback system to achieve precise control of the clamping force in different working conditions, avoiding unnecessary damage to the workpiece.
