Description

Technical Field

[0001] The utility model relates to the technical field of plastic gasket processing, in particular to a portable positioning device for plastic gasket processing. Background Art

[0002] Gaskets are mechanical seals between two objects, usually used to prevent leakage due to pressure, corrosion, and natural thermal expansion and contraction of the pipeline. Since the machined surface cannot be perfect, the use of gaskets can fill the irregularities. Gaskets are usually made of sheet materials such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic polymers (such as polytetrafluoroethylene). Gaskets for specific applications may contain asbestos.

[0003] At present, during the installation of some parts and equipment, gaskets are usually pre-installed to play an anti-slip role and improve the installation effect. For such usage scenarios, the main function of the gasket is the surface at both ends. Therefore, in order to further improve the use effect of the gasket, it is usually necessary to perform surface treatment on the produced gaskets, such as adjusting the roughness of the gasket surface, which requires the use of grinding equipment to grind its surface. In order to ensure the stability of the grinding process, a positioning and fixing device is usually used to locate the position of the gasket. Traditional positioning devices often have a certain degree of freedom, that is, in order to adapt to gaskets of various sizes for use, but at the same time, it also causes the positioning device to require a certain amount of action time each time it is positioned, and when the gasket is positioned and clamped, a thrust is generated on the gasket, causing damage to its surface, which is not conducive to improving the positioning efficiency and effect of the gasket. In view of this, we propose a portable positioning device for plastic gasket processing. Utility Model Content
