Description

Technical Field

[0001] The utility model belongs to the technical field of cylinders, and in particular relates to a cylinder protection device for a welding fixture. Background Art

[0002] Cylinder refers to a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. Air converts heat energy into mechanical energy by expanding in the engine cylinder; gas is compressed by the piston in the compressor cylinder to increase pressure. The shell of turbine, rotary piston engine, etc. is usually also called "cylinder". Application fields of cylinder: printing (tension control), semiconductor (spot welding machine, chip grinding), automatic control, robot, etc. The cylinder is composed of cylinder barrel, end cover, piston, piston rod and seal, etc. The piston is the pressure-bearing part in the cylinder. In order to prevent the left and right chambers of the piston from blowing gas into each other, a piston seal is provided. The wear-resistant ring on the piston can improve the guiding property of the cylinder, reduce the wear of the piston seal, and reduce friction resistance. The wear-resistant ring is made of polyurethane, polytetrafluoroethylene, cloth-inserted synthetic resin and other materials. The width of the piston is determined by the size of the seal and the necessary length of the sliding part. If the sliding part is too short, it is easy to cause early wear and jamming. The piston is commonly made of aluminum alloy and cast iron. The piston of a small cylinder is made of brass. During the use of the cylinder used in the welding fixture, welding slag will splash from the metal product during the welding process. The splashed welding slag can easily enter the cylinder and damage the cylinder, reducing the use effect of the cylinder. Therefore, a welding fixture cylinder protection device is needed to protect the cylinder. Utility Model Content
