Technical Field

[0001] The utility model relates to the field of cylinders, in particular to a special welding cylinder. Background Art

[0002] A cylinder is a cylindrical metal part that guides the piston's linear reciprocating motion within the cylinder. Air expands in an engine cylinder, converting thermal energy into mechanical energy. Gas is compressed in a compressor cylinder by a piston, increasing its pressure. The casing of turbines and rotary piston engines is also commonly referred to as a "cylinder." Applications of cylinders include printing (tension control), semiconductors (spot welding machines, chip grinding), automated control, robotics, and more.

[0003] When welding automobile sheet metal, a dedicated welding cylinder is required. However, existing welding cylinders are heavy, time-consuming and labor-intensive to install, and have slow opening stroke conversion speeds, large gas consumption, and unstable welding output force.

[0005] To achieve the above object, a special welding cylinder is provided, comprising a cylinder body, wherein a front air port is provided through one end of the outer side of the cylinder body, a rear air port is provided on one side of the front air port, and the rear air port is also provided through the cylinder body, a spring is fixedly connected to one end of the inner side of the cylinder body, and a piston is fixedly connected to the other end of the spring;

[0006] The other end of the piston is fixedly connected to a piston rod, and the piston rod is arranged to penetrate the interior of the cylinder body. A sealing member is provided at the connection between the piston rod and the cylinder body.

[0007] According to the special welding cylinder, the other end of the outer side of the cylinder body is fixedly connected with a mounting bracket.

[0008] According to the dedicated welding cylinder, the other end of the piston rod is fixedly connected to a connecting piece.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. When the cylinder designed by this patent is switched in stroke, a spring is installed inside the cylinder body. After the front end of the piston is exhausted, the spring pushes the piston to move. The rear end cavity does not require compressed air. The switching speed is relatively fast, the requirement for compressed air volume is low, the cylinder gas consumption is small, and the output force is relatively stable.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0017] See also Figure 1-2 The utility model provides a technical solution: a special welding cylinder, including a cylinder body 1, a front air port 8 is provided at one end of the outer side of the cylinder body 1, and a rear air port 4 is provided on one side of the front air port 8. The front air port 8 and the rear cylinder port 4 are connected by a pneumatic reversing valve to complete the reversing operation, and the rear air port 4 is also provided on the cylinder body 1, and a spring 5 is fixedly connected to one end of the inner side of the cylinder body 1, and a piston 6 is fixedly connected to the other end of the spring 5. Under the action of the spring 5, the piston 6 can have the function of automatic reset. When the stroke is converted, since the spring 5 is installed inside the cylinder body, after the front air port 8 in front of the piston is exhausted, the spring 5 pushes the piston to move. The rear end cavity does not require compressed air, the conversion speed is relatively fast, the requirement for compressed air volume is low, the cylinder gas consumption is small, and the output force is relatively stable.

[0018] The other end of the piston 6 is fixedly connected to a piston rod 7, which is arranged throughout the interior of the cylinder body 1.
