With the advancement of science and technology, labor and other costs have increased, automatic production has replaced labor, and rapid and convenient high-speed connection technology has been developed and popularized. The connection of various parts, the connection of the control unit, the connection of the piping, etc. require joints, but the traditional methods are welding, thermal welding, threads, etc., which have low efficiency and poor stability. Therefore, the application of hydraulic joints based on quick-plug technology is developed and produced. Then, let's learn about the application of hydraulic joints in machinery manufacturing!
1. Application of hydraulic joints
The operation and control of the hydraulic joint cutting operation are realized through the connection of the two attached hydraulic lines with large flow (160L/min) and high pressure) 32Mpa) to the hydraulic line of the rescue robot itself through the automatic quick-change device on the wrist. Locking or unlocking of hydraulic shut-off
After tightening the automatic converter and hydraulic cutter, according to various working conditions, it is often necessary to rotate 360 relative to the front end of the auxiliary arm via the wrist rotation device. Therefore, the pipe joint is the relatively stationary end of the hydraulic oil, that is, the auxiliary arm. The installation position of the five-channel, high-flow, high-pressure, low-speed, and small-volume joint (hereinafter referred to as the five-channel rotary joint) is similar to the rotary joint of construction machinery. Therefore, the five oil filling ports of the five-channel joint need to be located at the end of the wrist swivel device and connected to the oil supply pipe of the rescue robot's own hydraulic pipeline at the front end of the jib. This is the fixed connection and will need to be cut unless the fully automatic changer needs to be replaced and removed from the front of the jib.
2. Application specifications of hydraulic joints
The 5 discharge ports of the hydraulic joint need to be located at the end of the automatic quick-change device on the wrist, and the 2 G1/4 discharge ports are 2 small flow (30L/min) to drive the 2 movable claws to lock or release the attachment. ) and high pressure) 32Mpa The other two G3/4 oil outlets are connected with the two hydraulic cylinders with large flow (160L/min) and high pressure) 32Mpa) attached to the hydraulic cutting machine, and the driver operates the hydraulic cutting machine in real time during work. Therefore, this connection requires high reliability, that is, the connection needs to be turned on when the lock is released.
3. The name of the hydraulic joint
Because the automatic replacement device of hydraulic joints meets the requirements of frequent replacement of accessories, this connection also needs to meet the requirements of frequent opening or closing. "Fully automatic" for a fully automatic changer means that the locking or unlocking of attachments is accomplished without human intervention, while the opening or closing of such connections is accomplished without human intervention. The pipe joint that meets this kind of movable connection can quickly connect or cut off the pipeline of gas medium and liquid medium without using tools (wrenches or pipe clamps) or special equipment. It is widely used and is an important part.
