When placing the suspension pipe, the suspension pipe contacts with buffer block 32 earlier to extrude buffer block 32, make buffer block 32 extrusion spring and downstream, at this in-process, can cushion through the spring, reduce because of suspension pipe directly falls to supporting shoe 3 on, the probability that the supporting shoe 3 or the impaired condition of suspension pipe that the great striking leads to appear takes place.
After the welding is finished, the welded suspension pipe is taken down, and the mobile station 2 is pushed towards the direction close to the workbench 1, so that the fixture block 21 on the mobile station 2 is inserted into the clamping groove on the workbench 1 and moves towards the inside of the clamping groove. Along with the movement of the clamping block 21, when the clamping block 21 contacts with the sliding block 12 sliding out of the sliding groove 11, the sliding block 12 is gradually extruded, so that the sliding block 12 slides into the sliding groove 11, and the clamping block 21 smoothly slides; and after the fixture block 21 slides to the limiting groove and is positioned below the sliding block 12, the blocking force applied to the sliding block 12 disappears, so that the sliding block 12 can slide out of the sliding groove 11 under the action of spring reset and self gravity and is positioned in the limiting groove to limit the fixture block 21, and the mobile station 2 is fixed on the workbench 1.
Example 2:
Communicating pipe 5 all includes from last to violently managing first violently pipe, vertical pipe and the second that communicates in proper order down, and first violently manage and be located supporting shoe 3 tops, and the second is violently managed and is linked together with installation piece 4. Vertical sliding connection has the piston in the installation piece 4, and also lateral sliding connection has the piston in the second violently pipe, and it has the liquid of communicating to be located to annotate between two pistons in communicating pipe 5 and the installation piece 4, and oil is chooseed for use to the liquid of communicating in this embodiment. The bottom of the push rod 321 is fixed on the piston in the mounting block 4, the piston in the second transverse pipe is fixed with a clamping rod 51, and one end of the clamping rod 51 facing the mounting block 4 is provided with a clamping block 52.
The specific implementation process is as follows:
when placing the suspension pipe of treating welding, suspension pipe extrusion supporting shoe 3 moves down to drive push rod 321 to move down, consequently extrude the piston in the installation piece 4, the piston extrudes the intercommunication liquid, makes the piston that the intercommunication liquid promoted the second cross tube move, and then drives clamping rod 51 and remove, thereby treats welding end clamp tightly, fixed with the suspension pipe, improves the welded precision.
Example 3:
The specific implementation process is as follows:
the support platform 6 is arranged to improve the support stability of the suspension pipe, so that the welding precision is improved. Meanwhile, when the hanging pipe with the corner is welded, the corner can have an irregular shape, so that after the hanging pipe is installed, the hanging pipe can automatically rotate under the action of the irregular end, and the shape of the welded hanging pipe is not in line with the requirement; and set up a supporting bench 6 and can support the corner of suspension pipe, and then take place to rotate the problem appearance that influences the welding position precision after avoiding appearing the suspension pipe installation.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications should not be construed as affecting the performance of the invention and its practical application.
