[0033] The spring 604 is arranged between the limiting baffle 606 and the box body 1, and a torsional spring is arranged between the limiting baffle 606 and the rotating block 607, so that the rotating block 607 is quickly reset after rotating once, and the four-jaw clamping mechanism 3 is internally provided with a groove 1, and the spring 604 resets the limiting baffle 606 after moving once.

After the rotating plate 701 rotates, the spring rod 702 is used for resetting the rotating plate 701, the inclined surface of the sliding buckle 703 is passed, the sliding buckle 703 slides again, the rotating plate 701 reenters the sliding buckle 703, and the resetting effect of the rotating plate 701 is achieved.

[0038] The limiting device of the protective door comprises a protective door 14, the protective door 14 is slidably installed on the surface of the box body 1, a limiting groove is arranged on the bottom of the protective door 14, a push rod 12 is penetrated through the inside of the thimble 6, a groove three is arranged on the bottom of the box body 1, a sliding rod 13 is slidably installed on the bottom of the box body 1, the sliding rod 13 is slidably installed in the sliding groove of the box body 1, a limiting block 803 is arranged on the surface of the sliding rod 13, an inclined surface is arranged on the surface of the sliding rod 13, a spring four 801 is arranged between the limiting block 803 and the sliding groove, the spring four 801 resets the sliding rod 13 when the welding bed stops working, and a fixed baffle 802 is fixedly installed on the back of the protective door 14.

[0039] When the embodiment works: the staff will put the cylinder from the feeding box 7 into the polishing device 10 inside to polish, and after polishing, the polished cylinder will be conveyed to the rotating plate 701. When two cylinders are conveyed to the rotating plate 701, the rotating plate 701 will lose the control of the sliding buckle 703 through the cylinder extrusion, and the rotating plate 701 will rotate downward, so that the two cylinders slide downward to the unloading area. After the cylinder slides down, the rotating plate 701 will rotate upward under the rebounding force of the spring rod 702. At this time, the rotating plate 701 passes through the inclined surface of the sliding buckle 703, so that the sliding buckle 703 slides outward. When the rotating plate 701 resets, the spring three 704 will reset the sliding buckle 703, so as to re-lock the rotating plate 701, realizing the effect of unloading two cylinders at the same time.

[0040] When the ejector pin 6 moves forward and pushes the cylinder to be processed on the welding bed, the push rod 12 fixed on the surface of the ejector pin 6 will move forward at the same time. At this time, the push rod 12 will touch the inclined surface of the sliding rod 13 at the bottom of the box 1, so that the sliding rod 13 slides to the direction of the protective door 14 through the sliding groove at the bottom. When the sliding rod 13 slides to a certain distance, the limiting block 803 will be clamped in the fixed baffle 802 arranged at the back of the protective door 14, so that the welding bed works, and the protective door 14 will not move, thereby achieving the effect of protecting the worker from being injured by accidentally touching the protective door 14 and moving the protective door 14. When the welding bed finishes processing, the ejector pin 6 will continue to move forward and send the processed cylinder out from the right side of the box 1. After the cylinder is sent out, the ejector pin 6 will move backward. When the ejector pin 6 resets, the sliding rod 13 will reset through the fixed spring four 801 between the bottom limiting block 803 and the sliding groove, so as to release the limitation of the protective door 14, so that the protective door 14 restores the movable state, thereby achieving the effect that the protective door 14 is limited to move when the welding bed works, and is released to move when it does not work.

[0041] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
