Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic devices, in particular to a train synchronous clamping pneumatic device. Background Art

[0002] In the past, train valve pneumatic devices could not be synchronized due to various problems. They were often started individually for unilateral control. The cylinder of the one-way clamping mechanism operated by venting to extend forward and closing to retract. The direction of the cylinder was from outside to inside, so only unilateral clamping could be controlled. Clamping was performed at one time by two cylinders. Moreover, the clamping mechanism could only be used for individual valve types and could not achieve multi-compatibility. The device required two steps and multiple model positions to drive to meet the needs.

[0003] It can be seen from this that although the existing clamping equipment also uses pneumatic devices, it cannot operate synchronously. It can only clamp one side of a single product and then start clamping the other side. Not only does it add a certain number of operating steps and processes, resulting in a large amount of waste of working time, but it also greatly reduces safety and has certain operational risks.

[0023] Specific working principle:

[0024] This device performs synchronous clamping by linking the connecting rod 5 through the cylinder 3. The cylinder 3 is executed from the outside to the inside, thereby realizing synchronous clamping. First, the cylinder 3 is ventilated. At this time, the front end of the cylinder 3 will push the synchronous plate 4 to move forward, and the connecting rods 5 on both sides will move forward together with the synchronous plate 4. At this time, the clamping piece 12 at the tail end of the connecting rod 5 will pull the tail end of the clamping piece 6, and the front end of the clamping piece 6 will be synchronously opened through the curved surface tension. At this time, the device is in a loosened state; then the cylinder 3 is deflated. After deflation, the cylinder 3 contracts, and the synchronous plate 4 will drive the connecting rods 5 on both sides to retract together, and the inner wall surface of the tail end of the clamping piece 6 is pressed by the fixed seat 11 at the tail end of the connecting rod 5, and the clamping piece 6 is closed by the curved surface tension. At this time, the device is in a clamped state.
